Abstract
A heat exchanger having a plurality of coaxially aligned chambers for providing radiant, thermal heat transfer between a plurality of separately contained fluids within a single unit and a helical tube having at least one portion positioned within at least one of the chambers. A first, second, third, and fourth chambers are in coaxial alignment. The heat exchanger heats a cryogenic liquid to a gas phase using four different heat transfer fluids in one contained unit without mixing any of the fluids in the exchanger, thus reducing the size and cost, while increasing the efficiency of the heat exchanger.
