Claims (1)

<Desc/Clms Page number 1> <Desc / Clms Page number 1> La présente invention a pour objet un échangeur de chaleur en tôle d'acier, assurant une utilisation maxima du poids de métal, une exécution simple et un encombrement réduit. The present invention relates to a heat exchanger made of sheet steel, ensuring maximum use of the weight of metal, simple execution and reduced bulk. La figure 1, représente le principe de l'invention. La surface de séparation des deux fluides - chaud et froid - est constituée par une tôle d'acier. Afin d'augmenter cette surface, des ailettes en forme de "U" sont soudés électriquement, de préférence par points (sans métal d'ap- port). FIG. 1 represents the principle of the invention. The separation surface of the two fluids - hot and cold - is formed by a sheet of steel. In order to increase this surface area, "U" shaped fins are electrically welded, preferably spot-welded (without load metal). La base des "U" est ainsi parfaitement appliquée contre la surfa- ce et la transmission de chaleur dans les branches est assurée. The base of the "U" is thus perfectly applied against the surface and the heat transmission in the branches is ensured. La transmission de chaleur est facilitée en même temps que la çons- truction par le fait que les "U" sont placés en opposition directe. The heat transfer is facilitated at the same time as the construction by the fact that the "U" are placed in direct opposition. Dans le but d'augmenter la transmission de chaleur, les branches des "U" peuvent être traitées de façon à assurer une turbulence accrue. In order to increase heat transmission, the "U" branches can be treated to provide increased turbulence. A titre d'exemple non limitatif, nous citons ci dessous quelques variantes Une façon simple de traiter les "U" est de les entailler plier ou tordre à intervalles réguliers ou non réguliers comme fig. 2 et 3. By way of non-limiting example, we cite some variants below. A simple way to deal with "U's" is to notch, bend or twist at regular or irregular intervals like fig. 2 and 3. Une autre variante serait d'emboutir des ondulations. Another variation would be to stamp waves. REVENDICATIONS. CLAIMS. 1 Un échangeur de chaleur en tôle, constitué par des profils en forme de "U", soudés sur une tôle de séparation. 1 A sheet metal heat exchanger, made up of U-shaped profiles, welded to a separating sheet. 2 Un échangeur suivant revendication 1 , caractérisé par ce que les branches en "U" sony traitées, entaillées ou embouties de façon à as- surer une turbulence accrue et par conséquent, un meilleur coefficient de transmission de chaleur. **ATTENTION** fin du champ CLMS peut contenir debut de DESC **. 2 An exchanger according to claim 1, characterized in that the "U" -shaped branches are treated, notched or stamped so as to ensure increased turbulence and therefore a better heat transfer coefficient. ** CAUTION ** end of field CLMS may contain start of DESC **.
