Abstract: As the working frequency and the integration degree of electronic devices keep increasing, their heat productivity
increases rapidly. The traditional radiator is hard to cool the device as required, and it will cause bad influence on the steady
of the device. Based on the analysis of heat tube working principle, this paper built the heat transfer model of heat tube radiators and analyzed the differences between traditional radiators and heat tube radiators in heat-sinking capability. The
advantages of heat tube radiators in heat-sinking capability, setting up, layout and operating are educed.
