摘要	The present invention offers an improvement over prior art cooling systems by accounting for rapid changes in thermal load. The circulation rate of refrigerant in a cooling cycle is set so that the two phase mixture exiting the cold plate evaporator device (18) stays within a saturation dome of all mixtures between a saturated liquid and a saturated vapor. Furthermore, the two phase mixture exiting the cold plate evaporator device (18) is allowed to move within the saturation dome so that the exit quality of the two phase mixture leaving the cold plate evaporator device (18) changes with the heat load being removed. In this way, rapid changes-in heat load are removed from the component (20) or components in contact with the cold plate evaporator device (18) without having to change the circulation rate of refrigerant in the cycle. Only the exit quality of the vapor leaving the cold plate/evaporator (18) changes.
其他摘要	本发明通过考虑热负荷的快速变化提供了对现有技术的冷却系统的改进。冷却循环中的制冷剂的循环速率被设置成使得离开冷板蒸发器装置（18）的两相混合物保持在饱和液体和饱和蒸汽之间的所有混合物的饱和穹顶内。此外，允许离开冷板蒸发器装置（18）的两相混合物在饱和拱顶内移动，使得离开冷板蒸发器装置（18）的两相混合物的离开质量随着去除的热负荷而改变。以这种方式，从部件（20）或与冷板蒸发器装置（18）接触的部件中去除热负荷的快速变化，而不必改变循环中的制冷剂的循环速率。只有离开冷板/蒸发器（18）的蒸汽的离开质量改变。
主权项	A pumped liquid multiphase cooling cycle method for controlling the cooling of variable heat loads in heat generating devices, comprising the steps of: providing at least one component generating heat and required to be cooled; providing at least one cold plate evaporator device in thermal contact with the at least one component; providing a liquid refrigerant pump having at least an inlet; providing a vaporizable refrigerant circulated by the liquid refrigerant pump to the at least one cold plate evaporator device, whereby the refrigerant is at least partially evaporated by the heat generated by the at least one component, creating a vapor; providing a condenser for condensing the partially evaporated refrigerant vapor, creating a single liquid phase; providing a first liquid conduit for receiving the vaporizable refrigerant from the liquid refrigerant pump, said first liquid conduit connected to the at least one cold plate evaporator device; providing a second conduit from the at least one cold plate evaporator device, said second conduit connected to the condenser; providing a liquid return line from the condenser to the inlet of the refrigerant pump; and allowing a two phase liquid vapor mixture exiting the cold plate evaporator device to adjust within a saturation dome defined by the pumped liquid multiphase cooling cycle whereby exit quality of the two phase liquid vapor mixture leaving the cold plate evaporator device changes with the variable heat loads being removed by the cold plate evaporator device.
