摘要： In a center portion of the coupling body of a bite type pipe coupling, an insertion port for receiving a connector pipe is formed at an end that faces a coupling member. In the center portion, an insertion port is formed at an end located opposite to the end that faces the coupling member. An apparatus-side pipe is inserted into and brazed to the insertion port. A thin wall portion is formed in an outer circumferential wall portion of the entrance of the insertion port for receiving the apparatus-side pipe. The outer diameter of the thin wall portion is smaller than that of the coupling body. The thin wall portion is formed in a range extending from the entrance of the insertion port to a position that is located closer to the entrance than the inner end of the insertion port and is located in the vicinity of the inner end.

摘要： The present invention provides a heat exchanger, an air conditioning apparatus, and a method for manufacturing the heat exchanger capable of reducing the scattering of condensate water from curved portions to the downstream side in the direction of airflow. An indoor heat exchanger (10) comprises lower fins (30) and upper fins (40). The upper fins (40) are inclined at an angle, formed by the longitudinal direction in relation to the vertical direction, so that the angle in the direction of the airflow (F) is equal to or greater than the angle of the lower fins (30), and the upper fins are disposed adjacent to the top ends of the lower fins (30). The upper fins (40) have curved portions (R) that are curved in proximity to the portions bordering the top ends of the lower fins (30) on the downstream side in the airflow direction F.

摘要： It is an object to raise heat exchange efficiency. A heat exchanger-use fin (1) is a fin attached to heat transfer tubes and is equipped with a fin body (11), a plurality of collars (13) and erect portions (14). The fin body (11) extends in a predetermined direction (91), and plural holes (12) into which the heat transfer tubes are inserted are disposed in the fin body (11) along the predetermined direction (91). The collars (13) are erected surrounding the holes, such that one collar surrounds each hole, on the same side with respect to the fin body (11). When the heat exchanger-use fin (1) is seen from the collars (13) side, the collars (13) are all disposed between two straight lines (101, 102) that extend along the predetermined direction (91) on a surface (111) of the fin body (11), and outer peripheries (131) of the collars (13) contact the two straight lines (101, 102). The erect portions (14) are erected on the fin body (11) on the same side as the collars (13) and are positioned outside the two straight lines (101, 102). Distal ends (141) of the erect portions (14) are in higher positions than distal ends (132) of the collars (13) when seen from the surface (111).

摘要： An air conditioner indoor unit A includes a body casing 1, which accommodates a fan 2 and a heat exchanger 3. A top plate 13 is arranged in an upper portion of the body casing 1. A longitudinal reinforcement rib 14, which divides the top plate 13 into a first region 13a and a second region 13b, is formed in the top plate 13. A first lateral reinforcement rib 15, which extends between the longitudinal reinforcement rib 14 and a corresponding one of side edges 13c of the top plate 13, is formed in the first region 13a. A second lateral reinforcement rib 16, which extends between the longitudinal reinforcement rib 14 and the other side edge 13c of the top plate 13, is formed in the second region 13b. The reinforcement ribs 14, 15, 16 thus significantly increase the rigidity of the top plate 13 as a whole. Further, if the first and second lateral reinforcement ribs 15, 16 are formed by stretch-forming, torsion and flexure of the top plate 13 caused by spring back after the ribs 15, 16 are formed are decreased. As a result, the top plate 13 is mounted with increased work efficiency.
