Durch die erfindungsgemäße Verteilung der Übertrittsöffnungen in dem der Austrittsöffnung gegenüberliegenden Längsabschnitt des Längskammerpartners kann die Temperaturverteilung auf der Austrittsseite des äußeren Mediums in besonders vorteilhafter Weise gezielt beeinflusst werden.The object is achieved with a heat exchanger described above in that the longitudinal chamber partner of the longitudinal chamber, in which the outlet opening is arranged, is delimited by a longitudinal dividing wall which has fewer crossing openings in a longitudinal section opposite the outlet opening than in the remaining region of the longitudinal dividing wall. The outlet opening can be provided laterally, that is to say in a narrow side, or in a longitudinal side of the longitudinal chamber. By the inventive distribution of the transfer openings in the outlet opening opposite longitudinal section of the longitudinal chamber partner, the temperature distribution on the outlet side of the outer medium can be selectively influenced in a particularly advantageous manner.

Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauschers ist dadurch gekennzeichnet, dass der Längskammerpartner der Längskammer, in welcher die Austrittsöffnung angeordnet ist, von einer Längstrennwand begrenzt wird, die in dem der Austrittsöffnung gegenüberliegenden Längsabschnitt kleinere Übertrittsöffnungen aufweist als in dem übrigen Bereich der Längstrennwand. Über die Größe des Durchtrittsquerschnitts der Übertrittsöffnungen kann das Temperaturprofil auf der Austrittsseite des äußeren Mediums in ein vorgegebenes Temperaturprofil angeglichen werden.A further preferred exemplary embodiment of the heat exchanger is characterized in that the longitudinal chamber partner of the longitudinal chamber in which the outlet opening is arranged is delimited by a longitudinal dividing wall which has smaller transfer openings in the longitudinal section opposite the outlet opening than in the remaining region of the longitudinal dividing wall. The size of the passage cross section of the transfer openings, the temperature profile on the outlet side of the outer medium can be adjusted to a predetermined temperature profile.

Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauschers ist dadurch gekennzeichnet, dass der Längskammerpartner der Längskammer, in welcher die Austrittsöffnung angeordnet ist, von einer Längstrennwand begrenzt wird, die in dem der Austrittsöffnung gegenüberliegenden Längsabschnitt keine Übertrittsöffnungen aufweist. Durch diese Maßnahme können extreme Temperaturen in dem der Eintrittsöffnung gegenüberliegenden Längsabschnitt wirksam verhindert werden.Another preferred exemplary embodiment of the heat exchanger is characterized in that the longitudinal chamber partner of the longitudinal chamber in which the outlet opening is arranged is delimited by a longitudinal dividing wall which has no transfer openings in the longitudinal section opposite the outlet opening. By this measure, extreme temperatures in the longitudinal section opposite the inlet opening can be effectively prevented.

Die oben angegebene Aufgabe ist bei einem vorab beschriebenen Wärmetauscher mit einer Längskammer, die in Längsrichtung durch eine Quertrennwand begrenzt ist, in der eine Durchtrittsöffnung vorgesehen ist, dadurch gelöst, dass der Längskammerpartner der Längskammer, in welcher die Durchtrittsöffnung angeordnet ist, von einer Längstrennwand begrenzt wird, die in einem der Durchtrittsöffnung gegenüberliegenden Längsabschnitt weniger Übertrittsöffnungen aufweist als in dem übrigen Bereich der Längstrennwand. Die Durchtrittsöffnung kann seitlich, das heißt in einer Schmalseite, oder in einer Längsseite der Längskammer vorgesehen sein. Durch die erfindungsgemäße Verteilung der Übertrittsöffnungen in dem der Durchtrittsöffnung gegenüberliegenden Längsabschnitt des Längskammerpartners kann die Temperaturverteilung auf der Austrittsseite des äußeren Mediums in besonders vorteilhafter Weise gezielt beeinflusst werden.The above object is achieved in a heat exchanger described above with a longitudinal chamber which is delimited in the longitudinal direction by a transverse partition in which a passage opening is provided, characterized in that the Längskammerpartner the longitudinal chamber in which the passage opening is arranged delimited by a longitudinal partition is, which has in one of the passage opening opposite longitudinal section fewer transfer openings than in the remaining region of the longitudinal partition wall. The passage opening may be provided laterally, that is to say in a narrow side, or in a longitudinal side of the longitudinal chamber. As a result of the distribution according to the invention of the transfer openings in the longitudinal section of the longitudinal chamber partner opposite the passage opening, the temperature distribution on the outlet side of the outer medium can be influenced in a particularly advantageous manner.

Die Durchtrittsöffnung in der Quertrennwand kann im Rahmen der vorliegenden Erfindung auch dadurch gegeben sein, dass die Quertrennwand gänzlich entfällt, wobei dann vorzugsweise der Längskammerpartner von einer Quertrennwand auf dem Niveau - in Längsrichtung gesehen - der entfallenen Quertrennwand begrenzt wird.The passage opening in the transverse partition wall can also be given in the context of the present invention in that the transverse partition completely eliminated, in which case preferably the Längskammerpartner of a transverse partition on the level - seen in the longitudinal direction - the omitted transverse partition is limited.

Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauschers ist dadurch gekennzeichnet, dass der Längskammerpartner der Längskammer, in welcher die Durchtrittsöffnung angeordnet ist, von einer Längstrennwand begrenzt wird, die in dem der Durchtrittsöffnung gegenüberliegenden Längsabschnitt kleinere Übertrittsöffnungen aufweist als in dem übrigen Bereich der Längstrennwand. Über die Größe des Durchtrittsquerschnitts der Übertrittsöffnungen kann das Temperaturprofil auf der Austrittsseite des äußeren Mediums in ein vorgegebenes Temperaturprofil angeglichen werden.A further preferred exemplary embodiment of the heat exchanger is characterized in that the longitudinal chamber partner of the longitudinal chamber in which the passage opening is arranged is delimited by a longitudinal dividing wall which has smaller transfer openings in the longitudinal section opposite the passage opening than in the remaining region of the longitudinal dividing wall. The size of the passage cross section of the transfer openings, the temperature profile on the outlet side of the outer medium can be adjusted to a predetermined temperature profile.

Ein weiteres bevorzugtes Ausführungsbeispiel des Wärmetauschers ist dadurch gekennzeichnet, dass der Längskammerpartner der Längskammer, in welcher die Durchtrittsöffnung angeordnet ist, von einer Längstrennwand begrenzt wird, die in dem der Durchtrittsöffnung gegenüberliegenden Längsabschnitt keine Übertrittsöffnungen aufweist. Durch diese Maßnahme können extreme Temperaturen in dem der Eintrittsöffnung gegenüberliegenden Längsabschnitt wirksam verhindert werden.A further preferred exemplary embodiment of the heat exchanger is characterized in that the longitudinal chamber partner of the longitudinal chamber in which the passage opening is arranged is delimited by a longitudinal dividing wall which has no transfer openings in the longitudinal section opposite the passage opening. By this measure, extreme temperatures in the longitudinal section opposite the inlet opening can be effectively prevented.

Bei herkömmlichen Wärmetauschern sind die Übertrittsöffnungen in der Längstrennwand gleichmäßig verteilt angeordnet. Durch die erfindungsgemäße Verteilung der Übertrittsöffnungen in der Längstrennwand wird sichergestellt, dass die der die Eintrittsöffnung, die Austrittsöffnung oder die Durchtrittsöffnung aufweisenden Flut in Strömungsrichtung nachfolgende Flut ausreichend und gleichmäßig mit Kältemittel versorgt wird.In conventional heat exchangers, the transfer openings are arranged distributed uniformly in the longitudinal partition wall. The distribution according to the invention of the transfer openings in the longitudinal dividing wall ensures that the tide having the inlet opening, the outlet opening or the passage opening in the direction of flow is sufficiently and evenly supplied with refrigerant.

Durch die gezielte Einflussnahme auf die Verteilung der Übertrittsöffnungen in der Längstrennwand kann der Wärmetauscher so ausgelegt werden, dass er auf der Austrittsseite des äußeren Mediums ein homogenes Temperaturprofil aufweist. Es ist aber auch möglich, das Temperaturprofil auf der Austrittsseite des äußeren Mediums an das Temperaturprofil eines existierenden Wärmetauschers anzupassen. Zu diesem Zweck kann das Temperaturprofil des existierenden Wärmetauschers zum Beispiel mit Hilfe von Temperaturfühlem oder thermographisch erfasst werden. Bei der Auslegung des Wärmetauschers, insbesondere der Längstrennwände, können dann gezielt kältere oder wärmere Zonen eingestellt werden. Dort, wo kein Übertritt vorhanden ist, wird es eher wärmer und umgekehrt.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung verschiedene Ausführungsbeispiele im Einzelnen beschrieben sind. Dabei können die in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein. Es zeigen:

By deliberately influencing the distribution of the transfer openings in the longitudinal partition wall of the heat exchanger can be designed so that it has a homogeneous temperature profile on the outlet side of the outer medium. But it is also possible, the temperature profile on the outlet side of the outer medium to the temperature profile of an existing Heat exchanger to adapt. For this purpose, the temperature profile of the existing heat exchanger can be detected, for example, by means of temperature sensors or thermographically. When designing the heat exchanger, in particular the longitudinal partitions, then colder or warmer zones can be set specifically. Where there is no crossing, it gets warmer and vice versa.

Figur 1 zeigt einen Flachrohr-verdampfer 1 in schematischer, perspektivischer Darstellung. Der Flachrohr-Verdampfer 1 umfasst einen Verdampferblock 3, der eine Vielzahl von (nicht dargestellten) Flachrohren aufweist, zwischen denen Wellrippen angeordnet sind. Der Aufbau und die Funktion eines derartigen Flachrohrverdampfers werden als bekannt vorausgesetzt und sind zum Beispiel in der deutschen Offenlegungsschrift DE 103 12 780 A1 beschrieben. FIG. 1 shows a flat tube evaporator 1 in a schematic, perspective view. The flat tube evaporator 1 comprises an evaporator block 3, which has a multiplicity of flat tubes (not shown), between which corrugated ribs are arranged. The structure and function of such a flat tube evaporator are assumed to be known and are for example in the German patent application DE 103 12 780 A1 described.

Der Verdampferblock 3 wird oben und unten von Sammelkästen 5, 6 begrenzt, die jeweils in Längskammem 8, 9; 11,12 unterteilt sind. Der Verdampferblock 3 ist seitlich durch Seitenteile 15, 16 abgeschlossen, welche die einen Seiten, wie beispielsweise die Schmalseiten, bilden. Die anderen Seiten, beispielsweise die Längsseiten, sind in Figur 1 mit 18 und 19 bezeichnet. Die Längsseite 18 entspricht der Lufteintrittsseite. Die Teile des Verdampferblocks 3 sowie die Sammelkästen 5 und 6 sind vorzugsweise aus Aluminium oder aus einer Aluminiumlegierung hergestellt und werden vorzugsweise miteinander verlötet, wobei die Enden der Flachrohre dicht oder abgedichtet in Öffnungen in den Sammelkästen 5, 6 aufgenommen sind. Die zwischen den Flachrohren angeordneten Rippen werden von Luft in der durch Pfeile 21 bis 23 angedeuteten Strömungsrichtung überströmt.The evaporator block 3 is bounded above and below by collecting tanks 5, 6, each in Längskammem 8, 9; 11,12 are divided. The evaporator block 3 is laterally closed by side parts 15, 16, which form the one side, such as the narrow sides. The others Pages, such as the long sides, are in FIG. 1 denoted by 18 and 19. The longitudinal side 18 corresponds to the air inlet side. The parts of the evaporator block 3 and the manifolds 5 and 6 are preferably made of aluminum or an aluminum alloy and are preferably soldered together, the ends of the flat tubes are sealed or sealed in openings in the manifolds 5, 6 are added. The ribs arranged between the flat tubes are overflowed by air in the direction of flow indicated by arrows 21 to 23.

Die Längskammer 8 erstreckt sich über die gesamte Breite des Wärmetauschers 1. Die Längskammer 9 ist durch eine Quertrennwand 25 in zwei Längskammem 26 und 27 unterteilt. In der Längskammer 26 ist eine Eintrittsöffnung 29 vorgesehen, durch die ein Kältemittel, zum Beispiel R134a in den Verdampfer 1 gelangt. In der Längskammer 27 ist eine Austrittsöffnung 30 vorgesehen, durch welche das Kältemittel aus dem Wärmetauscher 1 austritt. Die der Längskammer 8 gegenüberliegende Längskammer 11 ist durch eine Quertrennwand 32 in zwei Längskammem 34 und 35 unterteilt. Die der Längskammer 9 gegenüberliegende Längskammer 12 ist durch eine Quertrennwand 37 in zwei Längskammem 39, 40 unterteilt.The longitudinal chamber 8 extends over the entire width of the heat exchanger 1. The longitudinal chamber 9 is divided by a transverse partition 25 in two Längskammem 26 and 27. In the longitudinal chamber 26, an inlet opening 29 is provided, through which a refrigerant, for example R134a, enters the evaporator 1. In the longitudinal chamber 27, an outlet opening 30 is provided through which the refrigerant exits the heat exchanger 1. The longitudinal chamber 11 opposite the longitudinal chamber 8 is divided by a transverse dividing wall 32 into two longitudinal chambers 34 and 35. The longitudinal chamber 12 opposite the longitudinal chamber 12 is divided by a transverse partition wall 37 into two longitudinal chambers 39, 40.

Das Kältemittel wird, wie durch einen Pfeil 41 angedeutet ist, der vorderen, das heißt luvseitigen Längskammer 26 durch eine (nicht dargestellte) Druckleitung zugeführt. Das Kältemittel kann auch der luvseitigen Längskammer 27 und der leeseitigen Längskammer 8 zugeführt werden. Zuvor wird das Kältemittel in einem (nicht dargestellten) Expansionsventil auf den Verdampferdruck reduziert, das heißt, das Kältemittel tritt als Kältemittelnassdampf in die Längskammer 26 ein. Nach Durchströmung des Verdampfers 1 -was im Folgenden genauer erläutert wird- wird das Kältemittel über eine (nicht dargestellte) Saugleitung abgesaugt. In Luftströmungsrichtung 21 bis 23 vor dem Verdampfer 1 beziehungsweise dem Verdampferblock 3 ist ein (nicht dargestelltes) Expansionsventil angeordnet.The refrigerant is, as indicated by an arrow 41, the front, that is windward longitudinal chamber 26 fed through a (not shown) pressure line. The refrigerant can also be supplied to the windward longitudinal chamber 27 and the leeward longitudinal chamber 8. Previously, the refrigerant in an expansion valve (not shown) is reduced to the evaporator pressure, that is, the refrigerant enters the longitudinal chamber 26 as the refrigerant wet steam. After flowing through the evaporator 1, which is explained in more detail below, the refrigerant is sucked off via a suction line (not shown). In the air flow direction 21 to 23 in front of the evaporator 1 and the evaporator block 3, an (not shown) expansion valve is arranged.

Der in Figur 1 dargestellte Wärmetauscher 1, der auch als Verdampfer bezeichnet wird, wird in Richtung von Pfeilen 41 bis 49 von Kältemittel durchströmt. Die Pfeile 42, 44, 46, 48 stellen jeweils eine Flut von Strömungskanälen dar. Der Wärmetauscher 1 wird daher auch als vierflutig bezeichnet. Der Pfeil 43 stellt einen Übertritt zwischen den Längskammem 39 und 34 in dem Sammelkasten 6 dar. Der Pfeil 47 stellt einen Übertritt zwischen den Längskammem 35 und 40 in dem Sammelkasten 6 dar. Die Übertritte 43 und 47 werden durch Übertrittsöffnungen ermöglicht, die in einer Trennwand vorgesehen sind, durch welche die Längskammem 34 und 39 sowie 35 und 40 voneinander getrennt sind.The in FIG. 1 illustrated heat exchanger 1, which is also referred to as an evaporator, is flowed through in the direction of arrows 41 to 49 of refrigerant. The arrows 42, 44, 46, 48 each provide a flood of flow channels The heat exchanger 1 is therefore also referred to as vierflutig. The arrow 43 represents a passage between the Längskammem 39 and 34 in the collecting box 6. The arrow 47 represents a transition between the Längskammem 35 and 40 in the collecting box 6. The Übertrritte 43 and 47 are made possible by transfer openings in a partition are provided, through which the Längskammem 34 and 39 and 35 and 40 are separated from each other.

In den Figuren 2 bis 4 ist jeweils die Ansicht eines Schnitts durch den Sammelkasten 6 aus Figur 1 dargestellt. In der Schnittansicht der Figuren 2 bis 4 sieht man eine Längstrennwand 51, die in Längsrichtung zwischen der Längskammer 34 und der Längskammer 39 in dem Sammelkasten 6 angeordnet ist. Außerdem sieht man in der Schnittansicht eine Längstrennwand 52, die zwischen den Längskammern 35 und 40 angeordnet ist. Zwischen den Längstrennwänden 51, 52 sind die Quertrennwände 32, 37 angeordnet. Die Längstrennwände 51, 52 sind vorzugsweise einstückig miteinander verbunden.In the FIGS. 2 to 4 is in each case the view of a section through the collecting box 6 FIG. 1 shown. In the sectional view of FIGS. 2 to 4 one sees a longitudinal partition wall 51, which is arranged in the longitudinal direction between the longitudinal chamber 34 and the longitudinal chamber 39 in the collecting box 6. In addition, one sees in the sectional view of a longitudinal partition wall 52 which is arranged between the longitudinal chambers 35 and 40. Between the longitudinal partitions 51, 52, the transverse partitions 32, 37 are arranged. The longitudinal partition walls 51, 52 are preferably integrally connected to each other.

Der in Figur 2 dargestellte Sammelkasten 6 weist in einem der Eintrittsöffnung (29 in Figur 1) gegenüberliegenden Bereich einen Längsabschnitt 54 auf, in dem keine Übertrittsöffnungen vorgesehen sind. Zwischen dem Längsabschnitt 54 und den Quertrennwänden 32, 37 sind in der Längstrennwand 51 vier Übertrittsöffnungen 56 bis 59 ausgespart, welche die Gestalt von Langlöchem aufweisen.The in FIG. 2 illustrated collection box 6 has in one of the inlet opening (29 in FIG. 1 ) opposite region on a longitudinal portion 54 in which no transfer openings are provided. Between the longitudinal section 54 and the transverse partition walls 32, 37, four transfer openings 56 to 59 are recessed in the longitudinal partition wall 51, which have the shape of elongated holes.

In der Längstrennwand 52 ist gegenüber der Austrittsöffnung (30 in Figur 1 ) ein Längsabschnitt 61 vorgesehen, in dem keine Übertrittsöffnungen angeordnet sind. Zwischen dem Längsabschnitt 61 und den Quertrennwänden 32, 37 sind in der Längstrennwand 52 zwei Übertrittsöffnungen 63 und 64 ausgespart. Zwischen dem Längsabschnitt 61 und der Seitenwand des Sammeikastens 6 sind in der Längstrennwand 52 drei Übertrittsöffnungen 66 bis 68 ausgespart. Die Übertrittsöffnung 68 hat einen kleineren Durchtrittsquerschnitt als die Übertrittsöffnungen 66 und 67.In the longitudinal partition 52 is opposite the outlet opening (30 in FIG. 1 ) A longitudinal portion 61 is provided in which no transfer openings are arranged. Between the longitudinal section 61 and the transverse partition walls 32, 37, two transfer openings 63 and 64 are recessed in the longitudinal partition 52. Between the longitudinal section 61 and the side wall of the Sammieikastens 6 52 three transfer openings 66 to 68 are recessed in the longitudinal partition wall. The transfer opening 68 has a smaller passage cross-section than the transfer openings 66 and 67.

Bei dem in Figur 3 dargestellten Ausführungsbeispiel ist der der Eintrittsöffnung (29 in Figur 1) gegenüberliegende Längsabschnitt 74 größer als bei dem in Figur 2 dargestellten Ausführungsbeispiel ausgebildet. Zwischen dem Längsabschnitt 74 und den Quertrennwänden 32, 37 sind in der Längstrennwand 51 drei Übertrittsöffnungen 77 bis 79 ausgespart. Der der Austrittsöffnung (30 in Figur 1) gegenüberliegende Längsabschnitt 81 ist bei dem in Figur 3 dargestellten Ausführungsbeispiel ebenfalls größer als bei dem in Figur 2 dargestellten Ausführungsbeispiel. Zwischen dem Längsabschnitt 81 und den Quertrennwänden 32, 37 ist nur eine Übertrittsöffnung 83 angeordnet. Zwischen dem Längsabschnitt 81 und der Seitenwand des Sammelkastens 6 sind zwei Übertrittsöffnungen 86, 87 ausgespart.At the in FIG. 3 illustrated embodiment of the inlet opening (29 in FIG. 1 ) opposite longitudinal portion 74 greater than in the FIG. 2 illustrated embodiment formed. Between the longitudinal section 74 and the transverse partition walls 32, 37, three transfer openings 77 to 79 are recessed in the longitudinal partition wall 51. The outlet opening (30 in FIG. 1 ) opposite longitudinal portion 81 is in the in FIG. 3 illustrated embodiment also larger than in the FIG. 2 illustrated embodiment. Between the longitudinal section 81 and the transverse partition walls 32, 37, only one crossing opening 83 is arranged. Between the longitudinal section 81 and the side wall of the collecting tank 6, two transfer openings 86, 87 are recessed.

Bei dem in Figur 4 dargestellten Ausführungsbeispiel sind zwischen einem der Eintrittsöffnung (29 in Figur 1) gegenüberliegenden Längsabschnitt 94 und den Quertrennwänden 32, 37 drei Übertrittsöffnungen 97 bis 99 ausgespart. Der Längsabschnitt 94 ist genauso groß wie der Längsabschnitt 54 bei dem in Figur 2 dargestellten Ausführungsbeispiel. Die Übertrittsöffnungen 97 bis 99 weisen einen größeren Durchtrittsquerchnitt auf als die Übertrittsöffnungen bei den vorangegangenen Ausführungsbeispielen. Die Längstrennwand 52 weist bei dem in Figur 4 dargestellten Ausführungsbeispiel gegenüber der Austrittsöffnung (30 in Figur 1) einen Längsabschnitt 101 auf, der größer als bei dem in Figur 2 dargestellten Ausführungsbeispiel, aber kleiner als bei dem in Figur 3 dargestellten Ausführungsbeispiel ist. Zwischen dem Längsabschnitt 101 und den Quertrennwänden 32, 37 ist eine Übertrittsöffnung 103 angeordnet, die einen größeren Durchtrittsquerschnitt als bei den vorangegangenen Ausführungsbeispielen aufweist. Zwischen dem Längsabschnitt 101 und der Seitenwand des Sammelkastens 6 sind zwei Übertrittsöffnungen 106, 107 angeordnet, die jeweils einen größeren Durchtrittsquerschnitt als bei den vorangegangenen Ausführungsbeispielen aufweisen.At the in FIG. 4 illustrated embodiment are between one of the inlet opening (29 in FIG. 1 ) opposed longitudinal section 94 and the transverse partition walls 32, 37 recessed three transfer openings 97 to 99. The longitudinal portion 94 is the same size as the longitudinal portion 54 in the in FIG. 2 illustrated embodiment.

Bei einem Verdampfer mit vier Strömungswegen und Anschlüssen in Luftrichtung gibt es zwei Übertrittszonen in der Tiefe, die zusammen die gesamte Verdampferbreite abdecken, so dass ein solcher Verdampfer hinsichtlich der freien Wählbarkeit des Temperaturprofils das Optimum darstellt. Bei dieser Schaltungsart ist es insbesondere im Bereich des zweiten Übertritts (47 in Figur 1) erforderlich, dass nur ein Teil der möglichen Übertritte ausgeführt wird, um ein günstiges Temperaturprofil zu erzielen.In an evaporator with four flow paths and connections in the direction of air there are two crossing zones in the depth, which together cover the entire evaporator width, so that such an evaporator is the optimum in terms of the free selectability of the temperature profile. In this type of circuit, it is particularly in the area of the second crossing (47 in FIG. 1 ) requires that only part of the possible crossovers be carried out in order to achieve a favorable temperature profile.

Figur 5 zeigt einen Flachrohr-Verdampfer 118 mit einem seitlichen Kältemitteleinlass 119 und einem Längsanschluss 120 für den Austritt beziehungsweise die Absaugung des Kältemittels. Dieser Verdampfer 118 ist prinzipiell gleich wie der zuvor beschriebene Verdampfer 1 aufgebaut, er ist jedoch größer in der Längserstreckung und wird fünfflutig durchströmt, das heißt in fünf Passagen I, II, III, IV, V, wobei nach der Passage III eine Umlenkung in der Tiefe III/IV entgegen der Luftströmungsrichtung L erfolgt. Die Umlenkung in der Tiefe kann jedoch auch in der Luftströmungsrichtung erfolgen. Dies gilt allgemein, auch für die anderen Ausführungsbeispiele. FIG. 5 shows a flat tube evaporator 118 with a side refrigerant inlet 119 and a longitudinal port 120 for the outlet or the suction of the refrigerant. This evaporator 118 is in principle the same as the evaporator 1 described above, but it is larger in the longitudinal extent and flows through five-flow, that is, in five passages I, II, III, IV, V, wherein after the passage III, a deflection in the Depth III / IV against the air flow direction L takes place. However, the deflection in depth can also take place in the air flow direction. This applies in general, also for the other embodiments.

Der Verdampfer 118 weist einen oberen Sammelkasten 121 mit zwei Längskammem 121a, 121b und zwei quer angeordneten Trennwänden 122, 123 auf. Ein unterer Sammelkasten 124 weist zwei Längskammern 124a, 124b auf mit einer quer angeordneten Trennwand 150. Die Trennwände 122, 150 auf der Leeseite sind bezüglich der Längsausdehnung des Verdampfers versetzt angeordnet, um die dreiflutige Ausbildung zu gewährleisten. Auf der Luvseite ist die Trennwand 123 mittig des Verdampfers angeordnet. Dadurch werden auf der Luvseite zwei gleich verteilte Fluten erzeugt.The evaporator 118 has an upper header box 121 with two Längskammem 121 a, 121 b and two transverse partitions 122, 123. A lower header 124 has two longitudinal chambers 124a, 124b with a transverse partition 150. The divider walls 122, 150 on the leeward side are staggered with respect to the longitudinal extent of the evaporator to ensure three-flow formation. On the windward side, the partition wall 123 is arranged centrally of the evaporator. As a result, two equally distributed floods are generated on the windward side.

Aufgrund dieser Ausbildung der Sammelkästen 121, 124 mit Trennwänden 122, 123, 150 sowie seitlichem Anschluss 119 und Längsanschluss 120 ergibt sich die dargestellte fünfflutige Strömung. Auch hier kann je nach Betriebsbedingungen des Verdampfers vorteilhaft das Kältemittel in den Passagen I, II und III auf der Leeseite des Verdampfers 118 als Nassdampf mit (konstanter) Verdampfungstemperatur vorliegen, so dass sich auf der Luftaustrittsseite eine gleichmäßige Temperaturverteilung ergeben könnte. Wie erwähnt, soll das Kältemittel am Austritt 120 als überhitzter Dampf mit einer vorgegebenen Überhitzungstemperatur vorliegen; daher strömt in der letzten Passage V Kältemittel mit Überhitzungstemperatur, möglicherweise bereits in der vorletzten Passage IV -beide liegen jedoch auf der Lufteintrittsseite. Es ergibt sich somit -auch für einen fünfflutig ausgelegten Verdampfer eine gleichmäßige Temperaturverteilung auf der Luftaustrittsseite.Due to this design of the manifolds 121, 124 with partitions 122, 123, 150 and side port 119 and longitudinal port 120 results in the illustrated five-flow flow. Again, depending on the operating conditions of the evaporator advantageously the refrigerant in the passages I, II and III on the leeward side of the evaporator 118 as wet steam with (constant) evaporation temperature, so that could result in a uniform temperature distribution on the air outlet side. As mentioned, the refrigerant at outlet 120 should be in the form of superheated steam at a predetermined superheat temperature; therefore in the last passage V refrigerant with overheating temperature flows, possibly already in the penultimate passage IV -beide, however, are on the air inlet side. This results in a uniform temperature distribution on the air outlet side even for a five-flute evaporator.

Der Verdampfer ist auf der Leeseite und der Luvseite in verschiedene Bereiche geteilt, wie in verschiedene Fluten. Diese Bereiche sind auf der Leeseite und der Luvseite gemäß Darstellung nicht gleich groß. Dies führt dazu, dass die Blockverschaltung progressiv ist, das heißt, dass die erste Rohrreihe, in die das Kältemittel einströmt oder eingespritzt wird, sich in drei Bereiche und Fluten aufteilt (I, II, III), während die zweite Rohrreihe, aus welcher das Kältemittel abgesaugt wird, sich nur in zwei Bereiche oder Fluten (IV, V) aufteilt. Dies hat den Vorteil, dass das Gas mit zunehmender Verdampfung entsprechend expandieren kann und der dazu erforderliche Raum zur Verfügung gestellt wird.The evaporator is divided into different areas on the lee side and the windward side, as in different floods. These areas are not the same size on the lee side and the windward side as shown. As a result, the block interconnection is progressive, that is, the first row of tubes into which the refrigerant flows or is injected is divided into three areas and floods (I, II, III), while the second row of tubes, from which the one Refrigerant is sucked, divided into only two areas or floods (IV, V). This has the advantage that the gas can expand accordingly with increasing evaporation and the space required for this is made available.

Bei einem anderen AusFührungsbeispiel der Erfindung kann die Blockverschaltung bei einem fünfflutigen Verdampfer auch degressiv sein, das heißt, dass die erste Rohrreihe, in die das Kältemittel einströmt oder eingespritzt wird, in zwei Bereiche oder Fluten aufteilt (I, II), während die zweite Rohrreihe, aus welcher das Kältemittel abgesaugt wird, sich in drei Bereiche oder Fluten (III, IV, V) aufteilt.In another embodiment of the invention, the block interconnection in a five-flute evaporator may also be degressive, that is, the first row of tubes into which the refrigerant flows or is injected divides into two zones (I, II), while the second row of tubes from which the refrigerant is sucked, divided into three areas or floods (III, IV, V).

Bei dem Ausführungsbeispiel der Figur 5 ist der Einlass für das Kältemittel an einer unteren Längskammer angeordnet und der Ausgang an einem oberen Anschluss. Vorteilhaft sind die Anschlüsse jedoch auf der gleichen Seite des Verdampfers angeordnet, in Längsrichtung betrachtet. Bei einem anderen Ausführungsbeispiel können die Anschlüsse jedoch auch an gegenüberliegenden Seiten des Verdampfers in Längsrichtung betrachtet angeordnet werden.In the embodiment of the FIG. 5 the inlet for the refrigerant is arranged on a lower longitudinal chamber and the outlet on an upper connection. Advantageously, however, the connections are arranged on the same side of the evaporator, viewed in the longitudinal direction. However, in another embodiment, the ports may also be arranged on opposite sides of the evaporator in the longitudinal direction.

Bei dem Ausführungsbeispiel der Fig. 5 wird durch die Strömungspfadabschnitte III und IV ein Wärmetauscherblock gebildet, der durch Quertrennwände 122 und 123 begrenzt wird. Gegenüber den Quertrennwänden 122, 123 sind beispielsweise nicht dargestellte Quertrennwände mit Durchtrittsöffnungen angeordnet, die vorzugsweise, wie in Fig. 5 gezeigt, auch vollständig entfallen, um ein Überströmen von beziehungsweise zu einem benachbarten Wärmetauscherblock zu gewährleisten.In the embodiment of the Fig. 5 is formed by the flow path sections III and IV, a heat exchanger block, which is bounded by transverse partition walls 122 and 123. Opposite the transverse partition walls 122, 123, for example, transverse dividing walls, not shown, are arranged with passage openings, which preferably, as in Fig. 5 shown, also completely eliminated, to ensure an overflow from or to an adjacent heat exchanger block.

Bei dem Ausführungsbeispiel der Fig. 1 wird durch die vom Eintritt 41 aus gesehen ersten beiden Strömungspfadabschnitte ein Wärmetauscherblock gebildet, der durch die Quertrennwand 25 begrenzt wird. Gegenüber der Quertrennwand 25 entfällt ebenfalls eine fiktive Quertrennwand, so dass Kältemittel zu den beiden übrigen Stömungspfadabschnitten überströmen kann. In einem solchen Fall richtet sich die Größe und/oder Verteilung der Übertrittsöffnungen in einer die Längskammer 34 unterteilenden Längstrennwand entweder nach der Position des Eintritts 41 oder nach der Position der durch die entfallende Quertrennwand gegebene Überströmöffnung oder nach beiden Positionen.In the embodiment of the Fig. 1 is formed by the first two flow path sections seen from the entry 41 from a heat exchanger block, which is bounded by the transverse partition 25. Compared to the transverse partition wall 25 also eliminates a fictitious transverse partition, so that refrigerant can flow over to the other two Stömungspfadabschnitten. In such a case, the size and / or distribution of the transfer openings in a longitudinal partition dividing the longitudinal partition 34 depends either on the position of the inlet 41 or on the position of the given by the attributable transverse partition overflow or both positions.

Wenn unterschiedliche Eintritts-, Austritts- beziehungsweise Überströmöffnungen unterschiedliche Verteilungen der Übertrittsöffnungen in einer Längstrennwand zur Folge hätten, werden entweder beide Öffnungen berücksichtigt oder es wird einer dominanten Öffnung der Vorzug gegeben.If different inlet, outlet or overflow openings would result in different distributions of the transfer openings in a longitudinal dividing wall, either both openings are taken into account or preference is given to a dominant opening.
