  • Heat Exchanger Element And Method of Production
    Publication number: 20160146549
    Abstract: A method for producing a heat exchanger element for a heat exchanger, in particular for a recuperator or the like, and to a heat exchanger element, includes a substantially carbon body infiltrated with pyrolytic carbon. The heat exchanger element forms a first contact surface in a first flow channel of the heat exchanger and a second contact surface in a second flow channel of the heat exchanger.
