Abstract

(57) [Abstract] [Purpose] To make the mounting structure convenient when the heat exchanger is fixedly installed on the vehicle body side or the like, and prevent damage to the mounting structure due to vehicle vibration. [Structure] A plurality of refrigerant tubes 2, 2, ... Are arranged in parallel between a pair of left and right header pipes 1, 1 (the right half is not shown), and fins 3, 3 are interposed between these tubes. Between the two adjacent refrigerant tubes 2 and 2, and
The bracket 4 is inserted between the header pipe 1 and the fin 3. To fix the heat exchanger on the vehicle body side or the like, the bolts inserted through the holes 5 of the bracket 4 are fixed to the other brackets, and the other brackets are further fixed to the vehicle body side or the like.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat exchanger such as a parallel flow condenser for an automobile air conditioner.

[0002]

[Prior art]

 In the mounting structure of the heat exchanger described in Japanese Utility Model Laid-Open No. 2-36785 to a vehicle body, a plurality of refrigerant tubes are arranged in parallel between a pair of header pipes, and fins are interposed between these refrigerant tubes. Via a bracket that has a fitting portion that fits on the outer periphery of the refrigerant, an abutting piece that abuts the side portions of the refrigerant tubes and fins that are arranged in parallel, and an insertion piece that is inserted between the refrigerant tubes that are arranged in parallel. The heat exchanger is fixed to the vehicle body by bolts and nuts.

[0003]

[Problems to be solved by the device]

 In the conventional mounting structure of the heat exchanger to the vehicle body, the bracket is fixed directly to the vehicle body side with bolts, which is not possible depending on the vehicle body side structure and space. Due to the vibration of the, damage due to rubbing between the bolt and the refrigerant tube has occurred.

Therefore, the present invention seeks to provide a bracket structure for a heat exchanger that does not cause the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 According to the present invention, a plurality of refrigerant tubes are juxtaposed between a pair of header pipes, fins are interposed between the refrigerant tubes, and holes for attaching fixing members such as bolts and nuts between the two tubes are provided. A bracket structure of a heat exchanger in which a bracket having the above is interposed and another bracket is fixed to this bracket to be fixedly mounted on the vehicle body side is configured to solve the above problem.

[0006]

【Example】

 In FIG. 1, a plurality of refrigerant tubes 2, 2 ... Are arranged in parallel between a pair of left and right header pipes 1, 1 (the right half is not shown), and fins 3, 3 are interposed between these tubes. 2 shows a state in which the bracket 4 is mounted between the two adjacent refrigerant tubes 2 and 2 and between the header pipe 1 and the fin 3.

As shown in FIGS. 2 (A) to 2 (C), the structure of the bracket 4 is such that a hole 5 for inserting a bolt is formed and a collar 6 is formed on one side of the spider in a small direction in which the bolt is inserted. The flange 6 serves as a stopper when the bracket 4 is inserted between the refrigerant tubes 2 and 2. A curved surface 7 is provided on one side surface of the bracket 4, and the curved surface 7 is joined to the cylindrical surface of the header pipe 1.

To fix the heat exchanger on the vehicle body side or the like, the bolts inserted into the holes 5 of the bracket 4 are fixed to another bracket, and the other brackets are further fixed to the vehicle body side or the like. Moreover, as shown in FIG. 3, two brackets 4 and 4 are inserted in various places of the heat exchanger, and another bracket 8 is attached to these two brackets 4 and 4 by bolts or rivets. Then, the bolts are inserted into the holes 9 of the other bracket 8 and fixed to the vehicle body side.

FIG. 4 shows a bracket according to another embodiment of the present invention. (A) shows a bracket 10 in which a screw member 11 is embedded, and (B) shows a bracket 12 provided with a screw hole 13 by modifying the design of (A).

The brackets 4, 10, 12 are brazed integrally with the heat exchanger (header pipe 1, refrigerant tube 2, fins 3) or after the heat exchanger is brazed, a header pipe, a refrigerant Insert between tubes and fins.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the following outstanding effects can be achieved as compared with the conventional technology.

(1) Another bracket is fixed to the bracket to fix the heat exchanger on the vehicle body side, so that the mounting structure is convenient.

(2) Since the bracket is secured between the two tubes, damage due to rubbing between the bolt and the refrigerant tube due to vibration of a vehicle such as an automobile does not occur.

(3) Since the bracket is interposed between the two tubes, the bracket has a spacer function for preventing the refrigerant tube from being displaced.

(4) Since the bracket is interposed between the two refrigerant tubes, the positioning accuracy is improved.
