[0002] With the rapid development of electronic technology, especially in fields such as power electronics and electric vehicles, the demand for managing current and electromagnetic interference is increasing. Inductors, as important passive components, play a key role in these applications. The design and application of high-current shielded inductors have emerged to meet the performance requirements in high-current environments.

[0003] When carrying high currents, inductors are prone to overheating and increased losses, leading to reduced equipment efficiency and shortened lifespan. Therefore, inductors with excellent heat dissipation are particularly important.

[0004] Therefore, those skilled in the art provide a high current shielded inductor to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present invention is to provide a high-current shielded inductor to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A high-current shielded inductor comprises a housing and a base. The housing is fixedly mounted on the upper end surface of the base. A micro fan is rotatably mounted on the inner top wall of the housing. A plurality of through holes penetrating the top of the housing are provided in a circular array at the center of the upper end surface of the housing. Through slots 1, 2, 3, and 4 are respectively provided on the outer walls of the four sides of the housing near the lower end.

[0008] As a further solution of the present invention: the upper end surface of the base is provided with a slide groove 1, a slide groove 2, a slide groove 3 and a slide groove 4 near the inner walls of the four sides of the shell, and the slide grooves 1, 2, 3 and 4 are slidably connected with sliders 1, 2, 3 and 4 respectively.

[0009] As a further solution of the present invention: the upper end surfaces of the slider 1, slider 2, slider 3 and slider 4 are fixedly connected with baffle 1, baffle 2, baffle 3 and baffle 4 at a position close to the inner wall of the shell, and the baffle 1, baffle 2, baffle 3 and baffle 4 are respectively located in the through slot 1, through slot 2, through slot 3 and through slot 4, and are movably connected with the through slot 1, through slot 2, through slot 3 and through slot 4.

[0010] As a further solution of the present invention: the upper end surfaces of the slider one, slider two, slider three and slider four are fixedly connected with magnetic plates one, magnetic plates two, magnetic plates three and magnetic plates four respectively at positions away from the inner wall of the shell.

[0011] As a further solution of the present invention: a return spring 1, a return spring 2, a return spring 3 and a return spring 4 are respectively provided in the chute 1, the chute 2, the chute 3 and the chute 4.

[0012] As a further solution of the present invention: one end of the return spring 1, return spring 2, return spring 3 and return spring 4 are respectively fixedly connected to the inner walls of the slide groove 1, slide groove 2, slide groove 3 and slide groove 4, and the other end of the return spring 1, return spring 2, return spring 3 and return spring 4 are respectively fixedly connected to the slider 1, slider 2, slider 3 and slider 4.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When current passes through the inductor, a magnetic field is generated around it. This magnetic field can interact with the motor part of the micro fan to generate a force (the motor part of the micro fan is usually composed of a coil and a magnet. When current passes through the winding in the inductor, a magnetic field is generated around it. This magnetic field interacts with the magnetic field of the permanent magnet or electromagnet in the motor to generate electromagnetic force.), thereby driving the micro fan to rotate, thereby transferring heat through the through hole at the top of the shell. The magnetic field generated by the inductor after power is turned on can push the magnetic plate, thereby driving the slider to move, thereby pushing the baffle out of the slot, thereby forming an airflow channel, allowing air to circulate and take away heat. The reduction in temperature can significantly reduce the internal loss of the inductor, improve its working efficiency, and extend the service life of the inductor; in summary, the utility model can effectively solve the overheating and loss problems of large-current shielded inductors when carrying large currents, thereby improving their working performance and reliability.

The magnetic plate 1 25, the magnetic plate 2 26, the magnetic plate 3 27 and the magnetic plate 4 28 are fixedly connected, and the return spring 1 9, the return spring 2 10, the return spring 3 11 and the return spring 4 12 are respectively provided in the chute 1 5, the chute 2 6, the chute 3 7 and the chute 4 8.
