PROBLEM TO BE SOLVED: To suppress rise of a temperature in an engine room, particularly, to avoid useless temperature elevation of a peripheral device thereby further enhancing reliability of the peripheral device.SOLUTION: In constituting a cooling device 1 for an engine of a vehicle comprising a radiator 2 for cooling an engine E as a power source for a vehicle by a coolant and a cooling fan 3 which passes outdoor air A for heat exchanging through the radiator 2 thereby cooling the coolant, an auxiliary ventilation path 5 is provided. The auxiliary ventilation path is so configured that a ventilation outlet 5e is so made as to face blast on an upstream side or a downstream side of the cooling fan 3, and a ventilation inlet 5i is so made as to face non-heat exchange outdoor air As which does not pass through the radiator 2, whereby non-heat exchange outdoor air Qs of air quantity Qs, which is less than air quantity Qr which passes through the radiator 2, is discharged into blast on the upstream side or the downstream side of the cooling fan 3.SELECTED DRAWING: Figure 1

    【課題】 エンジンルーム内の温度上昇を抑制し、特に周辺機器の無用な高温化を回避することにより、周辺機器の信頼性をより高める。【解決手段】 車両Mの動力源となるエンジンEを冷却液により冷却するラジエータ2及びこのラジエータ2に熱交換用の外気Aを通過させて冷却液を冷却する冷却ファン3を備える車両のエンジン冷却装置1を構成するに際して、通気出口5eを、冷却ファン3の上流側の送風中又は下流側の送風中に臨ませるとともに、通気入口5iを、ラジエータ2を通過しない非熱交換外気As中に臨ませることにより、ラジエータ2を通過する空気量Qrよりも少ない空気量Qsの非熱交換外気Asを、冷却ファン3の上流側の送風中又は下流側の送風中に放出する補助通気路5を設ける。【選択図】 図1
