PROBLEM TO BE SOLVED: To provide a cooling device allowing air flow to pass through the whole region of a heat exchanger.SOLUTION: A cooling device 20 which blows air to a heat exchanger 10 arranged on the front side of a vehicle by using a blower 30 includes: a front part duct 40 formed of ejector nozzles 41 which are arranged over a plurality of stages on the vehicle front side FD of the heat exchanger 10 and blows air sent from the blower 30 toward the heat exchanger 10; and a pair of lateral part ducts 50 which are arranged on both lateral parts 40E of the front part duct 40 and relays air sent from the blower 30 to the front part duct 40. A pair of lateral part ducts 50 have duct attachment surfaces 56 to which respective lateral parts 40E of the front part duct 40 are attached. A pair of duct attachment surfaces 56 are configured such that an interval S between the duct attachment surfaces gets to narrower toward the heat exchanger 10 from a vehicle front side FD and air from the vehicle front side FD is guided toward the heat exchanger 10. |
