Abstract:
1. A computer-implemented method for optimizing heat transfer in a 3-D chip-stack, the method comprising the steps of: receiving a heat-removal effectiveness parameter for a plurality of channel-region areas in the chip-stack; identifying at least two channel-region areas of the plurality of channel region areas with different heat-removal effectiveness parameters; receiving at least one of a flow value and temperature value for at least two of the plurality of channel-region areas; comparing the received values for different channel-region areas; and adjusting a flow rate of a liquid flowing to at least one of the two channel-region areas based on the heat-removal effectiveness parameter of the channel-region area receiving the adjustment and the results of the comparison step; wherein at least one step is carried out using a computer device; wherein the identified at least two channel-region areas and the subsequent value-received at the at least two channel-region areas are the same; wherein the results of the identifying step are used for one of (i) determining the order of the adjustment or (ii) establishing a range for at least one of the values wherein the liquid is one of (i) a coolant liquid, (ii) a heating liquid, or (iii) a combination of coolant liquid and heating liquid; and wherein the adjusting occurs in a manner that is proportionate to the heat-removal effectiveness parameter of the channel-region area receiving the adjustment and the results of the comparison step.
