The usual observation is the Peltier system moves the heat about one millimeter, and then one needs a conventional cooler to remove the heat from that location.

- marcosdumay 4y agoYou need a conventional cooler to remove the heat from the hot side of both. The only difference is that the compression one can move the heat further away.

A conventional compressor with the same surface area of its radiator as the peltier system will perform the same (provided they are at the same temperature). This is why heatsinks on CPUs have fins: to increase the surface area where the heatsink is in contact with the (hopefully cooler) surrounding air. The windings of a radiator are very much the same idea.
- atoav 4y agoI think there is a difference in technical concepts that you are mixing up. What you are talking about is convection cooling. Both compressor based systems and peltier coolers need to transfer the removed heat to the environment. This is usually done with big surface areas and potentially fans to produce airflow. In a traditional compressor based system this huge surface area is the radiator in the back and technically it also only "moves the heat" to the surface of that radiator. But give the size of that radiator it will be effective at transfering that heat to the surrounding air. A peltier cooler with a smaller surface area needs a heat sink and or some form of active cooling (airflow, water etc).
