With diminishing levels in silicon design efficiency (aka the slowdown in Dennard Scaling), cooling has taken center stage in server innovation to enable both designs that can dissipate higher levels of power to improve server performance and to improve cooling efficiency to reduce the Total Cost of Ownership, a metric that big datacenter owners strive to optimize. EcoCloud’s John Thome is a pioneer in two-phase liquid cooling in servers, where cooling liquid is circulated in two phases to improve heat removal efficiency while requiring a lower flow rate (for lower operation cost) and enabling better temperature uniformity across the chip. In collaboration with Jackson Marcinichen, they have recently invented two-phase cooling at the chip level for maximum efficiency. Their technology is showcased on the cover of Electronics Cooling, a high-profile magazine dedicated to thermal management in electronics industry.
