US Patent 7643910 Spray chamber valve control system

A spray chamber valve control system for ensuring that coolant is sufficiently available at the intakes of pumps in a spray cooled environment regardless of the attitude, acceleration or deceleration of a spray chassis. The spray chamber valve control system includes a spray chassis with an interior portion for spray cooling electronic devices, a plurality of valves positioned within the inner corners of the spray chassis, and a control unit in communication with the valves for controlling the operation thereof. The control unit ensures that at least one valve is open at all times. The control unit also provides a recovery routine for when only one valve is open during a valve state change.
