Abstract

A heat-dissipating module having a loop-type vapor chamber includes a heat-dissipating body, a loop-type vapor chamber, and a heat-conducting medium. The loop-type vapor chamber is completely covered by the heat-dissipating body. The loop-type vapor chamber includes a loop body, a wick structure and a supporting structure. The loop body includes a bottom plate and a cover plate. A vacuum chamber is formed between the bottom plate and the cover plate. The wick structure is arranged on inner surfaces of the cover plate and the bottom plate. The supporting structure abuts the wick structure toward the cover plate and the bottom plate. The loop-type vapor chamber is tightly connected to the heat-dissipating body via the heat-conducting medium.
