Abstract
Provided is a technique to achieve equalization of stress in a heat exchange core. The heat exchange core which performs heat exchange between a first fluid and a second fluid includes a circular first cross-section in which a first flow path group for the first fluid and a second flow path group for the second fluid are positioned. First flow paths included in the first flow path group and second flow paths included in the second flow path group are annularly arranged in the first cross-section. The first flow path group and the second flow path group are concentrically arranged as a whole in the first cross-section. Each of the first flow paths and the second flow paths is divided into a plurality of sections in a circumferential direction of the heat exchange core.
