Title:
HEAT SINK
Document Type and Number:
WIPO Patent Application WO/2024/024763
Kind Code:
A1
Abstract:
Provided is a heat sink with which it is possible to reduce pressure loss occurring when cooling air flows along a heat-dissipating fin while ensuring exceptional heat exchange performance in the heat-dissipating fin. A heat sink having: a heat-receiving part that is thermally connected to a heat-generating body; a flat first heat-dissipating fin that is thermally connected to the heat-receiving part, the first heat-dissipating fin having a first main surface; and a flat second heat-dissipating fin that is thermally connected to the heat-receiving part, the second heat-dissipating fin having a second main surface, and the area of the second main surface being less than the area of the first main surface. The second heat-dissipating fin is disposed between a plurality of the first heat-dissipating fins, specifically at a position such that the second main surface overlaps the first main surface in plan view.
