Vapor chamber and cooling device having the same

Abstract

A vapor chamber is provided to include shell, capillary tissue, working fluid, heat-absorbing section and heat-releasing section. A hollow chamber is formed in the shell. The capillary tissue is arranged and accommodated in the hollow chamber. The working fluid is injected into and filled in the hollow chamber. Two corresponding surfaces of the shell at the heat-releasing section are respectively a non-planar shape. Because the two corresponding surfaces of the shell at the heat-releasing section are respectively a non-planar shape, the structure strength of the vapor chamber is higher and the anti-deforming ability is superior, thereby the using life of the vapor chamber being prolonged. In addition, the vapor chamber can be combined with cooling fins to become a cooling device. Since the two corresponding surfaces of the shell at the heat-releasing section are respectively designed as a non-planar shape, the vapor chamber and the cooling fins have larger contacting surfaces, making the heat-transferring effectiveness thereby enhanced significantly.
