Title:
HEAT DISSIPATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/045429
Kind Code:
A1
Abstract:
The present application discloses a heat dissipation device. The heat dissipation device comprises: a seat assembly, a liquid inlet cavity being disposed inside the seat assembly, and the liquid inlet cavity being configured to accommodate a refrigerant; a guide toothed sheet assembly, disposed in the liquid inlet cavity; and a heat dissipation toothed sheet, disposed on the seat assembly and extending in a vertical direction, a passage being provided in the heat dissipation toothed sheet, the passage having a top end and a bottom end, and the bottom end of the passage being in communication with the liquid inlet cavity. The seat assembly is configured such that when a position where the seat assembly is attached to a chip is heated, heat is transferred to the liquid inlet cavity via the seat assembly, so that the refrigerant in the liquid inlet cavity is boiled and vaporized to form a gaseous refrigerant. The passage is configured such that the gaseous refrigerant enters the top end through the passage to condense to form a liquid refrigerant, so that the liquid refrigerant can flow back to the liquid inlet cavity through the passage.
