[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-4 In this embodiment of the invention, the high-temperature resistant wire and cable includes a cable body, which includes an inner core and an outer protective layer 6. The inner core includes a conductive core 1, and the outer wall of the conductive core 1 is covered with an insulation layer 2. The outer wall of the insulation layer 2 consists of a polyimide composite film, a glass fiber cloth 3, a glass fiber braided layer 4, a mica wrapping layer, and a sealing layer 5, arranged from the inside out. By setting the glass fiber cloth 3 and the glass fiber braided layer 4, the high-temperature resistance of the cable is improved. By setting the sealing layer 5, water and air flow are prevented from entering the inner core of the cable, ensuring the cable's airtightness.

[0026] A heat dissipation cavity is provided between the outer protective layer 6 and the inner core of the cable. Several equally spaced partition gaskets 7 are fixedly connected to the inner wall of the heat dissipation cavity, dividing the heat dissipation cavity into several cooling chambers 11.

[0027] The heat dissipation cavity is divided into several cooling chambers 11 for supplying cooling medium by setting several partition gaskets 7. The cooling medium is circulated in the chambers to cool the cable, thereby improving the cable's high temperature resistance.

[0028] Each of the several separating gaskets 7 has a connecting cavity 12 at its bottom, and both ends of the several connecting cavities 12 are connected to the cooling cavity 11. By setting the connecting cavity 12, the cooling cavities 11 are connected to each other, so that the cooling contact can be evenly distributed and flowed inside the cable body, ensuring uniform heat dissipation.

[0029] A cooling component for supplying cooling medium is fixedly connected to the top of the outer protective layer 6. The cooling component includes a cooling guide plate 13, and an inlet pipe 14 and an outlet pipe 15 are fixedly connected to the bottom of the cooling guide plate 13. An inlet and an outlet are provided on one side of the cooling guide plate 13. The inlet pipe 14 is fixedly connected to the inlet, and the outlet pipe 15 is fixedly connected to the outlet. Sealing gaskets are fixedly connected to the inner walls of both the inlet and outlet. Cooling circulation pipes 30 are engaged with the inner walls of both sealing gaskets. The cooling circulation pipes 30 are connected to the refrigeration mechanism. By setting up the cooling component, the cooling medium is circulated into the cooling chamber 11 in cooperation with the refrigeration mechanism to achieve continuous cooling of the cable.

[0030] The inlet pipe 14 and the outlet pipe 15 extend into the same cooling chamber 11, and the inlet pipe 14 is fixedly connected to one end of the connecting chamber 12; in this way, the incoming cooling medium can circulate along each cooling chamber 11 and then be discharged from the outlet pipe 15, thus ensuring the cooling effect of the cooling medium.

[0031] To improve the heat dissipation capacity of the cable and the cooling capacity of the cooling medium, heat dissipation ducts 8 are embedded in the top of several partition gaskets 7. One end of the cable body is provided with an air supply device for supplying airflow into the heat dissipation ducts 8. The air supply device includes an air supply frame 17. Several equally spaced air supply connectors are fixedly installed on the inner wall of the air supply frame 17. The air supply connectors include air guide shrouds 21. One end of the air guide shroud 21 is fixedly connected to a connecting pipe 24 by a spring. The ends of several heat dissipation ducts 8 near the air supply device are provided with connecting holes. Several connecting pipes 24 are respectively engaged with several connecting holes. A distribution plate 19 is fixedly connected to the top of the inner wall of the air supply frame 17. Several distribution air pipes 23 are fixedly connected to the bottom of the distribution plate 19. Several distribution air pipes 23 are respectively fixedly connected to the middle of several air guide shrouds 21. An air inlet pipe 20 is fixedly connected to the top of the distribution plate 19. One end of the air inlet pipe 20 is fixedly connected to the output end of an external air pump. By setting up an air supply device, several air supply connectors are used to supply air to several heat dissipation ducts 8 respectively, making the air supply heat dissipation more uniform.

[0032] A pressure sensor 22 is fixedly installed at one end of the inner wall of the air guide shroud 21. A sliding plate 25 is provided on one side of the pressure sensor 22. The sliding plate 25 is slidably connected to the inner wall of the air guide shroud 21. A pressure rod is fixedly connected to one side of the sliding plate 25. A return spring is fixedly connected between the sliding plate 25 and the end of the inner wall of the air guide shroud 21. By setting up the pressure sensor 22 and other structures, the air pressure of the airflow sent into each heat dissipation duct 8 is detected, so as to realize the judgment of the conduction status of each heat dissipation duct 8. When the cable is twisted or squeezed, the gas resistance of the corresponding compressed heat dissipation duct 8 increases, which in turn increases the air pressure inside the corresponding air guide shroud 21. The detection of the cable laying status is realized in conjunction with the detection of the pressure sensor 22.

[0033] Several heat pipes 8 have extensions 9 fixedly connected to both sides. By setting the extensions 9, the area of ​​the heat pipes 8 is increased, and the heat dissipation effect is improved.

[0034] Limiting grooves are provided between two adjacent extensions 9. Several reinforcing rings 10 are slidably connected to the outer wall of the cable body. Several limiting blocks are fixedly connected to the inner wall of the reinforcing rings 10. The limiting blocks are slidably connected to the limiting grooves. By setting the reinforcing rings 10, the cable exterior is protected and supported, and the structural strength of the cable is improved.

[0035] The outer wall of the reinforcing ring 10 is provided with several equally spaced snap-fit ​​grooves. The inner wall of the snap-fit ​​grooves is engaged with a push block 16. Both sides of the push block 16 are set as bevels. By setting the snap-fit ​​grooves and engaging with the push block 16, the posture of the cable is limited, so as to avoid damage caused by excessive twisting of the cable during installation and use.

[0036] This application also includes a refrigeration mechanism, which includes a refrigeration box 26. Several refrigeration units are equidistantly arranged on the inner wall of the refrigeration box 26. Each refrigeration unit includes a reflux heat sink 27, and a reflux cavity is formed on the inner wall of the reflux heat sink 27. One end of the reflux cavity is fixedly connected to a cooling circulation pipe 30. A circulating water pump is fixedly installed at one end of the refrigeration box 26. The output and input ends of the circulating water pump are respectively connected to two cooling circulation pipes 30. Several heat sinks 28 are fixedly connected to both sides of the reflux heat sink 27, and a cooling fan 29 is fixedly installed between two reflux heat sinks 27. By setting up the reflux heat sink 27 and the heat sinks 28, and cooperating with the fan to blow heat onto the heat sinks 28 to cool them down, the heat dissipation medium is sufficiently cooled.

[0037] A support platform 18 is fixedly connected to the bottom of the inner wall of the air supply frame 17. A support groove is opened on the top of the support platform 18. Several support positioning blocks are fixedly connected to the inner wall of the support groove. The several support positioning blocks are respectively set with several limiting grooves to improve the positional stability of the cable when it is sent into the air supply device.

[0038] When in use, the invention is started by a circulating water pump, which drives the water flow. The water is sent into the cooling guide plate 13 through the cooling circulation pipe 30, and then into the connecting cavity 12 through the inlet pipe 14. It flows along each cooling cavity 11 and flows back to the outlet pipe 15 for discharge. The water is circulated through the cooling circulation pipe 30 to cool the cable. At the same time, the cooling fan 29 is started to dissipate heat from each heat sink 28, thereby reducing the water temperature and ensuring the heat dissipation effect.

[0039] The air is started by an external air pump, and air is introduced through the air inlet pipe 20. After being diverted by the diversion pipe, the air is sent to each air guide hood through each diversion pipe 23, and then sent to each heat dissipation duct 8 through the connecting pipe 24. This allows for ventilation and heat dissipation of each heat dissipation duct 8, thereby improving the heat resistance of the cable.
