Abstract

An heat exchanger (20) and method for forming the heat exchanger (20), the heat exchanger (20) including a cooling architecture (122) comprising at least one unit cell (132, 132a) having a set of walls (138) with a thickness, the set of walls (138) defining fluidly separate conduits (124, 124c, 124h) having multiple openings (140, 140a, 140b), each of the multiple openings (140, 140a, 140b) having a hydraulic diameter; wherein an average fluid temperature (T<f>) to material temperature limit (T<m>) ratio T f T m <img class="EMIRef" id="2e8a0b31-d583-4eb0-aed8-a28944b31404-ia01" /> is greater than 0 and less than or equal to 1.25 0 < T f T m ≤ 1.25 <img class="EMIRef" id="2e8a0b31-d583-4eb0-aed8-a28944b31404-ia02" /> .; and wherein the thickness (t) and the hydraulic diameter (D<H>) relate to each other by an equation: T f T m ⋅ D H 2 3 D H + t D H + 2 t 8 3 <img class="EMIRef" id="2e8a0b31-d583-4eb0-aed8-a28944b31404-ia03" /> to define a unit cell (132, 132a) performance factor (UCPF).
