The example I gave > has a heat source at a lower temperature than the heat sink. Most of the energy is coming in from the outside. This would create a barrior to that heat coming inside. You put up a layer of _good_ insulation just inside of that heatsink. You put up a second heatsink on the inside of the insulation.
