Does someone of you tried to use a peltier cell to cool the “cold end” of the hot end?
There have been people who water cool the cold end, and I wouldn’t be surprised if someone eventually took a CPU cooler, strapped it into their water-line and sandwiched a peltier between it.
The problem with using peltiers for cooling is that they generate more heat on the hot side than they suck up on the cold side, and that heat has to go somewhere.
Yes, I agree with you @Whosa_whatsis , but as I have to heat up the hot bed anyway ( or the entire model ) I was thinking if it is feasible to redirect all that heat to the model/hotbed…
A peltier doesn’t seem to be a good enough insulator to create enough temperature differential to be terribly useful on both sides. The only way to keep the “cold” side from continuing to heat up is to dump heat out of the hot side in as fast and un-controlled a way as possible. Not saying there’s not a way to make use of it, it’s just that peltiers seem to always sound like a much better idea than they turn out to be in practice
yeah, I recently tried it to control the cold end, and it was a huge mistake. The amount of heat from the hot side of the peltier turned out to be enormous. Far more than I thought, so it resulted in a steadily increasing temperature of the cold side. I’m now experimening with a heatpipe I took from a aging computer…Works much better.
@Whosa_whatsis one of the only uses I could see for a peltier is a bed cooler for printing chocolate or something, this would require a nice bit of syncing and cooling on the hot side. But it could be useful.
