Abstract: A fluid circulation system for cooling a plurality of computing devices with a dielectric includes a plurality of fluid tanks, an air cooled heat exchanger, a fan and a pump. Each fluid tank includes a bottom having a plurality of apertures for receiving the dielectric fluid. Each fluid tank is configured to hold a group of computing devices over the plurality of apertures. The air-cooled heat exchanger is elevated at least fifteen feet over a support surface. The air-cooled heat exchanger is in fluid communication with the plurality of fluid tanks and is configured to receive the dielectric fluid. The fan is configured to circulate air through the air-cooled heat exchanger so as to remove thermal energy from the dielectric fluid. The pump is configured to circulate the dielectric fluid through the fluid circulation system.

Abstract: A fluid circulation system for cooling a plurality of computing devices with a dielectric fluid includes a fluid tank, a cooler, and a collector. The fluid tank includes a bottom having a plurality of apertures for receiving the dielectric fluid. The fluid tank is configured to hold the plurality of computing devices with a first computing device of the plurality of computing devices disposed over a first group of the apertures of the plurality of apertures. The cooler is configured to receive the dielectric fluid and remove thermal energy from the dielectric fluid. The collector includes a first cavity, a second cavity, a plate separating the first cavity from the second cavity, a collector inlet that opens into the first cavity and is configured to supply dielectric fluid into the collector, and a collector outlet. The fluid tank, cooler, and collector are fluidly connected in a fluid circuit.
