    摘要： A heat exchanger includes a first header (20), a second header (22), and a core (24). The first header includes a fluid inlet (28). The second header is positioned downstream of the first header with respect to a first flow path of a first fluid. The second header includes a fluid outlet (30). The core extends from the first header to the second header. The core includes a plurality of tubes (32). The heat exchanger also includes a first region (60) which is at a higher temperature than regions adjacent to the first region. The first region is made of a first mixture of materials in a first ratio. The first mixture of materials causes a coefficient of thermal expansion in the first region to be lower than coefficients of thermal expansion in the regions adjacent to the first region.

    摘要： 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 is greater than 0 and less than or equal to 1.25 0 T f T m ≤ 1.25 .; 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 to define a unit cell (132, 132a) performance factor (UCPF).
