    Patent number: 11614287
    Abstract: A heat exchanger includes a plurality of tube assemblies. Each tube assembly includes an inner tube extending within an outer tube and configured for the flow of a first fluid therein. The inner tube and the outer tube are sized to facilitate capillary action fluid flow of a second fluid in an annular space between an outer surface of the inner tube and an inner surface of the outer tube, facilitating indirect heat exchange of the second fluid, through the inner tube and indirect heat exchange of the second fluid through the outer tube.
