Brazed Radiator is used in the winter, especially in old areas, where there is no place to install heating, facing cold, they can only choose Brazed Radiator to heat, but the home Brazed Radiator has a lot of material, such as copper and aluminum composite Brazed Radiator, Steel Brazed Radiator, etc., to choose what material is better?
First, copper and aluminum composite Brazed Radiator: the role of copper anti-corrosion, in the Brazed Radiator's inner tube to adopt the copper, the internal use of good thermal conductivity of the aluminum wing, seemingly perfect connection, may have fatal Disadvantages: copper Brazed Radiator inner wall, Generally very thin, but the heating water quality is poor, there are very more hard impurities, coupled with their own very soft copper, it is easy to wear, often copper and aluminum composite tube burst wall of the accident produced. Coupled with the heat shrinkage of copper and aluminum is different, with a long time will occur "core" signs, heat dissipation rate will be significantly reduced.
Second, the steel Brazed Radiator: Steel Brazed Radiator product stability and advanced technology, while the steel Brazed Radiator because of its material itself with the characteristics of macromolecules for the penetration of water molecules, so the steel Brazed Radiator heating room is not Will feel clearly dry, so it is very suitable for human science, which is any other material Brazed Radiator are not reach. Although the steel Brazed Radiator price is indeed cheaper than steel, or can save the steel Brazed Radiator corrosion resistance heat dissipation.
Third, the stainless steel aluminum composite Brazed Radiator: copper and aluminum composite Brazed Radiator on the upgrade, stainless steel is not only anti-corrosion, and solid, but the stainless steel welding skills than steel Brazed Radiator welding mature, so choose a large brand manufacturers can, small Brand caution
Fourth, the aluminum alloy Brazed Radiator: is characterized by pressure resistance, corrosion resistance, the use of steel heating aluminum alloy fins, aluminum Brazed Radiator is absolutely can not be used in the heating system. But for the boiler heating, boiler aluminum alloy Brazed Radiator, small tube, heat is large, since the heating is very good energy-saving choice.
Brazed Radiator is usually a heat sink for high-power electronic components, no external power supply, natural cooling, most are made of aluminum alloy profiles, according to the size of the components cut into the required size, such as high-power switch or Transistor heat sink. Of course, special circumstances, ultra-high-power electronic components also have a cooling fan, such as switching power supply switch tube must be installed cooling fan.
Brazed Radiator surface quality generally meet the following six requirements:
1, the integration of the surface of the radiator should be no shrinkage, obvious cracks, gaps and other issues;
2, flat-shaped Brazed Radiator metal fasteners (pressure plate, gland, disc spring), water-cooled radiator conductive film should be coated with protection;
3, the heat dissipation table surface roughness Ra maximum allowable value of 3.2m;
4, the installation of electronic heat sink heat dissipation body of the final forming flatness, to reach more than 8;
5, Brazed Radiator (including heatsinks, fasteners and insulators) for wet and cold power semiconductor devices, the surface should be protected, its resistance to moisture, salt spray and resistance to mold should be consistent with the corresponding tropical power semiconductors Device standard.
