Cooling fins

　　Cooling fins are radiation devices of electronic components for electric appliances. Copper and aluminum alloys are made into plates, flakes and splintery. Computers, TV, power amplifiers, power electronics, broadcast communication, smart grid, rail traffic, new energy, aerospace, lasers and medical facilities will use cooling fins. General cooling fins should smear a layer of heat conduction silicone grease on electronics and cooling fin surface, thus heat released by components will be effectively transferred to cooling fins and emit to ambient air through cooling fins.
