Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more particularly to a transformer cooling device for electronic equipment. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers can be classified according to their application: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, angle transformers, high-current transformers, and excitation transformers. Transformers are fundamental equipment for power transmission and distribution, widely used in industry, agriculture, transportation, and urban communities. There are approximately 17 million transformers in operation in my country, with a total capacity of approximately 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, indicating significant potential for energy conservation.

[0003] After installation, existing transformers generate a significant amount of heat during operation. Since the transformer operates in a sealed environment, cooling devices are needed to prevent damage from this heat. Existing cooling devices typically rely on airflow to accelerate gas flow within the transformer enclosure, thereby increasing gas exchange between the inside and outside of the enclosure. However, gas is a poor conductor of heat, and this rapid gas flow is inefficient at removing heat from the transformer's outer walls. This results in limited effectiveness of existing cooling devices, making the transformer prone to damage during long-term use. Summary of the Invention

A cooling seat is fixedly connected to the top outer wall of the mounting base, and a cooling assembly is provided on the cooling seat.

[0007] As a further embodiment of the present invention, the inner walls of the mounting slots near the limiting plate are provided with sliding grooves, and the inner wall of each sliding groove is slidably connected with a sliding block, which is fixedly connected to the outer wall of the limiting plate.

[0008] As a further embodiment of the present invention, both ends of the top outer wall of the embedding seat are fixedly connected to fixing plates, and the outer walls of the opposite sides of the two fixing plates are fixedly connected to hydraulic cylinders at equal distances. The clamping plate is fixedly connected to the output end of multiple hydraulic cylinders on the same side.

[0009] As a further embodiment of the present invention, heat transfer components are provided on both outer walls of the cooling seat, and a spraying component is provided on the top of the cooling seat.

[0010] As a further embodiment of the present invention, the heat transfer component includes a thermoelectric cooler, and mounting holes are equally spaced on both outer walls of the cooling base. The thermoelectric cooler is fixedly connected to the inner wall of each mounting hole. The heat-absorbing end of the thermoelectric cooler is located inside the cooling base, and the heat-dissipating end of the thermoelectric cooler is located outside the cooling base.

[0011] As a further embodiment of the present invention, the cooling seat is fixedly connected to the outer wall of the semiconductor cooling chip, and the top inner wall and bottom inner wall of the heat dissipation frame are fixedly connected to the blower plate. The outer walls of the two blower plates on opposite sides are provided with connecting holes, and the inner walls of each pair of corresponding connecting holes are fixedly connected to the same connecting plate. The outer walls of the two blower plates facing the heat dissipation end of the semiconductor cooling chip are provided with blower holes at equal intervals.

[0012] As a further embodiment of the present invention, the outer walls of both sides of the heat dissipation frame are fixedly connected to a frame, and the top outer walls of both frames are fixedly connected to a blower, the blower end of which is connected to the interior of the connecting plate through a pipe.

[0013] As a further embodiment of the present invention, the spraying assembly includes multiple nozzles, and the top outer wall of the cooling seat has an embedding groove, the inner wall of the embedding groove is slidably connected to an ejector frame, the top outer wall of the ejector frame has an insertion hole, the inner wall of the insertion hole is connected to a connecting pipe, the connecting pipe has spray holes at equal intervals facing the outer wall of the transformer body, and the nozzles are fixedly connected to the inner wall of the spray holes.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. By incorporating a cooling assembly, the transformer body is installed in an embedded base during cooling. As the transformer operates, the ambient temperature rises. Temperature sensors monitor the temperature; if it is too high, a cylinder is adjusted to press a pressure plate against the embedded base, causing it to press down. This forces the cooling water inside the cooling base to the sides, raising the water level. As the transformer body descends, the contact area between the condenser tubes on both sides of the cooling base and the transformer body increases. Cooling water is then forced into the condenser tubes by the pressure of the embedded base. The heat-conducting rods on the outside of the condenser tubes transfer heat from the transformer surface to the condenser tubes, where the cooling water absorbs it, achieving contact cooling. Furthermore, the cooling effect can be adjusted based on the ambient temperature, ensuring the transformer body remains in a safe environment and enhancing the overall value of the transformer cooling device.

[0016] 2. When installing the transformer body using the clamping assembly, it is placed in the mounting slot of the embedding seat. The transformer body and the limiting plate are squeezed together, which causes the sliding block on the limiting plate to slide on the inner wall of the sliding groove. The compression spring is compressed, and the reaction force of the compression spring causes the limiting plate to clamp the transformer body for the first time. Then, the No. 1 hydraulic cylinder is adjusted to drive the clamping plate to clamp the outer wall of the transformer body above the mounting slot, thus clamping it for the second time and ensuring the stability of the transformer body after installation.

[0017] 3. By incorporating heat transfer components, when the transformer body is cooled by the cooling components, the heat absorption end of the thermoelectric cooler absorbs heat from the cooling water inside the cooling base and discharges it through the heat dissipation end. During the heat dissipation process of the thermoelectric cooler, the blower is activated, and the blower blows a large amount of gas into the blower plate. This gas is blown out from the blower hole, thereby carrying the heat discharged from the heat dissipation end. This heat is quickly carried away from the transformer body by the gas, thus avoiding secondary damage to the transformer body.

[0018] 4. By incorporating a spraying assembly, when the temperature sensor detects a sharp increase in the temperature of the transformer body, it indicates that the transformer body may be experiencing spontaneous combustion due to aging of the wiring caused by long-term operation. In this case, the cylinder drives the pressure plate to press down on the embedded seat, causing the embedded seat to descend to its lowest point. The cooling water is then squeezed to the top of the cooling seat, and the cooling water squeezes the ejector frame, causing the ejector frame to move to its highest point. The cooling water then enters the connecting pipe through the ejector frame and is subsequently sprayed out through the nozzles. The direction of the cooling water spray is towards the transformer body, thus extinguishing the fire on the transformer body and providing safety protection, thereby improving the functionality of the transformer cooling device.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-6The electronic device transformer cooling device includes a mounting base 1 and a transformer body 5. A cooling seat 3 is fixedly connected to the top outer wall of the mounting base 1, and a cooling assembly is provided on the cooling seat 3. The cooling assembly includes an embedded seat 14 and a condenser tube 13. A lifting hole is opened on the bottom inner wall of the cooling seat 3, and the embedded seat 14 is slidably connected to the inner wall of the lifting hole. Connection holes are opened at equal intervals on both sides of the inner wall of the cooling seat 3, and the condenser tube 13 is fixedly connected to the inner wall of each connection hole. The condenser tube 13 is connected to the cooling seat 3. A heat-conducting rod 17 is distributed in a ring on the outer wall of each condenser tube 13. The heat-conducting rod 17 is in contact with the outer wall of the transformer body 5. A wire plate 4 is fixedly connected to the inner wall of the cooling seat 3 on the side close to the transformer body 5, and a temperature sensor 2 is provided on the wire plate 4. Fixing brackets 10 are fixedly connected to both sides of the outer wall of the cooling seat 3, and cylinders 11 are fixedly connected to the outer walls of the two fixing brackets 10. A pressure plate 9 is fixedly connected to the output end of the two cylinders 11, and the pressure plate 9 is located above the embedded seat 14.

[0028] By incorporating a cooling assembly, when cooling the transformer body 5, the transformer body 5 is installed in the embedded base 14. As the transformer body 5 operates, the temperature of its surrounding environment rises. The temperature is monitored by the temperature sensor 2. If the temperature is too high, the regulating cylinder 11 drives the pressure plate 9 to squeeze the embedded base 14, causing the embedded base 14 to press down. The embedded base 14 then squeezes the cooling water inside the cooling seat 3 to both sides, causing the cooling water level on both sides to rise. As the embedded base 14 presses down, the transformer body 5 descends, increasing the contact area between the condenser tubes 13 on both sides of the cooling seat 3 and the transformer body 5. Cooling water is poured into the condenser tubes 13 under the pressure of the embedded base 14. The heat-conducting rods 17 on the outside of the condenser tubes 13 transfer the heat from the transformer surface to the condenser tubes 13, where the cooling water absorbs it, thus achieving contact cooling. At the same time, by monitoring the temperature sensor 2, the cooling effect can be adjusted according to the temperature of the transformer's environment, ensuring that the transformer body 5 is always in a safe environment and improving the usability of the transformer cooling device.

[0029] Reference Figure 1 and Figure 4 The embedding seat 14 is provided with a clamping assembly, which includes a clamping plate 18 and a limiting plate 25.

[0030] In this invention, the top outer wall of the embedding seat 14 has a mounting groove 19, and the transformer body 5 is placed inside the mounting groove 19. Compression springs 24 are fixedly connected at equal distances on both sides of the inner wall of the mounting groove 19, and the limiting plate 25 is fixedly connected to the other end of the plurality of compression springs 24 located on one side.

[0031] In this invention, sliding grooves 20 are provided on both inner walls of the mounting groove 19 near the limiting plate 25, and a sliding block 21 is slidably connected to the inner wall of each sliding groove 20, and the sliding block 21 is fixedly connected to the outer wall of the limiting plate 25.

[0032] In this invention, both ends of the top outer wall of the embedding seat 14 are fixedly connected to fixing plates 23, and the outer walls of the opposite sides of the two fixing plates 23 are fixedly connected to hydraulic cylinders 22 at equal distances. The clamping plate 18 is fixedly connected to the output end of multiple hydraulic cylinders 22 on the same side. By setting the clamping assembly, when installing the transformer body 5, it is placed in the placement groove 19 of the embedding seat 14, and the transformer body 5 is squeezed with the limiting plate 25, thereby driving the sliding block 21 on the limiting plate 25 to slide on the inner wall of the sliding groove 20. The compression spring 24 is compressed, and the reaction force of the compression spring 24 drives the limiting plate 25 to clamp the transformer body 5 once. Then, the hydraulic cylinders 22 are adjusted to drive the clamping plate 18 to clamp the outer wall of the transformer body 5 above the placement groove 19, thus clamping it twice to ensure the stability of the transformer body 5 after installation.

[0033] Reference Figure 1 , Figure 5 and Figure 6 The cooling base 3 has heat transfer components on both outer walls and a spray component on the top.

[0034] Reference Figure 5 The heat transfer component includes a thermoelectric cooler 29, and mounting holes 15 are equally spaced on both sides of the outer wall of the cooling base 3. The thermoelectric cooler 29 is fixedly connected to the inner wall of each mounting hole 15. The heat-absorbing end of the thermoelectric cooler 29 is located inside the cooling base 3, and the heat-dissipating end of the thermoelectric cooler 29 is located outside the cooling base 3.

[0035] In this invention, a heat dissipation frame 8 is fixedly connected to the outer wall of the cooling base 3 located outside the semiconductor cooling chip 29, and a blower plate 7 is fixedly connected to the top inner wall and the bottom inner wall of the heat dissipation frame 8. A connecting hole is opened on the outer wall of the opposite side of the two blower plates 7, and the same connecting plate 26 is fixedly connected to the inner wall of each pair of corresponding connecting holes. Blower holes 28 are opened at equal intervals on the outer wall of the two blower plates 7 facing the heat dissipation end of the semiconductor cooling chip 29.

[0036] In this invention, both outer walls of the heat dissipation frame 8 are fixedly connected to the frame 27, and the top outer walls of the two frames 27 are fixedly connected to the blower 6. The blower end of the blower 6 is connected to the inside of the connecting plate 26 through a pipe.

[0037] Reference Figure 6The spraying assembly includes multiple nozzles 30, and the top outer wall of the cooling base 3 has an embedding groove 16. An ejector frame 12 is slidably connected to the inner wall of the embedding groove 16. An insertion hole is opened on the top outer wall of the ejector frame 12, and a connecting pipe 31 is inserted into the inner wall of the insertion hole. The connecting pipe 31 has spray holes evenly spaced facing the outer wall of the transformer body 5. The nozzles 30 are fixedly connected to the inner wall of the spray holes. By providing the spraying assembly, when the temperature sensor 2 detects a sharp increase in temperature at the transformer body 5, it indicates that the internal wiring of the transformer body 5 may be aging due to long-term operation. In the event of a fire, cylinder 11 drives pressure plate 9 to press down on the embedded seat 14, causing the embedded seat 14 to descend to its lowest point. The cooling water is then squeezed to the top of the cooling seat 3, and the cooling water squeezes the ejector frame 12, causing the ejector frame 12 to move to its highest point. The cooling water then enters the connecting pipe 31 through the ejector frame 12 and is subsequently sprayed out through the nozzle 30. The direction of the cooling water spray is towards the transformer body 5, which extinguishes the fire on the transformer body 5, thereby providing safety protection and improving the functionality of the transformer cooling device.

[0038] In use, the transformer body 5 is placed in the mounting slot 19 of the embedding seat 14. The transformer body 5 is pressed against the limiting plate 25, causing the sliding block 21 on the limiting plate 25 to slide along the inner wall of the sliding groove 20. The compression spring 24 is compressed, and its reaction force causes the limiting plate 25 to clamp the transformer body 5. Then, the first hydraulic cylinder 22 is adjusted to clamp the clamping plate 18 above the mounting slot 19, providing a second clamping effect. After the transformer body 5 is installed, the embedding seat 14 moves downwards under its own weight. Then, the cylinder 11 is adjusted to bring the pressure plate 9 into contact with the top of the embedding seat 14, thus limiting the embedding seat 14. As the transformer body 5 operates, the ambient temperature rises. The temperature is monitored by the temperature sensor 2. If the temperature is too high, the cylinder 11 is adjusted to press the pressure plate 9 against the embedding seat 14, causing the embedding seat 14 to press down. The embedded seat 14 squeezes the cooling water inside the cooling seat 3 to both sides, causing the cooling water level on both sides to rise. As the embedded seat 14 presses down, the transformer body 5 descends, increasing the contact area between the condenser tubes 13 on both sides of the cooling seat 3 and the transformer body 5. Under the pressure of the embedded seat 14, the cooling water is poured into the condenser tubes 13. The heat-conducting rod 17 on the outside of the condenser tubes 13 transfers the heat from the transformer surface to the condenser tubes 13, where the cooling water absorbs it, thus achieving contact cooling. After the cooling water absorbs the heat, the heat-absorbing end of the semiconductor refrigeration chip 29 absorbs the heat from the cooling water inside the cooling seat 3 and discharges it through the heat dissipation end. During the process of the heat dissipation end of the semiconductor refrigeration chip 29 discharging the heat, the blower 6 is started. The blower 6 blows a large amount of gas into the blower plate 7, and this gas is blown out from the blower hole 28, thereby driving the heat discharged from the heat dissipation end, causing this part of the heat to flow quickly with the gas, thus moving away from the transformer body 5.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
