PROBLEM TO BE SOLVED: To suppress reduction of an intake amount of air during traveling of a vehicle.SOLUTION: A cooling device for a vehicle comprises a cylindrical duct 23 which takes air that has gone through a heat exchanger 20 in from an air intake port 23a and discharges it from an air takeout port 23b, with the duct 23 having a pipe diameter changing part 232 in which its diameter gradually changes as it approaches the air takeout port 23b in such a manner that swirls are generated in the air that has gone through the duct because of the pipe diameter changing part 232 and a negative pressure is produced at the vehicle rear side from the duct.SELECTED DRAWING: Figure 5
【課題】車両の走行時における空気の取り込み量の低下を抑制する。【解決手段】熱交換器20を通過した空気を空気取込口23aより取り込んで空気取出口23bより排出する筒状のダクト23を備え、ダクト23は、空気取出口23bに近付くにつれて次第に径が変化する管径変化部232を有し、該管径変化部232によりダクト内を通過した空気に渦が生じてダクトより車両後方側が負圧となるよう構成されている。【選択図】図5
