Aluminum Fin Heat Exchanger with Heater For Frost Free Refrigerator

Aluminum Fin Heat Exchanger is mainly used in no-frost refrigerator and is the key device in the refrigeration system. Its main features are: compact structure, large heat exchange area, strong air flow, big cool air density and high energy efficiency.

Description:

- Fin punched with flanging height 1.5mm, directly contact with aluminum tube, greatlyincreased heat exchange area &

exchange efficiency.

- Thealuminum tube bended completely without any joint,then pulling the al-tube inside the fins by mould, more tight

contact.

- With tubeexpansion system adopted, more tight contact between fins & tubes, heatexchange efficiency increased

40~60%

- Fin pitchescan be free engineered as per cooling request

- Supercleanness for R134a refrigerant

- Besides theevaporator main body without any brazing points; it highly reduces and avoidsthe risk of leakage.

Material:

- Al pipe (O.D8~10mm) X (Wallthickness0.7~1.0mm), brand: Gold-Dragon
- Fin: fin stock aluminum foil, thickness is 0.13~0.25mm
- Inlet & outlet tube: Al-Copper tube

Structure:

- Straight pipe type: needs the support bracket
- Inclined pipe type: reduces welding points, increases air flow; saves space; noneeds support bracket, which can further

save cost.

Coating quality: Chemical oxidization

- Cathode oxidization with oxidationfilm:12~30um
- Corrosion resistant: ≥96hrs
