PROBLEM TO BE SOLVED: To provide a power supply device capable of evenly cooling a battery.SOLUTION: A power supply device 1 includes: a plurality of batteries 2; an accommodating body 4 which constitutes an accommodation chamber 13 for accommodating the battery 2 and has a plurality of intake portions 17A for taking air into the accommodating chamber on an upper side of the accommodating chamber; a housing 3 that stores the accommodating body in an inner space formed by a plurality of wall surfaces including a first transverse wall surface 31 opposed to the intake portion and a longitudinal wall surface 36 connected to the first transverse wall surface and extending to the accommodating body side; a blower 5 having a blowout portion 5a; and a diffusion part 66 for diffusing the air blown from the blower into the internal space. The diffusion part diffuses and guides the air blown out from the blowout portion into the internal space on the basis of a ratio of an opening area of the intake portion.SELECTED DRAWING: Figure 3
【課題】電池を均等に冷却することができる電源装置を提供すること。【解決手段】電源装置1は、複数の電池2と、電池2を収容する収容室13を構成し且つ収容室内に空気を取り入れる複数の取入部17Aを収容室上側に有する収容体4と、取入部と対向する第1横壁面31と、第1横壁面と接続し且つ収容体側へと延びる縦壁面36を含む複数の壁面により構成された内部空間に収容体を格納する筐体3と、吹き出し部5aを有する送風機5と、送風機から吹き出された空気を内部空間へ拡散する拡散部66を備え、拡散部は、吹き出し部から吹き出された空気を、取入部の開口面積の比に基づいて内部空間に拡散して導く。【選択図】図3
