Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinders, specifically a hydraulic cylinder with high-efficiency heat dissipation. Background Technology

[0002] A hydraulic cylinder, also known as a hydraulic pump, uses a booster rod to force hydraulic oil into the cylinder. Once inside, the hydraulic oil is prevented from flowing backward by a check valve, thus pushing the piston upward and converting mechanical energy. When downward movement is needed, the hydraulic valve opens, allowing the hydraulic oil to return to the tank, reversing the cylinder's movement.

[0003] Existing hydraulic cylinders typically consist of a cylinder barrel, piston, piston rod, and sealing device. The cylinder barrel is the main body of the hydraulic cylinder, used to house the hydraulic oil and piston. The piston is the key component of the hydraulic cylinder, capable of reciprocating motion within the cylinder barrel. It is connected to the piston rod, which transmits force and motion. The sealing device prevents hydraulic oil leakage, ensuring the normal operation of the hydraulic cylinder.

[0004] However, traditional hydraulic cylinders are prone to overheating under high loads and prolonged operation. This is mainly because hydraulic cylinders generate a large amount of heat during operation, while their heat dissipation area is relatively limited. This restricts the improvement of their heat dissipation performance, leading to an increase in the operating temperature of the hydraulic cylinder and affecting its performance and lifespan.

[0005] To address this issue, those skilled in the art have proposed a hydraulic cylinder with high-efficiency heat dissipation to solve the problems mentioned in the background art. Utility Model Content

A liquid storage cylinder, a heat conduction cylinder, and a cylinder are located inside the cover on the top of the base. A piston rod is movably mounted on the top of the cylinder and passes through the cover. The heat conduction cylinder covers the outside of the cylinder. The outer wall of the cylinder is spirally wound with heat dissipation fins and cooling pipes. The two ends of the cooling pipes are respectively connected to an inlet pipe and a return pipe. Both the inlet pipe and the return pipe pass through the heat conduction cylinder and are connected to the liquid storage cylinder. The heat dissipation fins spirally extend out of the heat conduction cylinder. An air-cooling component is also movably mounted on the base on one side of the heat conduction cylinder.

[0010] Preferably, the gas pipeline is configured with a corrugated adaptive telescopic structure, which is used to adaptively extend or shorten as the vertical pipe moves.

[0011] Preferably, the movable guide includes a movable block, a rotating shaft, and a connecting rod. A semi-annular groove is provided on the top of the base, and a guide shaft is provided inside the semi-annular groove. The movable block is slidably arranged on the guide shaft.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a high-efficiency heat dissipation hydraulic cylinder, including a base 1, on which a cover 2 is provided. The top of the cover 2 is provided with a liquid storage cylinder 3, a heat conduction cylinder 4 and a cylinder 5 located inside the cover 2. A piston rod 6 is movably arranged on the top of the cylinder 5, passing through the cover 2. The heat conduction cylinder 4 covers the outside of the cylinder 5. The outer wall of the cylinder 5 is spirally wound with heat dissipation fins 7 and cooling pipes 8. The two ends of the cooling pipes 8 are respectively connected to an inlet pipe 9 and a return pipe 10. Both the inlet pipe 9 and the return pipe 10 pass through the heat conduction cylinder 4 and communicate with the liquid storage cylinder 3. The heat dissipation fins 7 spirally pass through the heat conduction cylinder 4. An air-cooling component located on one side of the heat conduction cylinder 4 is also movably arranged on the base 1.

[0027] The cooling pipe 8 and the heat dissipation fins 7 are in direct contact with the cylinder 5, thus directly dissipating heat from it. The heat conduction cylinder 4 is in contact with the heat dissipation fins 7, thus indirectly dissipating heat from the cylinder 5.

[0028] refer to Figure 2 A micro pump 11 is provided in the middle of the return pipe 10. The micro pump 11 is installed on the top of the base 1 and is used to draw the cooling medium in the cooling pipe 8 into the liquid storage tank 3.

[0029] The liquid storage tank 3 is made of copper. The cooling medium in the cooling pipe 8 can be drawn into the liquid storage tank 3 by the micro pump 11 for heat exchange, so that the cooling medium can be recycled.

[0030] refer to Figure 2and Figure 3 The air-cooled assembly includes a cooler 12, an air supply pipe 13, a vertical pipe 14, and a moving guide. The vertical pipe 14 is movably mounted on the top of the base 1 in a semi-circular trajectory via the moving guide. The cooler 12 is installed on the outside of the cover 2. The air outlet of the cooler 12 is connected to the air supply pipe 13. One end of the air supply pipe 13 is connected to the vertical pipe 14. Multiple air blowing holes 15 are vertically and equidistantly opened on the outside of the vertical pipe 14.

[0031] In this process, the cold air generated by the air cooler 12 is delivered to the vertical pipe 14 through the air supply pipe 13, and finally blown out evenly towards the heat dissipation fins 7 through the air blowing hole 15. During the air cooling process, the vertical pipe 14 is moved along a semi-circular trajectory by the moving guide component, thereby dissipating heat from multiple angles to the spirally arranged heat dissipation fins 7, thus improving its heat dissipation effect.

[0032] refer to Figure 2 The gas supply pipe 13 is configured with a corrugated adaptive telescopic structure, which is used to adaptively extend or shorten as the vertical pipe 14 moves.

[0033] refer to Figure 3 and Figure 4 The movable guide includes a movable block 16, a rotating shaft 17, and a connecting rod 18. A semi-annular groove 19 is provided on the top of the base 1. A guide shaft 20 is provided in the semi-annular groove 19. The movable block 16 is slidably arranged on the guide shaft 20. The bottom end of the vertical tube 14 is connected to the top of the movable block 16. The rotating shaft 17 is rotatably arranged inside the base 1. The connecting rod 18 and a driving component are provided on the rotating shaft 17. One end of the top of the connecting rod 18 is connected to the bottom of the movable block 16.

[0034] The rotating shaft 17 is driven to rotate by a driving component. When the rotating shaft 17 rotates, it pulls the moving block 16 along the guide shaft 20 and the semi-annular groove 19 through the connecting rod 18. During the movement, the blowing angle of the vertical pipe 14 can be changed.

[0035] refer to Figure 1 The driving components include a gear 21, a toothed plate 22, a motor 23, a screw 24, and a nut pair 25. The motor 23 is mounted on one end of the base 1, and its output end passes through the base 1 and is connected to the screw 24. The screw 24 is threadedly connected to the nut pair 25, and the toothed plate 22 is connected to the nut pair 25. The gear 21 is mounted on the rotating shaft 17 and meshes with the toothed plate 22.

[0036] refer to Figure 3 A guide rod 26 is horizontally arranged inside the base 1, and the toothed plate 22 is slidably connected to the guide rod 26.

[0037] Among them, the screw 24 is driven to rotate by the motor 23. During the rotation of the screw 24, it cooperates with the nut pair 25 to drive the toothed plate 22 to move horizontally along the limit rod. When the toothed plate 22 moves, it meshes with the gear 21, and the meshing force drives the rotating shaft 17 to rotate.

[0038] Working principle: When the hydraulic cylinder is working, the cooling pipe 8 and the heat dissipation fins 7 directly contact the cylinder barrel 5, thus directly dissipating heat. The heat conduction cylinder 4 also contacts the heat dissipation fins 7, thus indirectly dissipating heat from the cylinder barrel 5. The micro pump 11 draws the cooling medium in the cooling pipe 8 into the liquid storage tank 3 for heat exchange, allowing the cooling medium to be recycled. By starting the motor 23 and the air cooler 12, the air cooler 12 delivers the generated cold air through the air supply pipe 13 to the vertical pipe 14, and finally blows it evenly towards the heat dissipation fins through the air blowing holes 15. 7. During the air-cooling process, the motor 23 drives the screw 24 to rotate. When the screw 24 rotates, it cooperates with the nut pair 25 to drive the toothed plate 22 to move horizontally along the limit rod. When the toothed plate 22 moves, it meshes with the gear 21. The meshing force drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it pulls the moving block 16 along the guide shaft 20 and the semi-annular groove 19 through the connecting rod 18. During the movement, the blowing angle of the vertical pipe 14 can be changed, thereby dissipating heat from multiple angles to the spirally arranged heat dissipation fins 7, improving the overall heat dissipation effect on the cylinder 5.
