The invention provides a power cable with groove-type heat radiation performance, comprising a power cable. The power cable is characterized in that a power cable body comprises a plurality of power cable cores, a cable core heat conducting layer, an electromagnetic shielding layer, cable heat radiation rings, a plurality of cable radiating tubes, and a power cable protective housing from inside out in sequence. Each power cable core is insulated to each other. The cable core heat conducting layer is arranged among the power cable cores. The electromagnetic shielding layer wraps an integrated body formed by each power cable core and the cable core heat conducting layer. The cable heat radiation rings are arranged on the periphery of the electromagnetic shielding layer. Each cable radiating tube is arranged in the cable heat radiation ring. The power cable protective housing is arranged on the outermost periphery. The power cable protective housing of the power cable is provided with a heat conducting layer, and the heat conducting layer can transfer heat generated by the cable core of the power cable in time, and the heat is radiated to the external through the heat radiation rings and the radiating tubes in the power cable.
Description
technical field [0001] The invention relates to the technical field of power cable heat dissipation, in particular to a power cable with grooved heat dissipation performance. Background technique [0002] Power cooling is usually a heat sink for high-power electronic components. There is no external power supply and natural cooling. Most of them are made of aluminum alloy profiles, which are cut into required sizes according to the size of components, such as high-power switching tubes or triodes. heat sink. Of course, under special circumstances, super-high-power electronic components also have cooling fans. For example, the switching tube of a switching power supply must be equipped with a cooling fan. [0003] Power cable (power cable), a cable used to transmit and distribute electrical energy. It is often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines...
