As shown in (a), a pair of reinforcements 1 and 2 are prepared. For the reinforcements 1 and 2, for example, aluminum or an aluminum alloy is used. An example is a material in which JIS 3003 is used as a core material and JIS 4045 or 4343 is clad on the fin side as a brazing material layer.

Notches 1a and 2a are formed at longitudinal ends of the reinforces 1 and 2, respectively, into which a tube support member 36 for regulating an end surface position of a fin 5 described later enters. By forming the notches 1a, 2a, the tube support member 36 is prevented from colliding with the reinforces 1, 2 when regulating the position of the end face of the fin 5.

Next, as shown in FIG. 1B, after the reinforcements 1 and 2 are arranged at a predetermined interval, a first heat exchanger tube is provided between the reinforcements 1 and 2. A plurality of radiator tubes 3 are arranged at a predetermined pitch. In order to arrange the radiator tubes 3, a tube arrangement device described later is used. For example, aluminum or an aluminum alloy is used for the radiator tube 3. For example, JIS-30
03 as core material and JIS 4045 or J as brazing material layer

Radiator tube 3 and condenser tube 4
Are aligned on a straight line. Next, FIG.
As shown in (c), each fin 5 is compressed by pushing the tube support member 36. At this time, since the notches 1a and 2a are formed at both ends of the reinforces 1 and 2, the tube support member 36 does not come into contact with the reinforces 1 and 2 and the position of the end face of the fin 5 is reduced. Can be regulated. Then, after lowering the comb blade-shaped positioning arrangement member 34 below the set base 30,
The temporarily assembled tube and fin are compressed by the compression mechanism in the tube and fin arrangement direction shown in FIG.

Similarly, the condenser header 6 is positioned by contacting the condenser header positioning member 111, and is clamped by a pair of condenser header clamp members 113. When the radiator header 7 and the condenser header 6 are received from the header temporary holding device 32, the radiator header 7 and the condenser header 6 are mounted on the compressed tube.

Next, a positioning member having a comb blade shape (substantially the same shape as the positioning array member 34) formed in accordance with the pitch between the tubes after compression is mounted on the positioning array member 3 described above.
Then, the tube is lowered in the direction opposite to the direction 4 and each tube is inserted into each slit formed in the positioning member. Then, after lowering the entire tube arrangement device 31, the header mounting device 106 holding the radiator header 7 and the condenser header 6 is advanced,
As shown in FIG. 36, the radiator header 7 and the condenser header 6 are mounted on a temporarily assembled tube.

Next, the baking jig assembling device 33 is operated to put the baking jig 61 from below the set base 30 onto the heat exchanger on which the radiator header 7 and the condenser header 6 are mounted. And assemble it. When the baking jig 61 is assembled, the platen 1
After lowering 9, it is sent along the upper rail 20 to the heat exchanger take-out position. Here, the assembled heat exchanger is removed from the platen 19. Then, the empty platen 19 is lowered onto the lower rail 21 by the platen lowering mechanism 22 and sent to the radiator tube array 10 again.

By sequentially performing the above steps, a heat exchanger in which the radiator and the condenser are integrated is manufactured. In the present embodiment, in order to make the present invention easy to understand,
Although one platen is run on the rail, actually, a plurality of platens are continuously run to improve the productivity of the heat exchanger.

The specific embodiments to which the present invention is applied have been described above. However, the present invention is not limited to the above-described embodiments, and various changes can be made.

In the above-described embodiment, an example has been described in which a heat exchanger in which the first heat exchanger and the second heat exchanger are integrated is manufactured. However, even when a single heat exchanger is manufactured, the present invention can be used. It is needless to say that can be applied. Also,
