Air-cooled copper tube fin evaporator

The core of the black electrophoretic copper tube aluminum fin evaporator lies in its efficient heat exchange capacity and outstanding durability.

Efficient Heat Exchange: Its copper tube and aluminum fin structure uses processes such as hydraulic expansion to ensure close contact between the fins and the copper tubes, reducing contact thermal resistance and significantly improving heat transfer efficiency. The aluminum fins are often designed with double-flange louvers, which effectively agitate the air and create turbulent airflow, further enhancing heat transfer.

Frost-Free: This type of evaporator is typically a fan-cooled or frost-free type. Using a fan to force air flow, it resists frost formation, reducing the need for regular defrosting and ensuring consistent, stable cooling.

Key Advantages of Black Electrophoretic Paint:

Strong Corrosion Resistance: The electrophoretic paint layer evenly and densely covers all surfaces, even the smallest details, providing excellent protection for the metal substrate (especially the aluminum fins and copper tubes), effectively resisting corrosion from harsh environments such as moisture, acids, and alkalis.

Improved Durability: Its excellent corrosion resistance directly extends the life of the evaporator.

Aesthetics: The black appearance gives people a professional and high-quality feeling.

When choosing a black electrophoretic copper tube aluminum fin evaporator, consider the following:

Electrophoretic paint quality: Pay attention to the thickness of the electrophoretic paint (typically 12-30μm) and the corrosion resistance test standards (such as the number of hours in the salt spray test). A high-quality electrophoretic coating process ensures a uniform and strong paint film.

Fin type: Choose from various fin types, such as flat, corrugated, and windowed, depending on the required heat transfer efficiency and air flow.

Copper tube type: Internally threaded copper tubes enhance heat transfer efficiency on the refrigerant side and offer superior performance to plain tubes.

Cleanliness and internal quality: Ensure the evaporator’s interior is clean and free of impurities, has a low moisture content (e.g., residual moisture ≤ 20mg), and undergoes rigorous leak testing. This is crucial for long-term, stable system operation.

Customization capabilities: The supplier’s ability to customize to your specific requirements (such as size, shape, tube diameter, and fin spacing) is also crucial.
