Description

Technical Field

[0001] This utility model relates to the field of magnetic component heat dissipation, specifically a high-efficiency heat dissipation magnetic component. Background Technology

[0002] Magnets wound with coils typically constitute electromagnets or permanent magnet excitation systems, the working principle and structural design of which depend on the specific application (such as solenoid valves, motors, sensors, etc.).

[0003] Currently, the wound coil needs to be energized to be magnetic. When the current passes through the coil, heat is generated. However, because the coil is tightly wound on the magnetic element, only part of the outer side of the coil is exposed. The outer side of the coil is difficult to dissipate heat effectively. In addition, the inner side of the coil is tightly connected to the magnetic element and is wrapped by the outer coil, resulting in poor heat dissipation on the inner side of the coil. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a magnetic element with high-efficiency heat dissipation, so as to solve the technical problem that the outer side of the coil is only partially exposed, the outer side of the coil is difficult to dissipate heat effectively, and the inner side of the coil is tightly connected to the magnetic element and is wrapped by the outer coil, resulting in poor heat dissipation effect on the inner side of the coil.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat dissipation magnetic element, comprising a magnetic element body and support portions fixed at both ends of the magnetic element body, wherein a through groove is provided at the adjacent ends of the two support portions, a coil winding portion located in the through groove is provided at the center of the magnetic element body, and a first heat dissipation groove penetrating the coil winding portion is provided at both ends of the magnetic element body, and a coil body is wound and fixed on the coil winding portion, wherein a second heat dissipation groove is provided at the distant ends of the two support portions.

[0006] The present invention is further configured such that both of the support portions are Y-shaped structures, and the second heat dissipation groove is connected to the through groove.

[0007] The present invention is further configured such that both of the first heat dissipation grooves are disposed on the inner wall of the coil body, and a heat dissipation cavity is disposed between the first heat dissipation grooves and the coil body.

[0008] The present invention is further configured such that the inner walls of the two first heat dissipation slots are each fixed with a first support plate at equal intervals, and the plurality of first support plates are all at the same horizontal position as the magnetic component body.

[0009] The present invention is further configured such that the first support plate contacts the inner wall of the coil body and supports the coil body in the center of the heat dissipation cavity.

[0010] The present invention is further configured such that the inner walls of the two first heat dissipation slots are each fixed with a second support plate at equal intervals, and the second support plate is in contact with the inner wall of the coil body.

[0011] The present invention is further configured such that baffles are fixed at both ends of the second support plate, the baffles protruding from the outer wall of the coil body, and the side wall of the baffle in contact with the coil body is provided with an arc-shaped part.

[0012] In summary, the present invention has the following advantages: The present invention provides a second heat dissipation groove connected to the through groove on the support portion. The coil body is wound around the coil winding portion through the through groove. The second heat dissipation groove increases the contact between the outer wall of the coil body and the air, allowing the outer side of the coil body to dissipate heat effectively. Simultaneously, the heat dissipation cavity between the first heat dissipation groove and the coil body effectively dissipates heat from the inside of the coil body. The first support plate / second support plate fixed in the first heat dissipation groove effectively supports the center position of the coil body, and during the support process, the inner side of the coil body still has a cavity for heat dissipation. This allows the coil body to dissipate heat simultaneously and efficiently from both the inside and outside during the heating process. The baffle blocks the two sides of the coil body, preventing the coil body from shifting towards the sides of the magnetic element body. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] A high-efficiency heat dissipation magnetic component, such as Figure 1-4 As shown, it includes a magnetic element body 1 and support parts 2 fixed at both ends of the magnetic element body 1. Each of the two support parts 2 has a through groove 5 at the end that is close to each other. A coil winding part 7 is provided at the center of the magnetic element body 1 in the through groove 5. Each of the two ends of the magnetic element body 1 has a first heat dissipation groove 3 that passes through the coil winding part 7. A coil body 4 is wound and fixed on the coil winding part 7. Each of the two support parts 2 has a second heat dissipation groove 6 at the end that is far apart from each other.

[0021] Both support parts 2 are Y-shaped structures. The second heat dissipation groove 6 is connected to the through groove 5. Both first heat dissipation grooves 3 are set on the inner wall of the coil body 4. A heat dissipation cavity is set between the first heat dissipation groove 3 and the coil body 4. The coil body 4 is wound on the coil winding part 7 through the through groove 5. The second heat dissipation groove 6 increases the contact between the outer wall of the coil body 4 and the air, so that the outer side of the coil body 4 can dissipate heat fully.

[0022] Furthermore, the inner walls of the two first heat dissipation slots 3 are fixed with first support plates 8 at equal intervals. The multiple first support plates 8 are all at the same horizontal position as the magnetic component body 1. The first support plates 8 are in contact with the inner wall of the coil body 4 and support the coil body 4 in the center part that is suspended in the heat dissipation cavity.

[0023] The inner walls of the two first heat dissipation slots 3 are each fixed with a second support plate 9 at equal intervals. The second support plate 9 is in contact with the inner wall of the coil body 4. Both ends of the second support plate 9 are fixed with baffles 11. The baffles 11 are protruding from the outer wall of the coil body 4, and the side wall of the baffles 11 in contact with the coil body 4 is provided with an arc-shaped part 10. The heat dissipation cavity between the first heat dissipation slots 3 and the coil body 4 effectively dissipates heat from the inside of the coil body 4. The first support plate 8 / second support plate 9 fixed in the first heat dissipation slots 3 effectively supports the center position of the coil body 4, and during the support process, there is still a cavity for heat dissipation on the inner side of the coil body 4. This allows the coil body 4 to dissipate heat from the inside and outside simultaneously and efficiently during the process of being energized and heated. The baffles 11 block the two sides of the coil body 4, preventing the coil body 4 from shifting to the sides of the magnetic element body 1.

[0024] The working principle of this utility model is as follows: A second heat dissipation groove 6 connected to the through groove 5 is provided on the support part 2. The coil body 4 passes through the through groove 5 and is wound on the coil winding part 7. The second heat dissipation groove 6 increases the contact between the outer wall of the coil body 4 and the air, so that the outer side of the coil body 4 can dissipate heat fully. At the same time, the heat dissipation cavity provided between the first heat dissipation groove 3 and the coil body 4 effectively dissipates heat from the inside of the coil body 4. The first support plate 8 / second support plate 9 fixed in the first heat dissipation groove 3 effectively supports the center position of the coil body 4, and during the support process, there is still a cavity for heat dissipation on the inner side of the coil body 4. This allows the coil body 4 to dissipate heat from the inside and outside simultaneously and efficiently during the process of being energized and heated. The baffle 11 blocks the two sides of the coil body 4, preventing the coil body 4 from shifting to the two sides of the magnetic element body 1.
