Working Principle

circulation heat sink and returns to the external environment through the air exhaust

vents on the external circulation heat sink. The heat exchange between the internal and

external environment is implemented so far.

The TCUA control box controls the refrigeration chip in the TEC module to heat the

internal circulating air. The internal circulation fan draws the air inside the battery

compartment into the internal circulation heat sink. The internal circulation heat sink

heats the air and then returns the heated air to the battery compartment through the air

exhaust vents. Meantime, the external circulation fan operates according to control logic

and draws natural air into the external circulation heat sink. The air gives out heat and

returns to the external environment through the air exhaust vents on the external

circulation heat sink.
