COOLER FOR CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To efficiently capture an air flow generated by rotation of a fan to improve exhaust efficiency.

SOLUTION: In the construction machine that generates an air flow moving in a fan axial direction around an engine by rotation of a fan 12, an exhaust duct 18 with an air inlet 21 formed at the top and an air outlet formed at the bottom is disposed in a lower front part of the engine in an engine room 8 so as to extend the fan axial direction along the engine. The air flow on the downstream side of the fan is introduced by the exhaust duct 18 in an area substantially over the total engine length and discharged to the outside of the engine room.
