Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more specifically, to a high-efficiency heat dissipation and ventilation design device for transformers. Background Technology

[0002] A transformer is a static electromagnetic energy conversion device that undertakes critical tasks such as voltage transformation, power distribution, and electrical isolation. Its reliability, efficiency, and economy directly affect the safety and stability of the entire power grid. Among these, efficient heat dissipation is a crucial condition for a transformer to maintain stable operation.

[0003] Existing transformers typically rely on fins mounted on the outside of the transformer for natural heat dissipation. However, during the hot summer months, coupled with peak electricity demand, the high load operation of the transformer makes natural heat dissipation from the fins insufficient to meet operational needs. Therefore, workers usually spray water onto the transformer fins continuously to cool them down. However, continuous water spraying causes the humidity in the surrounding environment to rise continuously. When the humidity reaches a high level, the evaporation efficiency of water decreases significantly, resulting in a significant reduction in the transformer's heat dissipation effect. Furthermore, the accumulation of a large amount of water on the ground near the transformer can maintain this high humidity state for a long time, seriously affecting the transformer's normal heat dissipation performance. Summary of the Invention

[0004] The present invention provides a high-efficiency heat dissipation and ventilation design device for transformers, which aims to solve the following problem: In existing transformers, during the peak electricity consumption period in summer, spraying water onto the transformer fins to cool them down will cause the air humidity in the surrounding environment of the transformer to rise continuously. When the humidity reaches a high level, the evaporation efficiency of water will be greatly reduced, thereby significantly reducing the heat dissipation effect of the transformer.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer high-efficiency heat dissipation and ventilation design device, comprising: The transformer body has a set of heat dissipation fins around its four sides. Each heat dissipation fin has several individual heat dissipation fins arranged vertically and in an array. The transformer body is equipped with a cooling mechanism, which includes a bracket on the transformer body, a rotating shaft and a drive assembly on the bracket, the drive assembly for driving the rotating shaft to rotate, and a cleaning assembly on the rotating shaft. The cleaning assembly includes several cleaning modules, each of which contacts the surface of a corresponding heat sink fin, and the cleaning modules are made of water-absorbing material. A cleaning tank is located below the transformer body. The cleaning tank contains purified water and several sets of squeezing rods, which are used to squeeze the cleaning module.

[0006] In a preferred embodiment, a fan assembly is provided on the transformer body, and the fan assembly is located above the corresponding heat dissipation fins.

[0007] In a preferred embodiment, a rectangular frame is provided on the rotating shaft, a slide rod is provided on the rectangular frame, and several cleaning components are respectively sleeved on corresponding mounting rods on the slide rod. A spring is sleeved on the slide rod and the spring is located inside the corresponding rectangular frame.

[0008] In a preferred embodiment, the transformer body is provided with an adjustment mechanism for adjusting the telescopic length of the cleaning component relative to the rectangular frame.

[0009] In a preferred embodiment, the adjustment mechanism includes a brushing section parallel to the corresponding heat dissipation fins. When the slide rod rotates in contact with the brushing section, several cleaning components fully contact the corresponding heat dissipation fins.

[0010] In a preferred embodiment, a shaking section is provided at the bottom of the scrubbing section, and a number of protruding balls are arranged in an array on the shaking section. When the slide rod rotates in contact with the shaking section, the number of cleaning components continuously shake.

[0011] In a preferred embodiment, a recovery section is provided at the bottom of the shaking section. When the slide rod rotates in contact with the recovery section, the cleaning component continuously retracts until the cleaning component is completely inside the water storage area of ​​the cleaning tank.

[0012] In a preferred embodiment, a cleaning section is provided at the end of the recovery section away from the shaking section. When the slide bar rotates in contact with the recovery section, the cleaning component continues to rotate and is completely immersed in the purified water.

[0013] In a preferred embodiment, a squeezing section is provided at the bottom of the cleaning section. When the slide rod rotates in contact with the squeezing section, the cleaning component retracts to a position that matches the squeezing rod.

[0014] In a preferred embodiment, when the slide bar rotates in contact with the vibrating section, the cleaning component is offset from the position of the cleaning pool in the vertical direction.

[0015] The beneficial effects of this invention are as follows: 1. By setting up a cooling mechanism in conjunction with a fan assembly, this invention can significantly improve the heat dissipation capacity of the transformer body while avoiding creating a high humidity environment around the transformer. This effectively ensures the long-term stable heat dissipation effect of the transformer's heat dissipation fins, while greatly reducing the required water source and achieving good performance. 2. This invention utilizes a cleaning component to evaporate water film onto the transformer heat sink fins while simultaneously clearing and cleaning the gaps between the heat sink fins, effectively ensuring smooth airflow on the surface of the heat sink fins and significantly extending their service life. 3. This invention utilizes the cooperation between the sliding rod and the convex ball on the shaking section to continuously shake the cleaning component while it rotates, thereby effectively shaking off and removing any debris that may be attached to the cleaning component, avoiding secondary contamination of the heat sink fins by the cleaning component, and ensuring the cleaning effect.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Compared to water spraying for heat dissipation, the heat dissipation rate by utilizing the vaporization and evaporation of water can be more than 10 times that of flowing water absorbing heat.

[0020] Example 1 Refer to the instruction manual appendix Figure 1 and Figure 7This embodiment proposes a high-efficiency heat dissipation and ventilation design device for transformers to solve the problem in the prior art where, during peak electricity consumption periods in summer, spraying water onto the transformer fins for cooling leads to a continuous increase in the humidity of the air surrounding the transformer. When the humidity reaches a high level, the evaporation efficiency of the water decreases significantly, resulting in a significant reduction in the heat dissipation effect of the transformer. The device includes: The transformer body 1 has a set of heat dissipation fins 2 arranged around its perimeter. Several heat dissipation fins 2 in each set of heat dissipation fins 2 are arranged vertically and in an array. It should be noted that, depending on the actual specifications of the transformer, the number of individual heat dissipation fins 2 in each group of heat dissipation fins 2 will also be increased or decreased accordingly. In order to maximize the heat dissipation effect, the number of individual heat dissipation fins 2 is generally set as much as possible. Therefore, the distance between two adjacent heat dissipation fins 2 is generally small, for example, about 5 cm.

[0021] A cooling mechanism 3 is provided on the transformer body 1. The cooling mechanism 3 includes a bracket 31 provided on the transformer body 1. A rotating shaft 32 and a drive assembly 33 are provided on the bracket 31. The drive assembly 33 is used to drive the rotating shaft 32 to rotate. A cleaning assembly 36 is provided on the rotating shaft 32. The cleaning assembly 36 includes several cleaning modules. The several cleaning modules respectively contact the surface of the corresponding heat dissipation fins 2, and the cleaning modules are made of water-absorbing material. It should be noted that the drive component 33 is a motor, and the cleaning module can be made of materials such as water-absorbing sponge and water-absorbing fiber. Furthermore, the size of the cleaning module is adapted to the spacing of the heat dissipation fins 2, which ensures that both sides of the heat dissipation fins 2 can fully contact the cleaning module.

[0022] A cleaning tank 4 is provided below the transformer body 1. The cleaning tank 4 contains purified water and is equipped with several sets of squeezing rods 41, which are used to squeeze the cleaning module.

[0023] It should be noted that the size of the squeezing rod 41 is adapted to the cleaning module, that is, to ensure that when the cleaning module passes through the corresponding squeezing rod 41, the squeezing rod 41 squeezes and drains the cleaning module to a certain extent.

[0024] In this embodiment, the specific implementation scenario is as follows: when the natural heat dissipation of the heat sink fins 2 is insufficient to meet the operating pressure of the transformer, the drive component 33 can be activated, thereby driving the cleaning component 36 to rotate downward along the top of the heat sink fins 2. While rotating, the water adsorbed on the cleaning component 36 will form a thin "water film" on the surface of the heat sink fins 2. This "water film" will evaporate quickly after absorbing the heat of the heat sink fins 2, thereby quickly cooling the heat sink fins 2. Then, the cleaning component 36 continues to rotate into the cleaning tank 4, thereby being able to absorb water again, and squeezing out some water while passing through the squeezing rod 41. This ensures that the water adsorbed by the cleaning component 36 is sufficient to form a "water film" on the surface of the heat sink fins 2, without dripping everywhere and wasting water.

[0025] A fan assembly 6 is provided on the transformer body 1, and the fan assembly 6 is located above the corresponding heat dissipation fins 2.

[0026] It should be noted that by setting the fan assembly 6 above the heat dissipation fins 2, the evaporation rate of the "water film" on the surface of the heat dissipation fins 2 can be further accelerated, thereby further improving the heat dissipation effect of the heat dissipation fins 2. Furthermore, the fan assembly 6 blows the evaporated moisture away from the area around the transformer body 1, so that the area around the transformer body 1 can maintain a low humidity state for a long time to ensure stable evaporation of moisture.

[0027] Example 2 Based on Embodiment 1, this embodiment proposes a cooling mechanism 3 to solve the problem in the prior art that the gaps between the densely arranged heat dissipation fins 2 are prone to accumulating biomass such as fallen leaves and willow catkins, which will affect the smooth flow of air on the surface of the heat dissipation fins 2 and affect the heat dissipation effect. Furthermore, after a long period of time, the organic acids and other corrosive substances produced by the decomposition of organic biomass will also corrode the coating on the surface of the heat dissipation fins 2, thereby affecting the service life of the heat dissipation fins 2.

[0028] A rectangular frame 34 is provided on the rotating shaft 32, and a slide rod 35 is provided on the rectangular frame 34. Several cleaning components 36 are respectively sleeved on the corresponding mounting rods on the slide rod 35. A spring 37 is sleeved on the slide rod 35 and the spring 37 is located inside the corresponding rectangular frame 34.

[0029] It should be noted that the cleaning component 36 and the corresponding mounting rod on the slide bar 35 are detachably connected and can be connected by means of threads or screws. This is a mature technology well known to those skilled in the art and will not be described in detail in this embodiment. The cleaning component 36 is a universal part, which is easy to replace when damaged. Furthermore, some common methods for cleaning heat sink fins 2 involve using a scraper to repeatedly scrape the surface of the heat sink fins 2. This can easily cause organic matter such as leaves that may be stuck to the surface of the heat sink fins 2 to be ground and smeared on the surface of the heat sink fins 2. As a result, the heat sink fins 2 cannot be cleaned properly, and the residual organic matter will also affect the heat dissipation effect of the heat sink fins 2.

[0030] An adjustment mechanism 5 is provided on the transformer body 1. The adjustment mechanism 5 is used to adjust the extension length of the cleaning component 36 relative to the rectangular frame 34.

[0031] It should be noted that by cooperating with the adjustment mechanism 5 through the slide bar 35, the length of the cleaning component 36 relative to the rectangular frame 34 can be adjusted in real time according to the actual position to which the cleaning component 36 rotates, so as to meet the requirements of the cleaning component 36 to clean and wet the heat dissipation fins 2, and to fully immerse the cleaning component 36 in the cleaning pool 4 for water absorption and cleaning.

[0032] Example 3 Based on Embodiment 2, this embodiment proposes an adjustment mechanism 5 to solve the problem in the prior art that the surface of the cleaning component 36 used to clean the heat sink fins 2 is easily covered with debris such as leaves and lint, which leads to secondary contamination of the surface of the heat sink fins 2 during subsequent cleaning.

[0033] The adjustment mechanism 5 includes a brushing section 51, which is parallel to the corresponding heat dissipation fins 2. When the slide rod 35 rotates in contact with the brushing section 51, several cleaning components 36 fully contact the corresponding heat dissipation fins 2.

[0034] It should be noted that when the cleaning component 36 is in contact with the brushing section 51, the cleaning component 36 is always positioned so as to be in full contact with the heat sink fins 2 without interfering with the transformer body 1.

[0035] The bottom of the scrubbing section 51 is provided with a shaking section 52, on which several protruding balls 53 are arranged in an array. When the slide rod 35 rotates in contact with the shaking section 52, several cleaning components 36 continuously shake.

[0036] It should be noted that the actual length and tilt angle of the shaking section 52 can be adjusted according to the actual size of the cleaning component 36 and the washing pool 4 to ensure that the cleaning component 36 has enough shaking time to fully shake off impurities.

[0037] The bottom of the shaking section 52 is provided with a recovery section 54. When the slide bar 35 rotates in contact with the recovery section 54, the cleaning component 36 continuously retracts until the cleaning component 36 is completely inside the water storage area of ​​the cleaning pool 4.

[0038] It should be noted that the actual length and tilt angle of the recycling section 54 can be adjusted according to the actual dimensions of the cleaning component 36 and the cleaning tank 4 to ensure that the cleaning component 36 does not interfere with the cleaning tank 4 when it enters the cleaning tank 4.

[0039] A cleaning section 55 is provided at the end of the recovery section 54 away from the shaking section 52. When the slide bar 35 rotates in contact with the recovery section 54, the cleaning component 36 rotates continuously and is completely immersed in the purified water.

[0040] It should be noted that the actual length and tilt angle of the cleaning section 55 can be adjusted according to the actual size of the cleaning component 36 and the cleaning pool 4 to ensure that the cleaning component 36 can fully contact the water when entering the cleaning pool 4, so as to ensure the water absorption effect.

[0041] The bottom end of the cleaning section 55 is provided with a squeezing section 56. When the slide rod 35 rotates in contact with the squeezing section 56, the cleaning component 36 retracts to a position that matches the squeezing rod 41.

[0042] It should be noted that the actual length and tilt angle of the squeezing section 56 can be adjusted according to the actual dimensions of the cleaning component 36 and the cleaning tank 4, so as to ensure that the cleaning tank 4 will not interfere with the rotation of the cleaning component 36 when the cleaning component 36 is detached from the cleaning tank 4.

[0043] When the slide bar 35 rotates in contact with the shaking section 52, the cleaning component 36 is offset from the position of the cleaning pool 4 in the vertical direction.

[0044] It should be noted that when the cleaning component 36 is continuously shaking, its vertical alignment with the cleaning tank 4 can prevent impurities from falling into the cleaning tank 4, thereby effectively extending the service life of the cleaning tank 4.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
