摘要

The present invention relates to the bottom guard, engine room structure, and cooling system in a construction machine. The bottom guard (23A) is mounted on a bottom portion (23) while facing an engine room (2B) through which air for cooling a cooling package (24) flows by operation of a cooling fan (25). The bottom guard (23A) is made up of a bottom guard main body (23B) and a guide member (23C). The bottom guard main body (23B) is mounted on the bottom portion (23) so as to cover the interior of the engine room (2B), and has a cooling-air discharge opening (23Ba). The guide member (23C) is disposed on an inside surface of the bottom guard main body (23B) mounted on the bottom portion (23) which faces the interior of the engine room (2B), so as to cover the cooling-air discharge opening (23Ba). The guide member (23C) is also used for guiding the cooling air discharged from the cooling fan (25), from the outer periphery of the cooling fan (25) to the cooling-air discharge opening (23Ba). The cooling air in a centrifugal direction, which occupies the greater part of the cooling air discharged from the cooling fan (25), is guided out of the engine room (2B) by the guide member (23C), so it is discharged smoothly out of the engine room (2B).
