Abstract
A heatsink is used with a fluid flow generator that rotates about a central axis extending vertically. The heatsink includes a main body section having a top surface facing the fluid flow generator in a vertical direction, and fins that extend upward from the top surface so as to define a plurality of flow passages. The plurality of flow passages form a plurality of fluid paths, each of which has an inlet for the fluid discharged from the fluid flow generator to flow in, and an outlet for discharging to outside the fluid that has entered through the inlet. At least one of the plurality of fluid paths has a first branch section for branching from a first fluid path on downstream of the inlet, and a first joining section for joining a second fluid path having another inlet, on downstream of the first branch section.
