Definitions

  • the present invention relates to an arrangement in a plate heat exchanger, preferably a recuperator for mobile use, that allows the heat exchanger to be mounted on a support or the like on two opposing sides of the heat exchanger.
  • a heat exchanger preferably a radiator for a motor vehicle, is already known from FR 2 504 251, in which horizontal surface-enlarging plates for vertical cooling tubes at the sides or ends are formed with a flange. A mounting arrangement for the radiator is fixed on to these flanges.
  • the object of the present invention is to produce an improved fixing for a plate heat exchanger of the type stated in the introductory part. This is achieved by means of the characteristic features that are apparent from the characterising part of claim 1.
  • the heat exchanger according to the invention is also intended to absorb relatively large inertial forces.
  • the characteristics of the invention mean that the inertial forces are absorbed in the plane of the heat exchanger plates, and in particular where the plates, as a result of the joining process, are best equipped to withstand the inertial forces.
  • the stresses in the form of acceleration forces, vibration stresses and thermal stresses acting on each separate recuperator plate can be successfully transferred to a support.
  • figure 1 shows a perspective view of a set of plates for a heat exchanger, with a mounting arrangement according to the invention.
  • Figure 2 is a section A-A through the set of plates and the mounting arrangement according to figure 1.
  • Figure 3 shows a mounting arrangement according to the invention for a set of plates with single-curved side wall.
  • 1 generally denotes a plate heat exchanger with flow channels arranged between the plates. Of the said channels every second channel is designed to receive the flow of a heat-emitting medium directed vertically.
  • a casing surrounding the set of plates and with inlet and outlet sockets is required.
  • the remainder of the flow channels are designed to accommodate the flow of a heat-absorbing medium.
  • the inlet and outlet flow of the latter medium passes via collecting channels 2, 3, which connect with the through-flow channels for the heat-absorbing medium. How the collecting channels 2, 3 connect with the through-flow channels is not the subject of the present application and will therefore not be explained further.
  • the walls of the collecting channels are formed by flanges arranged on the plates and inclined somewhat inwards towards each channel opening, which with the flanges telescoped in one another, following a joining process form a closed channel wall.
  • the short sides of the plates are also formed with corresponding flanges 7, which are joined to one another in the same joining process.
  • the mounting arrangement comprises, on each short side, generally denoted in figures 1 and 3 by a or b, a metal sheet 8 which is large enough to cover the short side of the set of plates and is provided with reinforcing keys 9.
  • the latter are parallel to one another and parallel to the plates in the set of plates and distributed over the sheet 8, preferably equidistant from one another.
  • Mounting elements 10, in the form of fixing lugs in the embodiment shown, are joined to the metal sheet and at least some of the reinforcing keys.
  • the metal sheet 8 is also joined to the flanges 7 and the reinforcing keys 9 to the metal sheet 8, and the mounting element 10 to the reinforcing keys 9 and the metal plate 8.
  • Figure 3 illustrates that the short sides of the set of plates need not necessarily be plane surfaces.
  • the invention can naturally be modified to suit a single-curved side surface as shown in figure 3, in which the same reference designations are used as in figure 1.
  • This also shows how the ends of opposing reinforcing keys are joined to a strut 12 with the aim of absorbing compressive forces from the set of plates in the heat exchanger.
  • Figure 3 shows only one such strut. There may obviously also be similar struts in the embodiment according to figure 1.

Abstract

La présente invention concerne une configuration d'échangeur thermique (1) à plaques. La configuration permet le montage de l'échangeur thermique sur un support ou analogue, sur deux faces (a, b) opposées de l'échangeur thermique. Les plaques de l'échangeur thermique (1) sont dotées de rebords (7) sur les faces opposées (a, b) au moins. Dans le procédé de fabrication, les plaques sont emboîtées et reliées, au moins au niveau des rebords (7), au moyen d'un procédé d'assemblage. Chaque face opposée de la configuration comprend une feuille de métal (8) couvrant essentiellement la totalité d'une face. Dans le procédé d'assemblage, cette feuille de métal est conçue de façon à être reliée aux rebords (7). Des éléments de montage, par exemple des pattes de fixation (10), sont également reliées à la feuille de métal (8) et aux éléments élastiques de renforcement (9).
