[0061] In the description of the present application, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0062] Next, the cable flow channel pipe 2 and the cable 100 of some embodiments of the present application will be described. Figures 1-8 The cable flow channel pipe 2 and the cable 100 of some embodiments of the present application will be described.

[0063] Referring to Figures 1-6 The embodiments of the first aspect of the present application provide a cable flow channel pipe 2 for containing a working medium and a conductive core, the cable flow channel pipe 2 comprising a pipe body 21 and a support structure 22, the support structure 22 being provided on the inner wall surface of the pipe body 21, for example, the support structure 22 being protruded on the inner wall surface of the pipe body 21, the support structure 22 being adapted to define a gap with the conductive core 3 to form a flow passage 8 for the working medium to flow.

[0064] The working medium contained in the cable flow channel pipe 2 can be used to adjust the temperature of the cable flow channel pipe 2, for example, to heat or cool the cable flow channel pipe.

[0065] The support structure 22 is adapted to define a gap with the conductive core 3 in the pipe body 21, the gap forming a flow passage 8 for the working medium to flow, allowing the working medium to flow in the pipe body 21 through the gap, thereby realizing heat exchange between the working medium and the conductive core 3. The working medium can flow freely in the flow passage 8, which helps to improve the heat transfer efficiency.

[0066] The conductive core 3 is actually used for current transmission in the cable 100, and the working state of the conductive core 3 has a great influence on the use performance of the cable 100. The conductive core 3 is accommodated in the cable flow channel pipe 2, so that the working medium accommodated in the cable flow channel pipe 2 can adjust the temperature of the conductive core 3, so that the conductive core 3 is in a good working state, thereby improving the use performance of the cable 100.

[0067] Optionally, the working medium can be a refrigerant for refrigeration or heating adjustment of the cable flow channel pipe; the working medium can also be a cooling medium which can take away the heat of the conductive core through heat exchange with the conductive core. For example, the cooling medium can be a fluid such as a liquid or a gas, and the working medium is an insulating medium. Specifically, the working medium can be a cooling liquid, for example, the cooling liquid can be insulating oil, fluorinated liquid or deionized water (completely pure water).

[0068] When the cable flow channel pipe 2 is bent or extruded under force, the support structure 22 is beneficial to improve the strength of the cable flow channel pipe 2 to reduce the deformation degree of the cable flow channel pipe 2, so that the change degree of the size of the gap between the conductive core 3 and the support structure 22 is also reduced, thereby reducing the influence of the change of the size of the gap on the flowability of the working medium in the cable flow channel pipe 2.

[0069] In addition, when the cable flow channel pipe 2 is bent or extruded under force, the support structure 22 is supported on the conductive core 3, and the gap between the conductive core 3 and the support structure 22 will not be completely blocked due to the support of the support structure 22, which is also beneficial to further improve the flowability of the working medium in the cable flow channel pipe 2 which is bent or extruded.

[0070] All of these make the flowability of the working medium in the cable flow channel pipe 2 good when the cable flow channel pipe 2 is bent or extruded under force, so that the working medium can effectively exchange heat with the conductive core 3, and the problem of poor temperature adjustment effect of the cable 100 can be effectively improved. For example, the flowability of the working medium in the cable flow channel pipe 2 is good, so that the working medium can effectively dissipate heat from the conductive core 3, and the problem of poor heat dissipation effect of the cable 100 can be effectively improved.

[0071] Optionally, the support structure 22 can be a continuous structure along the extension direction of the cable flow channel pipe 2, and the support structure 22 can also be a structure arranged discontinuously along the extension direction of the cable flow channel pipe 2.

[0072] For example, in the manufacturing process of the cable flow channel pipe 2, the support structure 22 can be integrally formed on the pipe body 21, which is beneficial to simplify the production process of the cable flow channel pipe 2.

[0073] For example, in the manufacturing process of the cable flow channel pipe 2, the support structure 22 can also be detachably arranged on the pipe body 21, which is convenient for maintenance and replacement of the pipe body 21 and the support structure 22.

[0074] According to the cable flow channel pipe 2 in the embodiment of the utility model, the support structure 22 is arranged, when the cable flow channel pipe 2 is bent or extruded, the support structure 22 is favorable to improve the strength of the cable flow channel pipe 2 to reduce the deformation degree of the cable flow channel pipe 2, when the support structure 22 is stressed and supported on the conductive core 3, the gap between the conductive core 3 and the support structure 22 is not completely blocked due to the support of the support structure 22, which is favorable to improve the flowability of the working medium in the cable flow channel pipe 2 that is bent or extruded, so that the working medium can exchange heat with the conductive core 3 effectively, and the problem that the temperature regulation effect of the cable 100 is poor can be effectively improved, in addition, the support structure 22 can also improve the anti-rolling pressure capacity of the cable flow channel pipe.

[0075] Reference Figures 3-7 In some embodiments, the support structure 22 includes a plurality of support ribs 221 arranged circumferentially along the inner wall of the pipe body 21, and at least a partial flow passage is defined between adjacent two support ribs 221. For example, the support ribs 221 are three, and the three support ribs 221 are uniformly and circumferentially distributed along the pipe body 21; for example, the support ribs 221 are four, and the four support ribs 221 are uniformly and circumferentially distributed along the pipe body 21.

[0076] Among them, the at least partial flow passage defined between adjacent two support ribs 221 can include the following cases: for example, the surface of the support rib 221 facing the conductive core 3 is adapted to contact the conductive core 3, the gap between the conductive core 3 and the support structure 22 includes the gap between adjacent two support ribs 221, and the gap between adjacent two support ribs 221 forms the flow passage 8.

[0077] For another example, the surface of the support rib 221 facing the conductive core 3 is adapted to define a partial gap with the conductive core 3, the gap between the conductive core 3 and the support structure 22 includes the gap between adjacent two support ribs 221 and the gap between the surface of the support rib 221 facing the conductive core 3 and the conductive core 3, and the gap between adjacent two support ribs 221 forms the partial flow passage 8.

[0078] The support ribs 221 are arranged circumferentially along the pipe body 21, and the gap between adjacent two support ribs 221 makes the support structure 22 not excessively hinder the flow of the working medium. The gap between adjacent support ribs 221 forms the flow passage 8 of the working medium, and the support rib 221 can guide the working medium to flow along a predetermined path, ensure that the working medium can form an effective circulation around the conductive core 3, reduce or avoid the occurrence of dead angles or turbulent flow, and improve the consistency of heat exchange effects such as heating or heat dissipation.

[0079] Reference Figure 6In some embodiments, the diameter of the space surrounded by the plurality of support ribs 221 away from the surface of the tube body 21 is greater than the diameter of the conductive core 3. By making the diameter of the space surrounded by the plurality of support ribs 221 away from the surface of the tube body 21 greater than the diameter of the conductive core 3, an additional space can be formed around the conductive core 3, which is part of the gap between the conductive core 3 and the support structure 22, as the flow channel 8 of the working medium, increasing the contact area between the working medium and the conductive core 3, thereby improving the heat exchange efficiency.

[0080] With reference to Figure 2 In some embodiments, the tube body 21 and the support structure 22 are integrally formed. By integrally forming the tube body 21 and the support structure 22, the cable flow channel tube 2 is easy to form, and the integrally formed design ensures the material continuity between the tube body 21 and the support structure 22, which can reduce or avoid local stress concentration, thereby improving the service life of the cable flow channel tube 2.

[0081] With reference to Figure 2 In some embodiments, the support structure 22 is annularly arranged on the outer peripheral side of the conductive core 3. Optionally, at least part of the support structure 22 is adapted to define a gap with the outer peripheral surface of the conductive core 3. For example, the support structure 22 can be formed as a continuous wave-shaped structure annularly arranged on the outer peripheral side of the conductive core 3, and the surface of the support structure 22 facing the conductive core 3 has different distances from the conductive core 3 to form the gap between the conductive core 3 and the support structure 22.

[0082] By annularly arranging the support structure 22 on the outer peripheral side of the conductive core 3, the gap between the conductive core 3 and the support structure 22 will not be completely blocked due to the supporting effect of the support structure 22 when the cable 100 is bent or squeezed in any direction, thereby effectively avoiding the problem of poor flowability of the working medium in the cable flow channel tube 2, and further improving the stability and reliability of the heat exchange effect of the cable flow channel tube 2. In addition, annularly arranging the support structure 22 on the outer peripheral side of the conductive core 3 can effectively prevent the conductive core 3 from moving or deforming randomly in the cable flow channel tube 2, ensuring that it can remain stable under various working conditions.

[0083] With reference to Figures 4-6 In some embodiments, the tube body 21 includes a first body portion 211 and a first connecting portion 212 connected to each other, and the first connecting portion 212 is located at at least one end of the first body portion 211 in the extension direction of the cable flow channel tube 2, and the support structure 22 is protruded on the inner wall surface of the first body portion 211. The position of the first connecting portion 212 is not provided with the support structure 22, so that the wall thickness of the first connecting portion 212 is uniform, which is convenient for the cable flow channel tube 2 to be electrically connected to other components through the first connecting portion 212, and is conducive to improving the sealing performance and connection reliability of the entire system.

[0084] The first connecting portion 212 is located at at least one end of the first main body portion 211 along the extension direction of the cable flow channel pipe 2, which can include the following cases: for example, the first connecting portion 212 is located at either end of the first main body portion 211 along the extension direction of the cable flow channel pipe 2; for example, the first connecting portion 212 is located at both ends of the first main body portion 211 along the extension direction of the cable flow channel pipe 2.

[0085] Reference Figure 5 In some embodiments, the support structure 22 includes an intermediate section 222 and a transition section 223, the transition section 223 is arranged at at least one end of the intermediate section 222, and the transition section 223 connects one end of the intermediate section 222 to the end of the transition section 223 away from the intermediate section 222, and the protruding height of the transition section 223 continuously changes. For example, the protruding height of the transition section 223 continuously increases or continuously decreases. The cross-sectional structure of the cable flow channel pipe 2 changes from the first main body portion 211 to the first connecting portion 212, and by arranging the transition section 223, the stress at the cross-sectional change can be relieved.

[0086] Optionally, the protruding height of the transition section 223 from the end of the intermediate section 222 connected to the transition section 223 to the end of the transition section 223 away from the intermediate section 222 can also be fluctuating.

[0087] Reference Figure 5 In some embodiments, the protruding height of the transition section 223 from the end of the intermediate section 222 connected to the transition section 223 to the end of the transition section 223 away from the intermediate section 222 continuously decreases. The protruding height of the transition section 223 continuously decreases, and the change in the protruding height of the transition section 223 conforms to the cross-sectional change between the first main body portion 211 and the first connecting portion 212, which can further improve the stress distribution at the cross-sectional change.

[0088] Reference Figure 2 The second aspect of the embodiments of the utility model provides a cable 100, the cable 100 includes the cable flow channel pipe 2 and the conductive core 3 described above, the cable flow channel pipe 2 includes pipe main body 21 and support structure 22, support structure 22 is arranged on the inner wall surface of pipe main body 21, and the cable flow channel pipe 22 is used to guide the flow of working medium. The conductive core 3 is at least partially contained in the cable flow channel pipe 2, and the conductive core 3 and the working medium are in thermal contact. At least part of the conductive core 3 and the working medium can be in full contact in the cable flow channel pipe 2 to realize sufficient heat exchange between the conductive core 3 and the working medium. For example, the heat generated by the conductive core 3 during operation can be timely taken away by the flowing working medium to achieve the heat dissipation effect of the cable 100.

[0089] The electrically conductive core 3 is at least partially housed in the cable flow channel pipe 2, which can include the following cases: for example, the electrically conductive core 3 is partially housed in the cable flow channel pipe, and the electrically conductive core 3 partially extends out of the cable flow channel pipe. For another example, the electrically conductive core 3 is entirely housed in the cable flow channel pipe. The electrically conductive core 3 is the part of the cable 100 that actually conducts current, which is usually made of a metal such as copper or aluminum that has good electrical conductivity, and is generally a twisted wire composed of multiple small core wires.

[0090] When the cable 100 is subjected to bending or extrusion, the cable flow channel pipe 2 is subjected to bending or extrusion, and the support structure 22 is beneficial to improve the strength of the cable flow channel pipe 2 to reduce the degree of deformation of the cable flow channel pipe 2, so that the degree of change in the size of the gap between the electrically conductive core 3 and the support structure 22 is also reduced, thereby facilitating the reduction of the influence of the change in the size of the gap on the flowability of the working medium in the cable flow channel pipe 2.

[0091] In addition, when the cable 100 is subjected to bending or extrusion, the support structure of the cable flow channel pipe 2 is subjected to stress and supports the electrically conductive core 3, which also causes the gap between the electrically conductive core 3 and the support structure 22 to not be completely blocked due to the support of the support structure 22, which is also beneficial to further improve the flowability of the working medium in the cable flow channel pipe 2 that is subjected to bending or extrusion.

[0092] All of this makes the flowability of the working medium in the cable flow channel pipe 2 good when the cable 100 is subjected to bending or extrusion, so that the working medium can effectively exchange heat with the electrically conductive core 3, thereby effectively improving the problem of poor temperature regulation effect of the cable 100. For example, the flowability of the working medium in the cable flow channel pipe 2 is good, so that the working medium can effectively dissipate heat from the electrically conductive core 3, thereby effectively improving the problem of poor heat dissipation effect of the cable 100.

[0093] Exemplarily, the cable 100 is a charging cable 100 that can be used to charge a vehicle. During the charging process, heat is generated when current passes through the electrically conductive core 3, and these heat is quickly transferred to the surrounding working medium. The working medium exchanges heat with the electrically conductive core 3 during the flow through the cable flow channel pipe 2 to absorb the heat and carry it away, thereby maintaining the electrically conductive core 3 at a lower operating temperature and reducing the increase in resistance and potential safety risks due to overheating.

[0094] According to the cable 100, the cable flow channel pipe 2 is provided, the cable flow channel pipe 2 comprises the support structure 22, when the cable flow channel pipe 2 is bent or extruded under stress, the support structure 22 is beneficial to improve the strength of the cable flow channel pipe 2 to reduce the deformation degree of the cable flow channel pipe 2, and when the support structure 22 is stressed and supported on the conductive core 3, the gap between the conductive core 3 and the support structure 22 is not completely blocked due to the supporting effect of the support structure 22, which is beneficial to improve the flowability of the working medium in the cable flow channel pipe 2 which is bent or extruded, so that the working medium can be effectively exchanged with the conductive core 3, and the problem that the temperature regulation effect of the cable 100 is poor can be effectively improved; in addition, the support structure 22 can also improve the anti-rolling pressure of the cable flow channel pipe.
