Description

Technical Field

[0001] This invention belongs to the field of transformer heat dissipation technology, specifically a transformer heat dissipation device. Background Technology

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to transfer alternating current from one circuit to another and change its voltage and current. Its core function is to increase or decrease voltage to meet the needs of different power consumption scenarios. A prefabricated transformer is a compact power supply device that integrates transformers, high-voltage switchgear, low-voltage switchgear, and other components into a closed metal enclosure. It is commonly known as a prefabricated substation. Its core advantage is that it integrates traditionally distributed power equipment, achieving integrated and miniaturized power transformation functions. It is especially suitable for scenarios such as urban power grids, residential areas, and industrial parks that require rapid power supply and have limited space. Transformers generate a lot of heat due to electromagnetic conversion and resistance losses. When this heat cannot be dissipated in time, the internal temperature of the equipment will rise. Excessive temperature will have many negative impacts on the normal operation of the prefabricated transformer, so a transformer heat dissipation device is required.

[0003] Existing transformer cooling systems typically employ natural cooling or forced air cooling. Natural cooling usually involves opening several ventilation holes on the sides of the transformer housing to allow cool outside air to enter and exchange heat with the hot internal air, thus achieving heat dissipation. Forced air cooling usually involves installing a fan on top of the transformer. However, in hot summers, due to the already high ambient temperature combined with the heat generated by the transformer itself, natural or forced air cooling is not very effective. Furthermore, both methods can easily allow dust and impurities to enter the transformer. Over time, a large amount of dust accumulates inside the transformer, covering the windings, core, and other critical components. This not only affects heat dissipation but may also lead to a decrease in electrical insulation performance, increasing the risk of short circuits and other faults, thus reducing the effectiveness of the transformer cooling system and failing to meet user needs.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1 - Figure 5 This application provides a transformer heat dissipation device, including a heat dissipation base 2 disposed on the inner bottom surface of a transformer housing 1 and a heat dissipation mechanism disposed on the transformer housing 1; the heat dissipation mechanism includes a plurality of cooling fans 4 symmetrically disposed on a transformer shell 3 and an air intake hood 5 detachably disposed on the upper end of the transformer shell 3. A temperature sensor and an alarm connected to the temperature sensor are provided inside the transformer shell 3. When the temperature sensor value reaches a set value, the alarm is triggered, and the heat dissipation mechanism is activated; a transformer body 6 for voltage level conversion is disposed inside the transformer shell 3, and the inlet of the air intake hood 5 is located above the transformer body 6; a first air inlet slot is provided on the lower end face of the transformer shell 3; the tilt angle of the cooling fans 4 is set to 45 degrees, blowing air to cool the transformer body 6 while simultaneously blowing hot air from inside the transformer shell 3 toward the air intake hood 5; the heat dissipation mechanism also includes a chimney-type hot air exhaust pipe 7 detachably connected to the air intake hood 5 and a protective cover 8 disposed on the upper end of the chimney-type hot air exhaust pipe 7, the protective cover 8 reducing external impurities or Rainwater enters the transformer housing 3. The chimney-type hot air exhaust pipe 7 is made of heat-insulating material. The chimney-type hot air exhaust pipe 7 gathers the hot air inside the transformer housing 3 through the air intake hood 5 and dissipates heat by utilizing the natural law of hot air rising. The temperature difference between the inside and outside of the chimney-type hot air exhaust pipe 7 creates a certain pressure difference, which further accelerates the exhaust speed of the hot air. When the hot air is discharged from the top of the transformer housing 3, a relatively low-pressure area is formed at the bottom of the transformer housing 3. According to the principle of air flow, ambient temperature air from outside is drawn into the transformer housing 3, thus forming a continuous air circulation. Through natural hot air rising and air convection, the transformer body 6 can be effectively cooled. The upper end of the heat sink 2 is symmetrically provided with a first connecting slot that matches the first air inlet slot. A dustproof net 9 is installed in the first connecting slot. The transformer box 1 is symmetrically provided with protective net doors 61. The outer side of the protective net doors 61 is provided with a movable box door 62. Opening the front and rear box doors 62 allows the protective net doors 61 to communicate with the outside, which can dissipate heat from the transformer box 1.

[0035] In this embodiment, when it is necessary to dissipate heat from the transformer body 6, the door 62 is opened to connect the transformer housing 1 with the external environment for heat dissipation. The suction hood 5 draws hot air from inside the transformer housing 3 into the chimney-type hot air exhaust pipe 7, and then exhausts the hot air through the chimney-type hot air exhaust pipe 7. External air enters the transformer housing 3 through the dustproof net 9 on the heat sink 2, forming an air circulation to effectively cool the transformer body 6. If the heat dissipation effect of the transformer body 6 is not good, the cooling fan 4 is started to blow air onto the transformer body 6 for heat dissipation and blows the hot air inside the transformer housing 3 toward the suction hood 5, increasing the effect of the suction hood 5 in gathering hot air and improving the heat dissipation effect of the transformer body 6. The dustproof net 9 can filter the cold air entering the transformer housing 3, reducing the amount of dust entering the transformer housing 3.

[0036] In this invention, the upper inner side of the suction hood 5 is provided with a first connecting frame 10 and a suction fan 11 rotatably mounted on the first connecting frame 10. The suction fan 11 can assist the suction hood 5 in quickly sucking air. The height of the chimney-type hot air exhaust pipe 7 is at least the minimum effective height, usually not less than three meters. If the chimney-type hot air exhaust pipe 7 is lower than the minimum effective height, the chimney-type hot air exhaust pipe 7 adopts a tapering design with a gradually decreasing pipe diameter. At the same time, an exhaust fan 12 is installed at the upper end of the chimney-type hot air exhaust pipe 7. The top of the chimney-type hot air exhaust pipe 7 is provided with a dustproof net. The exhaust fan 12 is located on the lower side of the protective cover 8. A first drive motor 13 is installed on the outer side of the suction hood 5. The interior of the first connecting frame 10 is provided with a rotating block 14 connected to the rotating shaft of the suction fan 11. The rotating block 14 is provided with a first bevel gear structure 15. The first bevel gear structure 15 is connected to the first drive motor 13 through a connecting rod.

[0037] In this embodiment, when the suction hood 5 draws the hot air inside the transformer housing 3 into the chimney-type hot air exhaust pipe 7, the flow of hot air drives the suction fan 11 to rotate, which makes the suction fan 11 accelerate the intake of hot air and the chimney-type hot air exhaust pipe 7 quickly exhaust the hot air.

[0038] When the chimney-type hot air exhaust pipe 7 is below the minimum effective height, the first drive motor 13 is started, which drives the connecting rod to rotate. This causes the connecting rod to drive the first bevel gear structure 15 to work, which in turn drives the rotating block 14 to rotate. The rotating block 14 then drives the suction fan 11 to rotate on the first connecting frame 10, accelerating the intake of hot air into the suction hood 5. The hot air then drives the exhaust fan 12 to rotate, accelerating the exhaust of hot air from the chimney-type hot air exhaust pipe 7.

[0039] The heat dissipation mechanism of this invention also includes air guide boxes 16 symmetrically arranged on both sides of the upper end of the heat sink 2. The bottom end of the air guide box 16 is provided with a second air inlet groove. The upper end of the heat sink 2 is symmetrically provided with a second connecting groove that matches the second air inlet groove. The dustproof net 9 is installed in the second connecting groove. The air inlet end of the cooling fan 4 is located in the air guide box 16, which can guide the air in the air guide box 16 into the transformer housing 3. The front side of the heat sink 2 is symmetrically provided with air inlets 17. The heat sink 2 is provided with a cooling seat 18 connected to the air inlet 17. The cooling seat 18 is symmetrically provided with heat dissipation fins 19. The two heat dissipation fins 19 are respectively aligned with the first air inlet groove and the second air inlet groove. The cooling seat 18 is provided with a cooling component, which can cool the air entering the air inlet 17.

[0040] In this embodiment, the heat sink 2 introduces external air through the air inlet 17, and the heat sink 19 and the cooling seat 18 work together to cool the external air. When the cooling fan 4 is started, the cooling fan 4 introduces the cold air in the air guide box 16 into the transformer housing 3, so that the second air inlet channel introduces external air into the air guide box 16 through the second air inlet channel. The transformer housing 3 introduces cold air into the transformer housing 3 through the first air inlet channel and the first connecting channel, thereby cooling the air inside the transformer housing 3.

[0041] In this invention, the cooling assembly includes a first cooling chamber 20 and a second cooling chamber 21 disposed in a cooling base 18. The cooling base 18 has a "U"-shaped structure, and the structures of the first cooling chamber 20 and the second cooling chamber 21 are similar to those of the cooling base 18. The cooling assembly also includes a refrigerant storage tank 22 disposed on the rear side of the heat sink 2 and two cooling pumps 23 disposed on the refrigerant storage tank 22. The refrigerant storage tank 22 stores coolant and a refrigeration structure for cooling the coolant. The cooling pumps 23 are provided with liquid guide pipes. The first cooling chamber 20 and the second cooling chamber 21 are connected to the cooling pumps 23 and the refrigerant storage tank 22 respectively through the liquid guide pipes, so that the cooling pumps 23 can circulate the coolant in the refrigerant storage tank 22 through the liquid guide pipes in the first cooling chamber 20 or the second cooling chamber 21. The heat sink fins 19 are provided with heat conduction strips 24, and one end of each of the heat conduction strips 24 is sealed in the first cooling chamber 20 or the second cooling chamber 21.

[0042] In this embodiment, the cooling pump 23 is started, and the coolant in the cooling liquid storage tank 22 is introduced into the first cooling chamber 20 and the second cooling chamber 21 through the liquid guide pipe, so that the coolant cools the heat conduction strip 24, the heat conduction strip 24 cools the heat dissipation fins 19, and the heat dissipation fins 19 cool the external air entering from the air inlet 17.

[0043] Example 2

[0044] Based on Example 1, referring to Figure 1 - Figure 2 and Figure 6 - Figure 8 This is the second embodiment of the present invention. In this embodiment, the heat dissipation mechanism further includes a connecting box 25 disposed on the upper end of the cooling base 18 and movable parts 26 symmetrically disposed on both sides of the outer surface of the connecting box 25. The two ends of the connecting box 25 extend out of the air inlet 17. The lower end surface of the movable part 26 is provided with a first cleaning scraper 27 for cleaning impurities from the heat dissipation fins 19. The first cleaning scraper 27 is toothed and has a trapezoidal surface on the side of the first cleaning scraper 27 near the heat dissipation fins 19, which can reciprocate to clean impurities from the heat dissipation fins 19. The upper end surface of the movable part 26 is provided with a second cleaning scraper 28 for cleaning impurities from the dustproof net 9. The vertical cross section of the second cleaning scraper 28 is trapezoidal, which facilitates reciprocating cleaning of impurities from the dustproof net 9.

[0045] In this embodiment, the heat dissipation fins 19 cool the air. Every once in a while, the moving part 26 is controlled to move on the connecting box 25, so that the moving part 26 drives the first cleaning scraper 27 to clean the impurities on the heat dissipation fins 19. The moving part 26 drives the second cleaning scraper 28 to move, so that the second cleaning scraper 28 cleans the impurities on the dustproof net 9 and cleans the impurities to the outside of the heat sink 2.

[0046] In this invention, the movable part 26 is symmetrically provided with collection grooves that match the second cleaning scraper 28. A collection part 29 is rotatably provided in the collection groove. One end of the collection part 29 is provided with several rotating parts 30 that are rotatably connected to the movable part 26. The upper end of the collection part 29 is provided with a guide strip 31 that fits against the inner wall of the collection groove on the side near the rotating parts 30. The other side of the upper end of the collection part 29 is provided with an anti-detachment strip 32. When the movable part 26 moves on the heat dissipation fins 19, the heat dissipation fins 19 support the collection part 29. The collection groove, collection part 29, guide strip 31 and anti-detachment strip 32 work together to collect and clean the impurities of the dust screen 9 cleaned by the second cleaning scraper 28. When the movable part 26 moves out of the air inlet 17, the collection part 29 rotates under the action of gravity to discharge the collected impurities. When the movable part 26 enters the air inlet 17, the collection part 29 resets.

[0047] In this embodiment, when the moving part 26 drives the second cleaning scraper 28 to move, the second cleaning scraper 28 cleans the impurities on the dustproof net 9. The second cleaning scraper 28 cleans the impurities into the collection groove, so that the collection part 29, the guide strip 31 and the anti-detachment strip 32 cooperate to lift the impurities. When the moving part 26 moves out of the air inlet 17, the collection part 29 separates from the heat dissipation fins 19, so that the collection part 29 drives the rotating part 30 to rotate on the moving part 26, and discharges the impurities from the collection groove. When the moving part 26 enters the air inlet 17, the collection part 29 resets.

[0048] In this invention, the outer surface of the movable part 26 is provided with support frames 33 on both sides, and a knocking strip 34 is rotatably provided on the support frame 33. When the movable part 26 moves, the knocking strip 34 rotates to clean the dust net 9.

[0049] In this embodiment, when the movable member 26 moves, the striking strip 34 rotates on the support frame 33, causing the striking strip 34 to strike the dustproof net 9 and knock off the impurities adhering to the dustproof net 9, so that the movable member 26, the first cleaning scraper 27 and the second cleaning scraper 28 cooperate to clean the impurities.

[0050] In this invention, the connecting box 25 is equipped with a lead screw transmission structure 35 inside.

[0053] Based on Example 2, referring to Figure 6 - Figure 7 and Figure 9 - Figure 11This is the third embodiment of the present invention. In this embodiment, a plurality of sealing blocks 40 are movably disposed in the movable groove. A sealing groove matching the sealing blocks 40 is formed on the movable groove. A pressing block 41, offset from the sealing blocks 40, is symmetrically disposed on the movable strip 38. The movable strip 38, sealing blocks 40, and pressing blocks 41 cooperate to seal the movable groove, preventing external dust or impurities from entering the connecting box 25. A first rack 42 is provided on the upper outer side of the pressing block 41. A plurality of first gears 43 are provided in the connecting box 25 to control the lifting and lowering of the sealing blocks 40. The first gears 43 mesh with the first racks 42. The first gears 43 are disposed on the outer side of the movable groove. A second gear 44 is coaxially disposed on the first gear 43, and the second gear 44 meshes with the first... The transmission gear 45 and the sealing block 40 are provided with a second rack 46 that meshes with the first transmission gear 45. The connecting box 25 is provided with a lifting groove for the second gear 44, the first transmission gear 45 and the second rack 46 to work. The reinforcing block 39 is offset from the first gear 43. The outer upper part of another extrusion block 41 is provided with a reinforcing connecting block 47. The reinforcing connecting block 47 is provided with a movable rack 48 that meshes with the first gear 43. The reinforcing connecting block 47 is offset from the first gear 43. The first rack 42 and the movable rack 48 are respectively provided on the upper and lower sides of the first gear 43, so that the first rack 42 opens or closes the sealing block 40 through the first gear 43, and the movable rack 48 closes or opens the sealing block 40 through the first gear 43.

[0054] In this embodiment, when the lead screw transmission structure 35 drives the moving strip 38 to move in the moving groove through the moving block 37 and the reinforcing block 39, the moving strip 38 drives the pressing block 41 to move, the pressing block 41 drives the first rack 42 to move, so that the first rack 42 meshes with the first gear 43, driving the first gear 43 to rotate, the first gear 43 drives the second gear 44 to rotate, so that the second gear 44 drives the first transmission gear 45 to rotate, so that the first transmission gear 45 drives the second rack 46 to move upward, so that the second rack 46 drives the sealing block 40 to move upward, so that the sealing block 40 enters the sealing groove, opening the moving groove, making it easier for the moving strip 38 to move in the moving groove;

[0055] After the moving bar 38 leaves, the pressing block 41 causes the reinforcing connecting block 47 to move, which in turn causes the reinforcing connecting block 47 to move the moving rack 48. The moving rack 48 causes the first gear 43 to rotate, which in turn causes the second gear 44 to rotate, which in turn causes the second gear 44 to rotate, which in turn causes the first transmission gear 45 to rotate. This causes the first transmission gear 45 to move the second rack 46 upward, which in turn causes the second rack 46 to move the sealing block 40 downward. This allows the sealing block 40 to move from the sealing groove into the moving groove, sealing the moving groove and preventing impurities from the outer wall from entering the connecting box 25.

[0056] In this invention, the outer side of the support frame 33 is provided with a rotating rod 49 for controlling the rotation of the striking bar 34. One end of the rotating rod 49 passes through the moving bar 38 and extends into the interior of the connecting box 25. The rotating rod 49 is rotatably mounted on the moving bar 38. One end of the rotating rod 49 is provided with a rotating gear 50. The connecting box 25 is provided with a support rack 51 that meshes with the rotating gear 50. When the moving bar 38 moves, the support rack 51 controls the rotation of the striking bar 34 through the rotating gear 50 to clean the dust from the dustproof net 9.

[0057] In this embodiment, when the moving bar 38 moves, it causes the rotating rod 49 to move within the connecting box 25. The rotating gear 50 meshes with the supporting rack 51, causing the supporting rack 51 to drive the rotating gear 50 to rotate. The rotating gear 50 then drives the rotating rod 49 to rotate, causing the rotating rod 49 to drive the striking bar 34 to rotate on the support frame 33, thus causing the striking bar 34 to strike the dustproof net 9.

[0058] In this invention, the moving strip 38 is provided with a transmission gear ring 52 that is sleeved with the rotating rod 49. A second transmission gear 53 is meshed on one side of the transmission gear ring 52. The second transmission gear 53 is coaxially provided with a transmission rod 54, and a second bevel gear structure 55 is provided through the transmission rod 54. A timing belt structure 56 is provided at one end of the second bevel gear structure 55. Several mounting parts 57 are detachably provided on the timing belt structure 56. A reinforcing rod 58 protruding from the moving strip 38 is provided on the mounting part 57. The reinforcing rod 58 is provided with a scraper 60 through the mounting block 59 to clean impurities on the front side of the moving strip 38, which can clean impurities or dust in the moving groove to the outside of the connecting box 25.

[0059] In this embodiment, when the moving bar 38 moves, it cleans and pushes impurities in the moving groove. The movement of the moving bar 38 drives the rotating rod 49 to rotate, which in turn drives the transmission gear ring 52 to rotate. The transmission gear ring 52 drives the second transmission gear 53 to rotate, which in turn drives the transmission rod 54 to rotate. The transmission rod 54 drives the second bevel gear structure 55 to rotate, which in turn drives the mounting part 57 to move. The mounting part 57 then drives the reinforcing rod 58 to move, which in turn drives the mounting block 59 to move. The mounting block 59 then drives the scraper 60 to move, so that the scraper 60 cleans the impurities on the front side of the moving bar 38 to the outside of the connecting box 25.
