Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pump stations, and more specifically to a high-pressure electric hydraulic pump station. Background Art

[0002] The hydraulic pump 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. During the use of the high-pressure electric hydraulic pump station, the hydraulic oil will be cooled by a cooling mechanism. The cooling range is small, which reduces the cooling and heat dissipation effect of the entire high-pressure electric hydraulic pump station. In addition, the heat sink provided by the cooling mechanism dissipates heat naturally, which reduces its heat dissipation effect on the cooler assembly and may shorten its service life.

[0003] For example, announcement number CN219492778U discloses a high-pressure electric hydraulic pump station, which includes a hydraulic pump station body, a support frame welded on the side wall of the hydraulic pump station body, a dust cover hinged on the side wall of the support frame, a dust-proof ventilation mechanism is arranged on the side wall of the dust cover, and a cooling mechanism is arranged on the side wall of the hydraulic pump station body.

[0004] It can be seen from the above-mentioned public scheme that the cooling mechanism can only cool the hydraulic oil, but cannot cool down and dissipate heat for other heat-generating components of the hydraulic pump station, which greatly reduces the heat dissipation effect of the entire hydraulic pump station. In addition, the cooling mechanism dissipates heat for its cooler component through the provided heat dissipation fins. Since the heat dissipation fins dissipate heat naturally, the heat dissipation effect of the cooler component is poor, causing the cooler component to operate in a high-temperature environment for a long time, which not only affects its refrigeration effect, but also shortens the service life of the component.
