Recuperator, heat exchange channel extending transverse to main flow direction

摘要

A recuperator according to the present invention is disposed at least on a recuperator unit having heat exchange channels extending in parallel with each other, and a first side surface of the recuperator unit, and the first surface of the recuperator unit heat-exchanges the recuperator unit. A first header portion having a triangular cross section connected to the first end of the channel and a first surface of the first header portion disposed on the second side surface of the recuperator unit to exchange heat with the recuperator unit; A second header portion having a triangular cross-section connecting to the second end of the channel, a supply duct portion extending to the second surface of the first and second header portions, and the first and second A discharge duct portion extending from the third surface of the header portion, and the supply duct portion and the discharge duct portion extend in a transverse direction in the longitudinal direction of the heat exchange channel, and the supply duct portion and the discharge duct DOO portion extends on the surface of the header portion which is disposed opposite to the recuperator unit.
