Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil tank technology, and more specifically, to a hydraulic oil tank with cooling function. Background Technology

[0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays a role in energy transmission, anti-wear, system lubrication, corrosion prevention, rust prevention, and cooling in hydraulic systems. Hydraulic oil tanks are often used for storing hydraulic oil.

[0003] In existing technologies, traditional hydraulic oil cooling methods mostly involve placing the hydraulic tank in a water tank filled with cooling water for cooling. However, the water in the tank is not fluid, and after cooling the hydraulic oil, the water in the tank heats up, thus reducing the cooling effect on the hydraulic oil. Application No. 202323275711.3 discloses a hydraulic oil tank with a cooling function, including a tank body. The two ends of the tank body are respectively connected to an oil inlet pipe and an oil outlet pipe, and valve body one and valve body two are respectively fixedly connected inside the oil inlet pipe and the oil outlet pipe. The above device exchanges heat on the outer wall of the hydraulic oil tank through the flow of cooling pipes. The heat exchange effect is not direct enough. Furthermore, installing a cooler on the outside of the hydraulic oil tank will greatly increase the overall size of the equipment and significantly increase the overall cost of the equipment, making it impractical.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a hydraulic oil tank with cooling function to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A hydraulic oil tank with cooling function includes an oil tank body, a protective shell fixedly fitted on the outside of the oil tank body, radiators connected to the left and right sides of the protective shell respectively, a cooling box provided outside the radiators, a flange connected to the front of the oil tank body, and an oil outlet pipe connected through the flange, an oil inlet pipe connected through the top of the oil tank body, the oil inlet pipe penetrating the top of the protective shell, and a connecting pipe connected to the front of the cooling box.

[0008] Preferably, the protective housing includes an outer shell and an inner shell, the inner shell being fixedly connected inside the outer shell, and a through hole being provided at the top of the outer shell and the inner shell, the through hole being fixedly connected to an oil inlet pipe.

[0009] Preferably, a liquid storage tank is provided on the inner wall of the inner shell, and coolant is filled between the inner wall of the liquid storage tank and the outer wall of the oil tank body. Sealing strips are fixedly connected to the front and rear edges of the inner shell and are fixedly connected to the front and rear edges of the outer wall of the oil tank body through the sealing strips.

[0010] Preferably, a first mounting cavity is provided above the cooling box wall cavity, and a second mounting cavity is provided below the wall cavity. A circulation pump is fixedly connected to the left side of the inner wall of the first mounting cavity. The input end of the circulation pump extends into the liquid storage tank through a pipe, and the output end is fixedly connected to the top of the connecting pipe.

[0011] Preferably, the radiator includes heat dissipation fins and heat-conducting plates. The rear side of the heat dissipation fins is fixedly connected to the heat-conducting plates. The heat dissipation fins are equidistantly arranged on the left and right sides of the protective shell, and the heat-conducting plates are fixedly inserted into the liquid storage tank.

[0012] Preferably, a curved infusion tube is fixedly connected between the heat dissipation fins, the top end of the curved infusion tube is fixedly connected to the bottom end of the connecting tube, and the bottom end of the curved infusion tube is fixedly connected to the inside of the liquid storage tank.

[0013] Preferably, a fixing plate is fixedly connected between the inner walls of the second mounting cavity and the fixing plate is covered with a dustproof mesh plate, which is fixedly connected to the inner wall of the second mounting cavity.

[0015] The beneficial effects of this utility model are as follows: Compared with using the infusion pipeline to contact the outer wall of the oil tank body, the cooling effect of the coolant contacting the outer wall surface of the oil tank body is more direct and effective. The heat dissipation fins can dissipate the heat conducted by the heat conduction fins and the heat conducted by the outer wall of the curved infusion pipe. The design structure is simpler and more reasonable. The coolant can be circulated by the circulation pump, and the coolant can be cooled while flowing, so that the cooling effect of the coolant remains stable. There is no need to use special refrigeration compressor equipment for operation, which greatly reduces the overall cost of the equipment. Attached Figure Description

The inner shell 10 has a liquid storage tank 12 carved into its inner wall.

The liquid storage tank 12 is filled with coolant, and the sealing strips 13 are fixedly connected to the front and rear edges of the outer wall of the fuel tank body 1, which can prevent coolant leakage and allow the coolant to directly contact the outer wall of the fuel tank body 1. Compared with using a liquid delivery pipeline to contact the outer wall of the fuel tank body 1, the cooling effect of the coolant contacting the surface of the outer wall of the fuel tank body 1 is more direct and effective. Example

[0026] like Figure 1-4As shown, a hydraulic oil tank with cooling function according to an embodiment of the present invention includes an oil tank body 1, a protective shell 2 fixedly fitted on the outside of the oil tank body 1, radiators 3 connected to the left and right sides of the protective shell 2 respectively, a cooling box 4 provided outside the radiators 3, a flange 5 connected to the front of the oil tank body 1, and an oil outlet pipe 6 connected through the flange 5, an oil inlet pipe 7 connected through the top of the oil tank body 1, the oil inlet pipe 7 penetrating the top of the protective shell 2, a connecting pipe 8 connected to the front of the cooling box 4, a first mounting cavity 14 provided above the wall cavity of the cooling box 4, and a second mounting cavity 15 provided below the wall cavity, a circulation pump 16 fixedly connected to the left side of the inner wall of the first mounting cavity 14, the input end of the circulation pump 16 extending into the liquid storage tank 12 through a pipe, and the output end fixedly connected to the top of the connecting pipe 8, the radiator 3 including heat dissipation fins 17 and heat conduction plates 18, the rear side of the heat dissipation fins 17 being fixedly connected to the heat conduction plates 18.

The heat conduction plates 18 penetrate the inner side of the inner shell 10 and are immersed in the coolant. By starting the circulation pump 16, the circulation pump 16 can pump the coolant inside the liquid storage tank 12, and then transport it into the curved liquid delivery pipe 19 through the connecting pipe 8. The coolant is then reinjected into the liquid storage tank 12 through the curved liquid delivery pipe 19. The heat dissipation fins 17 can dissipate the heat conducted by the heat conduction plates 18 and the heat conducted by the outer wall of the curved liquid delivery pipe 19. The design structure is simpler and more reasonable. The coolant can be circulated by the circulation pump 16. Example

There is an exhaust fan 22, and blower fans 23 are fixedly connected to the four corners of the front side of the fixing plate 20. The inner side of the fixing plate 20 is fixedly connected to the front side of the heat dissipation fins 17. The heat dissipation fins 17 absorb the heat in the coolant and the heat on the outer wall of the curved inlet pipe 19. Then, by starting the blower fans 23 and the exhaust fans 22, the blower fans 23 blow air into the second mounting cavity 15, and the exhaust fans 22 blow the high temperature on the surface of the heat dissipation fins 17. This can accelerate the air circulation rate inside the second mounting cavity 15, and cool the coolant while it is flowing.
