Experimental investigation on thermal performance of metal foam capillary wick heat pipe
摘要
Abstract
In order to solve the thermal management problem of high power electronic devices, a novel heat pipe(NHP) was designed with ultra-light porous copper foam metal as capillary wick. The effect of heat fluxq and inclination angel of heat pipeθon thermal performance of the NHP was studied using acetone as the working fluid. The differences of thermal performance among NHP, convention heat pipe (CHP) and heat sink (without heat pipe) were compared. The results show that the NHP has not only good heat transfer capability, but also wonderful temperature uniformity. Whenθ=0° and q=117.2 W/cm2, the largest temperature difference between the measuring point is less than 7.0℃, and the center temperature of the heating surface is just 56.2℃. Inclination angle of heat pipe has certain effect on thermal performance of the NHP, and the thermal performance ofθ=0° is better than that ofθ=180°.关键词
