Whilst doing some research i thought of an idea to help release some of the heat from components in case they overheat. I know you can get aluminium heat sink but i was wondering how well does heat sink foam work?
I was thinking you could maybe put it under the vesc and other parts inside the enclosure. Does anyone know if this would work? here are some i found online…
It is copper wires coiled together to make a foam block. I was thinking of maybe having a anti-vibration foam with this on top and the the electrical components on top of that.
i would hard mount heatsinks and otherwise cushion or mount the VESC before using a bigger copper foam like this. I would guess a regular heatsink would have more surface area (in contact of FETs) and likely better heat transfer as a result. Venting any heat into the air or even enclosure to dissipate.
i was wondering why people wouldn’t use it, but i guess thats why haha, good thing i asked. I don’t tend to think too much about things, i just assume they work
Some kapton where you don’t want shorts. I can immagine this cools very well in an airstream (always while riding), maybe on top of a thin alu/copper plate.
Yup! That seems like a bad idea. But it does raise a new question: are there non-conducive foam materials that could dissipate heat? I would love to fill some of the gaps in my enclosure with something useful.
I have never mounted a heat sink that is not conductive, I would say try it out, perhaps mounted on another smaller heat sink, and have an insulater on the portions that need it. how does one mount a product like this? Epoxy with a smaller aluminuim plate? straps?
Do you have a link to the product, or a datasheet?
“can” and are good are two different things. Wood can conduct/dissipate heat, but it sucks compared to any metal.
Silver, Copper, Aluminum (gold in there too between copper and aluminum if you are rich and want bling) - from most efficient to least. Take a look at the thermal conductivity of those metals as it’s pretty interesting. Again like others mentioned why i’ve used Arctic Silver 4/5 for years on my PC’s heatsinks.
i would stick with the tried and true heatsinks vs a thermally conductive foam. i want small/light and easy. Adding some fins or the mount like @Chaka offers seems like the best solution IMO. Some thermal paste to external fins w/ airflow would be my ultimate setup (while still enclosed/sealed from elements).
Maybe wee need a 2 part system with a heatpipe, so we can dissipate heat at the bottom of the board, and rebuy the actual heatsink for cheap if it breaks / gets too scratched.
