Title:
HEAT SINK
Document Type and Number:
WIPO Patent Application WO/2024/024712
Kind Code:
A1
Abstract:
Provided is a heat sink in which the thermal resistance when heat is transmitted from a heat-generating body to a heat-receiving part of a heat pipe is reduced, thereby making it possible to exhibit exceptional cooling characteristics even with respect to a heat-generating body having a high calorific value. A heat sink comprising: a heat pipe that has a heat-receiving part, which is thermally connected to a heat-generating body; and a heat exchanger that is thermally connected to a heat-releasing part of the heat pipe. The heat pipe has an internal space in which a working fluid is sealed, the internal space allowing communication from the heat-receiving part to the heat-releasing part. The portion of the heat-receiving part that faces the heat-generating body is a flat part that is flat along the extension direction of the heat-generating body. The flat part is directly in contact with the heat-generating body.
