But silver is expensive, copper is bulky, and aluminum is light, both in heat and weight, so aluminum is widely used as a cooling material for electronic parts. You can choose the alloy material with high content of "copper" or "silver", so that the heat conduction effect will be greatly enhanced.

It is best to choose heatsink with heat pipes. Heat pipe has high thermal conductivity, good isotherm, heat transfer area on both sides of heat and cold can be arbitrarily changed, long-distance heat transfer, temperature control and other advantages. Heat pipe mainly use the evaporation and condensation of working fluid to transfer heat. (the working fluid of heat pipe covers from helium and nitrogen applied at low temperature to liquid metals such as sodium and potassium applied at high temperature. The common working fluids of heat pipe are ammonia, water, carbinol and so on. Compared with traditional metal heatsinks, heat pipe heatsinks have the advantages of low noise and high efficiency, and the price of heat pipe heatsinks is getting cheaper with the continuous mature and large-scale production and application of the technology.
