径を０．３〜０．６mm拡管してフィンとパイプを固定し
てフィンチューブを製作する。Generally, a fin-tube type heat exchanger such as a room air conditioner and a refrigerator is composed of a pipe 2 for flowing a refrigerant, fins 1 for radiating or absorbing heat, a side plate 4 for mounting and fixing the heat exchanger, and the like. The method of manufacturing the evaporator for the refrigerator shown in FIG. 1 is to arrange the small standard fins 1 at a predetermined position for arranging fins having a large number of grooves, and then to put two straight pipes 2 into the pipe insertion holes of the fins. Insert and expand the outer diameter of the pipe by 0.3 to 0.6 mm to fix the fin and the pipe to manufacture a fin tube.

The side plate fixing pipe 13 bent in a meandering shape in advance is set in the side plate fixing pipe U groove 6 provided in the side plate 4, and the U groove 6 is formed.
The side plate 4 can be fixed to the heat exchanger only after the caulking grooves 7 on both sides of the are caulked. In the side plate fixing method as described in 2, the side plate fixing pipe 13 is necessary, and it is very difficult to secure the dimension between the side plates. Furthermore, even if the side plate 4 is inserted into the bent portion 3 of the heat exchanger, there is a problem that the side plate 4 falls off from the heat exchanger before the caulking of the side plate fixing pipe in the next step.
本発明の目的は側板固定パイプの無い構造の熱交換器で
もパイプと側板が固定できる側板固定技術を提供するも
のである。An object of the present invention is to provide a side plate fixing technique capable of fixing a pipe and a side plate even in a heat exchanger having a structure without a side plate fixing pipe.

る。An embodiment of the present invention will be described below with reference to FIGS. 4 to 9. The pipe insertion hole 5 of the side plate 4 shown in FIG. In this example, the side plate 4 and the heat exchanger are assembled by inserting the two side plates 4 on both sides of the heat exchanger fin row and then setting the flange upright so as to close the pipe insertion hole 5. By bending back substantially the center of the raised portion 8 or the straight portion 10 thereof, the pipe 2 is caulked and bent by the deformation of the periphery of the pipe insertion hole 5 in the portion of the side plate 4 provided with the plurality of small elongated holes 9. Since the flange rising portion 8 or the side plate 4 that has been returned does not come off, it is securely fixed.

By closing the hole of the pipe insertion hole 5, it is possible to prevent the airflow cooled by the fins from leaking and improve the performance. Further, the elongated hole 9 around the elongated hole-shaped pipe insertion hole 5 provided with the flange rising portion 8 may be a round hole, a square hole or the like, and the bending of the flange rising portion 8 can be formed with a small force so that the pipe 2 and the side plate can be formed. It suffices if 4 can be fixed.

入孔周辺を変形させ、パイプ２と側板４を固定できる。In still another embodiment, the pipe insertion hole 5 of the side plate 4 shown in FIG. 7 is formed by expanding and raising the flange rising portion 11 and forming a plurality of small elongated holes 9 around the pipe insertion hole 5.
Is an example in which is provided. After inserting and setting the side plate 4 shown in FIG. 7 into the pipe bending portion 3 of the pipe bent in a meandering shape, the flange rising portion 11 is bent and unbent at a substantially central portion to make a plurality of small holes 9 in the side plate 4. It is possible to fix the pipe 2 and the side plate 4 by deforming the area around the pipe insertion hole in the portion provided with.

板の薄板化ができる。According to the present invention, since the substantially central portion of the flange rising portion of the side plate is bent back so as to close the pipe insertion hole in which the bending portion is inserted, the inserted pipe is caulked by deformation around the pipe insertion hole. The bent and bent back flange prevents the bent portion of the pipe from coming off the side plate and is securely fixed. Moreover, since the pipe insertion hole is closed by the bent back flange, leakage of the air flow cooled by the fins can be prevented, and the performance of the heat exchanger is improved. In addition, since multiple long holes are provided around the pipe insertion hole, a pipe bent in a multi-point meandering shape has different dimensions, shapes, etc. depending on the bending pitch, bending shape, crushing of the pipe, etc. Even after the pipe is set, the flange can easily follow when the flange rising portion is bent back, and the pipe and the side plate can be easily fixed. Also, the bending back force of the flange rising portion can be made smaller because a plurality of elongated holes are provided around the pipe insertion hole, and the side plate can be thinned.
