Description

Technical Field

[0001] The utility model relates to the field of hydraulic equipment, in particular to a water cooling component for a hydraulic station. Background Art

[0002] When the hydraulic pump of the hydraulic station is working, the temperature of the hydraulic oil in the hydraulic oil tank will gradually increase. Excessive oil temperature will accelerate the aging of important components in the hydraulic pump, such as seals, and reduce their service life.

[0003] To lower the temperature of the hydraulic oil, existing technologies typically use heat pipe air cooling, but this still doesn't completely solve the heat dissipation problem in hydraulic oil tanks. Another method is to install a fan above the hydraulic oil to cool the hydraulic oil surface through air convection. Although this method is cost-effective, it has little overall effect on lowering the oil temperature.

[0004] For this purpose, application number: CN201521043064.6 proposes a water-cooled hydraulic station, in which the cooling water jacket of the water-cooled hydraulic station is rotatable and cooling is performed on different positions, resulting in a better cooling effect. At the same time, the cooling pipe is inserted deep into the oil tank to improve the cooling effect, greatly reduce the oil temperature of the hydraulic oil, and increase the service life of the hydraulic device. However, the adjacent area between the cooling water of the device and the hot oil in the hydraulic oil tank is small, which affects the cooling effect, and the water cooling pipe needs to pass through the interior of the hydraulic oil tank, which makes the hydraulic oil tank difficult to process and repair. Summary of the Invention

[0006] Preferably, the heat sink divides the hydraulic oil tank and the water-cooled shell into several cooling water flow channels, and the number and position of the water pipes on each end plate correspond one-to-one to the flow channels.

[0011] The utility model is externally connected to a circulating cooling water system. The cooling water is diverted by a switching device to a plurality of flow channels surrounded by heat sinks on the outside of the hydraulic oil tank, performs heat exchange with the hot oil in the hydraulic oil tank, and is then collected by the switching device into the circulating cooling water system.
