Overclockers attempting (often in vain) to use them for sub-ambient-temperature cooling for computer components have known this for a long time.
aren’t you still limited by ambient air temp because the hot side of the Peltier needs to be cooled by air anyway?
I have a Peltier based car cooler, and that’s basically the only use case for these things that makes sense:
I don’t really even see the point of that to be honest. if we’re talking short periods anyway, a nicely insulated cooler with ice packs (cooled by a heat-pump freezers) is way better imo.
Planing a cooler presentation when I get my Redneck Business channel going. I’m stunned by how ignorant people are on the subject. My $100 Lifetime cooler keeps cold exactly as long as a $500 RTIC or Yeti. And those are only for if you need multiple days of cool. I have a dozen coolers for various needs, and most are Igloos I got from the thrift.
