Construction machine
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.
1. A construction machine comprising:
an engine;
a hood covering the engine;
a space inside the hood including a placement space which communicates with outside air;
a distal-end opening of an intake pipe connected to an inlet port of the engine disposed in the placement space;
an intake duct having an outside-air inlet port through which outside air is drawn disposed in the placement space; and
a communication port disposed downward of the outside-air inlet port disposed in the placement space, the distal-end opening of the intake pipe disposed upward of the communication port.
2. The construction machine of claim 1 , wherein the outside-air inlet port is disposed upward of the communication port.
3. The construction machine of claim 2 , wherein an electrical unit is positioned in the placement space, the electrical unit disposed upward of the communication port and downward of the distal-end opening of an intake pipe.
