Fin condenser

1. Copper tube: As a circulation pipe for heat transfer media (such as refrigerants), copper becomes the core heat transfer material due to its high thermal conductivity (thermal conductivity coefficient is about 400 W/m·K) and corrosion resistance.

2. Aluminum fins: Tightly wrapped around the outer wall of the copper tube through mechanical expansion or welding process to form a dense fin array. Aluminum significantly increases the heat dissipation surface area and improves the overall heat exchange efficiency due to its light weight (density is only 30% of copper) and low cost.

Function: In the refrigeration/heat pump system, the high-temperature and high-pressure gaseous refrigerant is condensed into liquid through heat exchange with the ambient air, releasing latent heat (such as the condensation latent heat of R410A refrigerant is about 200-250 kJ/kg), completing the key link of the refrigeration cycle

3. Structure and materials – Base tube: Usually a copper tube with a diameter of Φ5~15.88mm and a wall thickness of 0.32~0.41mm. Some of them adopt an internal fin design to enhance the heat transfer in the tube. – Fin: The thickness of the aluminum foil is 0.12mm, and a corrugated or serrated surface is formed by stamping to optimize the airflow disturbance. – Connection process: The copper elbow and the piping adopt a Φ7~8mm specification to ensure the sealing and pressure bearing capacity (such as the pressure test up to 30MPa).

4. Manufacturing process – Surface treatment: The copper tube is dipped in varnish or electrophoretic paint, and the aluminum fin is anodized to improve corrosion resistance. – Internal cleanliness: High temperature vacuum drying process ensures that the refrigerant flow path is free of impurities and passes leak detection.
