You really mean passive Thermal. Remember, there is near Infra-red 
and far Infra-red. The thermal stuff is far and has a much longer 
wavelength than the near infra red does.

You still have to vent the heat somewhere. I'd think a spray of water 
that was just a bit cooler than ambient would help a good bit.
