I wonder if simply cooling isn't an option in those applications? I guess that'd depend on the chips power output. Otherwise you could just surround it in a really good insulator and pump residual heat out somehow (maybe can peltiers withstand such high temps using multiple stages?)
- BostonEnginerd 8y agoCooling only works if you have somewhere to put the extra energy. Peltiers are inefficient to run and generate a ton extra heat. It's best to build something that can run with as little support needed.
- darkmighty 8y agoIndeed, cooling would be quite bulky and require lots of extra energy. But for an environment like Venus cited (instead of small sensors), I think it should be a good option. The Carnot efficiency to cool from a Venutian environment (462C) down to 50C (reasonable chip temp) is a surprisingly good ~60%. In practice you might get 15% (? plus insulation leaking), that should still allow cooling a chip of less than ~1 watt of tdp without too much hassle inside a robot.
