PROBLEM TO BE SOLVED: To provide construction machinery capable of contributing to an increase in efficiency of a heat exchanger by restraining biased distribution of the volume of cooling air from being caused by a region of the heat exchanger within a power house.SOLUTION: Construction machinery includes: a power house 1 that has an inlet port 2 and an exhaust port 6; a driving source 5 that is arranged in the power house 1; a fan 4 that is driven by the driving source 5 to induce a cooling air flow, directed toward the exhaust port 6 from the inlet port 2, within the power house 1; a heat exchanger 3 that is arranged in such a manner as to face the cooling air flow induced by the fan 4; and an air-straightening device 10 that guides some of the cooling air, directed toward a central part of the heat exchanger 3, to an outer peripheral part of the heat exchanger 3. |
