Abstract
A corner assembly arrangement for a heat exchanger is provided. The corner assembly has a manifold having a tubular metal vessel and a side plate consisting of a flat metal plate extending orthogonally to the manifold and attached to an end thereof. The side plate has an end tab that extends in a zigzag pattern from a respective end of the side plate and has a support end in contact with a wall of the manifold. The support end has, according to a plan view, a concavity configured to fit the wall of the manifold.
Description
- This application claims priority to Italian Patent Application No. 102021000017504 filed on Jul. 2, 2021, the contents of which are incorporated by reference in their entirety.
- The present invention relates generally to the field of heat exchangers for automotive applications and more specifically to heat exchangers comprising manifolds formed from metal tubular vessels.
- In said type of heat exchanger, it has been noted that the manufacturing process causes the side plates, which serve to reinforce the pack forming the heat exchanger, to generally have ends that are separated from the manifolds by gaps of varying sizes. This fact is undesirable from a structural point of view.
- One object of the present invention is to provide a device to compensate for tolerances of the heat exchanger and ensure proper contact between the side plate and the manifold.
- For this object, according to the present invention, a corner assembly arrangement for a heat exchanger is provided, comprising
- a manifold comprising a tubular metal vessel, and
- a side plate consisting of a flat metal plate that extends orthogonally to the manifold and is attached to an end thereof,
- wherein the side plate comprises an end tab having a width that is less than the width of the remaining part of the side plate, wherein the end tab extends in a zigzag pattern from a respective end of the side plate and comprises a support end that is in contact with a wall of the manifold, the support end having, according to a plan view, a concavity configured to fit the wall of the manifold, wherein the end tab comprises a descending part extending from the side plate and an ascending part that is connected to the descending part by a bend and provides the support end.
- With the arrangement according to the present invention, the end tab acts as an adapter for the tolerance of the pack in press-fit. Moreover, the contour on the circumference of the manifold, cooperating with the support end of the end tab, prevents the side plate from moving during the production process. Advantageously, the arrangement according to the present invention is also an improvement for bursting pressures.
- Preferred embodiments of the present invention are also described.
- Other features and advantages of the arrangement according to the present invention will become clearer from the following detailed description of an embodiment of the invention, made with reference to the accompanying drawings, provided purely for illustrative and non-limiting purposes, in which:
-
FIG. 1 is a front elevation view of a corner portion of a heat exchanger according to the present invention; -
FIG. 2 is an enlarged scale view of another corner portion of the heat exchanger in -
FIG. 1 ; -
FIGS. 3 and 4 are a perspective view and a plan view of a manifold/side plate assembly, respectively; and -
FIGS. 5-7 are a perspective view, a plan view, and a cross-sectional view (taken along the line B-B ofFIG. 6 ) of a side plate, respectively. - With reference to
FIGS. 1 and 2 , a heat exchanger for automotive applications is depicted, denoted collectively as 1. - The
heat exchanger 1 comprises a plurality ofparallel tubes 11 extending between two opposite sides of the heat exchanger (shown inFIGS. 1 and 2 , respectively), and a first manifold andsecond manifold tubes 11 are fluidly connected to themanifolds tubes 11 in a direction substantially perpendicular to the plane defined by the bundle oftubes 11. For this purpose,fins 17 are interposed between theadjacent tubes 11. - In
FIGS. 3 and 4 , only one end of only one manifold is shown for convenience, but it is to be understood that the end not shown and the manifold not shown have a similar structure to that shown in the drawings. - Each
manifold tubular metal vessel end closure element 13 b, also made of metal material, arranged at each end of thetubular metal vessel - The
heat exchanger 1 further comprises a first side plate and second side plate 19 (“panel”) each arranged at a respective further side of the heat exchanger, orthogonal to the two opposite sides of the heat exchanger at which themanifolds side plate 19 is shown in the figures, but it is to be understood that the one not shown has a similar structure to the one shown in the drawings. - Each
side plate 19 consists of a flat metal plate that extends orthogonally to themanifolds end tab 21 having a width less than the width of the remaining part of theside plate 19. - In general, the structural union between the various metal components of the exchanger described above is achieved by material coupling, such as by welding and/or brazing.
- Specifically, with reference to
FIGS. 3 through 7 , at each of the corners of theheat exchanger 1, each end of themanifolds respective plates 19 in the following way. - Each
end tab 21 extends in a zigzag pattern from the respective end of theside plate 19 and comprises asupport end 21 a in contact with the wall of thetubular metal vessel FIGS. 4 and 6 , thesupport end 21 a has, according to a plan view, a concavity facing therespective manifold - Specifically, the
end tab 21 comprises adescending part 21′, which extends from theside plate 19, and anascending part 21″, which is connected to the descendingpart 21′ by abend 21″′ and provides thesupport end 21 a. For the purposes of the present description, “descending” means that the relevant part of theend tab 21 extends from the elevation of theside plate 19 to approach the bundle oftubes 11 of theheat exchanger 1, ending in thebend 21′″, while “ascending” means that the relevant part of theend tab 21 extends from thebend 21′″ so as to move away from the bundle oftubes 11. The zigzag pattern, therefore, refers to a direction parallel to the longitudinal axis z of themanifold side plate 19. - With the arrangement described above, the
end tab 21 acts as an adapter for the tolerance in the distances between the side plate and the manifold. Further, the curved shape of the manifold, cooperating with the support end 21 a of theend tab 21 prevents theside plate 19 from moving during the production process.
