1. A method of thermal management of heat-generating components, the method comprising:
receiving heat from at least one heat-generating component of the heat-generating components with a primary volume of a liquid phase of a working fluid in an immersion chamber;
measuring one or more of a temperature or a pressure in the immersion chamber;
upon the one or more of the temperature or the pressure exceeding a threshold value, venting a portion of a vapor phase of the working fluid from the immersion chamber to a vapor buffer tank; and
selectively flowing, from a supplemental volume of the liquid phase of the working fluid in a liquid buffer tank, a supplemental quantity of the liquid phase of the working fluid to the primary volume of the liquid phase of the working fluid into the immersion chamber, wherein the liquid buffer tank and the vapor buffer tank are in fluid communication only through the immersion chamber.
 
12. A method of thermal management of heat-generating components, the method comprising:
receiving heat from at least one heat-generating component of the heat-generating components with a primary volume of a liquid phase of a working fluid in an immersion chamber;
measuring one or more of a temperature or a pressure in the immersion chamber;
upon the one or more of the temperature or pressure exceeding a threshold value, venting a portion of a vapor phase of the working fluid from the immersion chamber to a vapor buffer tank; and
waiting a predetermined time period after the venting, and then selectively flowing, from a supplemental volume of the liquid phase of the working fluid in a liquid buffer tank, a supplemental quantity of the liquid phase of the working fluid to the primary volume of the liquid phase of the working fluid in the immersion chamber.
