摘要： A heat exchanger is constructed by tubes, corrugated fins and head pipes, which are assembled together. Herein, the tube is constructed by bending a flat plate whose surfaces are clad with brazing material to form a first wall and a second wall, which are arranged opposite to each other with a prescribed interval of distance therebetween to provide a refrigerant passage. Before bending, a number of swelling portions are formed to swell from an interior surface of the flat plate by press. By bending, the swelling portions are correspondingly paired in elevation between the first and second walls, so their top portions are brought into contact with each other to form columns each having a prescribed sectional shape corresponding to an elliptical shape or an elongated circular shape each defined by a short length and a long length. The columns are arranged to align long lengths thereof in a length direction of the tube corresponding to a refrigerant flow direction such that obliquely adjacent columns, which are arranged adjacent to each other obliquely with respect to the length direction of the tube, are arranged at different locations and are partly overlapped with each other with long lengths thereof in view of a width direction perpendicular to the length direction of the tube. The tubes, corrugated fins and head pipes are assembled together and are then placed into a heating furnace to heat for a prescribed time.

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.

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.
