Abstract

The embodiment of the invention provides a vapor chamber, a vapor chamber manufacturing method and electronic equipment. The vapor chamber forms a closed accommodating cavity through bonding connection between a first shell and a second shell, a capillary structure is located in the accommodating cavity, and the capillary structure is located in the accommodating cavity; moreover, the capillary structure is arranged in the second shell, and the face, facing the second shell, of the capillary structure is fixed to the second shell, so the vapor chamber has a good heat dissipation function; meanwhile, the manufacturing cost generated in the production process of the vapor chamber can be reduced, and the phenomenon of poor products can be reduced to a large extent.

Description

technical field [0001] The present application relates to the technical field of heat dissipation, and in particular to a vapor chamber, a method for manufacturing a vapor chamber, and electronic equipment. Background technique [0002] With the miniaturization of terminal electronic equipment (such as mobile phones, computers, etc.), the integration level and assembly density of electronic components continue to increase. The sharp increase, so the terminal electronic equipment's demand for chip heat dissipation increases accordingly. [0003] At present, more and more electronic devices use vapor chambers as heat dissipation elements. Vapor chambers are mainly composed of shells, capillary structures, and working fluids. Among them, the shells include upper shells and lower shells, and upper shells and lower shells. A closed housing cavity is formed by brazing between the shells, and a plurality of capillary structures at intervals are arranged in the housing cavity. One ...
