Claim of US Patent No. 10,798,851

19. A method, comprising:circulating a first coolant through a first coolant loop while circulating a different second coolant through a separate second coolant loop, the first coolant loop being in thermal contact with the second coolant loop across a thermal interface;
operating one or more electronic system components in a turned on condition to produce a heat load that inputs heat to the circulating first coolant of the first coolant loop;
removing the heat from the circulating first coolant of the first coolant loop to the circulating second coolant of the second coolant loop across the thermal interface, the heat removed from the circulating first coolant being the heat input by the one or more electronic system components to the first coolant;
sensing one or more first operational parameters of the first coolant loop, the one or more first operational parameters comprising a current temperature, a current pressure and a current mass flow rate of the first coolant within the first coolant loop; and
iteratively performing a sequence of steps as follows to warm the first coolant up to a first operating temperature setpoint whenever the current temperature of the first coolant is below the first operating temperature setpoint:
a) circulating the first coolant at a maximum mass flow rate that does not result in a current first coolant pressure that exceeds a maximum working pressure of any components of the first coolant loop that are exposed to the circulating first coolant while sensing the current temperature, the current pressure and the current mass flow rate of the circulating first coolant within the first coolant loop,
b) then determining a level of additional heat to input from a heat source different from the one or more electronic system components to the circulating first coolant that is based at least in part on the sensed current mass flow rate and the sensed current temperature of the circulating first coolant,
c) then controlling the heat source to produce and input the determined level of additional heat into the circulating first coolant,
d) then iteratively repeating a) to c) until the current temperature of the first coolant is at or above the first operating temperature setpoint, and
e) then controlling the heat source to produce none of the additional heat whenever the current temperature of the first coolant is at or above the first operating temperature setpoint.
