Effects of Microstructure Types on the Evaporation Efficiency of Electrically Heated Micro Evaporator

Abstract

In this work, a laminated microstructure-plate electrically heated micro evaporator was proposed. The effects of microstructure types on the evaporation efficiency of electrically heated micro evaporator under different input voltage values and flow rates of water were investigated. It was indicated that the triangular microstructure plate presented the best evaporation efficiency regardless of the change of input voltage and feed flow rate. The nonuniform-distributed microchannel plate presented better evaporation performance than that of uniform-distributed microchannel plate, while the triangular microstructure plate presented higher evaporative performance than that of rectangular microstructure plate.
