DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condenser, and more particularly to a condenser for air conditioning of an automobile, and more particularly to a mounting apparatus for an automobile.

[0002]

2. Description of the Related Art Conventionally, a capacitor mounted on an automobile has a bracket provided on a header pipe provided on both sides thereof mounted on a side member, and a mounting foot provided on a side plate provided on a lower end thereof is crossed. It was inserted into the members and fixed to the body. The condenser is connected to a compressor, an expansion valve, an evaporator, and the like by piping to form a cooling cycle, and pressurized refrigerant from the compressor is guided to the condenser through a metal pipe such as steel, where it is cooled and cooled. Is to be

[0003]

There are various types of compressors, such as a vane type, a wobble type, and a swash type. Vibrations generated when the compressor is pressurized have been transmitted to the condenser through a refrigerant or piping. The capacitor itself is a large box, which is likely to resonate due to vibration. When resonated, the vibration is transmitted to the vehicle body, and the vibration propagates into the cabin, and is heard as annoying sound by the driver (occupant).

Accordingly, the present invention provides a capacitor mounting device that does not resonate with vibration from a compressor in order to prevent vibration of the capacitor.

[0005]

A capacitor mounting device according to the present invention is a capacitor having a tube and fins which are alternately stacked and a header pipe at both ends of the tube, and which is provided on the header pipe. While being fixed to the side member of the body with the bracket,
It is arranged at the lower end, and is fixed to the cross member of the vehicle body via an elastic body with a pair of mounting feet provided near the two header pipes of the side plate whose U-shaped opening faces the opposite tube side, Engagement projections are provided on the front and rear surfaces of the side plate between the two attachment legs in a substantially cubic shape, and a plurality of isolators made of an elastic body are inserted into the engagement holes of the side plate and attached, and the tips are attached to the attachment legs. Is brought into pressure contact with the fixed cross member (claim 1).

Accordingly, the isolator attached to the side plate is in press contact with the cross member, thereby preventing the capacitor from resonating due to the vibration of the compressor and preventing the capacitor from being a source of noise. Was. Also, the mounting of the side plate of the isolator has been facilitated.

The isolator has a through hole formed at the center (claim 2).

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a condenser 1 includes a pair of header pipes 2 and 2 and a number of flat tubes 3 joined between the header pipes and communicating one header pipe and the other header pipe. The tubes 3 are stacked at equal pitches in a plurality of stages via corrugated fins 4. On the outermost (upper and lower) sides of the laminated tube 3, side plates 5, 6 described below are arranged, brazed to the corrugated fins 4, and provided so as to be joined between the pair of header pipes 2, 2. Have been.

Each of the header pipes 2 and 2 is provided with a plurality of partition plates 7 for dividing an internal space, and one of the header pipes 2 is provided with an inlet pipe 8 for flowing a heat exchange medium (refrigerant) into a condenser. An outlet pipe 9 for flowing out the heat exchange medium is joined to the other header pipe 2. The heat exchange medium that has flowed into one header pipe 2 through the inlet pipe 8 passes through a plurality of tubes while passing through a predetermined group of tubes, and reaches the outlet pipe 9 of the other header pipe. In the process, heat is exchanged with the air passing between the fins.

The open ends of the header pipes 2, 2 are closed by closing members 13. Further, brackets 14, 14 are provided in the middle of the header pipes 2, 2.
Is fixed to the side members 15 and 15 with screws 16.

The side plate 5 is provided above the condenser 1 and has a flat plate shape. However, the side plate 6 provided below has a U-shape as shown in FIG. Are attached to the side plate 6 near both header pipes, and the tips of the attachment legs 18, 18 are inserted into the cross member 19 via an elastic body (not shown). .
A plurality of (three in the embodiment) isolators 23 are mounted in the middle of the side plate 6, and the ends thereof are pressed against the cross member 19. As shown in FIG. 2 for attaching the isolator 23 to the side plate 5, the engagement holes 21,
An engaging projection 24, 24 of an isolator 23 described below is engaged with the engaging hole 21, 21 and attached thereto.

The isolator 23 is, as shown in FIG.
It is attached to the side plate 6 and has a structure as shown in FIGS. That is, the isolator 23 is three-dimensional and made of an elastic body such as rubber or resin. Engagement projections 24 and 24 are formed on the front and rear surfaces thereof. The rear side is larger. The tip is the cross member 1 described above.
9 is contacted, and the slope is formed so as to have a shape suitable for the contact. Further, a through hole 5 is formed at the center of the isolator 23 in the vertical direction.

In the above configuration, the condenser 1 is composed of the header pipes 2, 2, the tube 3, the fins 4, the side plates 5, 6, the partition plate 7, the inlet pipe 8, the outlet pipe 9, the closing member 13, the bracket 14, and the mounting. It is completed by brazing the legs 18 in an integrated furnace, and after the completion, the isolator 23 is mounted on the side plate 6 before mounting on the vehicle body. When the isolator 23 is pressed with a strong force, the isolator 23 is elastically deformed and the engagement projection 24 is inserted into the engagement hole 21 and engaged.

The capacitor 1 to which the isolator 23 is mounted is mounted at a predetermined position on the vehicle body. That is,
The mounting feet 18, 18 are inserted and fixed at predetermined positions of the cross member 19 via an elastic body (not shown), and the brackets 14, 14
Fix to 5,15. When the capacitor 1 is fixed, the tip of the isolator 23 contacts the cross member 19 so as to be pressed against the cross member 19.

[0016]

As described above, according to the present invention, since the tip of the isolator attached to the lower side plate of the capacitor is pressed against the cross member, the capacitor resonates due to vibration from the compressor. It is possible to prevent the noise from being generated. Further, the mounting of the isolator to the side plate is facilitated from the engagement protrusion formed on the isolator and the engagement hole of the side plate.
