Claim 3:
4. A bulkhead heat exchanger comprising:
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 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 a plurality of wall surfaces,
the plurality of wall surfaces conform to sine curves different in position from each other, respectively,
each of the plurality of flow path walls is divided into a plurality of flow path wall elements by forming a plurality of notches at each period of the sine curves, the plurality of notches overlapping inflection points of the sine curves, and
each of the plurality of flow path wall elements overlaps with either maximum points or minimum points of the sine curves, and is further divided by forming an in-element notch overlapping another inflection point of the sine curves which is different from the inflection points where the notches overlap, each of the plurality of flow path wall element including an intermediate flow path wall element disposed in the in-element notch.
