3 ANTSPACE HK3V6 Container Liquid Cooling System Overview
The container liquid cooling system aims to continuously provide cooling liquid that meets the pressure, temperature, and flow requirements for the heat dissipation unit of the internal high computing power server, ensuring a good working environment for the load.
There are three types of heat dissipation options for container liquid cooling systems: evaporative cooling (dry wet combined cooling tower), water-water heat exchange (plate exchange component), and forced air cooling (dry cooling tower). The internal cooling medium can be selected according to the local environmental temperature, such as suitable antifreeze, deionized water, or pure water.

4.2 Working Principle

Pump Station
The pump station provides two cooling liquids that meet the requirements for temperature, pressure, flow rate, and medium to the liquid distributor components. After two stages of liquid separation, the water separator delivers the cooling liquid to the water-cooled plate, which takes away the heat inside the equipment. The heated cooling liquid enters the cooling tower for forced heat exchange with the external air, or enters a plate heat exchanger for heat exchange with the external cold source. The cooled cooling liquid is then transported to the water-cooled plate again through the pump station and water separator components for circulation, thereby taking away the heat inside the heating load and ensuring that the heating load operates in a good environment.
Dry Wet Tower

2

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual The dry wet tower for both dry and wet use should be used for both dry and wet working conditions. The working principle of wet working conditions is to use water and air as cooling media, and use the evaporation of some cooling water to carry away the heat released by the cooling liquid during the flow process inside the coil. Internally equipped with: spray device, serpentine condensing coil, (filler heat exchange layer) dehydrator, bottom with a water collection tank, external spray pump, and top with an axial flow fan. During operation, cooling water is pumped from the spray pump to the upper part of the condensing disc and the liquid condensed by the cooling water outside the tube flows out from the lower part of the condensing disc. After absorbing the heat of the coolant, a portion of the water evaporates into water vapor, which is sucked away by an axial flow fan and discharged into the atmosphere. The non evaporative cooling water drips into the lower collection tank for circulation by the spray pump. The axial flow fan draws air from the top, strengthening air flow, causing the water collection tank to bear negative pressure, reducing the evaporation temperature of water, accelerating water film evaporation, and strengthening the heat release of the condensing coil. The function of a dehydrator is to block non evaporative water droplets in the air and allow them to flow back to the collection tank, in order to reduce the consumption of cooling water. In addition, a floating ball valve is also installed in the water collection tank. When the water continuously evaporates and consumes, the floating ball valve automatically opens to provide supplementary spray water. The working principle of dry working condition is to forcibly exchange heat between the cooling liquid with high temperature from the water-cooled plate and low-temperature air, and the cooling liquid with reduced water temperature enters the system again through the pump unit for heat dissipation.
Plate Heat Exchanger
During the operation of a plate heat exchanger, a thin rectangular fluid channel is formed between each heat exchange plate. The cold and hot heat exchange media enter these narrow and tortuous flow channels through the holes at the four corners of the plate. The ripples on the plate enhance the stiffness of the plate and also enhance the turbulence of the fluid. Two types of media form a parallel flow or a reverse flow between the plates, and heat exchange is carried out through the intermediate layer plates to achieve the purpose of use.
Dry Tower
Similar to the dry wet tower, the dry tower uses a power fan to force air convection to achieve heat exchange between the air and the internal circulating medium, thereby achieving overall heat dissipation.

It is prohibited to put debris inside the equipment to ensure that the fire passage is always unobstructed.
8.2 System Pressurization
After the on-site installation of equipment and pipelines is completed, a 7 bar air pressure test should be conducted first, with the pressure maintained for at least 12 hours. Then conduct a 7 bar water pressure test, with the pressure maintained for at least 30 minutes. Check if there is any leakage in each pipeline and interface. If there is no leakage and the pressure reading decreases by less than 5%, it indicates that the on-site installation inspection is qualified. The pressurization process is as follows:
8.2.1 Preparation Before Pressurization

1. Prepare hoses and air pumps (recommended brand: OUTSTANDING, model 2200W- 40L. Selection basis: the internal volume of the system is about 1.5 m3, and the air pump with corresponding exhaust volume is selected according to time requirements; the maximum output air pressure is required to be above 8 bar, and 10 bar is optimal);
2. Connect the external pipelines according to the previous chapters.
   18

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual 3) Check if all the plugs on the automatic exhaust valves on the internal and external connection pipelines of
the container are closed. Automatic exhaust values include V302&V303 on the water distributor 7, V301 on the degassing tank, V304 on the expansion tank, manual exhaust valve V701, and cooling tower exhaust valve V306.By screwing the top nut of the automatic exhaust valve, the automatic exhaust valve can be opened/closed. 4) Check whether the safety valve ball valve V410 and expansion tank ball valve V105 are closed, and check whether each liquid filling and drain valve is closed. The water distributor has 4 drain valves (V205-V208), the pump station has 1 filling/drain valve (V104), 1 drain valve (V201), and 1 filling valve (V209).

The inspection method is as follows: · Check for leaks by seeing, listening and touching. · Add water to one of soap, laundry detergent, and detergent to make soap solution, and apply it to suspected leakage points, especially at the joints. The areas with bubbles and bulges are the leakage points.
8.3 System Liquid Replenishment
During the installation of the external pipeline, it is necessary to check whether the filter Z01 in the external pipeline 06 is intact.
The spray water inside the cooling tower adopts tap water or softened water, and a tap water pipe (DN40) is installed on site. It is recommended to choose appropriate antifreeze or purified water based on local climate conditions as the circulating media in cooling tower and container.
Firstly, add liquid to the system with a liquid filling pump. When the return pressure reaches the required value, stop adding liquid to the system. Switch the pipeline switch, and start the liquid filling pump to add liquid to the water tank. When the liquid level in the water tank reaches the required height, switch the pipeline switch, and the system will automatically run.
The specific liquid filling procedure is as follows: 1) Preparation: Prepare materials and tools, and open all exhaust valves of the system (open the manual
exhaust valve of the system and the manual exhaust valve on the cooling tower for the first liquid filling). 2) System liquid replenishment: Replenish the system with liquid filling pump P11. 3) Water tank replenishment: Replenish the water tank with liquid filling pump P11. 4) Regular replenishment of water tank: Replenish the water tank with the liquid filling pump P11 or through
the manual filling port on the top of the water tank.
8.3.1 Preparation

1. Prepare the coolant. 2) Connect the external pipeline according to the previous chapters. Check if all the plugs on the automatic exhaust valves on the internal and external connecting pipelines of the container are open (see !and Figure 8-7 Schematic diagram of valve opening and closing 3) ). Open the filling valve V209 and close the drain valve V201 (see Figure 8-3 Location of the exhaust valve in
   container system and Figure 8-4 Water distributor drain port 4) ). 5) Open the exhaust ball valve V702 on the top of the water tank to ensure that the water tank is connected to atmospheric pressure (as shown in Figure 8-12).
   23

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual 6) Open the manual exhaust valve V701 of the system and connect the PU pipe to the quick connector on the
water tank (to accelerate the first liquid filling). Switch the exhaust valve of the cooling tower to the manual exhaust valve (as shown in Figure 8-12 Water
tank valve 7) ).
Figure 8-12 Water tank valve
Figure 8-13 Cooling tower exhaust valve
8.3.2 System and Water Tank Replenishment

1. Replenish the system and water tank C21 with the liquid filling pump P11.
2. Find an external water source (with a certain pressure), and connect the hose to liquid filling/drain port V104 on the container. Fill the connecting pipeline with liquid for the first liquid filling (until water flows out). Find the liquid filling port outside the container and plug in the hose (at the side door of the container). Then, connect the external water tank to the liquid filling pump P11.
   24

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual
3) Open the exhaust valve of the liquid filling pump (Allen wrench), switch to manual mode on the touch screen, and open the solenoid valve V202. After water is discharged, close the manual exhaust valve of the liquid filling pump.
Close solenoid valve V202, switch to manual mode on the touch screen, and open the “Manual Liquid Replenishment” mode “External System” of the liquid filling system, which means adding liquid to the system.
Open “External C21”, which means adding liquid to the water tank C21 externally, as shown in Figure 8-14 Distribution of solenoid valves in the liquid filling system
4) . 5) When adding liquid to the system, pay attention to whether there is water flowing out of the exhaust valve of the cooling tower and the manual exhaust valve of the system. When there is water flowing out, it indicates that the system has been fully filled. Then, close the manual exhaust valve of the cooling tower, open the automatic exhaust valve, and close the manual exhaust valve 701 of the system. 6) When the static pressure reaches 0.7 bar (refer to Figure 8-16, touch screen reading) or above, the circulation pump can be started for 10 seconds (without stopping the liquid filling pump), and then the circulation pump can be stopped. 7) Continue to add liquid and repeat for twice to ensure that 1.3-1.5 tons of coolant are added. 8) When the static pressure reaches 1.0-1.5 bar, stop adding liquid (observe the reading of the main interface pressure sensor PT02, as shown in Figure 8-16). 9) Turn on the circulation pump P01 again to circulate the coolant in the system, ensuring that all automatic exhaust valves are in open state. 10) Due to the first liquid filling and the presence of gas in the system, the discharge of gas during the water pump circulation will cause a decrease in pressure in the system. At this time, the liquid filling function is turned on, and the water tank replenishes the system to ensure that the return pressure is between 1.0 and 1.5 bar. 11) After the above operation is completed, the system back pressure (pressure gauge PI03/return pressure sensor PT02) will be stabilized at 1-1.5 bar and for normal operation. Automatic mode can be turned on and the computing power server can be turned on for operation.

8.3.3 Regular Replenishment of Water Tank
When water tank C21 needs to be replenished with a small amount of coolant, the following methods can be referred to:
Method 1: Same as the first liquid filling, connect the liquid filling pump P11 to an external water source (with a certain pressure; fill the connecting pipeline), turn on the liquid replenishment mode, and externally add liquid to
26

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual the water tank C21.
Method 2: open the installation chuck of the exhaust valve on the top of the water tank (refer to Figure 8-12), and manually add liquid from the manual filling port to the inside of the water tank.
8.4 Electrical Wiring
The electrical system requirement for the equipment is TN-S three-phase five wire system. Due to the two distribution cabinets (A/B cabinets) inside the equipment, in order to ensure safe and stable operation of the equipment, two 500kW three-phase five wire cables (with a rated current of 1200A for the main switch) should be prepared in advance on site.

Figure 8-20 Cable connection diagram The cables are connected from the upper two openings on one side of the container exhaust fan, as shown in Figure 8-21 (note: it is necessary to use rainproof cloth and cover in the accessories for protection). The cables are connected from the top junction boxes of the two distribution cabinets and extend all the way to the corresponding copper bars. They are installed and fixed with screws (already installed at the copper bar openings).
Figure 8-21 Cable inlet holes 29

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual
There are grounding studs on both sides of the container, and the distribution cabinet should also be reliably grounded. Therefore, it is chosen to reliably ground the shell of the container and the shell of the distribution cabinet. When leaving the factory, the phase sequence of the equipment has been determined. After the equipment arrives at the site, it only needs to adapt to the phase sequence of the on-site substation.
The operation is as follows: connect the L1, L2, L3, N, PE three-phase and five wires of the substation to the distribution cabinet, power on the main switch of the main control cabinet, and observe whether there is a power failure alarm on the LCD screen; If there is a power failure alarm, please adjust the phase sequence of the three phases connected to the main control cabinet L1, L2, L3; If there is no fault alarm on the LCD screen, it can operate normally.
Due to the separation of the cooling tower and container, there are also three heat dissipation fans, a spray pump, a liquid level sensor, and a temperature sensor above the cooling tower.
After the positions of the cooling tower and container are fully determined, it is necessary to wire four motors and two sensors. The liquid level sensor and temperature sensor have been required to be installed in the designated positions. The indicating point (depression) of the liquid level sensor must face upwards.
One end of the cable container for the cold tower fan, spray pump, liquid level sensor, and temperature sensor is already connected to the terminal inside the cold tower control cabinet, and the other end is reserved inside the container. When it is necessary to flip the wire to the side of the cooling tower, the corrugated pipe metal joint, 10 meter weather resistant metal corrugated pipe, and 5 stainless steel straps in the equipment should be first identified.
All cable wiring locations are at the junction box on the side wall of the cooling tower. The order of the three cooling fans and spray cooling pumps is not specified. The wiring sequence is U, V, W (from left to right). The location of the cooling fan and junction box See Figure 8-22. The liquid level sensor is installed as shown in
Figure 8-22 Location of the fans and wiring box below. The wiring diagram is shown in Figure 8-23 Location of the liquid level switch and temperature sensor .
The wiring steps are as follows: 1: Disassemble the screw sleeve of the metal joint and divide it into two parts: the screw sleeve and the metal joint. 2: The end of the metal joint should be connected to a 10 meter weather resistant metal corrugated pipe and form a whole. 3: Inside the container, pass 6 cables through the screw sleeve and then through the reserved outlet hole (located at the bottom right of the inlet and outlet liquid pipe intersection).
30

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual 4: Thread these 6 cables through one side of the metal joint and the other side of the corrugated pipe. 5: Insert the metal joint into the reserved outlet hole of the container, where the outer part of the container is a metal joint and the inner part is a screw sleeve. Tighten the screw sleeve to the metal joint end and tighten it to a fixed torque to achieve good sealing effect. 6: When laying out metal corrugated pipes outdoors, they should follow the lower one of the interconnecting pipelines between the container and the cooling tower, and be fixed with 5 stainless steel straps included in the accessories. 7: The other end of the cable should be connected to the junction box left by the cooling tower. The correct wiring sequence should correspond one by one between the number tube of the cable and the number of the terminals in the junction box. 8: After the wiring is completed, it is necessary to start and debug the operation to ensure its correctness and good wiring.

8.5.2 Precautions for First Power of the System

After the entire system wiring is completed, the equipment can be powered on for debugging. However,

before powering on, it is necessary to use a multimeter to measure whether there is a short circuit between phase

wires, between phases wire and neutral wire, between phase wire and ground wire, and between neutral wire and

ground wire of the two power supplies. If not, it means it can be powered on normally. If any of the above short

circuits exist, the fault should be identified first and then powered on. After the front-end of the system is powered

on (the system itself is not yet powered on, and the main switch of the distribution cabinet and main control

cabinet are not closed), it is necessary to measure the voltage of the front- end to see if it meets the power

requirements of the equipment.

The power requirement for this device is AC400V ± 5%, 50/60Hz.

35

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual
8.5.3 System Power-on Sequence
After the front-end of the system is powered on and the voltage meets the requirements of the device, the system can be powered on at this time. 1: Firstly, power on the main control cabinet.
When the main control cabinet door is opened, first open QFWCU, and then open all circuit breakers inside the main control cabinet. QFP1 and QFPZ1 are switches for 24V power supply in PLC, QFP2 and QFPZ2 are switches for system 24V power supply, QFP3 and QFPZ3 are switches for 12V power supply, and QFP4 and QFPZ4 are switches for 5V power supply. After powering on, the screen and PLC on the cabinet door begin to work.
When the main control cabinet door is closed and the system needs to be powered on, first open all miniature circuit breakers and one molded case circuit breaker QFVF02 inside the cabinet, then close the cabinet door and open QFWCU through the cabinet door operating handle. At this point, the equipment has been powered on. Trained electricians can operate the system through a touch screen, set parameters, modify thresholds, change operating modes (automatic/manual), start and stop a certain motor separately, or operate automatically. At this point, the liquid cooling system can be run first, and the supply temperature can be controlled within the required temperature range before meeting the conditions for starting the high computing power server. 2: After the main control cabinet is powered on, according to the operation process of the control system, it is only when the liquid supply temperature is maintained near the target temperature that the high computing power server can be turned on. At this point, the circuit breakers in distribution cabinets A and B can be opened to start powering on the high computing power server.
The power on sequence of the distribution cabinet is as follows: First open MCB-A1 and A2, then other circuit breakers, and then start rows of high computing servers in an orderly manner as required. Due to a total of 210 high computing power servers, there are a total of 14 rows. When starting a high computing power server, the next row should be started at an interval of 20 seconds after starting one row (15 high computing power servers), and so on.
Caution
Please refer to Table 7-1 for the corresponding device and switch position numbers.
8.5.4 System Power-off Sequence
When the system needs to power off for some reason, as required, first disconnect the power supply of the high computing power server to ensure that the water temperature before and after the power outage is consistent,
36

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual which is equivalent to protecting the power module of the high computing power server. After the power outage of the high computing power server, the liquid cooling system is manually stopped through the touch screen. At this time, the water temperature will slightly rise, but it has no impact on the system. Finally, disconnect the main power supply of the main control cabinet and distribution cabinet, leaving the entire system in a completely powered off state.
The above practice is a safe power outage behavior. However, when a serious fault occurs in the system, the emergency stop button on the inner door of the container can be directly pressed, causing the main circuit breaker of the distribution cabinet and the main circuit breaker of the main control cabinet to trip instantly, leaving the system in a completely powered off state, facilitating professional maintenance work.
8.5.5 Personnel Responsibility Division
Responsibilities of general operation and maintenance personnel: General power on/off work (disconnecting or merging circuit breakers), system startup and shutdown (touch screen button operation), network cable detection and replacement. Professional electrician responsibilities: General power on and off work (disconnecting or merging circuit breakers), system startup and shutdown (touch screen button operation), network cable detection and replacement. When the equipment experiences short circuits, phase loss, reverse phase, sensor no display, corresponding equipment no response after circuit breaker closing, and abnormal motor operation, professional electricians are required to operate.
8.6 Touch Screen Operation

40

ANTSPACE HK3 V6 Hydro-cooling container &Dry-Wet Tower Product Manual
Figure 8-30 Manual control interface At this point, the motor and frequency converter to be operated can be started by jogging. In general, when the system needs to add liquid, it is necessary to manually start and corresponding electric valves, make-up pumps, and circulation pumps. However, before starting, it is necessary to ensure that the motor runs in the correct direction. Therefore, after powering on, turn on the 1 # exhaust fan and observe its running direction. When the wind blows out of the container, it indicates positive rotation. Before the equipment leaves the factory, all motors have been debugged and turned forward. Therefore, it is only necessary to observe the operating status of one motor. When the motor reverses, it is necessary to adjust the phase of the three-phase power input of QFWCU, that is, change the phase sequence of the two cables.

10.3.6 Maintenance Of Coolant

1. As the core unit of the container liquid cooling system, it is recommended to regularly track and record the coolant, at least once a year (PH value is tested every six months).
2. When purchasing coolant, it is necessary to focus on the relevant parameters in Table 10-1. If the requirements are not met, it is necessary to consider refilling and replacing the coolant as appropriate.
3. Regular testing of coolant focuses on PH value, and it is not recommended to use it when the PH value is below 7 (a PH indicator can be added to the coolant. When the PH is below 6.8, the coolant will change color for easy observation).
4. The coolant needs to be regularly tested, paying attention to freezing point, ethylene glycol ratio, total hardness, etc. In the later stage, attention should be paid to whether the content of elements such as Al, Fe, Cu increases, as an increase indicates that contact corrosion has already occurred.
5. It is recommended to regularly add corrosion inhibitors according to the supplier’s requirements to maintain the coolant.
