  • Construction machine
    Patent number: 11305641
    Abstract: A construction machine in which an electrical unit can be reliably cooled at low cost by effectively utilizing an intake pipe connected to an intake port of an engine. This construction machine includes: an engine; and a hood covering the engine, wherein a space inside the hood has a placement space in which an electrical unit is placed and which communicates with outside air, and a distal-end opening of an intake pipe connected to an inlet port of the engine is disposed in the placement space to cause outside air sucked into the intake pipe due to a suction pressure occurred in the intake pipe to pass through the placement space to form a cooling air path in the placement space.
    Type: Grant
    Filed: August 7, 2020
    Date of Patent: April 19, 2022
    Assignee: YANMAR POWER TECHNOLOGY CO., LTD.
