Abstract: A modular system (e.g., for establishing circulation availability of liquid coolant for datacenter components) can include a set of cabinets couplable together to form a coolant loop having a supply side and a return side. The cabinets can include at least one pressure imparting cabinet, at least one coolant distributing cabinet, and/or at least one heat exchanging cabinet. A pump included in a pressure imparting cabinet may circulate coolant through the coolant loop. A manifold included in a coolant distributing cabinet may distribute coolant along the supply side of the coolant loop toward heat-generating components and direct coolant carrying heat from said components into the return side of the coolant loop. A heat exchanger included in a heat exchanging cabinet may be arranged for dissipating heat carried in the coolant loop so as to ready the coolant for use along the supply side.

Abstract: An evaporative cooling module may include a cooling media formed from a vapor permeable membrane in which is formed a plurality of pores at a first side and a second side of the vapor permeable membrane. Individual pores of the plurality of pores may be sized to prevent liquid water from passing there through, and enable water vapor to pass there through. The cooling media may be configured to hold liquid water while an air stream is passed through the cooling media. The evaporative cooling module may also include a module inlet to direct liquid water into the cooling media, a module outlet to direct liquid water out of the cooling media, and a frame configured to support the evaporative cooling module.
