PROBLEM TO BE SOLVED: To suitably adjust a temperature of an on-vehicle charger and a battery in a simple structure.SOLUTION: An on-vehicle electrical component temperature adjustment device 1 comprises: a cooling fan 4; air duct 5 through which cooling air from the cooling fan 4 is blown, and which has two branching paths 51 on a downstream side in an air blowing direction, and two housing chambers 52 on a further downstream side; a first switching valve 61 that can open/close any one of the two branching paths 51; a second switching valve 62 that can open/close a communication hole 52b between two housing chambers 52; and an ECU 10. An on-vehicle charger 2 is housed into a first housing chamber 521 of two housing chambers 52 and a battery 3 is housed into a second housing chamber 522. The ECU 10 makes the first switching valve 61 close a first branching path 511 during traveling of the vehicle and makes the second switching valve 62 close the communication hole 52b, and during charging in the case when a temperature Tof the battery 3 is lower than a first temperature threshold value α, makes the first switching valve 61 close a second branching path 512 and makes the second switching valve 62 open the communication hole 52b.SELECTED DRAWING: Figure 4
【課題】簡便な構造で車載充電器及びバッテリの温度を好適に調節する。【解決手段】車載電装品温調装置1は、冷却ファン4と、冷却ファン4の冷却風が送風され、その送風方向下流側の2つの分岐路51と、さらに下流側の2つの収容室52とを有する送風ダクト5と、2つの分岐路51のいずれか一方を開閉可能な第一切替弁61と、2つの収容室52間の連通孔52bを開閉可能な第二切替弁62と、ECU10とを備える。2つの収容室52のうち第一収容室521内に車載充電器2が収容され、第二収容室522内にバッテリ3が収容される。ECU10は、車両走行中には第一切替弁61により第一分岐路511を閉塞させて第二切替弁62により連通孔52bを閉塞させ、バッテリ3の温度TBが第一温度閾値α1より低い場合の充電中には、第一切替弁61により第二分岐路512を閉塞させて第二切替弁62により連通孔52bを開放させる。【選択図】図4
