DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The present utility model will be specifically described below with reference to the drawings. As shown in the attached Figure 1 and the attached Figure 2 figures, a hydraulic pump station capable of achieving rapid cooling includes an upper oil tank 1. It is characterized in that support columns 2 are longitudinally fixedly connected to the four corners of the lower part of the upper oil tank 1 respectively, and a lower oil tank 3 is fixedly connected to the lower ends between the support columns 2. Among them, support legs 4 are fixedly connected to the four corners of the lower part of the lower oil tank 3 respectively; a hydraulic pump 5 is fixedly connected to the upper right rear side of the upper oil tank 1; a suction pipe 6 is fixedly connected to the opening in the middle of the right part of the lower oil tank 3, and the right end of the suction pipe 6 is connected to the input end of the hydraulic pump 5 through a pipeline; a return pipe 7 is fixedly connected to the opening in the upper right front side of the upper oil tank 1; an oil inlet hopper 8 is fixedly connected to the opening in the upper middle left side of the upper oil tank 1, and a hopper cover 9 is connected to the upper end of the oil inlet hopper 8; a first connecting pipe 10 is integrally connected to the opening in the middle of the lower part of the upper oil tank 1 from left to right in sequence; a second connecting pipe 11 is integrally connected to the opening in the middle of the upper part of the lower oil tank 3 from left to right in sequence.

[0013] One kind of hydraulic pump station capable of achieving rapid cooling further includes a close-contact cooling component 12, and the close-contact cooling component 12 is respectively detachably and hermetically fixedly connected between the first connecting pipe 10 and the second connecting pipe 11, which is conducive to achieving the effect of close-contact cooling, enabling the hydraulic oil to be in close contact with the refrigeration component, and the refrigeration component can still provide a lower temperature under the condition of higher external temperature, thereby effectively improving the cooling effect of the hydraulic oil.

[0014] Among them, the close-contact cooling component 12 respectively includes a rectangular cooling pipe 121, and a heat conduction plate 122 is integrally connected in the rectangular cooling pipe 121 in sequence from front to back; a semiconductor refrigeration sheet module 123 is fixedly connected to the middle part of the right side of the rectangular cooling pipe 121.

[0015] In this implementation scheme, specifically, the rectangular cooling pipe 121 is respectively detachably and hermetically fixedly connected to the inner sides between the first connecting pipe 10 and the second connecting pipe 11.

[0016] In this implementation scheme, specifically, the rectangular cooling pipe 121 is made of an aluminum alloy pipe with a rectangular cross-section.

[0017] In this implementation scheme, specifically, the heat conduction plate 122 is made of an aluminum alloy plate with a rectangular longitudinal section.

[0018] In this implementation scheme, the distance between every two adjacent heat conduction plates 122 is 3 - 5 mm.

[0019] In this implementation scheme, specifically, the first connecting pipe 10 and the second connecting pipe 11 are respectively made of aluminum alloy pipes with a rectangular cross-section.

[0020] In this implementation scheme, specifically, the hydraulic pump 5 and the semiconductor refrigeration sheet module 123 are respectively electrically connected to an external control panel.

[0021] In this implementation scheme, when using this hydraulic pump station, the operator can control the start of the semiconductor refrigeration sheet module 123 through an external control panel, so that the semiconductor refrigeration sheet module 123 provides cold energy to the rectangular cooling pipe 121. The rectangular cooling pipe 121 will also conduct the cold energy to the inside of the cold conduction plate 122. Subsequently, the operator can control the start of the hydraulic pump 5 through the external control panel, so that the hydraulic pump 5 sucks the hydraulic oil in the lower oil tank 3 through the pipeline and the oil suction pipe 6, and the hydraulic oil in the upper oil tank 1 will enter the inside of the rectangular cooling pipe 121 through the first connecting pipe 10. At this time, the hydraulic oil will come into contact with the rectangular cooling pipe 121 and the cold conduction plate 122. Since the cold conduction plates 122 are arranged at intervals of 3-5 mm, the contact area between the hydraulic oil and the cold medium can be increased through the cold conduction plates 122, and thus the cooling effect on the hydraulic oil can be effectively improved, achieving the effect of close-contact cooling. Since the semiconductor refrigeration sheet module 123 can generate a large amount of cold energy, even when the external environmental temperature is relatively high, the semiconductor refrigeration sheet module 123 can still provide a lower temperature for the rectangular cooling pipe 121, effectively avoiding the problem that the hydraulic oil cannot be cooled and effectively improving the cooling effect on the hydraulic oil.

[0022] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
