Description

Technical Field

[0001] The present invention relates to the technical field of cable heat dissipation, and in particular to a cable with an air-cooled heat-conducting and heat-dissipating structure. Background Art

[0002] In modern power transmission systems, cable heat dissipation has become a key bottleneck restricting the improvement of current-carrying capacity. Especially with the integration of new energy power generation and the popularization of electric vehicles, the operating temperature of high-current cables continues to rise, leading to accelerated insulation degradation, reduced current carrying capacity, and frequent safety hazards. Current mainstream air-cooling solutions face three limitations: 1) Passive air cooling has low efficiency Natural convection heat dissipation relies on ambient air flow. When cables are densely laid or in closed spaces, the heat dissipation efficiency drops sharply and cannot meet the continuous heat dissipation requirements of high-current cables.

[0003] 2) Active air cooling system is bulky Traditional forced air cooling requires an external fan and independent power supply interface, which not only increases energy consumption and maintenance costs, but also faces reliability risks such as air supply interruption and channel blockage when moving on a vehicle or in dusty environments.

[0004] 3) Hybrid structure heat dissipation is hindered When attempting to enhance airflow heat exchange by integrating heat dissipation elements (such as metal spring channels) inside the cable, the heat from the cable core cannot be efficiently transferred to the heat dissipation interface because the insulation material layer blocks the heat conduction path.

[0005] In the prior art, the disclosed invention patent, patent number: 202310707618.0, patent name "A heat-dissipating cable for new energy vehicles and its heat-dissipating structure forming device", discloses a heat-dissipating cable for new energy vehicles and its heat-dissipating structure forming device, wherein the cable includes a cable core and an insulation layer, a shielding layer and an outer sheath wrapped around the outside of the cable core in sequence, a heat-dissipating structure is arranged between the shielding layer and the outer sheath, and the heat-dissipating structure includes a heat-dissipating spring, a limit block and a cavity. The heat-dissipating spring and the cavity are arranged between the limit blocks at intervals along the cable axis. The heat-dissipating spring includes a spiral body sleeved on the outside of the shielding layer and an extension piece extending to the inside of the outer sheath. The heat-dissipating cable for new energy vehicles in the present invention is provided with a heat-dissipating structure inside the cable. The heat-dissipating spring not only has heat dissipation capability itself, but also can form a heat-dissipating channel with the cavity to achieve an air-cooling effect of the cable. The heat-dissipating structure forming device is used to attach the heat-dissipating structure to the outside of the braided layer of the cable, and automatically complete the formation of the limit block, the installation of the heat-dissipating spring, and the molding of the cavity and the outer sheath.

[0006] However, the invention patent number: Patent No.: 202310707618.0, patent name "A heat dissipation cable for new energy vehicles and its heat dissipation structure forming device" has the following shortcomings: (1) Forced air cooling relies on continuous air supply from an external fan (an independent power supply interface is required); (2) The heat generated by the copper cable will be absorbed by the insulation material in the cable, resulting in low heat dissipation efficiency. Summary of the Invention

[0007] In response to the above technical problems, the present invention proposes a cable with an air-cooled heat-conducting and heat-dissipating structure, which can improve air-cooled heat dissipation while avoiding the increase in material and transportation costs, and will not sacrifice the flexibility of the cable.

[0008] The technical solution used in the present invention is: a cable with an air-cooled heat-conducting and heat-dissipating structure, including a cable and an air-cooling control device; one end of the cable is connected to the power supply end, and the other end of the cable is connected to the power consumption end; the air-cooling control device is detachably arranged at one end or the other end of the cable.

[0009] Furthermore, the cable includes a cable shell, an shell cavity, a cable inner shell, an inner shell cavity, a live wire cable, a neutral wire cable and an air-cooling structure; the cable shell includes a cavity opening; the live wire cable and the neutral wire cable are arranged inside the cable inner shell; the cable inner shell is arranged inside the cable shell; the shell cavity is between the cable shell and the cable inner shell; the inner shell cavity is between the cable inner shell and the live wire cable, and between the cable inner shell and the neutral wire cable; the shell cavity and the inner shell cavity are filled with solid insulating material; the air-cooling structure includes a chamber, a cavity tube and a cavity divider; the chamber is divided into several small chambers by the cavity divider; the chamber is tightly wrapped around the outside of the cable inner shell; in any of the several small chambers, one end of several cavity tubes is connected to the small chamber at the same distance, and the other end of the several cavity tubes is connected to the cavity opening, and the cavity tube passes through the cable shell at an inclined angle.

[0010] Furthermore, the lumen is arranged on the cable at a certain slope.

[0011] Furthermore, the chamber is composed of heat-absorbing hard material.

[0012] Furthermore, the chamber is made of flexible material.

[0013] Furthermore, the air cooling control device includes an AC / DCD unit and a motor unit; the input end of the AC / DCD unit is connected to the live wire, and the output end of the AC / DCD unit is connected to the motor unit.

[0014] Furthermore, the power output module of the motor unit is connected to the plurality of small chambers.

[0015] Furthermore, the power output module includes fan blades and air vent holes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1) Excellent heat dissipation efficiency. By combining the air-cooling structure with the active air-cooling control device, the chamber is close to the live cable, the small chamber accurately distributes the airflow, and the heat-absorbing material and the inclined cavity tube design are used to achieve rapid heat conduction and discharge, dynamically matching the heating requirements of the cable. 2) High safety. The double-layer shell and solid insulation material form double protection. The AC / DC conversion reduces the risk of motor power supply. The air cooling and insulation functions are independently set to ensure electrical isolation and enhance heat dissipation, reducing insulation aging problems caused by overheating. 3) Strong practicality.

It is linked to the working status of the cable through the live wire to adapt to complex installation environments and dynamic load changes. 4) Good economy. The modular design reduces maintenance and upgrade costs, precise heat dissipation reduces energy consumption, extends the service life of the cable, and improves the overall life cycle cost-effectiveness.

[0026] 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.

[0027] 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. The present invention will be described in detail below with reference to the accompanying drawings: A cable with an air-cooled heat-conducting and heat-dissipating structure, such as Figure 1 As shown, it includes a cable 100 and an air cooling control device 200.

[0028] One end of the cable 100 is connected to the power supply end, and the other end of the cable 100 is connected to the power consumption end.

[0029] The air cooling control device 200 is detachably disposed at one end or the other end of the cable 100 .

[0030] It should be noted that the air cooling control device 200 is mainly used to promote air cooling and heat dissipation of the cable 100 .

[0031] like Figure 3 As shown, the cable 100 includes: a cable outer shell 101, an outer shell cavity 1011, a cable inner shell 102, an inner shell cavity 1021, a live wire cable 103, a neutral wire cable 104 and an air-cooling structure 105.

[0032] The cable housing 101 includes a cavity 1012 .

[0033] The live cable 103 and the neutral cable 104 are arranged inside the cable inner shell 102 .

[0034] The cable inner shell 102 is disposed inside the cable outer shell 101 .

[0035] The housing cavity 1011 is between the cable outer housing 101 and the cable inner housing 102 .

[0036] The inner shell cavity 1021 is between the cable inner shell 102 and the live cable 103 , and between the cable inner shell 102 and the neutral cable 104 .

[0037] The outer shell cavity 1011 and the inner shell cavity 1021 are filled with solid insulating material.

[0038] The air-cooling structure 105 includes a chamber 1051 , a cavity tube 1052 and a cavity partition 1053 .

[0039] The chamber 1051 is divided into several small chambers by the chamber dividing body 1053 .

[0040] The chamber 1051 is tightly wrapped around the outside of the cable inner shell 102 .

[0041] In any of the several small chambers, one end of several lumens 1052 is connected to the small chamber at the same interval, and the other end of the several lumens 1052 is connected to the cavity opening 1012, and the lumens 1052 pass through the cable housing 101 at an inclined angle.

[0042] It is understandable that the lumen 1052 is provided on the cable 100 at a certain slope to facilitate the entry and removal of air.

[0043] It should be noted that the chamber 1051 is made of heat-absorbing hard material.

[0044] It should be noted that the chamber 1052 is made of flexible material.

[0045] It is understandable that cavity divider 1053 divides chamber 1051 into several smaller chambers. This design is not simply a structural division, but rather a targeted optimization based on the heat generation characteristics of FireWire cable 103. Since different areas of the FireWire cable 103 generate different amounts of heat when powered, localized overheating is very likely to occur, especially when the current load fluctuates significantly. This difference in heat distribution is particularly pronounced when heat is fed back to the cable inner shell 102. By dividing the chambers into smaller chambers, cool air can flow evenly through areas with more concentrated heat, ensuring that each area receives balanced heat dissipation resources. Furthermore, this segmented structure effectively prevents overall heat dissipation failure caused by localized blockage in a single chamber. Even if the airflow circulation in one chamber is affected, the other chambers can still maintain normal heat dissipation, significantly improving the reliability of the air cooling system. Furthermore, the independent spaces within the chambers reduce air turbulence within the chamber, allowing cool air to efficiently flow across the cable surface along a pre-set path, removing as much heat as possible. This significantly reduces the operating temperature of FireWire cable 103 and extends its service life.

[0046] It's understandable that the design of connecting the lumens 1052 to the small chambers at equal spacing reflects a deep consideration of the scientific nature of airflow distribution. In an air-cooled heat dissipation system, the uniformity of airflow directly determines the stability of the heat dissipation effect. If the connection spacing of the lumens 1052 is inconsistent, it will lead to excessive air intake in some areas, resulting in airflow waste, while insufficient air intake in other areas will result in heat dissipation blind spots, ultimately causing uneven surface temperature distribution of the FireWire cable 103. A design with equal spacing ensures that each small chamber receives an equal amount of cold air, maintaining consistent cooling intensity across all heat dissipation areas. From a fluid mechanics perspective, the evenly distributed lumens 1052 also reduce resistance to airflow during diversion, minimizing energy loss and allowing cold air to enter the chamber 1051 more efficiently. Furthermore, this standardized spacing design facilitates the industrial production of cables, facilitating standardized operations in mold manufacturing and assembly processes, reducing the impact of production errors on heat dissipation performance, and providing a unified reference standard for subsequent maintenance and repair, improving the overall practicality and cost-effectiveness of the cable.

[0047] It is understandable that the chamber 1051 uses a heat-absorbing hard material, which is a deep enhancement of the heat dissipation function. The heat-absorbing material itself has a high heat absorption rate and heat storage capacity, which can quickly absorb the heat emitted by the live cable 103, forming a heat accumulation area in the chamber, and reserving heat sources for subsequent heat exchange with cold air. The rigid properties ensure that the material fits tightly to the surface of the cable, avoids heat transfer losses caused by gaps, and ensures efficient conduction of heat from the cable to the chamber. This material selection allows the chamber 1051 to have both "heat absorption" and "heat transfer" functions: on the one hand, it quickly responds to the temperature changes of the cable through the heat absorption characteristics, absorbs excess heat in time, and prevents local temperature rises; on the other hand, with the help of the stability of the rigid structure, it maintains continuous contact with the cable and stably transfers the stored heat to the cold air flowing through the chamber. Compared with ordinary rigid materials, heat-absorbing rigid materials can take away more heat in the same period of time. Especially in scenarios where the cable load suddenly increases and the heat generation increases sharply, they can quickly buffer temperature fluctuations, buy time for the air cooling system to dissipate heat, and significantly improve the thermal stability and safety redundancy of the cable.

[0048] It is understood that the lumen 1052 is made of a flexible material to accommodate the cable's complex internal structure and dynamic changes during actual use. The space between the cable inner shell 102 and the cable outer shell 101 is filled with solid insulating material, through which the lumen 1052 must pass to connect with the cavity 1012. The flexible material, through its inherent deformability, can flexibly adapt to the filling density and structural distribution of the insulating material, avoiding squeezing or damage to the insulating material during installation, thereby ensuring the integrity and insulation performance of the insulation layer. During actual cable use, bending and twisting may be necessary due to installation environment constraints. The flexible lumen 1052 can bend synchronously with the cable's deformation, eliminating the breakage or sealing failure that can occur with rigid materials, ensuring a continuously unobstructed airflow channel. Furthermore, the flexible material is relatively soft, allowing for a tighter fit at the connection between the chamber 1051 and the cavity 1012 through elastic deformation, reducing air leakage and improving heat dissipation efficiency. Furthermore, the flexible material is relatively lightweight, not significantly increasing the overall weight of the cable, facilitating cable transportation and installation.

[0049] It can be understood that the double-layer structure formed by the cable outer shell 101 and the cable inner shell 102, combined with the solid insulation material filled between them, creates a highly effective dual-protection system. From an electrical safety perspective, the combination of the double-layer shell and the solid insulation material significantly improves the cable's insulation level. Even if one shell or insulation layer is damaged and its insulation performance degrades, the other layer still provides protection, significantly reducing the risk of leakage. From a mechanical protection perspective, the outer shell 101 directly protects against physical damage from external friction, impact, and other physical damage, while the inner shell 102 further buffers external forces, protecting the live and neutral cables 103 and 104 from mechanical stress. Furthermore, the solid insulation material fills the gap between the shell and the cable during the filling process, forming a uniform support structure that prevents wear and tear on the cable due to shaking within the shell, thereby extending the cable's service life. Furthermore, the double-layer shell structure reduces the impact of external temperature fluctuations on the internal cable, providing a relatively stable operating environment for the cable and helping to maintain its electrical performance.

[0050] It can be understood that the independent setting of the air-cooling structure 105 and the solid insulating material achieves the coordinated optimization of the heat dissipation function and the insulation function. The main function of the solid insulating material is to block the current conduction path, ensure the electrical isolation between the live cable 103 and the neutral cable 104, and between the cable and the external environment, and its material properties focus more on insulation resistance and electrical strength. The core function of the air-cooling structure 105 is to carry away the heat accumulated in the cable inner shell 102 through air flow, and its structural design focuses on improving the heat exchange efficiency. Setting the two independently can avoid the thermal resistance characteristics of the insulating material affecting the heat dissipation effect, and at the same time prevent the air flow channel of the air-cooling structure from damaging the integrity of the insulating material. This design allows the two functions to be optimized according to their own needs: the insulating material can be selected from a material with low thermal conductivity but excellent insulation performance to ensure electrical safety; the air-cooling structure can improve the heat dissipation efficiency by optimizing the cavity shape, cavity tube layout, etc., without considering the impact on insulation performance. In addition, the independent setting also facilitates subsequent maintenance and upgrades. When the heat dissipation performance needs to be improved, only the air-cooling structure can be improved without replacing the insulation material, and vice versa, which greatly improves the flexibility and economy of the cable structure.

[0051] It is understandable that the design of the lumen 1052 passing through the cable inner shell 102 and the cable outer shell 101 at an inclined angle fully utilizes the physical properties of air convection and significantly improves the heat dissipation efficiency. Under natural convection, hot air will flow upward due to its lower density, while cold air will flow downward due to its higher density, forming a cycle. The inclined setting of the lumen 1052 can conform to this natural convection trend, allowing the heated air in the chamber 1051 to flow more smoothly along the inclined direction to the cavity opening 1012 for discharge or squeeze in. At the same time, the external cold air can also enter the chamber more efficiently along the inclined path, forming a continuous airflow cycle. Compared with vertical or horizontal lumen settings, the inclined angle design can shorten the exhaust speed of hot air and reduce the residence time of airflow in the lumen. In addition, the inclined passage method can also reduce the contact length of the lumen with the inner and outer shells and insulating materials, reducing the risk of damage to the lumen due to friction or extrusion. It can also reduce the internal space occupied by the lumen, leaving more room for the layout of other components. From the installation perspective, the inclined setting can also reduce the cross-interference between the cavity tube and the solid insulating material during the insertion process, facilitate the reasonable layout of the cavity tube in the limited cavity space, ensure that the insulating material can be fully filled, and do not affect the overall insulation performance.

[0052] It is understandable that the design of the chamber 1051 tightly wrapped around the outside of the cable inner shell 102 is a key link in achieving efficient heat dissipation. The efficiency of heat transfer is closely related to the contact area and the degree of contact tightness. The close contact between the chamber 1051 and the cable inner shell 102 can maximize the heat exchange area between the two, so that the heat generated by the cable can be directly transferred to the inner wall of the chamber 1051 and then carried away by the flowing air in the chamber. If there is a gap between the two, the thermal conductivity of the air is low, which will form a large thermal resistance and significantly reduce the heat dissipation efficiency. In addition, the tightly wrapped design can also reduce the impact of external factors on the contact state between the chamber and the cable. Even in the case of cable vibration or slight deformation, it can still maintain good contact to ensure the continuity and stability of heat transfer. From the perspective of structural mechanics, this wrapping method can also form a certain restraining effect on the FireWire cable 103, reduce the shaking of the cable during operation, reduce the loss caused by friction, and at the same time avoid damage to the internal conductor caused by excessive bending of the cable, thereby extending the service life of the cable.

[0053] like Figure 2 As shown, the air cooling control device includes an AC / DCD unit 201 and a motor unit 202 .

[0054] An input end of the AC / DCD unit 201 is connected to the live wire 103 , and an output end of the AC / DCD unit 201 is connected to the motor unit 202 .

[0055] It should be noted that the power output module of the motor unit 202 is connected to the plurality of small chambers.

[0056] It should be noted that the power output module includes fan blades and air vents.

[0057] It is understandable that the AC / DC unit 201 draws power directly from the FireWire cable 103 without the need for an additional external power supply. This design greatly simplifies the installation and use process of the air-cooling control device. The FireWire cable 103, as the core conductive component of the cable, has a continuous current flowing through it. The AC / DC unit 201 uses this as a power source, which can ensure that the device starts synchronously when the cable is working, achieving the linkage effect of "heat dissipation starts when the cable is powered on", and saves the cost and space of laying independent power supply lines. It is especially suitable for use in scenarios with limited space or complex wiring. At the same time, this power-drawing method can make the operating status of the air-cooling system highly bound to the working status of the cable, avoiding the disconnection situation of "the cable is working but the heat dissipation device is not started", and ensuring the timeliness of heat dissipation from the source.

[0058] It is understandable that the power output module of the motor unit 202 includes fan blades and air vents, which are key designs for precise control of the air-cooling airflow. As an active air supply component, the fan blades can generate directional airflow through rotation to solve the problem of insufficient natural convection efficiency, especially when the internal structure of the cable is complex and the airflow resistance is large. The wind pressure can be increased to ensure that the cold air reaches the chamber 1051 efficiently; and the air vents play the role of airflow guidance and diversion, which can evenly distribute the airflow generated by the fan blades to each small chamber, avoid local excess or insufficient airflow, and ensure balanced heat dissipation in each area of ​​the live cable 103. The combination of the two allows the air cooling system to be upgraded from "passive heat dissipation" to "active and controllable heat dissipation", which can adjust the wind speed and air volume according to the heating conditions of the cable, greatly improving the pertinence and efficiency of heat dissipation.

[0059] It is understandable that the power output module is connected to several small chambers, which means that each small chamber can obtain an independent and controllable airflow supply. This "one-to-one" or "group-corresponding" connection method can accurately dissipate heat according to the heat differences in the areas covered by different small chambers. For example, when a certain section of the live cable 103 is more heated due to a high load, the power output module connected to the corresponding small chamber can be adjusted by adding a main control unit and a temperature sensor to increase the air volume in that area, realizing dynamic regulation of "enhancing heat dissipation in areas with overheating", avoiding energy waste caused by blind overall air supply, while maximizing the local heat dissipation effect and making cable temperature control more refined.

[0060] It is understandable that the air-cooling control device has built a self-sufficient closed-loop heat dissipation system through a complete link of live wire power supply, AC / DC conversion, motor drive, and airflow circulation. This system does not need to rely on an external independent power supply, which reduces the need for additional wiring and makes the overall structure of the cable simpler. Especially in complex environments such as outdoors and underground, it can reduce installation difficulty and maintenance costs. At the same time, the closed-loop design allows the heat dissipation process to be completely controlled by the working state of the cable itself, forming an instant response from power input to heat dissipation execution, ensuring that heat generation and heat dissipation are synchronized. This highly integrated design not only retains the advantage of high air-cooling heat dissipation efficiency, but also reduces human intervention through automated control, so that the cable can maintain a stable temperature under various working conditions, providing a solid guarantee for the safety and durability of power transmission.

[0061] It is understandable that the air cooling control device 100 forms an air cooling system through such a connection method. Figure 2 As shown, the AC / DC unit 201 can convert the AC power transmitted by the live cable 103 into DC power, providing appropriate power for the motor unit 202. When the cable 100 is powered on, the air cooling control device 100 receives power input, and the motor unit 202 starts working.

[0062] It is understandable that if Figure 4 As shown, when the motor unit 202 is working, it can promote the cold air from the outside to flow along the cavity 1012, the cavity tube 1052, the cavity 1051 and the air vent hole according to the predetermined flow path, thereby accelerating the transfer and dissipation of heat, ensuring that the temperature of the sealed cable 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 working condition changes.

[0063] It is understandable that if Figure 5 As shown, when the motor unit 202 is working, it can promote the cold air from the outside to flow along the air vent hole, the chamber 1051, the cavity tube 1052 and the cavity opening 1012 according to the predetermined flow path, thereby accelerating the transfer and dissipation of heat, ensuring that the temperature of the sealed cable 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 working condition changes.

[0064] It can be understood that the setting of the air cooling control device 200, without the need for additional power supply, enables the cold air from the outside to cool the live wire cable 103 inside the cable through the air cooling structure 105 through the live wire and neutral wire of the cable itself, and the cooling effect is efficient and low-cost.
