Solution Approach 1:

The water-cooling plate is divided into multiple independent heat-conducting tubes (first heat-conducting square tube, second heat-conducting square tube, etc.) that are connected together. Each tube can be manufactured separately using extrusion processes, allowing for larger and more flexible heat exchange channels while reducing manufacturing complexity and cost compared to monolithic CNC machining.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the manufacturing method from CNC machining to extrusion processes. This parameter change enables the production of heat-conducting tubes with larger cross-sectional areas and more complex internal flow channels, significantly increasing the heat exchange channel volume while reducing manufacturing costs through more efficient production processes.

Solution Approach 1:

By segmenting the water-cooling plate into multiple connected heat-conducting tubes, the patent creates a modular structure that allows for expanded heat exchange capacity. The tubes can be arranged in series or parallel configurations, increasing the total heat exchange channel volume and improving heat dissipation efficiency without compromising structural integrity.

Inventive Principle:

Solution Approach 2:

The patent employs nested connections where heat-conducting tubes are joined together through interconnected structures (such as communication ports and coupling mechanisms). This nesting approach allows multiple tubes to work together as an integrated system, maximizing heat exchange surface area and volume while maintaining structural coherence.
