WIPO Patent Application WO/2023/189070
Kind Code:
A1
Abstract:
Provided is a heat sink that can be used to prevent dryout even when the operating ambient temperature is lower than the melting point of a working fluid, without compromising heat transport characteristics. This heat sink comprises: a heat transport member having a heat-receiving part thermally connected to a heat-emitting element; and a first heat-dissipating fin group comprising a plurality of first heat-dissipating fins and thermally connected at a heat-dissipating part of the heat transport member, wherein the heat transport member has an internal space which is connected from the heat-receiving part to the heat-dissipating part and which has a working fluid sealed therein, and a heat transfer member is thermally connected to a heat-insulating part of the heat transport member located between the heat-receiving part and the heat-dissipating part.
