[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the fastening structure of the present invention, FIG. 2 is an enlarged view of a main part thereof, and FIG. 3 is a longitudinal sectional view showing a fastening state of the same structure. Generally, the radiator 3 for a vehicle has a larger heat exchange amount than the condenser 6 for a car air conditioner, and therefore has a larger weight and a larger size. Then, the condenser 6 is fastened and fixed to the radiator 3 which is more stable at the time of installation. In this example, the radiator 3 has a pair of radiator tanks 1 arranged in parallel to the direction of gravity, a first core 2 composed of a number of tubes 14 and fins 15 arranged therebetween, and both ends of each tube 14. The part communicates with the radiator tank 1. The radiator tank 1 is composed of a tubular body 1a having a rectangular cross section and an upper lid 1b and a lower lid 1c for closing both upper and lower ends thereof. Then, a tube insertion hole is inserted into one side surface of the tubular body 1a, an end of the tube 14 is inserted therein, and the inserted portion is liquid-tight brazed and fixed. In this example, the tube 14 is formed of a flat tube, and corrugated fins 15 are arranged between the flat tubes, and the contact portions of both are integrally brazed and fixed.

Next, the upper lid 1b and the lower lid 1c are aligned with the outer periphery of the cross section of the tubular body 1a, are fitted to the upper and lower ends of the tubular body 1a, and the fitting portions are integrally brazed and fixed. Become. An embedded nut made of a cap nut is liquid-tightly fixed to the front side of the tubular body 1a. As shown in FIGS. 2 and 3, the lower lid 1c is integrally formed with a holding portion 7 protruding in a hook shape at the upper edge on the front side. In this drawing, a cooling water inlet / outlet pipe, a water supply cap and the like are omitted from the radiator 3. Next, the condenser 6 has a pair of headers 4 spaced apart left and right similarly to the radiator 3, and the second core 5 including a large number of tubes 14 and fins 15 is arranged between them. Both ends of the tube 14 arranged in the horizontal direction are connected to the header 4. At the upper end of each header 4, one end of a bolt fitting 11 is brazed and fixed. At the same time, one end of a mounting bracket 9 is fixed to the lower end of the header 4 by brazing. A rubber buffer 10 is fitted and fixed to the tip of the mounting bracket 9. The outer periphery of the rubber cushion 10 is aligned with the holding portion 7 of the radiator 3.

[0008] The radiator 3 and the capacitor 6 thus constructed are assembled as follows. First, the mounting bracket 9 of the capacitor 6 is fitted to the holding portion 7 of the radiator 3 via the rubber buffer 10. Next, the bolt hole of the bolt mounting bracket 11 and the bolt screw portion 8 are aligned, and a fastening bolt 12 is screwed and fastened to them. In order to attach the rubber buffer 10 to the mounting bracket 9, a recess slightly smaller than the cross section of the mounting bracket 9 is formed on one side of the rubber buffer 10 in advance, and the mounting bracket 9 is formed in the recess. It is enough to press-fit the tip. Further, instead of attaching the rubber buffer 10 to the mounting bracket 9, the rubber buffer 10 is attached to the holding portion 7 by bonding or press-fitting, and a slit is formed on the upper surface thereof so as to match the cross section of the mounting bracket 9, The fitting 9 may be press-fitted from above.

[Functions and effects of the invention]

 According to the first aspect of the present invention, the lower lid 1c of the radiator tank 1 is provided with the holding portion 7, and the mounting metal 9 of the capacitor 6 is fitted to the holding portion 7 via the rubber buffer 10. Thus, the lower portion of the condenser 6 is supported by the radiator tank 1. Therefore, it is possible to provide a fastening structure that is easy to manufacture and reduces the number of parts, and easily connects the radiator tank 1 and the capacitor 6. According to the second aspect of the present invention, the lower lid 1c is formed in a cup shape, and the holding portion 7 is formed to project from the upper edge thereof, so that the radiator 3 constituting the radiator tank 1 is formed. The connection between the radiator tank 1 and the lower lid 1c can be more easily performed, and the liquid-tight structure of the radiator tank 1 can be reliably performed, and a fastening structure with a small number of parts can be provided. Further, since the present fastening structure has a structure in which the capacitor 6 is fitted to the holding portion 7 of the lower lid 1c via the rubber buffer 10, it absorbs vibration and thermal expansion during use, and has high reliability. A fastening structure can be provided.
