Ultra Thin Heat Pipe and Its Application

We have developed ultra thin heat pipe which can be applied to thinner and lighter electronic equipments. In this study, we focused on optimizing vapor and liquid flow pressure drop in the heat pipe. As a result, we have succeeded in developing 1 mm thickness heat pipe which had maximum heat transfer rate of 22.1W. And also, we have developed ultra thin heat pipe which had both high maximum heat transfer rate and thin thickness by optimizing inner structure. In this paper, we reported development of ultra thin heat pipe and some applications of it.
