Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic system cooling devices, specifically a hydraulic system cooling device for a roadway repair machine. Background Technology

[0002] The function of a hydraulic system is to increase force by changing pressure. A complete hydraulic system consists of five parts: power element, actuator, control element, auxiliary elements (accessories), and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. Hydraulic transmission systems primarily function to transmit power and motion. Hydraulic control systems, on the other hand, ensure that the hydraulic system output meets specific performance requirements (especially dynamic performance). The term "hydraulic system" usually refers primarily to the hydraulic transmission system.

[0003] Existing hydraulic system cooling devices have the following drawbacks:

[0004] Existing hydraulic system cooling devices have a slow cooling rate and insignificant cooling effect on the cooling oil, which affects the use of the hydraulic system.

[0005] Therefore, a solution is needed. Utility Model Content

The water in the tank can be easily circulated, thereby lowering the temperature of the cooling water. When the water circulation is interrupted, the heat can be transferred to the heat conduction strips, and then the fan dissipates heat from the heat conduction strips, thereby achieving the purpose of cooling down.

The cooling device 3 includes a first cooling ring 6, a second cooling ring 7, a third cooling ring 8, a fourth cooling ring 9, a fifth cooling ring 10, a sixth cooling ring 11, and a connecting pipe 12. The first cooling ring 6, the second cooling ring 7, the third cooling ring 8, the fourth cooling ring 9, the fifth cooling ring 10, and the sixth cooling ring 11 are arranged in a row-shaped equidistant arrangement. There are several sets of connecting pipes 12. The first cooling ring 6 and the second cooling ring 7 are connected by connecting pipes 12. The second cooling ring 7 and the third cooling ring 8 are connected by connecting pipes 12. The third cooling ring 8 and the fourth cooling ring 9 are connected by connecting pipes 12.

The right end of the first cooling ring 6 is provided with an oil inlet pipe 13, and the right side of the sixth cooling ring 11 is provided with an oil outlet pipe 14. During cooling, hydraulic oil enters the first cooling ring 6 through the oil inlet pipe 13, and then cooling water enters the cooling housing 2 through the water inlet pipe 15 to cool the hydraulic oil in the first cooling ring 6. Then, the hydraulic oil in the first cooling ring 6 enters the second cooling ring 7 through the connecting pipe 12. The hydraulic oil in the 7th cooling ring enters the third cooling ring 8 through the connecting pipe 12. The hydraulic oil in the third cooling ring 8 then enters the fourth cooling ring 9 through the connecting pipe 12. The hydraulic oil in the fourth cooling ring 9 then enters the fifth cooling ring 10 through the connecting pipe 12. Finally, the hydraulic oil in the fifth cooling ring 10 is discharged into the sixth cooling ring 11. The hydraulic oil in the sixth cooling ring 11 is finally discharged through the drain pipe 14. In this way, the hydraulic oil in the cooling shell 2 can be easily cooled by the cooling water, and the cooling water is discharged through the drain pipe 16, thus achieving the purpose of circulation.

[0023] The cooling housing 2 has a cylindrical structure. The cooling housing 2 and the top cover 5 have heat dissipation channels 22.

Several groups of heat-conducting holes 20 are provided on the surface of the heat-conducting strips 19 distributed in a row-shaped equidistant manner.

[0025] The support foot device 4 includes a support column 23, a support plate 24, and a rubber pad 25. The support plate 24 is installed on the top of the support column 23.

The cooling fan 21 can filter dust in the air when exhausting air.

[0026] Working principle: During operation, hydraulic oil enters the first cooling ring 6 through the oil inlet pipe 13. Then, cooling water enters the cooling shell 2 through the water inlet pipe 15 to cool the hydraulic oil in the first cooling ring 6. The hydraulic oil in the first cooling ring 6 then enters the second cooling ring 7 through the connecting pipe 12. The hydraulic oil in the second cooling ring 7 then enters the third cooling ring 8 through the connecting pipe 12. The hydraulic oil in the third cooling ring 8 then enters the fourth cooling ring 9 through the connecting pipe 12. The hydraulic oil in the fourth cooling ring 9 then enters the fifth cooling ring 10 through the connecting pipe 12. Finally, the hydraulic oil in the fifth cooling ring 10 is discharged into the sixth cooling ring 11. The hydraulic oil in the sixth cooling ring 11 is finally discharged through the oil drain pipe 14. In this way, the hydraulic oil in the cooling shell 2 can be easily cooled by the cooling water, and the cooling water is discharged through the drain pipe 16, achieving the purpose of circulation.
