Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation cables in cable technology, in particular to a heat dissipation cable for equipment. Background Art

[0002] In the prior art, cables for equipment, especially cables used in large equipment, will generate a lot of heat during actual use. If the heat is accumulated and not easily dissipated, it will seriously affect the working efficiency and quality of the cable, and sometimes it will also affect the shielding effect of the cable, causing many problems. Therefore, there are many technical solutions for heat dissipation cables in the prior art.

[0003] For example: "A heat dissipation charging cable" disclosed in the publication (announcement) number: CN106887283A; includes a number of wires, an insulating bracket and an outer sheath. A number of wires are fixed on the insulating brackets respectively. A number of wires and insulating brackets are coated in the outer sheath, and insulating thermal oil is filled between a number of wires, insulating brackets and the outer sheath to form a heat dissipation insulating oil layer, and the wires are directly immersed in the insulating thermal oil. The heat dissipation charging cable of the present invention uses an insulating bracket to fix the wires so that the wires are directly immersed in the insulating thermal oil. During the charging process of the cable, the heat generated by the wire core is transferred to the insulating thermal oil layer through the wire insulation layer and absorbed by the insulating thermal oil, and then quickly dissipated into the surrounding air through the outer sheath, which can quickly reduce the conductor temperature and keep the cable in a low temperature working state, which increases the service life of the cable. In addition, no filling is used in the middle of the cable, which makes the entire cable easier to bend and more convenient to use.

[0004] For example: "A liquid cooling cable" disclosed in the publication (announcement) number: CN118366719A; including an insulating jacket, a plurality of signal transmission lines, a plurality of power lines, a PE cable, an oil supply pipe and at least two liquid cooling spiral metal transmission copper cable structures, a plurality of signal transmission lines, a plurality of power lines, a PE cable, an oil supply pipe and at least two liquid cooling spiral metal transmission copper cable structures are all arranged in the insulating jacket, at least two liquid cooling spiral metal transmission copper cable structures are arranged in the insulating jacket and used for signal transmission and heat dissipation, and the oil supply pipe is used to supply liquid cooling oil to the liquid cooling spiral metal transmission copper cable structure. The present invention has the advantages of good heat dissipation effect, can reduce heat generation, longer overall service life, and higher safety.

[0005] In the above-mentioned cable technical solutions and existing cable technical solutions, the heat dissipation cables are usually designed to achieve heat dissipation by introducing a liquid used for heat reduction and heat dissipation as a medium inside the cable, such as introducing heat transfer oil or coolant; however, the introduction of the liquid mainly used as a medium in this technical solution is relatively difficult. On the one hand, it is necessary to set up a space inside the cable to store these liquids, and on the other hand, it is necessary to maintain the sealing of these liquids, and the production of the entire cable is also relatively cumbersome.

[0006] In addition, in the above-mentioned cable technical solution, the interior of the cable is usually too full and the air inside the cable cannot breathe, which greatly reduces the heat dissipation effect. Heat accumulates in each layer structure and is difficult to dissipate.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a heat dissipation cable for equipment with a reasonable structure, ventilation function and good heat dissipation effect. Summary of the invention

[0014] Furthermore, the heat conducting plates on the inner heat dissipation layer and the heat conducting plates on the middle heat dissipation layer are installed in a staggered manner, and the heat conducting plates on the circumferential positions of the two layers are on the same diameter.

DETAILED DESCRIPTION

[0028] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] like Figure 1 As shown, a heat dissipation cable for equipment includes an internal cable core 1; a heat dissipation inner layer 2 is correspondingly arranged on the outside of the internal cable core 1, a heat dissipation middle layer 3 is arranged on the outside of the heat dissipation inner layer 2, and a heat dissipation outer layer 4 is correspondingly arranged on the outside of the heat dissipation middle layer 3; a wrapping layer 5 is correspondingly arranged on the outside of the heat dissipation outer layer 4, an outer shielding layer 6 is correspondingly arranged on the outside of the wrapping layer 5, and an outer sheath 7 is correspondingly arranged on the outside of the outer shielding layer 6;

[0030] like Figure 2 As shown, the heat dissipation inner layer 2 is coated on the internal cable core 1, and the outer wall of the heat dissipation inner layer 2 is also provided with divergent and evenly spaced heat conducting sheets 8, the heights of the heat conducting sheets 8 are consistent, and a ventilated area 9 is formed between adjacent heat conducting sheets 8; the heat dissipation middle layer 3 is coated and pressed on the heat conducting sheets 8, and the heat dissipation middle layer 3 correspondingly covers the ventilated area 9 of the heat dissipation inner layer 2 as a whole, and the heat generated by the internal cable core 1 is transferred to the heat dissipation middle layer 3 via the heat dissipation inner layer 2;

[0031] like Figure 3 and Figure 4 As shown, a heat-conducting sheet 8 is also provided on the outer wall of the heat-dissipating middle layer 3. The heat-conducting sheets 8 are arranged in a divergent shape with uniform intervals, and a breathable area 9 is provided between adjacent heat-conducting sheets 8; the heat-dissipating outer layer 4 is correspondingly covered and pressed on the heat-conducting sheet 8 of the heat-dissipating middle layer 3, and the breathable area 9 is covered as a whole. The heat of the heat-dissipating middle layer 3 is transferred to the heat-dissipating outer layer 4 through the heat-conducting sheet 8, and the outer wall of the heat-dissipating outer layer 4 is correspondingly covered by the wrapping layer 5. The heat on the heat-dissipating outer layer 4 passes through the wrapping layer 5, the outer shielding layer 6 and the outer sheath 7 to dissipate into the external environment.

[0032] The heat dissipation inner layer 2, the heat dissipation middle layer 3, the heat dissipation outer layer 4 and the heat conductive sheet 8 are all made of aluminum material; ten heat conductive sheets 8 are evenly spaced on the outer wall of the heat dissipation inner layer 2 and the outer wall of the heat dissipation middle layer 3.

[0033] The heat conducting plates 8 on the heat dissipation inner layer 2 and the heat conducting plates 8 on the heat dissipation middle layer 3 are installed in a staggered manner, and the heat conducting plates 8 on the two circumferential positions are on the same diameter.

[0034] The height of the heat conducting sheet 8 on the heat dissipation inner layer 2 is consistent with that of the heat conducting sheet 8 on the heat dissipation middle layer 3 , so that the height of the air permeable area 9 on the heat dissipation inner layer 2 is consistent with that of the air permeable area 9 on the heat dissipation middle layer 3 .

[0035] The internal cable core 1 includes a conductor 101 arranged in the middle, an insulating layer 102 covering the outside of the conductor 101, an inner shielding layer 103 covering the outside of the insulating layer 102, and an inner sheath 104 covering the outside of the inner shielding layer 103; the heat dissipation inner layer 2 is correspondingly covered on the outside of the inner sheath 104.

[0036] The inner shielding layer 103 and the outer shielding layer 6 are both copper wire braided layers; the inner sheath 104 and the outer sheath 7 are both made of epoxy resin material.

[0037] When the technical solution of the device is in specific operation, the internal cable core inside the cable is in the structure of the existing conductor, insulation layer, inner shielding layer and inner sheath; and the outside of the inner sheath is provided with a heat dissipation inner layer. When the internal cable core generates heat during operation, the heat will gradually be transferred to the heat dissipation inner layer. The heat dissipation inner layer, heat dissipation middle layer, heat dissipation outer layer and thermal conductive sheet are all made of aluminum and are easy to conduct heat.

[0038] After the heat is guided to the inner heat dissipation layer, the heat follows the position of the heat conductive sheet and transfers the heat to the middle heat dissipation layer. The middle heat dissipation layer is also provided with a heat conductive sheet, so the heat is transferred to the outer heat dissipation layer through the heat conductive sheet. The outside of the outer heat dissipation layer is only provided with a wrapping layer, an outer shielding layer and an outer sheath, so the heat can be dissipated more easily.

[0039] And in the process of heat dissipation of the three heat dissipation layers, breathable areas are set in the heat dissipation inner layer and the heat dissipation middle layer through the heat conductive sheet. The heat conductive sheet transfers the heat in sequence and also dissipates the heat in the breathable area. The heat is stored in the breathable area. The heat generated by the internal cable core is also stored in the breathable area to prevent the internal cable core from being affected by excessively high temperature. And this area is a transparent breathable area, which is convenient for heat exchange of the air in the breathable area, and the heat is evenly distributed and easier to dissipate.

[0040] The height and number of the heat conducting plates on the inner and middle heat dissipation layers are the same, but the position settings are different. The heat conducting plates on the two circles are staggered, which makes the heat conduction smoother and more reasonable, and speeds up the heat conduction.

[0041] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
