[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a building electrical overvoltage protection device to solve the technical problem of insufficient heat dissipation in the prior art.

[0022] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: like Figures 1-3 As shown. This application provides a building electrical overvoltage protection device, including a mounting plate 1, an overvoltage protector body 2, and a heat sink 3.

[0023] The overvoltage protector body 2 is mounted on the mounting plate 1.

[0024] The heat sink 3 is installed on the side of the overvoltage protector body 2.

[0025] The heat dissipation box 3 has an installation opening on its side wall. Inside the heat dissipation box 3 are a miniature water pump 4, a water storage box 5, a cooler, water supply pipes, and a heat dissipation assembly 6. The heat dissipation assembly 6 penetrates the installation opening and is attached to the surface of the overvoltage protector body 2. The water storage box 5 is circulated with the heat dissipation assembly 6 via the miniature water pump 4 and the water supply pipes. The cold end of the cooler is attached to the outer wall of the water storage box 5. When the overvoltage protector body 2 operates, it generates heat. This heat is absorbed by the heat dissipation assembly 6, which is in close contact with its surface. Driven by the miniature water pump 4, the cooling water inside the heat dissipation assembly 6 circulates between the water storage box 5 and the heat dissipation assembly 6 through the water supply pipes, carrying away and storing the heat in the water storage box 5, thus achieving continuous and efficient heat dissipation.

[0026] This application utilizes a water-cooling system comprised of a water storage box 5 and a heat dissipation component 6 to effectively improve the heat dissipation efficiency of the overvoltage protector body 2. Compared to traditional air cooling, water cooling can more efficiently remove the heat generated during the operation of the overvoltage protector body 2. The close fit design between the heat dissipation component 6 and the surface of the overvoltage protector body 2 ensures efficient heat transfer. The circulating water cooling system continuously removes heat from the overvoltage protector body 2, preventing heat accumulation and extending the device's lifespan.

[0027] In some embodiments of this application, the heat dissipation component 6 includes a heat-conducting plate 61 and a circulating condensing coil 62. The heat-conducting plate 61 is attached to the surface of the overvoltage protector body 2. The circulating condensing coil 62 is embedded inside the heat-conducting plate 61 and its inlet and outlet are respectively connected to the heat dissipation component 6 through the micro water pump 4 and the water supply pipe.

[0028] The heat-conducting plate 61 is tightly attached to the surface of the overvoltage protector body 2, efficiently absorbing the heat generated during its operation and quickly conducting the heat to the circulating condensing coil 62 embedded inside it; when the cooling water flows through the coil, it absorbs heat through heat exchange with the heat-conducting plate 61, and then is driven by the micro water pump 4 to flow back to the water storage box 5 through the water supply pipe, forming a closed-loop heat dissipation cycle.

[0029] The combination of the heat-conducting plate 61 and the coil enables rapid heat conduction and diffusion, significantly improving heat dissipation efficiency. The embedded coil design is not only compact but also maximizes the use of the heat-conducting plate 61 area, ensuring that heat is fully absorbed. In addition, this structure enhances the stability and reliability of the heat dissipation system, effectively preventing equipment failures caused by local overheating and further extending the service life of the device.

[0030] In some embodiments of this application, a partition 7 is also included, which is fixed inside the heat dissipation box 3 and divides the heat dissipation box 3 into a heat conduction cavity 3a and a heat exchange cavity 3b. The heat dissipation assembly 6 is located in the heat conduction cavity 3a, and the micro water pump 4 and the water storage box 5 are located in the heat exchange cavity 3b.

[0031] The heat dissipation component 6 is located in the heat conduction cavity 3a and directly contacts the overvoltage protector body 2 to absorb heat; while the micro water pump 4 and the water storage box 5 are located in an independent heat exchange cavity 3b. The two form a circulating water path through the water supply pipe. After the cooling water absorbs heat by flowing through the heat dissipation component 6, it returns to the water storage box 5 in the heat exchange cavity 3b to release heat.

[0032] Spatial isolation effectively avoids thermal interference between high-temperature components, improving heat dissipation efficiency. At the same time, functional zoning makes the structure more compact and orderly, facilitating maintenance and repair. In addition, the isolation design can reduce the impact of vibration and heat generated by the water pump 4 on heat dissipation performance, ensuring the stability and reliability of system operation and further extending the service life of the device.

[0033] In some embodiments of this application, a cooling fan is also included, wherein the cooler is a semiconductor cooler, and the cooling fan is directed toward the hot end of the cooler.

[0034] The cooler can be a semiconductor cooler. After the cooler is powered on, its cold end absorbs the heat of the circulating water in the water storage box 5, which lowers the water temperature. Then, the low-temperature cooling water, which is pressurized by the micro water pump 4, flows through the heat dissipation component 6 and can more efficiently absorb the heat generated by the overvoltage protector body 2. It then returns to the water storage box 5 for secondary cooling, forming an enhanced heat dissipation cycle.

[0035] The combination of active cooling and passive water cooling breaks through the limitations of traditional water cooling systems that rely solely on ambient temperature for heat dissipation. Even in extreme high-temperature environments, it can maintain a low cooling water temperature, significantly improving the heat dissipation margin and thermal stability of the overvoltage protector. This effectively avoids performance degradation or failure caused by overheating, further extending the service life and reliability of the device under harsh conditions.

[0036] In some embodiments of this application, the heat-conducting plate 61 has an inner cavity, and the circulating condensing coil 62 is embedded in the inner cavity in a reciprocating manner and contacts at least two inner wall surfaces of the heat-conducting plate 61 for heat conduction. The circulating condensing coil 62 is arranged in a multi-pass reciprocating pattern.

[0037] The heat-conducting plate 61 is made of copper plate, and the coils are arranged in an S-shape or spiral shape. When the cooling water flows through the multi-pass reciprocating coils, the residence time and path of the water flow in the heat-conducting plate 61 are extended, increasing the contact area and heat exchange time with the heat-conducting plate 61, thereby more efficiently absorbing the heat conducted by the overvoltage protector body 2 through the heat-conducting plate 61.

[0038] The multi-pass reciprocating arrangement significantly increases the contact area between the coil and the heat conduction plate 61, enhancing the heat transfer efficiency; the extended water flow path allows the cooling water to fully absorb heat, improving the heat exchange efficiency; at the same time, the compact spiral structure maximizes heat exchange within a limited space, making the heat dissipation component 6 structure more compact and efficient, further improving the performance and reliability of the entire heat dissipation system.

[0039] In some embodiments of this application, the heat dissipation assembly 6 further includes a temperature sensor and a controller. The temperature sensor is attached to the inner wall of the heat-conducting plate 61, and the controller is electrically connected to the temperature sensor, the micro water pump 4, and the cooler, respectively.

[0040] The temperature sensor monitors the temperature of the inner wall of the heat-conducting plate 61 in real time and transmits the data to the controller. The controller automatically adjusts the working status of the micro water pump 4 and the cooler according to the preset temperature threshold. When the temperature rises, the controller increases the speed of the water pump 4 or starts the cooler to enhance heat dissipation. When the temperature drops, the controller reduces power consumption.

[0041] The system enables on-demand adjustment of the heat dissipation system, avoiding energy waste; intelligent control ensures that the overvoltage protector body 2 always operates within the optimal temperature range, effectively preventing overheating or excessive cooling; at the same time, the system responds quickly and can dynamically adjust the heat dissipation strategy according to load changes, significantly improving the operational stability and reliability of the device, further extending the service life of the equipment and reducing maintenance costs.

[0042] In some embodiments of this application, the heat dissipation assembly 6 further includes a filter screen, and the side wall of the heat dissipation box 3 is provided with ventilation holes, with the filter screen covering the surface of the ventilation holes.

[0043] When there is a temperature difference between the inside and outside of the heat sink 3, air will naturally circulate through the ventilation holes to help dissipate heat, while the filter screen can effectively block dust, impurities and other particles in the outside air from entering the heat sink 3.

[0044] The filter effectively prevents dust and foreign objects from entering the heat dissipation system, avoiding problems such as clogging water pipes, adhering to the surface of heat dissipation components 6 and affecting heat dissipation efficiency, and corroding electronic components. It significantly improves the long-term operational reliability and maintenance cycle of the system. At the same time, the structure is simple and practical, and without increasing additional energy consumption, it effectively protects the entire heat dissipation system, ensuring the stable working performance of the water cooling device in various complex environments.

[0045] In some embodiments of this application, the water storage box 5 has a threaded sealed water inlet at the top and a drain valve at the bottom.

[0046] When the system needs to be replenished with water or the coolant replaced, liquid can be injected by unscrewing the top inlet, and the threaded structure ensures a tight seal. When the system needs maintenance or cleaning, the internal liquid can be completely drained through the drain valve at the bottom.

[0047] The threaded seal water inlet facilitates daily refrigerant filling and effectively prevents coolant evaporation and leakage, ensuring the system's airtightness and stability. Meanwhile, the bottom drain valve completely solves the problem of incomplete drainage in traditional devices, facilitating thorough cleaning and maintenance, effectively preventing the long-term accumulation of scale and impurities, thereby extending the service life of the entire heat dissipation system, simplifying the maintenance process, and reducing maintenance costs.

[0048] In some embodiments of this application, a plurality of connecting plates 8 are also included. The plurality of connecting plates 8 are bolted to the two side walls of the overvoltage protector body 2 respectively. Two connecting plates 8 on the same side are symmetrically distributed and bolted to the two ends opposite to the heat sink 3 respectively.

[0049] In this embodiment, multiple connecting plates 8 are provided, which are bolted to the two side walls of the overvoltage protector body 2 and to both ends of the heat sink 3 through mounting holes 9, forming a stable assembly structure. The connecting plates 8 serve as intermediate transition parts, tightly fixing the overvoltage protector body 2 and the heat sink 3 together, ensuring a stable contact pressure between the heat dissipation component 6 and the overvoltage protector body 2, thereby ensuring heat conduction efficiency.

[0050] The modular connection structure facilitates installation, disassembly, and maintenance. At the same time, the symmetrically distributed connection design makes the stress distribution more uniform, avoiding structural deformation or damage caused by stress concentration. The bolt connection method not only provides reliable mechanical strength, but also allows the installation position and pressure to be adjusted according to actual needs, ensuring optimal contact between the heat dissipation component 6 and the overvoltage protector body 2, thereby improving the stability and long-term reliability of the heat dissipation system.

[0051] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: This application utilizes a water-cooling system comprised of a water storage box 5 and a heat dissipation component 6 to effectively improve the heat dissipation efficiency of the overvoltage protector body 2. Compared to traditional air cooling, water cooling can more efficiently remove the heat generated during the operation of the overvoltage protector body 2. The close fit design between the heat dissipation component 6 and the surface of the overvoltage protector body 2 ensures efficient heat transfer. The circulating water cooling system continuously removes heat from the overvoltage protector body 2, preventing heat accumulation and extending the device's lifespan.

[0052] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0053] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
