[0002] The hydraulic station is a hydraulic source device consisting of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc., or a hydraulic device including a control valve. It supplies oil according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines in which the driving device is separated from the hydraulic station. By connecting the hydraulic station and the driving device (cylinder or motor) with an oil pipe, the hydraulic system can achieve various specified actions.

[0003] During the operation of the existing hydraulic station, a large amount of heat will be generated due to the friction and compression of the hydraulic oil when the hydraulic pump, motor, control valve and other components are running. The heat contained in the hydraulic oil in the oil tank needs to be dissipated to keep the oil temperature within the normal working range. Once the hydraulic oil temperature is too high, it may cause the performance of the hydraulic oil and the stability of the hydraulic system. Therefore, we propose a hydraulic station that is easy to dissipate heat. Utility Model Content
