Hot-spot self-cooling effects on two-phase flow of R245fa in 85μm-wide multi-microchannels

Thermal management of servers is becoming more and more challenging and current air-cooled systems are reaching their limits regarding cooling capacity. Power consumption of air-cooled data centers, now being monitored by the US Environmental Agency [1], is rising rapidly. Moving towards liquid-based cooling would decrease the power consumption and improve the cooling system's efficiency.
