Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile heat exchange device, and more particularly to a fan-shroud automobile radiator and a mounting structure for an automobile body.

In the conventional radiator 1 with a resin tank and shroud 2, a bolt 3 is fastened to a nut portion 3a formed integrally with the resin tank, as shown in FIGS. It was fixed to the vehicle side via a bushing, etc.). That is, the upper tank 5 part is bolted, and the lower tank 6 part is fastened with bolts.
The part was attached by inserting and fitting the tank boss part 7.

As described above, the conventional heat exchanger has a structure in which a mounting part for fixing the shroud is provided on the heat exchanger body and is fastened with bolts. For this reason, (1) the structure of the heat exchanger body is complicated, (2) shroud fixing parts are required, and (3) the heat exchanger body must be assembled to the vehicle after the electric fan is assembled to the heat exchanger. There is a problem that the number of man-hours increases.

In view of the above points, the object of the present invention is to integrate the fan shroud fixing with the vehicle mounting of the radiator. Hereinafter, one embodiment of the present invention will be described based on the drawings. 3 and 4, reference numeral 1 denotes an upper tank made of resin reinforced with glass fibers, and this tank 1 is provided with an introduction pipe 1a that leads cooling water from an automobile engine (not shown) and a water inlet 1b. ing. The cooling water introduced into the upper tank 1 is distributed and supplied to the core section 21, and is cooled by the cooling air blown from the fan 22 when passing through the core section 21. After that, the cooling water is collected in the lower tank 23, and then the outlet 23a
It is then circulated back to the engine.

The fan shroud 2 is for properly guiding the cooling air sent from the fan 22 to the core part 21.
It is arranged so as to cover the outer periphery of the fan 22. Also,
A motor 24 for driving the fan 22 is fixedly held by this fan shroud. This fan shroud 2 is formed by press shaping an iron plate, and fixtures 8 and 9 are welded to the fan shroud 2.

And, this fan shroud 2 has a mounting fixture 8,
It is engaged with the upper tank 1 and the lower tank 23 through the terminals 9, and is attached to the vehicle body in that state.

Next, a process for attaching the fan shroud 2 and the radiator 20 to the automobile bodies 12 and 13 will be explained.

First, as shown in Figures 4 and 5, the lower fixture 9
The mounting protrusion 7 integrally molded on the lower tank 23 is inserted into the mounting hole 9a, and then the rubber bushing 4 is fitted into the mounting protrusion 7.

On the other hand, the upper mounting fixture 8 also has its mounting hole 8a aligned with the mounting hole 10a of the mounting flange 10 integrally formed on the upper tank 1. Then, in this state, as shown in FIG. 6, the rubber bushing 4 is inserted into the mounting holes 8a, 10a using its own elasticity.
Therefore, in this state, the rubber bushing 4
The fan shroud 2 is temporarily fixed to the radiator 20. Then, in this state, the mounting protrusion 7 of the lower tank 23 is inserted into the holding hole 11 of the vehicle body 13 together with the rubber bush 4 to position and hold the radiator 20 below. Next, the mounting flange 10 of the upper tank 1 and the mounting hole 10 of the upper fitting 8
a, 8a to match the mounting hole 12a of the vehicle body 12,
It is fixed via the collar 25 with bolts 26 and nuts 27 that form fixing devices. Particularly, according to this example, the radiator 20 is positioned by the fitting between the mounting projection 7 and the holding hole 11 as described above, and the mounting projection 7 acts as a fixture.
a, 8a, and 12a can be easily aligned.

Further, in this example, rubber bushings 4 are interposed between the vehicle bodies 12 and 13 and the radiator 20 both above and below, so that the bushes 4 prevent the vehicle body from moving.
2 and 13 are prevented from being directly transmitted to the radiator 20. Therefore, the radiator 20 of this example has excellent vibration resistance.

In the above example, the fan shroud 2 is held against the radiator 2 only by the holding force of the rubber bush 4.
0, but if it seems that the connection strength is insufficient with only this rubber bushing 4, other temporary fixing means may be added. 7 to 9 show this embodiment, in which a locking hook 8b is integrally molded on the upper fitting 8, and the upper tank 1
An engagement groove 10b is formed in the mounting flange 10 to engage the locking hook 8b. and,
As shown in FIG. 7, when aligning the mounting holes 8a and 10a, the locking hook 8b is engaged with the engagement groove 10b, and in this state, the rubber bushing 4 is inserted into the mounting hole 8.
a, insert into 10a. In this way, the fan shroud 2 is also fixed by the locking hook 8b, so that temporary fixing can be carried out reliably.

Furthermore, although a resin tank radiator is shown in the above-described embodiment, the present invention can of course be applied to a radiator made of a metal tank. However, in the case of a metal tank, unlike the above-mentioned resin tank, the mounting flange 10 and the mounting protrusion 7 forming a fixture cannot be integrally molded on the tanks 1 and 22. In this case, as shown in FIGS. 10 and 11, iron plate brackets 26 and 27 are fixed to the side surfaces of the radiator 20 by welding or the like.
Match the mounting holes of fixtures 8 and 9 with the mounting holes of 7,
It should be attached to the vehicle body using fixing tools such as bolts.

As explained above, in the present invention, the fan shroud and the radiator are simultaneously fixed to the vehicle body using one fixture, which has the excellent effect of reducing the number of installation steps and making the installation easier.

Further, in the present invention, since the fan shroud and the radiator are fixed to the car body through the elastic material, vibrations from the car are absorbed by the elastic material and are prevented from being directly transmitted to the fan shroud and the radiator. Therefore, failures due to vibration of the fan shroud and radiator can be prevented.
