Definitions

  • the present invention relates to a side plate for a heat exchanger and a heat exchanger according to claim 1 and claims 5 and 10, respectively.
  • heat exchangers for vehicles which have a manifold and a tank connected by tubes, the tubes being spaced apart by fins, and side plates giving rigidity.
  • the fins provide a large surface area heat transfer and a support for the tubes.
  • Such heat exchangers can be used as radiators or as condensers, but also in a number of other applications, particularly as charge air coolers.
  • Side plates are particularly important during the construction and handling of the exchanger heat. These side plates can be used to gather the fins and tubes to form a core of heat exchanger before fixing to the distributors manifold and tank. As it is better to provide the outer tubes of a fin on their outer edge to ensure good heat transfer, the plates can be attached to each of the two wings exterior.
  • the whole obtained is brazed in an oven.
  • the brazing coating applied on the bottom components so that at cooling, the components are attached to each other.
  • the side plates known in the prior art may be various shapes, for example an elongated flat plate or a curved plate on each side of the mounting surface. They may also have reinforcing ribs. of the (2) Suitable materials are aluminum or aluminum alloys.
  • a first problem that can appear is the "falling fins" which takes place between the fins and the side plate during the melting period in the oven.
  • the wing starts moving from a centered position symmetrically with respect to the center of the side plate at an eccentric position.
  • the edge of the wing which is facing the nucleus is lower than the normal face of the nucleus on one side and above that normal face on the opposite side.
  • the fins fall occurs when the force of gravity is greater than the residual friction force in the end zone of the fin in contact with the tubes and the side plate.
  • radiator fins that roll up on the end radius of the tube but this is not always effective.
  • Other fins use an element cooking frame that extends close to the surface of fin, but this may cause discolouration at the kernel surface or a crater if an accumulation of coating is present.
  • a second problem is that of the "dissolution of "It is necessary to carry out the soldering operation in reducing atmosphere to avoid the production of oxides metal, because it would weaken the brazed joints.
  • the nature of the coating is such that this causes a diffusion of the neighboring material of it, that is to say the outer fins, which weakens the fin material and therefore the structural stability of the heat exchanger.
  • a third problem is that the materials of a chassis cooking, often including strips or wires, cause discoloration when they are very close to coated surfaces.
  • the chassis material is in contact with the side plates, it tends to make itself gather the coating material near the point of contact. This state is called “craterization”, and this results in marks on the surface of the side plates. These phenomena reduce the aesthetic qualities of the heat exchanger.
  • An object of the present invention is therefore to at least partially mitigate the difficulties of art prior.
  • a side plate according to claim 1 According to a first aspect of the present invention, it is provided a side plate according to claim 1.
  • each said sidewall portion interior extends substantially perpendicular to the said flat soul part and has an outer face.
  • said outer face of said portion inner side wall is contiguous with an outer face of said core portion, said side plate having in addition to solder coating material applied to said outer face of said core portion.
  • said solder coating material is applied only on said outer face of said soul part.
  • Figure 6 is a partial cross section of a heat exchanger of the prior art.
  • This one includes a generally C-shaped side plate 1 which is formed from a single sheet of material that is folded on each side in one thickness.
  • This side plate thus has two opposite side walls spaced apart by a wall basic right. It can also include a rib of reinforcement 3 formed by folding the material towards the outside of the heat exchanger.
  • a heat exchanger core 2 for a vehicle is shown attached to a distributor 4 and a lower distributor 6.
  • This core is consisting of multiple tubes 8 spaced by fins 12 and opposite side plates 18.
  • the two distributors are placed parallel to each other, the tubes 8 connecting them and being perpendicular to them.
  • the tubes have a section narrow rectangular (with rounded corners), so they have two flat sides 10.
  • a series of sinuous fins 12, 16 are placed between the flat sides 10 of the neighboring tubes on along substantially the entire length of the tubes.
  • a coolant circulates in the tubes 8 from a partially formed collector by the upper distributor 4 to a tank formed in partly by the lower distributor 6.
  • the fins 12, 16 are in contact with the tubes to provide greater heat sink surface of the cooling fluid.
  • they provide structural support for the tubes 8, which is important because the coolant can to be under pressure.
  • the invention is also applicable to heat exchangers used as air coolers of supercharging, where pressurized air coming for example a turbocharger is cooled by passing through the exchanger heat.
  • each side plate includes a generally flat elongate soul portion base wall 20, at the opposite lateral ends of which join the inner sidewall portions 30, 31 which extend substantially perpendicular to the plan of the base wall 20.
  • the two wall parts internal sidewalls 30, 31 extend substantially from the same amount from the plane of the front wall 20 to go back on themselves to form wall parts respective outer side members 32, 33.
  • the wall parts inner sidewalls 30, 31 have outer surfaces, and the outer sidewall portions are located on the along the outer surface of the sidewall portion respective interior.
  • the side plate has a basic wall of simple thickness with wing portions 24, 22 of double thickness extending on either side of it.
  • the base wall has a outer face 23 which is in contact with the fin 16, and an inner face 21.
  • one of the 32 outer sidewall parts only goes up to level of the inner face 21 of the base wall 20, while the other outer side wall portion 33 extends beyond the outer face 23 of the base wall 20 to form a wing support portion 26 which extends along the side of the fin 16.
  • Each side plate 18 is made of a single piece of material, preferably aluminum or aluminum alloy, provided on one side with solder coating. This side corresponds to the outer face 23 of the base wall 20, the outer face of the inner wall parts, the face inside of the outer wall parts and the part of fin support, that is to say faces that are in contact with other sides of the side plate or with 16. The sides of the side plate that are exposed to the view are left uncoated.
  • the side plate has several advantages. First instead, as the wings are of double thickness, they give to the side plate better stiffness than would a wing of simple thickness. That means we can take for the side plate a smaller material thickness and get the same rigidity and the same support with a thicker side plate with wings of a single thickness. The reduced thickness leads to material expenditure reductions.
  • the coating may also be possible to reduce the amount of brazing coating.
  • the coating when the coating is applied by a hot-rolled process, it is accepted that its minimum thickness is 3% to 5% of the thickness of the matter on which it is applied; therefore, the reducing the thickness of the material allows for a reduction the thickness of the coating.
  • the minimum thickness the coating itself is not determined by the weight of the the material but by the need to maintain a coating sufficient during the brazing operation of the core. In all case, reducing the thickness of the coating can reduce the dissolution of the fin.
  • a second heat exchanger has a core thickness less than the width of the distributors.
  • This heat exchanger has a distributor plate upper 104 and a lower distributor plate 106 which are connected by a series of tubes 108. These tubes have a narrow rectangular section (with rounded corners), so that they have two flat sides 110. A series of fins sinuous 112 are placed between the flat sides 110 of the neighboring tubes along substantially the entire length of the tubes.
  • the plate side has a base wall 120 and two wings 124, 128.
  • Each plate 118 has a first rear wing 124 which extends straight line between the rear of the upper dispenser 104 and the rear of the lower distributor 106.
  • the front wing 128 has a first region 122 which generally extends in parallel at the rear wing 124 about four fifths of the length of the side plate, the spacing between the wings and the width of the base wall here being the width of the core.
  • the base wall of the side plate widens outward until a width corresponding substantially to that of the distributor upper 104 and extends to this distributor on a region of constant width.
  • the front wing 128 has a an outwardly inclined region 130 which extends to a upper region 132 parallel to the rear wing 124, but spaced from it substantially the width of the dispenser superior.
  • the rear wing 124 is of double thickness similar to the wings 24 of the first embodiment.
  • the first region 122 of the front wing has a portion folded back that extends to form a part of fin support, as discussed in connection with FIG.
  • the upper region 132 of the front wing consists of a only thickness of the material of the plate, and in this region, the base wall 120 extends forward, as shown, 116.
  • Each elongate zone has a portion cut out curved back to form a support leg of fin 134.
  • the tabs 134 support the fins 116 to one end and the wing support part of the wing 128 supports these towards the other end.
  • the inclined region 130 is also of simple thickness, folded at the required angle.
  • a third embodiment of the invention is visible in partial sectional form in FIG. 5.
  • This embodiment is similar to the second realization but there is provided an additional leg 136.
  • This leg is attached to the face 120 of the side plate 118 and is located in a hollow of the fin 116.
  • This construction has the advantage compared to the prior art, in addition to providing support structural for the core, to also provide support for the fin to prevent it from falling.
