Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically, to a mobile liquid-cooled cable. Background Art

[0002] Mobile flexible cables are mainly cables with a rubber insulation (or similar material) sheath and a conductor structure of the 5th or 6th type. The bending radius of this kind of cable is 5 - 6 times, and the sheath is wear-resistant. Therefore, it is suitable for mobile occasions and is called a mobile flexible cable. A flexible cable refers to a cable made by bundling multiple strands of fine copper wires. Its cable usually has a dozen to dozens of cores and a smaller bending radius; a non-flexible cable is a cable made by bundling a single or a few thicker cables, with a larger bending radius. However, the common cables have poor flexibility and are easily damaged when pulled and bent, thereby reducing the service life of the equipment.

[0003] In the existing patent, a mobile flexible cable, with the patent authorization number CN213781629U, is made by stranding thinner copper wires, which greatly increases the flexibility of the cable. By setting a metal wire braided mesh, the main cable core body and the auxiliary cable core body can be tightly wrapped, thus ensuring the use of the cable. Since mica tape has excellent high-temperature resistance and combustion resistance, the flame retardant performance of this product is increased, and mica tape has good softness, thus ensuring the flexibility of the cable. Since the cable protection sleeve has excellent properties such as good insulation performance, high chemical stability, non-rusting, non-aging, and good wear resistance, the insulation and wear resistance of the cable of the utility model are greatly increased.

[0004] However, during the operation of the cable with the patent authorization number CN213781629U, a large amount of heat is generated in its core wires under the influence of resistance, and these heats cannot be dissipated in time, resulting in heat accumulation, which easily causes the cable to overheat and catch fire. Therefore, we propose a mobile liquid-cooled cable to solve the above existing problems. Summary of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a mobile liquid-cooled cable. It can be set that both the inflow channel and the return channel are in a continuous S-shaped structure, and the cross-sections of the inflow channel and the return channel are both in a flat structure, which extends the flow path of the refrigerant and increases the heat exchange area, taking away the heat generated by the cable core, the ground wire core, the signal wire core, and the conductor wire core. After the refrigerant flows out through the liquid outlet, it exchanges heat and then flows back through the liquid inlet and circulates in this way, effectively avoiding the cable from overheating and catching fire.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment:

[0034] Please refer to Figure 1-6, The mobile liquid-cooled cable includes a cable core 1, a ground wire core 2, a signal wire core 3, and a conductor wire core 4. A protective sleeve 5 is coated on the outer sides of the cable core 1, the ground wire core 2, the signal wire core 3, and the conductor wire core 4;

[0035] On the inner sides of the protective sleeve 5, an inflow channel 6 and a return channel 8 are respectively arranged. Both the inflow channel 6 and the return channel 8 are arranged in a continuous S-shaped structure, and the end of the inflow channel 6 is conductively connected to the end of the return channel 8;

[0036] On the outer sides of the protective sleeve 5, a liquid inlet 7 and a liquid outlet 9 are respectively arranged. The liquid inlet 7 is conductively connected to the end of the inflow channel 6, and the end of the liquid outlet 9 is conductively connected to the liquid outlet 9;

[0037] The inner sides of the inflow channel 6 and the return channel 8 are both filled with liquid refrigerant;

[0038] It should be noted that when the mobile liquid-cooled cable is in use, first, the liquid inlet 7 and the liquid outlet 9 are connected by a pipeline and connected to a heat exchanger and a circulation pump. The liquid refrigerant enters the inner side of the inflow channel 6 through the liquid inlet 7, and then flows into the return channel 8. Since both the inflow channel 6 and the return channel 8 are arranged in a continuous S-shaped structure, and the cross-sections of both the inflow channel 6 and the return channel 8 are in a flat structure, the flow path of the refrigerant is extended, and the heat exchange area is increased, taking away the heat generated by the cable core 1, the ground wire core 2, the signal wire core 3, and the conductor wire core 4. After the refrigerant flows out through the liquid outlet 9, it is heat-exchanged and then flows into through the liquid inlet 7 again and circulates in this way, effectively avoiding the cable from overheating and catching fire.

[0039] As Figure 1 , Figure 3 shown, there are two cable cores 1 symmetrically arranged, the ground wire core 2 is located between the cable cores 1, and the signal wire core 3 and the conductor wire core 4 are respectively located on both sides of the cable core 1;

[0040] The cable core 1, the ground wire core 2, the signal wire core 3, and the conductor wire core 4 are arranged in a straight line.

[0041] The radial cross-sections of the cable core 1, the ground wire core 2, the signal wire core 3, and the conductor wire core 4 are all in a circular structure.

[0042] The protective sleeve 5 is arranged in a flat long strip structure.

[0043] The ratio of the length to the width of the cross-section of the protective sleeve 5 is greater than 2;

[0044] It should be noted that since the cable is arranged in a flat strip structure as a whole, effective space can be saved after the cable is wound, thus facilitating the overall transfer of the cable.

[0045] The liquid refrigerant is a fluorinated liquid coolant.

[0046] As Figure 1As shown, steel stranded wires 10 are provided on one side of the signal wire core 3 and the conductor wire core 4 away from the cable core 1, and the steel stranded wires 10 are covered inside the protective sleeve 5;

[0047] It should be noted that the two symmetrically arranged steel stranded wires 10 are horizontally symmetrically distributed inside the protective sleeve 5. By utilizing the characteristics of the steel stranded wires 10, the overall tensile effect of the cable can be effectively improved, thereby enhancing the structural strength of the cable.

[0048] During use: First, connect the liquid inlet 7 and the liquid outlet 9 through a pipeline and connect them to a heat exchanger and a circulation pump. The liquid refrigerant enters the inner side of the inlet flow channel 6 through the liquid inlet 7, and then flows into the return flow channel 8. Since both the inlet flow channel 6 and the return flow channel 8 are arranged in a continuous S-shaped structure, and the cross-sections of the inlet flow channel 6 and the return flow channel 8 are both flat-shaped structures, the flow path of the refrigerant is extended and the heat exchange area is increased, taking away the heat generated by the cable core 1, the ground wire core 2, the signal wire core 3, and the conductor wire core 4. After the refrigerant flows out through the liquid outlet 9, it undergoes heat exchange and then flows into the liquid inlet 7 again and circulates in this way.

[0049] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
