DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator for an automobile in which a shroud having a fan and a radiator are assembled.

[0002]

2. Description of the Related Art As a conventional heat radiating device for an automobile of this type, there is, for example, one shown in FIG.
And Japanese Utility Model Laid-Open Publication No. 2-31342). Incidentally, FIG. 12, Hidarihasu above indicates the vehicle front F _r.

[0003] This automotive radiator has a structure in which a shroud 1 and a radiator 3 are assembled. The shroud 1 is integrally formed as a whole, and a pair of motor fans 5 is attached as a fan. In addition, a shroud upper bracket 7 is provided at two places above the shroud 1, and a shroud assembling piece 9 is provided at two places below. The radiator 3 is provided with two radiator upper brackets 11 at the upper rear portion on the rear side in the vehicle longitudinal direction. In addition, two shroud mounting brackets 13 are provided at the lower part of the rear surface. Each of the shroud mounting brackets 13 has a fitting hole 15.

Then, the shroud assembling piece 9 is inserted into the fitting hole 15 of the shroud mounting bracket 13, and the upper shroud bracket 7 is connected to the radiator upper bracket 11.
Are fastened by bolts 17. Thus, the shroud 1 is configured to be securely attached to the radiator 3 side.

The radiator 3 is provided with radiator lower mounting pins 19 at two locations and the radiator 3 is provided with radiator upper mounting pins 21 at two locations. The radiator lower mounting pin 19 is supported on the first cross member side of the vehicle body (not shown) via an insulator (not shown) or the like. Referring to FIG. 15, the radiator upper mounting pin 21 is provided with a radiator core support upper 29.
Is supported via an insulator 32 on a mounting stay 31 supported by the mounting bracket 31. In FIG. 12, 23 is a radiator hose.

[0006]

However, in the case of the above-described structure, when the shroud 1 is removed from the radiator 3 side for maintenance of the motor fan 5 and the like, the removal operation becomes extremely complicated. there were. That is, on both sides of the radiator 3 in the vehicle width direction, FIG.
Since the front side member 25 exists as shown in FIG. 3, when the shroud 1 is removed, the shroud 1 must be pulled upward. But shroud 1
Since the radiator hose 23 exists above the radiator 3, the radiator hose 23 must be removed from the radiator 3 every time the shroud 1 is removed, and the operation becomes extremely complicated.

In order to prevent interference with the radiator hose 23, the shroud 1 may be rotated as shown by a two-dot chain line in FIG. 13, but the lower corner portion 27 (hatched portion) of the shroud 1 is located at the front. Since it interfered with the side member 25, it could not be simply removed.

On the other hand, if the lower corner 27 of the shroud 1 is eliminated as shown in FIG. 14, rotation as shown by a two-dot chain line in FIG. 13 is possible, but there is a possibility that the heat radiation performance of the radiator 3 is adversely affected. There is. That is, if the lower corner portion of the shroud 1 is eliminated as shown in FIG.
This is because the radiator 13 cannot take in the cooling air at that portion and cannot exchange heat. Also, a heat return path is created as shown by arrows A and B in FIG.

On the other hand, in order to remove the shroud 1 without losing the lower corner 27 of the shroud 1 and without removing the radiator hose 23, the connection position of the radiator hose 23 must be changed as shown in FIG. It is conceivable to change from the position of (a) to the position of FIG. However, when the connection position of the radiator hose 23 is changed in this manner, it is necessary to increase the height of the mounting stay 31 on the radiator core support upper 29 side that supports the radiator upper mounting pin 21, and the height of the vehicle body hood is accordingly reduced. Raises the problem of having to take measures such as raising

The surface 9 is oriented in the vehicle longitudinal direction. On the lower rear edge side of the side portion 39, a side contact portion 53 is provided. The side abutment portion 53 is provided with two upper and lower clips 55 constituting a separation engagement portion. As shown in FIG. 2 and FIG. 4, on the upper side of the side portion 39, clip engaging portions 57 forming an engaging portion on the surface facing the main portion 33 are provided at two upper and lower positions. This clip locking portion 57
Is constituted by a pair of opposed insertion pieces 57a. An engagement claw 59 is protruded from the uppermost portion of the side portion 39.

On the other hand, as shown in FIGS.
A clip 61 forming an engaging portion is formed at two upper and lower portions on the side portion of. The clip 61 has a T-shaped cross section, and has a shape into which the insertion piece 57a can be inserted from above. The engaging wall 61a of the clip 61 has a shape in which an upper portion is spread outward as shown in FIGS. Therefore, the insertion piece 57a is easily inserted and guided. A locking hole 63 for locking the engaging claw 59 is formed above the side of the main body 33.

At the time of assembly, first, a side portion 39 is attached to a side portion of the main body portion 33 in FIG. In this mounting, the side portion 39 is opposed to the side portion of the main body portion 33, and the insertion portion 57a of the clip locking portion 57 is inserted and locked into the clip 61 as shown in FIG. When the engagement between the clip 61 and the clip engaging portion 57 is complete, the engaging claw 59 is fitted into the engaging hole 63. If it is incomplete, it can be confirmed that the engagement claw 59 is incomplete because it does not fit into the locking hole 63. Further, when the engaging claw 59 is fitted into the locking hole 63, the engagement between the clip locking portion 57 and the clip 61 can be locked, so that the side portion 39 can be securely attached to the main portion 33. It can be.

Next, the main body 37 is attached to the lower corner. This attachment is made by the clip 5 of the side abutment 53.

The dividing part 35 is connected to the main part 33 to
The shroud 1 integrated as described above is assembled on the radiator 3 side. After the radiator 3 and the shroud 1 are assembled on the vehicle body side, if it becomes necessary to remove the shroud 1 for maintenance of the motor fan 5 or the like, the split portion 35 is first removed and the rear main body portion 33 is removed. . The detachment of the dividing part 35 can be performed by reversing the procedure of attaching the main body part 37 and the side part 39 described with reference to FIG. When the split part 35 is removed, the shroud 1 becomes the main part 33 in which the lower corner part 27 is eliminated, and FIG.
The rotation removal described by the two-dot chain line becomes possible. Accordingly, the main body 33 can be removed without interfering with the front side member on the vehicle body side, and at that time, the radiator hose 23 shown in FIG. 1 does not need to be removed. Therefore, the shroud 1 can be removed very easily and without difficulty. In addition, it is not necessary to provide a special detachment space by such detachment, and the structure becomes extremely advantageous in terms of space in an engine room where a large number of parts are densely packed. Further, since there is no need to change the mounting position of the radiator hose 23, there is no inconvenience such as an increase in the height of the hood. Further, after the shroud 1 is assembled, the lower corner 27 can be covered by the divided portion 35, so that the cooling air can be sucked in the lower corner 27 of the radiator 3 and the heat does not blow back, so that the heat radiation performance is sufficiently improved. Can be maintained.
