AI Technical Summary

Technical Problem

In existing graphics card water cooling systems, the power supply wires for the water radiator fans need to be routed from the motherboard, resulting in messy cables that affect the neatness and aesthetics of the case and pose safety hazards.

Method used

Design a connection structure between a graphics card PCB and a water exhaust fan. The structure uses a combination of inner and outer tubes for cable routing and a cable protection component. The wires are placed inside the inner tube through the cable routing channel on the outside of the inner tube. Wireless cabling is achieved by combining a heat insulation pad and a retaining ring structure. The cable protection component is used to fix and protect the wires.

Benefits of technology

This technology enables wireless connection between the graphics card PCB and the water cooling fan, improving the overall neatness and aesthetics of the structure, while also enhancing the durability and safety of the wires.
