Air coolers are finned heat exchangers in which a working fluid heats up with heat absorption from the environment to be cooled, without changing the aggregate state. The units serve as components of a system, e.g. for conditioning the room air or cooling goods.

Evaporators are finned heat exchangers serving as components of a refrigeration system, in which liquid refrigerant evaporates with heat absorption from the environment to be cooled. The units are used e.g. in deep-freeze applications in food storage.
