Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling system technology, and in particular to a gas medium circulating cooling system. Background Technology
[0002] In industrial production, the components of industrial equipment generate a large amount of heat. This heat can cause the component temperatures to rise, affecting the normal operation of the industrial equipment and, in severe cases, leading to damage. Therefore, to ensure the normal and orderly progress of production activities, it is necessary to cool the components.
[0003] Currently, the main cooling methods for components are air cooling and liquid cooling. Air cooling has limited heat dissipation effect and is difficult to meet the cooling requirements of high-power industrial equipment. Therefore, liquid cooling is mainly used to cool high-power industrial equipment. However, existing liquid cooling systems have some significant problems.
[0004] First, most liquid cooling systems use circulating pumps to circulate the liquid coolant through the pipes. This design means that the pipe joints often have to withstand high-frequency pressure fluctuations caused by the pump delivering the coolant. These pressure fluctuations create continuous stress on the pipe joints, increasing the risk of leaks. In the long run, this not only affects the system's cooling performance but can also lead to coolant leaks, causing safety hazards and environmental pollution.
[0005] Secondly, existing liquid cooling systems are often complex in structure and difficult to maintain. Power components such as the circulating pumps require regular maintenance, increasing operating costs and downtime. This not only reduces production efficiency but also increases the company's operating costs. Simultaneously, the complex system structure increases the probability of failure and reduces system reliability. In some industrial environments requiring high stability, this reduction in reliability can have serious consequences. Utility Model Content

[0016] 1.

[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings.
[0025] Example:
[0026] In industrial production, components in industrial equipment generate a significant amount of heat, which can cause their temperatures to rise, affecting the normal operation of the equipment and potentially leading to damage. Therefore, cooling is essential to ensure the smooth operation of production. Currently, the main cooling methods for components are air cooling and liquid cooling. However, air cooling has limited heat dissipation and is insufficient for high-power industrial equipment. Therefore, liquid cooling is primarily used for cooling high-power industrial equipment. However, current liquid cooling systems have several problems. Most liquid cooling systems use circulating pumps to circulate the liquid coolant in the pipes. This design means that the pipe joints often have to withstand high-frequency pressure fluctuations caused by the circulating pump. These pressure fluctuations create continuous stress on the pipe joints, increasing the risk of leaks. Leaks of liquid coolant often cause severe corrosion to the components. Another problem is that existing liquid cooling systems are often complex in structure and difficult to maintain. Power components such as the circulating pump require regular maintenance, increasing operating costs and downtime. Meanwhile, the complex system structure also increases the probability of failure and reduces the system's reliability. To address these issues, this invention proposes a gas medium circulating cooling system.
[0027] The specific embodiments of this utility model are as follows: Figure 1 As shown, a gaseous medium circulating cooling system includes a liquid medium chamber 1 with its lower surface closely attached to a heating element 9. A gaseous medium chamber 2 is located above and communicates with the liquid medium chamber 1, and the upper part of the gaseous medium chamber 2 is connected to the input end of a gradual gas cooling device 6 via a gaseous medium output pipe 3. The output end of the gradual gas cooling device 6 is directly connected to the gaseous medium chamber 2 via a gaseous medium input pipe 4, with the output end of the gaseous medium input pipe 4 located below the input end of the gaseous medium output pipe 3. In this embodiment, the gradual gas cooling device 6 is mainly used for graded and gradual cooling of the gaseous cooling medium. The gradual gas cooling device 6 is prior art to those skilled in the art, and there are currently many related devices on the market that can meet the above description, such as gas cooling towers; therefore, its specific structure will not be described in detail here.
[0028] In the process, the liquid medium chamber 1 is positioned close to the heating element 8, directly absorbing the heat generated by the heating element 8 through the liquid cooling medium, achieving initial cooling. Simultaneously, the heat-absorbing and evaporating liquid cooling medium transforms into a gaseous cooling medium, further absorbing heat and entering the gaseous medium chamber 2. Then, the gaseous medium output pipe 3 transfers the high-temperature gaseous cooling medium to the gradual cooling device 6 for further cooling. The cooled gaseous cooling medium returns to the gaseous medium chamber 2 through the gaseous medium input pipe 4, completing the circulation. The output end of the gaseous medium input pipe 4 is located below the input end of the gaseous medium output pipe 3, ensuring smooth return of the cooled gaseous cooling medium and forming an effective circulating cooling system. This system cools the heating element 8 through the liquid cooling medium and removes heat through the circulation of the gaseous cooling medium. Compared to existing liquid cooling medium circulation technologies, gaseous cooling medium circulation avoids the high-frequency pressure fluctuations caused by the circulating pump in traditional liquid cooling systems, reducing the risk of liquid cooling medium leakage. Furthermore, the system structure is relatively simple, reducing maintenance difficulty and operating costs, and improving reliability.
[0029] Compared with existing liquid cooling systems, this gaseous medium circulation cooling system has the following advantages and innovations: The circulation of the gaseous cooling medium avoids the high-frequency pressure fluctuations caused by the circulation pump in traditional liquid cooling systems, reducing the risk of liquid cooling medium leakage; the system structure is relatively simple, reducing maintenance difficulty and operating costs, and improving reliability; the liquid medium chamber 1 is set close to the heat-generating element 8, directly absorbing the heat generated by the heat-generating element through the liquid cooling medium to achieve initial cooling. The heat-absorbing and evaporating liquid cooling medium is converted into a gaseous cooling medium, further absorbing heat and entering the gaseous medium chamber 2, forming an effective circulation cooling system.
[0030] In this system, the liquid medium chamber 1 and the gaseous medium chamber 2 are integrated into one cavity, and a horizontal grid plate 7 is provided between them to separate them. This design achieves separation between the liquid medium chamber 1 and the gaseous medium chamber 2 without affecting the entry of the liquid cooling medium into the gaseous medium chamber 2 after evaporation into gaseous cooling medium. Furthermore, the presence of the grid plate 7 itself also has a certain effect on suppressing the fluctuations of the liquid cooling medium, thereby reducing large fluctuations caused by vibration and swaying of the liquid medium chamber 1, and ensuring the stable and orderly operation of the entire system.
[0031] In this embodiment, the design of the grating plate 7 can be varied. For example, the grating plate 7 can be made of metal or high-temperature resistant plastic to ensure its stability in high-temperature environments. The aperture and arrangement of the grating plate 7 can be designed according to specific cooling requirements to achieve the best wave suppression effect. As a preferred embodiment, the grating plate 7 can adopt a staggered arrangement of small holes, which can further enhance the suppression effect on the fluctuation of the liquid cooling medium.
[0032] Meanwhile, a liquid level sensor 11 is installed on the inner wall of the liquid medium chamber 1 of the system. The liquid level sensor 11 is used to monitor the liquid level of the liquid cooling medium in real time, thereby ensuring that the liquid level in the liquid medium chamber 1 is maintained within an appropriate range. By setting up the liquid level sensor 11, insufficient or excessive liquid cooling medium can be detected in a timely manner, preventing poor cooling effect due to insufficient liquid cooling medium or overflow problems caused by excessive liquid cooling medium. The application of the liquid level sensor 11 effectively improves the reliability and safety of the system, ensuring the normal operation of the cooling system.
[0033] In this embodiment, the liquid level sensor 11 can be implemented using various technologies, such as ultrasonic liquid level sensors, capacitive liquid level sensors, or float-type liquid level sensors. These sensors detect the liquid level height through different working principles and transmit the signal to the control system for real-time monitoring. As a preferred embodiment, the ultrasonic liquid level sensor can avoid corrosion of the sensor by the liquid cooling medium through a non-contact measurement method, thereby extending the service life of the sensor.
[0034] Furthermore, both the gaseous medium chamber 2 and the input end of the gradual gas cooling device 6 are quickly connected to the end of the gaseous medium output pipe 3 via quick-connect couplings 5. By using quick-connect couplings 5, rapid connection and disconnection between the gaseous medium chamber 2, the input end of the gradual cooling device 6, and the gaseous medium output pipe 3 are achieved, simplifying system operation. The application of quick-connect couplings 5 makes it easier to disassemble and reassemble the system when maintenance or component replacement is required, thereby improving system maintenance efficiency and reliability. The application of quick-connect couplings 5 solves the problem of inconvenient connection and disconnection between the gaseous medium chamber 2 and the gradual cooling device 6, improving the system's operational convenience and maintenance efficiency.
[0035] In this embodiment, the quick connector 5 can be implemented in various ways. For example, a snap-on quick connector can be used, achieving quick connection and disassembly through the fixing and releasing of the snap; a threaded quick connector can also be used, achieving connection and disassembly by rotating the thread. Furthermore, the material selection for the quick connector 5 can be based on the specific application requirements, choosing high-temperature resistant and corrosion-resistant materials to ensure the reliability and durability of the connection. Further, to improve the sealing performance of the connection, a sealing ring can be provided at the connection point of the quick connector 5 to prevent leakage of gaseous cooling media.
[0036] Furthermore, both the gaseous medium chamber 2 and the output end of the gradual gas cooling device 6 are quickly connected to the end of the gaseous medium input pipe 4 via quick-connect couplings 5. This design makes system connection and disassembly more convenient. By using quick-connect couplings 5, system maintenance and repair time can be reduced, improving system operating efficiency and reliability. The application of quick-connect couplings 5 can effectively solve the problems of high operating costs and long downtime caused by the complex structure and difficult maintenance of traditional liquid cooling systems.
[0037] In this embodiment, the quick connector 5 can adopt various structural forms, such as snap-fit, rotary locking, or push-pull connection structures. These structural forms can all achieve quick connection and disconnection between the gaseous medium chamber 2 and the output end of the gradient cooling device 6, adapting to different usage environments and requirements. Furthermore, the material of the quick connector 5 can be selected from high-temperature resistant and corrosion-resistant metals or high-strength plastics to ensure its reliability and durability in high-temperature or corrosive environments.
[0038] It is important to note that:
[0039] A thermally conductive material 12 is filled between the lower surface of the liquid medium cavity 1 and the heating element 8. By filling the space between the lower surface of the liquid medium cavity 1 and the heating element 8 with the thermally conductive material 12, the efficiency of heat transfer from the heating element 8 to the liquid cooling medium is enhanced. The function of the thermally conductive material 12 is to accelerate heat transfer, thereby improving the overall heat dissipation effect of the cooling system. This solution improves heat transfer efficiency by adding thermally conductive material, thus solving the problem of how to improve the heat transfer efficiency of a gas-cooled medium circulating cooling system.
[0040] The thermally conductive material 12 can be a high-thermal-conductivity metallic material, such as copper or aluminum, or a non-metallic material with excellent thermal conductivity, such as graphene or carbon nanotubes. Specifically, the thermally conductive material 12 should have good thermal conductivity and mechanical properties, be stable in high-temperature environments, and have good compatibility with the liquid cooling medium and the heating element 8. For example, a layer of thermally conductive paste can be coated on the lower surface of the liquid medium cavity 1, or a thermally conductive pad can be embedded to ensure that heat can be quickly transferred from the heating element 8 to the liquid cooling medium.
[0041] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
