To cool heated equipment suitably while maintaining quietness in a vehicle at the time of traffic congestion.SOLUTION: An in-vehicle equipment cooling device includes a cooling fan that cools a high voltage battery mounted on a vehicle, and a battery. The battery determines whether a traveling road of the vehicle is congested or not, and calculates a first cooling amount R1 depending on the heated amount of the high voltage battery and a second cooling amount R2 depending on a noise value in the vehicle. When it is determined that a traveling road is congested and the first cooling amount R1 is smaller than the second cooling amount R2, the battery operates the cooling fan so as to restrict a decreasing rate of the cooling amount to be lower than an increasing rate and to cool the high voltage battery with a cooling amount larger than the first cooling amount R1 and equal to or lower than the second cooling amount R2.SELECTED DRAWING: Figure 3

    【課題】渋滞時において、車内の静粛性を保ちつつ発熱機器を好適に冷却する。【解決手段】車載機器冷却装置は、車両に搭載された高電圧バッテリを冷却する冷却ファンと、バッテリとを備える。バッテリは、車両の走行路が渋滞しているか否かを判定し、高電圧バッテリの発熱量に応じた第1冷却量R1、及び、車内の騒音値に応じた第2冷却量R2を算出する。また、バッテリは、走行路が渋滞していると判定されたときであって、第1冷却量R1が第2冷却量R2よりも小さい場合に、冷却量の下降レートを上昇レートよりも低く制限しつつ、第1冷却量R1よりも大きくかつ第2冷却量R2以下となる冷却量で高電圧バッテリを冷却するように、冷却ファンを動作させる。【選択図】図3
