Title:
HEAT SINK FOR SELF-OSCILLATING HEAT PIPE
Document Type and Number:
WIPO Patent Application WO/2020/158324
Kind Code:
A1
Abstract:
In order to solve the problem wherein cooling performance of a heat sink for self-oscillating heat pipe is best in the proximity of the center of the heat pipe in the longitudinal direction, and deteriorates towards the ends, this heat sink for self-oscillating heat pipe is constituted to comprise: a self-oscillating heat pipe having a structure wherein multi-holed flat pipes are connected in a rectangular wave shape in the thickness direction to form a wave shape, and said multi-holed flat pipes have an operating fluid sealed therein, thereby alternately positioning the heat-receiving portion and heat-dissipating portions; a heat-receiving member which is joined to the heat-receiving portion; and a heating element which is positioned on the surface opposite the joining surface of the heat-receiving member which joins with the heat-receiving member. The heat sink for self-oscillating heat pipe has the characteristic wherein by changing at least one of the configuration of the heat-receiving portion, the configuration of the heat-dissipating portion, the configuration of the heat-receiving member, or the configuration of the heating element, the distribution of heat input to the self-oscillating heat pipe via the heat-receiving portion becomes smaller from the proximity of the center of the multi-holed flat pipe towards the ends of said multi-holed flat pipe.
