Freezer Cabinet Chest Refrigerator Aluminium Fin Copper Tube Evaporator Condenser Heat Exchanger Coil
The copper tube fin evaporator is a highly efficient heat exchange device. Its core structure is made of copper tube (base tube) and aluminum fin (extended surface) tightly combined through mechanical expansion or hydraulic expansion process. It significantly improves the heat exchange efficiency by increasing the heat transfer area (fin surface area + base tube surface area).
Products Description
The copper tube fin evaporator is a highly efficient heat exchange device. Its core structure is made of copper tube (base tube) and aluminum fin (extended surface) tightly combined through mechanical expansion or hydraulic expansion process. It significantly improves the heat exchange efficiency by increasing the heat transfer area (fin surface area + base tube surface area).
1. Structure and Materials
Base pipe: usually a copper pipe with a diameter of 5~15.88mm and a wall thickness of 0.28~0.41mm. Some parts use internal rib design to enhance heat transfer inside the pipe.
Fin: Aluminum foil thickness of 0.12mm, formed into a corrugated or serrated surface through stamping to optimize airflow disturbance.
– Connection process: The copper elbow and piping adopt a specification of Φ 7-8mm to ensure sealing and pressure bearing capacity (such as a pressure test of 30MPa).
2. Manufacturing process
– Surface treatment: Copper pipes are coated with clear varnish or electrophoretic paint, and aluminum fins are anodized to enhance corrosion resistance.
– Internal cleanliness: The high-temperature vacuum drying process ensures that the refrigerant flow path is free of impurities and passes leak detection
