Title:
VAPOR CHAMBER HAVING HIGH HEAT ABSORPTION PROPERTIES AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/272492
Kind Code:
A1
Abstract:
A vapor chamber having high heat absorption properties, comprising a substrate layer. The vapor chamber further comprises a protective layer; the protective layer is adhered and solidified on the outer surface of the substrate layer, is dark in color, and is used for enhancing the oxidation resistance and heat conductivity of the vapor chamber. Further disclosed is a preparation method for the vapor chamber. The characteristics and advantages are that: a deep color protective layer is formed on the surface of the substrate layer of the vapor chamber by means of surface treatment, and thus the corrosion resistance, oxidation resistance, and heat conduction property of the vapor chamber can be effectively improved. The problems that existing products are not resistant to corrosion, and the appearance becomes poor due to corrosion after long-term use are solved. The vapor chamber further comprises a transition layer solidified between the substrate layer and the protective layer, the transition layer can be separately subjected to co-permeation with the substrate layer and the protective layer, the surface hardness of the vapor chamber is improved, the problem that copper and copper alloy vapor chambers are prone to deformation is solved, the substrate layer, the transition layer, and the protective layer which are subjected to co-permeation are completely fused into a whole, and the problem that the protective layer is easy to fall off is effectively solved.
