Zusammenfassung:To provide a cooling device of a vehicle which can raise cooling performance of ATF in an ATF cooler.SOLUTION: A cooling device of a vehicle comprises: an ATF side drain pipe 50 for flowing drain water coming out from an air conditioner 20 to an ATF cooler 40; and a control device 60 which controls flow of the drain water to the ATF side drain pipe 50, wherein the control device 60 performs control to flow the drain water to the ATF side drain pipe 50 in a cooling operation of the air conditioner 20 and when temperature of a motor 31 is a predetermined value or higher. Thus, the ATF cooler 40 itself can be cooled by flowing the drain water coming out from the air conditioner 20 to the ATF cooler 40. Thus, cooling of the ATF can be supported by the drain water coming out from the air conditioner 20. As a result, ATF cooling performance in the ATF cooler 40 can be raised.SELECTED DRAWING: Figure 1 【課題】ATFクーラでのATFの冷却性能を高めることができる車両の冷却装置の提供。【解決手段】空調装置20から出てくる排水をATFクーラ40に流しかけるためのATF側排水管50と、ATF側排水管50への排水の流れを制御する制御装置60と、を有し、制御装置60が、空調装置20の冷房運転時であってモータ31の温度が所定値以上の場合に、排水をATF側排水管50に流すよう制御する。そのため、空調装置20から出てくる排水をATFクーラ40に流しかけることでATFクーラ40自体を冷やすことができる。そのため、空調装置20から出てくる排水でATFの冷却を補助できる。その結果、ATFクーラ40でのATF冷却性能を高めることができる。【選択図】 図1
