Abstract

The invention relates to a manifold ( 1 ) for a heat exchanger ( 3 ), in particular for a motor vehicle, said manifold ( 1 ) comprising a tubular wall ( 5 ) and at least one separating partition ( 7 ) partitioning the manifold ( 1 ), said tubular wall ( 5 ) comprising at least one slot ( 11 ) formed over a portion of its cross section and able to allow an insertion of said separating partition ( 7 ), the separating partition ( 7 ) comprising an internal part ( 21 ) inserted into the tubular wall ( 5 ), said internal part ( 21 ) having a periphery provided with a first portion ( 21 a ) and a second portion ( 21 b ) situated facing the tubular wall ( 5 ), said second portion ( 21 b ) being adjacent to at least one deformation of the tubular wall, such that an internal cross section of the tubular wall ( 5 ) corresponds to the perimeter of the partition along the second portion ( 21 b ).

First claim

1 . A manifold for a heat exchanger for a motor vehicle, said manifold comprising:
a tubular wall; and at least one separating partition partitioning the manifold, said tubular wall comprising at least one slot formed over a portion of its cross section and able to allow an insertion of said separating partition, the separating partition comprising an internal part inserted into the tubular wall, said internal part having a periphery provided with a first portion and a second portion situated facing the tubular wall, said second portion being adjacent to at least one deformation of the tubular wall such that an internal cross section of the tubular wall corresponds to the perimeter of the partition along the second portion.

2 . The manifold as claimed in claim 1 , in which said tubular wall is cylindrical having an external diameter d of less than or equal to 12 mm.

3 . The manifold as claimed in claim 1 , in which said first portion extends over the length of the slot and the second portion extends over a complementary part of the first portion over the periphery of the tubular wall.

4 . The manifold as claimed in claim 1 , in which the slot extends over a diametrical section of the tubular wall.

5 . The manifold as claimed in claim 1 , in which said deformation of the tubular wall comprises two annular beads bordering said second portion.

6 . The manifold as claimed in claim 1 , in which said annular beads are shaped portions of the tubular wall.

7 . The manifold as claimed in claim 1 , in which said first portion of the separating partition comes into contact with the external periphery of the tubular wall in the region of said slot.

8 . The manifold as claimed in claim 1 , in which said first portion of the separating partition comprises a part protruding from the tubular wall in the region of said slot.

9 . The manifold as claimed in claim 8 , in which said protruding part comprises a flattened portion perpendicular to a central plane P of the slot, said protruding part comprising two opposing rectilinear edges, on both sides of the flattened portion parallel to said central plane P of the slot.

10 . The manifold as claimed in claim 1 , in which said separating partition is fixedly locked to the tubular wall.

11 . The manifold as claimed in claim 10 , in which said partition and/or the tubular wall comprises a local deformation in the region of the slot.

12 . The manifold as claimed in claim 1 , in which said slot is cut out to dimensions less than the diameter d of the tubular wall, such that when the separating partition is mounted by force in the slot it is held trapped on the tubular wall.

13 . The manifold as claimed in claim 1 , in which said separating partition is provided with two opposing, for example substantially diametrical, notches and said lateral wall comprises shaped portions penetrating said notches.

14 . A heat exchanger for the cooling of batteries, comprising at least one manifold as claimed in claim 1 .

15 . A method for preassembly of a tubular wall of a manifold for a heat exchanger for a motor vehicle, and a separating partition partitioning the manifold, the method comprising:
insertion of the partition into the slot; and deformation of the tubular wall, such that an internal section of the tubular wall corresponds to the perimeter of said second portion, wherein said tubular wall comprises at least one slot formed on a portion of its section and capable of permitting an insertion of said separating partition, and the separating partition comprises an internal part capable of being inserted into the tubular wall via the slot, said internal part having a periphery provided with a first portion and a second portion designed to be brought opposite the tubular wall.
