Tube Type Black Anodized Auto Radiator

The tube type radiator is composed of cooling tubes and radiators. The  tube type radiator cross-sections of the cooling tubes are mostly oblate. The purpose is to reduce the resistance of the air, provide sufficient heat transfer area, and complete the heat transfer between the tube type radiator , coolant and air. exchange. The pipe-band radiator is welded and arranged in alternating phases. The two parts are corrugated heat-sinks and cooling pipes. The heat dissipation capacity of the tube-strip radiator is stronger, and the heat dissipation area is about 12% larger.

Anodizing enhances the corrosion resistance of the aluminum surface, extending the service life of your auto radiators. The black oxide film is not only functional, but also improves the aesthetic appearance of the radiator product. Of course, auto radiators anodizing can be customized in a variety of colors for you to choose.

1.Wear resistance - the surface of ordinary aluminum alloy has a typical "natural aluminum" color, the microlayer is easily oxidized, the hardness of aluminum is soft, and the wear resistance is low. After black anodization, the surface is treated with spot oxidation, and hard AI2Q3 is deposited in the formed oxide layer to make the auto radiators more wear-resistant.

2. Chemical resistance - Aluminum easily reacts with acids and bases, and even fingerprints can easily oxidize the aluminum itself. The anodized black anodized radiators is not prone to chemical reactions with acids and alkalis under harsh conditions, greatly ensuring durability.

3. Cooling efficiency - the most important parameter is the extremely low untreated surface radiation capability. The radiation rate of natural aluminum is only 0.05, which is too low. After anodizing the radiator, the emissivity can be increased to 0.80, which helps heat transfer and promotes heat dissipation of auto radiators.
