To provide a vehicle cooling cycle which enables improvement of cooling performance of a transmission and a rotary electric machine with a simple structure when a vehicle travels by driving of the rotary electric machine.SOLUTION: A vehicle cooling cycle 15 includes a first cooling cycle 16, a second cooling cycle 17, a heat exchanger 26, and a first electric pump 25. The first cooling cycle circulates a first refrigerant with a first mechanical pump 24 to cool the first refrigerant and cools an engine 12 with the cooled first refrigerant. The second cooling cycle circulates a second refrigerant to guide the second refrigerant to a rotary electric machine. The heat exchanger conducts heat exchange between the first refrigerant and the second refrigerant. The first electric pump circulates the first refrigerant in the first cooling cycle.SELECTED DRAWING: Figure 1

    【課題】回転電機の駆動による走行中に、簡単な構成でトランスミッションや回転電機の冷却性を高めることができる車両冷却サイクルを提供する。【解決手段】車両冷却サイクル15は、第1冷却サイクル16と、第2冷却サイクル17と、熱交換器26と、第1電動ポンプ25とを備えている。第1冷却サイクルは、第1冷媒を第1機械式ポンプ24で循環させて冷却し、冷却した第1冷媒でエンジン12を冷却する。第2冷却サイクルは、第2冷媒を循環させて回転電機に導く。熱交換器は、第1冷媒と第2冷媒との熱交換をおこなう。第1電動ポンプは、第1冷却サイクルにおいて第1冷媒を循環させる。【選択図】図1
