Description

Technical Field

[0001] The present invention relates to the technical field of cable heat dissipation, and in particular to an intelligent cable with liquid cooling and heat dissipation. Background Art

[0002] In today's power transmission field, cables play an extremely critical role. As power demand rises, cable current carrying capacity increases, and heat dissipation becomes a problem that needs to be solved urgently.

[0003] Existing cable cooling solutions primarily include natural air cooling, forced air cooling, and heat dissipation using thermally conductive materials. First, natural cooling relies on heat exchange between the cable and air, which is inefficient. In densely packed or enclosed environments, heat easily accumulates, causing rapid cable temperature rise, impacting current carrying capacity and lifespan, and even causing insulation breakdown. Second, while forced air cooling offers some improvement, it consumes significant energy. In harsh environments, such as dusty and humid areas, dust and moisture can affect heat dissipation, potentially causing safety incidents. Furthermore, its heat dissipation capacity is insufficient to meet the demands of high-load cables. Third, heat dissipation using thermally conductive materials is limited by the material's thermal conductivity and contact thermal resistance. Prolonged exposure to high temperatures can lead to changes in material properties and reduced heat dissipation efficiency.

[0004] In view of the defects of the above-mentioned non-liquid cooling solutions, there is an urgent need for a highly efficient liquid cooling method to overcome the insufficient heat dissipation of existing cables, provide a reliable solution for efficient heat dissipation and stable operation of cables, and meet the development requirements of modern power systems.

[0005] In the prior art, the disclosed invention patent, patent number: 202410618015.8, patent name "Liquid Cooling and Heat Dissipation Cable" invention patent, discloses a liquid cooling and heat dissipation technology, and its specific technology is: at least two liquid cooling and heat dissipation spiral metal transmission copper cable structures are provided in the cable, and the liquid cooling and heat dissipation spiral metal transmission copper cable structure includes a spiral metal tube, a copper cable layer and an insulation layer. During specific use, due to the close contact between the spiral metal tube and the copper cable layer, the heat generated by the copper cable layer is transferred to the liquid cooling oil by the spiral metal tube. Due to the rapid flow of the liquid cooling oil, the heat generated everywhere is quickly brought out of the cable, thereby achieving the purpose of cooling and heat dissipation.

[0006] However, the invention patent number: 202410618015.8, patent name "Liquid Cooling Heat Dissipation Cable" has the following shortcomings:

[0007] (1) Adding two spiral metal tubes to the cable will increase the material cost and transportation cost of the cable and sacrifice the flexibility of the cable;

[0008] (2) The heat generated by the copper cable layer can only be partially dissipated by conducting the closely contacted spiral metal tube to the liquid cooling oil inside the tube. Most of the heat does not contact the spiral metal tube and cannot be dissipated, resulting in low heat dissipation efficiency. Summary of the Invention

[0037] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] The present invention will be described in detail below with reference to the accompanying drawings:

[0040] A smart cable with liquid cooling, such as Figure 1 As shown, it includes a sealed cable segment 100 , an input cable segment 200 , an output cable segment 300 and a liquid cooling control device 400 .

[0041] The enclosed cable segment 100 is a completely sealed cable segment, and is mainly used for liquid cooling of the cable.

[0042] The input cable segment 200 is mainly used for transition connection between the power supply end and the enclosed cable segment 100 . The first end of the input cable segment 200 is connected to the power supply end, and the second end of the input cable segment 200 is connected to the first end of the enclosed cable segment 100 .

[0043] The output cable segment 300 is mainly used for transition connection between the enclosed cable segment 100 and the power end. The first end of the output cable segment 300 is connected to the power end, and the second end of the output cable segment 300 is connected to the second end of the enclosed cable segment 100.

[0044] The liquid cooling control device 400 is mainly used to promote heat dissipation in the enclosed cable segment 100 .

[0045] It should be noted that the enclosed cable segment 100 , the input cable segment 200 and the output cable segment 300 are an integrally formed cable structure.

[0046] It should be noted that the liquid cooling control device 400 is detachably installed at the junction of the enclosed cable segment 100 and the input cable segment 200 .

[0047] like Figure 3 As shown, a cross-sectional structural diagram of the enclosed cable segment 100, the input cable segment 200 and the output cable segment 300 is shown; the enclosed cable segment 100, the input cable segment 200 and the output cable segment 300 also include a cable outer shell 102, a cable inner shell 103, a live wire cable 104 and a neutral wire cable 105.

[0048] The live wire cable 104 and the neutral wire cable 105 are arranged inside the cable inner shell 103 .

[0049] The cable inner shell 103 is disposed inside the cable outer shell 102 .

[0050] In the input cable segment 200 and the output cable segment 300 , solid insulating material is filled between the cable inner shell 103 and the cable outer shell 102 .

[0051] In the input cable segment 200 and the output cable segment 300 , solid insulating material is filled between the live cable 104 and the neutral cable 105 and the cable jacket 102 .

[0052] As will be appreciated, the cable jacket 102 is preferably made of polyvinyl chloride (PVC). PVC's excellent mechanical properties provide adequate protection for the internal cable jacket 103 and various cable structures, protecting them from damage caused by external physical factors such as extrusion and collision. Furthermore, it exhibits strong chemical resistance, maintaining stable chemical properties in the face of harsh external chemical environments such as acid rain and industrial chemical pollutants, as well as long-term contact with internal insulating fluid and cooling oil. PVC is also relatively inexpensive, effectively controlling costs in large-scale production applications.

[0053] It is understood that cross-linked polyethylene (XLPE) can be used for the cable inner jacket 103. XLPE's excellent electrical insulation properties effectively insulate the internal live and neutral cables 104 and 105, preventing leakage. XLPE also exhibits excellent heat resistance, maintaining stable physical and electrical properties even when the insulating cooling oil absorbs significant heat, preventing softening and deformation due to temperature increases. XLPE also possesses high toughness, allowing it to withstand certain deformations during installation or use, such as bending and twisting, without breaking, thus safeguarding the integrity of the internal cable structure.

[0054] It is understood that the solid insulation material between the live and neutral cables 104, 105, and the cable jacket 102, and the solid insulation material between the cable jacket 102 and the inner cable jacket 103, are primarily made of materials with high dielectric strength, excellent heat resistance, and chemical stability, such as cross-linked polyethylene and rubber. These materials not only maintain stable insulation performance under normal conditions, but also reliably perform their insulation functions even when the cable generates heat during operation and is exposed to complex environmental factors, ensuring stable long-term cable operation.

[0055] It should be noted that if Figure 3As shown, in the enclosed cable segment 100 , the input cable segment 200 and the output cable segment 300 , the live cable 104 further includes a live conductor 1041 and a live protective shell 1042 ; the neutral cable 105 further includes a neutral conductor 1051 and a neutral protective shell 1052 .

[0056] It can be understood that the input cable segment 200 and the output cable segment 300 designed in this way not only ensure the stable transmission of power at the input and output ends of the cable, but also lay a solid foundation for the realization of the liquid cooling function of the closed cable segment 100 in the middle, so that the cable can effectively dissipate the heat generated when facing high-load power transmission, maintain a good working condition, significantly improve the service life and reliability of the cable, and meet the stringent requirements of modern complex power transmission scenarios.

[0057] like Figure 1 and Figure 3 As shown, the sealed cable segment 100 further includes a plurality of annular heat sinks 101 , an outer shell cavity 106 and an inner shell cavity 107 .

[0058] The plurality of annular heat sinks 101 are used for heat dissipation of the sealed cable segment 100 .

[0059] The outer shell cavity 106 is provided between the cable outer shell 102 and the cable inner shell 103 , and the outer shell cavity 106 is filled with insulating liquid cooling oil.

[0060] The inner shell cavity 107 is disposed in the cable inner shell 103 , and the inner shell cavity 107 is filled with insulating liquid cooling oil.

[0061] It should be noted that the dimensions of the plurality of annular heat sinks 101 are consistent with the cross-sectional dimensions of the cable housing 102 .

[0062] It should be noted that if Figure 1 As shown, the plurality of annular heat sinks 101 are evenly embedded in the cable housing 102 at a certain distance.

[0063] It is understandable that the annular heat sink 101 is preferably made of aluminum alloy, which has the advantages of being lightweight, having good thermal conductivity, and being highly corrosion-resistant. Its light weight does not add excessive additional weight to the cable as a whole, facilitating cable laying and installation; its excellent thermal conductivity can quickly diffuse the heat transferred from the insulating liquid cooling oil, improving heat dissipation efficiency; and its good corrosion resistance ensures that it can maintain a stable structure and heat dissipation performance in long-term and complex use environments, such as humid, acidic, and alkaline environments, thereby effectively ensuring the long-term and reliable operation of the heat dissipation system of the enclosed cable segment 100, extending the service life of the cable, reducing the risk of cable failure due to heat sink damage, and providing stable and safe protection for related power transmission or signal transmission.

[0064] As will be understood, the insulating liquid cooling oil is primarily composed of a mixture of high-purity mineral oil and special insulating additives. Mineral oil possesses excellent thermal conductivity and chemical stability, enabling it to quickly absorb and evenly distribute the heat generated by the sealed cable segment 100 during operation. The insulating additives further enhance the insulating properties of the liquid cooling oil, ensuring that it will not conduct electricity during prolonged contact with conductive components such as the live conductor 1041 and the neutral conductor 1051, thereby ensuring the electrical safety of the entire sealed cable segment 100.

[0065] It should be noted that if Figure 4 , which shows a cross-sectional structural diagram of an annular heat sink. Any of the plurality of annular heat sinks 101 is further provided with protrusions that are evenly and symmetrically arranged.

[0066] The protrusions are arranged on the inner ring of the annular heat sink 101 and / or the outer ring of the annular heat sink 101 .

[0067] It is understandable that if Figure 5The figure shows a cross-sectional view of a first sealed cable segment 100 with an annular heat sink 101. The raised points, evenly and symmetrically arranged on the inner and / or outer rings of the annular heat sink 101, increase the surface area of the annular heat sink 101, creating more contact surfaces with both the insulating cooling oil inside and the external air. When in contact with the insulating cooling oil, more contact points facilitate more efficient heat transfer from the cooling oil to the heat sink; when in contact with the external air, they also accelerate the rate of heat dissipation from the heat sink to the air. Furthermore, the even and symmetrical arrangement of the raised points helps maintain the structural stability of the heat sink and uniform heat conduction, preventing heat accumulation or poor conduction due to local structural variations. This further enhances the heat dissipation of the entire sealed cable segment 100, ensuring stable cable operation under various operating conditions, reducing potential risks associated with poor heat dissipation, extending the cable's service life, and improving its reliability. Furthermore, the even and symmetrical arrangement of the raised points on the outer ring of the annular heat sink 101 increases friction, making it easier for operators to grip the cable.

[0068] It should be noted that if Figure 2 As shown, the cable inner shell 103 further includes a single-circle complete through hole 1031 .

[0069] like Figure 6 , which shows a cross-sectional view of a second sealed cable segment 100 having an annular heat sink 101 , wherein the single circle of completely through holes 1031 are evenly arranged on the cable inner shell 103 .

[0070] The single-circle complete through hole 1031 is used to penetrate the outer shell cavity 106 and the inner shell cavity 107 to achieve flow exchange of the insulating liquid cooling oil in the outer shell cavity 106 and the insulating liquid cooling oil in the inner shell cavity 107 .

[0071] It should be noted that the single circle of complete through holes 1031 is composed of 6 complete through holes 1031 .

[0072] It is understood that the single-circle, fully through-hole arrangement 1031 uniformly arranged throughout the cable inner shell 103 plays a crucial role in the heat dissipation system of the entire enclosed cable segment 100. By connecting the outer shell cavity 106 and the inner shell cavity 107, the insulating liquid cooling oil in each cavity can flow interchangeably. This flow interchange mechanism helps maintain the temperature uniformity of the insulating liquid cooling oil throughout the cable structure. For example, when the insulating liquid cooling oil in the inner shell cavity 107 heats up due to heat absorption, the interconnection provided by the fully through-hole arrangement 1031 allows the high-temperature insulating liquid cooling oil to flow with the relatively low-temperature liquid cooling oil in the other cavity, thereby promoting a more even distribution of heat throughout the liquid cooling oil system within the cable. Furthermore, the high-temperature insulating liquid cooling oil flowing into the outer shell cavity 106 can simultaneously dissipate heat externally through the several annular heat sinks 101, rapidly reducing the cable temperature. This not only improves the heat dissipation efficiency of the insulating liquid cooling oil, but also effectively avoids the occurrence of local overheating, thereby ensuring that the internal components of the cable operate stably in a suitable temperature environment, and reducing a series of problems such as insulation performance degradation and accelerated cable aging that may be caused by excessive temperature differences.

[0073] It should be noted that if Figure 2 As shown, the cable inner shell 103 further includes a single-circle one-way through hole 1032 .

[0074] like Figure 7 , which shows a cross-sectional view of a third type of sealed cable segment 100 having an annular heat sink 101 , wherein the single-circle one-way through holes 1032 are evenly arranged on the inner ring of the cable inner shell 103 .

[0075] The single-circle one-way through hole 1032 is used for one-way communication between the outer shell cavity 106 and the inner shell cavity 107 , so as to enable the insulating liquid cooling oil in the outer shell cavity 106 to flow into the inner shell cavity 107 .

[0076] It should be noted that the single-circle one-way through hole 1032 is composed of 6 one-way through holes 1032.

[0077] It is understood that the single-circle one-way through holes 1032 are evenly distributed on the cable inner shell 103. Its unique one-way penetration function enables the insulating liquid cooling oil in the outer shell cavity 106 to flow into the inner shell cavity 107. It can control the flow direction of the liquid cooling oil in a targeted manner according to specific needs. For example, when the live cable 1041 is energized, heat is generated. When a large amount of heat is generated in the inner shell cavity 107 and absorbed by the liquid cooling oil in the inner shell cavity 107, insulating liquid cooling oil with a higher temperature is formed. The insulating liquid cooling oil with a higher temperature expands and flows into the outer shell cavity 106 through the full through hole 1031, forcing the insulating liquid cooling oil with a lower temperature in the outer shell cavity 106 to flow into the inner shell cavity 107 in an orderly manner through the one-way through hole 1032. On the one hand, heat neutralization between the outer shell cavity 106 and the inner shell cavity 107 is achieved. On the other hand, the heat can be further diffused in the area involved in the outer shell cavity 106, and absorbed and dissipated outwards through the annular heat sink 101, so that the heat can be conducted and dissipated more deeply inside the entire cable, thereby optimizing the entire heat dissipation process, improving the heat dissipation effect, ensuring that the cable can maintain a good temperature state under different working conditions, and ensuring the normal operation and service life of the cable.

[0078] It should be noted that if Figure 2 As shown, the single-turn full through hole 1031 is provided on the first end side of the cable inner shell 103 .

[0079] The first end side of the cable inner shell 103 is an end close to the input cable segment 200 .

[0080] It should be noted that if Figure 2 As shown, the single-circle one-way through hole 1032 is provided on the second end side of the cable inner shell 103 .

[0081] The second end side of the cable inner casing 103 is an end close to the output cable segment 300 .

[0082] It is understandable that a single-circle complete through hole 1031 is provided on one side of the sealed cable segment 100, and a single-circle one-way through hole 1032 is provided on the other side of the sealed cable segment 100. This spacing arrangement constructs a more sophisticated and efficient liquid cooling oil flow network. Figure 9As shown, when high-temperature insulating liquid cooling oil flows out of full-through hole 1031, it squeezes and forces the low-temperature insulating liquid cooling oil in one-way hole 1032 to flow into inner shell cavity 107. This allows the insulating liquid cooling oil to flow between outer shell cavity 106 and inner shell cavity 107 with both bidirectional flexibility and unidirectional control. For example, when live cable 1041 is energized and generates heat, a large amount of heat is generated in inner shell cavity 107. This heat is absorbed by the liquid cooling oil in inner shell cavity 107, forming higher-temperature insulating liquid cooling oil. This higher-temperature insulating liquid cooling oil expands and flows through full-through hole 1031 into outer shell cavity 106. However, one-way hole 1032 ensures that the lower-temperature liquid cooling oil in outer shell cavity 106 can flow to the higher-temperature inner shell cavity 107, thus fulfilling its unidirectional flow guidance function. This coordinated layout can more accurately control the flow path and speed of the insulating liquid cooling oil, flexibly adjust the heat dissipation strategy according to the actual heat distribution of the cable during operation, maximize the heat dissipation efficiency of the entire enclosed cable segment 100, and ensure that the cable always maintains good performance and stable working condition under complex and changing working conditions.

[0083] like Figure 8 As shown, the liquid cooling control device 400 further includes a main control unit 401 , an AC / DC unit 402 , a switch MOS tube 403 , an electric pump 404 and a temperature sensor 405 .

[0084] An input end of the AC / DC unit 402 is connected to the live conductor 1041 in the input cable segment 200 .

[0085] The first output terminal of the AC / DC unit 402 is connected to the first input terminal of the main control unit 401 .

[0086] The second output terminal of the AC / DC unit 402 is connected to the input terminal of the switch MOS transistor 403 .

[0087] The second input terminal of the main control unit 401 is connected to the temperature sensor 405 .

[0088] The output end of the main control unit 401 is connected to the control end of the switch MOS tube 403 .

[0089] The output end of the switch MOS tube 403 is connected to the electric pump 404 .

[0090] The temperature sensor 405 is disposed in the inner shell cavity 107 through the single-circle complete through hole 1031 .

[0091] It is understandable that the liquid cooling control device 400 forms an intelligent liquid cooling control system through such a connection method. Figure 10As shown, the AC / DC unit 402 can convert the AC power transmitted from the input cable segment 200 into DC power, providing appropriate power to the main control unit 401 and the electric pump 404. The temperature sensor 405 monitors the temperature of the live cable 104 in the closed cable segment 100 in real time and transmits the data to the main control unit 401. The main control unit 401 analyzes and determines the received temperature information. When the temperature exceeds the set threshold, the main control unit 401 sends a control signal to the switch MOS tube 403 to turn on the switch MOS tube 40, thereby starting the electric pump 404. Figure 9 As shown, when the electric pump 404 is in operation, it can promote the circulation of insulating liquid cooling oil between the outer shell cavity 106 and the inner shell cavity 107 according to a predetermined flow path, thereby accelerating the transfer and dissipation of heat, ensuring that the temperature of the enclosed cable segment 100 is always within a reasonable range, ensuring the stable operation and safety performance of the cable, and effectively extending the service life of the cable to adapt to various complex power transmission environments and changes in working conditions.

[0092] It can be understood that the setting of the liquid cooling control device 400, without the need for additional power supply, uses the live wire and neutral wire of the cable itself to enable the electric pump to promote the accelerated circulation of the insulating liquid cooling oil between the outer shell cavity 106 and the inner shell cavity 107 along a predetermined flow path.
