PROBLEM TO BE SOLVED: To effectively cool an on-vehicle charger with a simple structure.SOLUTION: A vehicle 10 includes a power control unit PCU 5 which has a cooling mechanism and does not operate when a battery 3 is charged by an on-vehicle charger 2. The on-vehicle charger 2 includes: a suction duct 21 in which one end communicates with the interior of the on-vehicle charger 2 and a suction port 21a is provided at the other end; and a cooling fan 22 which causes air to be suctioned from the suction duct 21 toward the interior of the on-vehicle charger 2. The suction port 21a of the suction duct 21 opens near a housing 520 of an inverter 52 of the PCU 5 which is cooled by the cooling mechanism.SELECTED DRAWING: Figure 1
【課題】簡便な構成で効果的に車載充電器を冷却する。【解決手段】車両10は、冷却機構を有するとともに車載充電器2によるバッテリ3の充電時には動作しないPCU5を備える。車載充電器2は、一端が当該車載充電器2の内部に連通されるとともに他端に吸気口21aを有する吸込ダクト21と、当該車載充電器2の内部に向けて吸込ダクト21から空気を吸入させる冷却ファン22とを備える。吸込ダクト21の吸気口21aが、PCU5のインバータ52のうち冷却機構に冷却される筐体520の近傍に開口している。【選択図】図1
