A heat exchanger includes an outer tube having a first axial end and a second axial end, and a pressure barrier tube positioned generally concentric to and within the outer tube such that a first flowpath is defined axially through at least a portion of the outer tube and radially between the outer tube and the pressure barrier tube. A second flowpath is defined within and at least partially axially through the pressure barrier tube. The heat exchanger also includes a first plurality of fins coupled to and extending between the outer tube and the pressure barrier tube, through the first flowpath, and a second plurality of fins coupled to and extending radially inward from the pressure barrier tube, through the second flowpath. A first fluid in the first flowpath exchanges heat with a second fluid in the second flowpath via heat transfer through the first plurality of fins, the pressure barrier tube, and the second plurality of fins.
