Hey everyone! I'm curious if a Peltier module can actually cool a shoebox to below 60°C when the outside air temperature is also at 60°C. I've got passive heat sinks on both sides—one inside the box for cooling, and the other outside for heating, plus a fan to move air over the heated side. Would this setup work?

Honestly, I don't think a Peltier module is going to get the job done here. These things really need proper airflow to work efficiently, and if they can't get rid of the heat quickly enough, both sides will just end up heating up. Plus, they're not exactly efficient either. What kind of project are you working on? Maybe we can find a better solution!
You might be able to get it below 60°C, but I wouldn't expect the temperature to be even throughout the box without some airflow. Have you thought about adding a fan inside? That could help distribute the cold more effectively. If you're looking for real efficiency, a proper refrigerant system would work better but it might be too big for just a shoebox.
Thanks for the suggestion! I'm limited on space though, and I really only have the shoebox size to work with.
