摘要： There is provided a heat exchanger 10 in which each of header tanks 20A and 20B is configured so that each of intermediate plates 60 and 90 is held between a header plate 40 and a tank plate 50. The intermediate plate 60, 90 functions as a reinforcing member, so that the strength of the header tank 20A, 20B is improved. The intermediate plate 60, 90 serving as a reinforcing element comprises bent parts 100 between the central portion and both the end portions in the width direction of the header tank 20A, 20B. By the elastic deformation of the bent parts 100, for example, the stresses developed in brazing of the header tank 20A, 20B, and the stresses at the time when a refrigerant pressure is applied can be prevented from concentrating in the joint portion of the header plate 40, the tank plate 50, and the intermediate plate 60, 90.

摘要： A flat or a flared tubular end portion devoid of dimples is provided at the end of a tube 11 which is to be inserted into a header with the length, of the flat tubular portion being 1.5 mm or less along the direction of the length of the tube to prevent rapid reduction and enlargement of the cross-sectional area of the refrigerant path in the vicinity of the joint of the tube and the header, so as to reduce the pressure loss of the refrigerant which flows in and out from the header to the tube. A tube insertion stop is also provided consisting either, of a cut formed in the longitudinal edge of the flat end portion or a guard member which is formed aft of the flared, end portion so as to abut the header and seal off the tube insertion aperture of the header.

摘要： A heat exchanger employing a dimple tube is disclosed, in which sufficient strength is provided by improving the processing accuracy of the dimple tube and decreasing the processing error. The tube comprises a plate folded in two so as to make two edges of the plate contact each other and form a flat tube. The plate comprises protrusions provided on each inner wall of the flat tube in a manner such that the heads of opposed protrusions on both the inner walls contact each other. The plate is clad with a brazing filler metal and the protrusions are formed on a surface of the plate before the plate is folded, and the two edges of the plate and the heads of the opposed protrusions are respectively brazed after the plate is folded. A predetermined number of sets of the opposed protrusions, positioned closest to the end of the tube, are larger than the other protrusions in a manner such that their size along the longitudinal direction of the tube is larger.
