| Zusammenfassung: | To provide heat sink having high and stabilized radiation performance, even when liquid flows from both one end side and the other end side of a duct.SOLUTION: A heat sink 1A includes a base 10A in contact with an electrical heating element, multiple fins 20A projecting from one face of the base 10A, and forming a duct 200 therebetween, and a wall 30A placed in the duct 200 perpendicularly to one face and projecting from the one face to the height of the multiple fins 20A or more, and flowing the liquid, flowing through the duct 200, to a direction perpendicular to the one face.SELECTED DRAWING: Figure 1
【課題】流路の一端側、他端側の両方から流体が流れた場合でも、放熱性能が高く、その放熱性能が安定したヒートシンクを提供する。【解決手段】ヒートシンク１Ａは、発熱体と接触するベース１０Ａと、ベース１０Ａの一方の面から突出し、その間に流体を流す流路２００を形成する複数のフィン２０Ａと、流路２００内に配置され、一方の面に垂直かつ一方の面から複数のフィン２０Ａ以上の高さまで突出して流路２００を流れる流体を一方の面に対して垂直な方向へ流す壁３０Ａと、を備える。【選択図】図１ |
