Description

Technical Field

[0001] This utility model belongs to the field of inductor technology, specifically, it relates to a high-efficiency, low-harmonic, multi-purpose high-frequency inductor. Background Technology

[0002] In today's era of rapid development in electronic technology, inductors, as a basic electronic component, are widely used in many fields and are one of the key components for achieving efficient and stable power conversion and signal processing.

[0003] Traditional high-frequency inductors suffer from high energy loss during operation due to limitations in material properties and structural design. When high-frequency current passes through, a large amount of heat energy is lost due to the Joule heating effect, which reduces the efficiency of power utilization and causes the inductor to overheat, thus affecting its stability and service life.

[0004] To address the aforementioned issues, this application proposes a high-efficiency, low-harmonic, multi-purpose high-frequency inductor. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a high-efficiency, low-harmonic, multi-purpose high-frequency inductor to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency, low-harmonic, multi-purpose high-frequency inductor includes an upper yoke magnetic block, a support block fixedly connected to the bottom of the upper yoke magnetic block, a mounting plate fixedly connected to the bottom of the support block, a lower yoke magnetic block symmetrically arranged on the upper yoke magnetic block via the mounting plate, a segmented magnetic sheet arranged between the upper and lower yoke magnetic blocks, an air gap sheet arranged between two adjacent segmented magnetic sheets, and a heat dissipation groove formed on the outer side wall of the air gap sheet.

[0008] Preferably, a coil is wound around the outer wall of the segmented magnetic sheet, and the coil is square-shaped and wound around the outer wall of the segmented magnetic sheet.

[0009] By setting the coil to be a square film-wrapped coil, the overall board area occupied by the inductor can be reduced.

[0010] Preferably, the segmented magnetic sheet and the air gap sheet have equal lengths and widths, and the air gap sheet is a ceramic sheet.

[0011] By setting segmented magnetic sheets and air gaps, the resonant inductor achieves uniform heating as a whole by installing the segmented magnetic sheets and air gaps in a spaced manner.

[0012] Preferably, the top of the mounting plate has a mounting hole, and the port of the coil is adapted to the mounting hole.

[0013] By setting mounting holes, it is possible to fix the coil to the port through the opening of the mounting holes, which facilitates the connection of the coil.

[0014] Preferably, there are two mounting holes, which are respectively fixedly connected to both ends of the coil.

[0015] By setting up coils and mounting holes, the two ends of the coil can be installed through the two mounting holes, thus enabling the coil to be effectively installed on the outer wall of the mounting plate, and allowing the two ends of the coil to be connected.

[0016] Preferably, a mounting plate is fixedly connected to a mounting base at its bottom, and a plug is fixedly connected to the center of the bottom of the mounting base.

[0017] By setting a mounting base and a plug, the plug can be fixed by the mounting base installed at the bottom of the mounting plate, so that the plug can be fixed at the bottom of the mounting plate and the end of the plug near the mounting plate is located inside the mounting hole.

[0018] Preferably, the coil is fixedly connected to one end of the plug near the mounting plate via a mounting hole.

[0019] By setting up a coil and a plug, the coil can be quickly connected by fixing the end of the coil to the plug. The plug can effectively keep the coil perpendicular to the mounting plate, thus facilitating the installation of the inductor.

[0020] In summary, the technical effects and advantages of this utility model are as follows: This high-efficiency, low-harmonic, multi-purpose high-frequency inductor, through the arrangement of an upper yoke magnetic block, a lower yoke magnetic block, segmented magnetic sheets, air gaps, and heat dissipation grooves, with the segmented magnetic sheets and air gaps spaced apart inside the upper and lower yoke magnetic blocks, can effectively ensure uniform heating of the resonant inductor as a whole. The exposed upper and lower yoke magnetic blocks act as natural heat dissipation devices, accelerating the heat dissipation of the resonant inductor, thereby improving heat dissipation efficiency and thus extending the service life and operating efficiency of the resonant inductor.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4 A high-efficiency, low-harmonic, multi-purpose high-frequency inductor includes an upper yoke 1, a support block 6 fixedly connected to the bottom of the upper yoke 1, and a mounting plate 7 fixedly connected to the bottom of the support block 6. Lower yoke 2s are symmetrically arranged on the upper yoke 1 via the mounting plate 7. Segmented magnetic sheets 3 are arranged between the upper yoke 1 and the lower yoke 2. Air gaps 4 are arranged between adjacent segments 3. Heat dissipation grooves 5 are formed on the outer wall of the air gaps 4. The upper yoke 1 and the lower yoke 2 are fixed to the top sides of the mounting plate 7 via the support block 6, thus ensuring the upper yoke 1 and the lower yoke 2 have sufficient heat dissipation capacity. The lower yoke magnetic block 2 is symmetrically distributed. Segmented magnetic sheets 3 and air gap sheets 4 are arranged at intervals inside the upper yoke magnetic block 1 and the lower yoke magnetic block 2. Air gap sheets 4 are fixedly connected between two adjacent segmented magnetic sheets 3, so that air gap sheets 4 are inserted inside the segmented magnetic sheets 3. In turn, the air gap sheets 4 make the surface temperature of multiple segmented magnetic sheets 3 uniform, so that the overall heating of the resonant inductor is uniform. It can also effectively conduct heat out of the resonant inductor through the upper yoke magnetic block 1 and the lower yoke magnetic block 2, thereby improving the heat dissipation efficiency of the resonant inductor.

[0028] Reference Figure 1-2 A coil 8 is wound around the outer wall of the segmented magnetic sheet 3. The coil 8 is square and wound around the outer wall of the segmented magnetic sheet 3. By making the coil 8 a square film-wrapped coil 8, and the coil 8 is wound in two sets in series on the outer wall of the segmented magnetic sheet 3 and the air gap sheet 4, the overall board area occupied by the resonant inductor can be reduced, the power density of the power board can be increased, and the use of square film wrapping greatly improves the space utilization of the coil 8, which can maximize the reduction of the volume of the resonant inductor, thereby reducing the space of the power supply.

[0029] Reference Figure 3-4The segmented magnetic sheet 3 and the air gap sheet 4 have equal lengths and widths, and the air gap sheet 4 is a ceramic sheet. By making the segmented magnetic sheet 3 and the air gap sheet 4 equal in volume, when the segmented magnetic sheet 3 and the air gap sheet 4 are installed inside the upper yoke magnetic block 1 and the lower yoke magnetic block 2, the coil 8 can be effectively wound. By using a ceramic sheet for the air gap sheet 4, the ceramic sheet has moderate hardness and does not deform, which can effectively improve the stability of the inductance and increase the thermal conductivity, making heat dissipation faster.

[0030] Reference Figure 1-2 The top of the mounting plate 7 is provided with a mounting hole 9. The port of the coil 8 is adapted to the mounting hole 9. By adapting the mounting hole 9 on the top of the mounting plate 7 to the port of the coil 8, the port of the coil 8 can be installed inside the mounting hole 9. The port of the coil 8 can be connected to the mounting plate 7, so that the coil 8 can be installed and fixed.

[0031] Reference Figure 1-2 There are two mounting holes 9, which are fixedly connected to the two ends of the coil 8 respectively. The two mounting holes 9 at the bottom of the mounting plate 7 are located on both sides of the coil 8, so that the two ends of the coil 8 can be effectively fixed to the top of the mounting plate 7 through the mounting holes 9. This can effectively wind the coil 8 around the outer wall of the segmented magnetic sheet 3 and the air gap sheet 4, thereby fixing the coil 8 and effectively preventing the coil 8 from becoming loose.

[0032] Reference Figure 3 A mounting plate 7 is fixedly connected to a mounting base 10 at its bottom. A plug 11 is fixedly connected to the center of the bottom of the mounting base 10. The plug 11 is installed on the bottom of the mounting plate 7 through the mounting base 10, and the mounting hole 9 is located at the center of the mounting base 10. The top of the plug 11 is fixed inside the mounting hole 9 through the mounting base 10, so that the plug 11 and the coil 8 are fixed inside the mounting hole 9, thereby facilitating the installation of the resonant inductor.

[0033] Reference Figure 3 The coil 8 is fixedly connected to the end of the plug 11 near the mounting plate 7 through the mounting hole 9. By fixing the plug 11 and the coil 8 inside the mounting hole 9, the resonant inductor is installed through the plug 11. The plug 11 is adapted to the mounting hole 9 of the resonant inductor, so that the resonant inductor is effectively installed on the mounting hole 9, effectively preventing the resonant inductor from becoming loose after installation.

[0034] Working principle: The upper yoke magnetic block 1 and the lower yoke magnetic block 2 are symmetrically mounted on the top of the mounting plate 7 by the support block 6. Multiple segmented magnetic sheets 3 and air gap sheets 4 are arranged inside the upper yoke magnetic block 1 and the lower yoke magnetic block 2, and air gap sheets 4 are arranged between two adjacent segmented magnetic sheets 3. The segmented magnetic sheets 3 and air gap sheets 4 arranged at intervals make the overall heating of the resonant inductor uniform. The upper yoke magnetic block 1 and the lower yoke magnetic block 2 can quickly dissipate heat from the resonant inductor, thereby improving the working efficiency and life of the resonant inductor. By using a square film-wound coil 8 and winding the coil 8 around the outer wall of the segmented magnetic sheets 3 and air gap sheets 4, the overall board area occupied by the resonant inductor is reduced, and the power density of the power board is increased. The use of square film-wound coil improves the space utilization of the coil 8, maximizes the reduction of the resonant inductor volume, and thus reduces the power supply space.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
