Definitions
- the invention relates to a brazed plate heat exchanger.
- a brazed plate heat exchanger may be of the engraved plate, separator plate and wave type, or have a combination of engraved plates and separator plates and waves.
- the invention is particularly advantageous for exchangers made of carbon steel, stainless steel or refractory alloy.
- the engraved plate heat exchangers consist of a stack of plates on which etching has been previously performed on one side and one of the faces is coated with a solder coating. This engraving defines a passage in which the fluids circulate.
- the document FR 2 950 960 A1 describes a solution for implementing a frame-shaped intermediate piece.
- This solution is not satisfactory because in the case where the plane of joint between the matrix and the intermediate part is orthogonal to the stacking of the matrix, a frame does not allow to take into account the dimensional variations of the matrix during the brazing, especially the sagging that results from the fusion and exudation of the solder. It is therefore necessary that the matrix is previously assembled in a first brazing step, that it is then machined to the shape of the frame, the latter being assembled to the matrix in a second brazing step.
- brazed matrix composed of a stack of etched plates or a stack of waves, separating plates and bars, or a combination of the two types of stack;
- an intermediate assembly for linking the dispensing head to the matrix; and characterized in that the intermediate assembly and the matrix are nested one inside the other by a male-female connection, preferably undercut, and brazed to one another.
- the intermediate assembly contributes to the positioning of the etched plates and / or the separation plates and bars during the stacking of the matrix and to their holding in position during brazing;
- the intermediate assembly is a separate set of the dispensing head which is fixed, and in particular welded, to the dispensing head;
- the intermediate assembly comprises two profiles, for example with a cross-section in the shape of an "L";
- the intermediate assembly extends longitudinally in a direction substantially orthogonal to the etched plates or separation sheets of the matrix.
- the method being characterized in that, before brazing, the intermediate assembly and the matrix are nested one inside the other, then the assembly constituted by the matrix and the intermediate assembly is frozen by soldering in a single operation .
- the manufacturing method according to the invention comprises one, several or all of the following characteristics, in all technically possible combinations:
- said nesting is carried out by stacking the etched plates and / or by stacking the waves of the separation plates and the bars of the matrix along the intermediate assembly;
- said nesting is carried out with a transverse clearance between the intermediate assembly and the etched plates and / or the separating plates and the bars of the matrix, this transverse clearance allowing vertical subsidence of the matrix during brazing;
- the invention is also based on the idea of using the intermediate assembly, serving to attach the fluid dispensing head to the matrix of the heat exchanger, also as a means of positioning and stabilization of the layers during the heating. stacking of the matrix and its collapse during brazing.
- the intermediate assembly then provides a dual function of connection between the matrix and a fluid distribution head and positioning and stabilization of the layers of the matrix.
- FIG. 1 is a diagrammatic representation in an exploded view of a matrix being stacked with an intermediate assembly comprising two intermediate parts, according to a first embodiment of the invention
- FIG. 3 is a schematic representation of the finalized exchanger according to the first exemplary embodiment of the invention illustrated in FIGS. 1 and 2, and
- Figure 4 is a schematic representation in exploded view of a matrix being stacked with a dispensing head, according to a second embodiment of the invention.
- FIG. 1 a stack of a die 2 is shown diagrammatically in the course of realization according to a first embodiment with an intermediate assembly with two intermediate pieces 7 with an L section.
- FIG. description is limited to the installation of a single distribution head, whereas an exchanger includes at least two and often more.
- the ends of the intermediate pieces 7 protrude from either side of the die 2 to receive on each side a plate 19 for closing the dispensing head (see Figure 2). This will be described in more detail later.
- a temporary plate 16 is first placed on the laying plane 1 1. The thickness of this plate 16 corresponds to the desired overshoot of the intermediate pieces 7.
- the intermediate pieces 7 serve as squaring system and facilitate and ensure the positioning of the successive layers of the die 2.
- the intermediate pieces 7 protrude from the upper side of the die.
- the matrix 2 of a length slightly smaller than the thickness of the temporary plate 16 so as to take into account the sagging of the matrix during brazing.
- the intermediate pieces 7 are maintained in vertical translation only by the laying plane 1 1 until the fusion of the solder.
- the successive layers of the stack of the die 2 are substantially parallel to the cross section 14 of the die 2.
- the intermediate pieces 7 extend longitudinally in a direction 15 substantially perpendicular to the cross-section 14 of matrix 2.
- the matrix 2 is placed on it a holding tool in compression, for example simply consisting of masses placed above the last plate of the stack.
- the holding tool ensures the vertical displacement of the layers of plates 3, waves 4 and bars 5, 6 of the matrix 2 which results from the collapse of the latter during the fusion of the solder, while maintaining a compressive force sufficient.
- the intermediate pieces 7 placed on the laying plane 1 1 have a fixed position during brazing.
- the plates 3 and bars 5, 6 slide along the intermediate parts 7 during the collapse of the matrix 2.
- the male-female nesting between the intermediate parts 7 and the plates 3 and the bars 5, 6 contributes to the maintenance of position of the matrix 2 during brazing.
- the invention similarly allows the etched plates to slide along the intermediate parts during the melting of the solder.
- the two intermediate parts 7 are profiles with an "L" cross section, the bases of the L being turned towards one another.
- the transverse clearance between the profile of the profiles 7 and the openings 8 must be sufficient to allow the assembly of the matrix 2 and the relative vertical displacement between the profiles 7 and the plates 3 and bars 5, 6 during brazing. This transverse clearance is for example between 0.1 and 0.4 mm.
- a solder tank in the form of a groove, is present along the interface between the male part of the sections 7 and the female parts, namely the openings 8 of the plates 3, 10, 20 and bars. 6.
- the existence of this reservoir ensures the presence of solder along the entire length of the contact surface between the intermediate parts 7 and the matrix 2.
- the composition of the solder is adapted for the state of the solder to prevent runoff.
- the successive layers of the die 2 are stacked in the traditional way, then the intermediate pieces 7 are slid in alignment with the openings 8 of the die 2.
- the intermediate pieces 7 serve as guides for stacking the die 2 as described above.
- FIG. 2 we can see diagrammatically represented the matrix 2 once the brazing operation performed. It can be seen in this figure that the intermediate pieces 7 protrude from both sides of the die.
- a dispensing head 17 of substantially semi-cylindrical shape is then attached to the die 2 by welding its end slices to those of its parallel branches of the intermediate pieces 7, which protrude laterally relative to the die. Terminal plates 18 and 19 are then attached to the dispensing head 17 to obstruct the ends of the dispensing head 17.
- FIG. 4 another embodiment of the invention in which the dispenser head 17 is extended by the intermediate parts 7 is shown schematically.
- the intermediate parts 7 are thus integral with the dispensing head 17. before the assembly of the matrix 2.
- the intermediate parts 7 may have been added to the distribution head 17, for example by welding, or be an integral part thereof.
- the dispensing head 17 can be made from a single piece comprising the shape of the intermediate pieces 7.
- the method of assembly of the matrix 2 is similar to that described above with reference to FIG.
- the assembly constituted by the die 2 and the dispensing head 17 is brazed in a single operation, directly in the brazing furnace.
- the dispensing head 17 For maintenance operations of the heat exchanger 1 that would require removing the dispensing head 17, for example for a catalyst change in the heat exchanger 1, it will cut the dispensing head 17. This cutting is performed at a line 13 corresponding to the weld joint if the dispensing head 17 and the intermediate parts 7 are welded, or for example a groove reducing the thickness of material to its place and thus facilitating cutting if the dispensing head 17 and the intermediate parts 7 are in one piece.
- the dispensing head 17 can be replaced by welding on the intermediate pieces 7 which remain integral with the die 2.
