AI Technical Summary
Technical Problem
Existing graphics card coolers have a small contact area between the heatsink and the water cooling pipes, resulting in poor heat conduction, and the unibody design increases manufacturing costs.
Method used
The heat sink and water cooling block are set up separately. The bottom side of the heat sink is bent into a right angle and rests against the water cooling block to increase the heat conduction area. Heat is transferred through water cooling pipes and cooling fans.
Benefits of technology
It achieves rapid heat transfer, reduces manufacturing costs, and improves thermal conductivity and heat dissipation uniformity.
