Purpose
The heater core heats passing air.
Function
A portion of the engine coolant is taken into the heater core to heat the air passing through the heater core.

Construction
The heater core consists of a tube which passes engine coolant, and the heat radiation fin.

Operation
The engine coolant warmed by the engine heat is sent to the heater core.
The air blown by the blower motor is warmed up by heat exchange when it passes through the heat radiation fin of the heater core.
