PROBLEM TO BE SOLVED: To provide a work machine in which an air-cooled space in a machine chamber is reduced and the temperatures of an engine and hydraulic devices are efficiently controlled.SOLUTION: The work machine such as a hydraulic shovel includes a hydraulic pump 11 driven by the engine 10, an actuator 7 operated by the hydraulic oil supplied by the hydraulic pump 11, an air-cooled radiator 12 for cooling the engine 10, and a water circulation passage 30 through which the cooling water circulates between the radiator 12 and the engine 10. A water-cooled oil cooler 13 is connected to the downstream side of the radiator 12 in the water circulation passage 30. The hydraulic oil is cooled through the heat exchange thereof with the cooling water using the oil cooler 13. |
