Definitions
- the invention relates to a heat exchanger which can be produced in particular in the form of an air radiator of supercharging for a motor vehicle.
- the heat exchanger of the invention is of the type describes in the preamble of claim 1.
- the header plate is capped by a manifold so as to provide a clean room to be traversed by a fluid which also circulates in the bundle tubes.
- the tubes are traversed by a fluid which can undergo temperature differences important which therefore lead to differences significant dilation.
- the collar is connected to the rest of the collector plate by a region where the wall of the collector plate is thinned, which allows a deformation of the wall and, by Consequently, an axial clearance of the collar.
- the collar follows the movement of the end of the tube as a function of differences in thermal expansion.
- the collar is attached to the wall of the tube by a part which, in cross section, has a swan neck configuration.
- This neck portion of swan ends with a lip leaning against at least an annular bead formed on the wall of the tube.
- the invention provides a heat exchanger of the aforementioned type which offers a better aptitude for deformation under the effect of differences in expansion and which also does not require tubes with bosses.
- each collar is attached to the rest of the collector plate by an annular fold having substantially a U-shaped section and having a branch which constitutes the collar and another branch which constitutes a connecting branch, and localized thinning is carried out in this branch of attachment.
- this thinning localized is carried out by stamping or removal of material, either on one face of the wall of the collector plate, either on both sides of the plate wall collector.
- the invention applies in particular to a heat exchanger heat in which the header plate and tubes are in aluminium.
- the collar has an elongated shape suitable for receiving a tube flat
- localized thinning is carried out in a region elongated, homologous to that of the collar.
- the heat exchanger of the invention is particularly achievable as a charge air radiator intended to cool an air flow feeding a motor turbocharged.
- the heat exchanger shown in Figures 1 and 2 includes a collecting plate 10 which has a shaped core 12 general rectangular with two longitudinal edges 14 folded back substantially at right angles, to allow the header plate 10 to be capped by a box wall collector (not shown) and delimit a clean room to be traversed by a fluid.
- the collecting plate 10 has a metal wall 16, for example aluminum, which is stamped to form the core 12 and the longitudinal edges 14.
- a plurality of holes 18 which, in the example, have an oblong shape substantially rectangular whose length extends transversely to the core 12, that is to say perpendicular to the edges longitudinal 14.
- the holes 18 are arranged in a single row and are regularly spaced between them.
- Each hole 18 is suitable for receiving one end 20 of a tube 22, in the example a "flat tube", which has a external section adapted to that of the internal section of the hole 18.
- the tubes 22 are metallic, for example aluminum, and their ends 20 are intended to be connected by brazing to the wall 16 of the collector plate 10.
- each hole 18 is bordered by a collar 24 obtained by deformation of the wall 16. This collar extends over an axial length greater than the thickness of the wall 16 to allow a better connection by brazing between the end of the tube and the collector plate.
- tubes 22 are traversed by an air flow which can undergo variations in significant temperatures, where it results in variations in expansion of the tube which can cause stress at the level of the solder connection between the end of the tube and the matching collar.
- the invention provides means to allow movement of the collar relative to the core 12 of the collector plate.
- each collar 24 is attached to the core 12, that is to say to the rest of the collector plate 10, by a fold annular 26 which has a contour homologous to that of the collar and which has, in section, substantially the shape of a U.
- This U has a first branch which constitutes the collar and another branch 28 which constitutes a connecting branch to the core 12.
- This branch 28 has a thinning located A at which the thickness of the wall of the plate is weaker than at the level of the core 12.
- this thinning localized is obtained by stamping or removing material from the outer face 30 of the plate collector 10, while its inner face 32 has not undergone material removal.
- the only difference is that the thinning A has a reduced thickness.
- the collet 24 may struggle, in the direction of arrow F, relative to the core 12 due to the thinning A made in the thickness of the wall and in a region ring surrounding the collar.
- solder connection (not shown) between the end 20 of the tube and the collar 24 will not undergo stresses likely to cause cracking or solder break.
