Working Principle

air into the external heat sink to accelerate the airflow. The air absorbs

the heat and returns to the external environment from the air exhaust

vent of the external heat sink. The air exchange between the internal and

external environment is implemented so far.

The TCUA controls the TEC04C to heat the internal circulation air. The

internal circulation fan draws the air inside the battery compartment into

the internal heat sink. The internal heat sink heats the air and then

returns the heated air to the battery compartment from the air exhaust

vent. At the same time, the external circulation fan draws the external

circulation air into the external heat sink to accelerate the airflow. The

air gives out the heat and returns to the external environment from the

air exhaust vent of the external heat sink.
