[Problems to be solved by the device]

 However, in the case of the conventional capacitor mounting structure as described above, in order to enable the retrofitting and mounting work of the capacitor without any trouble, or to avoid mutual interference between the capacitor and the radiator due to vibration after mounting, There is a problem that a space for disposing the condenser must be set sufficiently large between the front surface and the radiator or behind the radiator, resulting in a wasteful space in the engine room of the vehicle body.

Further, when the condenser is assembled at the time of manufacturing the vehicle, the radiator and the condenser have to be separately assembled to the vehicle body in the above mounting structure, which is not preferable in terms of work efficiency. When inserting a capacitor, there is a risk that the capacitor and the radiator will come into contact with each other and damage each other, and in order to avoid this, careful work is required, and the efficiency of assembly work will be reduced. There was such a problem.

In order to solve the above problems, the present invention can reduce the required installation space for the air-conditioning condenser, and when the condenser is assembled at the time of manufacturing the vehicle, the assembling is performed. It is an object of the present invention to provide a mounting device for a vehicle air-conditioning capacitor, which can perform the work with high efficiency and can easily perform the post-installation work of the capacitor.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has been completed on the basis of a basic idea that a condenser is supported on a tank portion of a radiator arranged adjacent to the condenser.

That is, a mounting device for a vehicle air-conditioning condenser, which has a pair of left and right headers mounted adjacent to a radiator and a plurality of heat exchange tubes whose both ends are connected to communicate with each other. A capacitor supporting mount member is provided on the lower tank of the radiator, and at the same time, the lower end portion of the header of the capacitor is supported on the mount member through at least a fitting structure that does not restrain relative movement in the upward and downward directions. The gist is a mounting device for a vehicle air conditioning condenser.

As the upper support structure, a structure may be adopted in which the side plate or the header on the upper part of the condenser is integrally connected and fixed to the upper tank of the radiator or the side plate via the connecting bracket.

As described above, the fitting structure for supporting the lower end of the condenser header to the supporting mount member from the lower tank of the radiator does not restrain at least the vertical relative movement of the condenser, that is, the vertical movement. It needs to be capable of relative movement in directions.

This is because not only is it possible to fit and support the capacitor on the supporting mount member by dropping it from above, but in the state after mounting the capacitor, the radiator and the capacitor are not supported. In contrast to the difference in expansion and contraction behavior due to the influence of the applied heat, the thermal expansion and contraction of the capacitor is absorbed by the above-mentioned fitting structure part, so that an unreasonable stress acts between the radiator and the connection between them. This is to avoid the danger of causing damage to parts and the like.

Therefore, the lower end portion of the header of the capacitor may be supported so as to be movable up and down with respect to the bearing mount member via an elastic member such as rubber, or alternatively, the bearing mount member. It may be supported so that it is slightly separated from the bottom surface of the base and allows the vertical movement of the young.

【Example】

 The present invention will be described below with reference to illustrated embodiments.

In FIGS. 1 to 5, (1) is a radiator, and (2) is an air conditioning condenser for a vehicle which is disposed adjacent to the radiator and on the front side thereof.

The radiator (1) includes a radiator core (3) composed of tubes and fins, an upper tank (4) provided at an upper end portion of the core (3), and a lower tank () provided at a lower portion of the radiator core (3). 5) as main constituent members, and in particular, both tanks (4) and (5) are made of a strong synthetic resin such as nylon 66.

Then, in the radiator (1), a capacitor supporting mount member (6) for supporting the capacitor (2) is integrally projectingly provided on the front surfaces of both ends of the lower tank (5). There is. The support mount member (6) is a pair of left and right bracket portions (7) and (7) extending in a cantilevered manner from the lower tank (5) and a bottomed cylindrical shape integrally formed between the tip portions thereof. The bracket portion (7) is configured as a plate-like piece having the width direction arranged in the vertical direction, while the receiving portion (8) has an open upper surface. The peripheral wall is formed into a cylindrical shape that widens toward the upper end, and a slit-shaped drain hole (9) is provided in the center of the bottom surface.

On the lower surface of the lower tank (5), a pair of left and right mounting leg portions (10) (10) are integrally projected, and these leg portions are provided with corresponding holes () of the rubber mount (12). 13) to allow the lower tank (5) to abut and support the rubber mount (12), while the lower leg portion of the rubber mount (12) is attached to the vehicle body (14) at a corresponding mounting hole ( The radiator (1) is vertically supported on the vehicle body (14) by being press-fitted and fitted into the vehicle body (11).

On the other hand, in the condenser (2), as shown in FIG. 5, a pair of left and right cylindrical headers (20) (20) are arranged in parallel with each other at a predetermined interval, and both of these headers are arranged. (20) A plurality of flat heat exchange tubes (21) are arranged in a plurality of upper and lower stages with both ends communicating with and connected to (20), and between these adjacent tubes and on the outer side of the outermost tube. The corrugated fin (22) is arranged.

Reference numeral (23) is an inlet pipe, (24) is an outlet pipe, and (25) is a partition plate inserted in the right header (20).

In the above, the lower part of the capacitor (2) is such that the lower end part of the header (20) (20) is the receiving part (8) of the capacitor supporting mount member (6) provided on the radiator (1) side. It is supported by being inserted through an elastic bush (26) made of rubber or the like which is fitted inside. Thus, the lower end of the header of the condenser (2) allows the lower tank (5) of the radiator (1) to move in the vertical direction, while allowing the free movement in the horizontal plane including the front-back direction. It is supposed to be supported under the mating condition that was mechanically blocked.

On the other hand, both ends of the upper portion of the condenser (2) are connected and fixed to the upper tank (4) of the radiator (1) via connecting brackets (27). That is, at the upper end of the condenser (2), a pair of left and right brackets (27 (27)) is attached to a side plate (28) attached to the upper side of the outermost corrugated fin (22), and the bracket (27 The upper end of 27) is integrally fastened and fixed to a female screw hole (29) formed at a corresponding position of the upper tank (4) of the radiator (1) with a mounting bolt (30).

Instead of the brackets (27) and (27), for example, as shown in FIGS. 6 and 7, a pair of side brackets (31) are attached to the left and right headers (20) (20) of the capacitor (2). ) (31) and a pair of side brackets (32) and (32) corresponding to the radiator (1) side may be provided, and these may be fastened and fixed with mounting bolts (30). In this case, it is not always necessary to fasten and fix both upper and lower end portions of the side bracket, but it is sufficient to fasten and fix at least the upper end portion.

(33) is a ring spacer made of a hard material sandwiched between the bracket (27) and the upper tank (4), and (34) is both ends of the upper tank (4) of the radiator (1). This is a short cylindrical mounting projection that is provided on the upper surface of the part, and the other end of a bracket (not shown) whose one end is fixed to the vehicle body side is screwed and fixed, and the radiator (1) is connected and fixed to the vehicle body side. It is a thing.

It should be noted that strip-shaped seal rubbers (35) that are long in the vertical direction are attached to the front sides of the left and right sides of the core (3) of the radiator (1) by adhesion or the like, and the capacitor (2) is attached. In this state, the seal rubber (35) substantially comes into close contact with the rear surface of the header (20) of the capacitor (2) and closes the gap between them. As a result, the capacity of the radiator (1) is prevented from deteriorating due to side leakage of air that has passed through the condenser (2), and harmful metal parts due to vibration of the condenser (2) and the radiator (1) etc. It is supposed that it can prevent mutual interference.

In the illustrated embodiment, the capacitor (2) is arranged on the front side of the radiator (1) as the most general type, but if necessary, it is arranged on the rear side. It may be done. In this case, it goes without saying that the mounting mount member (6) is provided on the rear surface side of the lower tank (5).

Further, in the present invention, the support structure of the lower portion of the capacitor (2) is such that the lower end portion of the header of the capacitor (2) is mounted on the support mount member (6) projecting from the lower tank (5) of the radiator (1). As long as they can be engaged and supported in a state where at least vertical movement is not restricted. Therefore, the present invention is not limited to the structure of the illustrated embodiment, and various design changes are allowed. For example, the support mount member on the lower tank (5) side is formed in a U-shaped cross section, By arranging these so as to face each other, the lower ends of the left and right headers (20) and (20) of the condenser (2) are fitted together to prevent free relative movement in the horizontal plane. Is also good.

Furthermore, the lower tank and / or the upper tank of the radiator that supports the condenser is not limited to synthetic resin and may be metallic. In that case, the bearing mount member may be integrally attached to the tank by welding or other suitable fixing means.

[0028]

[Effect of device]

 As described above, this invention adopts the lower bearing structure of the condenser arranged adjacent to the radiator by fitting it to the supporting mount member provided in the lower tank of the radiator. The front side or the rear side of the radiator can be placed in close proximity to each other, and as compared with the conventional case where the condenser can be directly supported directly on the vehicle body, the condenser disposed in front of or behind the radiator. It is possible to reduce the required installation space for.

That is, since the condenser is integrally supported by the radiator, the vibration directions of the radiator and the condenser are substantially matched with the vibration of the vehicle body, and the two do not interfere with each other even if they are close to each other. Also, even when the condenser is retrofitted after mounting the radiator on the vehicle body, by inserting the condenser from above into the installation space along the front side or the rear side of the radiator, the condenser is installed. The lower end of the capacitor can be relatively easily adapted to and supported by the mounting member for supporting the radiator side, and even if the installation space for the capacitor is small, there is no particular hindrance to the assembly. . Therefore, the useless space generated in the engine room of the vehicle body can be further reduced.

Further, in the case of assembling the condenser together with the radiator at the time of manufacturing the vehicle, the condenser may be previously supported by the radiator to bring them into a combined state, and then the both may be assembled together in the vehicle body. Therefore, compared to the conventional case where the radiator and the capacitor have to be individually assembled, the assembly work efficiency can be improved and at the same time, the two interfere with each other and damage each other. By eliminating such fears, it is possible to quickly and efficiently perform assembly work.

In addition, since the support at the lower end of the capacitor does not restrain the vertical movement of the lower end of the capacitor, even if the upper end of the capacitor is integrally fixed to the radiator side, The expansion and contraction behavior due to the thermal effect of the capacitor itself is not absorbed by the lower support structure part above, and undue stress is not applied to the radiator side. Therefore, the mounted state of the capacitor can be always kept stable, and there is no risk of damaging its supporting member or radiator.
