2. Description of the Related Art Conventionally, for example, as a heat exchanger used in a condenser for a car air conditioner, a porous extruded flat tube called a harmonica tube is bent in a meandering shape, and fins are arranged between parallel parts to form a core. The so-called serpentine type heat exchanger having the above structure has been used. However, in such a serpentine heat exchanger, since the heat exchange medium passage is formed by one flat extruded tube, a large passage area cannot be secured, and the extruded tube is bent in a meandering shape. Since the radius of curvature of the bent portion cannot be reduced by more than a certain value, the tube pitch cannot be reduced, which reduces the number of fins interposed between the parallel portions of the tube, resulting in poor fin efficiency. There was a limit to the improvement.

Therefore, as a heat exchanger that replaces the serpentine type, a heat exchanger has been proposed in which flat tubes and fins are alternately stacked and the ends of the tubes are connected to a pair of hollow headers. According to this heat exchanger, since the tube pitch can be freely selected, a large refrigerant passage cross-sectional area can be secured, and the number of fins interposed between the tubes can be increased, which is small and has excellent heat exchange efficiency. You can

By the way, in this type of heat exchanger, in order to circulate the heat exchange medium in a meandering manner like the serpentine type, a partition plate is provided to divide one or both of the headers into a plurality of partition chambers. The heat exchange medium passage formed by the tube may be formed in a meandering passage.

Conventionally, as such a partition plate mounting structure, a header is composed of a plurality of short tubular header units, these header units are combined in the longitudinal direction with a partition plate interposed, and fixed by brazing. Structure, or a structure in which a slit-shaped cut portion is formed in the circumferential direction on the peripheral wall of a single cylindrical header, and a partition plate is inserted into this and fixed by brazing (for example, Japanese Patent Laid-Open No. 62-131195) Etc. were adopted.

Problems to be Solved by the Invention However, in the former structure described above, there is a risk that the number of parts increases and the cost increases, or that the header unit and the partition plate are displaced during brazing. It had a drawback that the work of attaching was troublesome and the productivity was poor.

Further, in the latter structure, after the partition plate is inserted into the slit-shaped cut portion and temporarily set, and then in the handling process until it is brazed and fixed, the partition plate is often removed from the cut portion. In many cases, the normal mounting state cannot be realized due to slipping out or misalignment, and as the number of partition plates mounted increases, the rate of defective products in the manufactured heat exchanger increases. It was

By the way, the partition plate (10) is attached to the headers (3) and (4) as follows. That is, as shown in FIG. 1, the headers (3) and (4) are placed at positions where the partition plates (10) are to be attached, and the partition plates extend in the circumferential direction over substantially the radius thereof.
Slit-shaped notch (11) with width almost equal to the thickness of (10)
Are formed. On the other hand, the partition plate (10) is the header (3)
A shielding part (10a) having an outer diameter equal to the inner diameter of (4) and adapted to the inner peripheral surface of the header to cut off the inside of the header in a transverse manner.
And in the area extending over about half the circumference of the shielding part (10a), it extends outward from the peripheral edge thereof, and the header (3)
(4) is formed in the slit-like notch (11) having a mounting convex edge (10b) located inside and filling the slit-like notch (11). Further, at the central position of the peripheral portion of the shielding portion (10a) adjacent to the mounting convex edge portion (10b), a retaining protrusion (10c) bulging on one side is provided. .
The retaining projection (10c) is formed by bulging a part of the shielding portion (10a) in a circular shape on one side by press working, and the cut portion (11) of the partition plate (10). The partition plate (10) is formed to have a height that allows it to be forcedly inserted into the notch (11) and protrudes slightly above the upper surface of the notch (11) when the partition (10) is inserted into the notch (11). And the partition plate (10) is the fourth
As shown in the figure, the outer peripheral surface of the shielding portion (10a) is brought into contact with the inner peripheral surfaces of the headers (3) and (4), and the mounting edge portion (1
The peripheral end of 0b) is fitted into the headers (3) and (4) from the cutout portion (11) in a state of being fitted to the cutout portion (11).
At that time, the partition plate (10) is hammered with a hammer or the like, and is forcibly driven in until the retaining projection (10c) passes through the notch (11) and is located in the header, as shown in FIG. The projection (10c) is engaged with the inner upper edge of the notch (11). This prevents the partition plate (10) from slipping out later. The partition plate (10) is brazed and fixed to the headers (3) and (4) in this state. Even during this brazing, the protrusion (10c) prevents the partition plate (10) from slipping out and misaligning, and the positioning is performed properly, so that the partition plate (1
0) and the headers (3) and (4) are joined and integrated without a gap, and the outer peripheral surface of the header and the outer peripheral surface of the mounting convex edge portion (10b) of the partition plate (10) are aligned with each other to form an uneven surface. There is no curved surface and the appearance is not damaged.

Advantageous Effects of Invention As described above, the heat exchanger according to the present invention has a partition plate for partitioning the inside of the header to allow the heat exchange medium to flow in a meandering manner. In the state where the partition plate is provided with a retaining projection that engages with the inner edge of the cut portion, the partition plate is forcibly inserted from the notch into the header, and the retainer projection is engaged with the inner edge of the notch portion. This is a structure that is joined and integrated with the header. Therefore, the header can be manufactured integrally, and the number of parts can be reduced as compared with the conventional case where a short header unit is joined in the middle with a partition plate interposed. Moreover, since the partition plate retaining means is formed as a protrusion on the peripheral edge of the shielding portion of the partition plate, which allows the forced fitting into the cut, the partition plate can be fitted by a forceful operation. Not only can it be performed easily, but after the fitting, the partition plate does not come off or the position is displaced, and the position can be properly regulated through the process after the fitting until the brazing is completed. Therefore, in combination with the decrease in the number of parts, the assembly and joining work can be simplified and the productivity can be improved, and the production yield of products can be improved by reliably preventing the generation of defective products due to the improper mounting of the partition plate. sell.
