Abstract
The present disclosure provides apparatus, systems, methods, and techniques for cooling using a passive internal return loop with two-phase fluids. The cooling techniques may be applied to an advanced server rack having high power density servers. The server rack may be either packaged with one or more cooling modules or employ a fully sealed immersion configuration. For example, coolant in the vapor state may be separated from coolant in the liquid state in the two-phase coolant, and the coolant in the liquid state may be recirculated to cool the server (or other sub cooling systems) by gravity (i.e., pump-free).
