Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, specifically to a heat dissipation mechanism for a fully immersed evaporative cooling transformer. Background Technology
[0002] A fully immersed evaporative cooling transformer is a type of transformer that uses evaporative cooling technology. Among the factors affecting the normal operation of oil-immersed transformers, the impact of heat generation cannot be ignored. Heat generation is a common phenomenon, but it is extremely damaging to oil-immersed transformers. Heat dissipation has always been a key technology for transformers. Currently, most oil-immersed transformers dissipate heat by installing heat dissipation fins on the transformer casing. This heat dissipation method is inefficient. When the transformer is operating under high load and the heat sink cannot effectively dissipate heat, the transformer may burn out. Utility Model Content

[0007] Through the above technical solution, the water receiving plate can recycle the water that has not yet evaporated, thereby realizing the secondary use of water resources, while the filter screen can filter impurities in the water flow.

[0011] As a preferred embodiment of this utility model, the ends of the water receiving plates on the left and right sides away from the openings are respectively connected by two supporting feet, and all four water receiving plates are inclined.
[0012] As a preferred embodiment of this utility model, a U-shaped tube is fitted on the top of the outer side of the transformer body, and connecting frames are fixedly connected to both ends of the four outer walls of the U-shaped tube.

[0014] The above technical solution can spray water onto the heat sink, and the evaporation of water will carry away a large amount of heat, thereby significantly improving the heat dissipation efficiency of the heat sink and enabling it to maintain good working condition even in high-temperature environments.
[0015] As a preferred embodiment of this utility model, a support plate is fixedly connected to the bottom of the water pump, one side of the support plate is fixedly connected to the outer wall of the support foot, and a suction pipe is connected to the flange on the side of the water pump away from the delivery pipe.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.
[0028] For examples, please refer to Figure 1-5 This utility model provides a technical solution:
[0029] A heat dissipation mechanism for a fully immersed evaporative cooling transformer includes a transformer body 1. Support feet 2 are welded to both sides of the bottom of the transformer body 1. Heat dissipation fins 3 are evenly distributed on the vertical surface of the transformer body 1. Heat dissipation components 4 for assisting the heat dissipation of the heat dissipation fins 3 are provided on the top of the outer side of the transformer body 1 and the bottom of the transformer body 1. The heat dissipation components 4 include a water tank 404 disposed between the two support feet 2. Collection components 5 are disposed around the water tank 404 and inside the heat dissipation components 4.
[0030] The collection component 5 includes openings 501 on the top of the four facades of the water tank 404. Water receiving plates 502 penetrate the inner side of each of the four openings 501. A filter screen 503 is installed inside the water tank 404. A connecting frame 504 is fixedly connected to the outer side of the filter screen 503. T-shaped sliders 505 are fixedly connected to the outer walls of both sides of the connecting frame 504. T-shaped grooves 506 are symmetrically opened on the inner walls of both sides of the connecting frame 504. Unevaporated water flows into the water tank 404 through the inclined water receiving plates 502, realizing the recycling of water resources. At the same time, the filter screen 503 filters the return water, effectively removing impurities in the water and ensuring the cleanliness of the circulating water.
[0031] The heat sink 3 is vertically wavy and made of cast aluminum. The outer walls of the two sides of the water tank 404 are fixedly connected to the outer walls of the two support feet 2. The front end of the connecting frame 504 extends to the outside of the water tank 404. The outer wall of the connecting frame 504 is slidably connected to the inner wall of the water tank 404. The two T-shaped sliders 505 are respectively adapted to the two T-shaped grooves 506. The surfaces of the two T-shaped sliders 505 are slidably connected to the inner walls of the two T-shaped grooves 506. The ends of the water receiving plates 502 on the left and right sides away from the openings 501 pass through the two support feet 2. The wavy heat sink 3 can effectively increase the heat dissipation area and improve the heat dissipation efficiency. The wavy heat sink design not only increases the contact area between the heat sink and the air, but also facilitates the airflow between the heat sinks, accelerating the transfer and dissipation of heat. At the same time, the cast aluminum heat sink has good thermal conductivity and can quickly conduct the heat generated by the transformer body to the heat sink.
[0032] All four water receiving plates 502 are inclined. A U-shaped tube 401 is fitted on the top of the outer side of the transformer body 1. Connecting brackets 402 are fixedly connected to both ends of the four outer walls of the U-shaped tube 401. The U-shaped tube 401 is fixedly connected to the outer wall of the transformer body 1 through the connecting brackets 402. Spray heads 403 are evenly distributed at the bottom of the U-shaped tube 401. A conveying pipe 407 is fixedly connected to the middle of one side of the U-shaped tube 401. A water pump 406 is connected to the flange at the end of the conveying pipe 407 away from the U-shaped tube 401. The spray heads 403 at the bottom of the U-shaped tube 401 spray cold water evenly onto the heat sink 3. The cold water evaporates rapidly on the surface of the heat sink 3, absorbing a large amount of heat, thereby significantly reducing the temperature of the heat sink 3.
[0033] A support plate 405 is fixedly connected to the bottom of the water pump 406. One side of the support plate 405 is fixedly connected to the outer wall of the support foot 2. A suction pipe 408 is connected to the flange on the side of the water pump 406 away from the delivery pipe 407. The end of the suction pipe 408 away from the water pump 406 passes through the support foot 2 and is fixedly connected to one side of the water tank 404.
[0034] The water pump 406 uses the extraction pipe 408 and the delivery pipe 407 to extract cold water from the water tank 404 and delivers it to the loop pipe 401 through the delivery pipe 407. The spray head 403 at the bottom of the loop pipe 401 sprays the cold water evenly onto the heat sink 3. The cold water evaporates rapidly on the surface of the heat sink 3, absorbing a large amount of heat, thereby significantly reducing the temperature of the heat sink 3.
[0035] The working process of this utility model is as follows: During use, the heat sink 3 on the surface of the transformer body 1 is wavy, which effectively increases the heat dissipation area and improves heat dissipation efficiency. The wavy design not only increases the contact area between the heat sink and the air but also facilitates airflow between the heat sinks, accelerating heat transfer and dissipation. Simultaneously, the cast aluminum material of the heat sink has excellent thermal conductivity, rapidly transferring the heat generated by the transformer body to the heat sink, further improving the heat dissipation effect. Subsequently, the water pump 406 uses the extraction pipe 408 and the delivery pipe 407 to extract cold water from the water tank 404 and delivers it through the delivery pipe 407. The cold water is evenly sprayed onto the heat sink 3 by the spray head 403 at the bottom of the U-shaped tube 401. The cold water evaporates rapidly on the surface of the heat sink 3, absorbing a large amount of heat, thereby significantly reducing the temperature of the heat sink 3. Some of the evaporated water vapor is carried away by the air, while some flows into the water tank 404 along the inclined water receiving plate 502, realizing the recycling of water resources. At the same time, the filter screen 503 filters the return water, effectively removing impurities in the water and ensuring the cleanliness of the circulating water. The entire heat dissipation mechanism has a compact structure, high heat dissipation efficiency, and can realize the conservation and recycling of water resources, which has high practical value.

Its structure, circuit and control principle are all known existing technologies. Therefore, the structure, circuit and control principle of the water pump 406 will not be described in detail here.
