Provided is a work vehicle that enables effective cooling of an engine, torque converter oil, and hydraulic oil. The present invention is provided with an engine (11), a torque converter (12), a hydraulic work device (15) operated with hydraulic oil (31), a radiator (16) for radiating the heat of engine-cooling water (32) for cooling the engine (11), an oil cooler (17) for radiating the heat of the hydraulic oil (31), and a heat exchanger (19) for performing heat exchange on the hydraulic oil (31) and the torque converter oil (33) used in the torque converter (12). Heat of the torque converter oil (33) is radiated by the oil cooler (17) by means of the hydraulic oil (31) due to the heat exchange between the torque converter oil (33) and the hydraulic oil (31). Both the radiator (16) and the oil cooler (17) are able to radiate heat while the vehicle is traveling whereby effective cooling of the engine (11), the torque converter oil (33), and the hydraulic oil (31) can be achieved. |
