Novel generator for LiBr absorption-type refrigerating machine

Presents a new spray-type generator using a heat pipe as heat source, its double spiral heat exchange tubes have good heat transfer properties. Experimentally studies the stability and high efficiency of the falling-film evaporating heat transfer with small rake angle, obtains the relationship between heat transfer coefficient and spray intensity and the dimensionless relationship between Nu number and Re number. Recommends the experimental results to be used in the generator design as a theoretical basis.
