>consider isolating them with thermal material
This only slows down the transfer of heat, both in and out. I'd be surprised if anything useful would come of this as eventually the cap is going to achieve equilibrium with the environment, or if you wrap it up in a small coat, it will take longer to transfer heat out of the cap than normal and run hot.
- city41 8y agoI thought OP meant use thermal material while doing the repair, such as when using heat guns or soldering irons.
- robocat 8y agoThink a linear wall of isolation, so the capacitor can still dissipate heat to the air. A jacket around the capacitor would be a bad idea, especially since capacitors can generate heat internally, and heat is what we don't want!
- magicalhippo 8y agoTheir lifetime is also non-linear with respect to ambient temperature. A 10 C reduction[1] in ambient temperature roughly doubles the lifetime. So shielding the capacitor from heat can be very beneficial, even if it's just a few degrees. [1]: www.rubycon.co.jp/en/products/alumi/pdf/life.pdf
- syrrim 8y ago>eventually the cap is going to achieve equilibrium with the environment the environment is probably around 25 degrees. It's sitting between the environment and some heat producing element, so it will reach steady state somewhere between 25 degrees and the temp of that element. Making it as far away (thermally) as you can from that element should lower it's steady state temperature.
