HEATER STRUCTURE AND WORKING PRINCIPLE
Working Principle
After the heater is started, the glow plug plug begins to work, the fuel pump
starts to supply fuel, and the combustion-supporting fan intakes air from
outside. Fuel is burned in the combustion chamber to generate heat, which is
taken away by the aluminum heat exchanger. Internal air driven by the heat
exchange fan passes through the surface of the heat exchanger to carry the
heat to where it is needed. The exhaust gas is discharged through the exhaust
pipe.
