Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacitor used in a vehicle air conditioner, and more particularly to a receiver mounting structure.

0002

[Prior Art] The conventional technology regarding the receiver mounting structure of a capacitor is Nippondenso Publication Technical Report No. 43-073 (
(published September 15, 1985),
Fit the bracket 101 into the end of the core part and tighten the screw 10.
2 to fix the bracket 101 (FIG. 2). When attaching a receiver near the capacitor as described above, one end of a bracket 101 is fixed to a holder 103 and the receiver is held at the other end, as shown in FIG.

0003

SUMMARY OF THE INVENTION When a receiver is installed near a capacitor, there is a restriction in that the position where the receiver can be installed is limited depending on the type of vehicle due to the layout within the engine compartment. However, in order to satisfy the above constraints with the conventional receiver mounting structure,
Each time the above-mentioned limited position changes, it is necessary to assemble a holder 103 having a length that satisfies the limited position, which is extremely time-consuming and unreasonable for mass production. If possible, I would like to use holders of the same length to satisfy the above conditions.

Furthermore, if the length of the holder becomes too long as a result of satisfying the above constraints, the vibration of the holder will increase when the capacitor vibrates due to vehicle operation, and the fixed portion between the holder 103 and the bracket 101 will There is also the problem that the parts may come loose or be destroyed.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a capacitor which allows a receiver to be mounted in any position and which has strong durability against vibrations.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a tube through which a refrigerant passes, and a tube connected to the tube to release the heat of the refrigerant passing through the tube. a core portion comprising fins that exchange heat with surrounding air; a mounting member provided at at least two of the four corners of the core portion; a mounting member provided at the one corner and the other corner; The gist of the condenser is a condenser including a bridging member fixed to a mounting member provided on the bridging member, and a receiver fixed to the bridging member and temporarily storing the refrigerant.

[0007]

[Operation] By fixing the bridging member at an arbitrary position on one mounting member and at an arbitrary position on the other mounting member, the receiver can be mounted in any position.

[0008]

[Effects of the Invention] In the present invention, since the bridging member that fixes the receiver is fixed to one mounting member and the other mounting member, it is not necessary to fix the bridging member to only one mounting member to support the receiver. Vibration resistance is stronger than that of Furthermore, by fixing one part of the bridging member to an arbitrary position on one mounting member and fixing the other part of the bridging member to an arbitrary position on another mounting member, the receiver can be mounted in any position. .

[0009]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. First, the overall configuration of the first embodiment will be explained based on FIG. 1. Here, FIG. 1 is a front view showing the general appearance of a capacitor in a first embodiment.

In the first embodiment, the components include a core portion consisting of a header 1 that stores a refrigerant and distributes or collects the refrigerant to a plurality of tubes 2, and a tube 2 through which the refrigerant passes; A multilayer capacitor (hereinafter referred to as a multi-flow (MF) capacitor) having fins 3 that releases heat of the refrigerant passing therethrough and exchanges the heat with the surrounding air is used.

The core portion of the MF capacitor is composed of a plurality of flat tubes, and because the width in the vertical direction of the drawing is shorter than the width in the vertical direction of the drawing, it is easily deformed by external or internal force. In order to prevent the deformation, and as an assembly jig before the core is fired, in general MF capacitors, mounting members are provided at the corners of the core. The MF capacitor used in the first embodiment also has side plates 4, which are mounting members, arranged at two corners of the core portion. Further, the side plate 4 is provided with a plurality of holes.

[0012] A sub-bracket 5, which is a bridging member, is disposed so as to bridge both side plates 4. Further, the sub-bracket 5 is provided with a plurality of holes, and the size of the holes is equal to the size of the hole provided in the side plate. Then, the holes at both ends of the plurality of holes provided in the sub-bracket 5 are aligned with the holes provided in the side plate, and the pins 6 are inserted and fixed.

In order to show the coupling relationship between the side plate 4 and the sub-bracket 5, FIG. 4 is a partial sectional view taken along the line A--A in FIG. As shown in Figure 4, the side plate 4
has a U-shaped cross section, and its side plate 4
A U-shaped sub-bracket 5 that surrounds the outside of the
are combined. A pin 6 is inserted by aligning the hole in the side plate 4 with the hole in the sub-bracket 5. After the pin 6 is inserted into the hole, both left and right ends in FIG. 4 are caulked and fixed.

A receiver 7, which temporarily stores refrigerant liquefied in an MF condenser consisting of a header 1, tubes 2, and fins 3, is held at the other end of a holder 8 whose one end is fixed to the sub-bracket 5. . By the way, regarding the method of fixing the holder 8 and the sub-bracket 5, the holder 8 is provided with a hole of the same size as the hole provided in the sub-bracket 5, and the pin 6 is inserted by aligning both holes. After that, both ends of the pin 6 are caulked and fixed.

Since the sub-bracket 5 that fixes the holder 8 is fixed to the two side plates 4, it has stronger vibration durability than the cantilever receiver mounting structure shown in FIG. Furthermore, the shorter the length of the holder 8, the stronger the vibration durability of the fixed position between the holder 8 and the sub-bracket 5.

Side plate 4 and sub bracket 5
has multiple holes, so if the position where the receiver 7 can be installed differs depending on the car model due to the layout in the engine room, it may be necessary to install the receiver 7 at a fixed position between the side plate 4 and the sub-bracket 5, or between the holder 8 and the holder 8. The receiver 7 can be attached to various positions by arbitrarily selecting a fixing position to the sub-bracket 5, inserting a pin 6, and fixing it by caulking.

Furthermore, since the sub-bracket 5 has a plurality of holes, the ventilation resistance of the air passing through the core portion is reduced, and as a result, heat exchange between the refrigerant and the air is promoted. Further, in the first embodiment, the side plate 4, which is an essential item for an MF capacitor, is used as a mounting member. In other words, MF
In the case of capacitors, instead of providing a separate mounting member, essential items can be effectively used as the mounting member, so it is very economical without increasing costs.

Next, second to fourth embodiments will be explained. In addition to the coupling relationship between the side plate 4 and the sub-bracket 5 as shown in FIG. 4, as shown in FIG. 6 may be inserted and fixed by caulking both ends of the pin 6 (second embodiment).

[0019] Also, the side plate 4 and the sub-bracket 5
In addition to using the pin 6 as a fixing method, as shown in FIG. 6, the end of the sub-bracket 5 may be directly inserted into the side plate 4 and fixed by caulking (third embodiment).

Furthermore, as shown in FIG. 7, the sub-bracket 5
It is also possible to make the length of the sub-bracket 5 such that it slightly protrudes from the core part, make a hole in the part of the sub-bracket 5 that protrudes from the core part, fit a grommet 9 into the hole, and fix it with screws 10. This eliminates the need to separately provide parts for attaching the capacitor body to the vehicle body (fourth embodiment).

In addition, in the first and second embodiments, the fixing portion between the side plate 4 and the sub-bracket 5 and the fixing portion between the sub-bracket 5 and the holder 8 are fixed by inserting pins 6 and caulking, respectively. Bolts can be used instead of pins.
