Breathing type cable with high heat dissipation performance

Abstract

The invention discloses a breathing-type cable with high heat dissipation performance, and belongs to the technical field of cables. A heat dissipation piece similar to a breathing mode is arranged on an outer sheath on the outer side of a cable body, an outer heat dissipation ball film is located on the outer surface of the outer sheath, and an inner heat absorption ball is located between the outer sheath and the cable body to absorb heat; the middle embedded pipe serves as a medium to realize heat transfer, and after the inner heat absorption ball absorbs enough heat, the magnetic control block in the hemispherical cover is triggered to trigger a magnetic field leakage action according to the heat, so that a magnetic repulsive action is formed on the magnetic block in the inner heat absorption ball, and the magnetic block is forced to move towards the direction close to the outer heat dissipation ball film; the inner heat absorption ball is forced to deform locally under the pulling action of the traction wire, the deformation is transmitted to the outer heat dissipation ball film, air flow is accelerated while the contact area with the outside is increased, remarkable and efficient heat dissipation can be achieved, automatic resetting can be achieved after heat dissipation, efficient dynamic auxiliary heat dissipation can be continuously achieved, and the cable is maintained in a good working temperature range.

Description

technical field [0001] The invention relates to the technical field of cables, more specifically, to a breathing type high heat dissipation cable. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, which have different definitions. [0003] Definition 1: A wire made of one or more mutually insulated conductors and an outer insulating layer to transmit power or information from one place to another. [0004] Definition 2: It is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center, and the entire outer wrap Has a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. [0005] The length of the service life of the cable depends on the quality of the cable and the environment in which the...
