Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.
