Abstract

The present invention discloses a heat dissipation composite cable. The heat dissipation composite cable comprises an external coating layer, the middle portion of the external coating layer is provided with a core wire installation cavity, four surfaces of the core wire installation cavity are respectively provided with more than one through hole, one heat exchange tube is arranged in one throughhole in a pass-through mode, the middle portion of each heat exchange tube is provided with one heat exchange channel, the two ends of the heat exchange channel are opened, one ends of the heat exchange tubes pass through the through holes and are extended out of the outer portion of the external coating layer, the inner side end of each heat exchange tubes is inserted into one gasbag ball, the gasbag balls are internally provided with spherical cavities, each gasbag ball is provided with one core wire hole in the same direction, the core wire holes between the gasbag balls at the adjacent sides are oppositely arranged, and the gasbag balls on the same line pass through one cable. The heat dissipation composite cable performs one-by-one segmentation of the cables without mutually influence between the cables, and employs the external motoricity to allow a metal ball to perform reciprocating rolling in a heat dissipation channel so as to effectively exchange of the heat and the outsideand have good crush resistance and heat dissipation effects.

Description

technical field

[0001] The invention relates to the field of cables, in particular to a heat dissipation composite cable. Background technique

[0002] In the prior art, the cable includes an outer layer and more than one strand of cable core wires inside, and the inside of the outer layer is a space that is connected to each other. Therefore, when a fire occurs in one of the cables, or one of the cables When local heat is generated, the cables will affect each other, which will lead to the damage of the entire cable, which has a safety impact.

[0003] Furthermore, since the inside of the outer layer is a closed space, it cannot exchange heat with the external environment. When under pressure, the inner core wire is directly damaged by pressure, so the compression resistance and heat dissipation performance are relatively poor, and the service life Cables that are not long enough, especially when they are in motion, will greatly increase their chances of being crushed.

Embodiment Construction

[0019] Such as figure 1 and figure 2 As shown, the heat dissipation composite cable includes an outer coating layer 9, a core wire installation cavity 4 is provided in the middle of the outer coating layer 9, and more than one through hole is respectively opened on the four sides of the core wire installation cavity 4, and each through hole is passed through. The holes are all loaded into a heat exchange tube 3, and there is a heat exchange channel 11 in the middle of the heat exchange tube 3, both ends of the heat exchange channel 11 are open, and one end of the heat exchange tube 3 protrudes from the outer layer through the through hole. 9, the inner end of the heat exchange tube 3 is inserted into an airbag ball 2, and a spherical cavity 8 is arranged in the airbag ball 2, and a metal ball 7 is arranged in the heat exchange channel 11 inside the heat exchange tube 3 ;

[0020] Each airbag ball 2 is provided with a core wire hole 12 in the same direction, and the core wir...
