PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving heat exchange efficiency while restraining increase in the size and the weight of the heat exchanger.

SOLUTION: A heat exchanger 100 includes a flow passage layer 10 in which a first flow passage 11 having a tubular shape extending in a first direction so that a first fluid 1 flows therethrough and a second flow passage 12 having a tubular shape extending in a second direction intersecting with the first direction so that a second fluid 2 exchanging heat with the first fluid 1 flows therethrough are arranged in a same layer. Each of the first flow passage 11 and the second flow passage 12 is formed in such a manner that a flow passage cross sectional area is reduced and enlarged along a direction in which the flow passage extends. By displacement of first portions 23, 33 having the reduced flow passage cross sectional area in Z direction which intersects with the first direction and the second direction, the first flow passage 11 and the second flow passage 12 intersect with each other at the first portions 23, 33 in the same layer.

【課題】熱交換器のサイズおよび重量の増大を抑制しながら、熱交換効率を改善させることが可能な熱交換器を提供する。
【解決手段】この熱交換器100は、第1方向に延びる管状形状を有し、第1流体1を流通させる第1流路11と、第1方向と交差する第2方向に延びる管状形状を有し、第1流体1と熱交換する第2流体2を流通させる第2流路12と、が同一層内に配置された流路層10を備える。第1流路11および第2流路12の各々は、流路の延びる方向に沿って流路断面積が縮小および拡大するように形成されている。第1流路11および第2流路12は、流路断面積が縮小された第1部分23、33が第1方向および第2方向と交差するZ方向に変位することにより、第1部分23、33において同一層内で交差している。
