Definitions
- the technical sector of the present invention is that of heat exchangers configured to perform a heat exchange between a first fluid and a second fluid, more particularly intended to be installed in a motor vehicle.
- a heat exchanger is, for example, a supercharged air cooler.
- a motor vehicle can conventionally be equipped with an internal combustion engine combined with a turbocharger. This causes a rise in the temperature of the intake gas, which affects the correct filling of the combustion chambers of the engine. This is the reason why it is known to complete this configuration by the addition of a heat exchanger, the function of which is to cool the intake gases before their entry into these combustion chambers, which makes it possible to increase the density of the inlet gases and thus improve the stoichiometric ratio in the combustion chambers.
- Such a heat exchanger conventionally comprises a plurality of tubes in which the inlet gases circulate, the spaces between the tubes being for their part traversed by a cooling fluid.
- the inlet gases are channeled by a lid secured to a manifold, the latter being configured to sealingly receive the end of each tube through which the inlet gases enter.
- New supercharging techniques make their appearances. It is thus known to combine the internal combustion engine with two or three turbochargers. This combination is accompanied by an increase in the pressure and the temperature of the inlet gases. The mechanical stresses experienced by the charge exchangers become extremely important, since the pressure of the inlet gases can reach 4 bars. The heat exchangers known to date are therefore not adapted to withstand such pressure or temperature levels, and leaks may appear in particular to the right of the junction which connects the cover to the collector.
- the object of the present invention is therefore to solve the disadvantage described above mainly by reinforcing the peripheral edge of the manifold, the latter being particularly designed to receive and secure by crimping a lid.
- the invention proposes to provide stress recoveries on a component of the heat exchange body, in particular on the tube or tubes through which the inlet gases subjected to high pressure pass.
- the invention therefore relates to a heat exchanger comprising a heat exchange body, at least one cover and a collector connecting the cover to the heat exchange body with a crimping device from the collector and folded on the lid, the heat exchange body comprising a plurality of tubes adapted to channel a first fluid, the manifold comprising a bottom plate surrounded by a lid fastening edge, characterized in that the bottom plate and the edge of fastening delimit a receiving housing of a heel cover, the fastening edge being formed by a lined wall, one end of which is secured to at least one constituent tube of the heat exchange body.
- the fastening of the end of the lined wall on at least one tube thus ensures a recovery of mechanical forces which contributes significantly to increasing the resistance mechanical solidarity edge against the constraints generated by the pressure or the temperature of the first fluid able to circulate inside the heat exchanger according to the invention.
- the heat exchange body may also comprise a multiplicity of dissipation devices interposed between the tubes and in contact with a second fluid able to pass through the heat exchange body.
- the end of the doubled wall is secured to a plurality of tubes. It is intended here the case where the end extends along a longitudinal face of the exchanger, the end then being brazed to a side wall of several tubes bordering the longitudinal face.
- a tube comprises two longitudinal walls joined to one another by two side walls, the fastening edge comprising a strip transverse to the bottom plate and secured against at least one of the side walls. at least one tube over a length of at least 1 mm.
- the end is secured against a longitudinal wall of a terminal tube of the heat exchange body.
- the heat exchange body is finished laterally by a cheek installed at a distance at least equal to 0.1 mm from the doubled wall, this distance being a minimum to avoid brazing between the two elements concerned.
- a dissipation device is interposed between the cheek and the end tube, the dissipation device being at a distance at least equal to 0.1 mm from the doubled wall, this distance being a minimum to avoid soldering between the two elements concerned.
- the exchanger according to the invention can be configured so that a distance at least equal to 2 mm is provided between the bottom plate and the end of the doubled wall. Such a distance makes it possible to form a strut by means of the brazed end on the tube. Such a strut opposes a phenomenon of opening of the fastening edge under the effect of the pressure in the lid, which increases the level of reliability of the sealing by crimping.
- the bottom plate comprises at least one opening in which is housed a tube end, said opening being bordered by a collar turned towards the heat exchange body. Such an arrangement makes it possible to obtain a face of the base plate turned towards the substantially flat cover, which contributes to improving the mechanical strength of the heat exchanger.
- Such an exchanger may comprise a seal installed in the receiving housing, at least between the heel of the cover and the securing edge.
- the lined wall is formed by a first wall and a second wall brazed against the first wall.
- the first and second walls come from the same metal sheet and connected to one another by a fold.
- the second wall is previously separated from the first wall, then reported on it before a soldering step.
- the doubled wall may comprise at least one angle to the right of which is provided a mechanical reinforcement device.
- the latter prevents the angular inclination formed between the two parts of the lined wall which border the angle increases under the effect of pressure.
- the mechanical reinforcement device is in particular a chamfer formed on the angle of the first wall.
- this mechanical reinforcement device is advantageously a fillet formed on the angle of the second wall.
- this reinforcing device can also be formed by the combination of chamfer and leave, formed on one or the other of the walls. Such an arrangement makes it possible to generate shapes that combine to oppose the mechanical stresses that the collector has undergone.
- the first wall may comprise a first band forming a bottom of the housing and a first sidewall delimiting laterally the housing, the first band and the first side being connected by the chamfer.
- the second wall may comprise a second band brazed against the first band, and a second side brazed against the first sidewall, the second band and the second side being connected by a leave chamfer distant .
- the fillet and the chamfer form here the device of mechanical reinforcement, and such a distance between this fillet and this chamfer contributes significantly to increase the mechanical strength of the joining edge.
- the end comprises a fold arranged so that a face of the second wall is brazed against the tube.
- Such an arrangement makes it possible to increase the fastening surface, in particular brazing, between the wall doubled and the tube or tubes, at the end.
- the crimping device may comprise a plurality of crimping tabs from the first wall, which in the final state of manufacture of the heat exchanger, are folded over the heel of the lid.
- the invention may also cover an intake gas cooling system of an internal combustion engine of a motor vehicle, comprising a heat exchanger incorporating any of the features described above, wherein the first fluid is formed by the intake gas of the internal combustion engine, while the second fluid is formed by a flow of air outside the vehicle.
- An advantage of the invention lies in the possibility of increasing in a simple manner the mechanical strength of the collector, in particular of its securing edge.
- the fastening of the end generates an additional contact point on the tubes which then forms a recovery of forces, the latter significantly limiting the deformations of the fastening edge when the heat exchanger is subjected to pressure and / or temperature important internal

- the second fluid passes through the heat exchange body 2 in a direction perpendicular to, or substantially perpendicular to, the direction of movement of the first fluid in the tubes 6.
