面３とが極めて馴染み易い利点がある。 In this embodiment, the oil cooler main body 5 made of a double pipe is closed at both ends as shown in FIG. 5, and short pipes 6 are brazed at both ends in the longitudinal direction as shown in FIG. Fixed. An inner fin 12 is provided inside the double pipe as shown in FIG. Next, the hollow bolt member 4 fitted onto the outer periphery of this short tube 6 is constructed as shown in FIGS. 4 and 1. That is, a collar portion 1 is provided at the rear end, and the outer periphery thereof is formed into a hexagonal shape. At the same time, an annular groove is formed on the tank contact side side of the collar 1, and an O-ring 13 is formed therein.
is fitted. Further, a threaded portion 2 is threaded on the outer periphery of this hollow bolt-like member 4. Along with that,
A widening surface 3 is formed at its tip. Then,
This hollow bolt-like member 4 is inserted into the short tube 6, and the first
As shown in the figure, these are inserted into the opening of the tank 9.
Then, the hollow bolt member 4 and the tank 9 are fluid-tightly fastened together with the washer 11 and the nut 10 via the O-ring 13. Next, as shown in FIG. 1, the connecting pipe 8 has a nut-shaped rear end and a stepped interior. A pressure contact surface 7 is formed on this stepped portion, and this pressure contact surface 7 is formed to align with the expansion surface 3 of the hollow bolt-like member 4. Note that this connecting pipe 8 has a short pipe fixed to it via a brazed portion 14a, and is formed into a cylindrical shape as a whole. By screwing this connecting tube 8 onto the tip of the hollow bolt member 4, the pressure contact surface 7 presses the tip of the short tube 6, and the pressing force causes the tip of the short tube 6 to move as shown in FIG. It is pressed against the expanded surface 3 as shown in FIG. Thereby, the tip of the short tube 6 is deformed as if it were flared, and the connecting tube 8, the short tube 6, and the hollow bolt member 4 are fixed liquid-tightly. Note that the hollow bolt member 4
The shape of the tip may be formed as shown in FIG. Alternatively, the flaring of the tip of the short tube 6 may be performed in advance using an appropriate jig, without using the connecting tube 8. However, when flaring is performed using the connecting pipe 8, there is an advantage that the pressure contact surface 7, the tip of the short pipe 6, and the widening surface 3 are very easy to fit together.

４に外力が加わるから、該ろう付け部１４に亀裂
が生じ、漏れの原因となつていたが、本考案では
このようなろう付け部１４の亀裂を防止きる。 Since the brazing part 14 is located at the contact part between the rear end of the short pipe 6 and the oil cooler body 5, and there is no need to braze the oil cooler body 5 and the flange part 1, the brazing structure is extremely simplified. Brazing reliability and productivity are greatly improved. Furthermore, even if an external force is applied to the connecting pipe 8, this will not cause cracks in the brazed portion 14. That is, since the hollow bolt member 4 and the short pipe 6 are constructed separately and are not brazed, the external force applied to the connecting pipe 8 is supported by the flange 1 of the hollow bolt member 4 and the tank 9, and the brazing force is applied to the connecting pipe 8. It does not affect the attachment part 14. Therefore, a highly reliable mounting structure can be provided. Incidentally, in the conventional mounting structure, when an external force is applied to the connecting pipe 8, the external force is transmitted through the flange 1 to the brazed part 1 between the flange 1 and the oil cooler main body 5.
4, cracks occur in the brazed portion 14, causing leakage, but with the present invention, such cracks in the brazed portion 14 can be prevented.
