A heat exchange system having at least one closed compartment containing in a first portion a first liquid having a first temperature at or near the first liquid's boiling point; a first thermally conductive conduit, containing a first fluid having a second temperature higher than the first temperature, submerged in the first liquid, causing at least a portion of the first liquid to absorb latent heat and boil within the at least one closed compartment, and convert to vapors; and a second thermally conductive conduit, containing a second fluid having a third temperature lower than the first temperature, passing through a second portion of the at least one closed compartment where the vapors contact the second thermally conductive conduit containing the second fluid, causing the vapors to lose latent heat and condense, and join the first liquid in the first portion of the at least one closed compartment.
