It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0026] like Figures 1 to 3 As shown, the present application provides an automatic switch heat dissipation device based on soil source heat pump technology. An embodiment of the automatic switch heat dissipation device based on soil source heat pump technology includes: a heat exchange mechanism 1, a first conveying mechanism 2, a soil heat pipe mechanism 3, a reflux mechanism 4 and a second conveying mechanism 5. The interior of the heat exchange mechanism 1 is filled with a heat dissipation medium for heat exchange with the automatic switch 6. The first conveying mechanism 2 is used to convey the heat dissipation medium in the heat exchange mechanism 1. The soil heat pipe mechanism 3 is used to receive the heat dissipation medium conveyed by the first conveying mechanism 2 for heat dissipation and continue to convey. The reflux mechanism 4 is used to receive the heat dissipation medium after the soil heat pipe mechanism 3 has dissipated the heat and convey it after detecting whether the heat dissipation medium meets the requirements. The second conveying mechanism 5 is used to receive the heat dissipation medium conveyed by the reflux mechanism 4 and convey it to the heat exchange mechanism 1.

[0027] According to the technical solution of this embodiment, the heat exchange mechanism 1 is installed on the automatic switch 6. The heat exchange medium filled in the heat exchange mechanism 1 exchanges heat with the components of the automatic switch 6 to reduce its temperature. Then, the first conveying mechanism 2 conveys the heat exchanged heat exchange medium from the heat exchange mechanism 1 to the soil heat pipe mechanism 3, so that the heat exchange medium can achieve the effect of dissipating heat energy through heat exchange with the soil, and then conveys it to the return mechanism 4. After detection, if it meets the heat dissipation requirements, it is re-conveyed to the heat exchange mechanism 1 through the second conveying mechanism 5 to prepare for the next heat exchange; if it does not meet the heat dissipation requirements, the return mechanism 4 re-conveys the heat dissipation medium to the soil heat pipe mechanism 3 for secondary heat dissipation to meet the heat dissipation requirements. In this way, the method of realizing efficient heat dissipation through the low temperature characteristics of the underground soil uses the cold source in the natural environment to effectively conduct away the excess heat of the automatic switch 6, which is conducive to improving the heat dissipation efficiency, improving the heat dissipation effect, and ensuring the normal operation of the automatic switch 6. In addition, the above-mentioned heat dissipation medium can be heat exchanged with the soil at the location of the automatic switch 6, which is suitable for confined spaces or environments with high temperatures. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the use of forced air cooling and liquid cooling is limited in a closed space or a high temperature environment, resulting in poor heat dissipation effect of the automatic switch 6.

[0028] like Figures 1 to 3 As shown, the heat exchange mechanism 1 includes: a plurality of heat sinks 11, a first delivery pump 12 for delivering the heat dissipation medium in the plurality of heat sinks 11, and a first delivery pipe 13 corresponding to the first delivery pump 12; one end of the first delivery pipe 13 is respectively connected to the plurality of heat sinks 11, and the other end is connected to the first delivery mechanism 2; the first delivery pump 12 is arranged on one side of the first delivery pipe 13 close to the plurality of heat sinks 11. The direct contact between the plurality of heat sinks and the automatic switch element increases the surface area of ​​the heat exchange, thereby enhancing the absorption efficiency of the heat energy. The arrangement of the first delivery pump and the first delivery pipe ensures the stable circulation of the heat dissipation medium, so that the heat dissipation medium can effectively take away the heat generated by the automatic switch and prevent local overheating. The uniform distribution of the heat sink avoids the problem of uneven heat dissipation, improves the overall heat dissipation performance, ensures that the temperature of the automatic switch is within a safe range, thereby extending the service life of the switch and enhancing its reliability.

[0029] Specifically, Figure 1 to Figure 2As shown, a plurality of heat sinks 11 are arranged in a ring shape on the automatic switch 6 device, which achieves a better heat dissipation effect and avoids the situation where uneven arrangement on one side causes poor heat dissipation effect; the heat dissipation medium is filled in the heat sink 11, and when the heat dissipation medium in the heat sink 11 exchanges heat with the automatic switch 6 device and absorbs heat energy, it is transported to the first conveying pipe 13 through the first conveying pump 12 and enters the first conveying mechanism 2. After multi-stage heat dissipation and cooling, the heat dissipation medium is transported back to the heat sink 11 by the second conveying mechanism 5 for the next heat exchange; the optimized layout of the plurality of heat sinks 11 and the first conveying pump 12 greatly improves the heat dissipation performance, especially in high-load situations.

[0030] like Figures 1 to 3 As shown, the first conveying mechanism 2 includes: a first transfer tube 21 for receiving the heat dissipation medium of the heat exchange mechanism 1, a second delivery pump 22 for delivering the heat dissipation medium in the first transfer tube 21, and a second delivery pipe 23 corresponding to the second delivery pump 22; one end of the first transfer tube 21 is connected to the heat exchange mechanism 1, and the other end is connected to one end of the second delivery pipe 23; the other end of the second delivery pipe 23 is connected to the soil heat pipe mechanism 3; the second delivery pump 22 is arranged on the side of the second delivery pipe 23 close to the first transfer tube 21. The design of the first transfer tube can smoothly guide the heat dissipation medium from the heat exchange mechanism to the second delivery pipe, reducing the energy loss and flow resistance of the heat dissipation medium during the delivery process. The use of the second delivery pump ensures that the heat dissipation medium can overcome the pipeline resistance and be smoothly delivered to the soil heat pipe mechanism for the next step of heat dissipation, thereby optimizing the heat dissipation process of the entire system. The efficient connection of the first conveying mechanism with the heat exchange mechanism and the soil heat pipe mechanism forms a complete heat dissipation link, which improves the overall efficiency of the heat dissipation system.

[0031] Specifically, Figure 3 As shown, the heat dissipation medium delivered by the heat exchange mechanism 1 is received through the first transfer pipe 21, and the first transfer pipe 21 is set to a curved design to reduce flow resistance and have a smooth effect on it, thereby avoiding situations such as excessive flow causing pipeline blockage; when the heat dissipation medium passes through the second delivery pipe 23, it is delivered to the soil heat pipe mechanism 3 through the second delivery pump 22 for heat dissipation and cooling.

[0032] like Figures 1 to 3As shown, the soil heat pipe mechanism 3 includes: a second transfer pipe 31 for receiving the heat dissipation medium, a plurality of heat dissipation pipes 32 buried underground for heat dissipation of the heat dissipation medium after heat exchange with the soil, a third delivery pump 33 for delivering the heat dissipation medium after heat exchange, and a third delivery pipe 34 corresponding to the third delivery pump 33; wherein, one end of the second transfer pipe 31 is connected to the first delivery mechanism 2, and the other end is respectively connected to one end of the plurality of heat dissipation pipes 32; the other ends of the plurality of heat dissipation pipes 32 are respectively connected to one end of the third delivery pipe 34; the other end of the third delivery pipe 34 is connected to the reflux mechanism 4; the third delivery pump 33 is arranged on one side of the third delivery pipe 34 close to the heat dissipation pipe 32; the reflux mechanism 4 is connected to the second transfer pipe 31. The heat dissipation medium exchanges heat with the soil in the heat dissipation pipe buried underground, and utilizes the natural low temperature characteristics of the underground soil to achieve an efficient and natural cooling effect. The provision of the third delivery pump ensures the circulation of the heat dissipation medium between the heat dissipation pipe and the reflux mechanism, enhances the fluidity of the heat dissipation medium, and further improves the heat dissipation efficiency. The filling of phase change materials and the use of heat dissipation fins optimize the heat exchange performance of the heat pipe, so that the heat dissipation medium can maintain a high heat exchange efficiency under different temperature conditions, while accelerating the transfer process of heat energy and improving the heat dissipation rate.

[0033] Specifically, Figure 3 As shown, the heat dissipation medium delivered by the first delivery mechanism 2 and the reflux mechanism 4 is received by the second transfer tube 31, and the heat dissipation medium is divided into multiple channels by the second transfer tube 31 and enters multiple heat dissipation pipes 32 in sequence. The heat dissipation pipes 32 are made of high thermal conductivity materials. The heat dissipation medium performs efficient heat exchange with the soil in the heat dissipation pipes 32, so that the heat energy absorbed by the heat dissipation medium is dissipated into the soil, which has the effect of heat dissipation and cooling, and provides support for heat dissipation under different temperature conditions; when the heat dissipation medium enters the third delivery pipe 34, it is delivered to the reflux mechanism 4 by the third delivery pump 33.

[0034] like Figures 1 to 3As shown, the reflux mechanism 4 includes: a third transfer tube 41 for receiving the heat dissipation medium, a detection tube 42, a temperature sensor 43 for detecting the temperature of the heat dissipation medium in the detection tube 42, a fourth delivery pump 44 for delivering the heat dissipation medium that does not meet the requirements in the detection tube 42, a reflux tube 45 corresponding to the fourth delivery pump 44, a fifth delivery pump 46 for delivering the heat dissipation medium that meets the requirements in the detection tube 42, a fourth delivery tube 47 corresponding to the fifth delivery pump 46, a first solenoid valve 48, a second solenoid valve 49 and a third solenoid valve 410; one end of the third transfer tube 41 is connected to the third delivery tube 34, and the other end is connected to one end of the detection tube 42; the detection tube 42 The other end is connected with one end of the return pipe 45 and one end of the fourth delivery pipe 47 respectively; the other end of the return pipe 45 is connected with the second transfer pipe 31; the fourth delivery pipe 47 is connected with the second delivery mechanism 5; the first solenoid valve 48 is arranged at the connection between the detection pipe 42 and the return pipe 45; the second solenoid valve 49 is arranged at the connection between the detection pipe 42 and the fourth delivery pipe 47; the third solenoid valve 410 is arranged at the connection between the return pipe 45 and the second transfer pipe 31; the temperature sensor 43 is arranged in the detection pipe 42; the fourth delivery pump 44 is arranged on the side of the return pipe 45 close to the detection pipe 42; the fifth delivery pump 46 is arranged on the side of the fourth delivery pipe 47 close to the detection pipe 42. The real-time monitoring function of the temperature sensor can accurately determine whether the heat dissipation medium reaches the preset cooling temperature, so as to determine whether it needs to flow back to the soil heat pipe mechanism for secondary heat dissipation. The setting of the first solenoid valve, the second solenoid valve and the third solenoid valve realizes the intelligent control of the flow path of the heat dissipation medium, ensures that the system can automatically adjust the heat dissipation process according to the temperature state of the heat dissipation medium, and improves the automatic adaptability and intelligence level of the system. The design of the reflux mechanism avoids the heat dissipation medium from directly returning to the heat exchange mechanism due to excessive temperature, reduces the risk of the automatic switch overheating again, and improves the safety and stability of the system.

[0035] Specifically, Figure 3 As shown, the third transfer tube 41 receives the heat dissipation medium transported by the third delivery pipe 34 and guides it into the detection tube 42. The detection tube 42 is provided with a temperature sensor 43 for detecting the temperature of the heat dissipation medium in the detection tube 42. If the detected temperature of the heat dissipation medium meets the requirements, the first solenoid valve 48 is closed and the second solenoid valve 49 is opened, so that the heat dissipation medium passes through the fifth delivery pump 46 and is then transported back to the heat exchange mechanism 1 through the fourth delivery pipe 47; if the detected temperature of the heat dissipation medium does not meet the requirements, the second solenoid valve 49 is closed, and the first solenoid valve 48 and the second solenoid valve 49 are opened, and the heat dissipation medium passes through the fourth delivery pump 44 and the return pipe 45 to re-enter the soil heat pipe mechanism 3 for secondary cooling until it meets the requirements; to avoid backflow of the heat dissipation medium, the third solenoid valve 410 is in a normally closed state; through real-time temperature monitoring and automatic switching, the heat dissipation medium is effectively processed to ensure that the equipment obtains a suitable cooling effect.

[0036] like Figure 3 As shown, multiple heat pipes 32 are filled with phase change materials 35 to optimize heat exchange efficiency under different temperature conditions. The use of phase change materials can optimize heat exchange efficiency under different temperature conditions. Especially in an environment with large temperature fluctuations, the phase change materials can absorb or release a large amount of heat to keep the temperature of the heat dissipation medium relatively stable, thereby improving the thermal stability of the heat dissipation system. The presence of phase change materials allows the heat pipes to absorb more heat energy during peak loads and release it slowly during off-peak periods, effectively avoiding potential damage to the automation switch equipment caused by sudden temperature rises and falls.

[0037] The heat pipe 32 is filled with a phase change material 35, and the distribution method can be designed in various forms (such as particles, plates, films, etc.), which makes the heat pipe 32 more flexible in different soil conditions and spatial layouts, and compatible with existing facilities, and the design is more adaptable; the phase change material 35 can absorb or release a large amount of heat when the temperature changes. This feature enables the heat dissipation device to maintain a stable temperature under temperature fluctuations, thereby improving the heat dissipation efficiency; when the automatic switch 6 device is working under high load, the heat dissipation medium absorbs a large amount of heat energy and enters the heat pipe 32. It is no longer limited to the heat conduction through the heat pipe 32 itself to cool the heat dissipation medium. Instead, part of the heat energy of the heat dissipation medium is dissipated through the heat pipe 32, and the other part of the heat energy is absorbed by the phase change material 35, so that the heat dissipation medium can be quickly cooled, and the phase change material 35 dissipates the heat energy. In this heat dissipation method, heat can be effectively absorbed during peak loads, and can be slowly released during off-peak periods, thereby avoiding potential damage to the automatic switch 6 device due to a sudden increase in temperature.

[0038] Specifically, the phase change material 35 can be selected from paraffin, saline solution, etc., which can undergo rapid phase change within an appropriate temperature range. When used, different types of phase change materials 35 can be applied to different sections of the heat pipe 32 according to actual usage requirements to achieve more precise heat management.

[0039] like Figures 1 to 3 As shown, the outer sides of the plurality of heat dissipation pipes 32 are provided with heat dissipation fins for accelerating heat exchange. The provision of the heat dissipation fins significantly increases the surface area of ​​the heat dissipation pipe in contact with the soil, accelerating the heat exchange rate inside and outside the heat dissipation pipe. This design can improve the heat dissipation efficiency, especially when the automatic switch is working under high load, the improvement of the heat dissipation capacity helps to maintain the stable operation of the equipment and avoid abnormal operation due to overheating.

[0040] Specifically, the heat dissipation fins are arranged on the heat dissipation pipe 32 to accelerate the heat exchange rate between the heat dissipation medium in the heat dissipation pipe 32 and the soil, so that when the equipment is working at a high load, the heat dissipation capacity is improved to avoid unstable operation due to overheating. The heat dissipation medium can be water, coolant, nitrogen or air.

[0041] like Figures 1 to 3 As shown, the automatic switch heat dissipation device based on soil source heat pump technology also includes: a backwashing system, which is connected between the connection between the second transfer pipe 31 and the first conveying mechanism 2 and the connection between the third conveying pipe 34 and the return mechanism 4. The design of the backwashing system connected between the second transfer pipe and the first conveying mechanism and the third conveying pipe and the return mechanism can clean the pipes in the system regularly or on demand to prevent the heat dissipation efficiency from decreasing due to the deposition of heat dissipation medium or clogging of impurities. Through the operation of the backwashing system, the smoothness of the entire heat dissipation system is maintained, the service life of the system is extended, and the maintenance cost is reduced.

[0042] The backwashing system includes a backwashing pump for providing high-pressure water or air required for backwashing; a backwashing pipeline connecting the backwashing pump with the inlet and outlet of the heat dissipation pipe 32; a filter installed in the backwashing pipeline for filtering the cleaning medium before backwashing to avoid the introduction of additional impurities; and a solenoid valve for controlling the switching between the backwashing pipeline and the main circulation pipeline of the system to ensure that the normal operation of other components is not affected during backwashing.

[0043] When the backwash system is operating normally:

[0044] The heat dissipation medium passes through the first conveying mechanism 2 from the heat exchange mechanism 1 and enters the heat dissipation pipe 32 of the soil heat pipe mechanism 3 through the second transfer pipe 31. After flowing out of the heat dissipation pipe 32, it reaches the return mechanism 4 through the third conveying pipe 34, and is sent back to the heat exchange mechanism 1 by the second conveying mechanism 5 after passing the inspection, forming a cycle.

[0045] Backwash system backwash operation:

[0046] Close the normal delivery valve between the first delivery mechanism 2 and the soil heat pipe mechanism 3, such as the valve at the second transfer pipe 31. Turn on the backwash pump and deliver the cleaning medium (such as high-pressure water or air) to the outlet end of the heat dissipation pipe 32 through the backwash pipeline. The cleaning medium flows through the heat dissipation pipe 32 in reverse under high pressure to flush out the impurities in the pipe. The cleaned medium is discharged through the backwash pipeline, or circulated to the backwash pump again through the filter until the cleaning is completed. After the cleaning is completed, turn off the backwash pump and the corresponding valves to restore the normal operation of the system.

[0047] like Figures 1 to 3As shown, the second delivery mechanism 5 includes: a sixth delivery pump 51 and a fifth delivery pipe 52 corresponding to the sixth delivery pump 51; the sixth delivery pump 51 is arranged on the fifth delivery pipe; one end of the fifth delivery pipe 52 is connected to the reflux mechanism 4, and the other end is connected to the heat exchange mechanism 1. The arrangement of the sixth delivery pump and the fifth delivery pipe ensures that the heat dissipation medium that has been tested and meets the requirements can be stably returned to the heat exchange mechanism, forming a closed circulation system.

[0048] This design ensures the continuous circulation of the heat dissipation medium, improves the heat dissipation efficiency and automation level of the system, and also helps to maintain the purity of the heat dissipation medium and prevent pollution to the system.

[0049] like Figures 1 to 3 As shown, the automatic switch heat dissipation device based on soil source heat pump technology also includes: a control mechanism, which is electrically connected to the heat exchange mechanism 1, the first conveying mechanism 2, the soil heat pipe mechanism 3, the reflux mechanism 4 and the second conveying mechanism 5 respectively. The electrical connection between the control mechanism and the heat exchange mechanism, the first conveying mechanism, the soil heat pipe mechanism, the reflux mechanism and the second conveying mechanism realizes the comprehensive monitoring and intelligent control of the heat dissipation system. The use of the microcontroller can adjust the working state of the system in real time according to the sensor data, such as controlling the speed of the pump and adjusting the switch of the solenoid valve to ensure that the temperature and flow of the heat dissipation medium meet the heat dissipation requirements of the automatic switch. The intelligent algorithm and safety protection mechanism in the control mechanism improve the automation level and operation safety of the system. At the same time, through communication with the external monitoring system or cloud platform, remote monitoring and management of the heat dissipation device are realized, which enhances the scalability and intelligence of the system.

[0050] The control mechanism includes: a microcontroller (MCU, PLC, etc.), multiple sensors and electronic valves. By setting multiple sensors (such as NTC thermistors or thermocouples) at key positions (such as the inlet, outlet and reflux mechanism 4 of the heat exchange mechanism 1), the temperature of the heat dissipation medium is monitored in real time; these sensors are connected to the microcontroller, and the microcontroller will analyze and make decisions based on the temperature data read by the sensors. The control mechanism adjusts the opening and closing of different delivery paths through the first solenoid valve 48, the second solenoid valve 49, the third solenoid valve 410 and the electronic valve to control the flow direction of the heat dissipation medium. For example, when it is detected that the temperature of the heat dissipation medium rises, the microcontroller will trigger the solenoid valve to open the cooling path to allow the low-temperature medium to flow into the system; the control mechanism will dynamically adjust the working states of the first delivery pump 12, the second delivery pump 22, the third delivery pump 33, the fourth delivery pump 44 and the fifth delivery pump 46 according to the actual temperature and flow requirements. For example, when the heat dissipation requirement is high, the microcontroller can increase the pump speed to increase the medium flow and achieve higher heat dissipation efficiency.

[0051] Optionally, the control mechanism can be equipped with a human-machine interface, such as a liquid crystal display and a touch screen, allowing the operator to view the system temperature, flow status and operating parameters in real time, while providing manual control and historical data recording functions. The interface design is simple and easy to understand, which helps users quickly get started and make necessary adjustments and monitoring.

[0052] Optionally, the control mechanism has an embedded intelligent algorithm that can predict and analyze temperature change trends, determine the system heat dissipation requirements in advance, and optimize and adjust according to ambient temperature, equipment load changes, and heat dissipation efficiency to ensure that the equipment runs at the optimal temperature. Various working modes can be set, such as normal mode, energy protection mode, and high-efficiency mode, to meet the needs of different application scenarios.

[0053] Optionally, multiple safety protection mechanisms can be integrated into the control mechanism, such as over-temperature alarm, insufficient flow alarm, etc.; once an abnormal situation occurs, the system will automatically stop and prompt the operator through the alarm device; an automatic restart function can be integrated to enable the equipment to quickly resume operation after the fault is restored.

[0054] Optionally, the control mechanism can also communicate with an external monitoring system or cloud platform to provide remote monitoring and management functions; send real-time data to the cloud through wireless or wired connections to promote data management and intelligent decision-making of smart devices.

[0055] The present invention is an automatic switch heat dissipation device based on soil source heat pump technology. By adopting soil source heat pump technology, phase change material 35 and a multi-stage heat exchange structure, it can significantly improve the heat exchange efficiency of the heat dissipation system, ensure that the temperature of the automatic switch 6 and other electronic equipment is maintained within a safe range, thereby reducing failures and damages caused by overheating; by making full use of the natural cold source of underground soil, it reduces dependence on traditional cooling systems (such as compressors and refrigerants), thereby reducing energy consumption and environmental impact, especially in the context of the increasing attention paid to the use of renewable energy, showing good environmental adaptability.

[0056] In summary, the present invention has the following beneficial effects:

[0057] 1. By adopting soil source heat pump technology, phase change materials and multi-stage heat exchange structure, the heat exchange efficiency of the heat dissipation system can be significantly improved, ensuring that the temperature of automatic switches and other electronic equipment remains within a safe range, thereby reducing failures and damage caused by overheating; by making full use of the natural cold source of underground soil, the dependence on traditional cooling systems (such as compressors and refrigerants) is reduced, thereby reducing energy consumption and environmental impact, especially in the context of the increasing attention paid to the use of renewable energy, showing good environmental adaptability.

[0058] 2. Equipped with an automatic control mechanism, it can monitor the temperature of the heat dissipation medium in real time and automatically adjust the flow and working status according to actual needs. This intelligent design makes the operation of the heat dissipation system simpler, more intuitive, more adaptable, and can automatically optimize operation under different load and environmental conditions.

[0059] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0060] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0061] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
