CONSTRUCTION MACHINE ENGINE ROOM CONSTRUCTION AND CONSTRUCTION MACHINE COOLING DEVICE

摘要

The present invention relates to the engine room structure and cooling system in a construction machine. An introduction opening (22c) and discharge opening (22a) are formed in a wall surface (22) of the engine room (2B) . A cooling-air guiding member (31), formed on the outer surface of the wall, guides cooling air from a side opposite to the discharge opening (22a) to the introduction opening (22c) . The cooling of engine cooling water and pump working oil by a cooling package (24) is consequently performed effectively.
