There is described a spray chamber for cooling a computer processor on a circuit board. The spray chamber comprises: a wall assembly for sealable mounting on an exposed cooling surface of the computer processor defining an enclosure having a top opening and a bottom opening which opens on the top surface of the computer processor; and a lid for covering the top opening of the wall assembly in a sealable manner, the lid having a nozzle which sprays coolant that impinges on the exposed cooling surface of the computer processor.

CPU cooling system with direct spray cooling

A device for cooling a processor which comprises a chamber which is bottomless and having a perimeter sealably mounted directly on a surface of a processor; a microgap plate, separate from the chamber, which is installed at a bottom of the chamber and forms a microgap with the surface of a processor; and a lid, separate from the chamber, which is installed onto the chamber to close a top of the chamber, the lid comprising downward projections to urge the microgap plate to the bottom of the chamber during installation. Walls forming the downward projections of the lid form a lining conforming to an inner surface of walls of the chamber, wherein the lid and the downward projections thereof together form a bottomless enclosure that defines an inlet plenum volume for receiving the coolant. The microgap comprises a central inlet through the microgap plate for coolant flow into the microgap.
