The basic production process of heat sink
Heat sink is a kind of to electrical appliances used hot electron component cooling devices, much by aluminum alloy, brass or bronze plate, plate, sheet, such as more heat sinks commonly in use in electronic components and heat sink interface is coated with a layer of thermal conductive silicone, the components of heat conduction more effectively to the radiator, then through radiator sends out into the surrounding air. In terms of heat sink material, the thermal conductivity of each material is different, according to the thermal conductivity from high to low, respectively silver, copper, aluminum, steel.
The heat sink plays an important role in the composition of the heat sink. In addition to the active heat dissipation of the fan, the evaluation of a heat sink depends largely on the heat absorption ability and heat conduction ability of the heat sink itself.
