Abstract
A flow control cartridge is used with a cold plate to form a cold plate assembly within which a refrigerant circulates for cooling at least one heat generating device. The cartridge includes a thermal expansion valve and a sensing portion that with a bellows-type actuator within the cartridge. The bellows-type actuator is located directly in a stream of the refrigerant exiting the cold plate. The thermal expansion valve is comprised of a main body having an inlet orifice arranged to receive refrigerant that has been subcooled from a condenser of a vapor compression system or a recuperative heat exchanger, and a needle arranged in an expanded section of the main body in association with discharge ports in the expanded section for discharging the refrigerant in a two-phase state into the cold plate.
