The regularities of capillary hydrodynamics and heat transfer during boiling, evaporation and condensation in the channels of small size, and their application to improve efficiency of microsystem devices, including a microchannel thermo control systems, microchannel evaporators and condensers, MEMS based on decomposition of a metastable liquid, etc were considered in this paper. New methods for calculating of heat transfer during boiling and evaporation in microchannels and minichannel were developed, including the critical phenomena in confined spaces. The regularities of phase explosion and explosive boiling of micro fluid volumes under high external energy density were established theoretically.
