Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically, to a cable which is beneficial to heat dissipation. Background Art

[0002] Cables are commonly used conductors in daily life, transmitting electricity or information from one place to another. At present, with the development of society, electricity consumption has increased, and the requirements for cables have become higher and higher.

[0003] When a certain load current passes through the cable, the insulated core will generate heat. As the load current increases, the cable surface temperature becomes higher. However, the existing cables have poor heat dissipation effect during use and lack a fast and effective heat dissipation structure. Long-term use can easily cause cable aging, posing a safety hazard to production and processing. Therefore, in response to the above problems, a cable that is conducive to heat dissipation is proposed. Utility Model Content

[0008] When using a cable that is conducive to heat dissipation of the present technical solution, by setting thermally conductive silicone, the thermally conductive silicone has good thermal conductivity and is combined with a heat pipe and a heat sink to improve the heat dissipation effect of the cable. At the same time, the thermally conductive silicone has certain adhesion properties and can increase the toughness of the cable. By setting expansion holes, when the cable temperature is high, the thermally conductive silicone will expand and compress the expansion holes so that the volume can be dispersed, so that the thermally conductive silicone will not excessively squeeze the outer sheath, thereby increasing the service life of the outer sheath.

[0009] Furthermore, there are three cable cores, which are evenly distributed in the heat dissipation pipe through a partition plate.

[0010] Furthermore, there are a plurality of expansion holes, which are evenly distributed in the thermally conductive silica gel through a partition plate.

[0011] Furthermore, a conductor, a foaming layer and an inorganic composite insulating layer are arranged inside the cable core, the foaming layer is arranged inside the inorganic composite insulating layer, and the conductor is inside the foaming layer.

[0012] Furthermore, the foaming layer is made of polystyrene, and the inorganic composite insulation layer is composed of a synthetic fluorphlogopite tape and a flame-retardant glass fiber tape.

[0013] Furthermore, an outer protective layer and a breathable heat dissipation layer are respectively arranged inside the outer sheath, and the breathable heat dissipation layer is arranged on the inner side of the outer protective layer. The outer protective layer is made of PVC material and has a thickness of 3 mm.

[0014] (3) Beneficial effects

[0016] 1. A cable that is conducive to heat dissipation is provided with thermally conductive silicone. The thermally conductive silicone has good thermal conductivity and is combined with a heat pipe and a heat sink to improve the heat dissipation effect of the cable.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the technical scheme in the specific implementation mode of the utility model is clearly and completely described below to further illustrate the utility model. Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0030] Example:

[0031] The following is combined with Figure 1-2 The utility model is described in further detail.

[0032] See also Figure 1-2 The utility model provides a technical solution: a cable that is conducive to heat dissipation, including an outer sheath 1, a cable core 2, a partition plate 3, a thermally conductive silicone 4 and a heat dissipation tube 5, the cable core 2, the partition plate 3, the thermally conductive silicone 4 and the heat dissipation tube 5 are all in the outer sheath 1, the cable core 2, the partition plate 3 and the thermally conductive silicone 4 are in the heat dissipation tube 5, the thermally conductive silicone 4 is filled between the partition plate 3 and the cable core 2, the gap between the heat dissipation tube 5 and the outer sheath 1 is filled with a PP rope 6, the internal gap of the PP rope 6 is provided with a heat sink 7, the thermally conductive silicone 4 is provided with an expansion hole 8, and the partition plate 3 is provided with a steel wire rope 301.

[0033] By adopting the above technical scheme, by setting the thermal conductive silicone 4, the thermal conductive silicone 4 has good thermal conductivity and is combined with the heat pipe 5 and the heat sink 7, the heat dissipation effect of the cable can be improved. At the same time, the thermal conductive silicone 4 has certain adhesion properties, which can increase the toughness of the cable. By setting the expansion hole 8, when the cable temperature is high, the thermal conductive silicone 4 will expand and compress the expansion hole 8, so that the volume can be dispersed, so that the thermal conductive silicone 4 will not over-extrude the outer sheath 1, and the service life of the outer sheath 1 can be increased.

[0034] See also Figure 1There are three cable cores 2, which are evenly distributed in the heat pipe 5 through the partition plate 3. There are multiple expansion holes 8, which are evenly distributed in the thermal conductive silicone 4 through the partition plate 3. A conductor 201, a foaming layer 202 and an inorganic composite insulating layer 203 are arranged inside the cable core 2. The foaming layer 202 is arranged inside the inorganic composite insulating layer 203. The conductor 201 is inside the foaming layer 202. The foaming layer 202 is made of polystyrene. The inorganic composite insulating layer 203 is composed of a synthetic fluorphlogopite tape and a flame-retardant glass fiber tape. An outer protective layer 101 and a breathable heat dissipation layer 102 are respectively arranged inside the outer sheath 1. The breathable heat dissipation layer 102 is arranged on the inner side of the outer protective layer 101. The outer protective layer 101 is made of PVC material with a thickness of 3 mm.

[0035] The working principle of the utility model is:

[0036] When in use, by providing the heat-conducting silica gel 4, and cooperating with the heat pipe 5, the heat sink 7 and the breathable heat-dissipating layer 102, the heat dissipation effect of the cable can be improved. At the same time, when the temperature of the cable is high, the heat-conducting silica gel 4 will expand to a certain extent, and a part of the volume of the heat-conducting silica gel 4 that is expanded and deformed will be dispersed by compressing the volume of the expansion hole 8, so that the heat-conducting silica gel 4 will not excessively squeeze the outer sheath 1 due to its own expansion, thereby increasing the service life of the outer sheath 1;

[0037] At the same time, the thermally conductive silica gel 4 has good thermal conductivity and certain adhesive properties, and can tightly bond the insulating core and the outer sheath 1 together, thereby increasing the toughness of the cable.
