AI Technical Summary

Technical Problem

In existing liquid-cooled cable designs, the coolant does not directly contact the conductor, resulting in low heat transfer efficiency and easy deformation of the outer material, affecting the flow of coolant and the stability of the cable.

Method used

It adopts a flame-retardant outer tube, a cross-shaped outer shaft tube, a convex inner shaft tube, and a cooling flow structure, including components such as a heat-conducting sleeve, a return sleeve, arc blades, and heat dissipation metal plates. It is designed with a spiral flow path to enhance the contact and flow between the coolant and the conductor, and accelerates heat dissipation through the heat-conducting sleeve.

Benefits of technology

It achieves efficient and uniform cooling, reduces heat loss, improves cooling efficiency, and ensures the stability and safety of the cable.
