Evaporator Core: Description and Operation

Air Conditioning

Evaporator Core

The evaporator core is an aluminum plate/fin type and is located in the heater core and evaporator core housing. A mixture of refrigerant and oil enters the bottom of the evaporator core through the evaporator core inlet tube and continues out of the evaporator core through the evaporator core outlet tube as a vapor. Air from the blower motor is cooled and dehumidified as it flows through the evaporator core fins.
