Abstract

A counterflow evaporative heat exchanger employs parallel vertical uninterrupted coil containing sections having the sides thereof arranged to increase the area of liquid contact within the tubes, the smooth flow of a liquid film on the outside of the tubes, and to increase the impingement of gases against the outsides of the tubes thereby providing smooth liquid flow the full vertical length of each section and permitting the use of maximum air velocity with turbulence but with a minimum of liquid entrainment in the gas stream, thereby enhancing cooling of the internal liquid and reducing the space required for the coil assembly.
