樹脂製のものが採用されるようになつてきた。
Recently, radiator tanks have been made of resin instead of the conventional ones made of brass (including aluminum), mainly from the viewpoints of ease of manufacture, weight reduction, and cost reduction. I'm getting old.
ところで、ラジエータ用タンク（アツパ・タン

加えて、成形型の構造が複雑となる上、中子の抜
き孔ｄが形成されるので、これを閉鎖する蓋ｅを
溶着する作業を必要とし作業性を低下させる。 By the way, radiator tanks (upper tanks and lower tanks) are equipped with water conduit pipes such as inlet pipes, outlet pipes, and fillets, so they are not made of resin as described above. Usually, these water conduit pipes a are designed to be integrally formed with the tank main body b, as illustrated in FIG. 1, to take advantage of the moldability of resin. However, in the case of such an integrally molded type, especially when the water pipe a is subjected to a bending moment due to vibration or the like like a filler neck, the area near the root c of the water pipe a connected to the main body b of the tank is There is a problem that cracks occur in the metal, causing functional deterioration.
In addition, the structure of the mold becomes complicated, and since a core punch hole d is formed, it is necessary to weld a lid e to close the hole d, which reduces work efficiency.
このようなことから、従来の多くの樹脂タンク

る。 For this reason, many conventional resin tanks have a tank main body b' and a water conduit pipe, as shown in Figure 2.
The structure is such that a' is molded separately and then integrally joined. To explain this joint part in detail, joint flanges f and g are formed at each joint end of the tank main body b' and water conduit a', and either one of the joint flanges f and g (in the case shown, the joint flange An O-ring groove h is formed in the end face of g), and the tank main body b' and water conduit a' are connected to the O-ring groove h.
After inserting the O-ring i into the ring groove h, both the joining flanges f and g are joined and connected by fastening them with a plurality of bolts j and nuts k.
ところで、このような結合タイプのものにあつ

随分と軽減することが可能となるが、その反面、
次のような別の問題が生じ、やはり実用上芳しい
ものではなかつた。
By the way, in the case of such a joint type, it is possible to considerably reduce the problems of the above-mentioned integrally molded type, but on the other hand,
Another problem occurred, as described below, and it was not practical.

弛み、接合不良を来して水密性を損なう。 That is, since the tank main body b' and the water conduit a' are connected by a plurality of bolts j, not only is the assembly work time-consuming, but also the connection flange f depends on the tightening force of the bolts j. , g may be bent and the watertightness may be impaired, or the joint flanges f and g may be poorly connected and the watertightness may be impaired.
It is very difficult to tighten the bolts, and even if they are connected in a watertight state by O-rings i by adjusting the temporary bolts j, the bolts j will loosen when subjected to vibration, resulting in poor joints and watertightness. spoil.

As described above, according to the present invention, in a heat exchanger with a resin tank, in which the main body of the tank and the water conduit pipe installed on the outer wall are separately molded and then integrally joined, A rectangular flange having approximately semicircular longitudinal grooves on both end faces is formed on the water pipe, and a U-shaped protrusion is formed on the outer wall of the main body of the tank to join with both end faces and the lower end face of the flange of the water pipe. A flange fitting part is formed of a wall, and a flange fitting part is formed with approximately semicircular vertical grooves on the inner wall surfaces on both sides thereof,
The water conveyance pipe is constructed by fitting the flange into the flange fitting part, and then inserting the knock pin into the knock pin insertion part formed by the matching flange and the vertical groove of the flange fitting part. Since it is integrally connected to the main body, there is no need to use bolts to connect it, and joint failures due to bending of the joint flange when tightening bolts are avoided, making it easy to connect the tank main body and water pipe. It is certain. In addition, since the shearing force of the knock pin is extremely small because the load is applied to the pull-out load of the pipe by the size and length of the knock pin, this is advantageous in terms of strength. Therefore, it is possible to ensure high coupling reliability. Furthermore, since the contact surface between the water pipe and the main body of the tank is large, the load applied to the joints is reduced, and the problem of cracks occurring at each joint is eliminated.
