Thermal Analysis of Vapor Chamber Used for LED Cooling

摘要：

Vapor chamber (VC), as a new type of heat pipe technology, with high thermal conductivity and good temperature uniformity, becomes one of the most promising technologies to solve the high-power LED thermal problems. In this paper, we study on the heat transfer performance of VC thermal module by using a combination of experimental and numerical simulation methods, and the influence of heat source layout (centralized and distributed layout) has been discussed to provide theoretical guidance for the arrangement of the LED chips. The results show that VC module is an effective cooling method for high-power LED.
