Description

Technisches GebietTechnical area

Die Erfindung betrifft einen Kondensator mit einem Rohr-Rippenblock mit Rohren und zwischen den Rohren angeordneten Rippen, wobei die Rohre mit ihren gegenüberliegenden Enden jeweils in Öffnungen von beidseitig des Rohr-Rippenblocks angeordneten Sammelrohren aufgenommen sind, gemäß dem Oberbegriff von Anspruch 1. Solch ein Kondensator ist bekannt aus JP2001108331 .The invention relates to a condenser with a tube-fin block with tubes and arranged between the tubes ribs, wherein the tubes are received with their opposite ends respectively in openings of both sides of the tube-fin block arranged collecting tubes, according to the preamble of claim 1. Such a capacitor is known from JP2001108331 ,

Stand der TechnikState of the art

Kondensatoren sind im Stand der Technik für Kältemittelkreisläufe für Klimaanlagen von Kraftfahrzeugen bekannt. Dabei weisen die Kondensatoren üblicher Weise einen Rohr-Rippenblock mit Rohren und zwischen den Rohren angeordneten Rippen auf. Die Rohre dienen als erste Fluidkanäle der Durchströmung eines Kältemittels, wobei die Rippen die zweiten Fluidkanäle für die durchströmende. Luft als kühlendes Fluid bilden. Dabei sind die Rohre mit ihren gegenüberliegenden Enden jeweils in Öffnungen von beidseitig des Rohr-Rippenblocks angeordneten Sammelrohren aufgenommen. Die Sammelrohre dienen dem Sammeln von Kältemittel aus einer Flut mit Rohren und dem Weiterleiten des Kältemittels in eine weitere Flut mit weiteren Rohren.Capacitors are known in the art for refrigerant circuits for air conditioning systems of motor vehicles. The capacitors usually have a tube-fin block with tubes and arranged between the tubes ribs. The tubes serve as the first fluid channels of the flow through a refrigerant, wherein the ribs, the second fluid channels for the flowing through. Forming air as a cooling fluid. In this case, the tubes are received with their opposite ends in each case in openings arranged on both sides of the tube-rib block manifolds. The manifolds are used to collect refrigerant from a flood with pipes and the forwarding of the refrigerant in another flood with other pipes.

Solche Kondensatoren sind beispielswiese durch die EP 0 359 358 A1 bekannt geworden. Dabei strömt das Kältemittel zwischen den Sammelrohren in Reihen von Rohren in verschiedenen Fluten durch den Kondensator. Die Anzahl der Rohre reduziert sich dabei von Flut zu Flut, weil das Kältemittel entlang seines Strömungsweges durch die Fluten enthitzt, kondensiert und unterkühlt wird. Die dampfförmige Phase reduziert dabei sein Volumen bis zum vollständig verflüssigten Zustand.Such capacitors are beispielswiese by the EP 0 359 358 A1 known. In this case, the refrigerant flows through the condenser between the headers in rows of pipes in different flows. The number of tubes is reduced from tide to tide, because the refrigerant is deintercalated along its flow path through the floods, condensed and supercooled. The vapor phase thereby reduces its volume to completely liquefied state.

Diese Kondensatoren zeigen die Eigenschaft, das die Unterkühltemperatur von der Kältemittelmenge im Kreislauf abhängt, weil dadurch mit der Kältemittelmenge die Länge der Fluidsäule des Kältemittels entlang der Fluten variiert.These capacitors show the property that the subcooling temperature depends on the amount of refrigerant in the circuit, because it varies with the amount of refrigerant, the length of the fluid column of the refrigerant along the floods.

Daher sind Kondensatoren mit integriertem Sammlervolumen entwickelt worden, bei welchen parallel zu einem Sammelrohr ein Sammlervolumen vorgesehen ist, wobei die Überströmung vom Rohr-Rippenblock des Kondensators zum Sammler und zurück wieder zum Rohr-Rippenblock zwischen der Kondensationszone und der Unterkühlzone angeordnet ist, so dass bei gefülltem Sammler die Unterkühlzone immer definiert mit flüssigem Kältemittel gefüllt ist. Dies bewirkt, dass im Temperatur vs. Füllmenge-Diagramm ein Plateau in der Unterkühltemperatur vorliegt. Dies führt zu einem stabilen Betrieb des Kältemittelkreislaufs, weil die Unterkühltemperatur über weite Betriebsbereiche des Kondensators stabil ist. Ein solcher Kondensator mit Sammler ist durch die DE 42 38 853 C2 bekannt geworden.Therefore, condensers with integrated accumulator volume have been developed in which a collector volume is provided parallel to a manifold, wherein the overflow from the tube-fin block of the condenser to the collector and back to the tube-fin block between the condensation zone and the sub-cooling zone is arranged, so that at filled collector the subcooling zone is always filled with liquid refrigerant. This causes in the temperature vs. Filling quantity diagram is a plateau in the supercooling temperature. This results in stable operation of the refrigerant circuit because the subcooling temperature is stable over wide operating ranges of the condenser. Such a capacitor with collector is through the DE 42 38 853 C2 known.

Soll der Bauraum für den Sammler vergrößert.werden, um das Füllvolumen zu erhöhen, so dass sich die Plateaulänge des oben genannten Diagramms verbreitert, so ist dieses vom verfügbaren Bauraum in der Fahrzeugfront abhängig, die grundsätzlich beschränkt ist. Das verfügbare Sammlervolumen kann nicht durch beliebige Durchmesservergrößerung des Sammlers erhöht werden. Auch kann die Länge des Sammlers in der Längsrichtung des Sammlers nicht beliebig erhöht werden, da der Sammler ansonsten an die Motorabdeckhaube anstoßen würde.If the installation space for the collector is to be increased in order to increase the filling volume, so that the plateau length of the above-mentioned diagram widens, then this depends on the available installation space in the vehicle front, which is basically limited. The available collector volume can not be increased by any increase in the diameter of the collector. Also, the length of the collector in the longitudinal direction of the collector can not be increased arbitrarily, since the collector would otherwise abut the Motorabdeckhaube.

Daher ist es die Aufgabe der vorliegenden Erfindung einen Kondensator zu schaffen, der ein erhöhtes Sammlervolumen aufweist, um die Plateaulänge im Temperatur vs. Füllmenge-Diagramm für eine verbesserte Unterkühlung zu verlängern.Therefore, it is the object of the present invention to provide a condenser which has an increased collector volume to control the plateau length in temperature vs. temperature. Extend capacity chart for improved subcooling.

Die Aufgabe der vorliegenden Erfindung wird durch einen Kondensator mit den Merkmalen gemäß Anspruch 1 gelöst.The object of the present invention is achieved by a capacitor having the features according to claim 1.

Durch die Anordnung eines ersten und eines zweiten Sammlers kann das geforderte Sammlervolumen erreicht werden und dennoch eine geringe Bautiefe beibehalten werden.By arranging a first and a second collector, the required collector volume can be achieved and yet a small overall depth can be maintained.

Dabei ist es zweckmäßig, wenn der zweite Sammler benachbart zu dem zweiten Sammelrohr angeordnet ist und in Fluidverbindung zu dem zweiten Sammelrohr ist. Dadurch wird der erste Sammler und der zweite Sammler an gegenüberliegenden Sammelrohren benachbart angeordnet. Dadurch wird nicht nur eine geringe Bautiefe erreicht, sondern es ergibt sich auch eine gute Gewichtsverteilung hinsichtlich der im Fahrzeug auftretenden Schwingungen bzw. Beschleunigungen.It is expedient if the second collector is arranged adjacent to the second manifold and is in fluid communication with the second manifold. Thereby, the first collector and the second collector are arranged adjacent to opposite headers. As a result, not only a small overall depth is achieved, but it also results in a good weight distribution with respect to the vibrations or accelerations occurring in the vehicle.

Auch ist es zweckmäßig, wenn der zweite Sammler benachbart zum ersten Sammler angeordnet ist und mit dem ersten Sammler in Fluidverbindung steht. Dadurch wird erreicht, dass das Volumen zur Speicherung sich vergrößert. Je nach Gestaltung der Durchströmung des ersten Sammlers kann in einer Verschaltung beispielsweise der erste Sammler nur durch den zweiten Sammler durchströmbar sein. In einer anderen Verschaltung kann der erste Sammler beispielsweise alleine durchströmbar sein, wobei die direkte Strömung des Kältemittels an dem zweiten Sammler vorbei in den Unterkühlbereich des Rohr-Rippenblocks strömt. Der zweite Sammler kann bei Anordnung eines Trockners und/oder Filters der Bevorratung des Kältemittels und ggf. der Trocknung bzw. Filterung des Kältemittels dienen. Wird im ersten Sammler ein Filter und/oder Trockner angeordnet, so dient dieser erste Sammler ggf. der Bevorratung des Kältemittels und ggf. der Trocknung bzw. Filterung des Kältemittels.It is also expedient if the second collector is arranged adjacent to the first collector and is in fluid communication with the first collector. This ensures that the volume increases for storage. Depending on the design of the flow through the first collector, for example, the first collector can only be flowed through by the second collector in an interconnection. In another Interconnection, the first collector, for example, be flowed through alone, the direct flow of the refrigerant flows past the second collector in the sub-cooling region of the tube-fin block. When arranging a dryer and / or filter, the second collector can serve to store the refrigerant and possibly to dry or filter the refrigerant. If a filter and / or dryer is arranged in the first collector, then this first collector serves, if necessary, to store the refrigerant and if necessary to dry or filter the refrigerant.

Erfindungsgmäß steht der erste Sammler über eine erste Überströmöffnung und mit einer zweiten Überströmöffnung mit dem ersten Sammelrohr in Fluidverbindung. Dabei ist es vorteilhaft, wenn im Sammelrohr zwischen den beiden Überströmöffnungen eine Trennwand zwischen einem Kondensierbereich und einem Unterkühlbereich angeordnet ist. Dabei ist es auch vorteilhaft, wenn in dem ersten Sammler zwischen den Überströmöffnungen zumindest ein Filter vorgesehen ist, damit das in den Sammler einströmende Kältemittel nach Umlenkung gefiltert wieder aus dem Sammler ausströmen kann. Alternativ kann auch eine Trennwand vorgesehen sein, welche das unmittelbare Überströmen von der ersten zur zweiten Überströmöffnung verhindern mag. So kann beispielsweise das Kältemittel über weitere Überströmöffnungen in den zweiten Sammler strömen.According to the invention, the first header is in fluid communication with the first header via a first transfer port and with a second transfer port. It is advantageous if a partition wall between a Kondensierbereich and a subcooling is arranged in the manifold between the two overflow. It is also advantageous if at least one filter is provided in the first collector between the overflow openings, so that the refrigerant flowing into the collector after being filtered can again flow out of the collector. Alternatively, a partition may be provided which may prevent the immediate overflow from the first to the second overflow. For example, the refrigerant can flow via further overflow openings into the second collector.

Erfindungsgemäß steht der zweite Sammler über eine dritte Überströmöffnung und mit einer vierten Überströmöffnung mit dem zweiten Sammelrohr in Fluidverbindung. Dabei ist es auch vorteilhaft, wenn im Sammelrohr zwischen den beiden Überströmöffnungen eine Trennwand zwischen einem ersten Unterkühlbereich und einem zweiten Unterkühlbereich angeordnet ist. Dabei ist es auch vorteilhaft, wenn in dem zweiten Sammler zwischen den Überströmöffnungen zumindest ein Filter vorgesehen ist, damit das in den Sammler einströmende Kältemittel nach Umlenkung gefiltert wieder aus dem Sammler ausströmen kann.According to the invention, the second collector is in fluid communication via a third overflow opening and with a fourth overflow opening with the second collection pipe. It is also advantageous if a partition wall between a first subcooling region and a second subcooling region is arranged in the collecting pipe between the two overflow openings. In this case, it is also advantageous if at least one filter is provided in the second collector between the overflow openings, so that the refrigerant flowing into the collector can flow filtered out of the collector again after being deflected.

Vorteilhaft ist auch, wenn der erste Sammler über eine dritte Überströmöffnung und mit einer vierten Überströmöffnung mit dem zweiten Sammler in Fluidverbindung steht. Die beiden Sammler können dabei parallel oder seriell angeordnet und/oder anströmbar sein.It is also advantageous if the first header is in fluid communication with the second header via a third overflow opening and with a fourth overflow opening stands. The two collectors can be arranged parallel or serially and / or can be flowed on.

Auch ist es zweckmäßig, wenn der Rohr-Rippenblock in Fluten parallel mit dem Kältemittel durchströmter Rohre unterteilt ist, dabei sind die Fluten in Fluidströmungsrichtung nacheinander durchströmbar, wobei zwischen dem ersten Sammler und dem zweiten Sammler eine Flut parallel durchströmter Rohre angeordnet ist, die zwischen der ausströmseitigen Überströmöffnung des ersten Sammler und der einströmseitigen Überströmöffnung des zweiten Sammers angeordnet ist. Diese Flut ist dabei vorzugsweise eine Flut der Unterkühlstrecke, die zur Unterkühlung des Kältemittels vorgesehen ist.It is also expedient if the tube-fin block is subdivided in floods parallel to the refrigerant flow-through tubes, the floods are successively flowed through in the fluid flow direction, wherein between the first collector and the second collector, a flood of parallel flowed tubes is arranged between the outflow-side overflow opening of the first collector and the inflow-side overflow opening of the second accumulator is arranged. This flood is preferably a flood of subcooling, which is provided for supercooling of the refrigerant.

Dabei ist es zweckmäßig, wenn zwischen einem Einströmanschluss zur Einströmung des Fluids in den Rohr-Rippenblock und dem ersten Sammler zumindest eine Flut parallel durchströmter Rohre angeordnet ist. Vorteilhaft sind mehrere Fluten zwischen dem Einströmanschluss und dem ersten Sammler angeordnet. Dies bewirkt vorteilhaft, dass das Kältemittel ausreichend enthitzt und kondensiert werden kann, bevor es in den ersten Sammler eintritt.It is expedient if between a Einströmanschluss to the inflow of the fluid into the tube-fin block and the first collector at least a flood of parallel flowed through tubes is arranged. Advantageously, a plurality of floods are arranged between the inflow connection and the first collector. This advantageously causes the refrigerant to be sufficiently de-entrained and condensed before entering the first header.

Auch ist es vorteilhaft, wenn zwischen dem ersten Sammler und einem Ausströmanschluss zur Ausströmung des Fluids aus dem Rohr-Rippenblock zumindest eine Flut parallel durchströmter Rohre angeordnet ist. Diese zumindest eine Flut dient bevorzugt der Unterkühlung des Kältemittels.It is also advantageous if at least one tide of parallel-flowed tubes is arranged between the first header and an outlet connection to the outflow of the fluid from the tube-fin block. This at least one flood is preferably used for the subcooling of the refrigerant.

Auch ist es zweckmäßig, wenn zwischen dem zweiten Sammler und einem Ausströmanschluss zur Ausströmung des Fluids aus dem Rohr-Rippenblock zumindest eine Flut parallel durchströmter Rohre angeordnet ist. Diese zumindest eine Flut dient bevorzugt der Unterkühlung des Kältemittels.It is also expedient if at least one tide of parallel-flowed tubes is arranged between the second header and an outlet connection to the outflow of the fluid from the tube-fin block. This at least one flood is preferably used for the subcooling of the refrigerant.

Vorteilhaft ist es, wenn ein Filter und/oder Trockner vorgesehen ist, der oder die im ersten und/oder im zweiten Sammler angeordnet ist. So kann im ersten Sammler jeweils ein Filter und/oder Trockner angeordnet sein und ebenso im zweiten Sammler ein Filter und/oder ein Trockner. Vorteilhaft ist es, wenn im zweiten Sammler der Trockner angeordnet ist und dieser Sammler nicht in der direkten Durchströmung angeordnet ist.It is advantageous if a filter and / or dryer is provided, which is arranged in the first and / or in the second collector. So in the first collector in each case a filter and / or dryer be arranged and also in the second collector a filter and / or a dryer. It is advantageous if the dryer is arranged in the second collector and this collector is not arranged in the direct flow.

Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention

Die Fig. 1 zeigt einen Kondensator 1 mit einem Rohr-Rippenblock 2 mit Rohren 3 und zwischen den Rohren 3 angeordneten Rippen 4. Die Rohre 3 weisen Rohrenden 5, 6 auf, die sich gegenübertiegen. Die Rohre 3 sind mit ihren Rohrenden 5, 6 in Öffrungen 7 von Sammelrohren 8, 9 aufgenommen und abgedichtet, so dass die Rohre 3 mit den Sammelrohren 8, 9 in Fluidverbindung stehen.The Fig. 1 shows a condenser 1 with a tube fin block 2 with tubes 3 and arranged between the tubes 3 ribs 4. The tubes 3 have pipe ends 5, 6, which are opposite. The tubes 3 are received and sealed with their tube ends 5, 6 in Öffrungen 7 of headers 8, 9, so that the tubes 3 are in fluid communication with the manifolds 8, 9.

Die Sammelrohre 8, 9 sind beiderseits des Rohr-Rippenblocks 2 angeordnet und dienen der Verteilung des Fluids auf eine Mehrzahl von Rohren 3 bzw. einer Sammlung eines Fluids aus einer Mehrzahl von Rohren 3. Der Rohr-Rippenblock 2 wird bevorzugt in einer Mehrzahl von Fluten nacheinander durchströmt, wobei jeweils eine Anzahl von Rohren 3 zu einer Flut zusammengefasst sind, indem diese Rohre parallel von Fluid durchströmt werden. Dazu sind in den Sammelrohren 8, 9 Trennwände geeignet angeordnet, um eine Aufteilung des Fluids auf eine vorgegebene Anzahl von Rohren 3 einer Flut zu ermöglichen.The manifolds 8, 9 are disposed on both sides of the tube-fin block 2 and serve to distribute the fluid to a plurality of tubes 3 and a collection of fluid from a plurality of tubes 3. The tube-fin block 2 is preferably in a plurality of floods flows through successively, in each case a number of tubes 3 are combined to form a flood, by these tubes are flowed through in parallel by fluid. For this purpose, 9 partition walls are suitably arranged in the headers 8, 9 to allow a division of the fluid to a predetermined number of tubes 3 a flood.

In Fig. 1 strömt das Fluid in fünf Fluten 10, 11, 12, 13, 14 durch den Rohr-Rippenblock 2. Dabei strömt das Fluid durch den Einlassanschluss 15 in das Sammelrohr 8 ein, wo es aufgrund einer Trennwand 16 auf die erste Flut 10 aufgeteilt wird. Das Fluid durchströmt die Rohre 3 der Flut 10 parallel und es wird in dem Sammelrohr 9 wiederum gesammelt, von wo es auf die Flut 11 und die diesbezüglichen Rohre aufgeteilt wird, so dass diese Flut zum nächsten Sammelrohr durchströmt wird. Dabei ist eine weitere Trennwand 17 im Sammelrohr 9 vorgesehen. Im Anschluss daran durchströmt das Fluid die Rohre 3 der Flut 11 und gelangt in das Sammelrohr 8, wo es wiederum auf die Flut 12 umgelenkt wird, weil eine weitere Trennwand 18 im Sammelrohr vorgesehen ist. Das Fluid strömt durch die Flut 12 und die diesbezüglichen Rohre 3 und gelangt wiederum in das Sammelrohr 9, von wo es aufgrund der Anordnung der Trennwand 19 in einen Sammler 20 durch eine Überströmöffnung 21 einströmt.In Fig. 1 The fluid flows in five floods 10, 11, 12, 13, 14 through the tube-fin block 2. In this case, the fluid flows through the inlet port 15 into the manifold 8, where it is divided due to a partition wall 16 to the first flood 10. The fluid flows through the tubes 3 of the flood 10 in parallel and it is again collected in the collecting tube 9, from where it is divided between the flood 11 and the relevant tubes, so that this flood is passed through to the next collecting tube. In this case, a further partition 17 is provided in the manifold 9. Following this, the fluid flows through the tubes 3 of the flood 11 and enters the collecting tube 8, where it is in turn deflected to the flood 12, because a further partition wall 18 is provided in the collecting tube. The fluid flows through the flood 12 and the relevant tubes 3 and in turn passes into the collecting pipe 9, from where it flows into an accumulator 20 through an overflow opening 21 due to the arrangement of the dividing wall 19.

Das Fluid wird in dem Sammler 20 gesammelt und strömt durch eine weitere Überströmöffnung 22 wieder in das Sammelrohr 9 zwischen die Trennwand 19 und die Trennwand 23 und strömt anschließend durch die Flut 13 und die diesbezüglichen Rohre, zum Sammelrohr 8 in einen Abschnitt zwischen der Trennwand 18 und der Trennwand 24. Von dort strömt das Fluid durch eine Überströmöffnung 25 in den Sammler 26 und wird dort gesammelt und strömt durch die Überströmöffnung 27 wieder in das Sammelrohr 8 ein. Es wird dort auf die Flut 14 verteilt und durchströmt den Rohr-Rippenblock 2 und die Rohre 3 der Flut 14 zum Sammelrohr 9, wo es durch einen Auslassanschluss 28 aus dem Kondensator 1 ausgeleitet wird, wobei es durch ein weiteres Rohr 29.zu einem Flansch 30 geführt wird.The fluid is collected in the collector 20 and flows through another overflow opening 22 again into the collecting pipe 9 between the partition wall 19 and the partition wall 23 and then flows through the flood 13 and the related pipes, to the collecting pipe 8 in a portion between the partition 18th and the partition 24. From there, the fluid flows through an overflow opening 25 into the collector 26 and is collected there and flows through the overflow 27 again into the manifold 8 a. It is there distributed on the flood 14 and flows through the tube-fin block 2 and the tubes 3 of the flood 14 to the manifold 9, where it is discharged through an outlet port 28 from the condenser 1, where it through a further tube 29.zu a flange 30 is guided.

Der Sammler 20 ist somit benachbart zu dem Sammelrohr 9 angeordnet und der Sammler 26 ist benachbart zu dem Sammelrohr 8 angeordnet. Die beiden Sammler 20, 26 sind somit parallel zueinander und zu benachbarten Sammelrohren 8, 9 angeordnet, wobei je ein Sammler 20, 26 jeweils benachbart zu den jeweils gegenüberliegenden Sammelrohren 8, 9 angeordnet ist.The collector 20 is thus disposed adjacent to the manifold 9 and the collector 26 is disposed adjacent to the manifold 8. The two headers 20, 26 are thus arranged parallel to one another and to adjacent headers 8, 9, wherein each one collector 20, 26 is disposed adjacent to the respective opposite headers 8, 9.

In Fig. 1 ist zu erkennen, dass die axiale Länge der Sammler kürzer ist als das benachbarte Sammelrohr, da oberhalb des Sammlers 26 bzw. unterhalb des Sammlers 20 jeweils ein Auslass- bzw. Einlassanschluss 15, 28 vorgesehen ist, um das Fluid, insbesondere Kältemittel, in den Kondensator einzulassen bzw. aus dem Kondensator auszulassen. In einer alternativen Ausgestaltung kann das Sammelrohr und der benachbarte Sammler auch gleich lang oder einseitig- oder beidseitig länger ausgebildet sein, wenn der Einlass- bzw. Auslassanschluss zu einer Seite hin gedreht angeordnet sind, dass sie nicht mit einem Sammler kollidieren.In Fig. 1 It can be seen that the axial length of the collector is shorter than the adjacent manifold, since above the collector 26 and below the collector 20 each have an outlet or inlet port 15, 28 is provided to the fluid, in particular refrigerant, in the To let condenser in or out of the condenser. In an alternative embodiment, the collecting tube and the adjacent collector may also be the same length or longer formed on one or both sides, if the inlet or outlet port are arranged rotated to one side, that they do not collide with a collector.

Im Ausführungsbeispiel der Fig. 1 sind beiderseits des Sammlers Befestigungselemente 31 vorgesehen, die als Befestigungsftansch ausgebildet sind und mittels welchen der Kondensator 1 beispielsweise im Fahrzeug befestigbar ist. Die Befestigungselemente 31 sind vorteilhaft einteilig mit dem jeweiligen Sammler 20, 26 ausgebildet, wobei es vorteilhaft sein kann, wenn die Sammler beispielsweise als extrudierte Bauteile ausgebildet sind, wobei die Befestigungselemente mit dem Sammlervolumen extrudiert werden können. In einem alternativen Ausführungsbeispiel können die Befestigungselemente auch mit dem jeweiligen Sammler 20, 26 verbunden werden, wie beispielsweise durch Löten.In the embodiment of Fig. 1 On both sides of the collector fastening elements 31 are provided, which are designed as a mounting flange and by means of which the capacitor 1, for example, in the vehicle can be fastened. The fastening elements 31 are advantageously formed in one piece with the respective collector 20, 26, it may be advantageous if the collectors are formed for example as extruded components, wherein the fastening elements with the collector volume can be extruded. In an alternative embodiment, the fasteners may also be connected to the respective collector 20, 26, such as by soldering.

Die Fig. 2 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Kondensators 50, bei welchem der Rohr-Rippenblock 51 im Wesentlichen gleich dem Rohr-Rippenblock 2 der Fig. 1 ausgebildet ist. Die Durchströmung des Rohr-Rippenblocks 51 erfolgt in fünf Fluten 52 bis 56, wobei zwischen der dritten Flut 54 und der vierten Flut 55 kein Sammler parallel zu dem Sammelrohr 57 angeordnet ist, sondern zwischen der dritten Flut 54 und der vierten Flut 55 lediglich eine Umlenkung im Sammelrohr 57 vorliegt. Parallel zu dem Sammelrohr 58 hingegen ist ein erster Sammler 59 angeordnet, zu welchem parallel ein zweiter Sammler 60 angeordnet ist. Der zweite Sammler 60 ist somit parallel zu dem ersten Sammler 59 und parallel zum Sammelrohr 58 angeordnet, wobei der Sammler 59 zwischen dem Sammelrohr 58 und dem Sammler 60 angeordnet ist. Die Durchströmung des ersten Sammlers 59 erfolgt gemäß dem dargestellten Pfeil ausgehend vom Sammelrohr 58 und der Überströmöffnung 61 vom Sammelrohr 58 in den ersten Sammler 59 und über eine weitere Überströmöffnung 62 in den zweiten Sammler 60. Von dem zweiten Sammlervolumen 60 tritt das Fluid durch die Überströmöffnung 63 wieder in den ersten Sammler 59 ein und von dort durch die Überströmöffnung 64 in das Sammelrohr 58 zurück. Von dort strömt das Fluid wieder durch die Flut 56 der Rohre des Rohr-Rippenblocks zum Sammelrohr 57, von wo es aus dem Kondensator 50 austritt.The Fig. 2 shows another embodiment of a capacitor 50 according to the invention, in which the tube-fin block 51 is substantially equal to the tube-fin block 2 of Fig. 1 is trained. The flow through the tube-fin block 51 takes place in five floods 52 to 56, wherein between the third flood 54 and the fourth flood 55 no collector is arranged parallel to the manifold 57, but between the third flood 54 and the fourth flood 55, only a deflection present in the manifold 57. In contrast to the manifold 58, however, a first collector 59 is arranged, to which a second collector 60 is arranged in parallel. The second collector 60 is thus arranged parallel to the first collector 59 and parallel to the manifold 58, wherein the collector 59 is disposed between the manifold 58 and the collector 60. The flow through the first collector 59 takes place according to the illustrated arrow, starting from the manifold 58 and the overflow 61 from the manifold 58 into the first collector 59 and via a further overflow 62 into the second collector 60. From the second accumulator volume 60, the fluid passes through the overflow 63 back into the first collector 59 and from there through the overflow 64 into the manifold 58 back. From there, the fluid flows again through the flood 56 of the tubes of the tube-fin block to the manifold 57, from where it exits from the condenser 50.

Im Ausführungsbeispiel der Fig. 2 sind Befestigungselemente 65 vorgesehen, wobei die Befestigungselemente benachbart dem Sammelrohr 57 angeordnet sind und mit dem Sammelrohr 57 verbunden sind, wobei die Befestigungselemente 65 benachbart dem Sammler 60 mit dem Sammler 60 verbunden sind. Vorteilhaft ist es, wenn die Befestigungselemente 65 neben dem Sammelrohr 57 angeordnet und mit dem Sammelrohr 57 verlötet sind. Bei den Befestigungselementen 65 benachbart zum Sammler 60 kann es vorteilhaft sein, wenn die Befestigungselemente 65 mit dem Sammler 60 einteilig ausgebildet sind, wie beispielsweise extrudiert. Auch können Befestigungselemente 65 mit dem Sammler 60 verlötet sein.In the embodiment of Fig. 2 fasteners 65 are provided with the fasteners disposed adjacent the manifold 57 and connected to the manifold 57 with the fasteners 65 adjacent the collector 60 connected to the collector 60. It is advantageous if the fastening elements 65 are arranged next to the collecting tube 57 and are soldered to the collecting tube 57. In the fasteners 65 adjacent to the collector 60, it may be advantageous if the fasteners 65 are integrally formed with the collector 60, such as extruded. Also, fasteners 65 may be soldered to the collector 60.

Bei dem Ausführungsbeispiel der Fig. 2 kann es auch vorteilhaft sein, wenn die beiden Sammler 59, 60 einteilig miteinander, beispielsweise durch Extrudierten, ausgebildet sind.In the embodiment of the Fig. 2 It may also be advantageous if the two collectors 59, 60 are integrally formed with each other, for example by extruding.

Die Fig. 3 zeigt den Kondensator 50 der Fig. 2 noch einmal im Detail, wobei dargestellt ist, dass im Sammler 60 ein Einsatz 66 vorgesehen ist, welcher durch eine Öffnung 67 im Bodenbereich des Sammlers 60 einführbar ist, wobei der Böden beispielsweise mittels eines Deckels verschließbar ist. Der Einsatz 66 ist vorteilhaft ein Trockner gegebenenfalls mit einem Filter und/oder einer Dichtlippe, so dass zwischen den Überströmöffnungen 62 und 63 eine Dichtlippe 68 vorgesehen sein kann, so dass der Filter des Trocknereinsatzes 66 zwangsweise durchströmbar ist. Alternativ kann auch lediglich ein Trocknereinsatz vorgesehen sein, der ohne Zwangsdürchströmung eines Filters ausgebildet ist.The Fig. 3 shows the capacitor 50 of Fig. 2 again in detail, wherein it is shown that in the collector 60 an insert 66 is provided, which is insertable through an opening 67 in the bottom region of the collector 60, wherein the floors, for example, by means of a lid is closed. The insert 66 is advantageously a dryer optionally with a filter and / or a sealing lip, so that between the overflow openings 62 and 63, a sealing lip 68 may be provided, so that the filter of the dryer insert 66 is forcibly flowed through. Alternatively, it is also possible to provide only one dryer insert which is designed without forced draft flow of a filter.

Die Fig. 4 zeigt die Anordnung der beiden Sammler 59, 60 noch einmal im Detail. Die Überströmöffnung 61 und die Überströmöffnung 64 dienen dem Zufluss bzw. dem Abfluss des Fluids in den ersten Sammler 59 bzw. aus dem ersten Sammler 59. Zwischen den beiden Überströmöffnungen 61, 64 ist eine Scheibe 69 vorgesehen, die eine unmittelbare Durchströmung von der Überströmöffnung 61 zur Überströmöffnung 64 verhindert. Das Fluid strömt nach Einströmung durch die Überströmöffnung 61 durch die Überströmöffnung 62 zum Sammler 60. Der Sammler 60 ist mit dem Einsatz 66 versehen, welcher die Dichtlippe 68 aufweist, so dass das.Fluid von der Überströmöffnung 62 durch den Einsatz 66 zur Überströmöffnung 63 strömt und von dort aus dem Sammler 60 in den Sammler 59 und von dort durch die Überströmöffnung 64 aus dem Sammler 59. Die Öffnung 67 ist in der Fig. 4 durch den Verschluss 70 verschlossen.The Fig. 4 shows the arrangement of the two collectors 59, 60 again in detail. The overflow opening 61 and the overflow opening 64 serve for the inflow or outflow of the fluid into the first collector 59 or out of the first collector 59. Between the two overflow openings 61, 64 a disc 69 is provided, which directly flows from the overflow opening 61 prevents overflow opening 64. After flowing through the overflow opening 61, the fluid flows through the overflow opening 62 to the collector 60. The collector 60 is provided with the insert 66, which has the sealing lip 68, so that the fluid flows from the overflow opening 62 through the insert 66 to the overflow opening 63 and from there the collector 60 into the collector 59 and from there through the overflow opening 64 from the collector 59. The opening 67 is in the Fig. 4 closed by the closure 70.

Die Fig. 5 zeigt ein weiteres Ausführungsbeispiel der Erfindung, bei welchem der Kondensator 80 mit dem Rohr-Rippenblock 81 ausgebildet ist. Die beiden Sammelrohre 82, 83 entsprechen im Wesentlichen den Sammelrohren 57 und 58 der Fig. 2. Im Ausführungsbeispiel der Fig. 5 sind die beiden Sammler 84, 85 jedoch nicht benachbart dem einströmseitigen Sammelrohr 58 gemäß Fig. 2, sondern benachbart dem ausströmseitigen Sammelrohr 83 der Fig. 5 angeordnet. Die Durchströmung des Rohr-Rippenblocks 81 erfolgt bis zum Sammler in drei Fluten 86, 87, 88. Das Fluid strömt dann durch den Sammler 84 und in den Sammler 85 und von dort zurück über den Sammler 84 in die Flut 89. Es strömt anschließend durch die Flut 90 zum Auslass 91 des Kondensators 80.The Fig. 5 shows another embodiment of the invention, in which the capacitor 80 is formed with the tube-fin block 81. The two manifolds 82, 83 substantially correspond to the manifolds 57 and 58 of the Fig. 2 , In the embodiment of Fig. 5 however, the two collectors 84, 85 are not adjacent the inflow-side manifold 58 according to Fig. 2 but adjacent to the outflow-side header 83 of the Fig. 5 arranged. The flow through the tube-fin block 81 takes place to the collector in three floods 86, 87, 88. The fluid then flows through the collector 84 and into the collector 85 and from there via the collector 84 in the flood 89. It then flows through the flood 90 to the outlet 91 of the capacitor 80th

Die Anordnung der beiden Sammler 84, 85 kann entsprechend der Fig. 4 ausgebildet sein, so dass im Sammler 84 eine Scheibe zur Trennung der Überströmöffnungen vorgesehen ist, wobei im Sammler 85 vorteilhaft ein Filter und/oder Trockner vorgesehen ist, der durch eine Einführöffnung, welche mittels eines Verschlusses verschließbar ist, befüllt werden kann.The arrangement of the two collectors 84, 85 may according to the Fig. 4 be formed so that a disc for separating the overflow openings is provided in the collector 84, wherein in the collector 85 advantageously a filter and / or dryer is provided, which can be filled by an insertion, which can be closed by means of a closure.

Die Fig. 6 bis 8 zeigen schematische Anordnungen von Kondensatoren mit einer Mehrzahl von Fluten und beiderseits des Rohr-Rippenblocks angeordneten Sammelrohren, wobei weiterhin jeweils zwei Sammler vorgesehen sind.The Fig. 6 to 8 show schematic arrangements of capacitors with a plurality of floods and arranged on both sides of the tube-fin block manifolds, each further comprising two collectors are provided.

Die Fig. 6 zeigt einen Kondensator 100 mit den Sammelrohren 101 und 102 und den Sammlern 103 und 104. Zwischen den beiden Sammelrohren 101 und 102 ist der Rohr-Rippenblock 105 angeordnet. Das Fluid, wie beispielsweise Kältemittel, strömt gemäß Pfeil 106 in das Sammelrohr 101 und durchströmt eine erste Flut 107 zum Sammelrohr 102. Dort wird das Fluid umgelenkt und durchströmt die Flut 108 zum Sammelrohr 101, wo es erneut umgelenkt wird, um in der Flut 109 zum Sammelrohr 102 zu strömen, von wo es durch eine Überströmöffnung 110 in den Sammler 103 tritt. Im Sammler 103 ist weiterhin eine Scheibe 111 vorgesehen, so dass das Fluid durch die Überströmöffnung 112 in den Sammler 104 tritt, wo auch der Filter-Trockner-Einsatz 113 vorgesehen ist. Anschließend durchströmt das Fluid die Überströmöffnung 114 zum Sammler 104 und die Überströmöffnung 115 zum Sammelrohr 103, so dass das Fluid durch die Flut 116 zum Sammelrohr 101 strömt und von dort durch gemäß dem Pfeil 117 den Kondensator verlässt. Die Fluten 107, 108 und 109 liegen in Strömungsrichtung vor den beiden Sammlern 103, 104 und sind als Enthitzungs- und Kondensierzonen vorgesehen, wobei die Flut 116 nach den beiden Sammlern 103, 104 angeordnet ist und eine Unterkühlstrecke für das Fluid darstellt.The Fig. 6 shows a condenser 100 with the headers 101 and 102 and the collectors 103 and 104. Between the two headers 101 and 102 of the tube-fin block 105 is arranged. The fluid, such as refrigerant flows according to arrow 106 in the manifold 101 and flows through a first flow 107 to the manifold 102. There, the fluid is deflected and flows through the flood 108 to the manifold 101, where it is deflected again to flow in the flood 109th to flow to the manifold 102, from where it passes through an overflow opening 110 into the collector 103. In the collector 103, a disc 111 is further provided, so that the fluid passes through the overflow opening 112 into the collector 104, where the filter-dryer insert 113 is provided. Subsequently, the fluid flows through the overflow opening 114 to the collector 104 and the overflow opening 115 to the manifold 103, so that the fluid flows through the flood 116 to the manifold 101 and from there through the arrow 117 leaves the condenser. The floods 107, 108 and 109 lie in the flow direction in front of the two collectors 103, 104 and are as Desuperheating and Kondensierzonen provided, the flood 116 is disposed after the two collectors 103, 104 and is a subcooling path for the fluid.

Die Fig. 7 stellt eine weitere schematische Darstellung eines Kondensators 130 dar, welcher zwei Sammelrohre 131 und 132 sowie zwei Sammler 133, 134 aufweist. Zwischen den beiden Sammelrohren 131 und 132 ist der Rohr-Rippenblock 135 vorgesehen. Der Rohr-Rippenblock 135 ist in sechs Fluten 136 bis 141 aufgeteilt. Dabei sind drei Enthitzungs- und Kondensierzonen als Fluten 136 bis 138 ausgebildet. Von dort strömt das Fluid durch das Sammelrohr 132 in den Sammler 133 und durch die Flut 139 als erste Unterkühlstrecke zum Sammelrohr 131 und in den Sammler 134 und von dort zurück zum Sammelrohr 131 durch die Flut 140 zum Sammelrohr 132 und von dort durch die Flut 141 zum Sammelrohr 131 zurück, von wo das Fluid aus dem Kondensator austritt. Zwischen den beiden Sammlern 133, 134 ist eine Flut 139 als Unterkühlstrecke vorgesehen. Nach dem Sammler 134 sind zwei Fluten 140, 141 als Unterkühlstrecke vorgesehen.The Fig. 7 FIG. 12 illustrates another schematic representation of a capacitor 130 having two manifolds 131 and 132 and two collectors 133, 134. Between the two headers 131 and 132, the tube-rib block 135 is provided. The tube fin block 135 is divided into six floods 136 to 141. In this case, three de-icing and condensing zones are formed as floods 136 to 138. From there, the fluid flows through the manifold 132 into the collector 133 and through the flood 139 as a first subcooling to the manifold 131 and the collector 134 and from there back to the manifold 131 through the flood 140 to the manifold 132 and from there through the flood 141st back to the manifold 131, from where the fluid exits the condenser. Between the two collectors 133, 134, a flood 139 is provided as subcooling. After the collector 134, two floods 140, 141 are provided as undercooling.

In Fig. 7 ist zu erkennen, dass der Sammler 133 zur Sammlung und Speicherung des Fluids dient, wobei im Sammler 134 auch der Filter-Trockner-Einsatz 142 angeordnet ist, so dass der Sammler 134 der Speicherung und auch der Filterung und/oder Trocknung des Fluids dient.In Fig. 7 It can be seen that the collector 133 is used for the collection and storage of the fluid, wherein in the collector 134 and the filter-dryer insert 142 is arranged so that the collector 134 is used for storing and also the filtering and / or drying of the fluid.

Die Fig. 8 zeigt ein weiteres alternatives Ausführungsbeispiel eines Kondensators 150 mit den Sammelrohren 151 und 152 beiderseits des Rohr-Rippenblocks 153.The Fig. 8 FIG. 12 shows another alternative embodiment of a condenser 150 with the headers 151 and 152 on either side of the tube fin block 153.

Die beiden Sammler 154 und 155 sind ähnlich der Anordnung der Fig. 6 neben dem Sammelrohr 152 angeordnet. Im Ausführungsbeispiel der Fig. 8 ist der Rohr-Rippenblock durch zwei Fluten 156, 157 gekennzeichnet. Dabei ist die Flut 156 die einlassseitige Flut, vom Einlass 158 bis zum Einlass in den Sammler 154 mittels der Überströmöffnung 159 und die Flut 157 ist die Flut, welche als Unterkühlstrecke zwischen der Überströmöffnung 160 und dem Auslass 161 des Kondensators angeordnet ist.The two collectors 154 and 155 are similar to the arrangement of Fig. 6 arranged next to the manifold 152. In the embodiment of Fig. 8 the tube-fin block is characterized by two floods 156, 157. In this case, the flood 156 is the inlet-side flood, from the inlet 158 to the inlet to the collector 154 by means of the overflow opening 159 and the flood 157 is the flood, which is arranged as a sub-cooling distance between the overflow 160 and the outlet 161 of the capacitor.

Die Flutigkeit des ersten Ausführungsbeispiels gemäß Fig. 1 ist dabei vorteilhaft 18 - 7 - 4 = 3 - 3, dies bedeutet, dass in der ersten Flut achtzehn Rohre parallel geschaltet sind, in der zweiten Flut sieben Rohre parallel geschaltet sind und in der dritten Flut vier Rohre parallel geschaltet sind, wobei nach dem ersten Sammler die Flut drei Rohre parallel geschaltet aufweist und nach dem zweiten Sammler die Flut ebenso drei Rohre parallel geschaltet aufweist.The flooding of the first embodiment according to Fig. 1 is advantageous 18 - 7 - 4 = 3 - 3, this means that in the first flood eighteen tubes are connected in parallel, in the second flood seven tubes are connected in parallel and in the third flood four tubes are connected in parallel, wherein after first collector has the flood three pipes connected in parallel and after the second collector the flood also has three pipes connected in parallel.

Das Volumen des Sammlers beträgt etwa 280 ml beim Durchmesser von ca. 36 mm, wobei das Trocknervolumen als reduzierendes Volumen bezüglich des Fluidaufnahmeraums berücksichtigt wurde. Bei einem Durchmesser von 45 mm würde ein Volumen von ca. 530 ml resultieren. Das Ausführungsbeispiel der Fig. 2 weist eine Flutigkeit auf, die 17 - 6 - 4 - 4 = 4 beträgt, das bedeutet, dass vor der Einströmung in den Sammler vier Fluten mit einmal siebzehn parallelen Rohren, einmal sechs parallelen Rohren und zweimal vier parallelen Rohren vorgesehen sind, wobei als Unterkühlstrecke nach dem Sammler eine Flut mit vier parallelen Rohren angeordnet ist. Das Volumen des Sammlers gemäß Fig. 2 entspricht etwa den Vorschlägen für das Volumen gemäß Fig. 1.The volume of the collector is about 280 ml at a diameter of about 36 mm, the volume of the dryer being taken into account as a reducing volume with respect to the fluid receiving space. With a diameter of 45 mm, a volume of approximately 530 ml would result. The embodiment of Fig. 2 has a volatility which is 17-6-4-4 = 4, that is to say before the inflow into the collector there are four floods with once seventeen parallel tubes, once six parallel tubes and two times four parallel tubes, with subcooling after the collector a flood with four parallel tubes is arranged. The volume of the collector according to Fig. 2 corresponds approximately to the proposals for the volume according to Fig. 1 ,

Das Ausführungsbeispiel gemäß Fig. 5 entspricht in seiner Flutigkeit dem Ausführungsbeispiel der Fig. 2, wobei lediglich der Sammler an dem anderen gegenüberliegenden Sammelrohr angeordnet ist.The embodiment according to Fig. 5 corresponds in its fluency to the embodiment of Fig. 2 wherein only the collector is disposed on the other opposite header.

In den Ausführungsbeispielen mit zwei nebeneinander angeordneten Sammlern ist der Trockner oder die Filter-Trockner-Kartusche oder der diesbezügliche Einsatz als Filter und/oder Trockner in dem Sammler angeordnet, der dem Sammelrohr am entferntesten ist. Dies ist auch vorteilhaft, wenn ein Austritts- oder Eintrittsflansch oder Stutzen vorgesehen ist, welcher dann unterhalb des Sammlers oder oberhalb des Sammlers angeordnet ist, der dem Sammelrohr am nächsten liegt. Dadurch wird eine bessere Austauschbarkeit des Einsatzes bzw. der Kartusche bewirkt.In the embodiments with two collectors arranged side by side, the dryer or the filter-dryer cartridge or the related use is arranged as a filter and / or dryer in the collector, which is farthest to the manifold. This is also advantageous if an outlet or inlet flange or nozzle is provided, which is then arranged below the collector or above the collector, which is closest to the manifold. This causes a better interchangeability of the insert or the cartridge.

Die Anordnung zweier einzelner Sammler bewirkt, dass gegenüber einem einzigen vorgesehenen Sammler die Durchmesser der beiden Sammler deutlich geringer gehalten werden können, als im Vergleich zu einem einzelnen Sammler mit gleichem Volumen. Dies reduziert den Bauraum in Fahrtrichtung, da die beiden Sammler nicht so große Durchmesser aufweisen müssen. Dabei sind die Sammler vorteilhaft derart angeordnet, dass ihre Mittelachsen auf einer Ebene liegen, wobei diese Ebene vorteilhaft eine Ebene ist, die durch den Rohr-Rippenblock des Kondensators verläuft.The arrangement of two individual collectors causes, compared to a single intended collector, the diameter of the two collectors kept significantly lower can be compared to a single collector of the same volume. This reduces the installation space in the direction of travel, since the two collectors do not have to have such large diameters. In this case, the collectors are advantageously arranged such that their central axes lie on a plane, this plane advantageously being a plane which runs through the tube-fin block of the capacitor.

Das Ausführungsbeispiel der Fig. 1, bei welchem zwei Sammler an jeweils einem Sammelrohr und benachbart zu diesem angeordnet sind, weist den Vorteil auf, dass wenige Schnittstellen zwischen den Sammlern und den Sammelrohren vorliegen, so dass diesbezüglich mit reduzierten Leckagen gerechnet werden kann. Durch die Erhöhung des Füllvolumens können auch Befülltoleranzen weniger starken Einfluss nehmen, da übliche Befülltoleranzen von ± 15 g gering sind im Vergleich zu einem Volumen von ca. 500 g Füllmenge für die beiden Sammler. Dadurch ergibt sich eine gleichbleibende Leistung als Funktion der Füllmenge und die Plateaulänge in dem bereits oben ausgeführten Temperatur-Füllmengen-Diagramm nimmt deutlich zu, was einer stabileren Klimatisierung dient, da die Unterkühlung über weite Befüll- und somit Betriebsbereiche stabil ist.The embodiment of Fig. 1 , in which two collectors are arranged on a respective collecting pipe and adjacent to this, has the advantage that there are few interfaces between the collectors and the headers, so that in this regard can be expected with reduced leakage. By increasing the filling volume, filling tolerances can also have less influence, since usual filling tolerances of ± 15 g are small in comparison to a volume of approx. 500 g filling quantity for the two collectors. This results in a constant performance as a function of the filling quantity and the plateau length in the temperature-filling-quantity diagram already described above increases significantly, which serves for a more stable air-conditioning, since the supercooling over wide filling and thus operating ranges is stable.

Auch ist es vorteilhaft, das Volumen der Sammler zu vergrößern, so dass mehr Kältemittel bevorratbar ist, so dass auch unter Volllast mehr Kältemittel im Kondensator zur Verfügung steht.It is also advantageous to increase the volume of the collector, so that more refrigerant can be stored, so that more refrigerant is available in the condenser even under full load.

Die Anordnung der beiden Sammler auf gegenüberliegenden Seiten des Rohr-Rippenblocks, siehe Figuren 1 und 7, bewirkt auch eine bessere Massenverteilung im Hinblick auf Vibrationen im Fahrzeug, da die Massen gleichmäßiger verteilt sind. Auch hinsichtlich des Lötprozesses in der Fertigung ist die bessere Verteilung der Massen des Kondensators vorteilhaft, da dadurch eine schnellere und gleichmäßigere Aufheizung im Lötprozess erzielbar ist.The arrangement of the two collectors on opposite sides of the tube-fin block, see FIGS. 1 and 7 , also causes a better mass distribution with regard to vibrations in the vehicle, since the masses are distributed more evenly. Also with regard to the soldering process in production, the better distribution of the masses of the capacitor is advantageous, as a faster and more uniform heating in the soldering process can be achieved.
