ABSTRACT:
This invention is a heat exchanger device which is an improvement on U.S. Pat. No. 3,612,002, Liquid-Heating Apparatus by the same inventor. The invention is a heating or cooling apparatus for liquids which lends itself to quick disassembly and reassembly and which contains a hollow double flange inlet for the introduction of heating medium, a double helix to lead the heating medium inside of hollow concentric cylinders, and a hollow flange with two chambers for the introduction of fluid. In addition, the apparatus is modified by rounding its internal structure to allow coating of its internal surface with a corrosion resistant film such as glass, plastic or the like. A further modification of the invention comprises the construction of cylindrical elements with spiral paths therethrough.
