Description

Technical Field

[0001] The utility model relates to the technical field of new energy, in particular to a liquid-cooled cable. Background Art

[0002] With the development of the new energy vehicle industry, the charging problem has been plaguing everyone. At present, many related enterprises have developed various charging interfaces and charging devices, but still cannot meet the requirements of new energy vehicle owners for charging speed. Super fast charging has thus emerged.

[0003] Existing liquid-cooled charging seat products on the market are all composed of a separate cable and a separate liquid-cooled tube. That is to say, cooling can only be achieved in the charging seat, and then the cooling tube is led out separately. In this way, the cable part cannot be effectively cooled, and it is even more impossible to realize a complete liquid-cooling cycle after the coolant passes through the battery pack.

[0004] The existing cables for DC+ and DC- of the charging seat also directly use the previous cables. These cables are relatively thick and not easy to bend, which is not friendly to the wiring of the cables on the whole vehicle. Summary of the Utility Model

[0005] The utility model provides a liquid-cooled cable.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A liquid-cooled cable includes a cable outer skin. A conductor is arranged inside the cable outer skin. The conductor is of a tubular structure and includes a tube body. A plurality of grooves are arranged on the tube body, and the thickness A1 of the tube body is not less than the thickness A2 of the grooves.

[0008] Further, a cooling tube is arranged inside the tube body.

[0009] Further, a plurality of annular grooves are arranged on the tube body.

[0010] Further, the grooves are axially distributed on the tube body.

[0011] Further, spiral grooves are arranged on the tube body.

[0012] Further, the thickness A1 of the tube body is greater than the thickness A2 of the grooves.

[0013] Advantages: By arranging grooves on the conductor, the utility model makes it have a wavy structure, which enables it to have reliable power conduction and the characteristic of being easy to bend while having the wavy structure. The coolant tube is integrated into the cable, so that even if the cable is bent, it will not affect the normal circulation of the coolant. Description of the Drawings
