Title:
CONSTRUCTION MACHINE BOTTOM GUARD, CONSTRUCTION MACHINE ENGINE ROOM CONSTRUCTION AND CONSTRUCTION MACHINE COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/106710
Kind Code:
A1
Abstract:
The invention relates to a construction machine bottom guard, a construction machine engine room construction and a construction machine cooling device, wherein a bottom guard (23A) is attached to a machine body bottom (23) to face an engine room (2B) through which cooling air for cooling a cooling package (24) by the operation of a cooling fan (25) passes, the bottom guard (23A) being composed of a bottom guard main body (23B) attached to the machine body bottom (23) in such a manner as to shield the interior of the engine room (2B) with respect to the space outside the machine and having a cooling air discharge opening (23Ba), and a guide member (23C) attached to the side facing the interior of the engine room (2B) in a state in which the bottom guard main body (23B) is attached to the machine body bottom (23), so as to cover the cooling air discharge opening (23Ba) and adapted to guide the cooling air delivered from the cooling fan (25) from the outer periphery of the cooling fan (25) to the cooling air discharge opening (23Ba). Since the centrifugally delivered cooling air forming a larger proportion of the cooling air delivered from the cooling fan (25) is guided outside the machine by the guide member (23C), the cooling air is smoothly discharged outside the machine.
