Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic oil cooling equipment, and in particular to a hydraulic oil cooling device. Background Technology

[0002] Hydraulic oil cooling devices are key components in hydraulic systems used to control oil temperature. Their core function is to continuously dissipate the heat generated by the hydraulic oil during operation to the external environment through forced convection and heat exchange, keeping the oil temperature stable within a reasonable range. Effective heat dissipation can prevent oil oxidation, maintain viscosity stability, and thus ensure the long-term reliable operation of the hydraulic system and extend the life of components.

[0003] However, traditional fan cooling structures may not be able to quickly and evenly remove heat from the heat sink fins due to airflow rotation, unevenness, or insufficient air pressure, resulting in a bottleneck in heat dissipation efficiency. Furthermore, after long-term operation, traditional radiators will accumulate sludge and dirt on the oil pipes and heat sink fins, forming a heat insulation layer that severely reduces heat dissipation efficiency. Cleaning requires stopping the machine, disassembling, and performing physical or chemical cleaning, which is cumbersome, affects the continuous operation of the equipment, and has a short cleaning cycle.

[0004] Therefore, we propose a hydraulic oil cooling device to solve the above problems. Utility Model Content

A detachable cover is fixedly installed on one side of the cooling housing, and a mounting bracket is fixedly installed on one side of the cover. A protective shell is fixedly installed on the inner side of the mounting bracket. A forward-rotating wheel is rotatably installed on the inner wall of the protective shell on the side away from the mounting bracket, and a reverse-rotating wheel is rotatably installed on the inner wall of the other side of the protective shell. A quick-release opening is provided on the top of the cooling housing, and a cooling frame is snapped onto the inner side of the quick-release opening. Auxiliary openings are provided on both sides of the cooling frame, and cooling fins are fixedly installed on the inner side of each of the two auxiliary openings.

[0007] Specifically, a servo motor is fixedly installed on one side of the protective housing, and a double row of drive wheels is rotatably installed on the inner wall of one side of the protective housing. The output shaft of the servo motor extends into the inner side of the protective housing and is fixedly connected to the double row of drive wheels. The double row of drive wheels adopts a double groove design, which can drive two belts at the same time, simplifying the transmission structure and improving space utilization.

[0008] Specifically, the double-row drive pulley and the reverse pulley are connected by the same cross belt, and the double-row drive pulley and the forward pulley are connected by the same transmission belt. The cross belt adopts a toothed belt design to avoid transmission slippage and ensure that the reverse pulley and the double-row drive pulley rotate synchronously in reverse.

[0011] Specifically, the inner side of the heat dissipation frame is provided with an oil pipe, and the outer side of the oil pipe is fixedly fitted with multiple mounting clips. The two sides of the multiple mounting clips are respectively fixedly connected to the inner walls of the two sides of the heat dissipation frame. The output end and input end of the oil pipe both extend out of the top cover. The output end and input end of the oil pipe are respectively provided with an oil outlet and an oil inlet. The mounting clips are made of elastic rubber material, which both fixes the oil pipe and absorbs vibration.

[0012] Specifically, multiple cleaning clips are fixedly installed on the outside of the oil pipe, and each cleaning clip is fixedly installed with an ultrasonic transducer. The inside of the cleaning clip is equipped with a piezoelectric ceramic plate, which removes impurities attached to the surface of the oil pipe through high-frequency vibration.

[0013] Specifically, the heat dissipation casing has shock-absorbing grooves on both sides and the bottom inner wall.

[0028] In this embodiment, a top cover 17 is fixedly installed on the top of the heat dissipation frame 15, a handle 18 is fixedly installed on the top of the top cover 17, and two mounting plates 19 are fixedly installed on the top of the top cover 17.

[0032] Working Principle: During hydraulic oil cooling, the operator connects the inlet and outlet of oil pipe 21 to the output and input ends of the hydraulic system's oil tank, respectively. High-temperature hydraulic oil, driven by the internal circulation pump of the oil tank, flows into oil pipe 21. Heat is conducted from the oil to the metal pipe wall and the outer cooling fins 16 through the contact between the oil and the pipe wall. Simultaneously, the servo motor 5 starts, driving the double-row drive pulley 6 to rotate. The rotation of the double-row drive pulley 6 drives the reverse shaft 9 and the forward shaft 13 to rotate via the cross belt 8 and the transmission belt 12, respectively. The reverse shaft 9 rotates counterclockwise, and the forward shaft 13 rotates clockwise; their directions are opposite but do not interfere with each other. The rotation of the reverse shaft 9 drives the reverse fan 10 to rotate counterclockwise, and the rotation of the forward shaft 13 drives the forward fan 14 to rotate. The counterclockwise rotating airflow generated by the reverse fan 10 is straightened by the clockwise rotating forward fan 14, effectively recovering the counterclockwise airflow. The rotational kinetic energy of the airflow from fan 10 is converted into a stronger, direct wind, which generates higher wind pressure. This forces the air to penetrate the entire heat dissipation fins 16 more evenly and powerfully. The relatively cool air comes into contact with the high-temperature heat dissipation fins 16, and the heat is carried away through convection. The higher wind pressure greatly enhances this convective heat transfer efficiency, significantly improving the heat dissipation effect. After the heat is carried away by the air, the temperature of the hydraulic oil flowing through the oil pipe 21 is significantly reduced, and then it is sent back to the oil tank of the hydraulic system. After a long period of work, the operator can activate multiple ultrasonic transducers 24. The mechanical waves generated by these transducers can enter the oil through the cleaning clips 23 and the oil pipes 21, forming an acoustic flow and generating tiny cavitation bubbles. This can destroy the adhesion of dirt while also enhancing the turbulence of the oil, thereby achieving non-contact continuous cleaning and enhanced heat transfer, greatly extending the cleaning cycle of the equipment and improving work efficiency.

[0033] The technological advancements achieved by this invention compared to existing technologies are: it allows air to penetrate the heat dissipation fins 16 more evenly and powerfully, greatly enhancing convective heat transfer efficiency; and it enables online cleaning without shutdown or disassembly, reducing downtime for cleaning and ensuring continuous and efficient operation of the equipment.
