Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic station cooling systems, and in particular to a hydraulic station cooling system. Background Technology

[0002] A hydraulic power unit is a hydraulic source device or a hydraulic system including control valves, consisting of a hydraulic pump, a drive motor, an oil tank, directional valves, throttle valves, and relief valves. It supplies oil according to the flow direction, pressure, and flow rate required by the drive device. It is suitable for various machines where the drive device and hydraulic power unit are separate. By connecting the hydraulic power unit to the drive device (cylinder or motor) with oil pipes, the hydraulic system can achieve various specified actions.

[0003] Hydraulic power units play a significant role in hydraulic transmission systems. In many situations, they require a cooling system. For example, in environments with high ambient temperatures, enclosed production workshops, and especially under conditions of high speed, heavy loads, and prolonged operation, a cooling system is essential to lower the temperature of the hydraulic oil and ensure stable operation of the hydraulic power unit.

[0004] Application No. 201520204973.7 discloses a hydraulic station cooling system, relating to a system for cooling heat-generating equipment. Its purpose is to provide a hydraulic station cooling system with a simple structure and significant cooling effect. This utility model discloses a hydraulic station cooling system, comprising: a cooling tower, a hydraulic station, and a main water pump; the outlet of the hydraulic station is connected to the inlet of the cooling tower via the main water pump, and the outlet of the cooling tower is connected to the inlet of the hydraulic station; the cooling tower, hydraulic station, and main water pump together constitute a thermal circulation system.

[0005] In the aforementioned hydraulic station cooling system, the cooling water used for heat exchange with the radiator fins is continuously circulated. To maintain the equipment's heat exchange efficiency and reduce the cooling tower's failure rate, it is necessary to maintain the cleanliness of the cooling water. The only possibility of cooling water contamination is the introduction of cooling air, making the cleanliness of the cooling air particularly important. The airflow diverter in this application is filled with sufficient filter material, such as activated carbon or filter cotton. When the cooling air passes through this filter material, any entrained solid particles are completely filtered out.

[0006] Cooling air can be effectively kept clean when passing through filter materials, but the filter materials will seriously affect the speed at which the cooling air enters the cooling tower, reduce the heat exchange efficiency between the cooling air and the heat sink, waste resources, and reduce the cooling efficiency of the hydraulic station.
