Description
Echangeur de chaleur. La presente invention se rapporte ä, un. i'#chiinb, ur de chaleur destinA ä eire employz avec un moyen de ehauffage d'un liquide, cet echangeur comprenant une serie de tuyaux @lestines ä 1'ecoulement de ce liquide et 1?ourvus d'ailettes en metal, les ga.z chauds provenant de la chambre de combustion de vant passer par-des:sus et entre les ailettes de 1'echangeizr pour arri.ver ä, iui conduit de sortie. Heat exchanger. The present invention relates to, a. i'#chiinb, heat ur intended to be used with a means of heating a liquid, this exchanger comprising a series of pipes @lestines to the flow of this liquid and 1? ourvus of metal fins, the gas .z hot from the combustion chamber vant pass over: above and between the fins of 1'echangeizr to arri.ver ä, iui outlet conduit.
Dans les constru.ctions usuelles d'echan- geurs de chaleur de ce genre, le.s tuyaux rl'ecoulement out des sections transversales eirculaires et les nilettes presentent des trous d'un diametre approprie. Lors de Fassem- Wage de ces echangeurs, les tuyaux sont liousses ä travers ces trous et les ailettes sont: fixees par brasa.ge ou d'une autre ma- iiiere. Dans certains cas, toutefoi;s, il est pre- ferable de pratiquer des encoches Jans: les ailettes pour y loger les tuyaux d'ecoulement (in liquide. In the usual constructions of heat exchangers of this type, the pipes flow out of circular cross-sections and the fins have holes of an appropriate diameter. When assembling these exchangers, the pipes are passed through these holes and the fins are fixed by brazing or other material. In some cases, however, it is preferable to make Jans notches: the fins to accommodate the flow pipes (in liquid.
En pratiquant ces encoches, an enleve une certaine portion de la s.urface de chauf- fa.ge des ailettes, ce qui ne convient pas tou- joiirs. Cet iuconvenient est elimine, dans 1'eehangeur objet de 1'invention, en raison du fait qüe les encoches, dans lesquelles sont loges les tuyaux, present:ent, au moins sur leurs cötsss lateraux, des rebords formes par des parties redressees de 1'ailette. By making these notches, a certain portion of the heating surface of the fins is removed, which is not always suitable. This iuconvenient is eliminated, in the exchanger object of the invention, due to the fact that the notches, in which the pipes are housed, present: ent, at least on their lateral cötsss, edges formed by straightened parts of 1 'fin.
Le dessin annexe represente, ä titre d'exemples, deux formes d'execution de 1'ob- jO: de 1'invention. La fig. 1 est une vue en perspective et la fig. 2 une vue en plan d'un ass.emblage de tuyaux .ä, liquide et d'ailettes d'un echan- geur de chaleur suivant 1a premiere forme d'exAcution. The accompanying drawing shows, by way of example, two embodiments of the object of the invention. fig. 1 is a perspective view and FIG. 2 is a plan view of an assembly of liquid pipes and fins of a heat exchanger according to the first embodiment.
La fig. 3 est une vue en elevation, et la fig. 4 est une vue frontale d'un 6chan- geur de chaleur suivant 1a deuxieme forme d'execution. fig. 3 is an elevational view, and FIG. 4 is a front view of a heat exchanger according to the second embodiment.
L'echangeur de chaleur suivant les fig. 1 et 2 eomprend deux tuyaux 5, destines 1'ecoulement d'un liquide, presentant une section transversale eirculaire et pourvus dune serie d'ailettes metalliques. encochees 6, fixees sur eux. Chaque ailette 6 presente deux encoches en forme d'U, destinees ä ser- vir de logement pour les tuyaux 5. Chaque encoche est formee en pratiquant une ferste dans f'ailette et en redressant la partie de mkal situee autour de cette ferste, de fagon ä obtenir un rebord marginal 7. The heat exchanger according to Figs. 1 and 2 comprise two pipes 5, intended for the flow of a liquid, having a circular cross-section and provided with a series of metal fins. notches 6, fixed on them. Each fin 6 has two U-shaped notches, intended to serve as housing for the pipes 5. Each notch is formed by making a cut in the fin and straightening the part of metal located around this way to obtain a marginal edge 7.
Les fig. 3 et 4 montrent un echangeur de chaleur presentant des tuyaux aplatis 8 et pourvus RTI ID="0001.0271" WI="14" HE="4" LX="1198" LY="1830"> d'ailettes 9 en metal. Chaque ailette presente deux encoches oblongues, dann les- quel'les sont loges les tuyaux 8, chacune de ces encoches etant formee en fendant les ailettes et en redressant les parties de metal situees des deux cötes de chaque ferste, de fagon ä produire des. rebords lateraux 10. Figs. 3 and 4 show a heat exchanger having flattened pipes 8 and provided RTI ID="0001.0271" WI="14" HE="4" LX="1198" LY="1830"> fins 9 in metal. Each fin has two oblong notches, in which the pipes 8 are housed, each of these notches being formed by splitting the fins and straightening the metal parts located on both sides of each ferst, so as to produce. side edges 10.
Les encoches ä rebords tell.es que prevues dans les deux exemples representes ont f'avantage qu'elles presentent une grande surface pour leur fixation aux tuyaux d'ecoulement, fixaton qui peut Acre effectuee pax soudage, brasage ou d'une autre ma- ni6re; en. outre, les rebords des ailettes cons- tituent en meme temps des moyens d'espace- ment pour mainteniT les . ailettes ä des dis- tances determinees Tune par rapport ä 1'autre. The flanged notches as provided in the two examples shown have the advantage that they present a large area for their attachment to the drain pipes, which attachment can be effected by welding, brazing or other material. n6re; in. Furthermore, the edges of the fins constitute at the same time spacing means for maintaining them. fins at determined distances from each other.
