[0002] In modern power systems, transformers are key equipment for realizing electric energy transmission and conversion. The performance of transformers plays a decisive role in the stable operation and efficiency improvement of power systems. With the continuous growth of electricity demand and the development of power equipment towards high power and high density, transformers will generate a lot of heat during operation. Heat dissipation has become a key factor restricting transformer performance and service life.

[0017] (III) Beneficial effects

[0018] The present invention provides an energy-saving transformer with a circulating heat dissipation structure. It has the following beneficial effects:

[0019] (I) This energy-saving transformer with a circulating heat dissipation structure adopts four groups of cooling plates by setting cooling components, and is internally provided with structures such as hot flow grooves, cold flow grooves, connecting grooves and guide grooves. Low-temperature coolant flows into the cold flow grooves through the guide grooves, and quickly absorbs the heat of the transformer body under the action of the heat conduction plates. Then, the coolant enters the hot flow grooves through the connecting grooves according to the principle of rising hot fluid in convection heat exchange, and finally flows out through the return pipe. This design enables the coolant to fully contact the heating parts of the transformer body, improves the heat exchange efficiency, and can more effectively take away the heat generated by the transformer, ensuring that the transformer operates stably at a lower temperature.

[0020] (ii) This energy-saving transformer with a circulating heat dissipation structure increases the heat dissipation area by setting a heat exchange component. The heat dissipation fins on the outer wall of the heat dissipation plate increase the heat dissipation area. The heat of the coolant is transferred to the surface through the heat conduction of the heat dissipation plate and the heat dissipation fins, and then dissipated through the convection heat exchange and radiation heat exchange of the air. At the same time, the ventilation slots enhance the convection of the air, further speeding up the heat dissipation speed, thereby effectively reducing the temperature of the coolant and ensuring the efficient operation of the entire heat dissipation system.

[0021] (III) This energy-saving transformer with a circulating heat dissipation structure has a self-cleaning function by setting a filter assembly. The rotating tube drives the hose to rotate, and the coolant is thrown out and hits the filter plate, which accelerates the filtering speed of the coolant. At the same time, it can also prevent the filter plate from being blocked to a certain extent. Moreover, when the filter plate accumulates certain impurities and needs to be cleaned, only a simple operation of the installation pressure plate is required to remove the baffle shell and the filter plate for replacement, which is convenient for maintenance, ensures the normal operation of the filter assembly, and thus improves the reliability of the entire heat dissipation system.

[0022] (IV) This energy-saving transformer with a circulating heat dissipation structure is provided with a pumping component. The water pump impeller in the pumping component pressurizes the coolant according to the Bernoulli equation in fluid mechanics, thereby providing the power required for the circulation of the coolant. At the same time, the rotating tube in the filter component drives the hose to rotate to increase the flow rate of the coolant, assisting the circulation speed of the circulation component, making the entire coolant circulation system smoother, reducing the power consumption of the pumping component, and further achieving energy-saving effects.

[0041] The heat exchange assembly 6 includes a heat sink 64, which is provided with two groups. The outer wall of each group of heat sinks 64 is fixedly connected with heat fins 63, and the heat fins 63 are arranged in a linear array along the outer wall of the heat sink 64. The inner wall of each group of heat sinks 64 is fixedly connected with a heat dissipation outlet pipe 66, and one end of the heat dissipation outlet pipe 66 away from the heat sink 64 is fixedly connected to the water inlet main pipe 61, and one end of the heat dissipation outlet pipe 66 away from the water inlet main pipe 61 is fixedly connected to the heat dissipation inlet pipe 65, and the inner wall of the water inlet main pipe 61 is fixedly connected with a guide pipe 62.

[0042] The energy-saving transformer is mainly composed of a transformer body 1, a cooling component 4, and an integrated component 3, wherein the integrated component 3 includes a circulation component 5, a heat exchange component 6, a pumping component 7, and a filtering component 8. The components cooperate with each other to form a closed-loop circulation heat dissipation system to ensure that the heat generated by the transformer body 1 during operation can be dissipated promptly and effectively.

[0043] The cooling component 4 is composed of four groups of cooling plates 45 and connecting angle plates 43. A mounting plate 44 is fixedly connected to the top of each group of cooling plates 45. The inner walls of the mounting plate 44 are respectively fixedly connected to the water inlet pipe 41 and the water return pipe 42. The inner walls on both sides of the cooling plate 45 are fixedly connected to the heat conducting plate 46. A hot flow groove 49 is opened in the top wall of the cooling plate 45, a cold flow groove 48 is opened in the bottom wall, and a connecting groove 47 and a guide groove 410 are also opened in the wall.

[0044] When the transformer body 1 generates heat during operation, low-temperature coolant flows in from the water inlet pipe 41, first enters the guide groove 410, and flows to the cold flow groove 48 through the guide groove 410. Since the heat conducting plate 46 is tightly fitted to the surrounding heating parts inside the transformer body 1, according to the principle of heat conduction, the heat is quickly transferred to the coolant, so that the temperature of the coolant is increased. The heated coolant, using the principle of rising hot fluid in convection heat exchange, flows upward through the connecting groove 47 to the hot flow groove 49. Finally, the heated coolant flows out of the cooling component 4 through the return pipe 42, completing a heat exchange process.

[0045] In this process, the good thermal conductivity of the heat conducting plate 46 is key, as it can quickly transfer the heat of the transformer body 1 to the coolant. The flow of the coolant in the cooling plate 45 is based on the principle of convection heat transfer, and the heat is taken away by the flow of the coolant to achieve cooling of the transformer body 1.

[0046] The circulation component 5 plays a role in driving the circulation of the coolant in the entire heat dissipation system. It includes a first water inlet branch 53, a first water inlet conduit 52, a first water return branch 54, a first water return conduit 51, a second water inlet branch 58, a second water return branch 59, a second water inlet conduit 55, a second water return conduit 56, and rings connecting the various components. In addition, it is also connected to the pumping component 7, the filtering component 8 and the heat exchange component 6.

[0047] The heated coolant flowing out from the return pipe 42 of the cooling component 4 enters the pumping assembly 7 through the first return pipe 51 and the first return branch pipe 54. At the same time, the heated coolant in the other two groups of cooling plates 45 also enters the pumping assembly 7 through the second return pipe 42 and the second return branch pipe 59. The water pump impeller 72 in the pumping assembly 7 rotates under the drive of the bottom motor. According to the Bernoulli equation in fluid mechanics, the rotation of the water pump impeller 72 increases the kinetic energy and pressure energy of the coolant, pressurizes the coolant, and obtains sufficient power.

[0048] The pressurized coolant flows into the filter assembly 8 through the connecting conduit 510 to filter impurities. After the cooling liquid is filtered, two groups of cooling plates 45 transport the cooling liquid back to the water inlet pipe 41 through the second water inlet branch pipe 58 and the second water inlet conduit 55, and the other two groups of cooling plates 45 introduce the cooling liquid through the first water inlet branch pipe 53 and the first water inlet conduit 52, thereby completing the circulation of the cooling liquid.

[0049] The water pump impeller 72 in the pumping shell 71 is connected to the bottom motor through the first connecting column 74 and the connecting shaft 75, so that it rotates under the drive of the motor to pressurize the coolant so that it obtains sufficient power. The pressurized coolant in the first fixed shell 73 flows into the filter component 8 through the connecting conduit 510 to filter impurities. The filtered coolant is re-delivered back to the cooling component 4 through the second water inlet branch pipe 58 and the second water inlet conduit 55, among which the water inlet pipes 41 on two groups of cooling plates 45, and the other two groups of cooling plates 45 introduce the filtered coolant through the first water inlet branch pipe 53 and the first water inlet conduit 52 to complete the circulation of the coolant. The working principle of the circulation component 5 is mainly based on the Bernoulli equation in fluid mechanics. The rotation of the water pump impeller 72 increases the kinetic energy and pressure energy of the coolant, so that the coolant can flow in the pipeline. Before using the circulation component 5, it is necessary to open the liquid inlet pipe 57 and inject coolant from the liquid inlet pipe 57 until the coolant emerges from the liquid outlet pipe 512.

[0050] The heat exchange component 6 is composed of two groups of heat sinks 64, each group of heat sinks 64 has a heat sink fin 63 fixedly connected to the outer wall, a heat sink outlet pipe 66 and a heat sink inlet pipe 65 fixedly connected to the inner wall, a water inlet main pipe 61 is connected to the heat sink outlet pipe 66, the heat sink inlet pipe 65 is connected to the filter component 8 through a water pipe 511, a guide pipe 62 is also fixedly connected to the inner wall of the water inlet main pipe 61, and a ventilation groove 67 is opened in the wall of the heat sink 64.

[0051] The coolant flowing out of the water pipe 511 of the filter assembly 8 enters the heat dissipation inlet pipe 65. Since the heat dissipation inlet pipe 65 and the heat dissipation outlet pipe 66 are both located in the heat dissipation plate 64, and the heat dissipation fins 63 are provided on the heat dissipation plate 64, the heat of the coolant is transferred to the surface through heat conduction between the heat dissipation plate 64 and the heat dissipation fins 63. At the same time, the ventilation grooves 67 on the heat dissipation plate 64 facilitate the flow of air, thereby accelerating the dissipation of heat.

[0052] During the heat exchange process, the heat of the coolant is transferred to the outside air through the heat dissipation fins 63. The heat dissipation fins 63 increase the heat dissipation area and improve the heat dissipation efficiency. The temperature of the coolant after heat exchange is reduced, and the contact area with the air is increased through the ventilation grooves 67 and the heat dissipation fins 63, which further accelerates the cooling speed of the coolant in the heat dissipation inlet pipe 65 and the heat dissipation outlet pipe 66. The cooled coolant is gathered in the water inlet main pipe 61 through the heat dissipation outlet pipe 66, and then enters the second water inlet branch pipe 58 and the first water inlet branch pipe 53 through the guide pipe 62.

[0053] The heat exchange component 6 uses the principles of heat conduction, convection heat exchange and radiation heat exchange. The heat of the coolant is first transferred to the surface of the heat sink 64 and the heat sink fins 63 through heat conduction, and then the heat is dissipated to the external environment through convection heat exchange and radiation heat exchange of the air. The design of the ventilation groove 67 is to enhance the convection of the air and further improve the heat dissipation effect.

[0054] The filter assembly 8 includes a filter housing 81 , a mounting plate 82 , a guide wheel 83 , a retaining shell 89 , a filter plate 811 , a rotating tube 88 , a hose 810 , a second fixed shell 86 , a second connecting column 87 , a rotating shaft 85 and a sleeve shaft 84 .

[0055] The coolant flows from the connecting conduit 510 of the circulation assembly 5 into the second fixed shell 86. The motor on the top of the second fixed shell 86 drives the rotating shaft 85 to rotate through the sleeve shaft 84. The rotating shaft 85 is connected to the rotating tube 88 through the second connecting column 87, thereby driving the rotating tube 88 to rotate. During the rotation process, the rotating tube 88 synchronously drives the hose 810 to rotate. Since the hose 810 is made of elastic material, under the drive of the rotating tube 88, the hose 810 performs a circular motion with the rotating tube 88 as the center, and the coolant flowing into the hose 810 is thrown out.

[0056] According to the principle of centrifugal force, the thrown coolant hits the filter plate 811, which on the one hand accelerates the speed of the coolant passing through the filter plate 811, and on the other hand, the tiny pores on the filter plate 811 can intercept impurities in the coolant, such as metal debris, dirt, etc., thereby filtering the coolant. At the same time, this method increases the flow rate of the coolant in the rotating tube 88, and assists the circulation speed of the circulation component 5.

[0057] As time goes by, a certain amount of impurities will accumulate on the filter plate 811 and need to be cleaned. At this time, just grab the handle on the mounting plate 82 and lift the mounting plate 82 upwards. The rotating shaft 85 will slide into the sleeve shaft 84 to provide moving space for the mounting plate 82. Then the retaining shell 89 and the filter plate 811 can be taken out, replaced with a new retaining shell 89 and replaced on the guide wheel 83, and then the force on the mounting plate 82 is released. Under the action of gravity of the mounting plate 82, the mounting plate 82 is pressed onto the filter housing 81 again.

[0058] When the transformer body 1 starts to work and generate heat, the coolant in the cooling component 4 absorbs heat through heat exchange, and the temperature rises. The heated coolant enters the circulation component 5, and under the action of the pumping component 7, it is filtered for impurities by the filtering component 8 and the heat is dissipated by the heat exchange component 6 in sequence, and the temperature drops. The cooled coolant is filtered again by the filtering component 8 and flows back to the cooling component 4 to continue to absorb the heat generated by the transformer body 1. This cycle is repeated to achieve continuous heat dissipation of the transformer body 1.
