Experimental Investigation on Heat Transfer Characteristics of Thin Film Evaporation

Article Preview

Abstract:

Thin film evaporation is a kind of high efficiency heat transfer. A thin film evaporator with rectangular micro groove has been designed, constructed and tested. The heat flux, superheat and thermal resistance of the thin film evaporator were investigated under different evaporating temperatures. Compared with the regular evaporator at the same condition, the thin film evaporator with rectangular micro groove has a better heat transfer performance and good temperature uniformity. The experimental investigation presented in this paper can be used as a reference to promote the engineering application and development of the thin film evaporator.
