Description

Technical Field

[0001] The present application relates to the technical field of power transmission cables, and in particular to a heat dissipation wire and cable installed with an anti-break joint for aluminum-clad steel core aluminum stranded wire. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of conductors. Among them, aluminum-clad steel-core aluminum stranded wire is a type of conductor for cables, which has the advantages of good corrosion resistance and long service life.

[0003] Some existing cables are mainly composed of conductors, protective films and water-cooling pipes, wherein the water-cooling pipes are located at the center of several conductors, while the protective films are located at the outside of several conductors. During the use of the cables, a circulating water device is used to make cooling water flow in the water-cooling pipes, thereby absorbing the heat generated by the conductors, avoiding aging of the cables due to being in a high temperature state for too long, thereby increasing the service life of the cables.

[0004] However, in the above process, since the water cooling pipe is located at the center of the conductor, the contact area between the wall of the water cooling pipe and the conductor is small, resulting in a low heat dissipation effect on the conductor, thereby affecting the service life of the cable. Summary of the invention

[0005] The present application proposes a heat dissipation wire and cable installed with an aluminum-clad steel core aluminum stranded wire and an anti-break joint, which has the advantage of improving the heat dissipation effect of the conductor and is used to solve the problem that the contact area between the conductor and the water cooling pipe is small, resulting in a shortened service life of the cable.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a heat dissipation wire and cable installed with an anti-breaking joint for an aluminum-clad steel core aluminum stranded wire, comprising: a connecting end, the number of the connecting ends is two, the sides of the two connecting ends opposite to each other are fixedly installed with electrode joints, a wire is arranged between the two connecting ends, the wire is fixedly connected with the corresponding electrode joint, an electrode plate is fixedly installed on the side of the electrode joint opposite to the corresponding connecting end, and an electrode connection hole is opened inside the electrode plate for connecting power generation equipment or power consumption equipment;

[0007] A heat-conducting film is sleeved on the outer side of the wire, and the two ends of the heat-conducting film are respectively fixedly and sealedly connected to the connecting ends in corresponding directions. A protective film is sleeved on the outer side of the heat-conducting film, and the two sides of the protective film are respectively fixedly and sealedly connected to the connecting ends in corresponding directions. The space between the protective film and the heat-conducting film is a heat dissipation channel. Water distribution cavities are provided inside the two connecting ends, and the two water distribution cavities are connected through the heat dissipation channel. A water inlet hole is provided inside one of the connecting ends, and the water inlet hole connects the corresponding water distribution cavity with the external environment. A water outlet hole is provided inside the other connecting end, and the water outlet hole connects the corresponding water distribution cavity with the external environment.

[0008] Furthermore, the space between adjacent wires and the space between the wires and the thermally conductive film are filled with thermally conductive carbon fiber bundles.

[0009] Furthermore, support sheets are equidistantly arranged in the circumferential direction of the heat dissipation channel, and the support sheets are made of elastic material.

[0010] Furthermore, the support sheet is an arc-shaped structure, so that the support sheet can bend and deform when subjected to force.

[0011] Furthermore, the support sheet is made of elastic heat-conductive material.

[0012] Furthermore, the outer side of the support sheet is fixedly connected to the inner side of the protective film, and the inner side of the support sheet is fixedly connected to the outer side of the thermal conductive film.

[0013] Furthermore, a spring is sleeved on the outer side of the heat-conducting film, a sliding hole is opened inside the supporting sheet, the spring passes through the sliding hole, and the sliding hole forms a sliding contact with the spring.

[0014] Furthermore, the distance between the spring and the heat-conducting film is smaller than the distance between the spring and the protective film, the outer side of the support sheet is fixedly sealed to the inner side of the protective film, and the inner side of the support sheet is fixedly sealed to the outer side of the heat-conducting film.

[0015] This application has the following beneficial effects:

[0016] The present application provides a heat dissipation wire and cable installed with an anti-breakage joint for an aluminum-clad steel core aluminum stranded wire. Through the arrangement of a conductor, a heat-conductive carbon fiber bundle, a heat-conductive film and a protective film, a heat dissipation channel composed of the heat-conductive film and the protective film surrounds the outside of the conductor, and the excess space between the heat-conductive film and the conductor is filled with a heat-conductive carbon fiber bundle, so that the heat generated by the conductor can be transferred to the cooling water in the heat dissipation channel directly through contact with the heat-conductive film, and can also be indirectly transferred to the cooling water in the heat dissipation channel through the heat-conductive carbon fiber bundle and the heat-conductive film. Through the above-mentioned actions, the heat dissipation effect of the conductor is improved.

[0017] By arranging the thermally conductive film, the protective film and the supporting sheet, the supporting sheet is used to prop up the heat dissipation channel composed of the thermally conductive film and the protective film, so that an elastic buffer exists between the protective film and the wire. When external pressure is applied to the cable, the elastic buffer offsets part of the pressure to a certain extent, thereby reducing the probability of cable damage. At the same time, since the supporting sheet is fixedly connected to the thermally conductive film, the contact area between the thermally conductive film and the cooling water in the heat dissipation channel is indirectly increased, thereby improving the heat dissipation effect of the wire.

[0018] By setting the support sheet and the spring, the support sheet and the spring can play a certain limiting role on the cable. When the cable tends to bend at a certain position, the bending force will be blocked by the support sheet and the spring, thereby reducing the probability of bending at a certain position of the cable and making the cable less likely to be damaged.

[0019] Through the arrangement of the support sheet and the spring, since the spring is arranged at a position of the support sheet close to the heat-conducting film, when the cable is deformed due to external pressure, the spring provides extreme protection for the deformed support sheet, thereby preventing the support sheet from being excessively deformed and broken, and making the heat dissipation effect of the cable less easily affected.

[0020] By arranging the support sheet and the spring, the heat dissipation channel is divided into a number of independent channels by using the support sheet, and the spring is approximately horizontally placed near the heat-conducting film in the independent channel, thereby playing a role similar to a baffle, so that the cross-sectional area interval of the independent channel is reduced. Afterwards, when the cooling water flows through the independent channel, the water flow rate is intermittently accelerated, thereby improving the heat dissipation effect of the cable.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Example 1: Please refer to Figure 1-Figure 6 A heat dissipation wire and cable installed with an anti-breakage joint for an aluminum-clad steel core aluminum stranded wire, comprising a connecting end 1, two connecting ends 1, and electrode joints 2 are fixedly installed on the opposite sides of the two connecting ends 1. A conductor 3 (aluminum-clad steel core aluminum stranded wire) is arranged between the two connecting ends 1. The end of the conductor 3 facing the corresponding electrode joint 2 passes through the corresponding connecting end 1 and forms a fixed connection with the corresponding electrode joint 2. An electrode plate 4 is fixedly installed on the side of the electrode joint 2 facing away from the corresponding connecting end 1. An electrode connection hole 5 is opened inside the electrode plate 4 for connecting to power generation equipment or power-consuming equipment. A thermal conductive film 6 is sleeved between the two connecting ends 1 and located on the outer side of the conductor 3. The two ends of the thermal conductive film 6 are respectively fixedly sealed and connected to the connecting ends 1 in the corresponding directions. Between adjacent conductors 3 The space between the wire 3 and the heat-conducting film 6 is filled with heat-conducting carbon fiber bundles 7, the outer side of the heat-conducting film 6 is sleeved with a protective film 8, and the two sides of the protective film 8 are respectively fixedly and sealedly connected to the connecting ends 1 in the corresponding directions. The space between the protective film 8 and the heat-conducting film 6 is a heat dissipation channel, and the two connecting ends 1 are each provided with a water distribution cavity 9, and the two water distribution cavities 9 are connected through the heat dissipation channel. A water inlet hole 10 is provided inside one of the connecting ends 1, and the water inlet hole 10 connects the corresponding water distribution cavity 9 with the external environment, and a water outlet hole 11 is provided inside the other connecting end 1, and the water outlet hole 11 connects the corresponding water distribution cavity 9 with the external environment, the output end of the circulating water device is connected with the water inlet hole 10, and the input end of the circulating water device is connected with the water outlet hole 11 (the circulating water device is a prior art, such as a water pump, not shown in the figure).

[0032] When in use, since the heat dissipation channel composed of the thermally conductive film 6 and the protective film 8 surrounds the outside of the wire 3, and the excess space between the thermally conductive film 6 and the wire 3 is filled with the thermally conductive carbon fiber bundle 7, the heat generated by the wire 3 is not only directly transferred to the cooling water in the heat dissipation channel through contact with the thermally conductive film 6, but also indirectly transferred to the cooling water in the heat dissipation channel through the thermally conductive carbon fiber bundle 7 and the thermally conductive film 6. Through the above actions, the heat dissipation effect of the wire 3 is further improved.

[0033] See also Figure 1-Figure 6 Support sheets 12 are equidistantly arranged in the circumferential direction of the heat dissipation channel, and the support sheets 12 are made of elastic material.

[0034] The support sheet 12 is used to support the heat dissipation channel, so that an elastic buffer exists between the protective film 8 and the wire 3, so that when external pressure is applied to the cable, the elastic buffer offsets part of the pressure to a certain extent, thereby reducing the probability of cable damage.

[0035] Example 2: Please refer to Figure 1-Figure 6 This embodiment is a further improvement on the first embodiment, and the improvement lies in that: the support sheet 12 is an arc-shaped structure.

[0036] By setting the above structure, when the support sheet 12 is subjected to external pressure, it is easier to bend and deform, thereby further reducing the probability of the cable being damaged by pressure.

[0037] See also Figure 1-Figure 6 The support sheet 12 is made of elastic heat-conducting material, the outer side of the support sheet 12 is fixedly connected to the inner side of the protective film 8 , and the inner side of the support sheet 12 is fixedly connected to the outer side of the heat-conducting film 6 .

[0038] Since the support sheet 12 is fixedly connected to the heat-conducting film 6 and the support sheet 12 is made of elastic heat-conducting material, the contact area between the heat-conducting film 6 and the cooling water in the heat dissipation channel is indirectly increased, thereby improving the heat dissipation effect of the wire 3.

[0039] See also Figure 1-Figure 6 A spring 13 is sleeved on the outer side of the heat-conducting film 6 , a sliding hole 14 is opened inside the supporting sheet 12 , and the spring 13 passes through the sliding hole 14 , and the sliding hole 14 and the spring 13 form a sliding contact.

[0040] The support sheet 12 and the spring 13 have a certain limiting effect on the conductor 3. When a certain position of the cable tends to bend, the bending force will be blocked by the support sheet 12 and the spring 13 (due to the cable arrangement, when a certain section of the cable is bent, the corresponding support sheet 12 and the spring 13 are also bent and will not affect the cable arrangement), thereby reducing the probability of bending at a certain position of the cable and preventing the cable from being damaged.

[0041] Example 3: Please refer to Figure 1-Figure 6 This embodiment is a further improvement on the second embodiment, and the improvement lies in that: the distance between the spring 13 and the heat-conducting film 6 is smaller than the distance between the spring 13 and the protective film 8, the outer side of the support sheet 12 is fixedly sealed and connected to the inner side of the protective film 8, and the inner side of the support sheet 12 is fixedly sealed and connected to the outer side of the heat-conducting film 6.

[0042] Since the spring 13 is arranged at the position of the support sheet 12 close to the heat-conducting film 6, when the cable is subjected to external pressure and the protective film 8 drives the support sheet 12 to deform, the spring 13 plays an extreme protection role for the deformed support sheet 12, and prevents the support sheet 12 from excessive deformation and breakage (when the support sheet 12 is bent to a certain extent, it will be pressed on the outside of the spring 13. Since the cross-section of the spring 13 is approximately a circular ring, the deformed support sheet 12 is supported by the circular ring), so that the heat dissipation effect of the cable is not easily affected. At the same time, the support sheet 12 is used to separate the heat dissipation channel into several independent channels (the gap between the spring 13 and the sliding hole 14 is too small to easily affect drainage), and the spring 13 is approximately horizontally placed near the heat-conducting film 6 in the independent channel, thereby playing a role similar to a baffle, so that the cross-sectional area interval of the independent channel is reduced. Afterwards, in the process of cooling water flowing through the independent channel, the water flow rate is intermittently accelerated, thereby improving the heat dissipation effect of the cable.

[0043] Embodiment 4: Since the spring 13 is closer to the heat-conducting film 6 in the independent channel and the cross-section of the spring 13 is circular, when the water flows through the spring 13, a more complex flow pattern will be formed (the water flows upward or downward along the surface of the spring 13, thereby contacting and disturbing the water flowing nearby), thereby increasing the contact time between the water flow and the heat-conducting film 6, which is beneficial to the heat transfer.
