Abstract
Description
Technical Field
[0001] This utility model relates to the field of inductor technology, and in particular to a high-temperature resistant inductor. Background Technology
[0002] In current technologies, inductors, as an indispensable basic electronic component, play a crucial role in many fields such as power electronics, communications, and new energy due to their core characteristics of "energy storage" and "impeding current changes." In power electronic systems, they bear the heavy responsibility of filtering and current stabilization, ensuring stable current output. In communication equipment, inductors participate in signal modulation and demodulation, helping to achieve efficient and stable signal transmission. However, in special working environments such as automotive engine compartments, high-temperature industrial equipment, and aerospace equipment, ordinary inductors face severe challenges. In automotive engine compartments, the high temperatures and severe vibrations generated by engine operation accelerate the aging of the inductor's insulation layer, causing the inductance value to shift and affecting the stability of the vehicle's electronic control system.
[0003] However, existing technologies still have shortcomings, such as the following:
[0004] Existing high-temperature inductors suffer from significant drawbacks in practical applications, including limited current control and low heat dissipation efficiency. Their internal circuit design is rigid, lacking adaptive adjustment capabilities in the face of complex current environments such as voltage fluctuations and frequency variations, and thus unable to precisely control the current flow. When localized overheating occurs in the inductor, the lack of a flexible current path adjustment mechanism not only fails to alleviate the overheating problem but also leads to current imbalance, affecting the stable operation of the entire circuit system and posing a high risk of equipment failure. Utility Model Content
[0005] The purpose of this invention is to provide a high-temperature resistant inductor to solve the problems of single current control and low heat dissipation efficiency mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-temperature resistant inductor includes an external structure, an inductor mounted on the inner side of the external structure, a heat dissipation structure snapped onto the top of the external structure, an external frame, a converter mounted on one side of the outer wall of the external frame, a power line mounted on one end of the converter, and branch lines mounted on both sides of the converter.
[0008] The inductor includes an inductor box, with insulated wires installed on the inner sides of both the left and right sides of the inductor box. An inductor line connection terminal is installed on one side of the outer wall of the inductor box, and one end of the branch line is installed on the inner side of the inductor line connection terminal.
[0009] Preferably, the heat dissipation structure includes a heat dissipation shell, a heat conduction port is installed on the inner side of the top of the heat dissipation shell, and a fixing frame is installed on the inner side of the heat dissipation shell.
[0010] Preferably, a drive motor is mounted on the top of the fixing frame, and a heat dissipation fin is mounted on the bottom end of the drive motor.
[0011] Preferably, slots are installed on both sides of the outer wall of the heat dissipation shell, and a slot block is fixedly connected to the inner side of the slot.
[0012] Preferably, clamping boxes are installed on both sides of the top of the outer frame, and the top of the clamping boxes has a movable groove.
[0013] Preferably, a shrinkage groove is provided on the outer wall of one side of the clamping box, and a positioning groove is installed on the left side of the inner wall of the clamping box.
[0014] Preferably, a reset spring is installed on the inner side of the positioning groove, and an unblocking plate is installed on one end of the reset spring and located on the inner side of the clamping box. A retraction block is installed on the outer wall of one side of the unblocking plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. Through the coordinated design of the converter, branch lines, and inductors, precise control and regulation of current are achieved. After entering the converter through the power supply lines, the current can be guided to the branch lines and corresponding inductors as needed. Utilizing the characteristic of inductors to impede current changes, the AC component is effectively attenuated while retaining the DC component, achieving excellent filtering effects and making the output current more stable. Compared with traditional inductors, the accuracy and stability of its current control are greatly improved, better meeting the operating requirements of various complex circuits.
[0017] 2. When the inductor's operating temperature is too high, the current path can be switched via a converter to activate the backup inductor, while simultaneously activating the heat dissipation structure on the overheated inductor. The drive motor in the heat dissipation structure rotates the cooling blades, providing air cooling to the inductor's internal cavity. The heat dissipation structure and external frame are cleverly designed for secure installation and easy disassembly. Compared to traditional cooling methods, this design not only offers higher heat dissipation efficiency but also features intelligent switching and rapid maintenance, effectively ensuring reliable inductor operation in high-temperature environments and extending its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-4 As shown, a high-temperature resistant inductor includes an external structure 1, on the inner side of which an inductor 2 is installed. The inductor 2 is used to control and regulate the current. A heat dissipation structure 3 is snapped onto the top of the external structure 1 to dissipate heat from the inductor 2. The external structure 1 includes an external frame 11, on one side of which a converter 12 is installed. The converter 12 switches the current flow circuit. A power line 13 is installed at one end of the converter 12 to allow current to enter the converter 12. Branch lines 15 are installed on both sides of the converter 12 to transmit the current to the inductor 2.
[0025] The inductor 2 includes an inductor box 21, and insulated wires 22 are installed on the inner sides of both sides of the inductor box 21. The core functions of "energy storage" and "impeding current changes" are realized through the insulated wires 22. An inductor line docking terminal 23 is installed on one side of the outer wall of the inductor box 21 for connecting the branch line 15.
[0026] It should be noted that in this embodiment, if the power line 13 is connected to the current, the current first enters the converter 12 through the power line 13, and then the converter 12 guides one of the branch lines 15. The current is guided to the corresponding inductor 2 through the branch line 15 carrying the current. Due to the characteristic of the inductor 2 to impede the change of current, the DC component can pass smoothly and the AC component is attenuated, thereby achieving a filtering effect and making the output current more stable. However, if the temperature is too high during operation, the inductor 2 will overheat. Therefore, the converter 12 will switch to another branch line 15 to guide the current to the inductor 2 on the other side for operation.
[0027] The heat dissipation structure 3 includes a heat dissipation shell 31, and a heat conduction port 32 is installed on the inner side of the top of the heat dissipation shell 31 to conduct heat out. A fixing bracket 33 is installed on the inner side of the heat dissipation shell 31 to facilitate the installation of a drive motor 34. The drive motor 34 is installed on the top of the fixing bracket 33 to drive the heat dissipation blades 35. The heat dissipation blades 35 are installed at one end of the drive motor 34 through the bottom drive, so that the heat dissipation blades 35 can rotate. The two sides of the outer wall of the heat dissipation shell 31 are equipped with slots 36 to facilitate the insertion of the retractable plug 146. A slot block 361 is fixedly connected to the inner side of the slot 36 to limit the retractable plug 146.
[0028] It should be noted that in this embodiment, when assembling the inductor 2 and the heat dissipation structure 3, the inductor 2 is first assembled to the inner side of the outer frame 11, and then the heat dissipation structure 3 is assembled to the upper surface of the inductor 2. By placing the heat dissipation structure 3 on the upper surface of the inductor 2 and pressing the heat dissipation structure 3, the shrinking insert 146 is inserted into the inner side of the slot 36 and squeezed by the slot block 361, thereby pushing the unblocking plate 144. Then, by being pushed by the reset spring 143, the shrinking insert 146 slides inside the shrinking groove 145, thereby inserting into the back limiting area of the slot block 361, thus limiting the heat dissipation structure 3.
[0029] The top of the outer frame 11 is equipped with clamping boxes 14 on both sides. The top of the clamping box 14 has a movable groove 141 to facilitate the movement of the release plate 144. The outer wall of one side of the clamping box 14 has a shrinkage groove 145. The left side of the inner wall of the clamping box 14 has a positioning groove 142 to limit the return spring 143. The return spring 143 is installed inside the positioning groove 142 to push the release plate 144 to reset it. The release plate 144 is installed at one end of the return spring 143 and is located inside the clamping box 14, which facilitates the manual movement of the shrinkage block 146 to pull out the slot 36. The outer wall of one side of the release plate 144 has a shrinkage block 146 to facilitate the positioning of the heat dissipation structure 3.
[0030] It should be noted that in this embodiment, the inductor 2 is overheated. When the converter 12 switches a branch line 15 to guide the current to the other inductor 2 for operation, and when switching to another inductor 2, the drive motor 34 on the upper surface of the overheated inductor 2 is started. Then, the drive motor 34 drives the heat sink 35 to rotate, so that the heat sink 35 can air-cool the inner cavity of the inductor 2.
[0031] The working principle of this utility model is as follows: When assembling the inductor 2 and the heat dissipation structure 3, the inductor 2 is first assembled to the inner side of the outer frame 11, and then the heat dissipation structure 3 is assembled to the upper surface of the inductor 2. By placing the heat dissipation structure 3 on the upper surface of the inductor 2 and pressing the heat dissipation structure 3, the shrinking insert 146 enters the inner side of the slot 36 and is squeezed by the slot block 361, thereby pushing the unblocking plate 144. Then, by being pushed by the reset spring 143, the shrinking insert 146 slides inside the shrinking groove 145, thereby inserting into the back limiting area of the slot block 361, thus limiting the heat dissipation structure 3.
[0032] If the power line 13 is connected to the current, the current first enters the converter 12 through the power line 13, and then the converter 12 guides one of the branch lines 15. The current is guided to the corresponding inductor 2 through the branch line 15 carrying the current. The characteristic of the inductor 2 to impede the change of current allows the DC component to pass smoothly and attenuates the AC component, thereby achieving a filtering effect and making the output current more stable. During operation, if the temperature is too high, the inductor 2 will overheat. Therefore, the converter 12 will switch to another branch line 15 to guide the current to the inductor 2 on the other side for operation.
[0033] When switching to another inductor 2, the drive motor 34 on the upper surface of the overheated inductor 2 is started, and then the heat dissipation blade 35 is driven to rotate through one end of the drive motor 34, so that the heat dissipation blade 35 can air cool the inner cavity of the inductor 2.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
