Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a high-efficiency heat dissipation cable. Background Technology

[0002] Cables, as important media for circuit and signal transmission, are widely used in power equipment and internet communication equipment. A cable mainly consists of one or more conductors, their insulation layer, protective layer, and outer sheath. Traditional cables experience insulation aging and reduced transmission efficiency due to conductor heating during high-load operation. Existing heat dissipation solutions, such as adding heat sinks or air-cooled structures, have limitations. Adding heat sinks increases volume, while air cooling relies on external equipment.

[0003] Existing cables lack effective rapid heat dissipation structures. A search revealed that publication number CN201822179041.8 discloses a high-efficiency heat dissipation cable using an aluminum alloy frame. The aluminum alloy frame has an insulation layer on its outer side, and the aluminum alloy frame is located outside the insulation layer. The aluminum alloy frame has multiple arc-shaped protrusions, which can effectively conduct heat and dissipate heat. The arc-shaped protrusions further increase the heat dissipation area of ​​the cable. The solution has a good heat dissipation effect, but the manufacturing cost is high. At the same time, the aluminum alloy frame reduces the flexibility of the cable and makes it easy to damage the internal frame structure during use. Utility Model Content

[0004] The technical problem this invention aims to solve is that while increasing heat dissipation and strength through a high thermal conductivity frame results in high manufacturing costs, it also reduces circuit flexibility and poses a risk of damaging the internal frame structure during use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model proposes a high-efficiency heat dissipation cable, including a cable core and an outer sheath sleeved outside the cable core. A heat-conducting layer is filled between the cable core and the outer sheath. Slots are correspondingly opened on the outer sheath and the heat-conducting layer. Heat-conducting components are installed in the slots. The two ends of the heat-conducting components are located outside the outer sheath. Multiple sets of slots and heat-conducting components are equidistantly arranged along the length direction of the outer sheath.

[0006] Preferred technical solution 1: The outer surface of the outer sheath is provided with a spiral guide groove, which increases the surface area of ​​the cable.

[0007] Preferred technical solution 2: The cable core is provided with an inner insulating layer, a shielding layer and an outer insulating layer from the inside out, and the inner insulating layer and the outer insulating layer are made of PVC-based insulating material.

[0008] Preferred technical solution 3: The shielding layer consists of an inner aluminum foil layer and an outer copper wire braid.

[0009] Preferred technical solution four: The outer sheath has an elliptical cross-section and two sets of cable cores are symmetrically arranged inside. A support member is arranged between the two sets of cable cores, and multiple sets of support members are equidistantly arranged along the length of the outer sheath.

[0010] Preferred technical solution five: The thermally conductive layer is a silicone thermally conductive layer and is filled with graphene filler inside; the thermally conductive component is a copper or aluminum thermally conductive component.

[0011] The present invention proposes a high-efficiency heat dissipation cable, and the beneficial effects achieved by adopting the above structure are as follows:

[0012] (1) Achieving a dynamic balance between efficient heat dissipation and flexibility, breaking through the limitations of traditional rigid frames, slot-type discontinuous heat-conducting components, multiple sets of intermittent layouts, elliptical cross-section double cable cores + support spacing design, after the heat-conducting layer absorbs the heat of the cable core, it is directly conducted to the outside by the heat-conducting components (copper / aluminum) in the slot. The intermittent layout avoids the rigid constraints of the fully enclosed metal frame, and local reinforcement maintains overall flexibility. The support separates the double cable cores to prevent heat accumulation, and the elliptical cross-section optimizes stress distribution, so there is no risk of structural deformation when installing and bending.

[0013] (2) The spiral guide groove of the outer sheath increases the surface area by 40% and enhances the toughness of the cable. The heat-conducting layer is a silicone heat-conducting layer and is filled with graphene filler. It works with copper or aluminum heat-conducting components to accelerate the heat dissipation of the heat-conducting layer.

[0014] (3) The heat resistance of the modified PVC insulation layer is increased to 105℃, the thermal conductivity is improved, the aluminum foil shielding layer blocks high frequency interference, the copper wire braiding layer conducts heat simultaneously, the electromagnetic compatibility and heat dissipation meet the standards, the spacing is set with support components to resist external pressure, avoid the cable core deformation leading to the failure of the thermal conductive layer, and extend the service life.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] Example 1

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A high-efficiency heat dissipation cable includes a cable core 1 and an outer sheath 2 sleeved on the outside of the cable core 1. A heat-conducting layer 3 is filled between the cable core 1 and the outer sheath 2. Slots are correspondingly opened on the outer sheath 2 and the heat-conducting layer 3. Heat-conducting components 4 are installed in the slots. The two ends of the heat-conducting components 4 are located outside the outer sheath 2. The heat is absorbed by the cable core 1 through the heat-conducting layer 3, and the heat is quickly transferred to the outside through the heat-conducting components 4. Multiple sets of slots and heat-conducting components 4 are equidistantly arranged along the length of the outer sheath 2. The intermittent arrangement enhances the local strength of the cable while also having good flexibility, making it easy to install and use.

[0025] like Figure 1 As shown, the outer surface of the outer sheath 2 is provided with a spiral guide groove 5. The spiral guide groove 5 increases the surface area of ​​the cable by 30%-50%, allowing heat exchange with the air through more contact surfaces, while also enhancing the cable's toughness.

[0026] like Figure 4 As shown, the cable core 1 is provided with an inner insulating layer 6, a shielding layer 7, and an outer insulating layer 8 from the inside out. The inner insulating layer 6 and the outer insulating layer 8 are made of PVC-based insulating material with added trioctyl trimellitate to improve heat resistance and thermal conductivity. The shielding layer 7 consists of an inner aluminum foil layer and an outer copper wire braid. The aluminum foil reflects high-frequency interference, and the copper wire conducts heat.

[0027] Example 2

[0028] Based on Example 1, such as Figures 1-3 As shown, the outer sheath 2 has an elliptical cross-section and two sets of cable cores 1 are symmetrically arranged inside. A support member 9 is arranged between the two sets of cable cores 1. Multiple sets of support members 9 are arranged at equal intervals along the length of the outer sheath 2 to increase the overall strength of the cable and at the same time avoid the problem of concentrated heat dissipation caused by the two sets of cable cores 1 being too close together.

[0029] Preferred technical solution 5: The heat-conducting layer 3 is a silicone heat-conducting layer 3, and is filled with graphene filler inside. The heat-conducting component 4 is a copper or aluminum heat-conducting component 4, which accelerates the heat dissipation of the heat-conducting layer 3.

[0030] In practical use, check that the spiral guide groove 5 on the surface of the cable outer sheath 2 is free of physical damage, and that the exposed parts at both ends of the heat-conducting component 4 are clean and free of oxidation. When laying in a bent manner, use the local rigid support points provided by the intermittent heat-conducting component 4 to flexibly bend between the support points. Do not bend directly at the installation position of the heat-conducting component 4 to prevent deformation of the slot structure. When laying, ensure that the cable spacing is ≥50mm so that the exposed end of the heat-conducting component 4 is in full contact with the air, and use the spiral guide groove 5 to guide the airflow.

[0031] Heat dissipation operation principle: internal heat source → heat conduction layer, the heat of cable core 1 is absorbed by the graphene silicone heat conduction layer 3; heat conduction layer → external environment, the heat is directly conducted to the surface of the outer sheath 2 through the slot-type heat conduction component 4, the surface is forced to convection, the spiral guide groove 5 is used to increase the surface heat dissipation area, increase the toughness and strength of the outer sheath 2, the dual core heat isolation is separated by the elliptical cross section + support component 9 to prevent heat accumulation.
