PROBLEM TO BE SOLVED: To cool a battery in a balanced manner.SOLUTION: A power supply device 1 includes: a plurality of batteries 2; a housing 3 for storing a battery in an internal space surrounded by a plurality of wall surfaces including a first transverse wall surface 31 provided on a first side of the batteries, a first longitudinal wall surface 36 extending from the first transverse wall surface to the opposite side to the first side, a second transverse wall surface 35 provided opposed to the first side of the batteries opposed to the first transverse wall surface, and a second longitudinal wall surface opposed to the first longitudinal wall surface; and a blower 5 having a blowout portion 5a. An air introduction passage 50 including a first region 51 located on the side of the first longitudinal wall surface from the center of the blowout part and a second region 52 located on the second longitudinal wall surface side from the center of the blowout part between the first transverse wall surface and the battery for introducing the air blown out from the blowout portion into the battery is constituted. The air introduction passage has an enlarged portion 53 in which the distance d between the first transverse wall surface and the battery increases from the second region toward the first region. The blowout portion is disposed on the second longitudinal wall surface side from a position where the separation distance is the maximum between the battery and the second transverse wall surface.SELECTED DRAWING: Figure 3
【課題】電池をバランスよく冷却すること。【解決手段】電源装置1は、複数の電池2と、電池の第1の側に設けられた第1横壁面31と、第1横壁面から第1の側と反対側へと延びる第1縦壁面36と、電池の第1の側と反対側に設けられ第1横壁面と対向する第2横壁面35と、第1縦壁面と対向する第2縦壁面を含む複数の壁面に囲まれる内部空間に電池を格納する筐体3と、吹き出し部5aを有する送風機5とを備え、第1横壁面と電池の間に、吹き出し部の中心より第1縦壁面側に位置する第1領域51と吹き出し部の中心より第2縦壁面側に位置する第2領域52を含み且つ吹き出し部から吹き出された空気を電池に導入する空気導入通路50が構成され、空気導入通路は第2領域から第1領域に向けて第1横壁面と電池の離間距離dが広がる拡大部53を有し、吹き出し部は電池と第2横壁面との間であって離間距離が最大となる位置より第2縦壁面側に配置されている。【選択図】図3
