Description

Technical Field

[0001] The utility model relates to the technical field of magnetic cores, in particular to a high-efficiency heat dissipation hybrid magnetic circuit magnetic core. Background Art

[0002] Magnetic cores are mainly used to manufacture various inductive components, such as transformers, inductors, and filters. The existing magnetic cores are mainly of E-type and Japanese-type structures. When the produced magnetic cores are in use, coils need to be wound around the magnetic cores. By winding different numbers of coils, different functional effects can be achieved. However, the existing magnetic cores have certain deficiencies. Firstly, it is rather troublesome to wind the coils, thus reducing the production efficiency. Secondly, when the existing high-frequency transformer magnetic cores are in use, a large amount of heat will be generated at the contact place between the coils and the magnetic cores during use, and the temperature is relatively high. The high temperature will affect the lifespan of the magnetic cores and may also damage the surrounding electronic components. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-efficiency heat dissipation hybrid magnetic circuit magnetic core, which solves the problems of inconvenient wire winding and poor heat dissipation of the existing designed magnetic cores.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

A heat dissipation hole is opened in the center of the magnetic column. A plurality of slots are opened on the side surface of the magnetic column. Heat dissipation fins are arranged in the slots. Heat conduction blocks are arranged on the side plates. One end of the heat dissipation fin is in contact with the heat conduction block.

[0006] By adopting the above technical solutions: The magnetic core adopts a split structure of a magnetic column and side plates, which is convenient for winding coils. The heat conduction blocks are installed on the side plates and one end of the heat dissipation fin is in contact with the heat conduction block, so as to transfer the heat generated by the magnetic column and the side plates to the heat conduction block at the same time, reducing the working temperature of the magnetic core.

[0007] The slots are opened along the normal direction of the magnetic column.

[0008] By adopting the above technical solutions: The slots are opened along the normal direction of the outer surface of the magnetic column, so as to expand the heat absorption area of the heat dissipation fins inside the magnetic core and improve the heat dissipation effect.

[0009] Sliding grooves are opened on the side plates. One end of the side plate is provided with a slider part connected to the sliding groove. The sliding grooves correspond to the slots one by one.

[0010] By adopting the above technical solutions: The slider part is generally designed as a dovetail groove or a T-shaped groove. When the heat dissipation fins are inserted into the slots along the sliding grooves, the two side plates at both ends can be connected by the heat dissipation fins, and the installation is more rapid.

[0011] A groove is formed on the side plate, and a heat conduction hole communicating with the heat dissipation hole is formed on the groove. A heat conduction fin is inserted into the groove. An external thread is provided on the circumferential surface of the heat conduction block, and an internal thread engaging with the external thread is provided in the groove. One end of the heat conduction fin contacts the heat dissipation fin, and the other end contacts the heat conduction block.

[0012] By adopting the above technical solution: The groove is used to install the heat conduction fin, and the heat conduction fin is used to transfer the heat generated by the heat dissipation fin to the heat conduction block, improving the heat dissipation effect.

[0013] The heat conduction fin has a disc body and a sheet body. The sheet bodies are all connected to one side of the disc body. Insertion holes for the sheet bodies to be inserted are formed on the groove. Insertion slots for the sheet bodies to be inserted are formed at one end of the heat dissipation fin. The heat conduction block is screwed into the groove and abuts against the disc body.

[0014] By adopting the above technical solution: The heat conduction fin includes a disc body and a sheet body. The disc body is located in the groove, and the sheet bodies are inserted into the insertion slots on the heat dissipation fin through the insertion holes, thereby fixing the heat dissipation fins together. Through the threaded fixed connection between the heat conduction block and the groove, the stability of the magnetic core structure is ensured.

[0015] A hollow guide post is connected to the side of the side plate where the heat conduction hole faces the magnetic column, and one end of the guide post is inserted into the heat dissipation hole.

[0016] By adopting the above technical solution: A guide post is arranged on the heat conduction hole of the side plate, and the side plate is positioned by the combination of the guide post and the heat dissipation hole, improving the installation effect and ensuring the installation accuracy of the magnetic column and the two side plates.

[0017] The technical effects and advantages of the present utility model:

[0018] 1. In this solution, the magnetic core adopts a split structure of a magnetic column and a side plate, which is convenient for winding the coil. A heat conduction block is installed on the side plate, and one end of the heat dissipation fin contacts the heat conduction block, so as to transfer the heat generated by the magnetic column and the side plate to the heat conduction block at the same time, reducing the working temperature of the magnetic core.

[0019] 2. In this solution, the insertion slots are formed along the normal direction of the outer surface of the magnetic column, so as to expand the heat absorption area of the heat dissipation fins inside the magnetic core and improve the heat dissipation effect.

[0020] 3. In this solution, the slider part is generally designed as a dovetail groove or a T-slot. When the heat dissipation fin is inserted into the insertion slot along the sliding groove, the two side plates at both ends can be connected by the heat dissipation fin, making the assembly of the magnetic core faster.
