Description

[0002] With the development of new energy storage technologies, box-type transformers (box-type transformers), as core equipment in energy storage systems, have become increasingly important. Their operational stability directly impacts both efficiency and safety. The transformer compartment, high-voltage compartment, and low-voltage compartment within the box-type transformer generate significant heat during operation. Failure to dissipate heat promptly can lead to equipment overheating and aging, shortening its lifespan and even causing safety accidents. Therefore, an efficient heat dissipation system is a key technology for box-type energy storage transformers.

Especially in high-temperature conditions, the cooling system's energy consumption can account for over 30% of the equipment's total energy consumption, reducing the overall efficiency of the energy storage system. Furthermore, in remote areas or scenarios without a power grid, where external energy supply is limited, traditional cooling methods are less applicable.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] As an embodiment of the present invention, Figures 1 to 7As shown, the energy-saving box transformer for energy storage described in the present invention includes a box-type transformer main body 1, which is divided into a transformer chamber 3, a high-voltage chamber 4 and a low-voltage chamber 5 by a T-shaped partition. Storage box one 6 and storage box two 7 are installed on the top and bottom of the box-type transformer main body 1 respectively. Storage box two 7 is connected to groundwater through a water pump. Power devices 8 corresponding to the transformer chamber 3, high-voltage chamber 4 and low-voltage chamber 5 are installed on storage box one 6. The power device 8 is connected to a pump body 9. The water inlet of the pump body 9 is connected to the storage box two 7 through a pipeline. The transformer chamber 3, high-voltage chamber 4 and low-voltage chamber 5 are all provided with a heat conducting plate 10 connected to the T-shaped partition 2. The heat conducting plate 10 is provided with a return pipe 11 that connects the storage box one 6 and the groundwater.

[0028] During use, groundwater can be pumped into storage box 2 7 by means of a water pump, and then the power device 8 drives the pump body 9 to work, thereby extracting the water in storage box 2 7 through the pipeline and pumping the water into storage box 1 6; the water entering storage box 1 6 can enter the heat conduction plate 10 through the return pipe 11, thereby cooling the heat conduction plate 10, and relying on the heat conduction plate 10 to achieve the cooling work of the transformer chamber 3, high-pressure chamber 4 and low-pressure chamber 5, ensuring the stable operation of the internal equipment of the transformer chamber 3, high-pressure chamber 4 and low-pressure chamber 5; and the hot air in the transformer chamber 3, high-pressure chamber 4 and low-pressure chamber 5 rises, making it easier to contact with the bottom of storage box 1 6, so as to further cool the air inside the transformer chamber 3, high-pressure chamber 4 and low-pressure chamber 5.

[0029] In order to facilitate the operation of the power device 8, as an embodiment of the present invention, the power device 8 includes a piston cylinder 12 with closed ends and a piston cylinder 2 13 with an open upper end. The lower part of the piston cylinder 2 13 is connected to the upper part of the piston cylinder 12. The lower part of the piston cylinder 12 is located at the top inner side of the box-type transformer body 1. The lower part of the piston cylinder 12 is connected to the heat-conducting sleeve 14. The side of the heat-conducting sleeve 14 is connected to one end of the heat pipe 15. The upper parts of the piston cylinder 12 and the piston cylinder 2 13 both pass through the storage box 16. A gas displacement piston 16 is provided on the inside of the piston cylinder 12. The upper part of the gas displacement piston 16 is connected to the pull rod 17. The inner side of the piston cylinder 2 13 is connected to the sealing piston 18. A crankshaft 19 is provided above the storage box 6. The pull rod 17 and the sealing piston 18 are respectively connected to the crankshaft 19 through the piston connecting rod 20. One end of the crankshaft 19 is connected to the pump body 9.

[0030] When in use, the hot air in the transformer chamber 3, the high-voltage chamber 4 and the low-voltage chamber 5 rises, and the hot air heats the lower end of the piston cylinder 12, and the air in the piston cylinder 12 expands and enters the piston cylinder 2 13. After the air pressure in the piston cylinder 2 13 increases, the sealing piston 18 is driven to move, and the sealing piston 18 drives the crankshaft 19 to rotate through the piston connecting rod 20. At the same time, the crankshaft 19 pulls the air-displacing piston 16 to move through the piston connecting rod 20. When the air-displacing piston 16 moves, it drives the air in the piston cylinder 12 to move, thereby causing the hot air in the piston cylinder 12 to move upward, and at the same time, the cold air at the top of the piston cylinder 12 is squeezed downward; since the piston cylinder 12 is located in the storage box 6, the water in the storage box 6 can be used to press the upper surface of the piston cylinder 12 The lower part of the piston cylinder 12 can quickly cool down, while the lower part of the piston cylinder 12 can quickly absorb the heat from the top of the transformer chamber 3, the high-voltage chamber 4 and the low-voltage chamber 5 through the heat-conducting sleeve 14 and the heat pipe 15, thereby quickly heating the lower part of the piston cylinder 12; after the hot air moves upward inside the piston cylinder 12, it can quickly cool down, thereby quickly reducing the internal air pressure of the piston cylinder 12. After the air pressure of the piston cylinder 12 is reduced, the internal air pressure of the piston cylinder 2 13 connected to the piston cylinder 12 is also reduced, thereby facilitating the downward movement of the sealing piston 18; relying on the work of multiple groups of piston cylinders 12 and piston cylinders 2, the crankshaft 19 can be continuously pulled to operate, thereby facilitating the operation of the pump body 9, thereby relying on the pump body 9 to extract water from the storage tank 2 7 and pump the water into the storage tank 1 6;

[0031] As the temperature in the transformer chamber 3, the high-pressure chamber 4 and the low-pressure chamber 5 increases, the corresponding power unit 8 can automatically adjust the operating efficiency of the crankshaft 19. As the temperature rises, the operating speed of the crankshaft 19 above the transformer chamber 3, the high-pressure chamber 4 and the low-pressure chamber 5 is accelerated, thereby accelerating the pumping speed of the pump body 9 and ensuring the cooling effect of the corresponding transformer chamber 3, the high-pressure chamber 4 and the low-pressure chamber 5; at the same time, the accelerated operating speed of the crankshaft 19 also increases the air movement speed in the piston cylinder 12, thereby further improving the cooling speed of the transformer chamber 3, the high-pressure chamber 4 and the low-pressure chamber 5.

[0032] In order to improve the cooling effect of the upper part of the piston cylinder 12, as an embodiment of the present invention, a water storage box 21 corresponding to the piston cylinder 12 and the piston cylinder 2 13 is provided in the storage box 6. The top of the water storage box 21 is open, and the water outlet of the pump body 9 is connected to the inside of the water storage box 21 through a pipeline.

[0033] During use, after the power device 8 drives the pump body 9 to work, the pump body 9 can draw the water in the storage box 27 into the pump body 9, and then pump it into the water storage box 21 through the water outlet of the pump body 9. The water in the water storage box 21 contacts the upper part of the piston cylinder 12, thereby cooling the upper part of the piston cylinder 12. Cooperating with the heating effect of the bottom of the piston cylinder 12, the temperature difference between the upper and lower ends of the piston cylinder 12 is increased, thereby driving the gas displacement piston 16 and the sealing piston 18 to move, and driving the crankshaft 19 to rotate; after the water in the water storage box 21 overflows, it can enter the storage box 6, and the water entering the storage box 6 can enter the heat sink 23 through the return pipe 11, thereby cooling the heat sink 23, and relying on the heat sink 23 to achieve cooling of the transformer chamber 3, high-voltage chamber 4 and low-voltage chamber 5, ensuring the stable operation of the internal equipment of the transformer chamber 3, high-voltage chamber 4 and low-voltage chamber 5.

[0034] In order to improve the heat dissipation efficiency of the heat dissipation plate 23 , as an embodiment of the present invention, heat dissipation fins are provided on the sides of the heat conducting plate 10 .

[0035] In order to ensure the stable operation of the crankshaft 19, as an embodiment of the present invention, a protective shell 22 corresponding to the crankshaft 19 is provided on the top of the water tank 1, and both ends of the crankshaft 19 pass through the protective shell 22 and are rotatably connected to the protective shell 22.

[0036] In order to improve the cooling effect of the storage box 6, as an embodiment of the present invention, the top of the storage box 6 is provided with heat dissipation areas corresponding to the transformer chamber 3, the high-voltage chamber 4 and the low-voltage chamber 5 respectively, and each heat dissipation area is provided with a plurality of heat dissipation plates 23 connected to the upper surface of the storage box 6, and a blowing structure 24 is provided on one side of the heat dissipation plate 23, and the blowing structure 24 is driven by one end of the crankshaft 19.

[0037] During use, as the temperature in the transformer chamber 3, the high-voltage chamber 4, and the low-voltage chamber 5 rises, the corresponding power device 8 above starts to work. The operation of the power device 8 drives the blowing structure 24 to operate, thereby blowing air into the gap between the heat sink 23, thereby relying on the heat sink 23 to cool the storage box 6, ensuring the cooling effect of the storage box 6;

[0038] Furthermore, the blowing structure 24 and the crankshaft 19 are driven, and when the crankshaft 19 runs at an increased speed, the blowing speed of the blowing structure 24 can be increased, thereby increasing the cooling speed of the heat sink 23 and achieving automatic adjustment of the heat dissipation efficiency of the heat sink 23 .

[0039] In order to ensure the blowing effect of the blowing structure 24, as an embodiment of the present invention, the blowing structure 24 includes an air inlet frame 25, which is fixedly connected to the top of the storage box 6 through a bracket 26. The air inlet frame 25 is rotatably connected to the rotating shaft 27 on the side close to the heat dissipation plate 23, and a belt transmission is arranged between adjacent rotating shafts 27. The rotating shafts 27 are connected to the paddles 28, and one end of a group of rotating shafts 27 is belt-driven to one end of the crankshaft 19 through a pulley.

[0040] When in use, the high temperature of the transformer chamber 3, the high-voltage chamber 4 and the low-voltage chamber 5 drives the corresponding power device 8 to operate, thereby driving the corresponding crankshaft 19 to rotate. After the crankshaft 19 rotates, a group of rotating shafts 27 of the blowing structure 24 are driven to rotate by belt transmission. All the blades 28 are driven to rotate by belt transmission between the rotating shafts 27, thereby relying on the blowing structure 24 to blow air to cool the heat sink 23.

[0041] In order to facilitate the control of the return flow rate of the water body in the return pipe 11, as an embodiment of the present invention, an overflow hole 29 is opened on the side of the water storage box 21, and a pressure shell 30 with an opening facing downward is installed in the water storage box 21. The bottom of the pressure shell 30 is connected to the elastic membrane 31, and an overflow pipe 32 is slidably connected in the return pipe 11. A cylinder 33 is fixedly connected to the bottom of the storage box 6 on one side of the overflow pipe 32, and the output end of the cylinder 33 is connected to the upper end of the overflow pipe 32 through a connecting piece 34. The pressure shell 30 and the cylinder 33 above the transformer chamber 3, the pressure shell 30 and the cylinder 33 above the high-pressure chamber 4, and the pressure shell 30 and the cylinder 33 above the low-pressure chamber 5 are all connected by pipelines.

[0042] During use, as the temperature in the transformer chamber 3, the high-voltage chamber 4 and the low-voltage chamber 5 increases, the power unit 8 starts to operate, thereby driving the pump body 9 to pump water; the pump body 9 pumps the water in the storage box 2 7 into the storage box 1 6 and then into the water storage box 21. The water in the water storage box 21 can cool the upper part of the piston cylinder 12, thereby further increasing the temperature difference between the upper and lower ends of the piston cylinder 12, ensuring the operation effect of the power unit 8; the water in the water storage box 21 can flow into the overflow hole 29. Inside the storage box 6, if the pump body 9 takes in water at a fast speed, the water that does not flow out through the overflow hole 29 in time will overflow through the top of the water storage box 21 into the storage box 6. At the same time, as the water level in the water storage box 21 rises, the air pressure inside the pressure shell 30 increases. Due to the connection between the cylinder 33 and the pressure shell 30, the cylinder 33 can be driven to extend after the air pressure inside the pressure shell 30 increases, and the overflow pipe 32 can be driven to move upward. After the overflow pipe 32 moves upward, the speed at which the water in the storage box 6 enters the overflow pipe 32 decreases.

[0043] If the power unit 8 fails and causes the operation speed to be slow or not running, the water pumping volume decreases at this time, and the water in the water storage box 21 flows out through the overflow hole 29, and the water level in the water storage box 21 drops; after the water level drops, the pressure in the pressure shell 30 decreases. At this time, the cylinder 33 shortens, thereby driving the overflow pipe 32 to move downward; after the overflow pipe 32 moves downward, the water in the storage box 6 can easily enter the overflow pipe 32, thereby increasing the reflux volume of the corresponding return pipe 11; for example, if the power unit 8 corresponding to the transformer chamber 3 fails and causes the operation speed to be slow or not running, the water level in the water storage box 21 above the transformer chamber 3 drops, and the corresponding overflow pipe 32 moves downward, and more water in the storage box 6 overflows through the overflow pipe 32 above the transformer chamber 3, thereby increasing the reflux volume of the return pipe 11 in the transformer chamber 3, which can provide redundant protection to a certain extent and avoid the temperature in the transformer chamber 3 being too high.

[0044] The working principle of the present invention is as follows: after the water pump is started, groundwater is pumped into the storage tank 2 7 to provide a water source for cooling; the hot air in the transformer chamber 3, the high-pressure chamber 4 and the low-pressure chamber 5 rises, heating the lower part of the piston cylinder 12; the hot air expands the air in the piston cylinder 12, and the expanded air enters the piston cylinder 2 13, the air pressure in the piston cylinder 2 13 increases, pushing the sealing piston 18 upward, and the sealing piston 18 drives the crankshaft 19 to rotate through the piston connecting rod 20; the rotation of the crankshaft 19 simultaneously pulls the gas displacement piston 16 upward through the piston connecting rod 20 The air in the piston cylinder 12 moves upward, while the cold air at the top is squeezed downward. The upper part of the piston cylinder 12 is located in the storage box 16, and the water in the storage box 6 quickly cools down, causing the air pressure in the piston cylinder 12 to decrease. The air pressure in the piston cylinder 2 13 connected to the piston cylinder 12 also decreases, which facilitates the downward movement of the sealing piston 18, forming a cycle. Multiple groups of piston cylinders 12 and piston cylinders 2 13 work together to continuously pull the crankshaft 19 to operate, driving the pump body 9 to continuously extract the water in the storage box 2 7 and pump it into the storage box 6;

[0045] The water outlet of the pump body 9 pumps water into the water storage box 21 through the pipeline. The water contacts the upper part of the piston cylinder 12, further increasing the temperature difference between the upper and lower ends of the piston cylinder 12 and enhancing the driving effect of the power device 8.

[0046] The crankshaft 19 drives the rotating shaft 27 of the blowing structure 24 to rotate through the belt drive, and the rotating shaft 27 drives the blades 28 to rotate, blowing air to the gap between the heat sink 23. When the temperature rises, the operating speed of the crankshaft 19 increases, and the blowing speed of the blowing structure 24 increases accordingly, realizing automatic adjustment of the heat dissipation efficiency of the heat sink 23;

[0047] Changes in the pumping speed of the pump body 9 cause changes in the water level in the water storage box 21. When the water level rises, the air pressure in the pressure shell 30 increases; when the water level drops, the air pressure in the pressure shell 30 drops. The pressure shell 30 is connected to the cylinder 33 via a pipeline. The change in air pressure drives the cylinder 33 to expand and contract, causing the overflow pipe 32 to move up and down. Specifically, when the water level in the water storage box 21 rises, the air pressure in the pressure shell 30 increases, the cylinder 33 extends, the overflow pipe 32 moves upward, and the speed at which water enters the return pipe 11 decreases. Conversely, when the water level in the water storage box 21 drops, the air pressure in the pressure shell 30 decreases, the cylinder 33 shortens, the overflow pipe 32 moves downward, and the speed at which water enters the return pipe 11 increases. When the power unit 8 corresponding to a certain chamber fails, the water level in the water storage box 21 above the chamber drops, and the overflow pipe 32 moves downward, increasing the amount of reflux in the return pipe 11 of the chamber and preventing overheating.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention.
