ABSTRACT:
A method and apparatus for transferring heat for the purpose of purifying raw feed liquid, vaporizing heat transfer fluids or containing and regulating biological/chemical reactions. The raw feed liquid is directed into an evaporator module submerged in a solar pond or other body of heated liquid. The evaporator module includes a rotating housing through which a plurality of spaced apart substantially horizontal open ended heat transfer tubes extend. A heating liquid is directed through the heat transfer tubes. The raw feedwater is distributed within the evaporator module so as to cause the feedwater to descend into heat transferring contact with the heat transfer tubes and thereby vaporize a portion of the feedwater. The vapor formed in the evaporator module is withdrawn from the evaporator module and directed to a suitable condenser. A preferred embodiment of the evaporator module is disclosed which includes cavitation fins for urging the heated liquid through the evaporator module.
