High temperature electronic device thermal management system

A low energy usage cooling system for cooling at least one heat-generating electronic device, comprising:

• a first cooling loop, comprising
• a first coolant that is configured to remove heat created by the at least one heat-generating electronic device,
• at least one component which acts to elevate a pressure of the first coolant, and
• a first heat exchanger interface that is configured to transfer heat out of the first coolant;
• a bypass path bypassing the first heat exchanger interface and forming a fluid path between portions of the first cooling loop;
• at least one flow controlling element configured to control a flow rate of the first coolant within the portions of the first cooling loop and a flow rate of the first coolant through the bypass path;
• and
• a management system configured to
• sense the temperature of the first coolant,
• sense the current temperature at a location either inside of or outside of the location of the at least one heat-generating electronic device,
• obtain a periodic maximum temperature of an ambient environment in the vicinity of the location of the electronic device, and
• control the at least one flow controlling element, based on the sensed coolant temperature, and at least one of the current temperature and the periodic maximum temperature, to adjust the flow rate of the first coolant within the portions of the first cooling loop and the flow rate of the first coolant through the bypass path.
