ULTRA THIN HEAT PIPE AND ITS APPLICATION

Abstract

Thermal performance of heat pipe becomes worse rapidly when heat pipe is flattened in order to be mounted on electronic equipments. This is because maximum heat transfer rate and thermal resistance of heat pipe are strongly related to inner vapor and liquid flow space, so heat pipe does not work well when these space are narrowed. In order to overcome this issue, we have developed ultra thin heat pipe which has both high maximum heat transfer rate and thin thickness by optimizing inner structure. In this paper, we report development of ultra thin heat pipe and some applications of it.
