Definitions
- the invention relates to a heat exchanger, in particular for motor vehicles, of the type comprising a bundle of finned tubes immobilized relative to a collector-water box assembly.
- the seal between the ends of the tubes and the edges of the manifold holes is generally ensured by a sheet of elastomer or similar material which covers the manifold and which has collars each of which is engaged between a end of a tube and the edge of a manifold hole.
- the immobilization means provided in document FR-A-2 560 368 make it possible to establish a rigid connection between the beam and the collector, which is thus opposed to the relative displacements mentioned previously.
- the immobilization means require notches to be made along the longitudinal edges of the fins or else to provide aligned openings formed through them, which means that structural fins have to be used. particular.
- the means for immobilizing the aforementioned document include tabs molded in one piece with the water box or with the collector, or fingers molded in one piece with the collector, which makes it necessary to manufacture specific parts by plastic molding.
- the object of the invention is in particular to overcome the drawbacks mentioned above.
- the invention proposes, for this purpose, a heat exchanger of the type mentioned in the introduction, in which the immobilization means comprise at least one attached element, interposed between the bundle and the collector-water box assembly, this attached element comprising a first part capable of bearing on the manifold-water box assembly and a second part extending parallel to the direction of the tubes of the bundle and capable of bearing on the longitudinal edges of a group of several fins, located adjacent to the collector.
- the heat exchanger uses at least one insert to immobilize the beam relative to the collector, it is not necessary to provide fins of particular structure or to modify the structure of the collector-water box assembly .
- the heat exchanger comprises at least one pair of opposite elements, each of which has a first part in the form of a leg suitable for being fixed on the water box and a second part in shape of a leg extending parallel to the direction of the bundle tubes. It then suffices to have the elements of the same pair on either side of two longitudinal sides of the beam.
- first part and the second part of each element extend in substantially parallel planes with one another and these two parts are connected by a web.
- each element is advantageously fixed to a boss of the water box, for example by means of a screw or other similar fixing member.
- the immobilization means comprise a plate capable of being interposed flat between the collector and the group of fins, this plate having at least one opening for the passage of tubes of the bundle and comprising at least two legs attached perpendicularly to the plate and adapted to bear respectively on two opposite longitudinal sides of the beam.
- the plate is capable of bearing under a peripheral rim projecting from the collector.
- the plate is suitable for bearing under a central part of the collector, which is framed by a projecting peripheral rim.
- the plate and the legs which depend on it are advantageously formed in one piece, either from a stamped metal sheet, or by molding of a suitable plastic.
- the heat exchanger partially shown in Figure 1 comprises a bundle 10 formed of a single row of aligned tubes 12, provided with planar fins 14 parallel to each other and extending perpendicular to the direction of the tubes 12.
- the tubes 12 have, in the example, a body of oblong section and have circular cylindrical ends 16. The latter are mounted in sealing in the holes 18 of a manifold 20, also called “plate with holes”.
- the collector 20 comprises a peripheral flange 22 formed projecting and terminated by crimping lugs 24.
- the lugs 24 are folded over the peripheral flange 26 of a water box 28 which, in the example, is formed by molding a plastic material. Sealing at the ends 16 of the tubes 12 is ensured by a sheet 30 of elastomer or similar material, which covers one face of the collector and which includes collars 32 clamped between the ends 16 of the tubes and the edges 34 of the holes in the collector .
- the water box 28 defines with the collector 20 an internal volume 36.
- the collector as just described so far, is of a conventional structure.
- Another collector-water box assembly with a similar structure is generally mounted at the other end of the tubes.
- the heat exchanger comprises a single row of tubes, it can happen that the collector-water box assembly moves, by pivoting or twisting, which can cause cuts at the collars 32, whence risk of leakage of the fluid circulating in the heat exchanger.
- the invention makes it possible to overcome these drawbacks by means of immobilization which, in the example, comprise at least one pair of opposite elements 38 arranged on either side of the collector.
- Each of the elements 38 has a first part 40 in the form of a rectilinear tab and suitable for being fixed to the water box 28 by means of a screw 42 passing through the tab 40 and engaging in a boss 45 molded with the box. water.
- the first part 40 extends in a substantially parallel direction of the tubes and it is connected to a second part 44 which extends parallel to the direction of the tubes of the bundle and which is able to bear on the longitudinal edges of a group of several fins 14, adjacent to the manifold.
- the parts 40 and 44 are connected together by a veil 46 suitable for possibly taking support under the flange 22 of the collector 20.
- the water box 28 thus comprises at least one pair of two opposite bosses 45, on which two elements 38 are fixed respectively.
- the respective parts 44 of the two elements 38 come to bear on two opposite longitudinal sides 48 of the bundle.
- the heat exchanger comprises fins, a manifold and a standard type water box.
- At least one insert 50 comprising a plate 52 of generally rectangular shape suitable for being interposed flat between the flange 22 of the manifold 20 and the fin group, that is to say the fin closest to the collector.
- the plate 52 has at least one opening 54, for example of generally rectangular shape, for the passage of at least one tube 12 of the bundle.
- the insert 50 comprises at least two opposite legs 56 attached perpendicularly to the plate 52 and adapted to bear respectively on the two opposite longitudinal sides 48 of the beam.
- the lugs 56 thus play the same role as the lug-shaped parts 44 of the heat exchanger of FIG. 1.
- the insert 50 is, in the example, formed in one piece from a stamped metal sheet, for example an aluminum sheet.
- the element 50 is simply interposed for mounting between the tube bundle and the manifold.
- the heat exchanger comprises at least one insert 60 which is similar to the element 50 in FIG. 2.
- the insert 60 comprises a plate 62 of generally rectangular shape suitable for taking ap meme under the collector 20, and more particularly in the central region thereof as delimited by the peripheral flange 22.
- the plate 62 has, in the example, three openings 64 of rectangular shape each intended to allow passage to a tube of the beam.
- the insert 60 further comprises two legs 66 attached perpendicularly to the plate 62 and adapted to bear respectively on the two longitudinal sides 48 of the beam.
- the legs 66 thus play the same role as the legs 56 of the embodiment of FIG. 2.
- the element 60 as constituted by the plate 62 and the two tabs 66, is formed in one piece by molding a plastic material. As in the case of FIG. 2, the element 60 is interposed for mounting between the last fin of the bundle and the manifold.
- the invention thus makes it possible to produce, in a particularly simple manner, a heat exchanger in which the bundle of tubes is perfectly immobilized relative to the manifold-water box assembly. This prevents the appearance of relative movements likely to occur especially in the case of heat exchangers having a single row of tubes.
- the invention applies very particularly to heat exchangers for motor vehicles, in particular to engine cooling radiators, or to passenger compartment heating radiators.
