Automotive Air Conditioning System Condenser (Fin Tube Type)

Automotive Air Conditioning System Condenser (Fin Tube Type)

A tube-fin condenser consists of four core components: heat exchange tubes, heat dissipation fins, manifolds, and end caps. These components work together to achieve efficient heat dissipation.

Heat Exchange Tubes: Mostly aluminum tubes (a few high-end models use copper tubes), with an inner diameter typically 5-7mm.

Heat Dissipation Fins: Made of 0.1-0.2mm thick aluminum foil, formed into a corrugated or open-window structure through stamping, and tightly fitted to the outside of the heat exchange tubes. The fin spacing is generally 1.5-3mm, ensuring smooth airflow while maximizing the heat dissipation area (fins contribute approximately 80% of the total heat exchange area).

Manifolds: One on each side, cylindrical or square aluminum tubes with internal baffles dividing the condenser into an "inlet zone," a heat exchange zone, and an outlet zone. They are responsible for evenly distributing gaseous refrigerant to each heat exchange tube and collecting the condensed liquid refrigerant for output.

End caps and interfaces: End caps are installed at both ends of the manifold to provide a seal; the end caps are equipped with a refrigerant inlet (connected to the compressor high-pressure pipe) and an outlet (connected to the expansion valve). Some models also integrate a dryer filter to filter impurities and moisture in the refrigerant.
