悪いという欠点があつた。 However, according to such a configuration, the outer tube 1' has a large diameter, and due to processing, the cross section is not a perfect circle but an ellipse, and the diameter size varies. For this reason, it is necessary to increase the width of the groove 2a' of the end plate 2' so that it can be joined to the end plate no matter which outer tube is used, and accordingly, the amount of glass 3' applied to the groove 2a' must be increased. have to do a lot. As a result, the material cost required for the end plate 2' and the glass 3' increases, the processing is complicated to form the groove 2a' and the rate of processing defects is high, and the heating temperature is increased because a large amount of the glass 3' is used. It is expensive and requires a long heating time, which has the disadvantage of poor productivity.

よりなる接着剤である。 Reference numeral 2 denotes an end plate made of chromium nickel steel with a copper support tube 8 welded to the central hole 7 for firmly supporting the heat collecting tube 4, and a truncated conical portion 2a attached to the truncated conical end 1a at the peripheral edge. is formed. This truncated conical portion 2a has an aperture angle B smaller than the aperture angle A, a lower bottom diameter R 3 is larger than an opening diameter R 1 , and an outer tube 1
It is drawn to be smaller than the diameter R 4 and the upper base diameter R 5 is smaller than the opening diameter R 1 , and radial pleats 9 are press-formed in advance before this drawing. This end plate 2 is made to have a thickness of, for example, 0.2 to 0.3 mm, and by heating and pressurizing it, the folds 9 of the truncated conical portion 2a are configured to have an elongation drawing angle A as shown in FIG. 3B. ing. 3 is the truncated conical end 1
This is an adhesive made of low melting point glass that bonds and secures the truncated conical portion 2a and the truncated conical portion 2a.

接触させて接合固着する。 In the above configuration, the heat collector is manufactured as follows. That is, the adhesive 3 is applied thinly to the inner surface of the truncated conical portion 2a of the end plate 2, and the induction coil 10 is placed on the side of the end plate 2, and the end plate 2 is heated by induction by energizing the induction coil 10. The adhesive 3 is softened by the temperature rise of the end plate 2, and the end 1a of the outer tube 1 is attached to the truncated conical part 2a of the end plate 2.
Press strongly in the direction of the arrow X to stretch the pleats 9 and bring them into surface contact to secure the joint.

ラツキが吸収され良好な接合を得られる。 According to the configuration of the above embodiment, three layers of adhesive can be formed thinly and uniformly by surface contact, and the required adhesive layer can be formed thinly and uniformly.
Since the amount of adhesive can be reduced and the adhesive area is large, the adhesive strength is increased. Moreover, since the groove portion 2a' of the conventional device is not required, the area of the end plate 2 can be reduced, the amount of material forming the end plate can be reduced, and the end plate 2 can be easily processed by press drawing. Furthermore, since the amount of adhesive 3 is small, the heating temperature can be lowered and the heating time can be shortened. Further, even if the machining accuracy of the truncated conical end portion 1a of the outer tube 1 is poor due to the presence of the corrugations 9, the variation in machining accuracy is absorbed by the degree of elongation of the corrugations 9, and a good joint can be obtained.

が大きくなる等多大なる効果を奏する。(c) Effects According to the present invention configured as described above, there is no need for a conventional groove on the periphery of the end plate, which reduces the cost of materials for forming the end plate. Since it is sufficient to form a thin adhesive layer between the bonded surfaces by surface bonding with the truncated conical end of the heat collector, the amount of adhesive can be reduced, and a heat collector with low material costs can be provided.
In addition, the shape of the end plate is simpler and easier to work with than in the past, and it can be bonded with less adhesive, so the heating temperature can be lowered and the heating time can be shortened, resulting in good productivity. Furthermore, the face-to-face contact between the end plate and the outer tube increases the adhesive strength and provides other great effects.
