[0022] ​In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present application, therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment.

[0024] Embodiment

[0025] Reference Figures 1 to 6 For the embodiment of the present application, the embodiment provides a pressure-resistant cylindrical inductor framework, comprising a winding outer cylinder 101 and a support 104 arranged on the winding outer cylinder 101, the inner wall of the heat dissipation cavity 101a of the winding outer cylinder 101 is connected with one end of a plurality of uniformly distributed fins 102, and the other end of the fin 102 is connected with the outer surface of the inner cylinder 103 located in the heat dissipation cavity 101a;

[0026] In the embodiment, one end of the fin 102 is a first support end 102-1, the other end of the fin 102 is a second support end 102-2, the first support end 102-1 of the fin 102 is connected with the inner wall of the heat dissipation cavity 101a, and the second support end 102-2 of the fin 102 is connected with the outer surface of the inner cylinder 103;

[0027] Different from the traditional cylindrical inductor framework, a plurality of fins and an inner cylinder are arranged at the winding cylinder heat dissipation cavity at the winding copper wire, and the thickness of the winding cylinder is reduced;

[0028] Specifically, the inner wall of the heat dissipation cavity 101a of the winding outer cylinder 101 is uniformly provided with a plurality of fins 102, and the other end of the fin 102 is connected with the outer surface of the inner cylinder 103 located in the heat dissipation cavity 101a. This improves the mechanical strength of the winding outer cylinder 101, so that the thickness of the winding outer cylinder 101 can be reduced. Secondly, the inner wall of the thin winding outer cylinder 101, the surface of the fin 102 and the outer surface of the inner cylinder 103 all improve the heat dissipation surface area, so that the improved cylindrical inductor framework has better heat dissipation effect;

[0029] As shown in the example, Figure 2 , Figure 4 As shown, the adjacent fins 102 have a heat dissipation channel 102a, a reasonable number of fins 102 are arranged to be spaced apart, forming a relatively spacious heat dissipation channel 102a, so that it has good heat transfer;

[0030] For example, as shown in FIG. 1, the fin 102 is formed by a plurality of fin bodies 102a, and the fin bodies 102a are arranged in parallel to each other, and the fin bodies 102a are arranged in parallel to the longitudinal direction of the winding outer cylinder 101. Figure 6 As shown, the outer end 102-4 of the fin 102 is at an acute angle with the first support end 102-1 and at an obtuse angle with the second support end 102-2, so as to expand the aperture of the tapered port 101a-1 at both ends of the heat dissipation cavity 101a, which can increase the capacity of air entering the heat dissipation cavity 101 of the winding outer cylinder 101, so that the air can be in more sufficient contact with the fin 102, and the heat exchange efficiency is improved.

[0031] For example, as shown in FIG. 1, the fin 102 is formed by a plurality of fin bodies 102a, and the fin bodies 102a are arranged in parallel to each other, and the fin bodies 102a are arranged in parallel to the longitudinal direction of the winding outer cylinder 101. Figure 5 As shown, the two side surfaces 102-3 of the fin 102 are concave at the middle part of the fin 102, and the side surfaces of the fin 102 are symmetrically concave to the middle part of the fin, which can increase the surface area of the fin, and meanwhile does not affect the mechanical structure of the fin, and also can reduce the weight of the inductor skeleton, and more importantly, improves the volume of the heat dissipation channel 102a of the adjacent fin, which improves the heat dissipation efficiency and also improves the heat exchange efficiency.
