Abstract

A heat pipe exchanger system for cooling a hinged computing device. The hinged computing device includes a first hinged member having a first edge and second hinged member having a second edge. The first and second hinged members are rotatably attached along the first and second edges. A heat exchange sheath is mounted substantially parallel to the first and second edges and defines a first opening and a second opening. A first heat pipe is thermally coupled to the integrated circuit and has a portion disposed within the first opening. A second heat pipe is coupled to the display housing and has a portion disposed within the second opening. Alternately, the first heat pipe is coupled to the first hinged member and has a first portion substantially parallel to the first edge and the second edge. In this case, the second heat pipe is coupled to the second hinged member and has a first portion substantially perpendicular to the first heat pipe as well as a second portion conformally engaging the first heat pipe.
