Abstract

A compact vapor chamber configured to thermally conduct heat of an electronic heat-generating element includes a flat sealed casing; a wick structure arranged on inner walls of the flat sealed casing; a working fluid filled inside the flat sealed casing; and an evaporating section formed on a portion of the vapor chamber. An outer surface of the flat sealed casing on the evaporating section has a recess for covering the electronic heat-generating element. The recess is brought into thermal contact with the electronic heat-generating element. With this arrangement, when the compact vapor chamber is brought into thermal contact the electronic heat-generating element for heat dissipation, the distance of the electronic heat-generating element protruding from the compact vapor chamber is reduced, thereby facilitating the compact design of an electronic product. Further, the present invention provides a heat-dissipating module having such a compact vapor chamber.
