Abstract
A working machine includes a battery unit; an electrical component; a radiator; an electrical-component cooling water channel along which cooling water delivered from an outflow port of the radiator is supplied to the electrical component and, after cooling the electrical component, circulates to an inflow port of the radiator; a switching unit provided on the electrical-component cooling water channel; and a battery cooling water channel along which the cooling water is supplied from the switching unit to the battery unit and, after cooling the battery unit, flows to the electrical-component cooling water channel. The switching unit is switchable between a first state of blocking a flow of the cooling water from the electrical-component cooling water channel to the battery cooling water channel and a second state of causing the cooling water to flow from the electrical-component cooling water channel to the battery cooling water channel.
