Description

Technical Field

[0001] The utility model relates to the field of electronic transformers, and particularly to a magnetic core structure of an electronic transformer. Background Art

[0002] The working principle of the magnetic core is to change the current by means of the magnetic flux under the circuit conditions to achieve the change of the output signal. When an electric current passes through the magnetic core winding, magnetic flux is generated inside the magnetic core, and this magnetic flux in turn generates electromagnetic induction, thereby changing the current, and thus achieving the change of the output signal. In a transformer, the magnetic core can increase the intensity and direction of the electrical signal, thereby converting the electrical signal into the required output value.

[0003] The utility model with the publication number CN219286181U discloses a transformer magnetic core, which includes an upper base and a lower base. The main body parts are respectively arranged in the middle of the upper base and the lower base, and the wing parts are respectively arranged on both sides of the upper base and the lower base. A protrusion is arranged around the main body part of the upper base, and a groove matching the protrusion is arranged on the main body part of the lower base.

[0004] In the transformer magnetic core in the above technical solution, when the coil is wound around the magnetic core, it cannot dissipate heat effectively when surrounded on all sides. The coil of the transformer needs to supply current and generates heat energy at the same time. The magnetic core structure of the transformer cannot dissipate heat effectively, so the temperature inside the transformer rises, and the overheating of the transformer temperature will cause the problem of reduced efficiency of the transformer.

[0019] Preferably, one side of the plurality of heat dissipation openings far from the base respectively penetrates through the side walls.

[0020] By adopting the above technical solution, while increasing the heat dissipation area of the end face of the coil, the heat dissipation performance of the wire core structure is improved.

[0021] The technical effects of the present utility model are mainly reflected in the following aspects:

[0022] 1. By providing a plurality of heat dissipation grooves on the winding post and making the heat dissipation grooves penetrate through the base, the heat dissipation area of the inner side face and the end face of the coil can be increased.

[0030] The following is a further detailed description of the present application in combination with the attached Figures 1-4 to make the technical solution of the present application easier to understand and master.

[0031] An embodiment of the present application discloses a magnetic core structure of an electronic transformer.

[0032] Referring to Figures 1-4 , a magnetic core structure of an electronic transformer in this embodiment includes a winding column 1. Two bases 2 are fixedly connected to the side surface of the winding column 1. The two bases 2 are arranged oppositely. Two side walls 3 are fixedly connected to the two bases 2 respectively. The side surfaces of the two side walls 3 close to the winding column 1 are arranged in an arc shape and are coaxial with the winding column 1.

[0033] Referring to Figures 1-4, a plurality of heat dissipation grooves 11 are formed on the winding column 1. The plurality of heat dissipation grooves 11 are evenly distributed along the circumferential direction of the winding column 1. The heat dissipation grooves 11 penetrate from one end in the axial direction of the winding column 1 to the other end in the axial direction. The plurality of heat dissipation grooves 11 respectively penetrate through the base 2. By providing a plurality of heat dissipation grooves 11 on the winding column 1 and making the heat dissipation grooves 11 penetrate through the base 2, the heat dissipation area of the inner side and the end face of the coil can be increased. When the coil is wound around the winding column 1, the inner side and the end face of the coil can dissipate heat through the heat dissipation grooves 11, so as to improve the heat dissipation performance of the wire core structure.

[0034] Refer to Figures 1-4 , the joints between the plurality of heat dissipation grooves 11 and the winding column 1 are respectively in smooth transition with rounded corners. The sharp edges at the joints between the heat dissipation grooves 11 and the winding column 1 are removed to improve safety. When the coil is wound around the winding column 1, the possibility of damaging the coil at the joints between the heat dissipation grooves 11 and the winding column 1 is reduced.

[0035] Refer to Figures 1-4 , the sides of the two bases 2 close to the winding column 1 are arranged in a gradually expanding shape from the side close to the winding column 1 to the side far from the winding column 1. A plurality of heat dissipation through holes 21 are respectively formed on the two bases 2. The plurality of heat dissipation through holes 21 are evenly distributed around the central axis of the winding column 1. One end of the plurality of heat dissipation grooves 11 close to the winding column 1 is arranged in a gradually expanding shape to the end far from the winding column 1. By providing a plurality of heat dissipation through holes 21 on the base 2, the heat dissipation area of the end face of the coil can be increased. When the coil is wound around the winding column 1, the end face of the coil can dissipate heat through the heat dissipation through holes 21, so as to improve the heat dissipation performance of the wire core structure.

[0036] Refer to Figures 1-4 , a plurality of heat dissipation openings 31 are respectively formed on the two side walls 3. The plurality of heat dissipation openings 31 are evenly distributed along the length direction of the side walls 3. The sides of the plurality of heat dissipation openings 31 far from the base 2 respectively penetrate through the side walls 3. The corners between the plurality of heat dissipation openings 31 close to the winding column 1 and the side face are in smooth transition with rounded corners to reduce the possibility of damaging the coil. By providing a plurality of heat dissipation openings 31 on the side walls 3, the heat dissipation area of the side face of the coil can be increased. When the coil is wound around the winding column 1, the side face of the coil can dissipate heat through the heat dissipation through holes 21, so as to improve the heat dissipation performance of the wire core structure.

[0037] Of course, the above are only typical examples of the present application. In addition, the present application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
