Abstract

The invention relates to an assembly of two parts crimped together by folding at least one portion of peripheral edge ( 12 ) of one so-called first part ( 8 ) over the other so-called second part ( 9 ). Said first part ( 8 ) has a hinge-forming region facilitating the folding of said portion of peripheral edge ( 12 ). The invention also relates to a manifold comprising said assembly and a heat exchanger comprising said manifold.

First claim

The invention claimed is:

1. A manifold of a heat exchanger comprising:
a collector plate;
a cover; and
an assembly of two parts crimped together by folding at least one portion of a peripheral edge of one first part over a second part, wherein said first part has a hinge-forming region including a fold for facilitating the folding of said portion of said peripheral edge over said second part,
wherein said portion of the peripheral edge of said first part has a thinned portion relative to another portion of said first part capable of offering a resistance to the pressure of a fluid in which a start of said fold is provided along an internal side of said first part at the level of a base of said thinned portion, wherein said base of said thinned portion also defines the interface between said thinned region and said another portion of the first part;
wherein said second part is U-shaped with a base and longitudinal wings linked to said base by an incurved region and in which an internal side of said hinge-forming region is facing said longitudinal wings in proximity to said incurved region;
wherein said assembly of said first part and said second part define an internal space and said fold faces said internal space; and
wherein said collector plate constitutes said first part and said cover constitutes said second part.

2. The manifold as claimed in claim 1 , in which the thinned portion extends from said hinge-forming region to the distal edge of said first part.

3. The manifold as claimed in claim 1 , in which the first part has a longitudinal extension dimension and the thinned portion is continuous along said longitudinal extension dimension.

4. The manifold as claimed in claim 1 , in which said thinned portion has a thickness of between 25% and 75% of the thickness of the other portion.

5. The manifold claimed in claim 1 , in which said thinned portion has a thickness of between 40% and 60% of the thickness of the other portion.

6. A heat exchanger, in particular a condenser of a motor vehicle air conditioning system, provided with a manifold as claimed in claim 1 .

7. The manifold as claimed in claim 1 , wherein said fold is concave.

8. The manifold as claimed in claim 7 , wherein said concavity of said fold is in a direction facing said internal space.
