The present invention relates to a fixing device for a heat exchanger for an automobile, and more particularly, to a dustproof structure of an apparatus for fixing a heat exchanger to an automobile body.

A heat exchanger is a device that sends thermal energy of a high temperature fluid to a low temperature fluid. Heat exchangers used in automobiles include radiators, evaporators and condensers, and evaporators and condensers are used for cooling devices. In addition, the radiator is used as a cooling device for cooling the heat generated in the engine of the automobile.

Referring to a conventional fixing device for a heat exchanger for a vehicle, one end of the first bracket 200 is fastened to the side surface of the heat exchanger 100 by the first bolt 220 and the first bracket 200 of FIG. The other end is formed perpendicular to the one end. In addition, one end of the second bracket 250 having the same shape as the first bracket 200 is positioned below one end of the first bracket 200, and the second bolt 230 has a side surface of the heat exchanger 100. The upper end of the other end of the second bracket 250 is in close contact with the lower end of the other end of the first bracket 200 and is positioned in parallel. Hereinafter, the other end of the first bracket 200 is called the first other end 260 and the other end of the second bracket 250 is called the second other end 270.

A first diaphragm 700 is positioned at an upper end of the first other end 260, a second diaphragm 750 is positioned at a lower end of the second other end 270, and an upper end of the first diaphragm 700. In the bottom of the first anti-vibration rubber 550 and the second diaphragm 750 is provided with a second anti-vibration rubber 500, respectively. The first diaphragm 700 has a shape surrounding the upper end, both side ends, and the end of the first other end 260, and the second diaphragm 750 forms the lower end, both side ends, and the end of the second other end 270. The wrapper has a shape, and the side surfaces of the first diaphragm 700 and the second diaphragm 750 are engaged with each other in a Jacque shape.

In addition, a plate 300 is provided at an upper end of the first anti-vibration rubber 550, and a vehicle body frame 400 is positioned at a lower end of the second anti-vibration rubber 500.

The plate 300, the first anti-vibration rubber 550, the first diaphragm 700, the first other end 260, the second other end 270, and the second diaphragm 750 overlapping from the top to the bottom as described above. ), The second anti-vibration rubber 500 and the vehicle body frame 400 are each formed with two through holes at the same position.

As shown in FIG. 3, the first anti-vibration rubber 550, the first diaphragm 700, the first other end 260, the second other end 270, the second diaphragm 750, and the second anti-vibration rubber 500 are provided. The diameter of the through hole is formed to be larger than the diameter of the through hole of the plate 300 and the vehicle frame 400. The first anti-vibration rubber 550, the first diaphragm 700, the first other end 260, the second other end 270, the second diaphragm 750, and the second anti-vibration rubber 500 penetrate through each other. A hollow cylindrical stopper 650 is introduced into the ball. The inner diameter of the stopper 650 is equal to the diameter of the through hole of the plate 300 and the body frame 400.

Meanwhile, a third bolt 600 is introduced into the through hole of the plate 300 to penetrate the stopper 650 and enter the through hole of the vehicle body frame 400. A male screw is formed at a lower end of the third bolt 600, and a female screw corresponding to the male screw is formed at a through hole of the vehicle body frame 400, and a screw coupling part 420 is formed at a portion where the male screw and the female screw are coupled. do.

4 is a cross-sectional view taken along the line C-C of FIG. As shown in FIG. 4, a stopper 650 is positioned on an outer circumferential surface of the third bolt 600, a first other end 260 is located on an outer circumferential surface of the stopper 650, and an outer circumferential surface of the first other end 260. In the first diaphragm 700 is located.

The fixing device of the heat exchanger for a vehicle of the present invention as described above acts as follows.

A portion of the first diaphragm 700 made of steel, the portion of which is fixed to the first anti-vibration rubber 550, is located between the first other end portion 260 and the first anti-vibration rubber 550, and thus the first other end portion 260. And the first anti-vibration rubber 550 directly prevents the first anti-vibration rubber 550 from being worn by frictional heat generated during vibration of the first other end 260, and the second other end. The second diaphragm 750 located between 270 and the second anti-vibration rubber 500 also functions as the first diaphragm 700. In addition, since the side surfaces of the first diaphragm 700 and the second diaphragm 750 are engaged with each other in the shape of a jack, the first and second end portions 260 and 270 separate and vibrate in the horizontal direction. Can be prevented.

The first anti-vibration rubber 550 and the second anti-vibration rubber 500 are compressed by a predetermined range by the third bolt 600 and are generated at the first and second end portions 260 and 270. It acts to absorb vibrations in the direction. In addition, the plate 300 having a larger area in contact with the first anti-vibration rubber 550 than the third bolt 600 is more than the third bolt 600 directly compresses the first anti-vibration rubber 550. It works for efficient compression.

The stopper 650 is formed to have a predetermined length shorter than the length between the lower end of the plate 300 and the upper end of the body frame 400 so that the third bolt 600 is a screw coupling part 420 of the body frame 400. When the first dustproof rubber 550 and the second dustproof rubber 500 are compressed by a predetermined amount of compression, the length of the stopper 650 is lower than the third diaphragm 300 and the vehicle body. Since the length is equal to the length between the top of the frame 400, the third bolt 600 is no longer introduced into the screw coupling portion 420.

The fixing device of the heat exchanger for cars of the present invention by the above-described action is the vibration generated vertically during the vibration generated in the first and second end portion 260 and the second end portion 270 as the vehicle is driven. The first anti-vibration rubber 550 and the second anti-vibration rubber 500 are absorbed in the vertical direction.

However, the vibration generated horizontally during the vibration generated at the first and second end portions 260 and 270 is stopped at the first and second end portions 260 and 270. There is a problem in that it is delivered directly to the weakening the durability of the stopper 650 and the third bolt 600 and not structurally stable.

The present invention is designed to solve the problems of the prior art as described above, the fixing device of the heat exchanger for automobiles of the present invention aims to block the vibration in the horizontal direction of the bracket so that the bracket and the stopper is not in direct contact.

The heat exchanger fixing device of the present invention devised to achieve the above object has a bracket mounted on the heat exchanger body and a bolt for fixing the bracket to the frame of the vehicle, and an anti-dust rubber provided between the bracket and the frame to absorb vibrations. It is configured to include, wherein the anti-vibration rubber absorbs the vibration applied in the vertical and horizontal directions at the same time.

In addition, the anti-vibration rubber is provided on the upper and lower surfaces of the bracket, respectively, a portion of the anti-vibration rubber may be introduced into the through hole of the bracket through which the bolt penetrates to absorb vibration, and a part of the anti-vibration rubber may be a hollow cylindrical shape. .
