Experimental study of Thermal performance on heat pipe radiator

Abstract The heat pipe radiator has become an effective way to solve the heat dissipation problem of electronic components due to its advantages of good reliability and high-heat dissipation efficiency. So it is necessary to explore the thermal performance of heat pipe radiators.In this paper,gravity radiators with two,four,and six heat pipes are used as the research object.The thermal performance of the three heat pipe radiators with different numbers of heat pipes is compared and analyzed through experiments.It mainly includes the influence of a different number of heat pipes on the heat dissipation power, thermal resistance,temperature uniformity, start-up time and other parameters of the radiator.Research shows that the number of heat pipes is one of the main factors affecting the thermal performance of a radiator. The more heat pipes,the better the thermal performance.
