CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/149979
Kind Code:
A1
Abstract:
Provided is a construction machine in which an electronic unit can be reliably cooled at low cost by effectively utilizing a suction pipe connected to an intake port of an engine. In the present invention, an installation space in which an electronic unit is installed is formed, so as to communicate with outside air, in a hood that covers an engine, and an end opening of a suction pipe that is connected to an intake port of the engine is disposed inside the installation space. As a result of the outside air being sucked into the suction pipe through the interior of the installation space by the suction pressure generated in the suction pipe, a cooling-air passage is formed in the installation space.
