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

FIGS. 2 and 3 show an aluminum (including alloy) heat exchanger for a car cooler according to an embodiment of the present invention. In these figures, (A) is a heat exchanger main body, and the main body (A) is arranged between a plurality of tubes (1) arranged vertically in a horizontal state and adjacent tubes (1) and (1). Interposed corrugated fins (2)
have. The tube (1) is made of a flat extruded member made of aluminum. The tube (1) may be a porous tube such as a so-called harmonica tube. Also, an electric resistance welded tube may be used without depending on the extruded material. The corrugated fin (2) has substantially the same width as the tube (1) and is joined to the tube (1) by brazing. The corrugated fin (2) is also made of aluminum, and desirably a louver cut and raised.

(3) and (4) are left and right headers. Each of these headers (3) and (4) is formed of one aluminum electric resistance welded pipe having a circular cross section. Tube insertion holes are formed in each of the headers (3) and (4) at intervals along the length direction, and both ends of each tube (1) are inserted into the holes, and are firmly formed by brazing. It is joined and connected. In addition, left and right headers (3)
At the upper and lower ends of (4), lid pieces (5) are respectively attached. Further, a partition plate (6) is provided on each of the left and right headers (3) and (4), and the left header (3) is provided in two rooms.
The right header (4) is divided into three rooms. Due to the installation of the partition plate (6), the refrigerant flowing into the heat exchanger body (A) circulates in a meandering manner over all the refrigerant passages constituted by the tube groups to exchange heat. Incidentally, (12) and (13) shown in FIG. 2 are upper and lower side plates.

An aluminum refrigerant inlet pipe (7) extending downward is brazed and fixed to the upper end of the right header (4), while extending upward at the lower end of the right header (4). An aluminum refrigerant outlet pipe (8) is brazed and fixed. The right header (4) has an inlet pipe (7) below the mounting position of the refrigerant inlet pipe (7).
An aluminum bracket (9), which is used both to reinforce the heat exchanger and to attach the heat exchanger body (A) to the vehicle body, is brazed, and is mounted above the mounting position of the refrigerant outlet pipe (8) in the right header. Is brazed with an aluminum bracket (10) which also serves to reinforce the refrigerant outlet pipe (8) and to attach the heat exchanger body (A).

These brackets (9) and (10) are made of an extruded aluminum material and have an inverted C-shaped cross section having an opening (91a) as shown in FIG. Holding piece (91), a locking piece (92) extending at one end of the holding piece, and a direction opposite to the locking piece in a form substantially linear with the locking piece (92). And an extended mounting piece (93), and an opening (91) of the holding piece (91).
a) is fitted into the right header (4) in an externally fitted state and brazed integrally. The coolant inlet pipe (7) is screwed and fixed to the mounting piece (93) of the bracket (9) via a clamp piece (94). Here, the locking piece (92) of the bracket (9) functions for positioning. That is, when setting the bracket (9) to the right header (4), after the holding piece (91) is fitted to the header (4), until the locking piece (92) comes into contact with the tube (1). Then, the bracket (9) is rotated counterclockwise in plan view via the mounting piece (93). The contact between the locking piece (92) and the tube (1) prevents further rotation of the bracket (9), and the bracket (9)
Are positioned in an appropriate arrangement state. Therefore,
The setting position of the bracket (9) to the header (4) is considered so that the locking piece (92) of the bracket can be locked to at least one tube.

The structure of the lower bracket (10) is the same as that of the upper bracket (9), and the bracket (10) is attached to the header (4) via the holding piece (101) so as to be fitted externally. At the same time, the refrigerant outlet pipe (8) is also fixed to the mounting piece (103) of the lower bracket (10) by a clamp piece (104). In addition, upper and lower brackets (9) (10)
(95) (105) provided on the mounting pieces (93) and (103)
Is a mounting hole for mounting the heat exchanger body (A) to a vehicle body or the like .

By the way, the above brackets (9) and (10)
The refrigerant inlet / outlet pipes (8) and (7) are attached to the heat exchanger body (A) as follows. That is, first, the upper bracket (9) is arranged at a predetermined position of the header and fixed in a temporary assembled state. Next, the pipe end of the refrigerant inlet pipe (7) is connected to the inlet pipe connection hole (11) of the right header (4) (shown in FIG. 1).
And the refrigerant inlet pipe (7) is integrally fixed to the bracket (9) via the clamp piece (94). This eliminates the need to separately provide a temporary fixing jig for fixing the refrigerant inlet pipe. The lower bracket (10) and the refrigerant outlet pipe (8) are also assembled to the right header (4) in the same manner as described above. After assembling the upper and lower brackets (9) and (10) and the refrigerant inlet / outlet pipes (8) and (7), the heat exchanger body (A) is subjected to collective brazing.
(3) and (4), tubes (1), corrugated fins (2), etc. are joined together, and at the same time, the brackets (9) and (10), the right header (4), the tube (1), and the refrigerant inlet / outlet. The tubes (8) (7) and the right header (4) are joined. The batch brazing can be easily realized by using a brazing sheet as the header (3) (4) or further the tube (1). Before assembling the bracket (9) to the header (4), first, the refrigerant inlet pipe (7) is integrally fixed to the upper bracket (9) via a clamp piece (94), so that the inlet pipe (7) is fixed. After the assembly of 7) and the bracket (9) is manufactured, the bracket with the inlet pipe may be arranged at a predetermined position of the header and fixed in a temporary assembled state. In this case, the pipe end of the refrigerant inlet pipe (7) is connected to the right header (4).
It is necessary to assemble the inlet pipe (7) to the bracket (9) in advance so as to match the inlet pipe connection hole (11).

Thus, the heat exchanger body (A) and the bracket
(9) (10), refrigerant inlet / outlet pipes (8) (7) are integrated
The heat exchanger is mounted on the mounting holes (95) of the brackets (9) and (10).
Can be attached to the vehicle body or the like via

In the above embodiment, the case where the refrigerant inlet / outlet pipes (8) and (7) are used as the piping members has been described, but a block member for the refrigerant inlet / outlet may be used.

[0016]

According to the invention, according to the invention, the pipe member is integrally fixed to the bracket for attaching the heat exchanger body to the vehicle body , and the bracket and the pipe member are heated in this state. It is characterized by being brazed integrally to the exchanger body. Therefore, the piping member and the car
There is no need to separately attach the mounting bracket to the body, etc., to the heat exchanger main body. During assembly, the pipe member can be temporarily fixed and fixed only by fixing the bracket, and the pipe member temporary fixing fixture Can be eliminated, so that the mounting operation can be simplified, the workability can be improved, and the production efficiency of the heat exchanger can be increased. Of course,
The attachment of the heat exchanger body to the car body etc. is done via the bracket
The heat exchanger that the bracket originally has
The mounting function of the body is not hindered at all.
