Claim 6:
7. A heat exchanger comprising at least one plate forming part of the heat exchanger and configured to delimit a U-shaped channel for circulation of a fluid, the at least one plate extending principally along an axis of longitudinal extent and comprising:
a bottom provided with a plurality of protuberances,
a first lateral raised edge which is at least partially formed within a first plane intersecting the axis of longitudinal extent,
a second lateral raised edge parallel to, and formed opposite from, the first lateral raised edge, first and second longitudinal raised edges formed opposite from one another and parallel to one another, and
at least two openings which are configured such that the fluid enters and exits the channel, respectively, the bottom being provided with a rib which extends longitudinally from the first lateral raised edge, the rib being positioned between the two openings,
wherein the rib is of a sinuous configuration; and
wherein the U-shaped channel includes two branches and a base;
each of the two branches being parallel to a corresponding one of the first and second longitudinal raised edges;
the base being adjacent to the second lateral raised edge,
wherein the rib comprises two longitudinal ends, of which a first longitudinal end is in contact with the first lateral raised edge and a second longitudinal end is provided at a non-zero distance from the second lateral raised edge,
wherein the base includes some of the protuberances and, between the second longitudinal end of the rib and the second lateral raised edge, is interrupted only by the protuberances,
wherein the protuberances are organized in a plurality of rectilinear rows of protuberances and a plurality of oblique rows of protuberances,
the rectilinear rows of protuberances being formed along a second direction (D′) which is parallel to the axis of lateral extent of the plate and the oblique rows of protuberances being inclined by a non-zero angle with respect to the axis of longitudinal extent; and
the plurality of rectilinear rows and the plurality of oblique rows are disposed in each of the two branches of the U-shaped channel and in the base of the U-shaped channel,
wherein the second longitudinal end of the rib: is aligned along a first direction parallel to an axis of longitudinal extent of the plate and is further aligned with the first longitudinal end of the rib, wherein the second longitudinal end of the rib terminates in one of the rectilinear rows of protuberances without touching laterally nearest protuberances.
