tubular wall distinct from the regions in which said
openings are formed, said established two regions being
disposed approximately symmetrically with each other with
respect to an axial plane passing through said openings;
and
forming said fluid box compartment respective
openings before the transverse partitions are positioned
and immobilized by deformation.
11. A heat exchanger comprising:
a fluid box delimited by a tubular wall of generally
cylindrical shape having a substantially uniform circular
internal transverse section and a perimeter, said fluid
box being separated into compartments by at least one
intermediate transverse partition, each partition having
a generally circular edge portion, said edge portion
matching said tubular wall circular internal transverse
section for sliding movement of said partition
therewithin, the heat exchanger further including a
plurality of tubes, each tube being received through an
opening in a region of the perimeter of said tubular
wall, the edge portion of each partition being surrounded
by said tubular wall, said tubular wall being deformed in
two regions of its perimeter distinct from the region in
which said openings are formed to immobilize each of said
partitions, said two regions being disposed approximately
symmetrically with each other with respect to an axial
plane of the tubular wall passing through said openings.
