The cross section is L-shaped so as to avoid the condenser 200 side.

At the opening end of the cylindrical portion 2 on the side opposite to the radiator 100, a flared portion 13 is formed integrally and continuously with the cylindrical portion 2. The flared portion 13 is larger toward the end portion between the inner peripheral surfaces thereof, and has a smaller thickness than other portions and has flexibility. When the radiator 100 and the condenser 200 are installed in the engine room of the vehicle, the mouth opening 13 is pressed against a radiator upper support (not shown) of the vehicle body. On the left side and the right side of the cylindrical portion 2, back wall portions 14 and 15 covering the back surfaces of the inlet header tank 204 and the outlet header tank 205 of the condenser 200 projecting from the heat exchanger 110 of the radiator 100 are provided.

Function as

By tightening the bolt 7, the side plate 212 of the upper bracket 202, the upper mounting wall 3 of the mounting shroud 1, and the mounted portion 106 of the upper tank 101 are tightened together. Further, by tightening the bolt 9, the side plate 21 of the lower bracket 203 is tightened.
4 and the lower mounting wall 4 of the mounting shroud 1 and the mounted portion 109 of the lower tank 102 are fastened together. Thus, the condenser 200 and the mounting shroud 1 are connected to the bolt 7,
9 enables the bolts to be fastened together to the radiator 100, so that bolts required for fixing to each radiator 100 are not required. Therefore, the number of fasteners such as bolts can be reduced, so that the work of fastening the condenser 200 to the radiator 100 can be greatly simplified.

After performing the above mounting work,
A structure (module) in which the condenser 200 and the radiator 100 are integrated is fixed to a front side of an engine room of an automobile by a conventionally known method. In this case, the flared portion 13 formed in the cylindrical portion 2 of the mounting shroud 1 is a partition (not shown) including a radiator support, a radiator upper support, a front cross member, and the like in an engine room. It is fixed in a state where it is pressed. The upper mounting wall 3 and the lower mounting wall 4 of the mounting shroud 1 are connected to the heat exchanging section 11 of the radiator 100.
0, the size of the heat exchange unit 110 of the radiator 100 is equal to or
The condenser 200 having the heat exchange unit 201 having a size larger than that of the radiator 100 can be attached to the radiator 100.

The operation of the mounting shroud 1 according to the first embodiment will be briefly described with reference to FIGS. Cooling air introduced into the engine room of the automobile by a cooling fan (not shown) or the like is guided to the cylindrical portion 2 of the mounting shroud 1 and passes through the heat exchange portion 201 of the condenser 200. At this time, the cooling air exchanges heat with the gas refrigerant flowing through the plurality of tubes 206 of the condenser 200 and is heated.
All the cooling air heated by the condenser 200 is guided to the tubular portion 2 of the mounting shroud 1, the opposing pieces 11, 12 and the back walls 14, 15, and passes through the heat exchange section 110 of the radiator 100. I do. At this time, heat exchange is performed with the cooling water flowing through the plurality of tubes, and the cooling air is further heated to become heated air, which is blown to the rear side of the heat exchange unit 110.

Note that the heated air blown out of the radiator 100 passes through the side of the radiator 100 and tries to turn around again in front of the radiator 100. However, the cylindrical portion 2 of the mounting shroud 1 causes the heated air of the radiator 100 to be turned off. Prevents heated air from flowing forward. Further, the rear side of the radiator 100 and the front side of the condenser 200 are completely shut off by a partition formed of a radiator support, a radiator upper support, a front clone member, and the like, and the cylindrical portion 2 of the mounting shroud 1. This prevents the heated air blown out of the condenser 200 from being introduced again to the front side of the condenser 200.

FIG. 8 shows a second embodiment of the present invention and is a view schematically showing a state in which a condenser is mounted on a vehicle body, as viewed from the side. The condenser 200 is mounted in the engine room 301 of the vehicle body, and the shroud 1 and the radiator 1
It is arranged with 00. The mounting shroud 1 has a flared portion 13 only on the upper side of the tubular portion 2, and the tubular portion 2 extends to the side opposite to the radiator 100 on the lower side, left and right sides of the tubular portion 2. It has a flattened shape.
The flared portion 13 on the upper side of the cylindrical portion 2 is in contact with the radiator upper support 302. A projecting wall 19 extending in a direction substantially perpendicular to the tubular portion 2 is formed on an outer peripheral surface of a lower side portion of the tubular portion 2, and the projecting wall 19 is arranged facing the front cross member 303 with a small gap therebetween. Have been. Here, 304 is a hood cover for covering the engine room 301, 305 is a front grill for introducing cooling air into the engine room 301,
Reference numeral 306 denotes an automobile bumper.

FIGS. 9 to 11 show a third embodiment of the present invention, and show a structure in which a condenser and a radiator are integrated. In this third embodiment, the mounting shroud 1
The upper mounting wall 3 has two insertion holes 21 for the bolts 20 and two screw holes 23 for the bolts 22. A bolt 2 is provided on the side opposite to the radiator 100 of the insertion hole 21.
A recess 24 for accommodating a zero head is formed. In addition, an outer peripheral surface of the lower mounting wall portion 4 is fitted into an engaging recess (not shown) formed in the lower tank 102 of the radiator 100 via an elastic body (not shown) such as a bush. An engagement projection (not shown) is formed. Note that 25
Is a metal insert nut having a screw hole 23 formed in the inner periphery, and is fitted on the front side of the upper mounting wall 3.

An example of a procedure for attaching the condenser 200 of the third embodiment to the radiator 100 will be described with reference to FIGS. First, the engaging projection of the lower mounting wall portion 4 is fitted into the engaging recess of the lower tank 102 of the radiator 100 while tilting the mounting shroud 1 slightly forward. Then, the upper mounting wall portion 3 of the mounting shroud 1 is attached to the mounting portion 1 formed on the upper tank 101 of the radiator 100.
10, the upper mounting wall 3 of the mounting shroud 1 and the mounted portion 106 of the upper tank 101 are fixed by tightening the bolt 20, and the mounting shroud 1 is attached to the radiator 100, as shown in FIG. Attach.

Next, the upper bracket 2 of the condenser 200
02 is pressed against the upper mounting wall 3. At this time, since the head of the bolt 20 is accommodated in the recess 24, the upper bracket 202 abuts on the upper mounting wall without being disturbed by the head of the bolt 20. Then, as shown in FIG. 11, the upper mounting wall 3 of the mounting shroud 1 and the upper bracket 20 are tightened by tightening the bolts 22.
The condenser 200 is attached to the shroud 1 with the second side plate 212 fixed. By such a simple mounting operation, the condenser 200 is mounted on the radiator 100 via the mounting shroud 1.

[Modification] In this embodiment, the mounting wall of the mounting shroud is mounted on the radiator tank.
The mounting wall may be attached to a part fixed to the vehicle body,
The mounting wall may be directly mounted on the vehicle body. In this embodiment, the tubular portion of the mounting shroud and the mounting wall portion are formed integrally and continuously, but the cylindrical portion and the mounting wall portion may be formed separately. For example, the tubular portion may be made of resin and the mounting wall may be made of metal. Further, a wind guide duct may be connected to the front side of the mounting shroud in order to completely block heated air circulating in front of the condenser. In this embodiment, a multi-flow type condenser is used, but a so-called serpentine type condenser having a meandering tube may be used.

[0024]

According to the present invention, the condenser can be easily attached to the portion to be attached without using means such as welding, so that the number of working steps and the cost can be reduced. Further, since the mounting means covers the outer periphery of the condenser, it is possible to prevent the heated air blown out of the condenser from flowing forward of the condenser. In addition,
