Abstract

The surface heat exchanger is used as a component of a heat store. There are two flow surfaces or flow channels each of which has a feed and return connection (3,4 and 5,6). The feed- and return connections of the top flow surface and these of the bottom flow surface are connected to separate heating or cooling circuits. The fluid is constrained to follow a serpentine path through each heat exchanger element. The elements may be stacked together to make a compact structure.

Die Erfindung betrifft einen flachen Wärmetauscher nach dem Oberbegriff des Patentanspruches.The invention relates to a flat heat exchanger according to the preamble of the claim.

Ein Wärmetauscher dieser Art und seine Verwendung zum Aufbau eines,Wärmespeichers ist in der Europäischen Patentanmeldung Nr. 79 100 157.1 Yeröffentlichungsnummer 0 003 332 A1 beschrieben. Danach kann das Wärmespeichermedium in gasdichten Folienbehältern eingeschlossen sein, die auf den vom Wärmeträger durchströmten Druckbehälter eng anliegend aufgelegt werden und durch kissenartiges Anschmiegen den Wärmeaustausch begünstigen. Der flache Wärmetauscher kann danach auch aus zwei Druckbehältern in Übereinander- bzw. Ineinanderbauweise bestehen, wodurch sich der Vorteil eines Zweikreissystems ergibt. Die Bauweise eines solchen Wärmetauschers mit zwei in gleicher Ebene verlaufenden Strömungskanälen ist in der Deutschen Patentanmeldung Air. P 29 42 147 beschrieben.A heat exchanger of this type and its use for the construction of a heat accumulator is described in the European patent application No. 79 100 157.1 Publication No. 0 003 332 A1. Thereafter, the heat storage medium can be enclosed in gas-tight foil containers that are placed on the heat transfer medium through which the pressure vessel flows through, are placed tightly and the heat exchange is achieved through cushion-like nestling favor. The flat heat exchanger can then also consist of two pressure vessels built one above the other or one inside the other exist, resulting in the advantage of a two-circuit system. The construction of such a heat exchanger with two Flow channels running in the same plane are described in German patent application Air. P 29 42 147.

Gegenstand der Erfindung ist ein Wärmetauscher, in dem sich zwei übereinander angeordnete Strömungskanäle oder Strömungsflächen befinden. Der Vorteil gegenüber nebeneinander angeordneten Strömungskanälen besteht darin, daß fast die gesamte Tauscherfläche beidseitig von je einem Wärmeträger durchströmt wird. Daraus ergibt sich einmal eine gleichmäßige Wärmeverteilung über die Fläche, zum anderen findet ein sehr guter Wärmeaustausch zwischen den beiden Kreisläufen statt. Dies ist insbesondere dann von Vorteil, wenn Wärmeanfall und Wärmeentnahme zeitgleich sind. Entsprechendes gilt für den Einsatz eines Wärmespeichers zu Kühlzwecken.The invention is a heat exchanger in which two flow channels or flow surfaces arranged one above the other are located. The advantage over those arranged next to each other Flow channels consists in that almost the entire exchanger surface flows through a heat transfer medium on both sides will. This results in an even distribution of heat Over the surface, on the other hand, there is very good heat exchange between the two circuits. this is particularly advantageous when heat accumulation and heat extraction are simultaneous. The same applies to use a heat accumulator for cooling purposes.

angeordnete Strömungskanäle bzw. Strömungsflächen ergeben, kann auf einfache Weise dadurch erreicht werden, daß drei Platten miteinander verbunden werden. Die Ober- und Unterseite des so gebildeten Wärmetauschers weisen je einen Vor- und einen Rücklaufanschluß auf. Zwischen der mittleren Platte und der jeweils darüber und darunter befindlichen Platte ergeben sich flache Strömungskanäle bzw. Strömungsflächen. arranged flow channels or flow surfaces result, can be achieved in a simple manner by connecting three panels together. The top and bottom of the heat exchanger formed in this way each have a flow connection and a return connection. Between the middle The plate and the plate above and below it result in flat flow channels or flow surfaces.

Der Wärmetauscher weist zwei übereinander angeordnete Strömungskanäle bzw. Strömungsflächen 1,2 auf, von denen jeder Strömungskanal, bzw. Strömungsfläche je einen Vor- und einen Rücklaufanschluß 3>4 u. 5,6 besitzt. Um dem im Heiz- oder Kühlsystem herrschenden Druck standhalten zu'können, sind die drei Platten an mehreren Stellen 7 miteinander verbunden.The heat exchanger has two flow channels arranged one above the other or flow surfaces 1,2, of which each flow channel or flow surface is one fore and one Return connection 3> 4 and 5.6. To that in the heating or To be able to withstand the pressure prevailing in the cooling system, the three plates are connected to one another at several points 7.

Bei einer Fertigung in Stahl könnten drei Platten durch RoIl- und/oder Punktschweißverfahren miteinander verbunden werden. Da Ober- und Unterseite des Wärmetauschers identisch sein können, können die Platten in einem Arbeitsgang miteinander verschweißt werden. Wenn unprofilierte Bleche verwendet werden, können die Kanäle bzw. Strömungsflächen anschließend durch Aufblasen aufgeweitet werden.In the case of production in steel, three plates could be rolled and / or spot welding processes are connected to one another. Since the top and bottom of the heat exchanger can be identical, the plates can be joined together in one operation be welded. If unprofiled sheets are used, the channels or flow surfaces can then be expanded by inflation.

Bei einer Fertigung in Aluminium kann das Verbinden der Platten durch Walzschweißung erfolgen, wobei die Flächen, an denen keine Haftung erfolgen soll, vorher mit Farbe bedruckt werden können. Anschließend kann eine Aufweitung durch Aufblasen erfolgen.When manufacturing in aluminum, the joining of the Plates are made by roll welding, with the areas to which no adhesion is to take place previously printed with color can be. Then it can be expanded by inflating it.

Eine Fertigung in Kunststoff ist ebenfalls möglich, wobei das Blasverfahren und/oder Spiegelschweißung Anwendung finden könnte.Manufacture in plastic is also possible, using the blow molding process and / or mirror welding could.
