The invention provides a chassis member, which may be made of a cast material such as magnesium, aluminum, or plastic, for mechanically supporting a heat producing electronic device in which the chassis member has a base and a cavity integral to the chassis member. In a preferred embodiment, the cavity is in the form of a channel that is created by boring. The channel may be evacuated and has an evaporator section, a condenser section, and a working fluid confined therein by a seal. The channel receives heat from an electronic device in an evaporator sec...


1. In a portable computer, a chassis member for supporting an electronic device that produces heat, said chassis member comprising:a cavity integral to said chassis member, such that said chassis member was formed by molding a structural material and such that structural material surrounding said cavity and forming side walls of said cavity is homogeneous to said chassis member in that said structural material was formed by molding in the some manufacturing step as said chassis member was formed by said molding; a seal, sealing said cavity; a working flu...
