Description

Die Erfindung bezieht .sich auf Wärmeaustauscher, die aus einzelnen im wesentlichen gleichgeformten Blechpreßstücken ,zusammengesetzt sind und durch deren gegabelte Enden Kanäle gebildet werden, nach Patent 854 363.The invention relates .sich to heat exchangers that consist of individual substantially identically shaped sheet metal pressings, are assembled and by whose bifurcated ends are formed into channels, according to patent 854 363.

Um einen möglichst großen Wärmeaustausch zu erhalten und um Wirbelbildungen der wärmeaustauschenden Mittel in den Zu- und Ableitungen zu vermeiden, sind in einem Wärmeaustauscher nach Patent 854 363 gemäß der Erfindung in jedem der Kanäle den Strom des Mittels unterteilende und diesen führende Stege befestigt. Die Stege sind parallel zueinander angeordnet und reichen bis zu den den eigentlichen Wärmeaustauscher bildenden Blechwellen. - Dadurch wird die zur Verfügung stehende Wärmeaus.tauschfläche vergrößert.In order to obtain the greatest possible heat exchange and to avoid vortex formation of the heat exchanging agents in the supply and discharge lines are to be avoided in a heat exchanger according to patent 854 363 according to the invention in each of the channels the flow of the agent dividing and attached to this leading webs. The bridges are arranged parallel to each other and extend to the actual heat exchanger forming sheet metal waves. - This increases the available heat exchange area enlarged.

In der Zeichnung, welche eine beispielsweise Ausführung der Erfindung zeigt, ist .In the drawing, which shows an example embodiment of the invention shows is.

Fig. i ein Schaubild eines der Blechpreßstücke eines Wärmeaustauschers gemäß der Erfindung und Fig.2 eine Endansicht der gegabelten Enden von vier zusammengebauten Blechpreßstücken des Wärmeaustauschers.Fig. I is a diagram of one of the sheet metal pressings of a heat exchanger according to the invention and Figure 2 is an end view of the forked ends of four assembled Pressed sheet metal parts of the heat exchanger.

Der Wärmeaustauscher besteht aus einzelnen, im wesentlichen gleichgeformten Blechpreßstücken i, die übereinandergestülpt und miteinander befestigt sind. Jedes der Blechpreßstücke enthält einen mittleren flachen Teil mit längs gerichteten Wellen 2. Die Enden .der Blechpreßstüo'ke sind gegabelt, und die Wände 3 und 4 sowie 5@ und 6 sind abgewinkelt, wodurch einseitig offene Rinnen-7,. 9 und Kanäle 8, io gebildet werden. Die Seitenwände der Kanäle 8, io sind höher als die der Rinnen 7, 9. Die Kanäle jedes der Bleckpreßstücke sind durch senkrechte Blechstege ii unterteilt, wodurch der Strom der Mittel in mehrere Teilströme unterteilt wird. Die Stege i i sind entsprechend den seitlichen Außenwänden 4 und 5 der Kanäle gebogen. Sie reichen vom Ende des Kanals, -d. h. von der Stelle, wo der Eintritt der-Mittel in den Wärmeaustauscher erfolgt, bis zu den Blechwellen, welche den eigentlichen Wärmeaustauschlkörper bilden. Sie sind vorzugsweise parallel zueinander angeordnet und durch Schweißen, Hartlöten od. dgl. in den Kanälen befestigt.The heat exchanger consists of individual, essentially identically shaped Pressed sheet metal pieces i, which are placed one on top of the other and fastened to one another. Each the sheet metal pressings include a central flat portion with longitudinally directed undulations 2. The ends of the Blechpreßstüo'ke are forked, and the walls 3 and 4 and 5 @ and 6 are angled, whereby gutters 7, open on one side,. 9 and channels 8, io formed will. The side walls of the channels 8, io are higher than those of the channels 7, 9. The Channels of each of the pressed sheet metal pieces are divided by vertical sheet metal webs ii, whereby the flow of the means is divided into several partial flows. The webs i i are bent according to the lateral outer walls 4 and 5 of the channels. You are enough from the end of the channel, -d. H. from the point where the entry of the agent into the heat exchanger takes place, up to the sheet metal shafts, which form the actual heat exchange body. They are preferably arranged parallel to one another and by welding, brazing Od. Like. Fixed in the channels.

Dadurch wird nicht nur ein störungsfreier Fluß der Mittel durch den Wärmeaustauscher begünstigt, sondern auch die nutzbare Fläche desselben und damit dessen Wirksamkeit bedeutend vergrößert.This not only ensures a smooth flow of funds through the Heat exchanger favors, but also the usable area of the same and thus its effectiveness significantly increased.

Die Stege sind vorzugsweise sowohl in den die Mittel zuführenden als auch in den die Mittel ableitenden Kanälen angeordnet. Die Anzahl der Stege richtet sich nach den. jeweiligen Erfordernissen.The webs are preferably both in the means supplying as also arranged in the channels draining the means. The number of webs aligns after the. respective requirements.
