Abstract
A two-pass heat exchanger with calibrated bypass is disclosed for cooling heat-generating substrates and/or for heating a heat transfer fluid. The heat exchanger has first and second outer plate walls and an intermediate plate wall located between and spaced from the outer plate walls in the thickness dimension of the heat exchanger, and with inlet and outlet ports at the same end. An input flow passage is defined between the first outer plate wall and the intermediate plate wall, and a return flow passage is defined between the second outer plate wall and the intermediate plate wall. The first and second fluid flow passages are in a U-flow, stacked arrangement. At least one bypass opening extends through the intermediate plate wall between the input and return flow passages, and configured to permit a portion of the heat transfer fluid to bypass portions of the input and return flow passages.
