Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a power cable with a heat dissipation function. Background Art

[0002] Power cables are cable products used to transmit and distribute high-power electric energy in the main lines of the power system. Power cables are widely used in power station lead-out lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. They have many types of products and a wide range of applications, involving industries such as electricity, construction, communications, and manufacturing, and are closely related to all sectors of the national economy. Therefore, it can be seen that the existing cables basically meet people's practical needs, but there are still the following problems.

[0003] When using power cables, current flows in the cable core. When the cable flows in the cable core, the flow may generate resistance. When resistance is generated, the temperature of the cable core may continue to rise. When the temperature rises, the temperature cannot be discharged and heat may accumulate in the cable. When the temperature rises, it may cause the cable to spontaneously combust, thus creating a safety hazard. For this reason, we propose a power cable with heat dissipation function. Utility Model Content

[0004] The utility model provides a power cable with a heat dissipation function. The heat of the cable core is conducted to the heat sink by the heat conduction ring through the heat conduction block, so that the heat sink and the air are subjected to convection heat dissipation, thereby preventing the heat generated by the cable core from accumulating in the cable and causing the cable to spontaneously combust, thereby improving the safety of the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power cable with heat dissipation function, comprising a cable core, a shielding layer wrapped around the outside of the cable core, and a filling block is filled between the shielding layer and the cable core, a flame retardant layer is wrapped around the surface of the shielding layer, and a braided layer is wrapped around the surface of the flame retardant layer, a ring is provided on the surface of the braided layer, and a heat dissipation component is embedded in the middle of the ring, a partition penetrated by the heat dissipation component is wrapped around the surface of the braided layer, and a filling layer is filled between the partition and the braided layer, and an insulating layer is provided on the surface of the partition.

[0006] Furthermore, the heat dissipation component includes a heat-conducting ring, a heat-conducting block and a heat sink. The heat-conducting blocks penetrating the braided layer and the interlayer are fixed around the heat-conducting ring, and the heat sink is fixed at the end of the heat-conducting block.

[0007] Furthermore, the surfaces of the heat sinks are all covered with support sleeves fixed to the outer side walls of the partitions.

[0008] Furthermore, a support layer is filled between the insulating layer, the partition layer and the support sleeve.

[0009] Furthermore, the fillers arranged on the support layer are all hexagonal.

[0010] The beneficial effects of the utility model are:

[0011] The power cable with heat dissipation function is provided with a heat-conducting ring, a heat-conducting block and a heat sink. The heat-conducting ring is sleeved on the surface of the braided layer, and the braided layer conducts heat to the heat-conducting ring. After the heat-conducting ring receives the heat, the heat-conducting ring conducts the heat to the heat sink through the heat-conducting block. The heat generated by the cable core is conducted to the heat sink by heat conduction, and the heat sink dissipates heat by air convection, so that the heat generated by the resistor cannot be dissipated when the cable core is in use, the cable is prevented from spontaneous combustion, and the usability of the cable core is improved.

[0016] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0017] Example:

[0018] See also Figure 1 - Figure 2A power cable with heat dissipation function comprises a cable core 1, a shielding layer 3 is wound around the outer side of the cable core 1, and a filling block 2 is filled between the shielding layer 3 and the cable core 1, a flame retardant layer 4 is wound on the surface of the shielding layer 3, and a braided layer 5 is wound on the surface of the flame retardant layer 4, a ring 6 is sleeved on the surface of the braided layer 5, and a heat dissipation component is embedded in the middle of the ring 6, the heat dissipation component comprises a heat conductive ring 7, a heat conductive block 8 and a heat sink 12, a heat conductive block 8 penetrating the braided layer 5 and a partition 10 is welded around the heat conductive ring 7, and a heat sink 12 is welded at the end of the heat conductive block 8, a partition 10 penetrated by the heat dissipation component is wound on the surface of the braided layer 5, and a filling layer 9 is filled between the partition 10 and the braided layer 5, and an insulating layer 14 is arranged on the surface of the partition 10. When the cable is in use, the current flows in the cable core 1 When the cable moves inside, when the current flows in the cable core 1, the current generates resistance in the cable core 1. When the current generates resistance, the cable core 1 generates heat. When the cable core 1 generates heat, the cable core 1 transfers the heat to the heat-conducting ring 7 embedded in the ring 6 through the filling block 2, the shielding layer 3, the flame retardant layer 4 and the braided layer 5. When the heat-conducting ring 7 receives the heat, the heat-conducting ring 7 transfers the heat to the heat sink 12 through the heat-conducting block 8. Since the surface of the heat sink 12 is in contact with the air, after the heat sink 12 receives the heat, the surface of the heat sink 12 and the air convect with each other, thereby performing convection heat dissipation, improving the convection heat dissipation between the heat sink 12 and the air, avoiding the heat generated by the cable core 1 from accumulating in the cable, causing the cable to spontaneously combust, and improving the safety of the operator.

[0019] In other embodiments, the surface of the heat sink 12 is provided with a support sleeve 11 which is hot-melt bonded to the outer wall of the partition 10. The support sleeve 11 is fixed on the outer wall of the partition 10 and is provided around the heat sink 12 to block the heat sink 12. This prevents the insulating layer 14 from blocking the surface of the heat sink 12 during long-term use, thereby preventing the heat dissipation effect of the heat sink 12 from deteriorating and improving the heat dissipation efficiency of the heat sink 12.

[0020] In other embodiments, the insulating layer 14, the partition layer 10 and the supporting sleeve 11 are all filled with a supporting layer 13, and the fillers set in the supporting layer 13 are all hexagonal. By filling the supporting layer 13 between the insulating layer 14, the partition layer 10 and the supporting sleeve 11, the supporting layer 13 increases the strength between the partition layer 10 and the insulating layer 14, thereby preventing the insulating layer 14 from being recessed during normal use. In addition, the supporting layer 13 is set as a hexagonal filler, so that the hexagon has a good supporting structure, which increases the stability of the supporting layer 13 supporting the insulating layer 14.

[0021] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
