Definitions

  • the invention relates to a heat exchanger with tubes that are adjacent to one another, preferably arranged parallel to one another, connected to one another via end-side deflections and flow through one another in opposite directions, the deflections having an outer wall forming a hood covering the end sides of adjacent tubes.
  • the object of the invention is to design the deflections as fluidly as possible as cheaply, and in such a way that their manufacture can be carried out inexpensively and with little expenditure of time and effort.
  • Both walls namely the outer wall forming the hood and / or the inner wall, can be formed, preferably pulled, from sheet metal in a very solid and with sufficient rigidity.
  • these walls can be connected to one another at the edges, for example by a circumferential fold, but also by welding, soldering, gluing or the like.
  • the outer wall forming the hood can be shaped in at least one of its two end regions to form a connecting piece suitable for connecting such a power.
  • this connecting piece is coaxially opposite an end face of one of the tubes of the heat exchanger, so that the flow of a medium flowing in via the connecting piece continues as far as possible in the tubes of the heat exchanger or the flow of the medium emerging from these tubes - likewise without interference - can get into a discharge line.
  • Such a connecting piece can advantageously be designed within the scope of the invention with an oval, in particular elliptical cross-section, the longer axis of which corresponds approximately to the parallel dimension of the part of the outer wall that forms the hood, bulges and encloses a cavity.
  • the sheet metal forming the outer wall can be used in the best possible way for efficient management of the medium used for heat exchange.
  • the connecting piece with a circumferential shoulder can be designed to taper outwards.
  • the illustrations first show the outer wall 1, which is designed as a hood 9, covering the end faces of the two tubes 5 of the heat exchanger to be connected, and the inner wall 2, which extends over these end faces and is penetrated by the cavities 6 of these tubes 5 and bridges the distance between the tubes 5 the connecting piece 3 serving to connect the pipes 5.
  • the inner wall 2 in its regions bridging the distances between the tubes 5 and serving to redirect the heat-exchanging medium carried in these tubes 5, has a concave cross section with a curvature directed against these connecting pieces 3.
  • Both walls ie the outer wall 1 forming the hood 9 and the inner wall 2, can be made of sheet metal, preferably drawn.
  • the outer wall 1 of the deflection can be connected to the inner wall 2 in a flat and sealing manner by means of a fold 4 running all around on the edge, or also by welding, soldering or gluing.
  • the arrangement and shape of the two walls 1 and 2 result in a fluidically very favorable profile for the medium circulating and to be deflected in the cavities 6 of the tubes 5 of the heat exchanger, for example water to be heated.
  • the outer wall 1 of the deflection can extend over the mouths of a group of parallel tubes 5, of which only three tubes 5 are shown, the tube 5 shown on the right in FIG. 3 being the first (or last) is this coulter and is to be connected to a supply or discharge line for the medium flowing through the pipe coulter and is not changed in diameter, in contrast to the embodiment according to FIG. 1, in which the pipe has been expanded.
  • This connecting piece 7 is coaxially opposite to an end face of this (first or last) tube 5, so that the flow of a medium flowing through the tube 5 continues smoothly into the connecting piece 7 and the line 8 (or vice versa from the line 8 into the connecting piece 7 and the pipe 5 continues).
  • the connecting piece 7 can advantageously be designed within the scope of the invention with an elliptical cross section, the longer axis of which corresponds approximately to the parallel dimension a of the hood 9-forming, enclosing a region of the outer wall 1, so that the latter Outer wall 1 forming, deformed sheet metal blank is particularly efficiently used in this way for the deflection of the medium.
  • this connecting piece 7 is profiled according to FIG. 3 with an inwardly directed shoulder 10, which tapers it outwards.

Claims (7)

  1. Echangeur de chaleur constitué par des tubes (5) voisins les uns des autres et de préférence parallèles entre eux, reliés entre eux par des coudes disposés à leurs extrémités, tubes où circule un fluide dont la direction d'écoulement alterne d'un tube à l'autre, les coudes présentant une paroi extérieure (1) en forme de chape (9) recouvrant les bouts de tubes (5) voisins, caractérisé par le fait que les coudes comportent une paroi intérieure (2) s'étendant sur les faces frontales, paroi munie de tubulures (3) pour le raccordement des tubes (5) et présentant dans sa partie recouvrant la distance entre ces tubulures de raccordement (3) un profil concave orienté vers ces tubulures (3).
  2. Echangeur de chaleur suivant la revendication 1, caractérisé par le fait que la paroi extérieure (1) formant la chape (9) et/ou la paroi intérieure (2) sont faites de tôles profilées, de préférence embouties.

  4. Echangeur de chaleur suivant l'une des revendications 1 à 3, caractérisé par le fait que, pour le branchement d'une conduite (8) assurant l'adduction ou l'évacuation du fluide circulant dans les tubes (5), la paroi extérieure (1) formant la chape (9) comporte au moins à l'une de ses extrémités une tubulure (7) pour le raccordement de cette conduite.
  5. Echangeur de chaleur suivant la revendication 4, caractérisé par le fait que cette tubulure (7) est disposée coaxialement en face du bout de l'un des tubes (5).
  6. Echangeur de chaleur suivant la revendication 4 ou 5, caractérisé par le fait que la tubulure (7) a une section ovale, notamment elliptique, dont le grand axe correspond à peu près à l'étendue (a), parallèle à cet axe, de la partie de la paroi extérieure (1), formant la chape (9) emboutie et renfermant un creux.
  7. Echangeur de chaleur suivant l'une des revendications 4 et 6, caractérisé par le fait que la tubulure (7) est munie d'un épaulement circonférentiel (10) en rétrécissement de la section de sa partie extérieure.
