It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1-Figure 5 The utility model provides a technical solution: a cable with a built-in cooling tube, a signal cable core 3 and a current-carrying cable core 4 are fixed to the inner wall of an outer sheath 1, the signal cable core 3 and the current-carrying cable core 4 are spirally wound on the surface of a cooling tube 5, so that the signal cable core 3 and the current-carrying cable core 4 are separated from the cooling tube 5 to a greater extent, thereby improving the cooling efficiency, and a first through hole 6 is opened on the outer surface of the outer sheath 1, and the first through hole 6 penetrates into the interior of the outer sheath 1.

[0026] Reinforcing ribs 9 are fixed on the outer surface of the cooling tube 5. Due to the requirements of cable application scenarios, the cable is often bent when used. The presence of the reinforcing ribs 9 increases the strength of the cooling tube 5. A tube cavity 8 is opened at the end of the cooling tube 5, and a guide block 10 is fixed on the inner wall of the tube cavity 8. A second through hole 11 is opened on the outer surface of the cooling tube 5, and the second through hole 11 penetrates into the interior of the cooling tube 5.

[0027] On the basis of Example 1, in order to realize automatic cooling of the cable, the cooling tube 5 is fixed inside the outer sheath 1, the signal cable core 3 and the current-carrying cable core 4 are located on the outer surface of the cooling tube 5, the signal cable core 3 and the current-carrying cable core 4 are spirally wound on the outer surface of the cooling tube 5, and the first through hole 6 is provided with a first annular groove 7 on the inner wall.

[0028] A second annular groove 12 is provided on the inner wall of the second through hole 11, and a ventilation pipe 2 is provided on the inner wall of the second through hole 11. The ventilation pipe 2 connects the tube cavity 8 with the outside air, and discharges the heat absorbed in the tube cavity 8 to the outside of the cable through the ventilation pipe 2, thereby realizing automatic cooling of the cable. One end of the ventilation pipe 2 is located on the inner wall of the second through hole 11, and the other end of the ventilation pipe 2 is located on the inner wall of the first through hole 6. An annular block 13 is fixed on the outer surface of the end of the ventilation pipe 2, and the annular block 13 is made of rubber.

[0029] The diameter of the first through hole 6 is the same as that of the vent pipe 2, the diameter of the first annular groove 7 is the same as that of the annular block 13, and the diameter of the first annular groove 7 is larger than the diameter of the first through hole 6, and the annular block 13 corresponds to the first annular groove 7, and the annular block 13 is stuck in the first annular groove 7, and the two are movably connected, so the annular block 13 will not easily fall out of the first annular groove 7, so the vent pipe 2 will not easily fall out of the outer protective layer 1.

[0030] The diameter of the second through hole 11 is the same as that of the ventilation pipe 2, the diameter of the second annular groove 12 is the same as that of the annular block 13, and the diameter of the second annular groove 12 is larger than the diameter of the second through hole 11, and the annular block 13 corresponds to the second annular groove 12, and the annular block 13 is stuck in the second annular groove 12, and the two are movably connected, so the annular block 13 will not easily fall out of the second annular groove 12, so the ventilation pipe 2 will not easily fall out of the cooling pipe 5.

[0031] There are multiple groups of reinforcing ribs 9, which are circumferentially distributed on the outer surface of the cooling tube 5; there are multiple groups of guide blocks 10, which are circumferentially distributed on the inner wall surface of the tube cavity 8, and the guide blocks 10 are spiral.

[0032] There are multiple groups of ventilation pipes 2, which are symmetrically distributed inside the outer sheath 1. One end of the ventilation pipe 2 is connected to the tube cavity 8, and the other end of the ventilation pipe 2 is connected to the outer surface of the outer sheath 1. The ventilation pipe 2 connects the tube cavity 8 with the outside air, and discharges the heat absorbed in the tube cavity 8 to the outside of the cable through the ventilation pipe 2, thereby realizing automatic cooling of the cable.

[0033] In actual use, the cooling tube 5 is made of soft high and low temperature resistant material, and the cable is composed of an outer sheath 1, a signal cable core 3 and a current-carrying cable core 4. When the cable temperature rises, the heat inside the cable will be absorbed by the cooling tube 5, and the ventilation tube 2 connects the tube cavity 8 with the outside air, and discharges the heat absorbed in the tube cavity 8 to the outside of the cable through the ventilation tube 2, thereby realizing automatic cooling of the cable. Moreover, since the higher the temperature, the lower the air pressure, when the cable surface rises locally, the air elsewhere in the tube cavity 8 will flow to the place where the temperature rises, and the guide block 10 will better guide the air flow in the tube cavity 8. On the one hand, the air flow in the tube cavity 8 will neutralize the air temperature, and on the other hand, it will accelerate the air exchange between the tube cavity 8 and the outside of the cable, so as to more effectively cool down the local temperature rise of the cable and increase the service life of the cable.
