Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic cores, in particular to a magnetic core structure with good heat dissipation. Background Art
[0002] Magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices.
[0003] As a key component for storing and processing electromagnetic signals, the performance and application requirements of the magnetic core are constantly improving. However, the magnetic core will generate a lot of heat during operation. If the heat cannot be dissipated in time and effectively, the core temperature will be too high, affecting its stability and reliability, and even shortening its service life. Therefore, a magnetic core structure with good heat dissipation is proposed. Utility Model Content
[0004] The purpose of the utility model is to provide a magnetic core structure with good heat dissipation to solve the problems raised in the above background technology.
[0005] To achieve the above object, the utility model provides the following technical solutions: a magnetic core structure with good heat dissipation, comprising a magnetic core body, wherein first vents are provided on both upper and lower sides of the magnetic core body, and a plurality of second vents are provided on the outer side of the magnetic core body, wherein the first vents and the second vents are used for heat dissipation inside the magnetic core body, and an external component is provided on one side of the magnetic core body;
[0006] The external connection component includes a connecting column and an annular plate. A limiting groove is provided on one side of the annular plate. A connecting frame is fixed to one end of the connecting column. The limiting plate is fixed to the outside of the connecting frame. A plurality of fins are fixed to the outside of the connecting frame.
[0007] Preferably, a heat dissipation cavity is provided inside the magnetic core body, and the first vent hole and the second vent hole are both connected to the heat dissipation cavity.
[0008] Preferably, the outer side of the annular plate is fixed to the inner side wall of the heat dissipation cavity, and the shape of the annular plate is circular.
[0009] Preferably, a limiting hole is provided on the outer side of the magnetic core body, and one side of the limiting hole is connected to the heat dissipation cavity.
[0010] Preferably, an internal thread is arranged on the inner wall side of the limiting hole, and a thread is arranged on the outer side of the connecting column.
[0011] Preferably, one end of the connecting column is inserted into the inner side of the limiting groove, and the outer side of the limiting hole is sleeved on the outer side of the connecting column.
[0012] Preferably, the internal thread is connected to the threaded part.
[0013] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:
[0014] 1. By arranging a plurality of first ventilation holes and second ventilation holes on the outside of the magnetic core body, the heat dissipation area of the magnetic core body is increased, so that external cold air can enter the inner side of the heat dissipation cavity more fully and quickly, and quickly take away the heat generated inside the magnetic core body. Timely heat dissipation can effectively prevent the magnetic core body from being overheated during operation, thereby ensuring the stability and reliability of the magnetic core body and extending the service life of the magnetic core body.
[0015] 2. Connect the external component to one side of the core body so that the internal thread and the screw thread are connected. At this time, the connecting column is inserted into the inner side of the limiting groove. The heat generated by the core body during operation is transmitted to the fins through the connecting column. The external air flows through the fins to take away the heat. The fins have a large heat dissipation area and can increase the contact area with the external air, thereby more effectively dissipating the heat into the air, enhancing the heat dissipation effect of the core. It is particularly suitable for work in high temperature environments. The limiting groove and the annular plate are connected so that the connecting column can be firmly inserted into the inner side of the limiting groove to ensure that the connection between the external component and the core body is stable and reliable and not easy to loosen or fall off. Through the heat dissipation effect of the external component, the core body can maintain a low temperature during operation, thereby avoiding performance degradation or failure risks caused by excessive temperature.

[0030] In order to speed up the heat dissipation of the magnetic core body 1, an external component 3 is provided, and the external component 3 includes a connecting column 34 and an annular plate 35. A limiting groove 36 is provided on one side of the annular plate 35, and a connecting frame 31 is fixed to one end of the connecting column 34. The connecting column 34 is inserted into the inner side of the limiting groove 36, and one end of the limiting groove 36 is attached to the inner side of the limiting groove 36 of the annular plate 35. At this time, the heat generated by the magnetic core body 1 during operation is transmitted to the fin 33 through the connecting column 34, and the external air flows through the fin 33 to take away the heat. A limiting plate 32 is fixed to the outer side of the connecting frame 31, and a plurality of fins are fixed to the outer side of the connecting frame 31. The outer side of the annular plate 35 is fixed to the inner wall of the heat dissipation cavity 4. The shape of the annular plate 35 is circular. A limiting hole 39 is provided on the outer side of the core body 1. One side of the limiting hole 39 is communicated with the heat dissipation cavity 4. The connecting column 34 is connected to the core body 1, so that the heat generated by the core body 1 during operation can be quickly transferred to the fin 33. The fin 33 has a large heat dissipation area, which can increase the contact area with the external air. Due to the heat dissipation effect of the external component 3, the core body 1 can maintain a low temperature during operation, thereby avoiding the performance degradation or failure risk caused by excessive temperature.
[0031] An internal thread 37 is provided on the inner wall side of the limiting hole 39, and a screw thread 38 is provided on the outer side of the connecting column 34. One end of the connecting column 34 is inserted into the inner side of the limiting groove 36, and the outer side of the limiting hole 39 is sleeved on the outer side of the connecting column 34. The connecting column 34 is passed through the inner side of the limiting hole 39, and then the limiting plate 32 and the connecting frame 31 are rotated so that the internal thread 37 and the screw thread 38 are threadedly connected. The internal thread 37 is threadedly connected with the screw thread 38, and the limiting groove 36 is connected to the annular plate 35, so that the connecting column 34 can be firmly inserted into the inner side of the limiting groove 36 to ensure that the connection between the external component 3 and the magnetic core body 1 is stable and reliable.
[0032] Working principle: when the magnetic core body 1 is in use, external air is blown to the inside of the heat dissipation cavity 4 through the first air vent 2 and the second air vent 5 to cool the inside of the magnetic core body 1. A plurality of first air vents 2 and second air vents 5 are arranged on the outside of the magnetic core body 1, so that the magnetic core body 1 can be cooled in time to avoid the magnetic core body 1 from being overheated during operation. The arrangement of the plurality of first air vents 2 and second air vents 5 increases the heat dissipation area of the magnetic core body 1, so that external cold air can enter the inside of the heat dissipation cavity 4 more fully and quickly, and exchange heat with the magnetic core body 1, thereby quickly taking away the heat generated inside the magnetic core body 1. Timely heat dissipation can effectively avoid the magnetic core body 1 from being overheated during operation, thereby ensuring the stability and reliability of the magnetic core body 1 and extending the service life of the magnetic core body 1.
[0033] The external component 3 is connected to one side of the core body 1. At this time, the connecting column 34 is passed through the inner side of the limiting hole 39, and then the limiting plate 32 and the connecting frame 31 are rotated so that the internal thread 37 and the screw thread 38 are threadedly connected. At this time, the connecting column 34 is inserted into the inner side of the limiting groove 36, and at the same time, one end of the limiting groove 36 is attached to the inner side of the limiting groove 36 of the annular plate 35. At this time, the heat generated by the core body 1 during operation is transmitted to the fin 33 through the connecting column 34, and the external air flows through the fin 33 to take away the heat, and is connected to the core body 1 through the connecting column 34, so that the heat generated by the core body 1 during operation can be quickly dissipated. The heat is transferred to the fins 33, which have a large heat dissipation area and can increase the contact area with the external air, so as to more effectively dissipate the heat into the air, thereby enhancing the heat dissipation effect of the magnetic core, and is particularly suitable for working in a high temperature environment. The limiting groove 36 and the annular plate 35 are connected, so that the connecting column 34 can be firmly inserted into the inner side of the limiting groove 36, ensuring that the connection between the external component 3 and the magnetic core body 1 is stable and reliable, and is not easy to loosen or fall off. Through the heat dissipation effect of the external component 3, the magnetic core body 1 can maintain a low temperature during operation, thereby avoiding the performance degradation or failure risk caused by excessive temperature.
