To provide a cooling structure for a rotary electric machine comprising supply pipes supplying a coolant an upper side of the rotary electric machine, capable of improving cooling performance of the rotary electric machine by improving supply stability of the coolant.SOLUTION: A cooling structure 80 for a rotary electric machine 20 comprises a first supply pipe 32 and a second supply pipe 34 which are disposed in parallel at an upper side of the rotary electric machine 20 and each of which includes a discharge hole 76 from which a coolant is discharged towards the rotary electric machine 20. A direction of a coolant flowing in the first supply pipe 32 and a direction of a coolant flowing in the second supply pipe 34 are opposite to each other.SELECTED DRAWING: Figure 2
【課題】回転電機の上方から冷媒を供給する供給管を備える回転電機の冷却構造において、冷媒の供給安定性を向上でき、回転電機の冷却性能を向上できる回転電機の冷却構造を提供することである。【解決手段】回転電機20の冷却構造80は、回転電機20の上方に並列して配置され、回転電機20に向けて冷媒を吐出する吐出孔76を有する第1供給管32及び第2供給管34を備え、第1供給管32内を流れる冷媒の向きと、第2供給管34内を流れる冷媒の向きが互いに対向している。【選択図】図2
