Choosing Cooling Solution For Enclosed Raspberry PI and LIPO battery

Wed Oct 17, 2018 3:16 pm

I have a raspbery PI B+ connected to a PiJuice HAT (https://www.sparkfun.com/products/14803) that I want to build a case for. Does anyone have experience using both that can attest to the amount of heat that would be created? My current plan is to just monitor the temps at a few points around the case and to set up some PWM fans, in addition to buying a heat-sink for the PI.

Also, in all my google searches for PWM fan raspberry PI tutorials, i've never heard it suggested to just buy a PWM fan. Why would I buy a custom-PCB with FETs to power fans when I can just buy a 4 pin PWM fan like the following?:

Is that a Raspberry Pi B+ https://www.raspberrypi.org/products/ra ... el-b-plus/
or a Raspberry Pi 3B+ https://www.raspberrypi.org/products/ra ... el-b-plus/ ?

The CPU temperature of my Raspberry Pi 3B+ with PiJuice attached, not in a case, was steady around 50 C when it was basically idle. I didn't manage to try it in a case and under stress, but I felt it would probably need a fan.

If your into DIY business, you could possibly either 3D print a case after taking measurements, or make a case out of wood. Create a hole at the side of the case and insert a small GPIO fan.

B+.

My main concern now is implementing a fail-safe to ensure the LIPO battery won't explode.
