Abstract
Description
Technical Field
[0001] This utility model relates to the field of ferrite core technology, and specifically to a ferrite core that is easy to dissipate heat. Background Technology
[0002] Ferrite cores are high-frequency magnetic materials commonly used in transformers and other products. Their main functions are shielding electromagnetic noise, increasing permeability, and improving inductance. Existing ferrite cores, while shielding external electromagnetic noise by surrounding the coil, suffer from poor heat dissipation, relying solely on the exposed surface of the core for cooling. This makes it difficult for heat to dissipate during high-frequency operation, ultimately leading to increased overall transformer temperature and losses, directly reducing transformer efficiency. This results in poor performance and a less than ideal user experience in high-power transformers. Therefore, to avoid the shortcomings of existing technology, improvements are necessary. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a structurally stable ferrite core that is easy to dissipate heat.
[0004] This utility model is achieved through the following technical solution:
[0005] A heat-dissipating ferrite core includes a base plate, a magnetic column at the center of the base plate, a baffle on both the left and right sides of the base plate, a first heat dissipation channel on the inner side of the magnetic column, a plurality of heat dissipation holes communicating with the first heat dissipation channel on the outer side of the magnetic column, and a plurality of second heat dissipation channels on the baffle.
[0006] Furthermore, a slot is provided on both the front and rear sides of the base plate.
[0007] Furthermore, the slot is arranged in a semi-circular, U-shaped, or V-shaped manner.
[0008] Furthermore, the top of the magnetic column is provided with several upper heat dissipation grooves.
[0009] Furthermore, the side of the upper heat dissipation groove is provided with an upper inclined surface.
[0010] Furthermore, the bottom of the base plate is provided with a heat dissipation groove.
[0011] Furthermore, the side of the lower heat dissipation groove is provided with a downward slope.
[0012] Furthermore, the outer surface of the baffle is provided with a heat-conducting layer.
[0013] Furthermore, the first heat dissipation channel penetrates the ferrite core, and the second heat dissipation channel penetrates the ferrite core.
[0014] Furthermore, the base plate, magnetic column, and baffle are integrally formed, and a wire storage groove is formed between the magnetic column and the baffle.
[0015] Compared to existing technologies, this invention features a first heat dissipation channel on the inner side of the magnetic column, several heat dissipation holes on the outer side of the magnetic column communicating with the first heat dissipation channel, and a baffle with several second heat dissipation channels. During the operation of the ferrite core, air flows through the first and second heat dissipation channels, carrying away the heat inside the core. The heat dissipation holes are connected to the coil, carrying away the heat generated during the coil's operation, thus achieving heat dissipation from the core and improving its heat dissipation effect. The heat generated by the transformer during high-frequency operation is easily dissipated, reducing the overall temperature rise and losses of the transformer, improving its working efficiency, resulting in better performance and user experience for high-power transformers.

[0024] The top of the magnetic column 2 is provided with several upper heat dissipation grooves 8, which increases the heat dissipation area of the magnetic column 2, improves the heat dissipation effect of the magnetic column 2, and facilitates the sintering and forming of the magnetic column 2.
[0025] The upper heat dissipation groove 8 has an upper inclined surface 9 on its side, which facilitates demolding of the magnetic column 2 during molding.
[0026] The bottom of the base plate 1 is provided with a heat dissipation groove 10 to increase the heat dissipation area of the base plate 1, improve the heat dissipation effect of the base plate 1, and facilitate the sintering and molding of the base plate 1.

[0028] The outer surface of the baffle 3 is provided with a heat-conducting layer to accelerate the heat dissipation of the ferrite core and improve the heat dissipation effect of the ferrite core.
[0029] In practice, the first heat dissipation channel 4 and the second heat dissipation channel 6 penetrate the ferrite core, enhancing airflow and improving heat dissipation.
[0030] The base plate 1, magnetic column 2 and baffle 3 are integrally formed, making the structure of the ferrite core more stable. A wire storage groove 12 is formed between the magnetic column 2 and the baffle 3, which facilitates the storage of the coil.
