Description

Technical Field

[0001] The invention relates to liquid cooling cable technical equipment in cable technology, in particular to a series-flow liquid cooling cable. Background Art

[0002] In the prior art, the technical means of liquid cooling cables are mostly to set inner tubes of various shapes inside the cable, and then fill the tube with coolant. The coolant absorbs the heat generated by the cable when it is working, thereby effectively reducing the internal temperature of the cable. The specific structural design is as follows.

[0003] For example: the "liquid-cooled cable" disclosed in the publication (announcement) number: CN114267486A, the technical solution includes a liquid cooling channel and at least one group of wire cores with a fan-shaped cross section, the liquid cooling channel includes an inner liquid cooling channel and an outer liquid cooling channel, and at least one group of connecting channels, the outer liquid cooling channel is connected to the inner liquid cooling channel through the connecting channel, and the cooling medium flows inside the liquid cooling channel; the wire core is arranged on the outer periphery of the inner liquid cooling channel and the inner periphery of the outer liquid cooling channel, and the connecting channel is arranged in the radial direction of the liquid-cooled cable and separates each of the wire cores. The present invention adds liquid cooling channels inside and outside the wire core to ensure the cooling effect of the cable to the greatest extent, thereby improving the current carrying capacity and service life of the cable.

[0004] For example: the "liquid-cooled cable" disclosed in the publication (announcement) number: CN218568500U, the technical solution includes a sheath, a liquid cooling tube, a positive cable group, a negative cable group and a cable filler, the sheath has a cavity, the liquid cooling tube is arranged in the cavity, the liquid cooling tube is used to flow the cooling liquid, the positive cable group includes a plurality of positive cables arranged in the cavity, at least one positive cable is arranged closely to the liquid cooling tube, a first gap is formed between the positive cable and another positive cable and / or the liquid cooling tube and / or the inner wall of the sheath, the negative cable group includes a plurality of negative cables arranged in the cavity, at least one negative cable is arranged closely to the liquid cooling tube, a second gap is formed between the negative cable and another negative cable and / or the liquid cooling tube and / or the inner wall of the sheath, and the cable filler fills the first gap and / or the second gap. The technical solution of this utility model is to optimize the internal structure of the liquid cooling cable, reduce the diameter of the liquid cooling cable and improve its heat dissipation efficiency.

[0005] In the above-mentioned technical solutions, a structure for containing coolant is arranged inside the cable, such as the fan-shaped liquid cooling channel in the above-mentioned technical solution, and the liquid cooling tube and other structures arranged inside, in which the coolant can be placed, so as to better absorb heat; however, in the above-mentioned technical solution, when it is used specifically, the liquid cooling tubes are not connected to each other, which results in that if the cable is placed on the ground or other positions, the heat in the part in contact with the ground is not easy to dissipate, and the heat in this part cannot enter other liquid cooling tubes, which will cause heat accumulation; and most of the prior arts directly arrange the liquid cooling tube at the innermost position. The advantage of such a design is that it is easy to install, but although the heat accumulated in the internal position can absorb part of the heat, it still cannot achieve heat dissipation on the innermost side, and the structural setting is not reasonable enough.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a serial liquid cooling cable with a reasonable structure and improved heat dissipation efficiency. Summary of the invention

[0007] The purpose of the present invention is to provide a series flow liquid cooling cable to address the deficiencies of the prior art; the technical solution is as follows:

[0008] A stream-type liquid-cooled cable, comprising a cable core and a liquid-cooled frame for use therewith; the liquid-cooled frame comprises an inner ring frame and an outer ring frame, the inner ring frame and the outer ring frame are arranged concentrically, and a partitioning partition is arranged between the inner ring frame and the outer ring frame, the area between the inner ring frame and the outer ring frame is divided into a plurality of placement areas by the partitioning partition, and the cable core is correspondingly arranged in the placement area, and the area in the inner ring frame is arranged as a liquid-cooled area, and a coolant is correspondingly arranged in the liquid-cooled area;

[0009] A wrapping layer is further arranged outside the outer ring skeleton, an outer shielding layer is further arranged outside the wrapping layer, and an outer sheath is further arranged outside the outer shielding layer.

[0010] Furthermore, the inner ring skeleton and the partition partition are also provided with series flow holes, through which the liquid cooling area in the inner ring skeleton is connected to the placement area in the outer ring skeleton, so that the coolant in the liquid cooling area flows into the placement area through the series flow holes.

[0011] Furthermore, the partitioning partition is also provided with series flow holes, through which adjacent placement areas are connected correspondingly, and the coolant in the adjacent placement areas and the coolant in the liquid cooling area can flow in series accordingly.

[0012] Furthermore, the bottom of the cable core is tightly attached to the inner ring frame in the placement area, and the two sides are tightly attached to the partition partitions; and the flow holes on the inner ring frame corresponding to each placement area are arranged at the gap positions on both sides, so that the coolant can smoothly enter the placement area; the flow holes on the partition partitions are arranged on the upper and lower sides, so that the coolant in adjacent placement areas can flow smoothly with each other.

[0013] Furthermore, the inner ring skeleton and the outer ring skeleton are both configured as copper tube structures, the partition partition is configured as a plate structure of copper material, and the series flow holes are evenly distributed.

[0014] Furthermore, there are six partitioning partitions in total, six corresponding placement areas in total, and six cable cores in total, with one cable core being placed in each placement area.

[0015] Furthermore, the cable core includes an innermost conductor, an insulating layer outside the conductor, an inner shielding layer outside the insulating layer, a waterproof layer outside the inner shielding layer, and an inner sheath arranged outside the waterproof layer.

[0016] Beneficial effects: The present invention has the following beneficial effects:

The outer frame constitutes the installation area of ​​the cable inner core, while the inner frame constitutes the cooling area of ​​the coolant. The coolant is placed in the inner frame. When the cable inner core is working, the heat generated inside is directly absorbed by the coolant, which can effectively reduce the cable temperature. The structure is reasonable;

[0018] 2) In this device, a series of flow holes are provided on the inner frame, so that the coolant in the cooling area of ​​the inner frame can enter the placement area of ​​the outer frame. With this design, on the one hand, the coolant directly enters the placement area to surround the inner core of the cable, which can efficiently absorb the heat of the inner core of the cable. On the other hand, after the coolant absorbs the heat in the placement area, the heat can be more easily dissipated through the outer wrapping layer and the outer sheath. The structure is very reasonable.

[0019] 3) In this device, flow holes are also set on the partition plate, so that the coolant in the adjacent placement areas can flow to each other. The heat absorbed by the coolant is averaged in each placement area under the effect of flow. After the heat is averaged, the heat of the entire cable is effectively reduced, and it is also easier to dissipate heat;

[0020] 4) The specific location of the string flow holes is also designed in this device.

DETAILED DESCRIPTION

[0026] 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.

[0027] like Figure 1 As shown, a stream-type liquid-cooled cable comprises a cable core 1 and a liquid-cooled skeleton for use therewith; the liquid-cooled skeleton comprises an inner ring skeleton 2 and an outer ring skeleton 3, the inner ring skeleton 2 and the outer ring skeleton 3 are arranged concentrically, and a partitioning partition 4 is arranged between the inner ring skeleton 2 and the outer ring skeleton 3, the area between the inner ring skeleton 2 and the outer ring skeleton 3 is divided into a plurality of placement areas 5 by the partitioning partition 4, and the cable core 1 is correspondingly arranged in the placement area 5, and the area in the inner ring skeleton 2 is arranged as a liquid-cooled area 6, and a coolant is correspondingly arranged in the liquid-cooled area 6;

[0028] A wrapping layer 7 is further disposed outside the outer ring skeleton 3 , an outer shielding layer 8 is further disposed outside the wrapping layer 7 , and an outer sheath 9 is further disposed outside the outer shielding layer 8 .

[0029] Flow holes 10 are also provided on the inner ring skeleton 2 and the partition partition 4. Through the provided flow holes 10, the liquid cooling area 6 in the inner ring skeleton 2 is connected to the placement area 5 in the outer ring skeleton 3, so that the coolant in the liquid cooling area 6 flows into the placement area 5 through the flow holes 10.

[0030] The partitioning partition 4 is also provided with a series flow hole 10, through which the adjacent placement areas 5 are connected correspondingly, and the coolant in the adjacent placement areas 5 and the coolant in the liquid cooling area 6 can flow in series accordingly.

[0031] The bottom of the cable core 1 is tightly attached to the inner ring frame 2 in the placement area 5, and the two sides are tightly attached to the partition baffles 4; the flow holes 10 on the inner ring frame 2 corresponding to each placement area 5 are arranged at the gap positions on both sides, so that the coolant can smoothly enter the placement area 5; the flow holes 10 on the partition baffles 4 are arranged on the upper and lower sides, so that the coolants in adjacent placement areas 5 can flow smoothly with each other.

[0032] The inner ring frame 2 and the outer ring frame 3 are both configured as copper tube structures, the partition plate 4 is configured as a plate structure of copper material, and the flow holes 10 are evenly distributed.

[0033] There are six partition plates 4 in total, six corresponding placement areas 5 in total, and six cable cores 1 in total. One cable core 1 is placed in each placement area 5 .

[0034] The cable core 1 includes an innermost conductor 101 , an insulating layer 102 outside the conductor 101 , an inner shielding layer 103 outside the insulating layer 102 , a waterproof layer 104 outside the inner shielding layer 103 , and an inner sheath 105 arranged outside the waterproof layer 104 .

[0035] In the technical solution of the present device, firstly, an inner frame and an outer frame are provided. The outer frame constitutes the installation area of ​​the cable inner core, and the inner frame constitutes the cooling area of ​​the coolant. The coolant is placed in the inner frame. When the cable inner core is working, the heat generated inside is directly absorbed by the coolant, which can effectively reduce the cable temperature and has a reasonable structure.

[0036] However, in the above technical solution, the coolant only exists in the cooling area of ​​the inner skeleton and is located at the innermost position. Although the heat is absorbed, it is not easy to dissipate. The present device correspondingly sets series flow holes on the inner skeleton so that the coolant in the cooling area of ​​the inner skeleton can enter the placement area of ​​the outer skeleton. With this design, on the one hand, the coolant directly enters the placement area to surround the inner core of the cable, and can efficiently absorb the heat of the inner core of the cable. On the other hand, after the coolant absorbs the heat in the placement area, the heat can be more easily dissipated through the outer winding layer and the outer sheath. The structure is very reasonable.

[0037] In addition, in this device, series flow holes are arranged on the partition partitions, so that the coolants in adjacent placement areas can flow to each other. The heat absorbed by the coolant is averaged in each placement area under the effect of series flow. After the heat is averaged, the heat of the entire cable is effectively reduced, and it is also easier to dissipate heat.

[0038] like Figure 3 As shown, the specific setting position of the string flow holes is also designed in the present device. The string flow holes on the inner skeleton are arranged on both sides of the cable core, which can smoothly enter the placement area; the string flow holes on the partition partition are arranged on the upper and lower sides, which can also realize the smooth entry and exit of the coolant, and the structural design is very reasonable; in addition, a waterproof layer is also arranged in the cable core of the present device to prevent the coolant from damaging the cable core, and the structural design is reasonable.

[0039] 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.
