To provide a cooling system which can cool a vehicle rotary electric machine efficiently.SOLUTION: A cooling system 10 includes a refrigeration cycle device 100 for air conditioning and a rotary electric machine cooling mechanism 200. The refrigeration cycle device 100 for air conditioning includes: a compressor 110; a radiator 120; a first expansion valve 130; a first evaporator 140; and a branch passage 160 which connects an upstream side passage 151 provided between the radiator 120 and the first expansion valve 130 to a downstream side passage 152 provided between the first evaporator 140 and the compressor 110. The rotary electric machine cooling mechanism 200 is provided at the branch passage 160 and has a second expansion valve 210 and a second evaporator 220 from the upstream side in a written order, and the second evaporator 220 is disposed in the vehicle rotary electric machine 1.SELECTED DRAWING: Figure 1

    【課題】車両用回転電機を効率的に冷却できる冷却システムを提供する。【解決手段】冷却システム10は空調用冷凍サイクル装置100と回転電機冷却機構200とを備える。空調用冷凍サイクル装置100は、コンプレッサ110と、ラジエータ120と、第1エキスパンションバルブ130と、第1エバポレータ140と、ラジエータ120と第1エキスパンションバルブ130との間に設けられた上流側流路151と第1エバポレータ140とコンプレッサ110との間に設けられた下流側流路152とを接続する分岐流路160と、を備える。回転電機冷却機構200は、分岐流路160に設けられ、上流側から順に第2エキスパンションバルブ210と第2エバポレータ220とを有し、車両用回転電機1に第2エバポレータ220が配置される。【選択図】図1
