CONSTRUCTION MACHINE ENGINE ROOM CONSTRUCTION AND CONSTRUCTION MACHINE COOLING DEVICE

The present invention related to an engine room structure and cooling system of a construction machine. To discharge the cooling air passed through a cooling package (24), the engine room main body (21) of an engine room (2B) has a top wall surface (22) with an upper discharge opening (22a) and a bottom wall surface (23) with a lower discharge opening (23a). At least the upper discharge opening (22a) is disposed around the outer periphery of acoolingfan (25). Anuppercooling-airdeflectingmember (22b or 32a) is mounted on the top wall surface (22) to cover the upper discharge opening (22a) so that the cooling air discharged from the upper discharge opening (22a) is deflected in a horizontal direction. As a result, most of the cooling air sent out of the cooling fan 25 flows in the centrifugal direction and an efficiency of cooling-air discharge can be enhanced.
