Description

Technical Field

[0001] This utility model relates to the technical field of cables, and in particular to a liquid-cooled, bend-resistant cable structure. Background Technology

[0002] Traditional cables are typically designed to meet basic power transmission and signal transmission functions, and their structure is relatively simple, mainly consisting of a conductor, an insulation layer, and a sheath. However, this design has revealed many problems in practical applications.

[0003] First, in scenarios involving frequent bending, the conductors of traditional cables are prone to fracture due to metal fatigue, and the insulation layer is also damaged by wear, leading to short circuits and other problems that severely impact equipment operating efficiency and may cause serious safety hazards. Second, in liquid cooling systems, the coolant pipes of traditional cables are easily flattened or blocked when bent, preventing the coolant from flowing smoothly and significantly reducing heat dissipation. Finally, traditional cables are prone to overheating during high-power transmission, leading to performance degradation or even damage, which in turn affects the stability and lifespan of the equipment. Therefore, there is an urgent need to design a new structure to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a liquid-cooled, bend-resistant cable structure with good bend resistance, strong support, and a long service life even in extreme scenarios.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0006] A liquid-cooled, bend-resistant cable structure includes a conductor assembly comprising three conductors and a conductor sheath layer; the conductor sheath layer wraps around the three conductors and has several capillary tubes along its axial direction; a liquid-cooling assembly is located outside the conductor assembly; the liquid-cooling assembly includes several sets of liquid-cooling pipe components; the liquid-cooling pipe components are arranged around the outside of the conductor assembly; each liquid-cooling pipe component includes a liquid-cooling pipe and a liquid-cooling pipe sheath layer; the liquid-cooling pipe is arranged along the circumference of the conductor sheath layer; and the liquid-cooling pipe sheath layer wraps around the liquid-cooling pipe.

[0007] The outer sheath layer encloses the liquid cooling components.

[0008] Furthermore, the outer side of the liquid cooling pipe is corrugated.

[0009] Furthermore, the cold pipe components are spirally wound around the outside of the conductor sheath layer.

[0010] Furthermore, the conductor sheath layer is provided with several capillary tubes along the axial direction.

[0011] Furthermore, petroleum jelly is filled between the conductor sheath, the liquid cooling pipe sheath, and the outer sheath.

[0012] Furthermore, the three conductors are arranged in a triangular pattern.

[0013] As described above, the liquid-cooled, bend-resistant cable structure of this invention has the following beneficial effects:

[0014] 1. The corrugated pattern on the outside of the liquid cooling pipe sheath, combined with its spiral arrangement on the outside of the conductor sheath, greatly improves the bending resistance of the liquid cooling pipe sheath, preventing it from being bent and blocking the flow of coolant.

[0015] 2. The capillary tube design along the axial direction of the conductor sheath layer greatly improves the support performance of the conductor sheath layer, prevents it from cracking under extreme bending conditions, and improves the safety performance in use. Attached Figure Description

Detailed Implementation

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0021] Please see Figure 1-3It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0022] Please see Figure 1-3 This utility model provides a liquid-cooled, bend-resistant cable structure 100, including a conductor assembly 1, a liquid-cooling assembly 2, and an outer sheath layer 3. The conductor assembly 1 includes three conductors 11 and a conductor sheath layer 12; the conductor sheath layer 12 wraps around the three conductors 11. The liquid-cooling assembly 2 is located outside the conductor assembly 1; the liquid-cooling assembly 2 includes several sets of liquid-cooling pipe components 21; the liquid-cooling pipe components 21 are arranged around the outside of the conductor assembly 1; each liquid-cooling pipe component 21 includes a liquid-cooling pipe 211 and a liquid-cooling pipe sheath layer 212; the liquid-cooling pipe 211 is arranged along the circumference of the conductor sheath layer 12; the liquid-cooling pipe sheath layer 212 wraps around the liquid-cooling pipe 211.

[0023] Furthermore, the outer sheath layer 3 is configured to enclose the liquid cooling component 2.

[0024] In an alternative embodiment, a microchannel radiator can be integrated into the liquid cooling pipe component 21 to increase the turbulence of the coolant, thereby more effectively absorbing and dissipating heat, and thus improving the heat exchange efficiency between the coolant and the wire 11.

[0025] Preferably, the conductor assembly 1, the liquid cooling assembly 2, and the outer sheath layer 3 can all adopt a flexible and flat design to adapt to narrower environments.

[0026] Please continue reading. Figure 1 and Figure 2 The liquid cooling pipe 211 has a corrugated pattern on the outside.

[0027] Specifically, a gentler corrugated pattern can be used in the bending areas of the cable to further improve its bending resistance.

[0028] In this embodiment, as Figure 1 The cold pipe component 21 is spirally wrapped around the outside of the conductor sheath layer 12.

[0029] Preferably, the spiral design of the cold pipe components 21 can be changed to a multi-layer spiral structure, that is, the first layer of cold pipe components 21 surrounds the wire sheath layer 12, and the second layer of cold pipe components 21 surrounds the outside of the first layer of cold pipe components 21, thereby further improving heat dissipation efficiency.

[0030] Please continue reading. Figure 2 and Figure 3 The conductor sheath layer 12 is provided with several capillary tubes 121 along the axial direction.

[0031] In addition, materials such as steel wire can be filled inside the conductor sheath layer 12 to further enhance its lateral strength, thereby indirectly improving the cable's bending resistance.

[0032] like Figure 2 As shown, petroleum jelly is also used to fill the space between the conductor sheath layer 12, the liquid cooling pipe sheath layer 212, and the outer sheath layer 3. Petroleum jelly has a high melting temperature, suitable hardness, viscosity, and good low-temperature toughness; the use of petroleum jelly as a filler can provide good cushioning when the cable is bent, greatly improving the cable's bending resistance.

[0033] In an alternative embodiment, high-strength fibers may be filled between the conductor sheath layer 12, the liquid cooling tube sheath layer 212 and the outer sheath layer 3 as another preferred option to further improve the cable's tensile and compressive strength.

[0034] In this embodiment, as Figure 1 and Figure 2 The three conductors 11 are arranged in a triangular pattern.

[0035] It should be noted that in applications requiring high-power transmission and where reduced inductive reactance is necessary, the three conductors 11 can also be arranged in a straight and close manner to avoid twisting and thus eliminate inductive reactance.

[0036] Please see Figure 1 The outer sheath layer 3 is made of polyethylene. Preferably, the outer sheath layer 3 can also be made of polyurethane, which further improves the abrasion resistance of the cable by increasing production costs.

[0037] The implementation principle of the liquid-cooled bend-resistant cable structure 100 in this utility model is as follows: coolant flows in each liquid-cooling pipe 211, carrying away the heat generated by the conductor 11 for cooling; when bending occurs, the spiral arrangement of the liquid-cooling pipe 211, combined with the support of the surface corrugated texture, and the several capillary tubes 121 of the conductor sheath layer 12 along the axial direction, greatly disperse the force and improve its bend resistance.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
