Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, specifically to a high-strength parallel cable. Background Technology
[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors, and characterized by being internally energized and externally insulated. Cables can be used to transmit electrical (magnetic) energy and information, realizing the conversion of electromagnetic energy.
[0003] Application number CN201520600077.2 describes a high-strength signal cable for industrial equipment, including an outer sheath and other structures. This invention combines multiple twisted-pair signal lines within a single cable sheath for easier installation and identification. However, in practical use, the concentrated arrangement of the multiple twisted-pair signal lines leads to excessive heat buildup inside the outer sheath. Since this application lacks a proper heat dissipation structure, it is prone to malfunctions. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A high-strength parallel cable includes a transmission mechanism, the transmission mechanism including a sheath, a plurality of conductors extending laterally through the sheath, a plurality of heat dissipation cavities formed on the sheath, and a flow guide groove formed on the outside of the sheath.
[0007] By adopting the above technical solution, since each heat dissipation cavity is located between two adjacent wires, the airflow in the heat dissipation cavity will carry away the heat of the two adjacent wires. Since each wire is equipped with heat dissipation cavities on both sides, each wire will be subjected to twice the heat conduction speed. Then, in conjunction with the flow guide grooves on the surface of the sheath, a Venturi effect is formed with the heat dissipation cavity. The bending deformation of the cable generates a pumping effect, realizing a passive air cooling cycle, which further improves the heat dissipation effect of the wire and effectively reduces the product failure rate.
[0008] In a preferred embodiment, the present invention can be further configured such that: the sheath is composed of a heat-conducting layer, a radiation layer and a heat-insulating layer, the heat-insulating layer is sleeved on the outside of the radiation layer, the radiation layer is sleeved on the outside of the heat-conducting layer, the thickness of the heat-conducting layer is greater than the thickness of the heat-insulating layer, and the thickness of the heat-insulating layer is greater than the thickness of the radiation layer.
[0009] In a preferred embodiment, the present invention can be further configured such that the wires penetrate the heat-conducting layer laterally, and multiple wires are equally spaced and arranged in a ring.
[0010] In a preferred embodiment, the present invention can be further configured such that: multiple heat dissipation cavities are located inside the heat-conducting layer, the multiple heat dissipation cavities are equally spaced and arranged in a ring, the heat dissipation cavities are arranged alternately with the wires, and the heat dissipation cavities are set in a wavy shape.
[0011] In a preferred embodiment, the present invention can be further configured such that: the thermally conductive layer is a high thermal conductivity boron nitride modified silicone, the radiating layer is a corrugated copper foil, and the heat insulation layer is woven from basalt fibers.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0013] In this invention, since each heat dissipation cavity is located between two adjacent wires, the airflow within the heat dissipation cavity will carry away the heat from the two adjacent wires. Furthermore, each wire is equipped with heat dissipation cavities on both sides, so each wire will experience twice the heat dissipation speed. Then, in conjunction with the flow guide grooves on the sheath surface, a Venturi effect is formed with the heat dissipation cavity. Through the bending deformation of the cable, a pumping action is generated to achieve passive air cooling circulation, further improving the heat dissipation effect of the wires and effectively reducing the product failure rate.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0020] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0021] The following describes, with reference to the accompanying drawings, some embodiments of a high-strength parallel cable provided by this utility model. Example 1
[0022] Combination Figure 1-3 As shown, the present invention provides a high-strength parallel cable, including a transmission mechanism 100. The transmission mechanism 100 includes a sheath 110, a plurality of conductors 120 that pass through the sheath 110 laterally, a plurality of heat dissipation cavities 130 opened on the sheath 110, and a flow guide groove 140 opened on the outside of the sheath 110.
[0023] Furthermore, the sheath 110 is composed of a thermally conductive layer 111, a radiating layer 112, and a thermally insulating layer 113. The thermally insulating layer 113 is sleeved on the outside of the radiating layer 112, and the radiating layer 112 is sleeved on the outside of the thermally conductive layer 111. The thickness of the thermally conductive layer 111 is greater than the thickness of the thermally insulating layer 113, and the thickness of the thermally insulating layer 113 is greater than the thickness of the radiating layer 112. The "thermal conductive-radiating-thermal insulating" three-layer composite structure realizes a gradient heat dissipation system, which is beneficial to improving heat dissipation efficiency.
[0024] Furthermore, the wire 120 extends laterally through the heat-conducting layer 111. Multiple wires 120 are evenly spaced and arranged in a ring. The layout design of multiple wires 120 ensures that the wires 120 do not get close to each other, thus avoiding heat accumulation and facilitating heat dissipation. Example 2
[0025] Combination Figure 1-3 As shown, based on Embodiment 1, multiple heat dissipation cavities 130 are located inside the heat-conducting layer 111. The multiple heat dissipation cavities 130 are equally spaced and arranged in a ring. The heat dissipation cavities 130 are arranged alternately with the wires 120. The heat dissipation cavities 130 are set in a wave shape. The layout design of the heat dissipation cavities 130 ensures that each wire 120 can be affected by the cooling effect of two heat dissipation cavities 130, thereby improving the heat dissipation effect of the wires 120. Example 3
[0026] Combination Figure 1-3 As shown, in the above embodiment, the thermally conductive layer 111 is a high thermal conductivity boron nitride modified silicone, the radiation layer 112 is a corrugated copper foil, and the heat insulation layer 113 is woven from basalt fiber. The high thermal conductivity boron nitride modified silicone (thermal conductivity greater than or equal to 5W / mk) has good thermal conductivity and good heat conduction effect. The corrugated copper foil increases the thermal contact surface and also has good anti-radiation performance, ensuring that the product can work stably. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material with mature and excellent heat insulation ability, improving the adaptability of the product in the external environment.
[0027] The working principle and usage process of this utility model: When this device is put into actual use, since each heat dissipation cavity 130 is located between two adjacent wires 120, the air flow in the heat dissipation cavity 130 will carry away the heat of the two adjacent wires 120. Since each wire 120 is equipped with heat dissipation cavities 130 on both sides, each wire 120 will be subjected to twice the heat conduction speed. Then, in conjunction with the flow guide groove 140 on the surface of the sheath 110, a Venturi effect is formed with the heat dissipation cavity 130. The bending deformation of the cable generates a pumping effect, realizing a passive air cooling cycle, which further improves the heat dissipation effect of the wires 120 and effectively reduces the product failure rate.
[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
