Tube in cross-flow conduit heat exchanger

A heat exchanger comprising:

• an input cavity defined by inlet cavity walls;
• a heat exchanger portion in fluid communication with the input cavity and defined between a first side and a second side, wherein a plurality of baffles are positioned within the heat exchanger portion;
• and
• an outlet cavity in fluid communication with the heat exchanger portion and defined by outlet cavity walls;
• wherein the heat exchanger portion comprises:
• a plurality of first fluid paths defined between the baffles and extending from the input cavity to the outlet cavity;
• and
• a plurality of tubes extending through the heat exchanger portion from the first side to the second side, wherein each tube extends through the baffles so as to define a second fluid path through the heat exchanger portion;
• wherein at least one baffle is defined by a laminate wall comprising a layered, composite material.
