Evaporator Core: Description and Operation
Air Conditioning
A/C Evaporator Core
NOTE: If an evaporator core leak is suspected, the evaporator core must be vacuum leak tested before it is removed.
The evaporator core is an aluminum plate/fin type heat exchanger 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 then moves out of the evaporator core through the evaporator
core outlet tube. Air from the blower motor is cooled and dehumidified as it flows through the evaporator core fins.
