Description of the Related Art As a heat exchanger used for an air conditioner, a cross fin type heat exchanger in which a large number of plate-shaped fins orthogonal to a plurality of heat transfer tubes arranged in parallel are arranged is often used. Are known. In a heat exchanger having such a configuration, when arranging a plurality of rows of heat transfer tubes in the air flow direction, in order to make the heat transfer tubes orthogonal to the plate fins, all the heat transfer tubes must be parallel, but the upstream side When the heat transfer tubes on the downstream side are arranged in the dead water region formed behind the heat transfer tubes arranged on the lower side, heat transfer in the heat transfer tubes on the downstream side may be reduced. Therefore, in the case of a cross-fin type heat exchanger, the heat transfer tube arrangement is arranged in a staggered arrangement in the air flow direction so that the transfer tubes arranged on the downstream side are not affected by the dead water area of the transfer tubes arranged on the upstream side. Is being done. However, in the case of the cross-fin type heat exchanger, the heat transfer tubes are inserted orthogonally to the plate-shaped fins, so there is a limit to downsizing the heat exchanger while maintaining heat exchange performance. was there.

しない場合がある。By the way, in the case of a mesh fin type heat exchanger, a large number of mesh fins are joined to the outer periphery of a plurality of heat transfer tubes arranged in parallel to each other in parallel to the tube axis. Although it is possible to form a miniaturized multi-row heat exchanger by polymerizing a plurality of single modules (i.e., heat exchange modules), it is necessary to simply polymerize a plurality of heat exchange modules as described above. As described above, the dead water region generated behind the heat transfer tube in the upstream heat exchange module is affected by the heat transfer tube and the fins in the downstream heat exchange module, and the heat exchange performance may not necessarily be improved.
