WärmetauscherHeat exchanger
Die vorliegende Erfindung "bezieht sich auf einen Kreuzstrom-Wärmetauscher, dessen, dem Wärmeaustausch dienenden Flächen aus verformbaren Platten "bestehen, die aufeinandergelegt abwechselnd miteinander so verbunden sind, daß sich zwischen den Platten Kanäle "bilden, durch die die in Wärmeaustausch tretenden Fluide im Kreuzstrom zueinander strömen.The present invention "relates to a cross-flow heat exchanger, its, the heat exchange serving surfaces consist of deformable plates "which are placed on top of one another are alternately connected to one another so that channels "are formed between the plates through which the fluids entering into heat exchange in cross-flow flow towards each other.
Es ist "bereits bekannt, Wärmetauscher herzustellen, deren dem Wärmeaustausch dienende Flächen aus verformbaren Platten bestehen, die aufeinandergelegt miteinander so verbunden werden, daß sich zwischen den Platten Kanäle bilden, durch die die in Wärmeaustausch tretenden Fluide strömen können. Diese Platten werden entweder durch Zwischenstücke oder dadurch auf Abstand gehalten, daß sie zumindest teilweise, beispielsweise durch Eindrucken an bestimmten Stellen oder durch sonstige geeignete geometrische Formgebung selbst als Abstandstücke wirken.It is "already known to manufacture heat exchangers whose the heat exchange serving surfaces consist of deformable plates, which are placed on top of each other be connected in such a way that channels are formed between the plates through which the heat exchange occurs Fluids can flow. These plates are held at a distance either by spacers or by this, that they are at least partially, for example by imprinting in certain places or by other suitable geometric shape itself act as spacers.
Es ist auch schon bekannt, Kunststoffe zur Herstellung von Wärmetauschern zu verwenden· Bei der Verwendung solcher Werkstoffe, die ein geringes Wärmeleitvermögen haben, ist man bestrebt, die Wandstärke möglichst gering zuIt is also already known to use plastics for the production of heat exchangers · When using such For materials that have a low thermal conductivity, efforts are made to keep the wall thickness as small as possible

halten, weil man nur dadurch preiswerte Wärmetauscher mit vergleichsweise kleinen Wärmeaustauschflächen herstellen kann.because this is the only way to produce inexpensive heat exchangers with comparatively small heat exchange surfaces can.
Wenn zwischen den in Wärmeaustausch miteinander stehenden Fluiden größere Druckdifferenzen bestehen, so kann man Rohrbünde !-Wärmetauscher einsetzen, deren Heizrohre einen kleinen Durchmesser haben. Die Fertigung solcher Rohrbündel-Wärmetauscher ist aber wegen der dabei benötigten Rohrplatten schwierig.If between the standing in heat exchange with each other If there are larger pressure differences in fluids, you can use tube bundles! have a small diameter. The production of such tube bundle heat exchangers is required because of the Tube plates difficult.
Für solche Fälle, in denen zwischen den wärmetauschenden Fluiden keine oder nur geringe Druckunterschiede bestehen, lassen sich besser Wärmetauscher verwenden, deren Wärmeaustauschflächen plattenförmig sind. Wegen des schlechten Wärmeleitvermögens hat man für solche Platten-Wärmetauscher bisher Kunststoff als Werkstoff nicht benutzen können.For those cases where between the heat exchangers If there are no or only slight pressure differences in fluids, it is better to use heat exchangers whose Heat exchange surfaces are plate-shaped. Because of the poor thermal conductivity, plate heat exchangers are used for such so far have not been able to use plastic as a material.
Die vorliegende Erfindung zeigt nun einen Weg, um auch Kunststoffe als Werkstoffe für Platten-Wärmetauscher in einfacher Weise einzusetzen. Sie schlägt vor, einen Wärmetauscher aus dünnen verformbaren Kunststoffflächen herzustellen, die aufeinander gelegt werden und abwechselnd in Längs- bzw· Querrichtung miteinander derart verbunden werden, daß zwischen ihnen Kanäle entstehen, durch die die in Wärmeaustausch tretenden Fluide strömen können.The present invention now shows a way to also Plastics as materials for plate heat exchangers in easy way to use. She suggests a heat exchanger made from thin, deformable plastic surfaces produce, which are placed on top of each other and alternately in the longitudinal or transverse direction with each other in such a way are connected so that channels are formed between them through which the fluids entering heat exchange flow can.
Vorzugsweise werden zur Herstellung eines Wärmetauschers nach der Erfindung Folien aus Kunststoff benutzt, und es werden jeweils benachbarte Folien durch eine in gleich-Preferably used to manufacture a heat exchanger according to the invention films made of plastic used, and there are in each case adjacent films by an in the same-

mäßigen Abständen durchgeführte Punktschweißung miteinander verbunden. Solche Schweißungen lassen sich verhältnismäßig einfach mit beheizten Stempeln oder bzw. auch mit Ultraschall-Sonotroden durchführen. Zur Verbindung der als Wärmeaustauschflächen dienenden Folien aus geeignetem Kunststoff kommen aber auch geeignete Klebeverbindungen in Frage.spot welds carried out at moderate intervals tied together. Such welds can be relatively easy with heated punches or or also with ultrasonic sonotrodes. To the However, there are also suitable connections between the foils made of suitable plastic and used as heat exchange surfaces Adhesive connections in question.

Der in Fig. 1 dargestellte Wärmetauscher besteht aus den Folien 1, 2, 3 und 4, die jeweils gleiche Abstände zueinander haben. Diese Folien sind aber durch die in regelmäßigen Abständen durchgeführten PunktschweiBungen miteinander verbunden, und zwar verbinden die Schweißpunkte 5 die Folien 1 und 2, während die Schweißpunkte 6 die Folie 1 mit einer nicht dargestellten, darüberliegenden Folie verbindet.The heat exchanger shown in Fig. 1 consists of foils 1, 2, 3 and 4, which are each equally spaced from one another to have. These foils are, however, connected to one another by spot welds carried out at regular intervals connected, namely the welding points 5 connect the foils 1 and 2, while the welding points 6 the Film 1 connects to an overlying film, not shown.
Bei dem in Fig. 2 dargestellten Wärmetauscher sind jeweils zwei Polien an ihren Außenkanten durch EoIlschweißnähte 7 in der Weise miteinander verbunden, daß zueinander rechtwinklig verlaufende Strömungskanäle 8In the case of the heat exchanger shown in FIG. 2, two poles are in each case on their outer edges by means of oil-welded seams 7 connected to one another in such a way that flow channels 8

und 9 gebildet werden, die jeweils nur durch eine Folie voneinander getrennt sind. Mittels Eckstücken 10 (Fig. 3), die vorzugsweise aus gleichen oder ähnlichen Materalien wie die Folien, z.B. im Spritzgußverfahren, aus Kunststoff hergestellt werden können, läßt sich ein vollständiger Wärmetauscher herstellen. Durch die Verwendung gleichen Werkstoffes für Folien und Eckstücke wird eine gute Schweiß- bzw. Klebbarkeit gewährleistet. and 9 are formed, each of which is only separated from one another by a film. Using corner pieces 10 (Fig. 3), which are preferably made of the same or similar materials as the foils, e.g. in the injection molding process, can be made from plastic, a complete heat exchanger can be made. Through the Use of the same material for foils and corner pieces ensures good weldability and adhesion.
Die Eckstücke 10 haben nicht nur die Aufgabe, die Folien in gleichmäßigem Abstand zu halten, sie verhindern auch eine Vermischung der im Wärmeaustausch miteinander stehenden Fluide an den Ecken des aus den einzelnen Folien gebildeten Folienpaketes.The corner pieces 10 not only have the task of keeping the foils evenly spaced, they prevent them also a mixing of the heat exchanges with each other standing fluids at the corners of the foil package formed from the individual foils.
Bei dem in Fig. 4 dargestellten Wärmetauscher treten die beiden Fluide über Stutzen 11 in Verteilerräume 12 ein. Sie durchströmen das Folienpaket im Kreuzstrom und sammeln sich danach in Sammelräumen 13, aus denen sie über Stutzen 14 den Wärmetauscher verlassen. P Mit 15 sind die Begrenzungswände des Wärmetauschers bezeichnet.In the heat exchanger shown in FIG. 4, the two fluids pass through nozzles 11 into distribution spaces 12 a. They flow through the foil package in a cross flow and then collect in collecting spaces 13 which they leave the heat exchanger via nozzle 14. P With 15 are the boundary walls of the heat exchanger designated.
