Abstract
Description
Die Erfindung betrifft einen Plattenwärmetauscher, der aus einem Stapel gleichgroßer und gleichförmig profilierter Platten besteht, in dem benachbarte Platten sich abwechselnd ihre Vorderseiten oder ihre Rückseiten zuwenden, und in dem die Platten an den Stellen, an denen sie sich berühren und gegeneinander abstützen, verschweißt oder verlötet sind. Ein derartiger Plattenwärmetauscher ist aus der FR-A-2 323 119 bekannt.The invention relates to a plate heat exchanger which a stack of equally large and uniformly profiled Plates exists in which neighboring plates alternate facing their front or back, and in that the plates where they touch and support each other, welded or soldered. Such a plate heat exchanger is known from FR-A-2 323 119.
Anwendungsgebiete dieses Wärmetauschers sind vor allem die Kühl- und Gefriertechnik mit verdampfenden und kondensierenden Medien, die Maschinenkühlung sowie Wärmeübertragungsvorgänge, bei denen ein Medium frei aus einem Behälter in den Wärmetauscher eintritt.Areas of application of this heat exchanger are primarily those Cooling and freezing technology with evaporating and condensing Media, machine cooling and heat transfer processes, where a medium is free from a container in the Heat exchanger enters.
Bei bekannten Wärmetauschern durchströmen wärmeabgebende und wärmeaufnehmende Medien Kanäle mit annähernd konstantem Querschnitt. Dieser Querschnitt kann um einen Mittelwert schwanken, z.B. durch den Einbau von Hindernissen, welche die Turbulenz der Strömung erhöhen und damit den Wärmeübergang verbessern sollen, er nimmt aber während des Wärmeaustausches weder kontinuierlich ab noch zu. Das gilt für die bekannten Röhrenwärmetauscher ebenso wie für bekannte Spiral- und Plattenwärmetauscher.In known heat exchangers flow through and heat-absorbing media channels with approximately constant cross-section. This cross section can fluctuate around an average, e.g. by installing obstacles that affect the turbulence increase the flow and thus improve the heat transfer should, but it takes place during the heat exchange neither continuously nor to. That applies to the known ones Tube heat exchangers as well as for known spiral and plate heat exchangers.
Für Wärmetauscher gilt das Prinzip, möglichst große Wärmetauscherflächen in einem möglichst kleinen Bauvolumen unterzubringen und große Wärmeübertragungsleistungen bei möglichst geringen Druckverlusten zu erreichen.The principle of the largest possible heat exchanger surface applies to heat exchangers to accommodate in the smallest possible construction volume and large heat transfer capacities if possible to achieve low pressure drops.
In den DE-PS 669442 und 862757 sowie in der DE-AS 1913226 wurde versucht, dieses Prinzip durch übereiandergeschichtete Platten zu realisieren, zwischen denen für jedes der am Wärmetausch beteiligte Medium ein in Form einer Spirale verlaufender Kanal angeordnet ist. Nach der FR-PS 2323119 werden diese Kanäle durch Warmpressen eingeformt. Beim Zusammenfügen der gleichgroßen und gleichförmigen Platten zu einem Stapel wird jede zweite gewendet, wodurch die Kanäle an den Seiten einer jeden Platte gegenläufig angeordnet sind. Sie haben einen annähernd konstanten Querschnitt.In DE-PS 669442 and 862757 and in DE-AS 1913226 tried to overlay this principle Realize plates between those for each of the most at the heat exchange medium involved is a spiral Channel is arranged. According to FR-PS 2323119 these channels are formed by hot pressing. When assembling of the same size and uniform plates in a stack is turned every second, creating channels on the sides each plate are arranged in opposite directions. They have an approximately constant cross section.
Die Medien sind gezwungen, die Kanäle in ihrer ganzen Länge zu durchlaufen. Dabei ist kein gleichmäßiger Wärmeübergang mit einem hohen Wirkungsgrad der Wärmeübertragung zu erreichen, weil bei der sich herausbildenden Strömung eine laminare Grenzschicht an den Wandungen entsteht, welche den Wärmeübergang behindert.The media are forced to use the entire length of the channels to go through. There is no even heat transfer to achieve a high efficiency of heat transfer, because with the emerging flow a laminar one Boundary layer on the walls, which is the heat transfer with special needs.
Um den Wärmeübergang zu verbessern, wurden Überströmöffnungen in die spiralig gewundenen Trennwände (DE-PS 2615977) oder axial in jede zweite Platte des Wärmetauschers (DE-PS 3210168) eingebracht. Der Fertigungsaufwand und der Materialeinsatz bei derartigen Wärmetauschern ist jedoch sehr hoch, ohne daß der Wirkungsgrad durch diese Maßnahmen wesentlich verbessert wird.In order to improve the heat transfer, overflow openings were created in the spirally wound partitions (DE-PS 2615977) or axially in every second plate of the heat exchanger (DE-PS 3210168) brought in. The manufacturing effort and the use of materials in such heat exchangers, however, is very high without the efficiency is significantly improved by these measures becomes.
Mit dem Wärmetauscher nach der DE-OS 3827828 soll dieser Nachteil soweit behoben werden, daß sogar ein Einsatz in der Raumfahrt in Erwägung gezogen wird. Dabei wird ein Medium durch spiralförmig angeordnete Rohre geleitet, während das andere Medium diese Rohre radial vom Umfang ins Zentrum umströmt, in dem ein geringerer Druck als am Umfang herrscht. Auch bei diesem Wärmetauscher überwiegt in den Rohrleitungen die laminare Grenzschicht.With the heat exchanger according to DE-OS 3827828 this should Disadvantage can be remedied so far that even an application in the Space is being considered. It becomes a medium passed through spirally arranged pipes while the other medium these tubes radially from the circumference to the center flows around, in which there is less pressure than on the circumference. This heat exchanger also predominates in the pipes the laminar boundary layer.
Als man erkannt hatte, daß Turbulenzen den Wärmeübergang fördern, wurde die Strömung durch den Einbau von Hindernissen turbulenter gestaltet.When it was recognized that turbulence promoted heat transfer, became the flow by installing obstacles designed more turbulent.
Bei Plattenwärmetauschern erfolgte dies vorrangig durch die Profilierung der Platten, wie z.B. in der DE-OS 4020735 dargelegt. Die Profilierung besteht meist aus einer wellenförmigen Prägung mit im Querschnitt gleichgroßen Wellenbergen und Wellentälern quer zur Ausbreitungsrichtung.For plate heat exchangers, this was primarily done by Profiling the panels, e.g. in DE-OS 4020735 spelled out. The profiling usually consists of a wavy one Embossing with wave crests of equal size in cross-section and troughs transverse to the direction of propagation.
Die gerade verlaufenden wellenförmigen Profilierungen bilden einen spitzen Winkel mit den Längsachsen der Platten, so daß bei Platten, die gegeneinander um 180° gedreht sind, sich die Wellen kreuzen und die Platten auf Abstand halten. In dem sich bildenden Spalt zwischen den Platten ist das in ihm strömende Medium einer ständigen Richtungsänderung bei sich periodisch änderndem Strömungsquerschnitt unterworfen. Die wellenförmige Profilierung stabilisiert außerdem die Platten, wodurch sie sehr dünn ausgebildet werden können. Das begünstigt ebenfalls den Wärmeübergang.Form the straight wavy profiles an acute angle with the longitudinal axes of the plates, so that for plates that are rotated 180 ° against each other cross the waves and keep the plates at a distance. By doing the gap that forms between the plates is in him flowing medium with a constant change of direction subject to periodically changing flow cross-section. The wavy profiling also stabilizes the panels, whereby they can be made very thin. That favors also the heat transfer.
Diese Vorteile hat man sich auch bei Plattenwärmetauschern für Regenerativ-Gasturbinen zunutze gemacht, zum Beispiel nach der US-PS 3424240. Bei derartigen Wärmetauschern begrenzt ein Stapel gewellter, ringförmiger Wärmetauscherplatten einen zentralen Eintrittskanal für die heißen Abgase der Turbine. Diese Abgase strömen radial zwischen Plattenpaaren, die ihrerseits im Gegenstrom von kühler Kompressorluft durchströmt werden, zu einer am Umfang angeordneten Auslaßleitung, die mit der Verbrennungskammer der Turbine in Verbindung steht. Die Platten sind gewellt, um den Wärmetausch zwischen dem heißen Gasstrom und der Kompressorluft zu verbessern. Die Energie der Abwärme der Turbine wird so auf die komprimierte Luft übertragen, wodurch sich der Wirkungsgrad der Turbine erhöht. Die ringförmigen Platten haben radial nur eine geringe Breite, so daß sich die vergrößernden Querschnitte zwischen den Platten auf die radial nach außen strömenden heißen Abgase kaum auswirken.These advantages are also found in plate heat exchangers used for regenerative gas turbines, for example according to US Pat. No. 3,424,240. Limited in such heat exchangers a stack of corrugated, annular heat exchanger plates a central inlet duct for the hot exhaust gases from the Turbine. These exhaust gases flow radially between pairs of plates, which in turn flows through countercurrent of cool compressor air become an outlet line arranged on the circumference, connected to the combustion chamber of the turbine stands. The plates are corrugated to allow heat exchange between them to improve the hot gas flow and the compressor air. The Energy from the waste heat from the turbine is thus compressed Transfer air, which increases the efficiency of the turbine elevated. The annular plates have only a small radial Width, so that the enlarging cross sections between the plates onto the hot exhaust gases flowing radially outwards hardly affect.
Bei den bekannten Ölkühlern wird der Ölfilter axial durch eine Schraubverbindung mit dem Wärmetauscher und dieser ebenso mit dem Motor verbunden, wie in der DE-OS 3440064, der DE-OS 3938254, der DE-OS 4039776 und der DE-OS 4128153 dargestellt und beschrieben. Das hat den Nachteil, daß die Bauform und die Größe des Filters durch den Kühler vorgegeben sind und daß die am Motor auftretenden Vibrationen über den Wärmetauscher auf den Filter übertragen werden, der bei dieser Art der Verbindung an einem relativ langem Hebelarm schwingt. Dadurch ist der Wärmetauscher großen dynamischen Belastungen ausgesetzt. In the known oil coolers, the oil filter is axially through a screw connection with the heat exchanger and this as well connected to the motor, as in DE-OS 3440064, the DE-OS 3938254, DE-OS 4039776 and DE-OS 4128153 are shown and described. This has the disadvantage that the design and the size of the filter are predetermined by the cooler and that the vibrations occurring on the engine via the heat exchanger are transferred to the filter, which in this type the connection swings on a relatively long lever arm. As a result, the heat exchanger is subject to high dynamic loads exposed.
Aufgabe der Erfindung ist es, einen kompakten Plattenwärmescher mit geringem Leistungsgewicht zu schaffen, der einem sich unter dem Einfluß von Wärme ausdehnenden Medium einen wachsenden Strömungsquerschnitt bietet und einem abkühlenden Medium mit abnehmendem Volumen einen sich verringernden Strömungsquerschnitt, und der dadurch die Strömung stabilisiert und den Wärmeübergang begünstigt. Außerdem soll dieser Plattenwärmetauscher die Bedingungen für den Anschluß eines Filters verbessern.The object of the invention is a compact plate heat exchanger to create with a low power to weight ratio unite under the influence of heat-expanding medium offers growing flow cross-section and a cooling Medium with decreasing volume a decreasing flow cross-section, and thereby stabilizing the flow and favors heat transfer. In addition, this plate heat exchanger the conditions for connecting a filter improve.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale gemäß dem Patentanspruch 1 gelöst.This object is achieved by the features according to
Die Platten sind so profiliert, daß sich benachbarte Platten entweder mit ihrem inneren und äußeren ebenen Rand oder mit ihren Profilierungen berühren und abstützen und zwischen sich einen Spalt einschließen. Vorzugsweise werden wellenförmige Profilierungen eingeprägt, die spiralförmig, insbesondere in Form einer archimedischen Spirale, verlaufen. Der Querschnitt der Wellen ist beliebig. Er kann sinus- oder trapezförmig sein. Jede Spirale beginnt und endet in einem bis zur Höhe der Wellenberge eingeprägten Plateau, in dessen Mitte je ein Durchbruch durch die Platte eingeformt ist.The plates are profiled so that adjacent plates either with its inner and outer flat edge or with touch and support their profiles and between themselves include a gap. Preferably be wavy Profiles embossed in a spiral, especially in Archimedean spiral shape. The cross section the waves are arbitrary. It can be sinusoidal or trapezoidal be. Each spiral begins and ends in one up to the height of the wave crests embossed plateau, in the middle of each one Breakthrough is formed through the plate.
An den Stellen, an denen sich die Platten im Stapel berühren, werden sie verschweißt oder verlötet, das heißt an den inneren und äußeren ebenen Rändern, an den sich kreuzenden Wellenbergen und den Plateaus. Die Durchbrüche inmitten der Plateaus werden so zu axial angeordneten Kanälen zwischen den Spalten für das wärmeaufnehmende Medium.Where the plates in the stack touch, are they welded or soldered, that is to the inner and outer flat edges, at the intersecting Wave crests and the plateaus. The breakthroughs in the middle of the Plateaus thus become axially arranged channels between the Columns for the heat-absorbing medium.
Die Platten werden vorzugsweise nacheinander mittels Laser verschweißt. Sie können aber auch mit einer Lotschicht versehen und unter Wärmezuführung im Stapel verlötet werden. Der Plattenwärmetauscher ist von eine Gehäuse umschlossen, in dem vorteilhaft ein Filter, z.B. ein Ölfilter, angeordnet werden kann, der den gesamten Umfang des Wärmetauschers umschließt und daher eine um ein Vielfaches größere Filterfläche aufweist als bekannte axial anzuschließende Filter. Dieser Filter zeichnet sich durch geringere Druckverluste und eine größere Nutzungsdauer aus.The plates are preferably lasered one after the other welded. But you can also provide a solder layer and soldered in the stack with heat. Of the Plate heat exchanger is enclosed in a housing in which advantageously a filter, e.g. an oil filter can, which encloses the entire circumference of the heat exchanger and therefore has a filter area many times larger as known axially connectable filters. This filter is characterized by lower pressure drops and a larger one Useful life.
Bei dieser Anordnung des Filters werden die vom Motor übertragenen Vibrationen gedämpft und beeinträchtigen kaum noch die Stabilität des Wärmetauschers.With this arrangement of the filter, those transmitted by the engine are transmitted Vibrations are dampened and hardly affect the stability of the heat exchanger.
Der höchste Wirkungsgrad der Wärmeübertragung wird mit dem erfindungsgemäßen Plattenwärmetauscher mit Medien erreicht, die während des Wärmetausches den Übergang von der gasförmigen zur flüssigen Phase oder von der flüssigen zur gasförmigen Phase durchlaufen. Bei diesen Phasenübergängen verändern die Medien extrem ihre Volumina. Die damit bei herkömmlichen Wärmetauschern auftretenden extremen Änderungen des Druckes werden mit dem vorgeschlagenen Plattenwärmetauscher weitgehend vermieden, weil dem expadierenden Medium ein mit dem Radius wachsender Strömungsquerschnitt und dem kondensierenden Medium ein sich im gleichen Maße verengender Strömungsquerschnitt zur Verfügung steht. Das erhöht den Wirkungsgrad des Wärmeüberganges und stellt geringere Anforderungen an die Festigkeit des Wärmetauschers.The highest efficiency of heat transfer is with the plate heat exchanger according to the invention achieved with media, which during the heat exchange the transition from the gaseous to the liquid phase or from the liquid to the gaseous Go through phase. Change at these phase transitions the media extremely their volumes. The conventional Extreme changes in pressure occurring in heat exchangers are largely with the proposed plate heat exchanger avoided because the expanding medium with the Radius increasing flow cross section and the condensing Medium is a flow cross section that narrows to the same extent is available. That increases efficiency of heat transfer and places lower demands on the Heat exchanger strength.
