It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

The heat dissipation assembly 7 includes a heat dissipation ring 71 and a heat-absorbing plate 72. The heat dissipation ring 71 is fixedly connected to the heat-absorbing plate 72. The heat-absorbing plate 72 is located outside the protective layer 6, and the heat dissipation ring 71 is located inside the protective layer 6. The heat dissipation ring 71 is fixedly connected to the surface of the heat-absorbing layer 5, and the heat-absorbing plate 72 is embedded in the inner wall of the protective layer 6. Multiple heat dissipation assemblies 7 are provided on the surface of the protective layer 6, and the multiple heat dissipation assemblies 7 are evenly distributed on the surface of the protective layer 6.

[0025] The specific settings and effects of the embodiment will be described below. The plurality of first heat dissipation grooves 51 arranged on the inner wall of the heat absorption layer 5 improve the air flow outside the wire core 1, and then the heat absorption layer 5 absorbs the heat inside, and at the same time, the heat absorption layer 5 conducts the heat to the heat absorption plate 72, which continues to transfer outward through the heat absorption plate 72, and finally exchanges the heat inside the whole with the external environment through the heat dissipation ring 71, so as to realize the rapid heat dissipation inside the protection layer 6. First, the wire core 1 generates a large amount of heat during work, and the plurality of first heat dissipation grooves 51 arranged on the inner wall of the heat absorption layer 5 form micro ventilation pipes, which greatly improve the air flow outside the wire core 1 and accelerate the speed of heat carried away by the air. It is like opening a fan in a hot room to quickly dissipate heat. Then, the heat absorption layer 5 acts as a heat collector, efficiently absorbing the heat generated and dissipated by the wire core 1, avoiding excessive accumulation of heat in a local area. Subsequently, the heat absorption layer 5 conducts the absorbed heat to the heat absorption plate 72, which acts as a heat transfer station and further transfers the heat outward due to its good heat conduction performance. Finally, the heat dissipation ring 71, as the terminal of the whole heat dissipation system, fully exchanges the heat transferred from the inside with the external environment, realizing the rapid heat dissipation inside the protection layer 6. In this way, not only is the wire core 1 effectively protected to prevent it from overheating and accelerating aging and damage, but also the service life of the wire core 1 is prolonged, the insulation performance of the cable is ensured to be stable, the safety hidden danger caused by high temperature is reduced, and the stability and reliability of power transmission are improved.

[0027] The effect of the whole embodiment is that the two second heat dissipation grooves arranged on the surface of the heat dissipation ring 71 rapidly dissipate heat from the surface of the heat dissipation ring 71, and the plurality of heat dissipation holes in the second heat dissipation grooves accelerate the air flow on the surface of the heat dissipation ring 71, further improving the heating efficiency.

[0028] The use method and working principle of the device are as follows: the plurality of first heat dissipation grooves 51 arranged on the inner wall of the heat absorption layer 5 improve the air flow outside the wire core 1, and then the heat absorption layer 5 absorbs the heat inside, and at the same time, the heat absorption layer 5 conducts the heat to the heat absorption plate 72, which continues to transfer outward through the heat absorption plate 72, and finally exchanges the heat inside the whole with the external environment through the heat dissipation ring 71, so as to realize the rapid heat dissipation inside the protection layer 6.
