Type of article: Article

Summary

Pool boiling and internal heat transfer coefficients are experimentally analyzed of a kind of enhanced tube with the widely used R22 as refrigerant. The heating medium is water in tube. Maintain heat flux and saturation pressure constant, while vary inlet water temperature and velocity, then a series of data are obtained, inner and outer heat transfer coefficient correlations can simultaneously be figured out with Wilson Plot method. The heat transfer coefficient of the enhanced tube is larger than that of the low-fin tube. Within experimental conditions, the inner thermal resistance dominates.
