Could be useful in space where those are the default conditions

Space is a fantastic insulator. Space suits for astronauts have to be cooled, not heated.

I think it’s more appropriate to say conduction and convection doesn’t work well. When you have a suit, it’s meant to block radiation and that’s the mode of heat transfer in space. If space was a fantastic insulator, the suit itself would eventually overheat since you have to remove the heat somehow (they boil off water in vacuum similar to sweat).
