I'm planning to build a "mobile pi", including a powerbank for power supply. These parts are put into a closed case with no air flow in it (wooden case with cloth around it). I don't think the Pi itself would take damage, but I'm affraid that the heat of the Pi might cause the powerbank to take damage/explode/leak etc.

Question: Is it likely that the heat causes big damage to the powerbank? Or should I include a fan for cooling?

  • Cooling is needed.

The power bank shoudn't get hot. The raspberry pis core is a pretty small square. As you said there is no ventilation. If possible, place the power bank on top of the older box and feed the cable into the box.

  • An external powerwank won't be possible for my project. My Idea would be to use a fann to cool the Pi, so the heat doesnt stay in the case. Or is it never a good idea to keep a powerbank in a closed case? Nov 26 '17 at 22:23
  • Test run the mobile pi. Check if the power bank is hot after a while. If it is, add two fans to the box, one to insert air, and one to remove hot air. Nov 27 '17 at 15:16
  • Wouldnt one fan be enough? But ok thanks :) Nov 27 '17 at 15:17
  • If you are using one fan, I think it would be best to draw air out of the box to remove warm air from accumulating. I don't know how noisy it would be but if it doesn't work out for you, just switch it over to push air in. Nov 27 '17 at 15:28
  • No problem. Happy to help anyone with my knowledge I have learned. Nov 27 '17 at 15:31
