Summary:To provide a water jacket capable of effectively cooling a heat generating component by appropriately controlling the flow of a refrigerant.SOLUTION: A water jacket WJ for cooling an inverter module IM includes a base 1 having a plate shape. The base 1 includes: a refrigerant supply passage 11 having a refrigerant inflow part 11a into which the refrigerant flows; a refrigerant discharge passage 12 having a refrigerant outflow part 12a from which the refrigerant flows out; and a chamber 13 which communicates with the refrigerant supply passage 11 and the refrigerant discharge passage 12. The chamber 13 includes: a plurality of columnar fins 133 which are erected from a first surface 131 on the side where the inverter module IM is arranged and intersect with the flow direction B of the refrigerant; and a plurality of wing-like fins 134 arranged on the second surface 132 side opposed to the first surface 131 and inclined or curved from the second surface 132 toward the first surface 131 as it goes from the upstream to the downstream in the flow direction B of the refrigerant.SELECTED DRAWING: Figure 5 【課題】冷媒の流動を適切に制御して発熱部品を効果的に冷却可能なウォータージャケットを提供する。【解決手段】インバータモジュールＩＭを冷却するウォータージャケットＷＪは、板形状を有する基台１を備える。基台１は、冷媒が流入する冷媒流入部１１ａを有する冷媒供給路１１と、冷媒が流出する冷媒流出部１２ａを有する冷媒排出路１２と、冷媒供給路１１と冷媒排出路１２とに連通するチャンバ１３と、を備える。チャンバ１３には、インバータモジュールＩＭが配置される側の第１面１３１から立設され、冷媒の流れ方向Ｂに対し交差する複数の柱状フィン１３３と、第１面１３１に対向する第２面１３２側に配置され、冷媒の流れ方向Ｂにおいて上流から下流に向かうに従って第２面１３２から第１面１３１に向かって傾斜又は湾曲する複数の翼状フィン１３４と、を備える。【選択図】図５
