A bulkhead heat exchanger includes path walls which divide a space formed between a first bulkhead and a second bulkhead into first paths. The first bulkhead and the second bulkhead separate the first paths from second paths. When a phase overlapping an inflection point of one path wall of adjacent path walls is θ0 (=0°), the path wall is a sinusoidal path wall having a range of θ0 (=0°)<θ1<θ2<90°<θ3<θ4<180°<θ5<θ6<270°<θ7<θ8<θ0 (=360°) as one period. In the one path wall, a main element is formed in θ1≤θ<θ3 and θ6≤θ<θ8, and in the other path wall, a main element is formed in θ2≤θ<θ4 and θ5≤θ<θ7.

Bulkhead heat exchanger

A bulkhead heat exchanger includes a first bulkhead, a second bulkhead, and a plurality of flow path walls which divide a space formed between the first bulkhead and the second bulkhead into a plurality of first flow paths, wherein the first bulkhead and the second bulkhead separate the plurality of first flow paths from a plurality of second flow paths through which a second fluid different from a first fluid flowing through the plurality of first flow paths flows, the plurality of flow path walls have the plurality of wall surfaces, and the plurality of wall surfaces conform to sine curves different from each other, respectively.
