| Abstract Scope |
As cloud computing's role expands, data center energy consumption, especially for cooling, becomes a significant challenge. This project aims to develop an energy-efficient two-phase cooling system for data centers, targeting less than 5% of total energy use for cooling and eliminating water consumption. We propose a novel two-phase wick structure with thermal resistance below 0.01 K/W, directly printed on chips without thermal interface materials using an innovative inter-material. Topology optimization of the heatsink design enhances cooling for high-power chips, crucial for AI applications. We've optimized wick porosity and microstructure through process development studies, validated by using SEM, optical microscopy, and CT-scan. An optimized manifold design using vat polymerization ensures uniform flow distribution. Test artifacts with varied dimensions and material compatibility tests were fabricated to finalize design parameters and identify optimal coolant materials. |
