An apparatus for cooling oil in a tank of a forklift truck is provided to cool operation oil using a simplified structure for circulating cooling water in the tank without installation of an oil cooler. An apparatus for cooling oil in a tank of a forklift truck includes a temperature sensor(110), a pipe coil(120), an operation oil cooler water discharge line(L2), and a flow rate control valve(130). The temperature sensor is installed at a suction part of a hydraulic pump(10) for discharging operation oil from an oil tank(40). The operation oil discharged from the hydraulic pump is used in an actuator(20) and returned to the oil tank. The pipe coil is installed in the oil tank to provide a path for flowing the cooling water. The operation oil cooler water discharge line provides a flow path for supplying the cooling water into a radiator(50). The flow rate control valve is installed on a water introduction line to control flow of the cooling water. |
