Question
Two electronic devices are embedded in a substrate. These devices dissipate power P1 and P2 respectively. The substrate is mounted onto a heat sink that maintains the bottom surface at the sink temperature Ts. The other surfaces are perfectly insulated.
The substrate is instrumented with a thermocouple as shown. Some independent tests of the steady-state temperature of the thermocouple are reported below: We now run another experiment with the following conditions, Ts = 15 degree C. P1 = 1 W, P2 = 2 W. What steady-state reading, Ttc, do you expect from the thermocouple under these conditions. Assume that the system can be modeled as linear?Explanation / Answer
