Abstract
A tube and shell heat exchanger is formed by a shell enclosing an internal sidewall which in turn receives an internally located flow controller outer and inner heat exchange cavities are formed between the outer shell and the internal shell and the internal shell and the flow controller, respectively. Helical convolutions of the conduit are provided in each of the heat exchange cavities for counter concurrent flow of fluid medium from one cavity to another. A bottom wall closes off the outer shell.
