Micro heat exchangers, Micro-scale heat exchangers, or
microstructured heat exchangers are
heat exchangers in which (at least one)
fluid flows in lateral confinements with typical dimensions below 1 mm. The most typical such confinement are
microchannels, which are channels with a
hydraulic diameter below 1 mm. Microchannel heat exchangers can be made from metal, ceramic, and even low-cost plastic. Microchannel heat exchangers can be used for many applications including:
