ABSTRACT:
A control unit cooling device for an industrial vehicle that can efficiently cool the control unit, wherein the control unit includes a cooling portion integrally formed with an electric circuit. In one embodiment of the invention, the control unit cooling device may be implemented on an industrial vehicle, such as a counterbalanced forklift. The cooling device has a first air current generation mechanism and a second air current generation mechanism. The first air current generation mechanism generates a first air current from air drawn in from the outside of a vehicle body. The first air current cools the electric circuit. The second air current generation mechanism generates a second air current from air drawn in from the outside of the vehicle body. The second air current cools the cooling portion. This efficiently cools the control unit.
