US Patent 7717162 Passive fluid recovery system

A fluid recovery system is adapted for use with a cooling system, such as for use in electronic applications. In one example, an enclosure is configured to contain fluid in both gas and liquid states, wherein the fluid is adapted for use in spray cooling electronic components. A plurality of pick-up ports is defined within the enclosure. In one implementation of the cooling system, an orifice size used in each of the pick-up ports results in withdrawal of fluid from submerged and non-submerged pick-up ports.
