  ECHANGEUR DE CHALEUR A TUBES. 



   Les échangeurs de chaleur à tubes;, servant à   transmettre   de la chaleur d'un milieu à plus haute température à un milieu distinct à plus bas- se températurepar exemple dans les   condenseurs.,   les réchauffeurs   d'air   ou d'eau, les appareils réfrigérants pour   lhuile   ou d'autres liquides, compor- tent un faisceau de tubes à parois minces dont les extrémités sont montées dans des trous de plaques tubulaires.

   Ces points de montage demandent une at- tention spéciale aussi bien en ce qui concerne la construction que la   fa-   brication parce qu'il est nécessaire d'avoir, en ces points, une étanchéité parfaite et   durable;,   en tenant compte cependant des différences de dilata- tion thermique des tubes et de 1-'enveloppe de l'échangeur de chaleur, 
La présente invention a pour but de permettre aux tubes de se dilater de façon quelconque sans qu'il s'exerce un effort quelconque, ni sur les tubes, ni sur les plaques tubulaires. 



   Ce résultat est obtenuselon l'invention, grâce à ce que, sur au moins 'une partie de la totalité du faisceau tubulaire, chaque tube comporte, à au moins une extrémité, une pièce de dilatation. Cette pièce de dilatation, facilement déformable élastiquement, est montée, de façon avantageuse entre le tube et la plaque et elle permet ainsi au tube de se dilater en longueur sans en être   empêché   par la plaque tubulaire fixe. 



   On a représenté trois exemples de réalisation de l'invention sur le dessin annexé. 



   Sur la figure 1, on voit une partie d'une plaque tubulaire   1   avec ouverture 2 dans laquelle est placée une pièce de dilatation   3,   fixée à   -on   tube 4 du faisceau, de tubes. Cette pièce 3 consiste en un tronçon de tube dé- formable, comme cela est déjà bien connu dans la technique., La pièce 3 est fixée sur la plaque tubulaire 1, d'une part,et sur le tube   4,   d'autre   part.,   par   soudure...

  TUBE HEAT EXCHANGER.



   Tube heat exchangers ;, used to transfer heat from a higher temperature medium to a separate lower temperature medium, for example in condensers, air or water heaters, appliances coolants for oil or other liquids, have a bundle of thin-walled tubes, the ends of which are mounted in holes in tube sheets.

   These mounting points require special attention both in terms of construction and fabrication because it is necessary to have, at these points, a perfect and lasting seal ;, taking into account however the differences thermal expansion of the tubes and of the heat exchanger shell,
The object of the present invention is to allow the tubes to expand in any way without exerting any force whatsoever, neither on the tubes nor on the tube sheets.



   This result is obtained according to the invention, thanks to the fact that, over at least part of the entire tube bundle, each tube comprises, at least one end, an expansion part. This expansion piece, easily elastically deformable, is mounted, advantageously between the tube and the plate, and it thus allows the tube to expand in length without being prevented by the fixed tube plate.



   Three exemplary embodiments of the invention have been shown in the accompanying drawing.



   In Figure 1, we see a part of a tube plate 1 with opening 2 in which is placed an expansion part 3, fixed to -on tube 4 of the bundle, of tubes. This part 3 consists of a section of deformable tube, as is already well known in the art., Part 3 is fixed to the tube plate 1, on the one hand, and to the tube 4, on the other hand. ., by welding ...

   At the other end of the expansion piece 3, the tube 4 is de laDgi by expansion and it is tightened securely ;, with the part 3, in the ring 6G During the dudceomwge, the. ring 6 expands elastically under the action of the forces acting on it, so that at the end of the expansion, it contracts again and then exerts a permanent contraction force on the tube 4.



   The fixed connection of the tube 4, of the expansion piece 3 and of the ring 6 can also be achieved by heating the ring 6 before its assembly.

 and thereby causing hot irett-age.



  In the example of iéalisz-tion of Figure 3 the end of the tube 4 itself has the shape of an expansion piece by working it for this purpose.



  The connection with the tube plate 1 can in this case be made by welding
