Description

Technical Field

[0001] The invention relates to the technical field of cooling systems, and in particular to a gas medium circulation cooling system. Background Art

[0002] In industrial production activities, the parts of industrial equipment will generate a lot of heat, which will cause the temperature of the parts to rise, thus affecting the normal operation of the industrial equipment, and in severe cases, causing damage to the industrial equipment. Therefore, in order to ensure the normal and orderly progress of production activities, the parts need to be cooled.

[0003] At present, there are two main cooling methods for parts: air cooling and liquid cooling. The heat dissipation effect of air cooling is limited and it is difficult to meet the cooling requirements of high-power industrial equipment. Therefore, the cooling of high-power industrial equipment is mainly achieved through liquid cooling. However, there are some significant problems with the existing liquid cooling system.

[0004] First, most liquid cooling systems use a circulating pump to circulate the liquid cooling medium in the pipeline. This design means that the interface of the pipeline often needs to withstand the high-frequency pressure fluctuations caused by the circulating pump transporting the liquid cooling medium. This pressure fluctuation will cause continuous stress on the pipeline interface, thereby increasing the risk of leakage at the pipeline interface. In the long run, this will not only affect the cooling effect of the system, but may also cause coolant leakage, causing safety hazards and environmental pollution.

[0005] Secondly, existing liquid cooling systems are often complex in structure and difficult to maintain. The power components in the system, such as the circulating pump, require regular maintenance, which increases the operating cost and downtime of the system. This not only reduces production efficiency, but also increases the operating costs of the enterprise. At the same time, the complex system structure also increases the probability of failure and reduces the reliability of the system. In some industrial environments that require high stability, this reduction in reliability may have serious consequences. Summary of the invention

[0006] The object of the present invention is to provide a gas medium circulating cooling system, which has the advantages of simple structure, convenient maintenance, good cooling effect and low risk of leakage of liquid cooling medium.

[0007] The technical solution of the present invention to solve the above technical problems is: a gas medium circulation cooling system, including a liquid medium cavity arranged on the lower surface close to the heat generating element, a gaseous medium cavity connected to the liquid medium cavity is provided above the liquid medium cavity, and the upper part of the gaseous medium cavity is connected to the input end of a gradual gas cooling device through a gaseous medium output pipe, the output end of the gradual gas cooling device is directly connected to the gaseous medium cavity through the gaseous medium input pipe, and the output end of the gaseous medium input pipe is located below the input end of the gaseous medium output pipe.

[0008] As a further improvement of the present invention, the liquid medium cavity and the gaseous medium cavity are an integrated cavity, and a grid plate is horizontally provided between the liquid medium cavity and the gaseous medium cavity to separate the two.

[0009] As a further improvement of the present invention, a liquid level sensor is provided on the inner wall of the liquid medium cavity.

[0010] As a further improvement of the present invention, the gaseous medium cavity and the input end of the gradual gas cooling device are both quickly connected to the end of the gaseous medium output pipe through a quick connector.

[0011] As a further improvement of the present invention, the gaseous medium cavity and the output end of the gradual gas cooling device are both quickly connected to the end of the gaseous medium input pipe through a quick connector.

[0012] As a further improvement of the present invention, a heat-conducting material is filled between the lower surface of the liquid medium cavity and the heating element.

[0013] As a further improvement of the present invention, a heat-conducting material is filled between the lower surface of the liquid medium cavity and the heating element.

[0014] Beneficial Effects

[0015] Compared with the prior art, the advantages of a gas medium circulation cooling system of the present invention are:

[0016] 1. The circulating cooling system includes a liquid medium cavity whose lower surface is close to the heating element, a gaseous medium cavity connected to the liquid medium cavity is provided above the liquid medium cavity, and the upper part of the gaseous medium cavity is connected to the input end of the gradual gas cooling device through a gaseous medium output pipe, and the output end of the gradual gas cooling device is directly connected to the gaseous medium cavity through the gaseous medium input pipe, and the output end of the gaseous medium input pipe is located below the input end of the gaseous medium output pipe;

[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Example:

[0026] In industrial production activities, parts and components in industrial equipment will generate a lot of heat, which will cause the temperature of parts and components to rise, thereby affecting the normal operation of industrial equipment, and in severe cases, causing damage to industrial equipment. Therefore, in order to ensure the normal and orderly progress of production activities, it is necessary to cool the parts and components. In the prior art, there are two main cooling methods for parts and components: air cooling and liquid cooling. Among them, the heat dissipation effect of air cooling is limited, and it is difficult to meet the cooling requirements of high-power industrial equipment. Therefore, the cooling of high-power industrial equipment is mainly achieved by liquid cooling. However, there are some problems with the current liquid cooling system. Most liquid cooling systems realize the circulation of liquid cooling medium in the pipeline by setting a circulating pump. This design causes the interface of the pipeline to often need to withstand the high-frequency pressure fluctuations caused by the circulating pump conveying liquid cooling medium. This pressure fluctuation will cause continuous stress on the pipeline interface, thereby increasing the risk of leakage at the pipeline interface. Once the liquid cooling medium leaks, it often causes serious corrosion to the parts and components. Another problem is that the existing liquid cooling system is often complex in structure and difficult to maintain. The power components such as the circulating pump in the system need to be maintained regularly, which increases the operating cost and downtime of the system. Meanwhile, the complex system structure also increases the probability of failure and reduces the reliability of the system. In view of these problems, the present invention proposes a gas medium circulation cooling system.

[0027] The specific embodiments of the present invention are as follows Figure 1 As shown, a gas medium circulation cooling system includes a liquid medium cavity 1 whose lower surface is arranged close to the heating element 9. A gaseous medium cavity 2 is arranged above the liquid medium cavity 1 and is connected thereto, and the upper part of the gaseous medium cavity 2 is connected to the input end of the gradual gas cooling device 6 through the gaseous medium output pipe 3. The output end of the gradual gas cooling device 6 is directly connected to the gaseous medium cavity 2 through the gaseous medium input pipe 4, and the output end of the gaseous medium input pipe 4 is located below the input end of the gaseous medium output pipe 3. In this embodiment, regarding the gradual gas cooling device 6, it is mainly used for grading and gradually cooling the gaseous cooling medium. The gradual gas cooling device 6 belongs to the prior art for those skilled in the art, and there are currently a variety of related equipment on the market that can meet the above description: such as a gas cooling tower, so its specific structure will not be elaborated in detail here.

[0028] During the implementation process, the liquid medium cavity 1 is set close to the heating element 8, and the heat generated by the heating element 8 is directly absorbed by the liquid cooling medium to achieve preliminary cooling. At the same time, the liquid cooling medium that absorbs heat and evaporates will be converted into a gaseous cooling medium, which will further absorb heat and enter the gaseous medium cavity 2. After that, the gaseous medium output pipe 3 transfers the high-temperature gaseous cooling medium to the gradual cooling device 6 for cooling treatment. The cooled gaseous cooling medium returns to the gaseous medium cavity 2 through the gaseous medium input pipe 4 to complete the cycle. The output end of the gaseous medium input pipe 4 is located below the input end of the gaseous medium output pipe 3 to ensure that the cooled gaseous cooling medium can flow back smoothly to form an effective circulating cooling system. The system realizes cooling of the heating element 8 through the liquid cooling medium, and takes away heat through the circulation of the gaseous cooling medium. Compared with the liquid cooling medium circulation in the prior art, the gaseous cooling medium circulation avoids the high-frequency pressure fluctuation problem caused by the circulating pump in the traditional liquid cooling system, and reduces the risk of leakage of the liquid cooling medium. At the same time, the system structure is relatively simple, which reduces the difficulty of maintenance and operating costs, and improves reliability.

[0029] Compared with the existing liquid cooling system, the gas medium circulation cooling system has the following advantages and innovations: the circulation of the gaseous cooling medium avoids the high-frequency pressure fluctuation problem caused by the circulation pump in the traditional liquid cooling system, and reduces the risk of leakage of the liquid cooling medium; the system structure is relatively simple, which reduces the maintenance difficulty and operating cost and improves reliability; the liquid medium cavity 1 is arranged close to the heating element 8, and the liquid cooling medium directly absorbs the heat generated by the heating element to achieve preliminary cooling, and the heat-absorbing and evaporated liquid cooling medium is converted into a gaseous cooling medium, which further absorbs heat and enters the gaseous medium cavity 2 to form an effective circulation cooling system.

[0030] In the system, the liquid medium cavity 1 and the gaseous medium cavity 2 are an integrated cavity, and a grid plate 7 is horizontally provided between the liquid medium cavity 1 and the gaseous medium cavity 2 to separate the two. Through this design, the liquid medium cavity 1 and the gaseous medium cavity 2 can be separated without affecting the liquid cooling medium evaporating into the gaseous cooling medium and then entering the gaseous medium cavity 2. In addition, the existence of the grid plate 7 itself can also have a certain anti-fluctuation effect on the liquid cooling medium, thereby reducing the large fluctuation of the liquid cooling medium caused by the vibration and shaking of the liquid medium cavity 1, thereby ensuring the smooth and orderly operation of the entire system.

[0031] In this embodiment, the grid plate 7 can be designed in a variety of ways. For example, the grid plate 7 can be made of metal material or high temperature resistant plastic material to ensure its stability in a high temperature environment. The aperture and arrangement of the grid plate 7 can be designed according to specific cooling requirements to achieve the best wave suppression effect. As a preferred embodiment, the grid plate 7 can be designed with staggered small holes, which can further enhance the effect of suppressing the fluctuation of the liquid cooling medium.

[0032] At the same time, a liquid level sensor 11 is provided on the inner wall of the liquid medium cavity 1 of the system. The liquid level sensor 11 is used to monitor the liquid level height of the liquid cooling medium in real time, so as to ensure that the liquid level in the liquid medium cavity 1 is maintained within an appropriate range. By providing the liquid level sensor 11, the shortage or excess of the liquid cooling medium can be detected in time, and the problem of poor cooling effect caused by too little liquid cooling medium or overflow caused by too much liquid cooling medium can be prevented. The application of the liquid level sensor 11 effectively improves the reliability and safety of the system and ensures the normal operation of the cooling system.

[0033] In this embodiment, the liquid level sensor 11 can be implemented by a variety of technologies, such as an ultrasonic liquid level sensor, a capacitive liquid level sensor or a float liquid level sensor. 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 the corrosion of the liquid cooling medium to the sensor through a non-contact measurement method, thereby extending the service life of the sensor.

[0034] In addition, the gaseous medium cavity 2 and the input end of the gradual gas cooling device 6 are both quickly connected to the end of the gaseous medium output pipe 3 through a quick connector 5. By using the quick connector 5, the quick connection and disassembly between the gaseous medium cavity 2, the input end of the gradual cooling device 6 and the gaseous medium output pipe 3 are achieved, simplifying the operation of the system. The application of the quick connector 5 makes it easier to disassemble and reassemble the system when maintenance or replacement of parts is required, thereby improving the maintenance efficiency and reliability of the system. Through the application of the quick connector 5, the problem of inconvenient connection and disassembly between the gas medium cavity 2 and the gradual cooling device 6 is solved, and the convenience of operation and maintenance efficiency of the system are improved.

[0035] In this embodiment, the quick connector 5 can be implemented in a variety of ways. For example, a snap-on quick connector can be used to achieve quick connection and disassembly by fixing and releasing the snap; a threaded quick connector can also be used to achieve connection and disassembly by rotating the thread. In addition, the material selection of the quick connector 5 can be based on the needs of the specific application scenario, and high temperature resistant and corrosion resistant materials can be selected to ensure the reliability and durability of the connection. Furthermore, in order to improve the sealing of the connection, a sealing ring can be set at the connection part of the quick connector 5 to prevent leakage of the gaseous cooling medium.

[0036] In addition, the gaseous medium cavity 2 and the output end of the gradual gas cooling device 6 are both quickly connected to the end of the gaseous medium input pipe 4 through a quick connector 5. This design makes the connection and disassembly of the system more convenient. By adopting the quick connector 5, the time for system maintenance and overhaul can be reduced, and the operating efficiency and reliability of the system can be improved. The application of the quick connector 5 can effectively solve the problems of high operating costs and long downtime caused by complex structures and difficult maintenance in traditional liquid cooling systems.

[0037] In this embodiment, the quick connector 5 can adopt a variety of structural forms, such as a snap-on type, a rotary locking type, or a push-pull type connection structure. These structural forms can realize the quick connection and disassembly of the gaseous medium cavity 2 and the output end of the gradual cooling device 6, and adapt to different use 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 should be noted that:

[0039] A heat-conducting material 12 is filled between the lower surface of the liquid medium cavity 1 and the heating element 8. By filling the heat-conducting material 12 between the lower surface of the liquid medium cavity 1 and the heating element 8, the efficiency of heat transfer from the heating element 8 to the liquid cooling medium is enhanced. The function of the heat-conducting material 12 is to accelerate the transfer of heat, thereby improving the overall heat dissipation effect of the cooling system. This solution improves the heat conduction efficiency by adding heat-conducting materials, solving the problem of how to improve the heat conduction efficiency of the gas cooling medium circulation cooling system.

[0040] The heat-conducting material 12 can be made of metal materials with high thermal conductivity, such as copper, aluminum, etc., or non-metallic materials with excellent thermal conductivity, such as graphene, carbon nanotubes, etc. Specifically, the heat-conducting material 12 should have good thermal conductivity and mechanical properties, be stable in a high temperature environment, and have good compatibility with the liquid cooling medium and the heating element 8. For example, a layer of thermal conductive paste can be coated on the lower surface of the liquid medium cavity 1, or a thermal 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 best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
