Definitions

  • the present invention relates to heat exchangers and more particularly heat exchangers used as coolers, for example as cooling radiators of a heat engine.
  • the invention relates more particularly to the exchangers used on heavy goods vehicles whose end tubes are subjected to significant stresses both thermal and mechanical, which requires strengthening the connection tubes-collector plates.
  • DE-C-703 758 describes a corrugated header plate whose tube passages have bevelled parts and a heel resting on a development of the tubes engaged in the tube passages.
  • the corrugated part of the collector plate forms retained by the solder which also extends between each opening and the underside of the collector plate.
  • the arrangement recommended by the previous publication requires a precise shaping of the collector plate and the realization of a development on each tube, which constitutes an operation which can be carried out essentially with tubes of circular section.
  • the invention simplifies the known embodiments by taking advantage of a drawback presented by the collector plates in which the tube passages are formed by cutting and bending the collars.
  • the method for reinforcing by means of plates at least rows of tube ends, engaged in header plates to form a heat exchanger in which the tube passages of the header plate are made by punching of the collector plate to delimit bevelled parts is characterized in that, in a manner known per se, cambered collars so that the bevelled part is located at the upper end of the collets, in that the bottom of the parts of the collector plate separating two passages of successive tubes so that it is curved, in that the curved parts are applied against a flat plate pierced with lights corresponding to the tubes, this plate being placed on the tubes before the collector plate and in that the assembly is brazed after fluxing, the spaces delimited between the convex parts of the collector and planes of the plate forming circulating circuits ca pills for soldering causing elimination of the flux.
  • Fig. 1 is a plan seen from above of a collector plate of a heat exchanger with circulation tubes comprising the reinforcement device of the invention.
  • Fig. 2 is a very enlarged sectional elevation seen along line II-II of FIG. 1.
  • the drawing illustrates a rectangular collecting plate 1 which delimits tube passages 2 for tubes 3.
  • the collecting plate 1, which is metallic, is shaped by punching so that the tube passages 2 are delimited by collars 4 with bevelled end 4a.
  • the tubes 3 are engaged in the collars 4 and their upper end is flared as shown in 3a above the bevelled part 4a.
  • This embodiment of the collector plate has the additional effect that the bottom 5 of the spaces separating the collars is not planar but, on the contrary, curved as illustrated in FIG. 2, the decreasing radius of curvature in the vicinity of the part joining the bottom 5 to the side of the collars 4 as illustrated in 5a.
  • plates 6 are used which extend over a few rows of tubes, for example four as shown.
  • the plates 6 are completely flat and in their thickness, by means of cutting tools, lights 7 whose shape corresponds to that of the tubes and whose dimensions are slightly larger than those of the tubes 3.
  • the plates 6 are placed so that they are in contact with the underside of the collecting plate, that is to say with the underside of the convex part 5.
  • This arrangement has the effect of providing space between the collecting plate and the above each wafer capillary spaces 8 which communicate with capil spaces laires 9 formed between the openings 7 of the wafer 6 and the outer wall of the tubes 3.
  • the assembly produced is brazed, for example a soft brazing at by means of a lead tin alloy or the like which diffuses into the capillary spaces described above, none of which has dimensions such that residual flows can be retained.
  • the solder since all the spaces are capillary, the solder, when it melts, necessarily circulates in all the parts of the spaces and consequently repels the flux which could be there to allow the wetting of the metal by the solder.

1. Verfahren zur Verstärkung mittels Platten (6) von insbesondere Reihen von Rohrenden (3), die in Sammelplatten (1) gefaßt sind, zur Herstellung eines Wärmetauschers, in welchem die in der Sammelplatte (1) für die Rohre (2) ausgesparten Durchtrittsöffnungen durch Ausstanzen der Sammelplatte zur Begrenzung von abgeschrägten Teilen ausgeführt werden, dadurch gekennzeichnet, daß die Kragen (4) auf eine an sich bekannte Weise gebogen werden, damit sich der abgeschrägte Teil (4a) am oberen Ende der Kragen befindet, daß der Boden (5) der Bereiche der Sammelplatte, welche aufeinanderfolgende Durchtritte von Rohren (2) trennen, verformt wird, damit er gewölbt ist, daß ferner auf dem gewölbten Abschnitt (5) eine ebene Platte (6) aufgebracht wird, welche Durchtrittsöffnungen (7) aufweist, die den Rohren (3) entsprechen, wobei diese Platte auf die Rohre aufgebracht wird, bevor die Sammelplatte (1) aufgebracht wird, und daß die Anordnung nach Flüssigmachen gelötet wird, wobei die zwischen den gewölbten Bodenreichen und den Ebenen der Platte gebildeten Zwischenräume kapillare Umwälzkreisläufe für das Lot darstellen, die eine Ausscheidung des Flußmittels herbeiführen.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das Ende der Rohre oberhalb der abgeschrägten Teile der Kragen aufgeweitet ist, um ebenfalls die Umwälzung des Lots und das Zurückhalten desselben zu gewährleisten.
3. Verfahren nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, daß die in der Platte angebrachten Durchtrittsöffnungen eine Formgebung entsprechend jener der Rohre aufweisen, jedoch gegenüber den äußeren Abmessungen derselben eine geringfügig größere Abmessung aufweisen.
4. Verfahren nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Lötung erfolgt, während der gewölbte Boden jener Teile der Sammelplatte, welcher die Durchtritte der Rohre voneinander trennt, oberhalb der Ebene der Platte (6) angeordnet ist.
5. Verfahren nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß mehrere Platten einer gemeinsamen Sammelplatte zugeordnet sind.
6. Verfahren nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß eine Platte die gesamte Erstreckung einer Sammelplatte abdeckt.
7. Verwendung des Verfahrens nach einem der Ansprüche 1 bis 6 zur Herstellung eines Wärmetauschers als Kühler für Fahrzeuge, insbesondere Schwerlastfahrzeuge.
