Description

[Detailed explanation of the idea] The present invention relates to improvements in support structures for vehicle heat exchangers.

Generally, a heat exchanger 1 such as an automobile radiator is provided with a liquid pipe 6 inserted through seat plates 4 and 5 in order to flow cooling water from an upper tank 2 to a lower tank 3, as shown in FIG. Heat transfer fins 7 are interposed therebetween, and rain hoses 8 and 9, which are reinforcing plates, are attached to both sides to form a core portion 10.

This core part 10 has members 11.12 fixed on both sides, and these members 11.12 are for attaching the heat exchanger 1 to a fixed part of the vehicle, for example, the chassis, and are provided in through holes 13 and 14. Insert and secure the mounting bolts, etc.

Also, if the model is different, the bracket 1
5 to member 11.12, and this bracket 15
The arm 16 may be installed by opening the aforementioned through hole 13 in the member 11.12 as shown in FIG.
The lower part is fixed to the chassis 17 with a bracket 19 to provide a vibration-proof structure.

However, each of the support structures requires a large number of parts to be installed, and the installation process is troublesome and takes a long time.

In particular, due to variations in dimensions of fixed parts such as the chassis, the fixed position is not always constant and installation in such cases is not easy. remove the
The purpose of this is to provide a support structure for a heat exchanger that is easy to work with and has reliable support.The main feature is that the heat exchanger member is inserted into a frame provided on the outside, and the size is small. The advantage is that it absorbs variations in accuracy and eliminates the need for bolting or mounting brackets.

Hereinafter, the present invention will be explained with reference to the drawings.

Figure 4 (the same parts as in Figure 1 are given the same numbers) shows an example of a heat exchanger according to the present invention, and this heat exchanger A
The heat exchanger 1 is equipped with necessary components such as an upper tank 2 and a lower tank 3 similar to the conventional heat exchanger 1, and is particularly equipped with a frame 20 on the outer periphery.

This frame 20 consists of a base 23 fixed to the chassis 21 with bolts 22, and struts 24 and 24 erected from both ends of the base 23, and the heat exchanger A is mounted between the struts 24 and 24. I support it.

As shown in FIG. 5, the pillars 24, 24 have a pair of guide members 25, 26 protruding inward from the base plate 27 to form a pair of guide grooves 24a, 24a. Guide grooves 24a, 24 of this support 24.24
The flange 28 of member 11.12 is inserted into a.

The members 11 and 12 are formed by bending a flat plate so that the horizontal section has a U-shape, and has two flanges 28 that protrude outward from the sides. It is fitted into the groove 24a.

However, this heat exchanger A is simply connected to both the pillars 24 and 24.
If the heat exchanger A is only inserted from above between the two, the heat exchanger A will move up and down due to vibrations of the vehicle.In order to prevent this, a projection 29 as shown in FIG. 6 is formed on a part of the flange 28, and The post 24.24 is provided with an aperture or recess 30 which engages this projection 29.

The position of this opening or recess 30 is such that the heat exchanger A is located at the base 2.
Any position is sufficient as long as it engages with the protrusion 29 when placed on the protrusion 3.

Next, the effect will be explained.

First, in order to fix the base 23 of the reverse-opening type frame 20 to the chassis 21 with the bolts 22, a pair of columns 24 are erected upward from the chassis.
The flange 28 of the heat exchanger A is inserted using the guide grooves 24 a , 24 a of the struts as guides.

When the lower tank 3 comes into contact with the base 23 due to this insertion, the protrusion engages with the opening or recess 30 on the support column 24 side,
Prevents heat exchanger A from moving up and down.

On the other hand, the movement in the front and back direction is controlled by the guide members 25 and 26 of the support column 24.
This is prevented by the engagement between the flange 28 and the flange 28.

In the above embodiment, the heat exchanger is inserted from above, but it is of course possible to insert the heat exchanger from the side.

In addition, in the case of insertion from the lateral direction, it is necessary to provide the above-mentioned brackets on the upper tank and the lower tank.

As described above, in the present invention, the heat exchanger can be supported and fixed simply by inserting it into the frame, making it easy to assemble the heat exchanger. Because this is done by inserting a flange between the guide grooves formed on both supports, the relative position between the frame and the member does not change at all times. Installation of the heat exchanger is completed by simply attaching the base of the frame to the frame.

Therefore, not only are parts such as brackets unnecessary, but also workability is improved, resulting in excellent effects such as being able to reduce product costs.
