Disclosed herein is a novel, adjustable heat exchanger 100 for reliably exchanging heat from a hot working fluid to a transfer fluid. The working fluid passes through an inlet plenum 110, at least one conduit 133 that may be a tube or a plurality of tubes, and out of an outlet plenum 150. A chamber wall 132 encloses the conduits 133 creating a central chamber 130 having interstitial spaces 139 around the conduits 133. A transfer fluid passes through the interstitial spaces in a direction substantially opposite the working fluid, absorbing heat from the conduits 133. A bypass 180 fluidically connects the transfer fluid source 170 to central chamber 130 proximate the inlet plenum 110. Cool transfer fluid bypasses a portion of the central chamber and is provided directly to the central chamber 130 proximate the inlet plenum 110 to cool structures there and reduce heat failures, while providing a constant flow of transfer fluid out of the heat exchanger 100.
