Why can aluminum alloy be used as heat sink material?
1. The heat dissipation performance of aluminum alloy is very good. It is much higher than radiators of other materials, so the heat dissipation capacity of aluminum alloy radiators is much higher than that of other materials.
2. The chemical activity of aluminum in the alloy is very active, and it is easy to quickly react with oxygen in the air to form a dense aluminum oxide protective film with a thickness of about 1 μm. It bonds very strongly to the substrate, passivates the surface of the coating and prevents itself from continual oxidation. Therefore, the aluminum alloy itself is not afraid of oxygen, and there is no oxygen corrosion.
The principle of internal anti-corrosion of the radiator: the internal anti-corrosion treatment of the radiator is to coat a layer of organic paint with good adhesion and corrosion resistance on the inner surface of the radiator to isolate water; steel and aluminum materials have anti-corrosion effects. There is a dense aluminum oxide protective film on the surface of the aluminum alloy, so it is difficult to adhere to the anti-corrosion layer. Even if it is used, the anti-corrosion coating on the surface of the aluminum alloy is easy to peel off under the washing of water inside the radiator.
3. With its superior corrosion resistance, wide applicability, better thermal price ratio, higher value retention rate and beautiful appearance, aluminum alloy radiators will become the leader of new radiators for a long time in the future By. The market prospect is also very broad. With the continuous development and promotion of aluminum alloy radiators, it will play a greater role in the development of the industry.
