ABSTRACT:
A heat exchanger for heating or cooling a liquid, comprises a stationary outer shell and an drum rotatable coaxially in the shell. The outer periphery of the drum is adjacent the inner periphery of the shell and a stationary heat exchanger is disposed within the drum. Liquid to be heated or cooled is fed into the drum past the stationary heat exchanger and then between the outer periphery of the drum and the inner periphery of the shell. Impeller structure is disposed on [the] and extends axially along the outer periphery of the drum, such as a helicoidal vane, to [more] move the liquid is a circuitous path along the inner periphery of the stationary shell upon rotation of the drum.
