Advantages of copper-aluminum composite radiator:
Copper is also an inert metal from a chemical point of view. It has a certain anti-corrosion effect and is plastically diversified. Corrosion resistance, long service life, good thermal conductivity, high efficiency and energy saving. The service life is more than 30 years.
Defects of copper-aluminum composite radiator:
1 When welding, the shrinkage coefficient of weld filler and copper pipe does not differ, which may cause cracking of the weld. If water with sodium chloride (commonly known as “saltâ€) enters between copper and aluminum, it will show galvanic corrosion and leak.
2 The high cost of copper is unscrupulous. In the middle of the waterway, a manufacturer inserts a carbon steel pipe instead of a copper pipe to deceive the consumer. The ordinary surface cannot be seen.
3 When the copper-aluminum composite heat sink is heated, the heat shrinkage coefficient is not divergent, and the aluminum alloy and the copper tube are peeled off, so that the copper and the aluminum are filled with air, thereby forming an air isolation effect, which causes the heat efficiency of the radiator to be lost by 25%. Copper is prone to fouling, easy to infarction, and high cost. Http://ProductView.asp?ID=545&SortID=191
