Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically to a pull-out type cooling structure. Background Technology

[0002] In the field of industrial equipment cooling, traditional cooling structures often require drilling or welding on the equipment surface for installation. This secondary processing not only compromises the structural integrity of the equipment but can also shorten its lifespan due to stress concentration. While the currently mainstream pressurized water pipe cooling structure can achieve media circulation, the air gap between the water pipe and the equipment surface results in high thermal resistance at the contact surface, affecting heat dissipation efficiency. Furthermore, thermally conductive silicone grease is commonly used to fill gaps between the cooling plate and the equipment to improve contact; however, once the grease hardens, it makes disassembly difficult, requiring time-consuming cleaning of residues during maintenance, severely impacting equipment repair efficiency. These technical bottlenecks significantly restrict the overall performance and ease of use of cooling systems, urgently requiring breakthroughs through structural innovation. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems by providing a pull-type installation cooling structure. Through the design of double-sided pull-type cooling plates and extended assembly area, it achieves non-destructive installation on the equipment surface, and double-sided clamping can be completed without secondary processing. The rigid connection structure of the pull screws remains stable under vibration conditions. The cooling tank directly contacts the equipment surface to form a direct heat conduction interface, which reduces contact thermal resistance compared to traditional press-in water pipes. Combined with the gradient heat dissipation layout of multi-stage cooling plates in series, the overall heat dissipation efficiency is improved.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A pull-type mounting cooling structure includes oppositely arranged cooling plates that can be mounted on both sides of a target device. Each cooling plate includes a cooling area matching the target device and an assembly area extending outward from the target device. Pairs of assembly areas are respectively located on both sides of the cooling area, and mounting holes are provided at the assembly areas. The structure also includes pull rods that can match the mounting holes. The two ends of the pull rods can respectively match the mounting holes on the two opposite cooling plates, connecting the assembly areas of the paired cooling plates. A cooling groove is provided on the side of the cooling area matching the target device. The cooling plate also has a cooling medium inlet and a cooling medium outlet that connect the cooling groove to the external environment. The cooling medium can flow into the cooling groove from the cooling medium inlet and flow out of the cooling groove from the cooling medium outlet.

[0006] Thanks to the above technical solutions, the equipment is installed simultaneously on both sides by using relatively arranged cooling plates and tie rod structures. The extended assembly area design eliminates the need to drill connection holes on the equipment body during installation, avoiding damage to the equipment during secondary processing. The cooling medium directly contacts the equipment surface through the cooling tank for heat transfer, effectively reducing thermal resistance compared to the traditional pressurized water pipe structure. The cooling tank, cooling medium inlet, and cooling medium outlet work together to form a cooling path, achieving efficient and continuous cooling of the target equipment.

[0007] Furthermore, an inlet pipe is provided at the cooling medium inlet, and an outlet pipe is provided at the cooling medium outlet. One end of the inlet pipe extends into the cooling medium inlet and is sealed to the cooling medium inlet, while the other end of the inlet pipe extends out of the cooling medium inlet. One end of the outlet pipe extends into the cooling medium outlet and is sealed to the cooling medium outlet, while the other end of the outlet pipe extends out of the cooling medium outlet.

[0008] Thanks to the above technical solutions, the double-extended pipeline structure ensures the sealing of the medium transport, effectively preventing media leakage, and also enables convenient connection with external equipment; the segmented pipeline design facilitates maintenance and replacement.

[0009] Furthermore, the cooling plates are arranged in series with opposite sides, with the inlet pipe of one cooling plate connected to a cooling medium source and the outlet pipe connected to the inlet pipe of another cooling plate via a connecting pipe, and the outlet pipe of the other cooling plate connected to a cooling medium processing device.

[0010] Thanks to the above technical solutions, the series-connected cooling plates form a multi-stage cooling circuit, which can absorb heat from different parts of the equipment in a gradient manner; the optimized design of the medium circulation path significantly improves cooling efficiency; and the connecting pipe structure enables modular expansion to meet the distributed cooling needs of high-power equipment.

[0011] Furthermore, the end of the connecting pipe is connected to an inlet pipe or an outlet pipe via a pipe fitting.

[0012] Thanks to the above technical solutions, the detachable pipe joint design facilitates rapid system assembly and partial maintenance, and the standard interface specifications are compatible with various pipe specifications, improving system adaptability; the pipe joint can achieve a sealed connection, ensuring stable pressure during media transportation.

[0013] Furthermore, the cooling plate is also provided with a sealing part, which is arranged around the cooling groove.

[0014] Thanks to the above technical solution, the surrounding seal effectively prevents the leakage of cooling medium and ensures stable sealing performance under high temperature and high vibration conditions.

[0015] Furthermore, the sealing part includes a sealing groove disposed on the cooling plate and a sealing ring that matches the sealing groove, wherein the sealing ring protrudes at least partially from the sealing groove.

[0016] Thanks to the above technical solution, the convex design of the embedded sealing ring enhances the contact pressure compensation capability, ensuring that the cooling plate can still maintain an effective seal when the target equipment is vibrating during operation.

[0017] Furthermore, the cooling medium source includes a liquid cooling source and an air cooling source, which are connected to the cooling medium inlet of the cooling plate via a three-way valve.

[0018] Thanks to the aforementioned technical solution, the three-way valve achieves dual-mode switching between air cooling and liquid cooling. When the target device is operating, it can be connected to a liquid cooling source for heat dissipation. When the target device is shut down, the liquid cooling source can be turned off and the air cooling source connected. This serves two purposes: firstly, it removes residual coolant from the cooling chamber, preventing contamination or damage to the target device during cooling plate removal; secondly, it removes excess heat from the target device, extending its lifespan. In some low-power scenarios, air cooling can also be directly selected to cool the target device as needed.

[0019] Furthermore, the three-way valve is a solenoid valve, which is signal-connected to the control device and is controlled by the control device.

[0020] Thanks to the above technical solution, the signal connection between the solenoid valve and the control device has been automated, which can automatically switch the cooling mode according to the real-time operating conditions, reduce human operation errors, and improve the system response speed and operational stability.

[0021] Furthermore, the target device is a vacuum pump, which is signal-connected to a control device. The control device can control the three-way valve according to the working state of the vacuum pump. The air cooling source includes a nitrogen purging module configured inside the vacuum pump. When the vacuum pump performs gas compression, the three-way valve is connected to the liquid cooling source and closed to the air cooling source. When the vacuum pump stops air compression and performs purging, the three-way valve is connected to the air cooling source and closed to the liquid cooling source.

[0022] Thanks to the aforementioned technical solution, the vacuum pump's operating status and cooling mode are intelligently linked. Liquid cooling is activated during the compression phase to ensure efficient heat dissipation, while gas cooling is switched during the purging phase to prevent coolant residue. Furthermore, airflow purging further enhances the heat dissipation effect. The reuse of the vacuum pump's built-in nitrogen purging module simplifies the system structure and enables a self-cleaning function when the vacuum pump stops.

[0023] Furthermore, the air cooling source includes a nitrogen purging module configured inside the vacuum pump and an external air source, and the three-way valve is connected to the gas purging module and the external air source respectively through a three-way pipe.

[0024] Thanks to the above technical solution, the three-way pipe structure provides dual protection with both built-in and external gas sources. When the vacuum pump is not using the nitrogen purging module, it can automatically switch to the external gas source to ensure the purging process continues stably and improves the reliability of the system operation.

[0025] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: Through the design of double-sided counter-pull cooling plates and extended assembly areas, non-destructive installation of the equipment surface is achieved, and double-sided clamping can be completed without secondary processing. The rigid connection structure of the counter-pull screws remains stable under vibration conditions. The cooling tank directly contacts the equipment surface to form a direct heat conduction interface, reducing contact thermal resistance compared to traditional pressurized water pipes. Combined with the gradient heat dissipation layout of multi-stage cooling plates in series, the overall heat dissipation efficiency is improved. A three-way valve is used for dual-mode intelligent switching, enabling efficient liquid cooling during the target equipment operation phase and switching to air cooling to remove residual liquid and purge residual heat during shutdown. A redundant air supply system is formed by utilizing the reused nitrogen purging module of the vacuum pump and an external air source to ensure a stable supply of cooling medium. An elastic sealing ring replaces thermally conductive silicone grease to achieve self-sealing, eliminating the need to clean solidified residues during disassembly. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1

[0034] A pull-out type cooling structure, such as Figures 1-4 As shown, the device includes opposing cooling plates 11, which can be mounted on both sides of the target device 6. Each cooling plate 11 includes a cooling area matching the target device 6 and an assembly area extending outward from the target device 6. Pairs of assembly areas are respectively located on both sides of the cooling area, and each assembly area has mounting holes. The device also includes tie rods 7 that can match the mounting holes. The two ends of the tie rods 7 can respectively match the mounting holes on the two opposing cooling plates 11, connecting the assembly areas of the paired cooling plates 11. The number of mounting holes is set as needed and is not limited here. In this embodiment, each assembly area has two mounting holes side by side, meaning that the two opposing assembly areas are connected by two tie rods 7. A total of four tie rods 7 cooperate to restrict the two opposing cooling plates 11 to both sides of the target device. The dual-sided cooling plates 11 can be flexibly installed in any area of ​​the target device 6 that can support a clamping structure, according to requirements. Figure 1 The diagram only shows the pair of cooling plates 11 located at the top and bottom of the target device 6. In addition, the pair of cooling plates 11 can also be located at the left and right ends, front and rear ends, etc. of the target device 6.

[0035] The cooling zone is provided with a cooling tank 103 on the side that matches the target device 6. The cooling plate 11 is also provided with a cooling medium inlet 101 and a cooling medium outlet 102 that connect the cooling tank 103 to the external environment. The cooling medium can flow into the cooling tank 103 from the cooling medium inlet 101 and out of the cooling tank 103 from the cooling medium outlet 102. The cooling tank 103 has a long strip structure. The cooling medium inlet 101 and the cooling medium outlet 102 are respectively located on both sides of the length of the cooling tank 103. Both the cooling medium inlet 101 and the cooling medium outlet 102 are connecting holes opened from the side wall of the cooling plate into the cooling tank 103.

[0036] Specifically, the equipment is installed simultaneously on both sides by the relatively arranged cooling plate 11 and the tie rod 7. The extended assembly area design eliminates the need to drill connection holes on the equipment body during installation, avoiding damage to the equipment during secondary processing. The cooling medium directly contacts the equipment surface through the cooling tank 103 for heat transfer, which effectively reduces thermal resistance compared to the traditional pressurized water pipe structure. The cooling tank 103, the cooling medium inlet 101, and the cooling medium outlet 102 work together to form a cooling path, achieving efficient and continuous cooling of the target equipment 6.

[0037] An inlet pipe 1 is provided at the cooling medium inlet 101, and an outlet pipe 3 is provided at the cooling medium outlet 102. One end of the inlet pipe 1 extends into the cooling medium inlet 101 and is sealed to the cooling medium inlet 101. The sealing connection method is not limited and can be welding, gluing, etc. The other end of the inlet pipe 1 extends out of the cooling medium inlet 101. One end of the outlet pipe 3 extends into the cooling medium outlet 102 and is sealed to the cooling medium outlet 102. The other end of the outlet pipe 3 extends out of the cooling medium outlet 102.

[0038] Specifically, the double-extended pipeline structure ensures the sealing of the medium transport, effectively preventing media leakage, and also enables convenient connection with external equipment; the segmented pipeline design facilitates maintenance and replacement.

[0039] The cooling plates 11 are arranged in series with opposite sides. The inlet pipe 1 of one cooling plate 11 is connected to the cooling medium source, and the outlet pipe 3 is connected to the inlet pipe 1 of another cooling plate 11 through the connecting pipe 9. The outlet pipe 3 of the other cooling plate 11 is connected to the cooling medium treatment device. The cooling medium treatment device can be a waste liquid tank or a purification and circulation device. The cooling medium treatment device is not shown in the figure.

[0040] Specifically, the series-connected cooling plates 11 form a multi-stage cooling circuit, which can absorb heat from different parts of the equipment in a gradient manner; the optimized design of the medium circulation path significantly improves the cooling efficiency; and the connecting pipe 9 structure enables modular expansion to meet the distributed cooling needs of high-power equipment.

[0041] The end of the connecting pipe 9 is connected to the inlet pipe 1 or the outlet pipe 3 via the pipe fitting 8. That is, the two ends of the connecting pipe 9 are respectively connected to the inlet pipe 1 of one cooling plate 11 and the outlet pipe of the other cooling plate 11 via the pipe fitting 8.

[0042] Specifically, the detachable pipe fitting 8 is designed to facilitate rapid system assembly and partial maintenance, and its standard interface specifications are compatible with various pipe specifications, improving system adaptability; the pipe fitting 8 can achieve a sealed connection, ensuring stable pressure during media transportation.

[0043] The cooling plate 11 is also provided with a sealing part 104, which is arranged around the cooling groove 103.

[0044] Specifically, the surrounding seal 104 effectively prevents the leakage of cooling medium and ensures stable sealing performance under high temperature and high vibration conditions.

[0045] The sealing part 104 includes a sealing groove provided on the cooling plate 11 and a sealing ring 10 that matches the sealing groove, wherein the sealing ring 10 protrudes at least partially from the sealing groove.

[0046] Specifically, the convex design of the embedded sealing ring 10 enhances the contact pressure compensation capability, ensuring that the cooling plate 11 remains effectively sealed even when the target device 6 is vibrating during operation.

[0047] The cooling medium source includes a liquid cooling source and an air cooling source, which are connected to the cooling medium inlet 101 of the cooling plate 11 via a three-way valve 2.

[0048] Specifically, the three-way valve 2 enables dual-mode switching between air cooling and liquid cooling. When the target device 6 is operating, it can be connected to the liquid cooling source for liquid cooling heat dissipation. When the target device 6 is turned off, the liquid cooling source can be turned off and the air cooling source can be connected. This serves two purposes: firstly, it removes residual coolant from the cooling chamber, preventing residual coolant from contaminating or damaging the target device 6 during the disassembly of the cooling plate 11; secondly, it removes residual heat from the target device 6, extending its service life. In some low-power scenarios, the target device 6 can also be cooled directly using the air cooling source as needed.

[0049] The three-way valve 2 is a solenoid valve, which is connected to the control device via a signal and is controlled by the control device.

[0050] Specifically, the signal connection between the solenoid valve and the control device enables automated control, which can automatically switch the cooling mode according to real-time operating conditions, reducing human operation errors and improving system response speed and operational stability.

[0051] The target device 6 is a vacuum pump, which is signal-connected to a control device. The control device can control the three-way valve 2 according to the working status of the vacuum pump. The air cooling source includes a nitrogen purging module configured inside the vacuum pump. When the vacuum pump performs gas compression, the three-way valve 2 is connected to the liquid cooling source and closed to the air cooling source. When the vacuum pump stops air compression and performs purging, the three-way valve 2 is connected to the air cooling source and closed to the liquid cooling source.

[0052] Specifically, the vacuum pump's operating status is intelligently linked to its cooling mode. Liquid cooling is activated during the compression phase to ensure efficient heat dissipation, while gas cooling is switched during the purging phase to prevent coolant residue. Simultaneously, airflow purging further enhances heat dissipation. The reuse of the vacuum pump's built-in nitrogen purging module simplifies the system structure and enables a self-cleaning function when the vacuum pump stops.

[0053] The air cooling source includes a nitrogen purging module configured inside the vacuum pump and an external air source. The three-way valve 2 is connected to the gas purging module and the external air source respectively through a three-way pipe 4.

[0054] Specifically, the three-way pipe 4 structure provides dual protection with both built-in and external gas sources. When the vacuum pump is not using the nitrogen purging module, it can automatically switch to the external gas source to ensure the purging process continues stably and improves the reliability of system operation.

[0055] During installation, first, attach the paired cooling plates 11 to both sides of the target equipment 6 and tighten them by pulling the tie rods 7 through the mounting holes in the assembly area. Make the sealing ring 10 contact the vacuum pump, and the sealing part 104, cooling tank 103, and vacuum pump cooperate to form a cooling chamber. Then, use the connecting pipe 9 and pipe fitting 8 to connect the two cooling plates 11 in series. Connect the inlet pipe 1 of the upper cooling plate 11 to the three-way valve 2. The three-way valve 2 is then connected to the liquid cooling source and one end of the three-way pipe 4. The remaining end of the three-way pipe 4 is connected to the nitrogen purging module inside the vacuum pump via the connector 5. The other end of the three-way pipe 4 is connected to an external gas source, meaning the gas cooling source includes the nitrogen purging module and the external gas source.

[0056] When the vacuum pump starts, the control device switches the three-way valve 2 to connect to the liquid cooling source, and the coolant directly absorbs the heat of the pump body through the cooling tank 103; after the vacuum pump stops, the control device switches the three-way valve 2 to connect to the gas cooling source, and the nitrogen purging module or external gas source delivers airflow to the cooling chamber to remove residual coolant and discharge residual heat.

[0057] When disassembly is required, the cooling plate 11 can be directly separated after removing the tie rod 7. The sealing ring 10 will automatically reset and detach from the contact surface, without the need to clean the cured silicone grease.
