Electronic circuit boards are arranged as respective parallel pairs defining a narrow gap there between. One or more such pairs of boards are supported within a hermitically sealable housing and cooled by way of spraying an atomized liquid coolant from a plurality of nozzles into each narrow gap. Transfer of heat from the circuit boards results in vaporization of at least some of the atomized liquid within the narrow gap. The housing further serves to guide a circulation of vapors out of each narrow gap, back toward the nozzles, and back into each narrow gap. A heat exchanger exhausts heat from the housing and overall system, wherein vapor is condensed back to liquid phase during contact and heat transfer therewith. Condensed liquid is collected and re-pressurized for delivery back to the nozzles such that a sustained cooling operation is performed.

Narrow gap spray cooling in a globally cooled enclosure

An insulated spray cooling system for extreme environments for providing a desired enclosed environment for electronic devices regardless of external environmental conditions. The insulated spray cooling system for extreme environments includes an insulated enclosure that isolates the electronic devices being thermally managed from the external environment and a thermal management unit within the enclosure for thermally managing electronic devices.

Insulated spray cooling system for extreme environments

An azeotrope spray cooling system for utilizing an azeotrope coolant for improving the performance of a spray cooling system. An azeotrope coolant is utilized within a two-phase thermal management system for thermally managing one or more heat producing devices. The characteristics of the azeotrope coolant may be adjusted for various types of thermal management applications by altering the components of the azeotrope coolant.

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.

Passive fluid recovery system

A server farm liquid thermal management system that is efficiently maintained. The server farm liquid thermal management system generally includes a coolant reservoir fluidly connected to a plurality of thermal management units. A supply line from the coolant reservoir is fluidly connected to the thermal management units with a plurality of fill valves positioned within the supply line to selectively control flow to the thermal management units. A return line is fluidly connected to the thermal management units with a plurality of drain valves positioned within the return line to selectively control the draining of the thermal management units. A control unit monitors the coolant levels within each of the thermal management units thereby supplying or removing liquid coolant within each to maintain a desired coolant level.

Server farm liquid thermal management system

An actuated atomizer is adapted for spray cooling or other applications wherein a well-developed, homogeneous and generally conical spray mist is required. The actuated atomizer includes an outer shell formed by an inner ring; an outer ring; an actuator insert and a cap. A nozzle framework is positioned within the actuator insert. A base of the nozzle framework defines swirl inlets, a swirl chamber and a swirl chamber. A nozzle insert defines a center inlet and feed ports. A spool is positioned within the coil housing, and carries the coil windings having a number of turns calculated to result in a magnetic field of sufficient strength to overcome the bias of the spring. A plunger moves in response to the magnetic field of the windings. A stop prevents the pintle from being withdrawn excessively. A pintle, positioned by the plunger, moves between first and second positions. In the first position, the head of the pintle blocks the discharge passage of the nozzle framework, thereby preventing the atomizer from discharging fluid. In the second position, the pintle is withdrawn from the swirl chamber, allowing the atomizer to release atomized fluid. A spring biases the pintle to block the discharge passage. The strength of the spring is overcome, however, by the magnetic field created by the windings positioned on the spool, which withdraws the plunger into the spool and further compresses the spring.
