Abstract

PURPOSE: To easily perform an insertion and an arrangement in a header, and also, prevent a defective brazing from happening by a method wherein a plurality of ridge-shaped small protruding line parts which extend in the insertion direction are provided with intervals in the width direction on the front and rear surfaces of a peripheral end protruding part of a partitioning member, and the ridge-shaped small protruding line parts are made to face and brought into contact with the peripheral wall surface which surrounds a slit of the header. CONSTITUTION: A partitioning member 4 is made of aluminum, and is constituted of a partitioning main body 7 being arranged in a hollow part of a header 3, and a peripheral edge protruding part 9 which is placed in a slit 3d for the insertion of the partitioning member of the header 3. Small protruding line parts 10 are respectively formed on the front and rear both surfaces of the partitioning member 4. The small protruding lines 10 extend to the whole body of the partitioning main body 7, not only on the peripheral end protruding part 9, and are formed with intervals on the whole body of the partitioning member 4 in the width direction into a ridge-form extending in the insertion direction of the partitioning member 4. The height of the small protruding line 10 is set at a height which does not generate a defective brazing in respective gap intervals between the peripheral end protruding part 9 of the partitioning member 4 and the peripheral wall surface which surrounds the slit 3d.

とがある。By the way, for example, in this heat exchanger, for the purpose of allowing the refrigerant to meander and circulate in the heat exchanger as shown in the figure, or for the purpose of forming a plurality of independent heat exchange portions. Alternatively, for other purposes, the inside of the header (3) (3) may be divided into a plurality of chambers in the axial direction by a partition member (50).

ものであった。Conventionally, in such a case, as shown in FIG. 8, a slit (3d) extending in the circumferential direction is provided on the peripheral wall of the hollow header (3), and the hollow header (3) is passed through this slit (3d). A plate-like partition member (50) is inserted and arranged in the inside, and the partition member (50) and the header (3) are joined and integrated by brazing at the time of collective brazing. In this case, the partition member (50) includes a partition body (50a) arranged in the hollow portion of the header (3) and a peripheral end protruding portion existing in the slit (3d), as shown in FIG. (50b) with a constant thickness as a whole.

（３）にろう付けされることも求められる。By the way, in the production of the heat exchanger as described above, the partition member (50) is properly and easily and smoothly disposed in the header (3) through the slit (3d). It is required to be inserted and arranged in the arranged state, and at the same time, it is also required to be brazed to the header (3) so as to hermetically seal the inside of the header (3).

より、仕切部材（50）の挿入が厄介なものになる。However, in order to braze the header (3) so that the inside of the header (3) is hermetically sealed, as shown in FIG. 9 (a), the thickness a of the partition member (50) is changed to the header (3). When the partition member (50) is forcibly inserted by substantially matching the gap distance b of the slit (3d) in 3), the partition member (50) and the peripheral wall surface surrounding the slit (3d) may have a frictional resistance. Insertion of the partition member (50) becomes troublesome.

As shown in 2), the partition member (50) is biased to one side in the slit (3d) in the arrangement state,
A large gap is created on the other side in the slit (3d), and this gap causes brazing failure, and the header (3)
It may not be brazed so that the inside is sealed.

Bending one side in the slit (3d), the gap becomes 0.2
If the distance is more than mm, brazing failure will occur.

る。In the above construction, at least at the peripheral end projecting portion of the partition member, a plurality of mountain-shaped small ridge portions extending in the insertion direction of the partition member are provided on the front and back surfaces thereof at intervals in the width direction, and each small convex portion. The ridges are arranged so as to abut against the peripheral wall surface surrounding the slit of the header.
Therefore, in the work of inserting the partition member into the header, since the contact area between the partition member and the peripheral wall surface surrounding the slit is small, the partition member has low friction resistance,
Therefore, it is smoothly and easily inserted into the header. Moreover, after the insertion and placement, it is also prevented that the peripheral end projecting portion of the partition member causes a large gap in the slit rather than in one side, and therefore, in brazing,
The partition member is brazed to the header without defective brazing.

Therefore, in the insertion work of the partition member, the partition member automatically takes the proper posture with respect to the header at least when the insertion is completed, and the insertion work is easily performed. Moreover, after the insertion and arrangement, the peripheral end protruding portion of the partition member is stably held in an appropriate posture without tilting in the slit, and during brazing, the partition member does not cause brazing failure even from its posture surface. Not only is the brazing material properly brazed to the header, but during brazing, the brazing filler metal is drawn toward each small ridge area by the capillary force. As supplied, the partition member is brazed to the header more effectively without brazing failure.

At least at the peripheral end projecting portion of the partition member, a plurality of mountain-shaped small ridge portions extending in the insertion direction of the partition member are provided on both front and back surfaces thereof at intervals in the width direction, and each small ridge portion forms a slit in the header. It is arranged so as to face and abut the surrounding wall surface. Therefore, in the work of inserting the partition member into the header, the contact area between the partition member and the peripheral wall surface surrounding the slit is small, so the partition member has less frictional resistance, and therefore can be smoothly and easily inserted into the header. You can do it. Moreover, after the insertion and placement, it is also possible to prevent the peripheral end projecting portion of the partition member from creating a large gap in the slit rather than in one side. Therefore, in brazing, the partition member can be brazed without failure. You can braze to the header.

る。In particular, a plurality of small ridges are provided on both the front and back surfaces of the partition member at intervals as described above. Therefore, in the insertion work of the partition member, the partition member can be automatically set to the proper posture with respect to the header at least when the insertion work is completed, and the insertion work can be easily performed. Moreover, after the insertion and arrangement, the peripheral end protruding portion of the partition member is stably held in an appropriate posture without tilting in the slit, and during brazing, the partition member does not cause brazing failure even from its posture surface. Not only can the braze be properly brazed to the header, but during brazing, the brazing filler metal is drawn toward each small ridge area by the capillary force.
Sufficient brazing material is supplied, and the partition member can be brazed even more effectively without defective brazing to the header.
