Definitions

  • the present invention relates in general to the field of air conditioning condensers for automotive applications.
  • a corner junction arrangement for a heat exchanger according to the preamble of claim 1 is known from JP 11337290 .
  • the need is commonly felt to design ever more compact components without adversely affecting their performance and their structural features.
  • the condensers several solutions have been proposed in which the side plates (otherwise called "side panels") and the headers are configured in a different manner. On the one hand, not to take up space in the active part of the condenser, i.e. the fins and tubes, it is desired that the side plates be as thin as possible; however, this must not compromise the structural integrity of the assembly.
  • One object of the present invention is therefore to provide a device to configure a condenser, or more generally a heat exchanger, in such a way as to satisfy the requirements listed above, and to guarantee an adequate contact between the side plate and the header.
  • a corner junction arrangement is proposed for a heat exchanger, comprising
  • the arrangement according to the invention guarantees the structural union between the header and the side plate, since it has a wide area of contact between such elements, an area that only marginally affects the tolerances in the spacing distances between the headers. Furthermore a compact installation may be obtained, since it is possible to ensure that the overall height of the exchanger in fact corresponds to the height of its heat-exchange core, without reducing the space available for tubes and fins.
  • a heat exchanger in particular a condenser for automotive applications, indicated collectively at 1.
  • the heat exchanger 1 comprises a plurality of parallel tubes 11 extending between two opposite sides of the heat exchanger (respectively represented in figures 1 and 2 ), and a first and second manifold 13, 15 respectively positioned at each of said two opposite sides of the heat exchanger.
  • the tubes 11 are fluidly connected to the headers 13, 15 for the transport of a cooling fluid to allow such fluid to exchange thermal energy with a gaseous fluid, in particular air, which is made to pass between the tubes 11 in a direction substantially perpendicular to the plane defined by the tube bundle 11.
  • fins 17 are interposed between the adjacent tubes 11.
  • Each header 13, 15 includes a metallic tubular vessel 13a, 15a extending along a respective longitudinal axis z, and an end closure element 13b, 15b, also of metallic material, arranged at each end of the tubular vessel 13a, 15a (in the figures, for convenience only one end of the headers is shown).
  • the tubular vessel 13a, 15a has, at each of its ends, a collar wall portion 13c, 15c projecting beyond the end closure element 13b, 15b, in which an axial slot 13d, 15d is formed (visible in figures 3-8 ).
  • the end closure element 13b, 15b is a flat element, or baffle, of metallic material, and is inserted in a transverse slot 13e, 15e (shown in figures 2 , 3 , 7 and 8 ) formed at the foot of the collar wall portion 13c, 15c of the tubular vessel 13a, 15a and intersecting with the axial slot 13d, 15d.
  • the end closure element 13b, 15b has a flat surface (indicated at 13f in figure 3 ), which extends radially from the center to the periphery of the end closure element 13b, 15b at the axial slot 13d, 15d formed in the collar wall portion 13c, 15c of the tubular vessel 13a, 15a.
  • the exchanger comprises furthermore a first and second side plate 19 ("side panel") each arranged at a respective further side of the heat exchanger, orthogonal to two opposite sides of the heat exchanger on which are positioned the headers 13, 15.
  • side panel a first and second side plate 19
  • Each side plate 19 is constituted by a flat metal plate which extends orthogonally to the headers 13, 15 and has at each of its ends an end tab 21, 23 with a width less than the width of the remaining part of the side plate 19.
  • the end tab 21, 23 has a boss (indicated with 21a in figure 3 ) that forms a protrusion from a side of the side plate, and correspondingly a cavity on the other side.
  • the end tab 21, 23 has a rounded distal edge (indicated with 21b in figure 3 ).
  • the structural union between the various metallic components of the heat exchanger described above is obtained by coupling the material, for example by welding and/or brazing.
  • each end of the headers 13 and 15 is joined to one of the respective plates 19 in the following manner.
  • Each end tab 21, 23 of the respective side plate is inserted within a respective axial slot 13d, 15d formed in the collar wall portion of the tubular vessel.
  • Each end tab 21, 23 of the respective side plate is joined by means of material coupling, in particular by brazing, to the end closure element 13b, 15b at the respective flat surface 13f of the same.
  • each end tab 21, 23 of the respective side plate is placed in contact with the flat surface 13f of the end closure element 13b, 15b via the respective boss 21a (see in particular figures 5 and 6 ).
  • the collar wall portion 13c, 15c of the tubular vessel 13a, 15a has a height equal to a maximum axial dimension of the end tab 21, 23 of the side plate, calculated taking into account the extension in the axial direction of the boss (see in particular figures 5 and 6 ). With this, it is possible to make a heat exchanger in which the overall height of the tube package comprising also the two side plates is equal to the height of the header.
