Heat pipe

A laptop computer heat pipe system. A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. [1]At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and …
