[0020] The technical scheme of the present application will be further described below with reference to the accompanying drawings of the embodiments of the present application. The present application is not limited to the following specific embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0021] As shown in FIG. 1, a heat dissipation device for a transformer coil comprises a framework, a coil body 400, a connecting assembly and a heat dissipation assembly. Figs. 1-2 The framework comprises a bottom plate 100, an iron core 200 and a cover plate 300, the bottom plate 100 is arranged at one end of the iron core 200, the cover plate 300 is arranged at the other end of the iron core 200, the coil body 400 is wound on the iron core 200, and the connecting assembly is arranged on one side of the bottom plate 100 far away from the iron core 200.

[0022] Specifically, a plurality of lead holes are formed on the bottom plate 100, and the lead holes are equidistantly formed. The coil body 400 is made by winding the enameled wire on the core 200. The connecting assembly includes two lead pins 500, one of which is arranged on one side of the bottom plate 100, and the other of which is arranged on the other side of the bottom plate 100. One end of the enameled wire is welded on the core 200, and is connected to one of the lead pins 500 through a lead wire, and the other end is connected to the other lead pin 500 after passing through a lead hole. The cover plate 300 covers the outside of part of the coil body 400. The heat dissipation assembly is an insulating heat-conducting silica gel pad 600, which is partially attached to one side of the bottom plate 100, and the other part is attached to the two lead pins 500. The insulating heat-conducting silica gel pad 600 abuts against the external shell.

[0023] That is, by winding the coil body 400 on the core 200, a complete transformer is formed with the framework and the connecting assembly. In normal use, the transformer can be used by connecting the two lead pins 500 to the outside. Because the insulating heat-conducting silica gel pad 600 is used, part of it is attached to the side of the bottom plate 100 that contacts the outside, and the other part is attached to the side of the two lead pins 500 that contacts the outside, so that the temperature generated by the transformer can be directly conducted to the outside through the insulating silica gel pad with high thermal conductivity, and then the heat is conducted away through the air, so that the purpose of quickly reducing the temperature of the entire transformer can be achieved.

[0024] In one embodiment, the heat dissipation assembly includes heat dissipation fins 710, a heat dissipation channel 720, and a heat dissipation fan 730, the heat dissipation fins 710 are arranged on one side of the bottom plate 100, the heat dissipation channel 720 penetrates the bottom plate 100, the core 200 and the cover plate 300, and the heat dissipation fan 730 is arranged at one end of the heat dissipation channel 720. The caliber of the heat dissipation channel 720 gradually decreases from the end far away from the heat dissipation fan 730 to the end close to the heat dissipation fan 730.

[0025] That is, by winding the wire package body 400 on the iron core 200, the complete transformer is formed with the skeleton and the connecting assembly. In normal use, the whole transformer can be used by connecting with the outside through the two lead pins 500. Since the heat dissipation fins 710 are arranged on one side of the bottom plate 100, the contact area with air can be increased, and then the heat generated by the wire package body 400 is transmitted to the bottom plate 100, and then can be well conducted from the heat dissipation fins 710, and finally the heat is conducted away through the air. It is worth mentioning that by arranging the heat dissipation channel 720 and the heat dissipation fan 730, and the diameter of the heat dissipation channel 720 gradually decreases from the end far away from the heat dissipation fan 730 to the end close to the heat dissipation fan 730, therefore, when rapid heat dissipation is needed, since the heat generated by the wire package body 400 is conducted to the inside of the iron core 200 and to the bottom plate 100 and the cover plate 300, and then to the inside of the heat dissipation channel 720, by starting the heat dissipation fan 730, the air with heat will be blown away through the heat dissipation fan 730, and since the diameter of the heat dissipation channel 720 gradually decreases from the end far away from the heat dissipation fan 730 to the end close to the heat dissipation fan 730, therefore, in the process of air flow, a good acceleration effect can be achieved, and then the air with heat can be blown away faster, and the purpose of quickly reducing the temperature of the whole transformer can be achieved.

[0026] In summary, the above-mentioned embodiments are not the limiting embodiments of the present application, and any modification or equivalent deformation made by those skilled in the art on the basis of the essential content of the present application is within the technical scope of the present application.
