This article utilizes the experimental method to investigate the thermal performance of heat sinks with one and two pairs ofembedded heat pipes. A heat sink with embedded heat pipes transfers the total heat capacity from the heat source to both thebase plate and heat pipes, and then disperses heat into the surrounding air via the forced convection. The heat transferencefrom base plate to fins can be conducted through the examined results of the heat sink with and without the function of heatpipes. The heat capacity from heat pipes to fins is equal to the total heat minus the heat from base plate to fins. Therefore, theheat carried by embedded heat pipes can be found using the thermal resistance analytical approach stated in this article. Theresults show that two and four heat pipes embedded in the base plate carry 36% and 48% of the total dissipated heatrespectively; in addition, when the total heating power of the heat sink with two embedded heat pipes is 140W, the totalthermal resistance reaches its minimum value of 0.27ºC/W, while for the heat sink with four embedded heat pipes, when thetotal heating power is between 40W and 240W, the total thermal resistance is 0.24ºC/W, meaning that the thermalperformance is better than that of heat sink with two embedded heat pipes |
