本発明は、偏平多孔冷媒管（以下偏平管と総称する）と
マルゲートフィン（以下フィンと称する）とを有する熱
交換器に関し、特にその製造方法の改良に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger having flat porous refrigerant tubes (hereinafter collectively referred to as flat tubes) and margate fins (hereinafter referred to as fins), and particularly relates to an improvement in the manufacturing method thereof. be.
従来、偏平管とフィンを用いた熱交換器は第１図（ａ）

この偏平管１間の空隙にフィン２を配設する形状となっ
ており、他のタイプの熱交換器に比して、伝熱性能及び
生産性にも優れているため、自動車用空調装置の凝縮器
や蒸発器として多用されている。Conventionally, a heat exchanger using flat tubes and fins is shown in Figure 1 (a).
, as shown in (b), the flat tube 1 is bent in a meandering manner,
The fins 2 are arranged in the gap between the flat tubes 1, and it has superior heat transfer performance and productivity compared to other types of heat exchangers, so it is suitable for automotive air conditioners. It is often used as a condenser or evaporator.

ため、多種類の熱交換器を製造する場合には治具の共通

た。なお、治具にはロー付は治具の他にロー付は治具に
セットする以前に用いる組付は用治具も必要となるため
、ロー付は治具と同様に組付は治具も熱交換器の形状に
より多種の治具が必要となっていた。However, in the heat exchanger of the type shown in Fig. 1, the flat tube 1 is bent into a meandering shape, the fins 2 are inserted, and then the heat exchanger is heated in a furnace. A heat exchanger was obtained by joining the flat tubes 1 together, but in this manufacturing method, the bending accuracy of the flat tubes 1 was a serious problem. That is, when inserting the fin 2 into the gap between the flat tubes 1, if a large clearance is made between the flat tube 1 and the fins 2 in order to facilitate the insertion of the fins 2, brazing will not be performed well, and In order to perform brazing well, if the clearance is made small, the work of inserting the fins 2 will become difficult, and the workability will deteriorate. Even if a certain clearance is maintained and the brazing is performed well, the number of fins 2 inserted into the gaps between the flat tubes 1 is large.
The assembly had a defect that made the work complicated. Furthermore, in the above-mentioned method, it is sometimes necessary to braze the flat tube 1 and the fins 2 using a jig 6 as shown in FIG. If the pressing force is too weak, the brazing will be incomplete, and if the pressing force is too strong, problems such as buckling of the fins 2 will occur. Furthermore, the same jig cannot be used for heat exchangers with special shapes or greatly different sizes, so when manufacturing many types of heat exchangers, it is necessary to use a common jig. It had a defect that made it difficult to convert and required various types of jigs. In addition, in addition to the jig for brazing, a jig is also required for assembly, which is used before setting it on the jig. However, various types of jigs were required depending on the shape of the heat exchanger.
本発明は上述のような製造上の欠陥を除去し、簡易な方
法により熱交換器を得られる製造方法を提供することを
目的とするものである。An object of the present invention is to provide a manufacturing method that eliminates the manufacturing defects described above and allows a heat exchanger to be obtained by a simple method.
以下、本発明による製造方法を″図面を参照しながら説
明する。Hereinafter, the manufacturing method according to the present invention will be explained with reference to the drawings.

ン２よ構成る熱交換器を得ることができる。First, as shown in FIG. 4, a flat porous refrigerant tube 1 in the form of a flat plate before being bent into a meandering shape is prepared. 41 and a plurality of pins 42 protruding from both sides of the base part 41 with a certain gap between them, the fi/2 and the flat tube 1 are arranged between the pins 42, and a flat plate is placed above the pins 42. By locking the holding plate 5 having a shape, the fi/2 on the upper surface of the flat tube 1 is fixed. Brazing work is carried out by placing such a conveying device 4 into a furnace. In this process, the flat tube 1 and the fins 2 are joined by brazing. Furnace brazing involves flat tube 1 to which later fins 2 are joined. By bending the tube in a meandering manner as shown in FIG. 6, a heat exchanger consisting of flat tubes 1 and fins 2 disposed in the gaps between the flat tubes 1 can be obtained.
上述のような製造方法においては、ロー付は治具として
炉中搬送装置だけで、製造することができ、この搬送装
置も熱交換器の最終形状にかかわらず共通化することが
可能となるので、製造が容易で多品種少量生産への対応
も容易に行なえることとなる。In the manufacturing method described above, brazing can be manufactured using only the furnace conveyance device as a jig, and this conveyance device can also be used in common regardless of the final shape of the heat exchanger. It is easy to manufacture and can easily handle high-mix, low-volume production.
また、従来のロー付は炉は、生産される熱交換器の最大
形状に対応させて炉の大きをを決定していたが、本発明
の製造方法にあっては、炉を通過する製品の断面積が常
に一定であるだめ、生産量のみを考慮して最小の炉を設
計することが可能となる。In addition, in conventional brazing, the size of the furnace was determined in accordance with the maximum shape of the heat exchanger to be produced, but in the manufacturing method of the present invention, the size of the furnace is determined according to the maximum shape of the heat exchanger to be produced. Since the cross-sectional area is always constant, it is possible to design the smallest furnace considering only the production volume.
さらに、ロー付は後偏平管を屈曲させる場合、に、屈曲
作業における屈曲寸法精度を必要としないため作業が容
易となる。Furthermore, brazing does not require precision in bending dimensions when bending the rear flat tube, making the work easier.
