-wrap-mode: nowrap;">The evaporator core is one of the core components of a vehicle's air conditioning refrigeration system.

Key Information

Function

It serves as the critical component for heat exchange within the air conditioning system: liquid refrigerant absorbs heat and vaporizes inside the evaporator, thereby cooling the air flowing through it to provide cool air inside the vehicle.

It works in conjunction with the air conditioning condenser to complete the refrigeration cycle of “compression - condensation - expansion - evaporation.”

Structural Features

Constructed entirely of aluminum, it consists of densely packed cooling fins and internal tubing to maximize heat exchange surface area.

Typically mounted within the vehicle's dashboard air ducts, the mounting bracket shown in the diagram secures its position within the ductwork.

Common Issues

Poor cooling performance or reduced airflow from vents may indicate a clogged or leaking evaporator core, requiring professional inspection.

After prolonged use, dust and mold may accumulate between fins, potentially causing unpleasant odors in the airflow. Regular cleaning is recommended.

Applications

Widely used in air conditioning systems of various passenger and commercial vehicles. The model shown is commonly found as original equipment in heavy-duty trucks (e.g., Sinotruk Howo, FAW J6)
