- the constricted portion is tightly fitted with the copper tube, so that the length of the copper tube extending into the bushing is controllable, that is, the constricted portion can play a better role in positioning the copper tube.
- the constriction portion is in the shape of a curved surface that is gradually contracted from an end connected to the bushing to an end away from the bushing. This arrangement facilitates the processing and forming of the constricted portion.
- the length S of the constricted portion along the axial direction of the bushing satisfies: S ⁇ 0.5 mm.
- the middle portion of the intermediate segment shrinks toward the center of the intermediate segment to form a recessed portion, and the recessed portion divides the intermediate segment into a first segment and a second segment that are connected.

- the solder used to solder the copper tube and bushing can be placed between the copper tube and the flange.
- the solder melts in the space between the copper tube and the flange, and then penetrates down into the gap between the bushing and the copper tube to complete the welding of the copper tube and the bushing. Due to the presence of the flange, the solder will not overflow the gap between the copper tube and the bushing.
