With the rapid increase in the heat output of desktop computer CPU, many desktop computer CPU radiators have inevitably chosen large-sized radiating fins and fans with high rotating speed and large air volume to enhance the heat dissipation effect. However, such a solution has brought about negative effects-noise pollution. Noise has seriously affected the operating environment and is harmful to human health. It is the strong wish of every computer user to reduce or reduce the noise of CPU radiator.

Taiwan sanju motors propose a phase change radiator scheme for desktop computer CPU chips, especially a phase change radiator for desktop computer CPU chips. It comprises a phase change heat transfer tube radiating fin, a base and a fastener, wherein the tube bottom of one or more copper series or aluminum series metal phase change heat transfer tubes is in good contact with the base and penetrates through the base. The utility model has the advantages that the utility model does not have a fan, and only relies on the power supply fan or the chassis fan to enhance the heat dissipation effect of the radiator.
