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： An object of the present invention is to provide a finned tube heat exchanger in which cut-and-raised parts ensure improved drainage and an enhanced heat transfer effect.
The finned tube heat exchanger (1) of the present invention is provided with heat-transfer fins (2) and a plurality of heat-transfer tubes (3). The heat-transfer fins are disposed along an airflow. The plurality of heat-transfer tubes is inserted into the heat-transfer fms and arranged in a direction substantially orthogonal to the airflow direction. A plurality of cut-and-raised parts (21 a to 21f) is formed in the heat-transfer fins by cut-and-raise machining, the parts being straightly aligned from the upstream side toward the downstream side in the airflow direction on two sides, as viewed in a perpendicular direction, of the heat-transfer tubes. Straight lines (L1, L2) that connect the plurality of cut-and-raised parts are sloped relative to the airflow direction so that the airflow in the vicinity of the heat-transfer tubes is guided to the rearward side of the heat-transfer tubes in the airflow direction. Concavities (24) are formed in the heat-transfer fins on the periphery of the heat-transfer tubes at least in a part below a horizontal plane that passes through a center axis of the heat-transfer tubes.摘要翻译： 本发明的目的是提供一种翅片管式热交换器，其中切割和升高的部件确保改善的排水和增强的传热效果。 本发明的翅片管式热交换器（1）设有传热翅片（2）和多个传热管（3）。 传热翅片沿气流设置。 多个传热管被插入到传热部件中并且布置在与风向大致正交的方向上。 通过切割加工在传热翅片上形成多个切起部（21a〜21f），该部分在气流方向上从上游侧向下游侧直线对准 在垂直方向上观察传热管的侧面。 连接多个切起部的直线（L1，L2）相对于气流方向倾斜，使得传热管附近的气流被引导到传热管的后侧 在气流方向。 至少在通过传热管的中心轴的水平面下方的部分，在传热管的周边的传热翅片上形成凹部（24）。

摘要： Water drainage between louvers is improved. Fins (50) have a plate-shaped part (60) positioned so that a plate-thickness direction intersects an air-flow direction (F), and have a plurality of louvers (61) protruding from the plate-shaped part (60) in the plate-thickness direction. Flat heat-transfer tubes (41, 42, 43...) are inserted into the fins (50) so as to intersect the air-flow direction (F). In particular, the louvers (61) have a first louver (62) and a second louver (63) that have different inclination angles with respect to the plate-shaped part (60). These louvers (62, 63) are positioned in alternation.

摘要： The present invention provides a heat exchanger having enhanced drainage performance with respect to condensed dew. In a heat exchanger (10), first cutting line segments (121) and second cutting line segments (122) are set in a material of wavy fins (12) of a pre-wavily folded state. Each first cutting line segment (121) intersects with a hypothetical center line (X) in a folded portion. Each second cutting line segment (122) intersects with the hypothetical center line (X) while being extended from a vicinity of a terminal of each first cutting line segment (121). When the material is folded, at least acute triangle portions are raised, each of which is formed by each first cutting line segment (121) and each second cutting line segment (122). Accordingly, cut-and-raised portions (12b) are formed. Distance from the base to the apex of each cut-and-raised portion (12b) is longer than that in the well-known heat exchanger. Therefore, the contact amount is increased between the cut-and-raised portions (12b) of the wavy fins (12) on given two vertically adjacent tiers. Consequently, condensed dew easily flows along the cut-and-raised portions (12b) and drainage performance is enhanced.

摘要： A pressure loss is reduced by providing a plurality of rows of grooves (3) arranged in V-shaped patterns on an inner surface of a pipe body (1a) so as for the rows of grooves to be symmetric with respect to the pipe axis direction and by forming secondary grooves (6), (7) in a prescribed depth in part of projected portions (5) formed therebetween. Also, even when a refrigerant flow rate is low, the refrigerant flow in the pipe can be appropriately controlled by making widths of the plurality of rows of the grooves (3) arranged in the V-shaped patterns unequal in the circumferential direction to generate swirl in the spiral direction and thereby a heat transfer performance is improved as much as possible.
