Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a heat exchange for fixing a heat exchanger having a header pipe used for an air conditioner of an automobile or the like to an installation place such as a vehicle body. The present invention relates to a mounting member for a container.

[Prior Art] FIG. 4 is a perspective view of a main part of a conventional mounting member and a heat exchanger.

Referring to FIG. 4, when manufacturing a heat exchanger 10 including a header pipe, a flat tube, and the like, first, a header pipe 1
1. The flat tube 12, the fins 13 and the like are assembled in advance, and the attachment member 1 is temporarily fixed to the header pipe 11 by TIG welding. Thereafter, the heat exchanger 10 is placed in a brazing furnace (not shown) and heated. Thereby, the brazing material coated on each member of the heat exchanger 10 is melted, and each member is welded. Therefore, at this time, the mounting member 1 is completely brazed to the header pipe 11.

As described above, the conventional mounting member 1 is made of a metal plate that can be brazed. Therefore, when the heat exchanger 10 manufactured in this manner is mounted on a vehicle or the like, a space between the mounting member 1 and the vehicle or the like is required. Generally, a vibration isolator 14 is interposed between the two.

[Problems to be Solved by the Invention] As described above, in the conventional mounting member, welding equipment other than the in-furnace welding equipment is required in order to temporarily fix the mounting member to the header pipe by welding, which causes a cost increase. And the shape of the mounting member tends to be more complicated.

On the other hand, at the time of in-furnace welding, a plurality of heat exchangers with attachment members temporarily fixed are arranged and a plurality of heat exchangers are arranged in the brazing furnace in this state. It is necessary to have a large frontage through which a plurality of heat exchangers with temporarily attached mounting members can be passed integrally, and the mounting members become an obstacle when placing multiple heat exchangers in a brazing furnace. In addition, inconveniences such as the inability to arrange a plurality of heat exchangers in a brazing furnace with good space efficiency occur.

Therefore, an object of the present invention is to provide a mounting that does not require temporary fixing, that is, does not require any welding equipment other than in-furnace welding, and that can be mounted on a heat exchanger after welding in a furnace. It is to provide a member.

[Means for Solving the Problems] According to the present invention, a heat exchanger mounting member for fixing a heat exchanger having a header pipe to an installation location is made of a material having vibration isolation properties, and A mounting auxiliary member for sandwiching the pipe so as to wrap the mounting member, a mounting plate mounted on the mounting auxiliary member, and fixing the mounting auxiliary member to the header pipe by tightening the mounting auxiliary member; And a fastener for fixing the heat exchanger.

[Operation] In the case of the mounting member of the heat exchanger according to the present invention, if the mounting auxiliary member is fixed to the header pipe of the heat exchanger together with the mounting plate by the fastener, the mounting member is mounted on the heat exchanger.

Since the mounting auxiliary member is fixed to the header pipe sufficiently firmly by the fastener together with the mounting plate, no in-furnace welding is required, and thus no temporary fixing is required.

As described above, since it is not necessary to weld the header pipe and the mounting member in the furnace, the mounting of the mounting member can be performed after each part of the heat exchanger is welded in the furnace.

Therefore, when welding a heat exchanger in a furnace, it is possible to arrange only the heat exchanger in the furnace without attaching a mounting member in advance.

[Embodiment] FIG. 1 is a front view of a heat exchanger mounting member and a main part of the heat exchanger according to an embodiment of the present invention, FIG. 2 is a bottom view thereof, and FIG.
The figure is a sectional view taken along the line III-III in FIG.

Referring to FIGS. 1 to 3, the mounting member 1 includes a mounting auxiliary member 2, a fastener 3, and a mounting plate 4.

The mounting auxiliary member 2 has a substantially U-shaped planar shape, and is configured so as to surround the header pipe 11 of the heat exchanger 10 so as to surround the header pipe 11 at a central portion thereof. On the other hand, the vertical cross-sectional shape of the mounting auxiliary member 2 is a shape in which the letter C is back-to-back, and the fitting grooves 2a, 2b, 2c, 2d
Are provided, the fitting grooves 2a and 2b are fitted in the flat tube 12a, and the fitting grooves 2c and 2d are fitted in the flat tube 12b. Through holes 2e and 2f for passing the fastener 3 are provided in the mounting auxiliary member 2, and collars 2g and 2h having flanges are mounted in these through holes 2e and 2f. . In the present embodiment, rubber is used as the material of the mounting auxiliary member 2 so as to absorb vibration. Thus, the mounting auxiliary member 2
Is made of a material having an anti-vibration effect, it is possible to omit the anti-vibration material which has been conventionally used when mounting the heat exchanger. In addition, the material of the attachment auxiliary member 2 is not limited to rubber, and may be any material having vibration damping properties.
It may be a synthetic resin plate or the like.

As the fastener 3, a bolt 3a and a nut 3b are used.
The bolt 3a is inserted through the collars 2g and 2h mounted in the through holes 2e and 2f of the mounting auxiliary member 2 and a hole 4a of the mounting plate 4 described later, and screwed into the nut 3b. By tightening the bolts 3a and nuts 3b, the mounting auxiliary member 2 is tightened and securely fixed to the header pipe 11 of the heat exchanger 10, and at the same time, the mounting plate 4 is also fixed to the mounting auxiliary member 2. . The fastener 3 is not limited to the bolt 3a and the nut 3b.
For example, when the attachment auxiliary member 2 is made of a synthetic resin, a tapping screw or the like can be used, and thus the fastener 3 is not particularly limited.

The mounting plate 4 is made of a metal plate and has a substantially crank shape in plan view. As described above, the mounting plate 4
When the auxiliary mounting member 2 is fixed to the header pipe 11 by the a and the nut 3b, the mounting auxiliary member 2 is fixed to the mounting auxiliary member 2 by the bolts 3a and the nut 3b. A hole 4a for inserting the bolt 3a is provided at one end of the mounting plate 4, and a fitting hole 4b is provided at the other end. A rubber bush (not shown) is fitted into the fitting hole 4b. The heat exchanger 10 is fixed to a vehicle or the like by bolts or the like inserted into the rubber bush. This rubber bush is for absorbing vibration, but since the mounting auxiliary member is made of rubber,
Not necessarily.

[Effect of the Invention] The mounting member of the heat exchanger according to the present invention can be mounted after the heat exchanger is welded in a furnace.

For this reason, welding for temporary fixing is not required, equipment for welding other than in-furnace welding is not required, and the factor of cost increase can be reduced.

When the heat exchanger is to be welded in a furnace, only the heat exchanger needs to be arranged in the brazing furnace, so that a brazing furnace with a small frontage can be used. Can be placed efficiently.
