Common new-type electronic cooler are generally steel, aluminum, copper, copper-aluminum composite, stainless steel and so on. Among them, steel high pressure, good thermal function, strong and durable, but afraid of oxygen erosion; aluminum heat dissipation, decorative good, oxidation-resistant, but afraid of alkaline water corrosion, and not suitable for high-rise living conditions, because the water pressure resistance is small; copper corrosion resistance, beautiful shape, thermal conductivity is the best, the fastest heat, but the price is expensive.

In recent years, the new type of electronic radiator, with its excellent appearance and good heat dissipation performance, has gradually replaced the traditional radiator products. New radiator products not only bring home to warm and comfortable, or home art is an essential embellishment, become an indispensable part of modern life. How to judge the quality of electronic radiator, the following to introduce.

1, the surface of the electronic radiator should be free of shrinkage, corrosion, crack and other defects. 

2, flat plate electronic radiator metal fasteners, water-cooled radiator conductive plate should be protected by plating; The maximum allowable Surface roughness value for an electronic radiator is 3.2 m, the flatness of the radiator is not less than grade 9, and the surface of the radiator used in the wet tropical power semiconductor device should be protected, its resistance to salt spray, humidity and mould should meet the tropical semiconductor device standard.
