Title:
VAPOR CHAMBER AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/021719
Kind Code:
A1
Abstract:
The present application discloses a vapor chamber and an electronic device. The vapor chamber comprises a first cover plate and a second cover plate, the second cover plate is snap-fitted to the first cover plate to form a sealed cavity, at least one composite capillary structure is arranged in the sealed cavity at intervals, and steam channels are formed on two sides of each composite capillary structure. The composite capillary structure comprises a porous capillary structure and a channel capillary structure which are both filled with a cooling medium. The steam channels and the composite capillary structure are of a left-right parallel structure, and the overall height of the vapor chamber can be decreased by decreasing the height of the composite capillary structure, so as to achieve lightening and thinning. Meanwhile, by adoption of composite design of the porous capillary structure and the channel capillary structure, the high capillary force action of the porous capillary structure and the high permeability of the channel capillary structure are utilized, so that the composite capillary structure can decrease the flow resistance of working medium transmission and promote rapid transmission of a working medium, thereby realizing reduction of the overall thickness of the vapor chamber without attenuation of performance, and meeting the lightening and thinning requirements for an electronic device.
