Description

Technical Field

[0001] This utility model relates to the technical field of cooling structure for power transformers, specifically a cooling structure for a power transformer. Background Technology

[0002] Power transformers are common electrical appliances, used in most household appliances. However, traditional power transformers generate a lot of heat during installation and use. If this heat cannot be absorbed or dissipated, it will affect the lifespan of the power transformer and shorten its service life. Existing devices still have some defects; for example.

[0003] For example, a cooling structure for a power transformer, as described in announcement number CN221861397U, includes a power transformer body, a first exhaust frame, a second exhaust frame, and air vents. The power transformer body has a limiting insertion hole containing a limiting rod, which is fixedly connected to the first exhaust frame. The first exhaust frame has an exhaust vent connected to an exhaust channel, which contains a vacuum pump. The second exhaust frame has air vents. While this device can effectively cool the power transformer, it typically relies on air cooling when the transformer temperature is too high, resulting in low cooling efficiency. It is not suitable for rapidly cooling transformers at excessively high temperatures. Therefore, we propose a cooling structure device for power transformers to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling structure for a power transformer, so as to solve the problem that the cooling structure for power transformers mentioned in the background art is not convenient for quickly cooling the transformer when the temperature is too high.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling structure for a power transformer, comprising a transformer body and a heat-conducting plate;

[0006] The transformer body is connected to a heat-conducting plate via a snap-fit ​​connection mechanism. The heat-conducting plate is fixedly connected to a fixed plate via a connecting rod. A fan is installed inside the fixed plate. A first water storage tank is installed inside the fixed plate, and a water pump is installed inside the first water storage tank. The water pump is connected to a water pumping pipe. The front end of the water pumping pipe is connected to a cooling pipe, which is located inside the heat-conducting plate. One end of the cooling pipe is connected to a return water pipe. The return water pipe is connected to a second water storage tank, which is located inside the fixed plate and is connected to the first water storage tank.

[0007] As a preferred technical solution of this utility model, the engaging connection mechanism includes a transformer body, a heat-conducting plate, a locking block, a stop block, and a spring. The heat-conducting plate is fixedly connected to the inside of the spring, and the front end of the spring is fixedly connected to the stop block. The stop block and the locking block engage, and the locking block is fixedly connected to the surface of the transformer body.

[0008] As a preferred technical solution of this utility model, the heat-conducting plate is made of a high thermal conductivity material, and the heat-conducting plate is symmetrically arranged about the center of the transformer body, and the heat-conducting plate is connected to the transformer body through a snap-fit ​​connection mechanism.

[0009] As a preferred embodiment of this utility model, the refrigeration pipe is S-shaped, and the lower part of the refrigeration pipe is connected to the water pumping pipe, while the upper end of the refrigeration pipe is connected to the water return pipe.

[0010] As a preferred embodiment of this utility model, the fan is symmetrically arranged about the center of the fixed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The cooling structure of the power transformer is equipped with a cooling mechanism. During use, the heat-conducting plate is installed through a snap-fit ​​connection mechanism. When the transformer body generates temperature during use, the heat generated by the transformer body can be conducted away through the heat-conducting plate made of high thermal conductivity material. At the same time, the fan inside the fixing plate blows the surrounding air to the heat-conducting plate, and the heat is carried away by the heat-conducting plate, increasing the heat dissipation efficiency. When the transformer body temperature is too high, the coolant in the first water storage tank can be pumped into the water pumping pipe and then into the cooling pipe through the water pumping pump, further carrying away the heat and enhancing the cooling effect. At this time, the coolant enters from the bottom of the cooling pipe, flows to the top, and then enters the return water pipe and then into the second water storage tank. Since the second water storage tank and the first water storage tank are interconnected, the coolant continuously circulates, resulting in a better cooling effect and achieving rapid cooling of the transformer body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a cooling structure for a power transformer, including a transformer body 1 and a heat-conducting plate 2. The side of the transformer body 1 is connected to the heat-conducting plate 2 via a snap-fit ​​connection mechanism. The snap-fit ​​connection mechanism includes the transformer body 1, the heat-conducting plate 2, a snap block 3, a stop block 4, and a spring 5. The heat-conducting plate 2 is fixedly connected to the inside of the spring 5, and the front end of the spring 5 is fixedly connected to the stop block 4. The stop block 4 and the snap block 3 are snapped together. The snap block 3 is fixedly connected to the surface of the transformer body 1. The heat-conducting plate 2 is fixedly connected to a fixed plate 7 via a connecting rod 6. A fan 8 is provided inside the fixed plate 7. The fan 8 is symmetrically arranged about the center of the fixed plate 7. The heat-conducting plate 2 is made of a high thermal conductivity material and is symmetrically arranged about the center of the transformer body 1. All heat-conducting plates 2 are connected to the transformer body 1 via the snap-fit ​​connection mechanism.

[0019] When in use, align the slot on the surface of the heat-conducting plate 2 with the slot 3 on the surface of the transformer body 1 and insert it so that the slot 3 and the stop 4 connected by the spring 5 inside the heat-conducting plate 2 are engaged, thus completing the installation of the heat-conducting plate 2. At this time, coolant is added into the second water tank 14 through the water inlet on the surface of the second water tank 14 so that the first water tank 9 and the second water tank 14 are filled with coolant. When the transformer body 1 generates temperature during use, the heat generated by the transformer body 1 can be conducted away by the heat-conducting plate 2 made of high thermal conductivity material. At the same time, the fan 8 inside the fixing plate 7 is activated to blow the surrounding air to the heat-conducting plate 2, and the heat is carried away by the heat-conducting plate 2, increasing the heat dissipation efficiency and thus helping the transformer to dissipate heat faster.

[0020] The fixed plate 7 is provided with a first water storage tank 9, and a water pump 10 is provided inside the first water storage tank 9. The water pump 10 is connected to a water pump pipe 11. The front end of the water pump pipe 11 is connected to a cooling pipe 12. The cooling pipe 12 is located inside the heat conduction plate 2. One end of the cooling pipe 12 is connected to a return water pipe 13. The cooling pipe 12 is S-shaped. The lower end of the cooling pipe 12 is connected to the water pump pipe 11, and the upper end of the cooling pipe 12 is connected to the return water pipe 13. The return water pipe 13 is connected to a second water storage tank 14. The second water storage tank 14 is located inside the fixed plate 7 and is connected to the first water storage tank 9.

[0021] When the temperature of the transformer body 1 is too high, the coolant inside the first water storage tank 9 can be pumped into the water pumping pipe 11 by the water pump 10 and then into the cooling pipe 12. At this time, the coolant flows inside the S-shaped cooling pipe 12, further removing heat and enhancing the cooling effect. The temperature of the coolant is usually lower than the air temperature, so it can more effectively reduce heat. At this time, the coolant enters from the bottom of the cooling pipe 12, flows to the top, and then enters the return water pipe 13 and then enters the second water storage tank 14. Since the second water storage tank 14 and the first water storage tank 9 are interconnected, the coolant is continuously pumped out from the first water storage tank 9 and enters the cooling pipe 12 and then returns to the second water storage tank 14, so that the coolant is constantly circulating, making the cooling effect better and completing the rapid cooling of the transformer body 1.

[0022] Working principle: When using the cooling structure of the power transformer, align the slot on the surface of the heat-conducting plate 2 with the slot 3 on the surface of the transformer body 1 and insert it. The slot 3 and the stop 4 connected by the spring 5 inside the heat-conducting plate 2 will engage, completing the installation of the heat-conducting plate 2. At this time, coolant is added through the water inlet on the surface of the second water tank 14, filling both the first and second water tanks 9 with coolant. When the transformer body 1 generates heat during use, the heat-conducting plate 2, made of high thermal conductivity material, can conduct the heat away. Simultaneously, the fan 8 inside the fixing plate 7 blows surrounding air to the heat-conducting plate 2, which then carries away the heat, increasing heat dissipation efficiency and helping the transformer dissipate heat faster. When the temperature of the transformer body 1 becomes too high, the water pump 10 can be used to drain the water from the first water tank 9. After the coolant is drawn into the pumping pipe 11, it enters the cooling pipe 12. At this time, the coolant flows inside the S-shaped cooling pipe 12, further carrying away heat and enhancing the cooling effect. The temperature of the coolant is usually lower than the air temperature, so it can more effectively reduce heat. The coolant enters from the bottom of the cooling pipe 12, flows to the top, and then enters the return pipe 13 and then the second water storage tank 14. Since the second water storage tank 14 and the first water storage tank 9 are interconnected, the coolant is continuously drawn from the first water storage tank 9 and enters the cooling pipe 12 before returning to the second water storage tank 14, so that the coolant is continuously circulating, which makes the cooling effect better and completes the rapid cooling of the transformer body 1, thereby completing a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
