Abstract

The invention concerns a header ( 10 ) for a heat exchanger of a motor vehicle, configured to receive heat exchange tubes ( 12 ). The header comprises:
a metal plate ( 18 ) through which the tubes ( 12 ) pass and which has two longitudinal edges ( 26 ) for crimping of the header ( 10 ) to a header box ( 16 ), and a plate ( 22 ) comprising a polymer material placed above the metal plate ( 18 ) and provided with openings ( 42 ) for receiving the tubes ( 12 ).

First claim

The invention claimed is:

1. A header for a heat exchanger of a motor vehicle, configured to receive heat exchange tubes, the header comprising:
a first metal plate through which the tubes pass, comprising:
two longitudinal edges for crimping of the header to a header box; and
a second plate, placed above the first metal plate, comprising:
a polymer material,
openings for receiving the tubes, and
stiffening means for the header box; wherein said stiffening means comprises receiving openings for studs; the studs being arranged in the header box.

2. The header as claimed in claim 1 , wherein a wall of the second plate is configured such that the ends of the tubes terminate flush with the wall.

3. The header as claimed in claim 1 , wherein the second plate has a flat form and a thickness between 3 and 8 millimeters.

4. The header as claimed in claim 1 , comprising a sealing gasket arranged between the first metal plate and the second plate.

5. The header as claimed in claim 4 , wherein the sealing gasket comprises a flat portion sandwiched between the first metal plate and the second plate, and provided with funnels configured to be slipped over the tubes.

6. The header as claimed in claim 4 , wherein the sealing gasket comprises a peripheral bed intended to form the seal between the header box and the first metal plate or the second plate.

7. The header as claimed in claim 4 , wherein the openings comprise a shoulder for retaining the sealing gasket, configured such that the sealing gasket is pressed against the shoulder when a tube is received in one of the openings.

8. A polymer plate for the header as claimed in claim 1 .

9. A sealing gasket for the header as claimed in claim 4 .

10. A heat exchanger comprising the header box and the header as claimed in claim 1 .

11. A header for a heat exchanger of a motor vehicle, configured to receive heat exchange tubes, the header comprising:
a first metal plate through which the tubes pass, comprising:
two longitudinal edges for crimping of the header to a header box;

a second plate, placed above the first metal plate, comprising:
a polymer material, and
openings for receiving the tubes; and

a sealing gasket arranged between the first metal plate and the second plate,
wherein the openings comprise a shoulder for retaining the sealing gasket, configured such that the sealing gasket is pressed against the shoulder when a tube is received in one of the openings.
