An inductor capable of preventing heat from being accumulated in a large amount

Abstract

The application discloses an inductor capable of preventing heat accumulation, and belongs to the technical field of inductor heat accumulation. In order to solve the problem that a traditional inductor is inconvenient to set and collect hot gas rising due to heat through an embedded structure, heat accumulation in the inductor is prevented through the mode of dispersing hot gas. When a certain amount of hot gas is concentrated, the inductor is released from the hot gas, thereby avoiding the problem of long-time heat accumulation in the inductor. The embedded ring is embedded on the upper end of the inductor shell, and large heat radiating fins are fixed on the upper end of the inductor shell. The heat generated by the inductor coil drives gas to rise. The heat radiating assembly absorbs the gas in the inductor shell and the large heat radiating fins through four air inlet pipes and fixing pipes, and finally releases the gas, so that the purpose of avoiding heat accumulation is achieved.

Description

Technical Field

[0001] This invention relates to the field of inductor heat accumulation technology, specifically to an inductor that can prevent excessive heat accumulation. Background Technology

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance; it only impedes changes in current. If no current is flowing through the inductor, it will attempt to impede the current flow when the circuit is closed; if current is flowing through the inductor, it will attempt to maintain a constant current when the circuit is open. Inductors are also called chokes, reactors, or dynamic reactors. When inductors operate for extended periods or at high power, the large amount of heat generated can easily accumulate.

[0003] Traditional inductors are not suitable for setting up a nested structure to collect the hot air that rises due to heat, and then use the concentrated compression of the hot air to induce the dissipation of heat to prevent the accumulation of heat inside the inductor.

[0030] 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.

[0031] To address the inconvenience of traditional inductors in using a nested structure to collect rising heat, and then using the concentrated compression of the hot gas to induce heat dissipation and prevent heat buildup inside the inductor, a further technical solution is needed. This involves releasing the heat from the inductor once a certain amount of heat has accumulated, thus avoiding prolonged heat buildup. Figures 1-5 As shown, the following preferred technical solutions are provided:

[0032] An inductor designed to prevent excessive heat buildup includes an inductor housing 1 and an inner cavity 8 formed inside the inductor housing 1, with an inductor coil 7 disposed inside the inner cavity 8. The inductor housing 1 is characterized by: a fitting ring 5 fitted inside the upper end of the inductor housing 1; a large heat sink 4 fitted inside the fitting ring 5; a heat dissipation component 2 disposed at the upper end of the large heat sink 4; and a connecting component 3 fixedly disposed at the lower end of the heat dissipation component 2. The connecting component 3 is inserted and fixed to the upper end of the inductor housing 1, and the heat dissipation component 2 is connected to the inductor housing 1 through the connecting component 3. The heat dissipation component 2 contains a driving component 6, and two sets of driving components 6 are provided. The connecting component 3 includes a fixed... A fixed pipe 31 is located below the center of the heat dissipation assembly 2. An air inlet pipe 32 is provided on the outside of the fixed pipe 31, and four sets of air inlet pipes 32 are provided. The air inlet pipe 32 includes an inclined pipe body 321 connected to the outside of the fixed pipe 31. One end of the inclined pipe body 321 is provided with a plug pipe body 322, and one end of the plug pipe body 322 is fitted inside the inductor housing 1. The fitting ring 5 is fitted on the upper end of the inductor housing 1, so that the large heat sink 4 is fixed on the upper end of the inductor housing 1. The heat generated by the operation of the inductor coil 7 drives the gas to rise. The heat dissipation assembly 2 absorbs the gas inside the inductor housing 1 and the large heat sink 4 through the four sets of air inlet pipes 32 and fixed pipes 31, and finally releases it.

[0033] The inductor housing 1 has corner slots 11 at each of its four corners, and each set of corner slots 11 has a connecting slot 12 on one side. The four sets of connectors 322 are fitted into the corresponding set of connecting slots 12. The upper end of the inductor housing 1 has a fitting groove 13, which is connected to the inner cavity 8. The fitting ring 5 is fitted into the fitting groove 13. The four interiors of the inductor housing 1 have finned cavities 14, which are located directly below the corresponding set of connecting slots 12. The lower end of the corner slots 11 has a small heat sink 111. The heat dissipation assembly 2 has an inner hollow ring 21 inside. Furthermore, the inner hollow ring 21 is connected to the interior of the fixed tube 31. An air inlet valve 312 is provided at the upper end of the interior of the fixed tube 31, and a first one-way air valve 311 is provided at the lower end of the interior of the fixed tube 31. A second one-way air valve 3211 is provided at one end of the inclined tube 321. The drive assembly 6 includes a first protective net 61 provided at the upper end of the heat dissipation assembly 2. The drive assembly 6 also includes a dual-head motor 63 provided at the lower end of the heat dissipation assembly 2. A first fan 62 is provided at one end of the dual-head motor 63 through the output end, and the first fan 62 is located inside the inner hollow ring 21. A linkage rod 64 is provided at the other end of the dual-head motor 63 through the output end.

[0034] Specifically, when the inductor coil 7 operates for a long time or at high efficiency, it generates heat. At this time, the finned cavity 14, which is made of heat dissipation material, has a finned structure, which increases the heat-receiving area. This heats the air inside the finned cavity 14. Due to the principle of hot air rising, the heated gas enters the fixed tube 31 through the four sets of plug tubes 322 and inclined tubes 321. The high temperature of the inductor coil 7 also heats the air inside the large heat sink 4, which then enters the fixed tube 31. Subsequently, the hot air enters the hollow ring 21 through the fixed tube 31. Driven by the dual-head motor 63, the first fan 62 rotates, thereby releasing the concentrated hot air inside the hollow ring 21. This accelerates the air circulation of the entire inductor, prevents the accumulation of hot air, and enhances the heat dissipation effect of the inductor.

[0035] To address the technical challenge of more efficiently transferring heat from inductors, such as... Figures 6-9 As shown, the following preferred technical solutions are provided:

[0036] An airbag ring 51 is fixedly installed on the outer side of the lower end of the fitting ring 5. A threaded post 52 is threaded inside the fitting ring 5. A movable plug 53 is movably installed at the lower end of the threaded post 52. An air cylinder 54 is installed at the lower end of the movable plug 53, and the movable plug 53 is vertically fitted inside the air cylinder 54. A connecting air pipe 55 is installed at one end of the air cylinder 54, and the air cylinder 54 is connected to the airbag ring 51 through the connecting air pipe 55. A thermally conductive silicone sheet 56 is installed at the bottom of the fitting ring 5. A central groove 41 is opened at the center of the upper end of the large heat sink 4, and one end of the fixed tube 31 is... The large heat sink 4 is fitted inside the central slot 41 and has an internal gas chamber 42. The central slot 41 is connected to the gas chamber 42. The upper end of the large heat sink 4 is provided with a ventilation assembly 43, and two sets of ventilation assemblies 43 are provided. The ventilation assembly 43 includes a protective mechanism 431 provided at the upper end of the large heat sink 4, a fixing component 433 fixedly provided inside the large heat sink 4, and a second fan 432. The fixing component 433 is located at the lower end of the protective mechanism 431, and the second fan 432 is located at the lower end of the fixing component 433.

[0037] The fixing component 433 includes a fixing ring 4332 fixedly installed inside the large heat sink 4. A fixing block 4331 is provided at the center of the fixing ring 4332. A support column 4333 is provided on the outside of the fixing block 4331, and four sets of support columns 4333 are provided. The second fan 432 is connected to the fixing block 4331 via a shaft. The protective mechanism 431 includes a second protective net 4311. A rotating column 4312 is movably installed at the center of the second protective net 4311. The rotating column 4312 is connected to the fixing block 4331 via a shaft, and this shaft is movably installed inside the fixing block 4331. A through groove 4313 is opened inside the rotating column 4312. An ear groove 4314 is opened on the outside of the through groove 4313, and two sets of ear grooves 4314 are provided. The linkage rod 64 matches the through groove 4313 and the ear groove 4314.

[0038] Specifically, when the large heat sink 4 is fitted inside the fitting ring 5, the fitting ring 5 needs to be fitted inside the fitting groove 13. At this time, the threaded column 52 is rotated in the reverse direction. The threaded column 52 drives the movable plug 53 to rise, which then cooperates with the air cylinder 54 to draw in the gas inside the airbag ring 51, so that the fitting ring 5 can be fitted inside the fitting groove 13 until the thermally conductive silicone sheet 56 deforms and makes tight contact with the upper end of the inductor coil 7. At this time, the threaded column 52 is rotated in the forward direction, which causes the movable plug 53 to descend inside the air cylinder 54, squeezing the air inside the air cylinder 54 into the airbag ring 51, so that the airbag ring 51... The expansion strengthens the connection between the inner wall of the fitting ring 5 and the fitting groove 13. At this time, the close contact between the thermally conductive silicone sheet 56 and the inductor coil 7 is conducive to better transferring the heat of the inductor coil 7 to the large heat sink 4. After the heat dissipation component 2 is fitted into the upper end of the inductor housing 1 through the connecting component 3, one end of the linkage rod 64 will be fitted into the through groove 4313 and the ear groove 4314. That is, the rotation of the first fan 62 will drive the second fan 432 to rotate. The rotation of the second fan 432 can accelerate the air circulation inside the heat dissipation component 2, which can help enhance the heat dissipation of the inductor and avoid heat accumulation.

[0039] To solve the technical problem of how to sense a certain amount of concentrated hot air and then drive its release, such as... Figure 10 As shown, the following preferred technical solutions are provided:

[0040] The intake valve 312 includes a straight groove 3121 inside the intake valve 312. A lifting groove 3122 is provided on one side of the straight groove 3121. A valve core 3124 is fitted inside the lifting groove 3122 and the straight groove 3121. A connecting spring 3125 is provided at the upper end of the valve core 3124. Two sets of connecting springs 3125 are provided. One end of the two sets of connecting springs 3125 is fixedly connected to the inside of the intake valve 312. An L-shaped groove 3123 is provided on one side of the lifting groove 3122. One end of the L-shaped groove 3123 is connected to the inside of the hollow ring 21. A sensing block 3126 is also provided inside the intake valve 312.

[0041] Specifically, when hot air from the heat dissipation assembly 2 and the finned cavity 14 enters the fixed tube 31, due to the setting of the second one-way valve 3211 and the first one-way valve 311, the hot air will be stored inside the inclined tube 321 and the first one-way valve 311. As more and more gas is released, the gas will compress the valve core 3124, causing it to rise. At this time, the connecting spring 3125 is compressed. When the valve core 3124 rises to contact the sensing block 3126, the dual-head motor 63 is driven by the sensor to work for a period of time to release the hot air and prevent the accumulation of hot air. At this time, the inclined tube... The gas inside body 321 and the first one-way valve 311 will enter the inner hollow ring body 21 through the L-shaped groove 3123 to be released. When the dual-head motor 63 drives the first fan 62 to rotate, the upward airflow generated inside the inner hollow ring body 21 will cause the valve core 3124 to always be in contact with the sensing block 3126, that is, the L-shaped groove 3123 will be exposed. After the driving time of the dual-head motor 63 is over, there is no longer heat inside the fixed tube 31 to push the valve core 3124 to rise. At this time, the elastic force of the connecting spring 3125 returning to its natural state will drive the valve core 3124 to fall, ready for the next use.
