A heat exchanger including a core portion 5 combined with the heat exchanger is used. When such a heat exchanger is used as a radiator, cooling water flows from the upper tank 1 to the lower tank 2 through a large number of flat tubes 3, 3. And, in this way, a large number of flat tubes 3, 3
The temperature of the cooling water is lowered by causing heat exchange between the cooling water flowing inside and the air flowing through the core portion 5 in the front-back direction of the drawing.

Is to efficiently perform such heat exchange between cooling water and air, and is configured as shown in FIGS. That is, the corrugated fin 4 is made of aluminum, copper,
By forming a strip-shaped metal plate made of brass or the like into a zigzag shape, flat portions 4a and 4a having louvers 4b and 4b and curved portions 4c and 4d having different bending directions are alternately continuous. The air that has flowed in between the flat portions 4a, 4a of the corrugated fin 4 as shown by an arrow a in FIG.
As shown by the arrow b in the figure, it flows meandering between the louvers 4b, 4b. The corrugated fins 4 and 4 have flat portions 4a and 4a.
The outer peripheral surface portions of the curved portions 4c and 4d formed on both sides of the flat tubes 3 and 3 are brazed to the side surfaces of the flat tubes 3 and 3. Therefore, the heat of the cooling water flowing through the flat tubes 3 and 3 is transferred to the corrugated fins 4 and 4. Therefore, as described above, the cooling air is efficiently radiated by the air flowing between the louvers 4b, 4b.

That is, the blade plate 8 that constitutes the molding blade
Conventionally, it has teeth 6 as shown in FIG. This tooth 6
The top portion 6a has a curved convex surface, the bottom portion 6b has a curved concave surface, and a louver cutting and raising blade 6c is formed on the hypotenuse portion that connects both portions 6a and 6b. As shown in FIG. 13, a plurality of blade plates 8 having such teeth 6 formed on the outer circumference are superposed on each other to form a pair of gear-shaped forming blades 7a and 7b.
Then, the two molding blades 7a and 7b are combined so as to mesh with each other as shown in FIG. When the corrugated fin 4 is formed, the strip-shaped metal plate 9 is fed between the forming blades 7a and 7b while rotating the forming blades 7a and 7b in opposite directions. The teeth 6, 6 on the outer circumference of each of the plurality of blade plates 8, 8 constituting the forming blades 7a, 7b are the thirteenth to fourteenth teeth.
Since they are meshed as shown in the figure, the strip-shaped metal plate 9 fed between the molding blades 7a and 7b meshed with each other as described above.
Is a louver on the flat part with a corrugated shape that matches the outer shape of the teeth 6, 6.
Fin element 10 is obtained by cutting and raising 4b and 4b. This fin element 10
Is compressed in the lengthwise direction to narrow the gap between the flat portions on which the louvers 4b and 4b are formed to complete the corrugated fin 4.
（発明が解決しようとする課題） ところが、上述の様な従来のルーバ付コルゲートフィン

６との間に働く付着力が大きくなる。That is, conventionally, as shown in FIG. 13, the louvers 4b and 4b having an inclination angle of about 15 to 30 degrees with respect to the flat portion 4a (in the case of fins made of aluminum) were formed in one movement. When the louvers 4b and 4b having such a relatively small inclination angle are formed between the pair of forming blades 7a and 7b meshed with each other in a gear shape, the louvers 4b and 4b are just formed. Elementary

歪んだり、或は刃6cの寿命を短くしたりする。Furthermore, after molding the fin element 10, the blades 6c of the teeth 6 of each molding tooth and the louvers 4b tend to adhere to each other. As a result, the fin element 10 immediately after molding has one molding blade 7a (or
7b) while being attached to the outer peripheral surface of the molding blade 7a (or
7b) is sent to the rear in the rotational direction to distort the shape of the fin element 10 or shorten the life of the blade 6c.

It will not be sent. That is, since the inclination angle of the louver cut and raised in the flat portion in the first step is larger than the inclination angle of the louver of the corrugated fin after completion, the adhesive force between this louver and the outer peripheral surface of the molding blade is small, The louver and the outer peripheral surface of the molding tool are easily separated. Therefore, in the first step, the strip-shaped metal plate on which the louver is formed is not sent to the rear in the rotational direction of the forming blade.

The tilt angle of the louvered corrugated fins after completion will not be excessive.

上記帯状金属板９に、第一工程の加工が施される。(Embodiment) FIGS. 1 to 7 show an embodiment of the present invention. When manufacturing the louvered corrugated fin by carrying out the manufacturing method of the present invention, as shown in FIG. 1, the strip-shaped metal plate 9 pulled out from the uncoiler 11 is wound around the tension roll 12 for imparting tension, and further, A pair of forming blades 14a, 14b which pass between the pair of upper and lower guide rolls 13, and mesh with each other in a gear shape.
Send in between. The band-shaped metal plate 9 is processed in the first step between the pair of forming blades 14a and 14b.

However, in the case of the molding knives 14a and 14b used in the practice of the present invention, as shown in FIG. 2 which is an enlarged AA sectional view of FIG. Set the blade tilt angle θ 1 to the completed louver tilt angle θ 2
It is larger (θ 1 > θ 2 ) than (Fig. 5). For example, when the corrugated fins are made of aluminum, the louvers 4b, 4b after completion have an inclination angle θ 2 of about 15 to 30 degrees, while the louvers 4b 'by the forming blades 14a, 14b, The cutting-and-raising angle θ 1 of 4b ′ is about 30 to 45 degrees.

有するルーバ4b′、4b′が形成される。The strip-shaped metal plate 9 pulled out from the uncoiler 11 as described above has a large number of blades having a large inclination angle θ 1 on its outer peripheral surface and passes between a pair of forming blades 14a, 14b which mesh with each other. By doing so, the processing of the first step is performed and the whole is formed in a zigzag. Along with this, the louvers 4b of the completed corrugated fins are attached to each flat portion as shown in FIG.
Louvers 4b ', 4b' having an inclination angle θ 1 larger than the inclination angle θ 2 (FIG. 5) of 4b are formed.

（14b）の回転方向後方にまで送られる事はない。Since the inclination angle θ 1 of the louvers 4b ′, 4b ′ formed in this first step is sufficiently large, the adhesion between the outer peripheral surfaces of the molding blades 14a, 14b and the louvers 4b ′, 4b ′ is weak, The outer peripheral surfaces of the molding blades 14a, 14b and the fin elements 16 of the first stage in which the louvers 4b ', 4b' are cut and raised are smoothly separated.
Therefore, with the fin element 16 attached to the outer peripheral surface of any of the molding blades 14a (or 14b), the molding blade 14a
It will not be sent backwards in the direction of rotation of (14b).

The 6 is then fed between the pair of upper and lower shaping rolls 15a and 15b. The shapes and configurations of the shaping rolls 15a and 15b are similar to those of the shaping blades 14a and 14b described above. However, since each of the forming rolls 15a and 15b does not cut and raise the louver, no blade is provided.

As shown in FIG. 3, which is an enlarged BB cross-sectional view of FIG. 1, the inclination angle θ 2 of the louvers 4b, 4b in the completed corrugated fin is made to coincide. Furthermore, in the example shown,
By means such as holding a spacer (not shown) between the plate sides 17, 17 composing each shaping roll 15a, 15b,
The gaps 18 and 18 are formed so that the edges of the louvers 4b and 4b do not contact the side surfaces of the adjacent plate pieces 17.

This is only for reducing the inclination angle of 4b ', and it is not always necessary to stack a plurality of plate pieces 17, 17 as shown in FIG. For example, as shown in FIG. 6, a recess 20 is formed on the inclined surface of the tooth 19 formed on the outer periphery of the shaping roll,
By pressing the louvers 4b, 4b between the recesses 20 as shown in FIG. 7, the inclination angles of the louvers 4b, 4b can be adjusted to the completed inclination angle θ 2 .

It will not adhere to any of the blades. As a result, not only the shape of the louvered corrugated fin after completion is not distorted, but also the life of the molding blade is prevented from being shortened, and a good quality louvered corrugated fin can be provided at low cost.
