Cast iron heat sink
The biggest advantage is corrosion-resistant. But the energy consumption is large and environmental pollution is serious with huge weight, poor appearance quality, low pressure bearing and the production technology is backward, there is sticky sand in the lumen, which does not meet the requirements of energy-saving, environmental protection, and cast iron extruded heat sink has been listed as the product which is phasing out in China.
Steel column heat sink
The appearance is pretty, can be curved, and it is welded by different pipes with a great deal of welding line and it is not easy to deal with the welding joint. At the same time, due to the curved shape, the wall thinning of the curved part is thin, which may bring a hidden danger. The column type heat transfers heat sink relying on their column outer wall, while the heat transfer area is small and the cooling effect is relatively poor.
Aluminum heat sink
Take the aluminum as the raw materials of aluminum heatsink, whose weight is light and heat dissipation effect is good. Due to the characteristics of the aluminum itself, which is not easy for manufacturing, modeling is not easy to diversify and is not easy to meet the high demands of the home improvement, in addition, there are certain problems in the welding process; aluminum alkali corrosion is serious and due to the heating system boilers and pipes are mostly made of steel, in order to protect system, the water quality is generally alkaline, and aluminum radiators must be done within the anti-corrosion. In addition, aluminum and other metals prone to electrochemical corrosion, it cannot be mixed with steel products, copper products, and we have to strictly control the content of copper and iron in water.
Steel panel heat sink
Take the steel as its raw materials, and it is manufactured by the composition of walking water part and convection films. Walking water in part by two roll forming block plate welded together by cooling area, sheet metal without deformation, easy to weld molding. Clean production technology, environmental protection, beautiful and generous product appearance, good decorative effect, high pressure bearing, excellent thermal effects, which can effectively save energy, in line with the energy-saving, environmental protection requirements. But steel heat sink must be maintained with the full water in the non-heating period, while the domestic heating systems in some places cannot be in the full water maintenance.
