GF83.20-P-3123MCU Heating System Heat Exchanger, Component Description







1 Heating system heat exchanger

Location
The heater heat exchanger is located in the left of the front passenger footwell.

Task
The heater heat exchanger warms the air flow which is directed to the vehicle interior via the various air distribution vents.

Design
The heater heat exchanger consists of coiled pipes and slats in order to offer the largest surface possible for the heat output.

Function
Coolant heated by the engine flows through the heater heat exchanger.
The inflow is regulated by the thermostat of the cooling-water circulation. The heat is dissipated via the coiled pipes and lamellae made of aluminum towards the outside to the air blowing by, which is heated up in the process and then routed into the vehicle interior.
