Abstract

A construction machine includes an engine, a cooling fan, a hood, a heat exchanger, a partition plate, a battery, and a fuse box. The engine has electrical equipment. The cooling fan is mounted to the engine. The hood has an exhaust port. The heat exchanger is disposed between the cooling fan and the exhaust port. The partition plate defines an exhaust air channel between the heat exchanger and the exhaust port. The battery is disposed in a space under the partition plate. The fuse box is connected to a circuit joining the electrical equipment of the engine and the battery. The fuse box is disposed between the battery and the partition plate.
