Radiator fin connecting structure and radiator

Abstract

The application discloses a radiator fin connecting structure and a radiator, and relates to the technical field of radiators, in particular to a radiator fin connecting structure and a radiator.

Description

Technical Field

[0001] This invention relates to the field of radiator fin connection technology, specifically to a radiator fin connection structure and a radiator. Background Technology

[0002] Transformers generate heat during operation, specifically the heat generated by the load current flowing through the transformer windings. This heat must be dissipated in a timely manner. The component that dissipates this heat is the transformer radiator. Existing transformer radiators consist of two oil pipes and several heat dissipation fins connected between the two oil pipes. The heat dissipation fins have flow channels connecting the upper and lower oil pipes. During use, transformer oil enters through one oil pipe, flows through the flow channels and then through the heat dissipation fins to dissipate heat. Finally, the cooled transformer oil flows back to the transformer through the other oil pipe.

[0003] For example, Chinese patent CN105047366B discloses a transformer radiator with external fins fixedly connected and internal fins detachably connected. It includes two oil pipes and several heat dissipation fins connected between the two oil pipes. The heat dissipation fins have a flow channel connecting the two oil pipes. The heat dissipation fins have several external fins on their exterior. The external fins are integrally connected with the heat dissipation fins. The flow channel has internal fins and internal slots. The internal fins have internal fin part clips.

[0004] However, the above solution has the following shortcomings: According to the heat dissipation requirements of the radiator, a certain number of inner fins can be installed in the heat dissipation channel. The transformer oil entering the channel can be cooled by the set of several sets of inner fins. However, during use, a small amount of transformer oil will adhere to the surface of the inner fins after passing through them. The transformer oil adhering to the surface of the inner fins will affect the heat dissipation effect of the inner fins, resulting in poor overall heat dissipation effect of the radiator. If the installed inner fins are removed manually and the oil stains are cleaned, it will be time-consuming and laborious. Therefore, we have introduced a radiator fin connection structure and radiator. Summary of the Invention

[0005] The purpose of this invention is to provide a radiator fin connection structure and a radiator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A radiator fin connection structure includes a fin connection box, in which several sets of radiator fins are movably installed. A box cover is movably installed on the upper end of the fin connection box. Both the box cover and the lower end of the fin connection box have connection holes. A connecting ring is sleeved on the outer side of the radiator fin. A T-shaped plate is movably connected to the side of the connecting ring near the radiator fin. Two sets of T-shaped sliders are movably connected to the end of the T-shaped plate near the radiator fin. The T-shaped sliders slide in a guide groove, which is opened inside the connecting radiator fin. An oil storage cavity is provided on the lower side of the T-shaped plate, and the oil storage cavity is opened inside the connecting ring. A through hole is provided on one side of the connecting ring, which is connected to the oil storage chamber. A plug is movably engaged in the through hole. A positioning hole is provided at the lower end of the connecting ring, and a positioning rod is engaged in the positioning hole. The positioning rod is fixedly connected to the upper end of the connecting rod. A micro motor is fixedly connected to both ends of the connecting rod. A gear is fixedly connected to the output end of the micro motor. The gear meshes with a T-shaped tooth groove, which is located inside the fin connecting box.

[0007] Preferably, the heat dissipation fins are arranged in an I-shape, with both ends of the heat dissipation fins being snapped into T-shaped slots. The T-shaped slots are opened inside the connecting post, and the connecting post is fixedly connected to the fin connecting box. Several sets of outer fins are fixedly connected to the side of the connecting post away from the heat dissipation fins, and the ends of the outer fins away from the connecting post extend out of the fin connecting box.

[0008] Preferably, the T-shaped plate slides within a first T-shaped groove, which is located within a connecting ring. Two sets of first springs are fixedly connected within the first T-shaped groove, with the other end of each spring fixedly connected to the T-shaped plate. The T-shaped slider slides within a second T-shaped groove, which is located within the T-shaped plate. A second spring is fixedly connected within the second T-shaped groove, with the other end of each spring fixedly connected to the lower end of the T-shaped slider.

[0009] Preferably, a T-shaped rod is fixedly connected to the side of the plug near the oil storage cavity. The T-shaped rod slides in the limiting cavity, which is located inside the connecting ring. A limiting spring is sleeved on the outside of the T-shaped rod. One end of the limiting spring is fixedly connected to the limiting cavity, and the other end is fixedly connected to the T-shaped rod.

[0010] Preferably, an oil storage tank is fixedly connected to one side of the fin connecting box, an oil guide pipe is snapped into the through hole, several sets of oil guide holes are opened on the outside of the oil guide pipe, the end of the oil guide pipe away from the connecting ring extends into the oil storage tank, and an oil drain tap is fixedly connected to the end of the oil storage tank away from the fin connecting box.

[0011] Preferably, a push switch is provided on both sides of the connecting rod, the push switch is fixedly installed in the fin connecting box, and the lower end of the oil storage chamber is inclined.

[0013] In addition, to achieve the above objectives, the present invention also provides a radiator including the radiator fin connection structure described above.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by inserting both ends of the heat dissipation fins into the corresponding T-shaped slots, the heat dissipation fins and the fin connecting box can be connected together. The rotation of the micro motor causes the connecting ring to move along the surface of the heat dissipation fins. The cooperation between the T-shaped slider and the guide groove ensures that the T-shaped plate will not contact the surface of the heat dissipation fins when it moves to the left, but will contact the surface of the heat dissipation fins when it moves to the right. This achieves the cleaning of oil stains on the surface of the heat dissipation fins, and the cleaned oil stains are stored and collected, improving the overall heat dissipation effect of the radiator.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-8 The present invention provides a technical solution: Example

[0019] A radiator fin connection structure includes a fin connection box 1, within which several sets of heat dissipation fins 9 are movably installed. Depending on the heat dissipation requirements of the radiator, a corresponding number of heat dissipation fins 9 can be installed within the fin connection box 1. A cover 8 is movably installed at the upper end of the fin connection box 1. Both the cover 8 and the lower end of the fin connection box 1 have connection holes 6, allowing connection to oil pipes. A connecting ring 4 is sleeved on the outer side of each heat dissipation fin 9. A T-shaped plate 32 is movably connected to the side of the connecting ring 4 closest to the heat dissipation fin 9. The T-shaped plate 32 does not contact the surface of the heat dissipation fin 9 when it moves to the left. When the T-shaped plate 32 moves to the right, it will contact the surface of the heat dissipation fins 9, so that the oil stains on the surface of the heat dissipation fins 9 can be cleaned through one side of the T-shaped plate 32. This prevents the oil stains on the other side of the T-shaped plate 32 from re-adhering to the heat dissipation fins 9 when cleaning both sides of the T-shaped plate 32 due to the back and forth movement of the T-shaped plate 32. Two sets of T-shaped sliders 29 are movably connected in the end of the T-shaped plate 32 near the heat dissipation fins 9. The T-shaped plate 32 slides in the first T-shaped groove 20. The first T-shaped groove 20 is opened in the connecting ring 4. Two sets of first springs 34 are fixedly connected in the first T-shaped groove 20. The other end of the first spring 34 is fixedly connected to the T-shaped plate 32. T-shaped slider 29 slides within the second T-shaped groove 31, which is located within the T-shaped plate 32. A second spring 30 is fixedly connected within the second T-shaped groove 31, with its other end fixedly connected to the lower end of the T-shaped slider 29. Since the two sets of T-shaped sliders 29 within the T-shaped plate 32 slide within the guide groove 12, and since the lower groove of the guide groove 12 is deeper than the upper groove, when the two sets of T-shaped sliders 29 move along the upper groove, the T-shaped plate 32 is pushed outwards, compressing the first spring 34, causing the T-shaped plate 32 to... 2. It will not contact the heat dissipation fins 9. When the T-shaped slider 29 moves to the left side of the guide groove 12, the T-shaped slider 29 will be squeezed downward by the arc bend as the connecting ring 4 moves continuously. The T-shaped slider 29 moves downward along the second T-shaped groove 31 and compresses the second spring 30. When the T-shaped slider 29 is squeezed to the lower side of the guide groove 12, the depth of the lower side is greater than the depth of the upper groove. At this time, under the elastic force of the first spring 34, the T-shaped plate 32 will contact the heat dissipation fins 9. T-shaped slider 29 slides into guide groove 12, which is opened in the connecting heat dissipation fins 9. The depth of the lower groove of guide groove 12 is greater than the depth of the upper groove. There is an arc bend on the left side of guide groove 12. As the connecting ring 4 moves continuously, T-shaped slider 29 will be squeezed downward by the arc bend. T-shaped slider 29 moves downward along the second T-shaped groove 31 and compresses the second spring 30. There is a ramp on the right side of guide groove 12. When the connecting rod 18 drives the connecting ring 4 to move to the rightmost side and contact the right-side push switch 7, the two sets of micro motors 33 stop. At the same time, due to the ramp on the right side of guide groove 12, under the elastic force of the second spring 30, T-shaped slider 29 re-enters the upper groove of guide groove 12 along the ramp. At this time, T-shaped plate 32 will be squeezed away from heat dissipation fins 9 again. There is an oil storage cavity 21 on the lower side of T-shaped plate 32, which is opened in the connecting ring 4. A through hole 11 is provided on one side of the connecting ring 4, which is connected to the oil storage chamber 21. A plug 25 is movably engaged in the through hole 11. A positioning hole 17 is provided at the lower end of the connecting ring 4, and a positioning rod 22 is engaged in the positioning hole 17. The positioning rod 22 is fixedly connected to the upper end of the connecting rod 18. Micro motors 33 are fixedly connected to both ends of the connecting rod 18. The specific model of the micro motor 33 is HRF-370CA produced by Shenzhen Huajuntong Motor Co., Ltd. A gear 15 is fixedly connected to the output end of the micro motor 33. The gear 15 meshes with the T-shaped tooth groove 16. The T-shaped tooth groove 16 is opened in the fin connecting box 1. When the two sets of micro motors 33 are turned on, the micro motors 33 rotate and drive the gears 15 connected to their output ends to start rotating. Since the gears 15 mesh with the T-shaped tooth groove 16, the connecting rod 18 moves to the left under the drive of the two sets of gears 15. Example

[0020] Based on Embodiment 1, to facilitate the installation of the heat dissipation fins 9 and ensure that the plug 25 can be re-engaged into the through hole 11 when the oil guide pipe 23 leaves the through hole 11, the heat dissipation fins 9 are arranged in an I-shape. Both ends of the heat dissipation fins 9 are engaged in T-shaped slots 14. The T-shaped slots 14 are opened in the connecting post 13. The connecting post 13 is fixedly connected to the fin connecting box 1. Several sets of outer fins 10 are fixedly connected to the side of the connecting post 13 away from the heat dissipation fins 9. The end of the outer fin 10 away from the connecting post 13 extends out of the fin. Connect box 1, insert both ends of several sets of heat dissipation fins 9 into the corresponding T-shaped slots 14, and ensure that the positioning holes 17 at the lower end of the heat dissipation fins 9 are engaged with the positioning rods 22 during the insertion process. Install the box cover 8 onto the upper end of the fin connecting box 1 using several sets of screws 19. During the installation process, ensure that the limiting block 5 can be engaged into the T-shaped slots 14. The limiting block 5 can limit and fix the heat dissipation fins 9 to prevent them from shaking. At this point, the installation of several sets of heat dissipation fins 9 is completed. T-shaped plate 32 slides within the first T-shaped groove 20, which is located within the connecting ring 4. Two sets of first springs 34 are fixedly connected within the first T-shaped groove 20, with the other end of each spring fixedly connected to the T-shaped plate 32. T-shaped slider 29 slides within the second T-shaped groove 31, which is located within the T-shaped plate 32. A second spring 30 is fixedly connected within the second T-shaped groove 31, with the other end of each spring fixedly connected to the lower end of the T-shaped slider 29. A T-shaped rod 26 is fixedly connected to the plug 25 near the oil storage cavity 21, and the T-shaped rod 26 slides within the limiting cavity 28. Inside the connecting ring 4, a limiting spring 27 is sleeved on the outside of the T-shaped rod 26. One end of the limiting spring 27 is fixedly connected to the limiting cavity 28, and the other end is fixedly connected to the T-shaped rod 26. When the oil guide tube 23 enters the through hole 11, the plug 25 will be pushed to move outward. During the outward movement of the plug 25, the T-shaped rod 26 will move synchronously. The T-shaped rod 26 moves along the limiting cavity 28 and compresses the limiting spring 27. When the oil guide tube 23 is disengaged from the through hole 11, the plug 25 is re-engaged into the through hole 11 under the elastic force of the limiting spring 27, thus sealing the through hole 11. An oil reservoir 2 is fixedly connected to one side of the finned connecting box 1. An oil guide pipe 23 is snapped into the through hole 11. Several sets of oil guide holes 24 are opened on the outside of the oil guide pipe 23. The end of the oil guide pipe 23 away from the connecting ring 4 extends into the oil reservoir 2. An oil drain faucet 3 is fixedly connected to the end of the oil reservoir 2 away from the finned connecting box 1. When it is necessary to clean the oil in the oil reservoir 2, the oil drain faucet 3 can be opened to drain the oil from the oil reservoir 2. A push switch 7 is provided on both sides of the connecting rod 18. The specific model of the push switch 7 is TS-1012H manufactured by Dongguan Yuandi Electronics Co., Ltd. The push switch 7 is fixedly installed on the finned connecting box. Inside the finned connection box 1, the lower end of the oil storage chamber 21 is inclined. The slope at the lower end of the oil storage chamber 21 allows the oil to move to the position of the through hole 11. The cover 8 is installed on the upper end of the finned connection box 1 by several sets of screws 19. Several sets of limiting blocks 5 are fixedly connected to the lower end of the cover 8. The several sets of limiting blocks 5 correspond to several sets of T-shaped slots 14. The limiting blocks 5 are engaged in the T-shaped slots 14. The cover 8 is installed on the upper end of the finned connection box 1 by several sets of screws 19. During the installation process, it is ensured that the limiting blocks 5 can be engaged in the T-shaped slots 14. The limiting blocks 5 can limit and fix the heat dissipation fins 9 to prevent the heat dissipation fins 9 from shaking.

[0021] In addition, to achieve the above objectives, the present invention also provides a radiator including the above-described radiator fin connection structure.

[0022] Working principle: During use, according to the heat dissipation requirements of the radiator, a corresponding number of heat dissipation fins 9 can be installed in the fin connection box 1. Specifically, manually push the connecting rod 18 to the middle position of the fin connection box 1, insert the two ends of several sets of heat dissipation fins 9 into the corresponding T-shaped slots 14 respectively, and at the same time, ensure that the positioning hole 17 opened at the lower end of the heat dissipation fin 9 is engaged with the positioning rod 22 during the insertion process. After the engagement is completed, push the connecting rod 18 to the right side. At this time, the oil guide pipe 23 will be engaged in the through hole 11 and the plug 25 will be pushed out of the through hole 11. At this time, the limit spring 27 is squeezed by the T-shaped rod 26, and the box cover 8 is installed on the upper end of the fin connection box 1 through several sets of screws 19. During the installation process, ensure that the limit block 5 can be engaged in the T-shaped slot 14. The limit block 5 can limit and fix the heat dissipation fins 9 to prevent the heat dissipation fins 9 from shaking. At this time, the installation of several sets of heat dissipation fins 9 is completed. The cover 8, which is located inside the cover 8 and at the lower end of the finned connection box 1, can be connected to the oil pipe. When the transformer oil in the oil pipe enters the finned connection box 1 through the upper connection hole 6, the heat in the transformer oil will be absorbed by the heat dissipation fins 9 as the transformer oil passes through several sets of heat dissipation fins 9. The heat dissipation fins 9 will transfer the absorbed heat to the connecting column 13. The heat will then be transferred to several sets of outer fins 10 through the connecting column 13. The outer fins 10 are set in the external environment to dissipate heat from the transformer oil. The cooled transformer oil will then enter the lower oil pipe through the lower connection hole 6. After the heat dissipation is completed, the two sets of micro motors 33 are turned on. The micro motors 33 rotate and drive the gears 15 connected to their output ends to start rotating. Since the gears 15 mesh with the T-shaped tooth grooves 16, the connecting rod 18 moves to the left under the drive of the two sets of gears 15. During the movement of the connecting rod 18, the connecting ring 4 moves synchronously. The movement of the connecting ring 4 drives the two sets of T-shaped plates 32 set inside it to move synchronously. Since the two sets of T-shaped sliders 29 set inside the T-shaped plate 32 slide in the guide groove 12, and since the lower groove in the guide groove 12 is deeper than the upper groove, when the two sets of T-shaped sliders 29 move along the upper groove, the T-shaped plate 32 will be pushed outward and compress the first spring 34, so that the T-shaped plate 32 will not contact the heat dissipation fins 9. When the T-shaped slider 29 moves to the left side of the guide groove 12, since the left side of the guide groove 12 has an arc bend, as the connecting ring 4 moves continuously, the T-shaped slider 29 will be squeezed downward by the arc bend. The T-shaped slider 29 moves downward along the second T-shaped groove 31 and compresses the second spring 30. When the T-shaped slider 29 is squeezed to the lower side of the guide groove 12, since the depth of the lower side is greater than the depth of the upper groove, the T-shaped plate 32 will contact the heat dissipation fins 9 under the elastic force of the first spring 34. At this time, the connecting rod 18 has moved to the leftmost side and is in contact with the left-side push switch 7. At this time, the two sets of micro motors 33 rotate in opposite directions, driving the connecting rod 18 to move to the right. At this time, the two sets of T-shaped plates 32 located in the connecting ring 4 scrape off the oil on the surface of the heat dissipation fins 9. The scraped oil flows into the oil storage chamber 21 for storage. When the connecting rod 18 moves the connecting ring 4 to the far right and contacts the right-side push switch 7, the two sets of micro motors 33 stop. At the same time, due to the ramp on the right side of the guide groove 12, the T-shaped slider 29 re-enters the upper groove of the guide groove 12 along the ramp under the elastic force of the second spring 30. At this time, the T-shaped plate 32 will be squeezed away from the heat dissipation fins 9 again. When the connecting ring 4 moves to the far right, the oil guide pipe 23 will enter the through hole 11 and push out the plug 25. At this time, the oil in the oil storage chamber 21 will enter the oil storage tank 2 along the oil guide pipe 23 for storage, thereby cleaning and collecting the oil on the surface of the heat dissipation fins 9.
