    摘要： An object described in the present disclosure is to provide a heat exchanger, a heat exchange unit, and a refrigeration cycle apparatus, in which an insertion hole of a header and an end portion of a heat exchange member can be properly joined to each other, and also provide a method of manufacturing the heat exchange member. In the heat exchanger, the heat exchange unit, and the refrigeration cycle apparatus, and the method of manufacturing the heat exchange member, the heat exchange member and a header are provided. The heat exchange member extends in a first direction, and the header is connected to an end portion of the heat exchange member in the first direction. The heat exchange member includes at least one heat transfer tube extending in the first direction and a fin that is formed at part of an end edge of the at least one heat transfer tube in a second direction perpendicular to the first direction. The fin is provided at a fin setting portion that is at least part of a remaining portion of the heat exchange member that is other than the end portion thereof. Part of the at least one heat transfer tube that is located at the end portion of the heat exchange member has a smaller width in the second direction than a width of part of the at least one heat transfer tube in the second direction that is located at the fin setting portion.

    摘要： A helical fractal heat exchanger (10) comprises a heat exchanger core (12) defining a plurality of helical, first fluid conduits (32) arranged in a two-dimensional grid configuration, and plurality of helical, second fluid conduits (38) in thermal communication with the first fluid conduits (32). A first fluid inlet structure (14) splits a first fluid from a first fluid inlet (16) of the heat exchanger (10) and supplies it to each of the plurality of first fluid conduits (32), and a first fluid outlet structure (18) recombines the first fluid from the plurality of first fluid conduits (32) and conveys it to a first fluid outlet (20) of the heat exchanger (10). The first fluid inlet and outlet structures (14, 18) are each fractal structures comprising at least two multi-furcation stages (42, 48, 56, 58) in which a parent channel (44, 50) divides into two or more sub-channels (46, 52) that diverge away from each other.
