Description

Technical Field

[0001] This invention relates to the field of rectifier technology, and in particular to an integrated rectifier cooling structure. Background Technology

[0002] A rectifier is a device that converts alternating current (AC) into direct current (DC). It can be used in power supply devices and for detecting radio signals. Rectifiers can be made from vacuum tubes, ignition tubes, solid-state silicon semiconductor diodes, mercury arc diodes, etc. However, rectifiers generate a lot of heat during operation, so they need to be equipped with appropriate heat dissipation and cooling equipment.

[0003] Patent CN111462985B discloses a rapid heat dissipation oil-immersed rectifier. The accelerated heat dissipation mechanism can accelerate the flow of transformer oil inside the transformer shell, thereby accelerating the heat dissipation of the transformer oil. A temperature sensor is installed on the side wall of the transformer shell to sense the temperature of the transformer shell. When the temperature sensor senses that the temperature of the transformer shell is high, the temperature sensor transmits the sensing signal to the controller. Then the controller controls the accelerated heat dissipation mechanism to work, thereby accelerating the heat dissipation of the transformer oil.

[0004] However, the aforementioned existing technology has the following technical defects: First, the heat dissipation effect of this device on the rectifier is generally poor. Since the rectifier generates heat all around, the temperature of the transformer oil around the rectifier is also high. However, this device draws transformer oil from the bottom, cools it, and then discharges it above the oil body. In addition, there is a lot of transformer oil in the shell, which causes the transformer oil around the rectifier to circulate slowly. It is not possible to replace the oil around the rectifier in a short time, resulting in the problem of poor heat dissipation of the rectifier. Second, this device uses spray heads to spray water to cool the heat dissipation pipes. However, some of the spray water absorbs heat and vaporizes into water vapor. However, this device does not have a water vapor recovery structure. Moreover, other electrical appliances are usually installed around the rectifier installation location. This water vapor condenses on other electrical appliances, collects into large water droplets, and enters the interior of the electrical appliances, which can easily cause water damage and economic losses.

[0005] In summary, existing technologies still have room for improvement in terms of rectifier heat dissipation and water vapor recovery. Therefore, it is necessary to develop a device that can improve rectifier heat dissipation and recover water vapor. Summary of the Invention

[0006] To address the aforementioned issues, this application provides an integrated rectifier cooling structure, employing the following technical solution: It includes a cooling chamber, inside which is a movable mechanism. The movable mechanism comprises a rectangular cylinder, with a partition installed on the inner wall of the rectangular cylinder. Several evenly distributed cylindrical shells are embedded in the upper side of the partition, and several circularly distributed oil drain holes are opened on the sides of the cylindrical shells. A piston, adapted to the partition and sealing all the oil drain holes on the cylinder, is installed inside the cylinder. A vertical rod extending to the outside of the cooling chamber is installed at the lower center of the piston, and a connecting plate is installed at the lower end of all the vertical rods.

[0007] Each side of the rectangular tube is provided with a set of evenly distributed oil inlet holes. A plugging plate that is adapted to the rectangular tube and blocks all the oil inlet holes is slidably installed on the outside of the rectangular tube. Two first L-shaped plates that are fixedly connected to the connecting plate are symmetrically installed on the side of the plugging plate.

[0008] Preferably, the lower side of the cooling box has four rectangular rods that penetrate the connecting plate. The lower end of the rods is fitted with a limit plate, and a spring is fitted on the rod above the limit plate.

[0009] Preferably, a second L-shaped plate is installed on the lower side of the connecting plate, and a rack is installed on the side of the second L-shaped plate on one side of the cooling box.

[0010] Preferably, a power unit is provided on the front side of the cooling box. The power unit includes a U-shaped plate, and a half gear that meshes with a rack is rotatably mounted on the side of the U-shaped plate.

[0011] Preferably, it also includes an oil cooling mechanism, which includes two outer shells installed on both sides of the cooling chamber. Several evenly distributed condenser tubes are provided inside the outer shells. The lower ends of all the condenser tubes on the same side extend to the outside of the cooling chamber and are all connected to a drain pipe.

[0012] Preferably, a connecting pipe is installed between each pair of adjacent condenser tubes, and all connecting pipes on the same side connect the corresponding pair of condenser tubes into a curved pipe.

[0013] Preferably, a baffle is installed near the bottom inside the condenser tube, and a rotating plate adapted to it is rotatably installed on the upper side of the baffle. A set of water outlet holes are symmetrically opened on the upper side of both the baffle and the rotating plate. The two water outlet holes on the baffle are not aligned with the two water outlet holes on the upper rotating plate.

[0014] Preferably, a cylinder is installed at the center of the upper side of the rotating plate, and a movable rod that slides through the baffle and the rotating plate is provided inside the cylinder.

[0015] Preferably, the inner wall of the cylinder has two spiral grooves, and the side of the movable rod has two circular protrusions that are adapted to the spiral grooves symmetrically installed above the spiral grooves.

[0016] Preferably, all movable rods on the same side have a drain pipe running through their lower ends and a strip plate installed thereon. Two third L-shaped plates, which are fixedly connected to the connecting plate, are symmetrically installed on the lower side of the strip plate.

[0017] In summary, this application includes at least one of the following beneficial technical effects of integrated rectifier cooling structures:

[0018] I. This invention stores low-temperature transformer oil in the outer chamber of a rectangular cylinder within a cooling chamber. The transformer oil in the cooling chamber absorbs the heat generated by the rectifier. Simultaneously, with the cooperation of the moving mechanism and the power unit, the operation of rapidly discharging high-temperature transformer oil from the cooling chamber and rapidly entering low-temperature transformer oil is repeated. Due to the small volume of the cooling chamber and the fact that the transformer oil is all located around the rectifier, replacing the transformer oil in the cooling chamber is actually replacing the transformer oil around the rectifier. This allows for the rapid replacement of the high-temperature transformer oil around the rectifier, improving the heat dissipation and cooling effect on the rectifier.

[0019] II. With the cooperation of the movable mechanism and the oil cooling mechanism, the water vapor generated after the sprayed water exchanges heat with the high-temperature transformer oil will flow into the curved pipe composed of multiple condenser tubes and connecting pipes along with the air inside the shell. When passing through multiple condenser tubes, the water vapor can be completely condensed into water droplets and adhere to the inner wall of the condenser tubes. At the same time, the connecting plate in the movable mechanism repeatedly raises and lowers, driving all the movable rods to repeatedly raise and lower. While scraping the water droplets off the inner wall of the condenser tubes with scrapers, the lower port of the condenser tubes can also be repeatedly opened and closed to discharge the scraped water from the condenser tubes, thereby realizing the recovery of water vapor and preventing water vapor from condensing into water on other electrical appliances and causing damage to the appliances.

[0038] The following is in conjunction with the appendix Figure 1 - Figure 16 The embodiments of the present invention will be described in detail below.

[0039] This application discloses an integrated rectifier cooling structure. With the cooperation of the moving mechanism and the power unit, the operation of rapidly discharging high-temperature transformer oil from the cooling chamber and rapidly entering low-temperature transformer oil into the cooling chamber is repeated. Since the cooling chamber is small in volume and the transformer oil is located around the rectifier, replacing the transformer oil in the cooling chamber is actually replacing the transformer oil around the rectifier. This enables rapid replacement of the high-temperature transformer oil around the rectifier, thereby improving the heat dissipation and cooling effect of the rectifier.

[0040] It should be specifically noted that the rectifier mentioned in this application refers to an oil-immersed rectifier, which can be integrated into a transformer for rectification operations. The integrated rectifier cooling structure of this application can be installed as part of the transformer, with the oil-immersed rectifier housed within the cooling structure. A detailed description of the cooling structure is provided in the following embodiments.

[0041] Example 1: like Figure 1As shown, the integrated rectifier cooling structure disclosed in this invention includes a cooling box 1, a power unit 4 is provided on the front side of the cooling box 1, the cooling box 1 is used to hold transformer oil, and the power unit 4 is used to provide power for the operation of the device.

[0042] like Figure 2 and Figure 3 As shown, the power unit 4 includes a U-shaped plate 401. A half gear 406 is rotatably mounted on the side of the U-shaped plate 401. A motor 402 with its drive end fixedly connected to the half gear 406 is mounted on the other side of the U-shaped plate 401. A disc 403 with the same center as the half gear 406 is mounted on the side of the half gear 406. The motor 402 drives the half gear 406 to rotate, and the rotating half gear 406 drives the disc 403 to rotate.

[0043] like Figure 4 and Figure 5 As shown, the cooling box 1 is equipped with a movable mechanism 2 inside. The movable mechanism 2 includes a rectangular tube 201. A partition 202 is installed on the inner wall of the rectangular tube 201. The rectangular tube 201 divides the interior of the cooling box 1 into two chambers, an inner chamber and an outer chamber. The partition 202 divides the interior of the rectangular tube 201 from top to bottom into a cooling chamber and a transfer chamber.

[0044] like Figure 6 and Figure 7 As shown, several uniformly distributed cylindrical shells 203 are embedded in the upper side of the partition 202. Several circularly distributed oil drain holes 204 are opened on the side of the cylindrical shells 203. A piston 205 is provided inside the cylinder of the partition 202, which is adapted to it and blocks all the oil drain holes 204 on the cylinder. When all the pistons 205 descend and move out of the cylindrical shells 203, the blockage of the oil drain holes 204 is released, and the transformer oil in the cooling chamber leaks into the transfer chamber from the oil drain holes 204.

[0045] like Figure 6 , Figure 8 and Figure 9 As shown, a vertical rod 206 extending to the outside of the cooling box 1 is installed at the lower center of the piston 205. A connecting plate 207 is installed at the lower end of all the vertical rods 206. A second L-shaped plate 216 is installed on the lower side of the connecting plate 207. A rack 217 that meshes with the half gear 406 is installed on the side of the second L-shaped plate 216 on one side of the cooling box 1. The rotating half gear 406 drives the rack 217 to descend. The descending rack 217 drives the connecting plate 207 to descend through the second L-shaped plate 216. The descending connecting plate 207 drives the piston 205 to descend through each vertical rod 206. like Figure 1As shown, a set of second slide bars 8 are installed on the front side of the cooling box 1 on one side of the rack 217. The side of the rack 217 is equipped with a second slider 9 that slides on the two second slide bars 8. The moving rack 217 drives the second slider 9 to slide on the second slide bars 8, thereby enhancing the stability of the rack 217 when it moves.

[0046] like Figure 5 and Figure 6 As shown, each side of the rectangular cylinder 201 is provided with a set of evenly distributed oil inlet holes 208. A blocking plate 209 adapted to the rectangular cylinder 201 and blocking all the oil inlet holes 208 is slidably arranged on the outer side of the rectangular cylinder 201. Two first L-shaped plates 210 fixedly connected to the connecting plate 207 are symmetrically installed on the side of the blocking plate 209. When the connecting plate 207 descends, the blocking plate 209 is driven to descend through the two first L-shaped plates 210. The descending blocking plate 209 releases the blockage of all the oil inlet holes 208. The transformer oil in the cooling box 1 that is outside the rectangular cylinder 201 enters the cooling chamber through the oil inlet holes 208.

[0047] like Figure 5 As shown, the rectangular tube 201 has four first slide rods 6 mounted on its side. The first slide rods 6 are slidably mounted with first sliders 7 that are fixedly connected to the blocking plate 209. The moving blocking plate 209 drives the first sliders 7 to slide on the first slide rods 6, thereby enhancing the stability of the blocking plate 209 when it moves.

[0048] like Figure 5 As shown, four rectangular rods 211 are installed on the lower side of the cooling box 1, passing through the connecting plate 207. A limit plate 212 is installed at the lower end of the rods 211. Springs 213 are sleeved on the rods 211 above the limit plate 212. When the descending connecting plate 207 compresses the four springs 213, the half gear 406 rotates half a turn and does not mesh with the rack 217. All the compressed springs 213 rebound and drive the pistons 205 and the blocking plate 209 to return to their original positions, thus re-sealing the oil drain hole 204 and the oil inlet hole 208.

[0049] like Figure 2 and Figure 6 As shown, a drive plate 404 is rotatably mounted on the side edge of the disc 403, and a fixed plate 405 is rotatably mounted on the lower end of the drive plate 404. A pressure plate 214 is slidably disposed inside the rectangular cylinder 201 below the partition plate 202. A connecting rod 215 is installed at the lower center of the pressure plate 214, extending to the outside of the cooling box 1 and fixedly connected to the fixed plate 405. The rotating disc 403 drives the fixed plate 405 to move up and down through the drive plate 404. When the fixed plate 405 descends, it drives the pressure plate 214 to descend through the connecting rod 215. When the fixed plate 405 rises, it drives the pressure plate 214 to rise through the connecting rod 215 to squeeze out the transformer oil in the transfer chamber.

[0050] In summary, the running motor 402 drives the half gear 406 to rotate, the rotating half gear 406 drives the disk 403 to rotate, the rotating disk 403 drives the plate 404 to lower the fixed plate 405, and through the connecting rod 215 drives the pressure plate 214 to lower. At the same time, the rotating half gear 406 drives the rack 217 to lower, and the lowering rack 217 drives the connecting plate 207 to lower through the second L-shaped plate 216, compressing the four springs 213. The lowering connecting plate 207 drives the pistons 205 to lower through each vertical rod 206. When all the pistons 205 have lowered and moved out of the cylindrical shell 203, the blockage of the oil drain hole 204 is released. The high-temperature transformer oil that absorbs the heat generated by the rectifier in the cooling chamber leaks from the oil drain hole 204 into the transfer chamber. At the same time, when the connecting plate 207 lowers, it drives the two first L-shaped plates 210 to lower. The blocking plate 209 descends, releasing the blockage of all oil inlets 208. Low-temperature transformer oil outside the rectangular cylinder 201 in the cooling chamber 1 enters the cooling cavity through the oil inlets 208, continuing to cool the rectifier. After the half gear 406 and the disc 403 rotate half a turn, the half gear 406 no longer meshes with the rack 217. All the compressed springs 213 rebound, causing the pistons 205 and the blocking plate 209 to return to their original positions, re-blocking the drain hole 204 and the oil inlet 208. The rotating disc 403 causes the fixed plate 405 to rise, which in turn causes the pressure plate 214 to rise, squeezing out the high-temperature transformer oil in the intermediate chamber. The continuously rotating half gear 406 rotates half a turn and re-meets with the rack 217, repeating the above operation to continuously replace the transformer oil in the cooling cavity.

[0051] like Figure 4 , Figure 10 and Figure 11 As shown, it also includes an oil cooling mechanism 3. The oil cooling mechanism 3 also includes two outer shells 301 installed on both sides of the cooling box 1. A set of heat dissipation pipes 313 are symmetrically arranged inside the outer shells 301. One end of the heat dissipation pipe 313 is connected to the rectangular cylinder 201 and the connection is close to the partition 202. The other end of the heat dissipation pipe 313 is connected to the cooling box 1 and the connection is close to the bottom. The transformer oil squeezed out of the transfer chamber enters the heat dissipation pipe 313. After being cooled by the oil cooling mechanism 3, it becomes low-temperature transformer oil and returns to the cooling box 1.

[0052] like Figure 10 and Figure 11As shown, a T-shaped pipe 315 is installed above each heat dissipation pipe 313 inside the outer casing 301. The input ends of the two T-shaped pipes 315 on the same side are connected to a drain pipe 316. A set of fans 319 are installed on both sides of the outer casing 301. The other ends of the two drain pipes 316 are connected to the external water supply. The fans 319 blow air onto the heat dissipation pipes 313 to increase the air circulation around the heat dissipation pipes 313 and dissipate the transformer oil flowing through the heat dissipation pipes 313. Water is injected into the two drain pipes 316 and sprayed onto the heat dissipation pipes 313 through each T-shaped pipe 315. The spray water enhances the heat dissipation of the transformer oil in the heat dissipation pipes 313.

[0053] like Figure 10 and Figure 11 As shown, the outer casing 301 is provided with several evenly distributed condenser tubes 302. The rightmost end of the condenser tube 302 of the outer casing 301 is provided with several evenly distributed air inlets 320. A connecting pipe 304 is installed between each pair of adjacent condenser tubes 302. All connecting pipes 304 on the same side connect the corresponding pair of condenser tubes 302 into a curved pipe. Some of the sprayed water absorbs the heat of the transformer oil and turns into water vapor, which then enters the condenser tube 302 through the air inlets 320. The air and water vapor entering the condenser tube 302 flow in the curved pipe formed by the multiple condenser tubes 302 and the connecting pipes 304.

[0054] like Figure 10 and Figure 11 As shown, the upper end of the leftmost condenser tube 302 inside the outer casing 301 extends to the outside of the outer casing 301. Several evenly distributed first heat sinks 303 are installed on the side of the condenser tube 302. When the fan 319 blows air into the outer casing 301, it can also accelerate the air circulation around the condenser tube 302. At the same time, it works with the first heat sinks 303 to cool down the water vapor, allowing the water vapor to condense inside the condenser tube 302. After passing through multiple condenser tubes 302, the water vapor can be completely condensed into water droplets that adhere to the inner wall of the condenser tube 302. Meanwhile, air is discharged from the upper end of the leftmost condenser tube 302.

[0055] like Figure 11 and Figure 12 As shown, a baffle 306 is installed near the bottom inside the condenser tube 302. A rotating plate 307 is rotatably installed on the upper side of the baffle 306. A set of water outlet holes 308 are symmetrically opened on the upper side of both the baffle 306 and the rotating plate 307. The two water outlet holes 308 on the baffle 306 are not aligned with the two water outlet holes 308 on the upper rotating plate 307. When the two water outlet holes 308 on the baffle 306 are not aligned with the two water outlet holes 308 on the upper rotating plate 307, the lower end of the condenser tube 302 can be sealed.

[0056] like Figure 12 , Figure 13 and Figure 14As shown, a cylinder 309 is installed at the center of the upper side of the rotating plate 307. A movable rod 305 is slidably arranged inside the cylinder 309, passing through the baffle 306 and the rotating plate 307. The lower ends of all movable rods 305 on the same side pass through the drain pipe 316 and are installed with strip plates 317. Two third L-shaped plates 318, which are fixedly connected to the connecting plate 207, are symmetrically installed on the lower side of the strip plates 317. When the connecting plate 207 descends, it drives all movable rods 305 to descend through the third L-shaped plates 318 and the strip plates 317. When the connecting plate 207 rises, it also drives all movable rods 305 to rise.

[0057] like Figure 12 and Figure 13 As shown, the inner wall of the cylinder 309 has two spiral grooves 310. The side of the movable rod 305 is symmetrically equipped with two circular protrusions 311 that are adapted to the spiral grooves 310. When the movable rod 305 descends, it will also drive the two circular protrusions 311 to descend. When the two circular protrusions 311 enter the two spiral grooves 310, the descending circular protrusions 311 cooperate with the spiral grooves 310 to make the cylinder 309 and the rotating plate 307 rotate. When the movable rod 305 is lowered to the lowest point, the two water outlets 308 on the rotating plate 307 are aligned with the two water outlets 308 on the baffle 306, opening the lower end of the condenser tube 302. When the movable rod 305 rises, it will also drive the circular protrusions 311 to rise. Through the spiral grooves 310, the rotating plate 307 will reverse, causing the two sets of water outlets 308 to become misaligned, thus partially resealing the lower end of the condenser tube 302.

[0058] like Figure 11 and Figure 15 As shown, several evenly distributed scrapers 312 are installed on the side of the movable rod 305. The lower ends of all the condenser tubes 302 on the same side extend to the outside of the cooling box 1 and are connected to a drain pipe 316. The drain pipe 316 is connected to the outer shell 301 above. Water sprayed on the heat dissipation tubes 313 inside the outer shell 301 enters the drain pipe 316 and is discharged. When the movable rod 305 descends, it also drives the scrapers 312 to descend. The descending scrapers 312 scrape off the water droplets adhering to the inner wall of the condenser tubes 302 and make them fall into the bottom of the condenser tubes 302. When the lower end of the condenser tubes 302 is opened, water enters the drain pipe 316 and is discharged.

[0059] In summary, the transformer oil squeezed out of the transfer chamber enters the heat dissipation pipe 313. The fan 319 blows air onto the heat dissipation pipe 313, increasing the air circulation around the heat dissipation pipe 313 and cooling the transformer oil flowing through it. Water is injected into the two drain pipes 316 and sprayed onto the heat dissipation pipe 313 through each tee pipe 315. The spray water enhances the cooling of the transformer oil in the heat dissipation pipe 313, turning it into low-temperature transformer oil that returns to the cooling box 1. The water sprayed onto the heat dissipation pipe 313 inside the outer shell 301 enters the drain pipe 316 and is discharged.

[0060] After some of the sprayed water absorbs the heat from the transformer oil and turns into water vapor, it enters the condenser tube 302 through the air inlet 320. The air and water vapor entering the condenser tube 302 flow in the curved pipe formed by multiple condenser tubes 302 and connecting pipe 304. After passing through multiple condenser tubes 302, the water vapor can be completely condensed into water droplets and adhere to the inner wall of the condenser tube 302. At the same time, the air is discharged from the top of the leftmost condenser tube 302.

[0061] When the connecting plate 207 descends, it drives all the movable rods 305 to descend via the third L-shaped plate 318 and the strip plate 317. When the connecting plate 207 rises, it also drives all the movable rods 305 to rise. When the movable rods 305 descend, they also drive the scraper 312 to descend. The descending scraper 312 scrapes off the water droplets adhering to the inner wall of the condenser tube 302, causing them to fall to the bottom of the condenser tube 302. The descending movable rods 305 also drive the two circular protrusions 311 on them to descend. When the two circular protrusions 311 enter the two spiral grooves 310, the descending circular protrusions 311 cooperate with the spiral grooves 310. 10. Rotate the cylinder 309 and the rotating plate 307. When the movable rod 305 is lowered to its lowest point, the two water outlets 308 on the rotating plate 307 are aligned with the two water outlets 308 on the baffle 306, opening the lower end of the condenser tube 302. The water at the bottom of the condenser tube 302 enters the drain pipe 316 and is discharged, thus cleaning the condensate in the condenser tube 302. When the movable rod 305 rises, it also drives the circular protrusion 311 to rise. Through the spiral groove 310, it drives the rotating plate 307 to reverse, causing the two sets of water outlets 308 to become misaligned, thus partially resealing the lower end of the condenser tube 302.

[0062] Example 2: Based on Example 1, as follows Figure 1 and Figure 16 As shown, the cooling box 1 is also equipped with a secondary heat dissipation unit 5, which includes a metal plate 501. Two mounting cylinders 502 are symmetrically installed on the upper side of the cooling box 1. Graphene rods 503 extending into the rectangular cylinder 201 are slidably installed inside the mounting cylinders 502. Several evenly distributed second heat dissipation fins 507 are installed on the upper side of the metal plate 501. The transformer oil in the cooling chamber can transfer heat to each of the second heat dissipation fins 507 through the graphene rods 503, and then dissipate it into the surrounding air through the second heat dissipation fins 507, thereby enhancing the heat dissipation of the rectifier. At the same time, it can continue to dissipate heat for the rectifier when the oil body heat dissipation mechanism 3 stops working.

[0063] like Figure 1 and Figure 16As shown, the graphene rod 503 has several evenly distributed adjustment holes 504 on its side. The mounting cylinder 502 has a through hole 505 aligned with one of the adjustment holes 504 on its side. A pin 506 is provided between the through hole 505 and the aligned adjustment hole 504, allowing different adjustment holes 504 on the graphene rod 503 to align with the through hole 505, thereby changing the length of the graphene rod 503 extending into the cooling cavity. This allows the lower end of the graphene rod 503 to be closer to the rectifier according to the rectifier's volume, enhancing the heat dissipation effect.

[0064] Working principle of the invention: S1. Rectifier installation: Install the integrated rectifier in the cooling chamber. Specifically, open the top cover of the cooling box 1 and install the integrated rectifier in the cooling chamber inside the rectangular cylinder 201. Then, inject transformer oil into the cooling box 1, which is located in the outer chamber of the rectangular cylinder 201 and the cooling chamber, so that the transformer oil overflows the rectifier. The transformer oil can absorb the heat generated by the rectifier during operation and cool it down.

[0065] S2. Transformer oil replacement: The high-temperature transformer oil in the cooling chamber is drained and replaced with low-temperature transformer oil. Specifically, the motor 402 drives the half gear 406 to rotate. The rotating half gear 406 drives the disc 403 to rotate. The rotating disc 403 drives the plate 404 to lower the fixed plate 405. Through the connecting rod 215, the pressure plate 214 is lowered. At the same time, the rotating half gear 406 drives the rack 217 to lower. The lowering rack 217 drives the connecting plate 207 to lower through the second L-shaped plate 216, compressing the four springs 213. Simultaneously, through each vertical rod... 206 drives piston 205 to descend. When all pistons 205 descend and move out of the cylindrical shell 203, the blockage of the oil drain hole 204 is released. The high-temperature transformer oil in the cooling chamber that absorbs the heat generated by the rectifier leaks from the oil drain hole 204 into the transfer chamber. At the same time, when the connecting plate 207 descends, it drives the blocking plate 209 to descend through the two first L-shaped plates 210. The descending blocking plate 209 releases the blockage of all oil inlets 208. The low-temperature transformer oil in the cooling box 1 that is outside the rectangular cylinder 201 enters the cooling chamber from the oil inlet 208 to continue cooling the rectifier.

[0066] S3, oil transfer: The high-temperature transformer oil in the transfer chamber is sent into the oil cooling mechanism 3. Specifically, after the half gear 406 and the disc 403 rotate half a turn, the half gear 406 does not mesh with the rack 217. All the compressed springs 213 rebound and drive the pistons 205 and the blocking plate 209 to return to their original positions, re-blocking the oil drain hole 204 and the oil inlet hole 208. The rotating disc 403 drives the fixed plate 405 to rise, which in turn drives the pressure plate 214 to rise and squeeze the high-temperature transformer oil in the transfer chamber into the cooling pipe 313. The half gear 406 continues to rotate half a turn and then re-meets with the rack 217. The operations of S2 and S3 are repeated to achieve continuous replacement of the transformer oil in the cooling chamber.

[0067] S4. Oil cooling: The high-temperature transformer oil flowing through the heat dissipation pipe 313 is cooled using the oil cooling mechanism 3. Specifically, the transformer oil is squeezed out of the transfer chamber and enters the heat dissipation pipe 313. The fan 319 blows air into the heat dissipation pipe 313 to increase the air circulation around the heat dissipation pipe 313 and dissipate the transformer oil flowing through the heat dissipation pipe 313. Water is injected into the two drain pipes 316 and sprayed onto the heat dissipation pipe 313 through each tee pipe 315. The spray water enhances the heat dissipation of the transformer oil in the heat dissipation pipe 313, turning it into low-temperature transformer oil that returns to the cooling box 1. The water sprayed onto the heat dissipation pipe 313 inside the outer shell 301 enters the drain pipe 316 and is discharged.

[0068] S5. Water vapor treatment: The water vapor generated in the oil body heat dissipation mechanism 3 is recovered. Specifically, some of the spray water absorbs the heat of the transformer oil and turns into water vapor, which then enters the condenser tube 302 through the air inlet 320. The air and water vapor entering the condenser tube 302 flow in the curved pipe formed by multiple condenser tubes 302 and connecting pipe 304. When the fan 319 blows air into the outer casing 301, it can also accelerate the air circulation around the condenser tube 302. At the same time, it works with the first heat sink 303 to cool the water vapor. After passing through multiple condenser tubes 302, the water vapor can be completely condensed into water droplets and adhere to the inner wall of the condenser tube 302. Meanwhile, the air is discharged from the upper end of the leftmost condenser tube 302.

[0069] S6. Condensate Discharge: The condensate in each condenser tube 302 is discharged. Specifically, when the connecting plate 207 descends, it drives all the movable rods 305 to descend via the third L-shaped plate 318 and the strip plate 317. When the connecting plate 207 rises, it also drives all the movable rods 305 to rise. When the movable rods 305 descend, they also drive the scraper 312 to descend. The descending scraper 312 scrapes off the water droplets adhering to the inner wall of the condenser tube 302, causing them to fall to the bottom of the condenser tube 302. The descending movable rods 305 also drive the two circular protrusions 311 on them to descend. When the two circular protrusions 311 enter the two spiral grooves 310, the descending circular protrusions 311 cooperate with the spiral grooves 310. 10. Rotate the cylinder 309 and the rotating plate 307. When the movable rod 305 is lowered to its lowest position, the two water outlets 308 on the rotating plate 307 are aligned with the two water outlets 308 on the baffle 306, opening the lower end of the condenser tube 302. The water at the bottom of the condenser tube 302 enters the drain pipe 316 and is discharged. When the movable rod 305 rises, it also drives the circular protrusion 311 to rise. Through the spiral groove 310, it drives the rotating plate 307 to reverse, causing the two sets of water outlets 308 to misalign and partially re-closing the lower end of the condenser tube 302. As the connecting plate 207 moves up and down repeatedly, the lower end of the condenser tube 302 also opens and closes repeatedly, continuously discharging the condensate inside.
