摘要： In a heat exchanger (23), a principal windward heat exchange region (35) includes a principal windward bank portion, a principal leeward heat exchange region (65) includes a principal leeward bank portion, an auxiliary windward heat exchange region (37) includes an auxiliary windward bank portion, and an auxiliary leeward heat exchange region (67) includes an auxiliary leeward bank portion. Each of the principal and auxiliary bank portions is constituted of a plurality of flat tubes. In the heat exchanger (23) functioning as an evaporator, a refrigerant flows sequentially through the auxiliary windward, auxiliary leeward, principal leeward, and principal windward bank portions. In the heat exchanger (23) functioning as a condenser, a refrigerant flows sequentially through the principal windward, principal leeward, auxiliary leeward, and auxiliary windward bank portions. Consequently, the heat exchanger exhibits performance sufficient for functioning as both an evaporator and a condenser.

摘要： A heat exchanger (23) includes a plurality of principal heat exchange sections (51a-51c) and auxiliary heat exchange sections (52a-52c). A first header-collecting pipe (60) includes an upper space (61) communicating with flat tubes (33) of all of the principal heat exchange sections (51a-51c). Each of the auxiliary heat exchange sections (52a-52c) is in series connection to a corresponding one of the principal heat exchange sections (51a-51c). Of tube number ratios of the number of the flat tubes (33) constituting each of the heat exchange sections (51a-51c) to the number of the flat tubes (33) constituting a corresponding one of the auxiliary heat exchange sections (52a-52c), the first principal heat exchange sections (51a) which is the lowermost one has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section (51a) is accelerated during defrosting, thereby shortening the time required for defrosting.

摘要： The present invention provides a heat exchanger and an air conditioning apparatus with which it is possible to minimize unevenly distributed flow of refrigerant and to minimize reverse current of the refrigerant flowing from the ascending space toward the descending space even in cases of use under conditions such that the circulation rate of the refrigerant varies. An outdoor heat exchanger 20 has a folding-back header 24 in which an ascending space 61b to which a plurality of flat perforated tubes 21b are connected and a descending space 62b are partitioned while communicating via an upper communication port 73 and a lower communication port 72. Within the folding-back header 24, the ascending space 61b and a first guide space 61a are partitioned while communicating vertically via an ascending opening 82a, 82b. When the heat exchanger is viewed from above after having been installed, the ascending opening 82a, 82b and the plurality of flat perforated tubes 21b have an area of overlap, but there is substantially no overlap between the ascending opening 82a, 82b and a space where the lower communication port 72 is extended in the direction in which the flat perforated tubes 21b extend.

摘要： Provided are a heat exchanger and an air conditioning device with which it is possible to minimize eccentric flow of a refrigerant, even in cases of use under conditions in which the circulation rate varies. A plurality of flat perforated tubes (21b) are connected at different heights to a first internal space (23a) of a doubled-back header collecting tube (23) of an outdoor heat exchanger (20). In the first internal space (23a) there is adopted a loop structure including a first partition plate (51), first inflow ports (41x), a first upper communicating passage (51x), and a first lower communicating passage (51y). The first partition plate (51) partitions the first internal space (23a) into a first outflow space (51a) and a first loop space (51b). The first inflow ports (41x) are disposed at the bottom of the first outflow space (51 a), so as to cause the refrigerant to ascend within the first outflow space (51 a). Refrigerant that has reached the top end of the first outflow space (51 a) is guided into the first loop space (51b) via the first upper communicating passage (51x), and refrigerant having descended through the first loop space (51b) is returned to the first outflow space (51 a) via the first lower communicating passage (51y), in a direction other than a vertical direction.

摘要： Disclosed is an outdoor heat exchanger in which a first principal communication space (75a) that communicates with an upstream side of a plurality of flat tubes (31) when the outdoor heat exchanger functions as an evaporator is provided with a partition plate (91). The partition plate (91) extends in a vertical direction, and divides the first principal communication space (75a) into a first space (93) which communicates with the plurality of flat tubes (31), and a second space (94) which communicates with a branch pipe portion (112a) for introducing a refrigerant into the first principal communication space (75a) when the outdoor heat exchanger functions as an evaporator. A through hole (91a) allowing the first space (93) and the second space (94) to communicate with each other is formed at a lower portion of the first principal communication space (75a).
