[0015] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See also Figures 1 to 4 As shown, the present embodiment involves an electric power cabinet that is easy to dissipate heat, including a cabinet body 1, a vertical plate 2 is provided on the back side of the cabinet body 1, a centrifugal fan 3 is provided between the vertical plate 2 and the cabinet body 1, and the air outlet of the centrifugal fan 3 is connected to an air duct 4 coiled between the cabinet body 1 and the vertical plate 2, and the other end of the air duct 4 is connected to the outside world. A heat conducting needle 5 is provided in the air duct 4, which passes through the back plate of the cabinet body 1 and extends into it, and a wire clamp 6 is provided at one end of the heat conducting needle 5. The wire clamp 6 is provided in the cabinet body 1, and an air inlet 7 matching the centrifugal fan is provided on the back plate of the cabinet body 1.

[0019] Furthermore, the distances between two adjacent heat conducting needles 5 in the same air duct 4 are equal.

[0020] Furthermore, the centrifugal fan 3 is arranged at a central position between the vertical plate 2 and the cabinet body 1; the side of the centrifugal fan 3 has two air outlets with an interval angle of 180 degrees.

[0021] In this embodiment, due to the arrangement of the heat-conducting needles 5 in the air duct 4, when the centrifugal fan 3 is turned on, the air flow can flow out from the air outlet end of the centrifugal fan 3, pass through the air duct 4, and finally be discharged from the outlet of the air duct 4. During this period, the air flow sweeps the heat-conducting needles 5, taking away the heat thereon, thereby achieving a rapid heat dissipation effect.

[0022] Among them, through the provision of the wire clamp 6, one is used to fix the cable, and the other can increase the contact area between the fixed cable and the wire clamp to quickly collect heat.
