1. A recuperator, comprising:
at least a first recuperator unit with heat-exchanging channels extending parallel to each other; a first header placed on a first side of the recuperator unit and having a triangular cross-section, one surface of which connects to a first end of the heat-exchanging channels of the recuperator unit; a second header placed on the second side of the recuperator unit and having a triangular cross-section, one surface of which connects to the second side of the heat-exchanging channels of the recuperator unit; supply ducts extending to a second surface of the first and the second header; and discharge ducts extending from the third surface of the first and the second header, wherein the supply ducts and the discharge ducts extend transversely of the longitudinal direction of the heat-exchanging channels, wherein the supply ducts and the discharge ducts extend on the sides of the headers lying opposite the recuperator units, the passage of the supply ducts decreases in the flow direction, and the passage of the discharge ducts increases in the flow direction. |
