Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coolant temperature is maintained at a static level based on worst-case power dissipation, then the junction temperature stays under the predesignated maximum, but energy consumption increases excessively
Solution Approach 1:
The patent applies dynamics by transitioning from a static coolant temperature regulation approach to a dynamic one that adapts to varying power consumption conditions. The system continuously monitors power profile inputs and adjusts the coolant temperature regulation point accordingly, ensuring the junction temperature remains under the predesignated maximum while optimizing energy consumption based on actual thermal demands.
Solution Approach 2:
The patent implements parameter changes by modifying the coolant temperature regulation point and coolant flow rate based on estimated peak junction temperature and power consumption levels. These parameter adjustments allow the system to maintain reliable junction temperature control while reducing unnecessary cooling headroom and energy waste during lower power consumption periods.
2Reliability
If coolant temperature regulation point is lowered for maximum power conditions, then junction temperature is controlled under worst-case scenarios, but energy waste increases during lower power consumption
Solution Approach 1:
The patent applies partial action by providing only the necessary cooling headroom required for the current power consumption level rather than maintaining excessive cooling capacity for worst-case scenarios. The system estimates peak junction temperature and adjusts the coolant temperature regulation point to provide adequate thermal protection while eliminating unnecessary cooling energy waste during lower power consumption periods.
3Reliability
If coolant flow rate is maintained at high level for maximum thermal ramp-up, then junction temperature is controlled effectively, but energy consumption increases unnecessarily
Solution Approach 1:
The patent applies dynamics by adjusting the coolant flow rate dynamically based on actual thermal demands and power profile inputs. The system monitors power consumption levels and modifies the coolant flow rate accordingly, maintaining effective thermal ramp-up control during high power conditions while reducing pump energy consumption during lower power consumption periods.

AI summary
Methods for thermal cooling implemented by a processor of a thermal cooling system may include receiving a power profile input associated with a power consuming unit cooled by a coolant within the thermal cooling system, estimating a peak Tj of the power consuming unit during an upcoming interval based on the power profile input, a coolant temperature regulation point, and a coolant flow rate, and changing at least one of the coolant temperature regulation point or the coolant flow rate in response to the estimated peak Tj varying from a predesignated Tj limit by a predetermined threshold.
