ELECTRICAL APPARATUS WITH COOLANT PASSAGE

PROBLEM TO BE SOLVED: To provide an electrical apparatus with a coolant passage capable of suppressing deviation in the flow distribution of coolant at a barrier wall mounting an electrical component, while suppressing occurrence of hot spots, and capable of being made compact.SOLUTION: An electrical apparatus with a coolant passage includes: a housing 1 having first and second spaces via a barrier wall; an electrical component mounted on the barrier wall in the first space; and a plurality of inflow side diffusion members 8 and outflow side diffusion members 10 on a flat plate provided, respectively, in a coolant inflow passage 7 into which coolant flows in from the outside of the housing 1 in the second space, and a coolant outflow passage 9 facing the coolant inflow passage 7 and outflowing the coolant to the outside of the housing 1, while fixing the end faces to the barrier wall, and diffusing the coolant flow.SELECTED DRAWING: Figure 3 【課題】電気部品が搭載された隔壁での冷媒の流量分布の偏りを抑制でき、ホットスポットの発生を抑制することができるとともに、小型化が可能な冷媒流路付き電気機器を提供する。【解決手段】この冷媒流路付き電気機器は、隔壁を介して第１の空間及び第２の空間を有する筐体１と、前記第１の空間内で隔壁に搭載された電気部品と、前記第２の空間内で筐体１の外部からの冷媒が流入する冷媒流入通路７、及びこの冷媒流入通路７と対向し筐体１の外部に冷媒を流出する冷媒流出通路９に、それぞれ端面が隔壁に固定して設けられ、冷媒の流れを拡散する、複数の平板上の流入側拡散部材８及び流出側拡散部材１０と、を備えている。【選択図】図３
