Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cables for new energy vehicles, and particularly relates to a novel heat dissipation cable. BACKGROUND

[0002] New energy vehicles generally use ternary lithium and lithium iron phosphate batteries as power sources, and are driven by electric energy to achieve efficient operation, and have the advantages of high environmental protection energy efficiency, low use cost, high operation efficiency, etc. In the production and manufacturing process of new energy vehicles, cables are needed to realize the electrical connection of the electric drive system. In the operation process of new energy vehicles, the cables will inevitably heat up, especially in summer when the ambient temperature is high, so there are special requirements for the cables used to have good heat dissipation performance. However, some heat dissipation cables in the prior art are not directly used in the production and manufacturing of new energy vehicles, such as the invention disclosed in the application publication CN 118366719 A, which provides a liquid-cooled heat dissipation cable including an insulating outer cover, a plurality of signal transmission lines, a plurality of power lines, a PE cable, an oil supply pipe, and at least two liquid-cooled heat dissipation spiral metal transmission copper cable structures. The plurality of signal transmission lines, the plurality of power lines, the PE cable, the oil supply pipe, and the at least two liquid-cooled heat dissipation spiral metal transmission copper cable structures are all arranged in the insulating outer cover. The at least two liquid-cooled heat dissipation spiral metal transmission copper cable structures are arranged in the insulating outer cover and are used for signal transmission and heat dissipation. The oil supply pipe is used to supply liquid cooling oil to the liquid-cooled heat dissipation spiral metal transmission copper cable structure. The invention has the advantages of good heat dissipation effect, reduced heat generation, longer overall service life, higher safety, etc. If it is directly used in new energy vehicles, an oil supply structure needs to be added, which requires the structure of the new energy vehicle to be optimized and designed again, and also increases the use and maintenance costs. SUMMARY

[0003] In view of the deficiencies in the prior art, the present application provides a novel heat dissipation cable, which solves the problem that the heat dissipation cable in the prior art cannot be used in new energy vehicles.

[0004] According to an embodiment of the present invention, a novel heat dissipation cable includes a sheathing layer comprising a solid half-sleeve and a hollow half-sleeve forming a tube with the solid half-sleeve. The hollow half-sleeve is located above the solid half-sleeve and has a hollow cavity inside. It also includes multiple cable cores, with the sheathing layer covering all the cable cores. Furthermore, it includes an inner core shaft, with all the cable cores arranged around it. The inner core shaft is also fixedly connected to a first radial shaft extending into the hollow half-sleeve. The first radial shaft extends into the hollow cavity and is fixedly connected to a first support plate abutting against the inner wall of the hollow cavity opposite to the inner core shaft. The sheathing layer also has several pairs of inlets and outlets communicating with the hollow cavity and located on both sides of the first radial shaft. The inner core shaft and the first radial shaft allow heat generated by the cable cores to be conducted outwards to the hollow cavity, and then dissipated outwards through the inlets and outlets. Ultimately, the novel heat dissipation cable provides excellent heat dissipation, has minimal impact on the structure of new energy vehicles, does not require additional maintenance, and has low usage and maintenance costs. This solves the problem that existing heat dissipation cables cannot be used in new energy vehicles.

[0005] Furthermore, the cross-section of the hollow cavity is arc-shaped, with both ends of the arc extending downwards and each end connected to the outside through multiple channels, and several pairs of inlets and outlets located above the channels.

[0006] Furthermore, multiple partitions are fixedly installed inside the hollow cavity, with the partitions fixed to the middle sections of the upper and lower walls of the hollow cavity.

[0007] Furthermore, one end of the first tray is embedded in one side of the partition, and the other end is fixed to the first radial axis.

[0008] Furthermore, an inner lining half-set is also fixedly installed inside the solid half-set.

[0009] Furthermore, the inner core shaft is also fixedly connected to a pair of second radial shafts symmetrically arranged on both sides of the first radial shaft, and the ends of the two second radial shafts facing away from the inner core shaft are also fixedly connected to a second support plate that abuts against the inner lining half-sleeve.

[0010] Furthermore, the inner lining half is also fixedly connected with limiting plates located in the two channels respectively.

[0011] Furthermore, multiple connecting segments are fixedly connected to both ends of the inner lining half-sleeve, and each connecting segment is fixedly extended into the adjacent channel and fixedly connected to a limiting piece.

[0012] Furthermore, the channel is an arc-shaped structure extending downwards, with the lower end facing away from the inner core.

[0013] Furthermore, a first radiating axis and two second radiating axes are equidistantly arranged around the inner core shaft and form a group, while multiple groups of first and second radiating axes are equidistantly arranged along the length direction of the inner core shaft.

[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] The hollow cavity provided in the upper part of the novel heat dissipation cable can be communicated with the outside through the inlet and outlet on both sides, the heat generated by the cable core wrapped in the wrapping layer can be guided to the hollow cavity through the first radiation shaft, and then dissipated to the outside, thereby achieving good heat dissipation effect. The application of the novel heat dissipation cable to new energy automobile production and manufacturing does not require additional matching structure, thus having little influence on the structure of the new energy automobile itself, and does not additionally increase a large amount of maintenance work, and the use and maintenance costs are both low, thereby solving the problem that the heat dissipation cable in the prior art cannot be used on the new energy automobile.

[0024] In an exemplary embodiment, as Figure 1 , 2As shown, the embodiment provides a new heat dissipation cable, which comprises a plurality of cable core wires 1, and a wrapping layer 2, the wrapping layer 2 comprises a solid half sleeve 3 and a hollow half sleeve 4 which is enclosed with the solid half sleeve 3 into a tubular shape, the hollow half sleeve 4 is located above the solid half sleeve 3 and a hollow cavity 5 is arranged in the hollow half sleeve 4; the wrapping layer 2 is sleeved outside all the cable core wires 1; the new heat dissipation cable further comprises an inner core shaft 6, all the cable core wires 1 are arranged around the outer side of the inner core shaft 6, and the inner core shaft 6 is further fixedly connected with a first radiation shaft 7 extending to the hollow half sleeve 4, the first radiation shaft 7 extends into the hollow cavity 5 and is further fixedly connected with a first supporting plate 8 abutting against the inner wall of the hollow cavity 5 away from the inner core shaft 6; a plurality of pairs of inlets and outlets 9 are further arranged on the wrapping layer 2 and communicate with the hollow cavity 5 and are located on both sides of the first radiation shaft 7, the arranged inlets and outlets 9 play a role in communicating the inside and outside of the hollow cavity 5, the heat generated by the cable core wires 1 wrapped in the wrapping layer 2 can be conducted to the hollow cavity 5 through the first radiation shaft 7, and then dissipated to the outside, thereby achieving good heat dissipation effect, at the same time, the new heat dissipation cable provided by the scheme is used on a new energy vehicle without the need for additional adjustment and optimization of the structure of the new energy vehicle, and does not additionally increase a large amount of maintenance work, and the use and maintenance costs are relatively low, solving the problem that the heat dissipation cable in the prior art cannot be used on the new energy vehicle; more specifically, the upper half of the new heat dissipation cable is provided with the hollow cavity 5, the first supporting plate 8 is arranged inside to provide support, so that the hollow cavity 5 is not prone to collapse during installation of the new heat dissipation cable and after installation, the first supporting plate 8 is connected with the inner core shaft 6 through the first radiation shaft 7, so that the inner core shaft 6 indirectly provides support for the first supporting plate 8, so that the first supporting plate 8 can provide more stable support; further, the inner lining half sleeve 10 is further fixedly arranged in the solid half sleeve 3 arranged in the lower half, the inner lining half sleeve 10 is used to improve the strength of the solid half sleeve 3, so that the overall wrapping layer 2 has better stability, more specifically, the inner core shaft 6 is further fixedly connected with a pair of second radiation shafts 11 symmetrically arranged on both sides of the first radiation shaft 7, and the end portions of the two second radiation shafts 11 away from the inner core shaft 6 are further fixedly connected with a second supporting plate 12 abutting against the inner lining half sleeve 10, the second supporting plate 12 is similar to the first supporting plate 8, so that the inner lining half sleeve 10 can be more stably supported, and the overall new heat dissipation cable has better mechanical stability; the first radiation shaft 7 and the second radiation shaft 11 can be equidistantly arranged around, so that the first supporting plate 8 and the second supporting plate 12 are uniformly arranged around the outer side of the inner core shaft 6, and can provide more balanced support during installation of the new heat dissipation cable.

[0025] As Figures 1-3As shown, the cross section of the hollow cavity 5 is arc-shaped, and the first supporting plate 8 is also arc-shaped, which better supports the hollow cavity 5. The two ends of the arc-shaped hollow cavity 5 extend downward, that is, the two sides of the hollow cavity 5 extend downward, respectively, and embrace the cable core wire 1, which can cover a larger range of the cable core wire 1. More specifically, the hollow half sleeve 4 near the cable core wire 1 is thin, and the heat generated by the cable core wire 1 can also be transferred to the hollow cavity 5 through the thin part, thereby achieving a better heat dissipation effect. The two ends of the arc-shaped hollow cavity 5 are also respectively communicated with the outside through a plurality of channels 13, and a plurality of pairs of inlets and outlets 9 are located above the channels 13. The inlets and outlets 9 are high, and the channels 13 are low. The channels 13 also make the hollow cavity 5 more smoothly communicate with the outside, thereby achieving a better heat dissipation effect. At the same time, the channels 13 are arc-shaped structures extending downward, and the lower end is away from the inner core shaft 6. In this way, the heat in the hollow cavity 5 can flow more smoothly downward, thereby being more efficiently conducted to the outside. When the new heat dissipation cable is installed under the chassis of the new energy vehicle, the new heat dissipation cable will have a high-speed air flow below it as the new energy vehicle travels. The air pressure below the channel 13 is low, thereby being able to more quickly conduct the air in the hollow cavity 5 to the outside. At the same time, the inlets and outlets 9 above can supply air to enter the hollow cavity 5, thereby quickly updating the air in the hollow cavity 5, and thereby achieving a better heat dissipation effect.

[0026] As shown in the drawings, Figures 1-4 In a further aspect, a plurality of partitions 14 are fixedly arranged in the hollow cavity 5. The partitions 14 are fixed to the middle sections of the upper and lower walls of the hollow cavity 5. The partitions 14 are arranged in the hollow cavity 5, specifically at the highest middle section. The partitions 14 are also arc-shaped and extend downward at the two ends. However, the partitions 14 do not completely separate the hollow cavity 5, and the hollow cavity 5 is continuous on both sides of the partitions 14. The partitions 14 also support the hollow cavity 5. At the same time, one end of the first supporting plate 8 is embedded in one side of the partition 14, and the other end is fixed to the first radiation shaft 7. In this way, the partition 14 and the first radiation shaft 7 jointly support the first supporting plate 8, so that the first supporting plate 8 can be arranged to be longer and better support the hollow cavity 5. In further detail, the first radiation shaft 7 and the second radiation shaft 11 are equidistantly arranged around the inner core shaft 6 and form a group. A plurality of groups of the first radiation shaft 7 and the second radiation shaft 11 are equidistantly arranged along the length of the inner core shaft 6. The groups are equidistantly arranged. In this way, the entire new heat dissipation cable can be supported. At the same time, the inlets and outlets 9, the channels 13, and the partitions 14 are also arranged in multiple groups, thereby achieving a heat dissipation effect on the entire new heat dissipation cable and having better stability.

[0027] As shown in the drawings, Figures 1-4As shown, in a more detailed scheme, the second radiation shaft 11 arranged can also conduct heat to the inner lining half cover 10, and the inner lining half cover 10 arranged is also arc-shaped like the solid half cover 3, which can disperse heat on a wider arc surface, and then disperse outward through the outer wall of the solid half cover 3, and further, the second supporting plate 12 is also arc-shaped, which can more efficiently support the inner lining half cover 10 and better conduct heat to the inner lining half cover 10; in a more detailed scheme, some outwardly protruding protruding columns 15 outside the solid half cover 3 can be fixed on the outer wall of the inner lining half cover 10, and the end of the protruding column 15 away from the inner lining half cover 10 is connected with the outside, so that the heat on the inner lining half cover 10 can be more efficiently conducted outward, achieving a better heat dissipation effect; further, the inner lining half cover 10 arranged extends upward on both sides in an arc shape and extends into two channels 13 respectively, so that the heat on the inner lining half cover 10 can also be conducted to the channels 13, and then conducted outward; further, the inner lining half cover 10 is also fixedly connected with limiting pieces 16 located in the two channels 13 respectively, the limiting piece 16 is tightly attached to the inner wall of the channel 13 below, and the limiting piece 16 and the channel 13 are also arc-shaped, the limiting piece 16 makes the both side ends of the inner lining half cover 10 more stable, and the limiting piece 16 can also guide the airflow in the channel 13, and the heat of the inner lining half cover 10 can also be indirectly and more efficiently dissipated in the channel 13 through the limiting piece 16, and then more efficiently dissipated to the outside through the channel; further, the inner core shaft 6, the first radiation shaft 7, the inner lining half cover 10, the second radiation shaft 11, the protruding column 16 and other support structures in the scheme can be made of metal with good thermal conductivity, such as copper, and the cable core 1 is a conductive cable wrapped with insulating rubber or an optical fiber cable, and a plurality of cable cores 1 are equally arranged between adjacent second radiation shafts 11.
