摘要: This heat exchanger comprises: a pair of plates that face each other; and an inner fin which is provided between the plates and in which a fluid circulates. The inner fin has a plurality of offset fins which are arranged side by side in the flowing direction of the fluid and are provided such that the positions thereof are mutually offset in the width direction orthogonal to the flowing direction. The offset fins include: plate joint parts which are joined to the plates and have steps formed in the flowing direction; fin parts provided along the opposing direction of the plates and connected to the plate joint parts; and reception slopes which are provided to the plate joint parts obliquely to the flowing direction and which receive the fluid from the steps.

摘要: This fin comprises a plate-shaped substrate part (10) having a heat transfer tube passing part, which is a circular shape centered on a central axis C and through which a heat transfer tube passes, and a louver part at which a first slit is formed by a first louver (21). The louver part has a flat section (16), the first louver (21) that is provided on the downstream side of the flat section (16) and protrudes more in the Z-axis direction than the flat section (16), and a second louver (22) that is provided on the downstream side of the first louver (21). The second louver (22) has a linear part (22b) at which the shape of the cross-section thereof when cut in the XZ plane is linear, a second louver upstream part (22a) bending obliquely in the upstream direction from the upstream end of the linear part (22b) and extending linearly, and a second louver downstream part (22c) bending obliquely in the downstream direction from the downstream end of the linear part (22b) and extending linearly. The linear part (22b) is disposed so as to overlap with the heat transfer tube passing part when viewing the cross-section.

摘要: Provided is a heat exchanger that can, even when frosting occurs on an upwind side of the heat exchanger, exchange heat continuously on a downwind side of a fin by securing a ventilation path, and in addition, further improve drainage of the melt water. The heat exchanger (10) of the present invention includes a plurality of tubes (21) each having a refrigerant flowpath (21a) through which a refrigerant flows and a corrugated fin (22) including a plurality of heat transfer walls (23) that are arranged in a running direction of the tubes (21) and span from one to the other of adjacent tubes among the plurality of tubes (21), the fin being capable of exchanging heat with the tubes (21). Each of the heat transfer walls (23) includes a heat transfer piece (23R(L)) leading to a leading edge portion (23a) positioned on the upwind side of a passing airflow (A) and a leading edge portion (23b) indented toward the downwind side in the direction of the airflow A relative to the leading edge portion (23a). A first heat transfer piece is disposed on every other layer of the arrangement on both of a side closer to one tube (21) and a side closer to the other tube (21) of adjacent tubes among the plurality of tubes such that first heat transfer piece appears alternately on both sides.
