COOLING DEVICE FOR VEHICLE

To reduce vibration of a duct of a cooling device for a vehicle and thereby to stabilize flow rate of air after reducing chatter sound.SOLUTION: The invention relates to a cooling device for a vehicle which cools electric equipment of the vehicle. The cooling device includes a blower which functions as a supply source of air sent so as to cool the electric equipment, a first duct which passes through air from the blower and an installation part which places the blower and the first duct. The first duct includes an upstream end part which is connected to the blower, a downstream end part which situates to side opposed to a flow direction to the upstream end part at plan view and an intermediate part which situates between upstream and downstream end parts at a flow direction at plan view. The downstream end part includes a striking wall which is disposed by spacing distance against the intermediate part so as to bend flow of the air from the intermediate part in the horizontal direction. The first duct includes a junction part which situates to side opposed to the intermediate part with respect to the striking wall at the flow direction at plan view and moreover which joins to the installation part.SELECTED DRAWING: Figure 5 【課題】車両用冷却装置のダクトの振動を低減し、これによって、ビビリ音を低減し、空気の流量を安定させる。【解決手段】本発明は、車両の電気機器を冷却する車両用冷却装置に関する。この冷却装置は、電気機器を冷却するように送られる空気の供給源となるブロワと、このブロワからの空気を通過させる第１ダクトと、ブロワ及び第１ダクトを載置した載置部とを有し、第１ダクトが、ブロワに接続される上流端部と、平面視にて上流端部に対して流れ方向の反対側に位置する下流端部と、平面視にて流れ方向にて上流及び下流端部間に位置する中間部とを有し、下流端部が、中間部からの空気の流れを水平方向にて屈曲させるように中間部と間隔を空けて配置される突き当り壁を有し、第１ダクトが、平面視にて、流れ方向にて突き当り壁に対して前記中間部とは反対側に位置し、かつ載置部に接合される接合部を有する。【選択図】図５
