An automatic heat dissipation transformer

Abstract

This invention relates to the field of self-cooling transformers, specifically an automatic cooling transformer, comprising a large intelligent transformer and detachable anti-collision sleeves mounted on both sides of the large intelligent transformer. Two sets of transformer oil tanks are fixedly installed on the inner walls of the upper and lower sides of the anti-collision sleeves. A motor is fixedly installed on the inner wall of the bottom of the anti-collision sleeves. A transmission pressing rod is movably sleeved on the inner wall of the transformer oil tank, and lower pressure plates are fixedly installed at both ends of the transmission pressing rod. When cooling oil enters the core winding, the impact of the cooling oil impacts the cooling oil accumulated around the heating element. The hot oil rapidly diffuses from the surface of the heating element to the surrounding area. When the low-temperature cooling oil impacts the surface of the heating element, the high temperature difference between the cooling oil and the heating element accelerates heat absorption. The impacted cooling oil mixes with the heat-absorbed hot oil, rapidly cooling the hot oil around the heating element.

Description

Technical Field

[0001] This invention belongs to the field of self-heating transformer technology, specifically an automatic heat dissipation transformer. Background Technology

[0002] Intelligent large oil-immersed transformers improve the insulation performance of electrical components such as iron core windings by immersing them in transformer oil, optimize the heat transfer and heat dissipation performance of the electrical components, and also effectively protect the iron core and windings from the effects of moisture in the air. Transformers are devices that use the principle of electromagnetic induction to change AC voltage. During use, transformers have poor heat dissipation efficiency, which can easily affect their service life.

[0003] A patent with publication number CN116092788 discloses an oil-immersed transformer with automatic heat dissipation, belonging to the field of transformer technology. It includes an oil tank, with a first heat dissipation structure and a second heat dissipation structure disposed on the side wall of the tank. The first heat dissipation structure includes several first heat dissipation pipes parallel to each other distributed on the outer side of the oil tank, and the second heat dissipation structure includes several second heat dissipation pipes parallel to each other distributed on the outer side of the oil tank. One end of each first heat dissipation pipe is connected to the inner cavity of the oil tank, and the other end of each first heat dissipation pipe is connected in parallel to a main manifold. It also includes an oil drum, inside which a piston plate is slidably connected along the axis of the oil drum. The piston plate divides the oil drum into an oil inlet chamber and an oil return chamber. The oil inlet chamber is connected to a first main manifold, and the oil return chamber is connected to a second main manifold. A telescopic guide rod connecting the piston plate and the inner wall of the oil drum is disposed in the oil return chamber. This invention has the advantage of high heat dissipation efficiency.

[0004] Currently, all intelligent large transformers use oil-immersed cooling methods. However, the low-temperature cooling oil becomes a heat source after absorbing heat. Existing methods for cooling this hot oil involve either using the transformer's outer shell for blade heat dissipation or passing the oil through pipes and using a fan to blow air through one end of the pipes to cool the internal temperature. Since the cooling oil inside the intelligent large transformer is static due to the lack of external force, air cooling can only effectively cool the oil near the edge of the transformer's outer shell and around the pipes. The oil in more distant locations and around the heat-generating components cannot be effectively cooled and can only be cooled through heat exchange between the oil components. This cooling method is relatively slow and has low efficiency.

[0005] Therefore, the present invention provides an automatic heat dissipation transformer. Summary of the Invention

A condensing copper pipe is fixedly connected to the inner wall of the cooling box, and both ends of the condensing copper pipe extend through the cooling box to the outer surface.

[0009] Preferably, a concentrator is fixedly connected to the bottom surface of the cooling box and to the receiving end of the condensing copper pipe, a blower is fixedly connected to the inner wall of the concentrator, and an iron core winding is fixedly installed on the other end of the circulating oil pipe.

[0010] Preferably, a return pipe is fixedly connected to one edge of the top of the cooling box, a drain pipe is fixedly connected to the bottom surface of the cooling box, and a water pump is provided at the other end of the drain pipe.

[0011] Preferably, one end of the water pump and the return pipe extends to the inner wall of the intelligent large transformer, and two sets of heat absorption boxes are fixedly installed on one end of the return pipe and the output end of the water pump, respectively.

[0012] Preferably, the circulating oil pipe is located on the inner wall of the heat absorption box, one end of the circulating oil pipe is fixedly connected to the outer surface of the iron core winding, one end of the two circulating oil pipes passes through the transformer oil tank and extends to the inner wall of the upper oil chamber and the lower oil chamber respectively, and the iron core winding is located on the inner wall of the intelligent large transformer.

[0013] Preferably, both ends of the transmission rod are fixedly connected to the outer surface of the eccentric rotating disk, and limit groove rings are fixedly connected to the outer surface of the transmission rod at both edges. A sealing ring is fixedly installed on the inner wall of the transformer oil tank. The outer surface of the transmission compression rod is movably overlapped on the inner wall of the sealing ring. The outer surface of the lower pressure plate is movably sleeved on the inner wall of the transformer oil tank. The upper oil cavity and the lower oil cavity are respectively located at the upper and lower edges of the lower pressure plate.

[0014] Preferably, a support frame is fixedly connected to the outer surface of the transformer oil tank, a transmission rod is movably sleeved on the inner wall of the support frame, and a transmission track disposed on the outer surface of the limit groove ring is movably sleeved on the output end of the motor.

[0015] Preferably, the intelligent large transformer has heat dissipation grooves on its front and rear surfaces, high-voltage side bushings are fixedly installed on the top surface of the intelligent large transformer and at the two side edges, and a support base is fixedly installed on the bottom surface of the intelligent large transformer.

[0016] Preferably, a support block is fixedly connected to the outer surface of the second support frame, and the outer surface of the support block is fixedly connected to the outer surface of the air collecting box.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The automatic heat dissipation transformer of the present invention, when the lower pressure plate moves down, will pump the cooling oil inside the lower oil chamber into the interior of the iron core winding through the circulating oil pipe; at this time, the interior of the upper oil chamber will be in a semi-vacuum state, and another circulating oil pipe will draw the cooling oil into the interior of the upper oil chamber. When the lower pressure plate moves up, the cooling oil will flow back into the outer surface of the iron core winding in the opposite direction along the circulating oil pipe. The circulating oil pipe is used to circulate and guide the cooling oil back and forth, thereby achieving the effect of repeated flow of cooling oil.

[0019] 2. When the cooling oil enters the iron core winding, the impact of the cooling oil will impact the cooling oil accumulated around the heating element. Taking advantage of the higher fluidity of hot oil than cold oil, the hot oil will spread rapidly from the surface of the heating element to the surrounding area under the impact of the cold oil. The flowing cold oil will hit the surface of the heating element, and the higher temperature difference will allow the surface of the heating element to quickly absorb heat. The impacted cooling oil will mix with the heat-absorbing hot oil, which will have the effect of quickly cooling down the hot oil around the heating element.

[0020] 3. The automatic heat dissipation transformer of the present invention absorbs the hot oil inside the iron core winding through another circulating oil pipe when the pressure plate moves down. Utilizing the height difference between the two circulating oil pipes, the cooling oil that has previously entered the iron core winding can be absorbed each time the cooling oil is drawn. With the absorption and absorption of the cooling oil, the cooling oil on the surface of the iron core winding will be continuously stirred, which will disperse the hot oil around the heating element after absorbing the heat source, so that the area around the heating element is kept at a low temperature, thereby maintaining the effect of optimal absorption.

[0021] 4. The automatic heat dissipation transformer of the present invention, when the cooling oil circulates, is used in conjunction with a water pump to absorb low-temperature coolant inside the inlet pipe. The flowing low-temperature coolant fills the inside of the heat absorption box. Utilizing the thermal conductivity of the circulating oil pipe, the heat source inside the circulating oil pipe interacts with the low-temperature coolant outside. The low-temperature coolant inside the heat absorption box flows rapidly through the inlet and return pipes, so that the temperature inside the heat absorption box is kept at a low temperature.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 9 As shown, an automatic heat dissipation transformer according to an embodiment of the present invention includes an intelligent large transformer 11 and a detachable anti-collision shell 12 installed on both sides of the intelligent large transformer 11. Two sets of transformer oil tanks 121 are fixedly installed on the inner walls of the upper and lower sides of the anti-collision shell 12. A motor 125 is fixedly installed on the inner wall of the bottom of the anti-collision shell 12. A transmission compression rod a2 is movably sleeved on the inner wall of the transformer oil tank 121. Lower pressure plates a2 are fixedly installed at both ends of the transmission compression rod a2. 4. The inner wall of the transformer oil tank 121 is provided with an upper oil chamber a5 and a lower oil chamber a6 respectively. Two circulating oil pipes 139 are fixedly installed on the outer surface of the transformer oil tank 121. The interior of the transformer oil tank 121 is filled with low temperature cooling oil. A rectangular limiting strip a3 is fixedly installed on the outer surface of the transmission extrusion rod a2 at the middle position. A push rod 128 is movably sleeved on the inner wall of the rectangular limiting strip a3. An eccentric rotating disk 127 is fixedly connected to the outer surface of the push rod 128.

[0035] The motor 125 drives the eccentric rotating disk 127 to rotate. During this rotation, the eccentric rotating disk 127 drives the push rod 128 to rotate. As the outer surface of the push rod 128 slides on the inner wall of the rectangular limiting strip a3, it pushes the rectangular limiting strip a3, causing it to maintain a horizontal angle and move up and down along the surface of the eccentric rotating disk 127. As the push rod 128 moves inside the rectangular limiting strip a3, it drives the lower pressure plate a4 on the upper and lower surfaces of the rectangular limiting strip a3 to move up and down on the inner wall of the anti-collision sleeve 12. When the lower pressure plate a4 moves towards the lower oil chamber a6, it pumps the cooling oil inside the lower oil chamber a6 into the outer surface of the iron core winding 1311 through the circulating oil pipe 139. When the lower pressure plate a4 presses down, the upper oil chamber... The interior of a5 will be in a semi-vacuum state, and then the cooling oil will be drawn into the interior of the upper oil chamber a5 through another circulating oil pipe 139. When the pressure plate a4 begins to move upward, the cooling oil filled in the upper oil chamber a5 will flow back into the interior of the iron core winding 1311 in the opposite direction along the circulating oil pipe 139. When the cooling oil enters the interior of the iron core winding 1311, the impact of the cooling oil will impact the cooling oil accumulated around the heating element. Taking advantage of the higher fluidity of hot oil than that of low-temperature cooling oil, under the impact of the low-temperature cooling oil, the hot oil will spread rapidly from the surface of the heating element to the surrounding area. When the low-temperature cooling oil hits the surface of the heating element, the high temperature difference will allow the surface of the heating element to quickly absorb the heat source. The cooling oil after impact will mix with the hot oil after absorbing heat, which will have the effect of quickly cooling down the hot oil around the heating element.

[0036] The transformer oil tank 121 is used to circulate and cool the cooling oil, and the lower pressure plate a4 is used to squeeze and extract the cooling oil, causing the cooling oil to impact inside the iron core winding 1311 and agitate the static cooling oil, so that the hot oil can flow everywhere, and thus the hot oil and the low temperature cooling oil can be quickly mixed together. With the flow of the low temperature cooling oil, the area around the heating element can be kept at a low temperature. The coolant absorbs heat and cools the hot oil inside the circulating oil pipe 139, and at the same time, the fan is used to achieve the effect of rapid cooling of the coolant.

[0037] like Figures 1 to 9As shown, a support frame 122 is fixedly connected to the outer surface of the transformer oil tank 121. A transmission rod 123 is movably sleeved on the inner wall of the support frame 122. The two ends of the transmission rod 123 are fixedly connected to the outer surface of the eccentric rotating disk 127. A limit groove ring 124 is fixedly connected to the outer surface of the transmission rod 123 and located at the two side edges. A transmission track 126 is movably sleeved on the output end of the motor 125 and is provided on the outer surface of the limit groove ring 124. A sealing ring a1 is fixedly installed on the inner wall of the transformer oil tank 121. The outer surface of the transmission extrusion rod a2 is movably overlapped on the inner wall of the sealing ring a1.

[0038] When the cooling oil inside the lower oil chamber a6 enters the iron core winding 1311, the lower pressure plate a4 moves down and absorbs the hot oil inside the iron core winding 1311 through another circulating oil pipe 139. Utilizing the height difference between the two circulating oil pipes 139, the cooling oil that previously entered the iron core winding 1311 can be absorbed each time the cooling oil is drawn. As the hot oil flows into the upper oil chamber a5, the coolant will cool the hot oil. With the absorption and absorption of the cooling oil, the cooling oil inside the iron core winding 1311 will be continuously stirred, dispersing the hot oil that has absorbed the heat source around the heating element, keeping the area around the heating element at a low temperature, and ensuring that the heating element is always at a high temperature difference, maintaining the optimal absorption state.

[0039] like Figure 1 - Figure 2 and Figures 5 to 8 As shown, a return pipe 1310 is fixedly connected to one edge of the top of the cooling box 132, and a drain pipe 136 is fixedly connected to the bottom surface of the cooling box 132. A water pump 137 is installed at the other end of the drain pipe 136. One end of the water pump 137 and the return pipe 1310 extends to the inner wall of the intelligent large transformer 11. Two sets of heat absorption boxes 138 are fixedly installed at one end of the return pipe 1310 and the output end of the water pump 137, respectively. The position of the circulating oil pipe 139 is set on the inner wall of the heat absorption box 138. One end of the circulating oil pipe 139 is fixedly connected to the outer surface of the iron core winding 1311. One end of the two circulating oil pipes 139 passes through the transformer oil tank 121 and extends to the inner wall of the upper oil chamber a5 and the lower oil chamber a6, respectively. The position of the iron core winding 1311 is set on the inner wall of the intelligent large transformer 11.

[0040] When the cooling oil circulates, it works with the water pump 137 to absorb the low-temperature coolant inside the diversion pipe 136. The flowing low-temperature coolant fills the inside of the heat absorption box 138. Utilizing the thermal conductivity of the circulating oil pipe 139, the heat source inside the circulating oil pipe 139 interacts with the low-temperature coolant outside. The low-temperature coolant inside the heat absorption box 138 flows rapidly through the diversion pipe 136 and the return pipe 1310, so that the temperature inside the heat absorption box 138 is kept at a low temperature.

[0041] Since the surface of the circulating oil pipe 139 is always at a low temperature, and when the temperature difference between the inner wall of the circulating oil pipe 139 and the hot oil is large, rapid heat interaction will occur, so that the hot oil can be cooled down quickly when it flows, so that the cooling oil entering the iron core winding 1311 can always be kept at the optimal low temperature.

[0042] like Figures 1 to 2 and Figure 8 - Figure 9 As shown, transformer heat dissipation grooves 113 are provided on the front and rear sides of the intelligent large transformer 11. High-voltage side bushings 112 are fixedly installed on the top surface of the intelligent large transformer 11 and at the two side edges. Support base 111 is fixedly installed on the bottom surface of the intelligent large transformer 11. Support blocks are fixedly connected to the outer surface of the support frame 13. The outer surface of the support blocks is fixedly connected to the outer surface of the air collection box 134.

[0043] The transformer heat dissipation groove 113 on the outer surface of the intelligent large transformer 11 increases the contact area and range with the outside world. At the same time, the transformer heat dissipation groove 113 absorbs and transfers the heat source inside the intelligent large transformer 11. When the natural wind blows on the surface of the transformer heat dissipation groove 113, the wind will carry away the residual heat on the surface of the transformer heat dissipation groove 113, thereby dissipating the residual heat inside the intelligent large transformer 11 and cooling it down.

[0044] like Figures 1 to 4 and Figure 7 - Figure 9 As shown, a support frame 2 13 is fixedly installed on the back of the intelligent large transformer 11. An arc-shaped support seat 131 is fixedly installed on the top outer surface of the support frame 2 13. A cooling box 132 is detachably installed on the top outer surface of the arc-shaped support seat 131. A condensing copper pipe 133 is fixedly connected to the inner wall of the cooling box 132, and both ends of the condensing copper pipe 133 extend through the cooling box 132 to the outer surface. A concentrator box 134 is fixedly connected to the bottom surface of the cooling box 132 and to the receiving end of the condensing copper pipe 133. A blower 135 is fixedly connected to the inner wall of the concentrator box 134. An iron core winding 1311 is fixedly installed on the other end of the circulating oil pipe 139.

[0045] After absorbing the heat source, the coolant enters the cooling box 132 through the return pipe 1310. There, it works with the condensing copper pipe 133 inside the cooling box 132 to absorb the heat source within the coolant. Simultaneously, the blowers 135 inside the air collecting box 134 blow air. The air absorbed by multiple blowers 135 quickly accumulates inside the air collecting box 134. This accumulated air is then compressed, and the compressed air flows rapidly through the inner wall of the condensing copper pipe 133. This rapid flow of cold air carries away the heat source inside the condensing copper pipe 133, discharging the hot air. As the air flows rapidly out, the inner wall of the condensing copper pipe 133 remains in a state of thermal interaction, greatly accelerating the cooling speed of the coolant.

[0046] Working principle: When the pressure plate a4 moves towards the lower oil chamber a6, the cooling oil inside the lower oil chamber a6 will be pumped into the outer surface of the iron core winding 1311 through the circulating oil pipe 139. When the cooling oil enters the iron core winding 1311, the impact of the cooling oil will impact the cooling oil accumulated around the heating element. Taking advantage of the higher fluidity of hot oil than cold oil, under the impact of the cold oil, the hot oil will spread rapidly from the surface of the heating element to the surrounding area. When the cold oil hits the surface of the heating element, the high temperature difference will allow the surface of the heating element to quickly absorb the heat source. The cooling oil after impact will mix with the hot oil after absorbing heat, thus achieving the effect of rapid cooling of the hot oil around the heating element.

[0047] When the cooling oil inside the lower oil chamber a6 enters the iron core winding 1311, the lower pressure plate a4 moves down and absorbs the hot oil inside the iron core winding 1311 through another circulating oil pipe 139. Utilizing the height difference between the two circulating oil pipes 139, the cooling oil that previously entered the iron core winding 1311 can be absorbed each time the cooling oil is drawn. As the hot oil is guided into the upper oil chamber a5, the coolant will cool the hot oil. With the absorption and absorption of the cooling oil, the cooling oil inside the iron core winding 1311 will be continuously stirred, dispersing the hot oil that has absorbed the heat source around the heating element, so that the area around the heating element is kept at a low temperature, and the heating element can always be in a high temperature difference, maintaining the optimal absorption state.

[0048] When the cooling oil circulates, it works with the water pump 137 to absorb the low-temperature coolant inside the diversion pipe 136. The flowing low-temperature coolant fills the inside of the heat absorption box 138. Utilizing the thermal conductivity of the circulating oil pipe 139, the heat source inside the circulating oil pipe 139 interacts with the low-temperature coolant outside. The low-temperature coolant inside the heat absorption box 138 flows rapidly through the diversion pipe 136 and the return pipe 1310, so that the temperature inside the heat absorption box 138 is kept at a low temperature.

[0049] Since the surface of the circulating oil pipe 139 is always at a low temperature, and when the temperature difference between the inner wall of the circulating oil pipe 139 and the hot oil is large, rapid heat interaction will occur, so that the hot oil can be cooled down quickly when it flows, so that the cooling oil entering the iron core winding 1311 can always be kept at the optimal low temperature.

[0050] After absorbing the heat source, the coolant enters the cooling box 132 through the return pipe 1310. The shape of the condensing copper tube 133 inside the cooling box 132 increases the contact area and range with the coolant, thereby absorbing the heat source inside the coolant over a large area. At this time, the blowers 135 inside the air collecting box 134 blow air. The air absorbed by multiple blowers 135 will quickly accumulate inside the air collecting box 134. The air gradually accumulating inside the air collecting box 134 will be compressed. The compressed air will flow rapidly through the inner wall of the condensing copper tube 133. When the cold air flows rapidly, it will carry away the heat source inside the condensing copper tube 133 and discharge the hot air. As the gas flows rapidly and is discharged, the inner wall of the condensing copper tube 133 is always in a state of heat interaction, which greatly accelerates the cooling speed of the coolant.

[0051] The transformer oil tank 121 is used to circulate and cool the cooling oil, and the pressure plate a4 is used to squeeze and extract the cooling oil, causing the cooling oil to impact inside the iron core winding 1311. This agitates the static cooling oil, allowing the hot oil to flow freely and quickly mix with the low-temperature cooling oil. As the low-temperature cooling oil flows, the area around the heating element is kept at a low temperature. At the same time, the low-temperature coolant inside the cooling tank 132 cools the hot oil, and the coolant absorbs heat from the hot oil inside the circulating oil pipe 139 to cool it down. The fan also helps to quickly cool the coolant.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
