Abstract
A heat exchanger includes a pair of opposed, spaced apart heat exchanger plates defining a heat exchanger volume therebetween having an inlet and opposed outlet. A plurality of heat exchanger ribs are included within the heat exchanger volume. Each rib defines a rib body spanning the heat exchanger volume. Each rib body includes a plurality of slits therethrough to define a flow path through the heat exchanger ribs from the inlet to the outlet of the heat exchanger volume. The ribs and slits can be formed using ultrasonic additive manufacturing (UAM), for example.

A heat exchanger comprising:
- a pair of opposed, spaced apart heat exchanger plates defining a heat exchanger volume therebetween having an inlet and opposed outlet;
- and
- a plurality of heat exchanger ribs within the heat exchanger volume, each rib defining a rib body spanning the heat exchanger volume, each rib body including a plurality of slits therethrough to define a flow path through the heat exchanger ribs from the inlet to the outlet of the heat exchanger volume,
- wherein the slits in each rib define a rectangular array of slits and wherein the rectangular array includes twelve substantially rectangular slits longitudinally aligned in a four by three array four slits wide along a direction defined by long sides of the substantially rectangular slits, wherein each rib includes a plurality of additive manufacturing layers aligned with a flow direction defined through the slits thereof.
