As a part of experiment I also want the one side of this TEC(Peltier module) to be held at 50°C(where the room temperature is 25°C) and need to size a heatsink this time for the cold side. 

The hot side to be monitored includes only a taped small wire element along with a thermistor for feedback to a TEC controller, and nothing else. And in this case, the heatsink will act as a heat reservoir. But as far as I understand, this time to the cold side I have to attach a heatsink otherwise the cold side will struggle. (For temperature regulation, I can use TEC controller which can both regulate for heating and cooling application.)

Here, its about to add heat to the system rather than remove heat. In cooling, we add Qc and electrical power to find total heat. But its a bit confusing in this case.

So in this case, what should be the way of thinking in steps to come up with a reasonable heatsink for the cold side? An example using the charts of the TEC would be great.

How to size heatsink for this thermoelectric heating application
