Lightweight Heatsinks

Tue Nov 15, 2016 4:38 pm

I am working on designing lightweight heatsinks for the PI - has anyone any uses or can they suggest environments where they may be useful?

would seem a job for a 3d printer using metal, to take the heat out of the case, can fill it with channels to so that something else other than air can flow, my son and I are looking at 3D printers at the moment and constructing a friendly case for the Pi 3 CPU could be a worthwhile project as all other cases seem to be constructed more for image than anything else. well the Pi 3 does run a lot hotter than those before it so why should its exterior look the same, isn't that thinking inside the box?

The usual aluminium heatsinks for the Pi3 which are a 14-15mm cube, weigh so little that they don't register on my electronic scales - I guess around 1 gram or less. Not sure how much lighter you could go.

I prefer heavier heatsinks to provide some degree of thermal inertia. My C2 has a 70 gram heatsink.

these are great, 100th of a gram, max weight is 200 gram.

You can get ceramic heatsinks for the Pi, they are supposed to cool better than aluminum or copper.
