Abstract

An evaporation heat exchanger has a evaporation structure flowed over by ambient air to which an evaporating liquid (condensate) can be supplied and which communicates with a medium to be cooled (coolant). The evaporation structure is designed as a folded fin (1). The folded fin has a number of parallel almost S-shaped folds (3) which form internal channels (5,6) and capillary gaps (10,11) for the liquid. The folded fins are stacked into a packet of fins (21) and are connected with tubes (23) for the medium to be cooled. The tubes are designed as round tubes and are fastened by mechanical expansion in girders of the folded ribs.

Description

Die Erfindung bezieht sich auf einen Verdunstungs-Wärmeübertrager mit einer von Umgebungsluft überströmten Verdunstungsstruktur, der eine ver­ dunstende Flüssigkeit (Kondenswasser) zuführbar ist und die wärmeleitend mit einem zu kühlenden Medium (Kältemittel) in Verbindung steht.The invention relates to an evaporative heat exchanger an evaporation structure overflowed with ambient air, which ver evaporating liquid (condensed water) can be supplied and the heat conductive is connected to a medium to be cooled (refrigerant).

Ein solcher Verdunstungs-Wärmeübertrager wurde durch die DE-A 196 13 684 der Anmelderin bekannt.Such an evaporative heat exchanger was described in DE-A 196 13 684 Applicant known.

Derartige Verdunstungs-Wärmeübertrager werden vorzugsweise für die Unterkühlung des Kältemittels von Kraftfahrzeugklimaanlagen eingesetzt, um den Wirkungsgrad der Klimaanlage zu verbessern. Der bekannte Ver­ dunstungs-Wärmeübertrager weist eine Verdunstungsstruktur auf, die durch auf der Oberfläche befindliche Verdunstungskanäle eines extrudierten Pro­ files angeordnet sind, welches gleichzeitig den Kanal für das zu unterküh­ lende Kältemittel bildet. Ein derartiger Verdunstungs-Wärmeübertrager ist relativ schwer und weist nur eine relativ geringe Verdunstungsoberfläche auf. Durch die DE-A 196 45 089 der Anmelderin wurde ein weiterer Verdun­ stungs-Wärmeübertrager bekannt, der durch eine Verdunstungsstruktur in Form eines Polyestergewebes gekennzeichnet ist. Auch diese Verdun­ stungsstruktur bietet eine zu geringe Verdunstungsoberfläche, um eine wirk­ same Unterkühlung des Kältemittel zu erzeugen.Such evaporation heat exchangers are preferably used for Subcooling of the refrigerant used in automotive air conditioning systems, to improve the efficiency of the air conditioning system. The well-known Ver Evaporation heat exchanger has an evaporation structure that by Evaporation channels of an extruded Pro located on the surface files are arranged, which is also the channel for the hypothermia coolant. Such an evaporative heat exchanger is relatively heavy and has only a relatively small evaporation surface on. Another Verdun was by DE-A 196 45 089 of the applicant Stungs heat exchanger known by an evaporation structure in Shape of a polyester fabric is marked. This Verdun too structure offers too little evaporation surface to be effective to produce the same supercooling of the refrigerant.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Verdunstungs- Wärmeübertrager mit einer vergrößerten Verdunstungsoberfläche zu schaf­ fen, und dies mit geringem Materialeinsatz in einer kompakten Bauweise.It is therefore an object of the present invention to provide an evaporation To create heat exchangers with an enlarged evaporation surface fen, and this with little material in a compact design.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst, d. h. die Verdunstungsstruktur wird durch eine Faltrippe gebildet, die aus ei­ nem relativ dünnen Metallblech durch "Plissieren" hergestellt ist. Dadurch werden einerseits die für die Kondenswasserzuführung notwendigen Kanäle gebildet und andererseits Kapillarspalte, durch welche das zugeführte Kon­ denswasser von innen nach außen austreten und in dem Luftstrom verdun­ sten kann. Somit wird auf engstem Raum mit geringem Gewichtsaufwand und Materialeinsatz eine Verdunstungsoberfläche zur Verfügung gestellt, die außerordentlich wirksam ist, d. h. eine hohe Verdunstungsleistung und damit eine effektive Unterkühlung für das Kältemittel erzielt.This object is achieved by the features of claim 1, i. H. the evaporation structure is formed by a folding rib made of egg nem relatively thin sheet metal is made by "pleating". Thereby become the channels necessary for the condensation water supply formed and on the other hand capillary gaps, through which the supplied Kon Discharge water from the inside out and evaporate in the air flow can. Thus, in a confined space with little weight and material use provided an evaporation surface that is extremely effective, d. H. a high evaporation rate and therefore effective supercooling for the refrigerant.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß eine solche Faltrippe zu einem Paket gestapelt ist und von Rundrohren, welche das Kältemittel führen, durchsetzt wird. Die Rundrohre können vorteilhafterweise durch mechanisches Aufweiten mit diesen Faltrippen verbunden und somit zu einem kompakten Wärmeübertrager ausgebildet werden.In a further embodiment of the invention it is provided that such Folding rib is stacked into a package and of round tubes, which the Lead refrigerant, is penetrated. The round tubes can advantageously connected to these folding ribs by mechanical expansion and thus be formed into a compact heat exchanger.

In weiterer Ausgestaltung der Erfindung ist an der Stirnseite des Rippenpa­ ketes ein Verteilerkasten angeordnet, über welchen das Kondenswasser zugeführt wird, welches vom Verdampfer der Klimaanlage abgezogen wird. Um eine Verschmutzung der engen Rippenkanäle und der Kapillaren zu vermeiden, ist in dem Verteilerkasten ein Filter zur Zurückhaltung von Schmutzpartikeln vorgesehen.In a further embodiment of the invention is on the end face of the rib pair ketes a distribution box arranged, over which the condensed water is supplied, which is withdrawn from the evaporator of the air conditioning system. To contaminate the narrow rib channels and the capillaries avoid, there is a filter in the distribution box for the retention of Dirt particles provided.

Schließlich ist in einer weiteren Ausgestaltung der Erfindung vorgesehen, den Verdunstungs-Wärmeübertrager, bestehend aus dem Paket von Faltrip­ pen und Rundrohren, mit dem Kondensator der Kraftfahrzeugklimaanlage zu integrieren, d. h. zu einer Baueinheit auszubilden, was den Vorteil hat, daß das Rippenpaket des Verdunstungs-Wärmeübertragers in gleicher Weise wie der Kondensator vom Luftstrom überstrichen wird, der durch das Kon­ densatorgebläse gefördert wird. Finally, in a further embodiment of the invention, the evaporative heat exchanger, consisting of the Faltrip package pen and round pipes, with the condenser of the automotive air conditioning system integrate, d. H. to form a unit, which has the advantage that the fin package of the evaporative heat exchanger in the same way how the condenser is swept by the air flow through the con condenser fan is promoted.  

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigenAn embodiment of the invention is shown in the drawing and is described in more detail below. Show it

Fig. 2, Fig. 2a, Fig. 2b den Verdunstungs-Wärmeübertrager mit Faltrippe und Kältemittelkondensator. Fig. 2, Fig. 2a, Fig. 2b, the evaporation heat exchanger with a rib and refrigerant condenser.

Fig. 1 zeigt eine Faltrippe 1, die aus einem Blechstreifen, vorzugsweise aus Aluminiumblech durch sogenanntes Plissieren hergestellt ist. Der Blech­ streifen 2 erhält durch das Plissieren einzelne Faltungen 3, die durch einen im Querschnitt S-förmigen Verlauf 4 gekennzeichnet sind. Durch diesen S- förmigen Verlauf wird einerseits ein oberer Kanal 5 und andererseits ein unterer Kanal 6 gebildet - hier wird also ein Hohlraum zwischen der oberen Blechstreifenpartie 7 und der mittleren Partie 8 belassen und ebenso zwi­ schen der mittleren Partie 8 und der unteren Partie 9. Hingegen liegen die einzelnen Faltungen in ihren äußeren Bereichen jeweils aneinander an, so daß Kapillarspalte 10 und 11 gebildet werden. Die einzelnen Faltungen 3 verlaufen jeweils parallel zueinander und bilden ein etwa ebenes Gebilde, welches in Richtung der Pfeile A von der Umgebungsluft überströmt wird. Die zu verdunstende Flüssigkeit dagegen wird in Richtung der Pfeile B zu­ geführt, durchströmt die einzelnen Kanäle 5 und 6 quer zur Luftströmungs­ richtung A und tritt durch die Kapillarspalte 10 und 11 nach außen in den Luftstrom. Fig. 1 shows a folding rib 1 , which is made of a sheet metal strip, preferably of aluminum sheet by so-called pleating. The sheet metal strip 2 receives by pleating individual folds 3 , which are characterized by a cross-section S-shaped course 4 . This S-shaped course on the one hand forms an upper channel 5 and on the other hand a lower channel 6 - here a cavity is left between the upper sheet metal strip section 7 and the central section 8 and also between the middle section 8 and the lower section 9 . In contrast, the individual folds each abut one another in their outer regions, so that capillary gaps 10 and 11 are formed. The individual folds 3 each run parallel to one another and form an approximately flat structure which is flowed over by the ambient air in the direction of the arrows A. The liquid to be evaporated, however, is guided in the direction of arrows B, flows through the individual channels 5 and 6 transversely to the air flow direction A and passes through the capillary gaps 10 and 11 to the outside into the air flow.

Fig. 2, 2a, 2b zeigen einen Verdunstungs-Wärmeübertrager 20 mit ei­ nem Rippenpaket 21, welches aus Faltrippen 21a gemäß Fig. 1 aufgebaut ist. Dabei verlaufen die einzelnen Faltungen 22 und die durch sie gebildeten Kanäle quer zu dem Luftstrom, der durch die Pfeile A gekennzeichnet ist. Die Rippen 21a des Rippenpaketes 21 sind derart aufeinander gestapelt, daß zwischen ihnen ein Luftspalt 21b belassen ist, durch den die Umge­ bungsluft strömt, so daß in diesem Luftstrom eine Verdunstung der austre­ tenden Flüssigkeit erfolgen kann. Das Rippenpaket 21 ist von Rundrohren 23 durchsetzt, welche beispielsweise durch mechanisches Aufweiten mit (nicht dargestellten) Durchzügen der einzelnen Faltrippen 21a wärmeleitend verbunden sind. Vorzugsweise werden die Faltrippen 21a im Bereich ihrer Öffnungen für die Rohre 23 zuvor "auf Block planiert", d. h. auf Materialstär­ ke zusammengedrückt. Dadurch werden die Stabilität und die Umformbarkeit der Rippen in diesem Bereich um die Rohre verbessert. Die Rohre 23 sind als Rohrschlange ausgebildet, und zwar mit einem Eintrittsstutzen 23a und einem Austrittsstutzen 23b, die einerseits mit dem Sammelrohr 27a eines Kondensators 27 und andererseits mit dem Kältemittelkreislauf einer nicht dargestellten Kraftfahrzeugklimaanlage verbunden sind. Somit ist die Rohr­ schlange kältemittelseitig in Reihe hinter dem Kondensator 27 geschaltet, wird also von im wesentlichen flüssigen Kältemittel durchströmt. Dem Rip­ penpaket 21 ist ein Verteilerkasten 24 stirnseitig zugeordnet, der mit einem Eintrittsstutzen 25 für Kondenswasser eines nicht dargestellten Verdampfers einer Klimaanlage versehen ist. Dieses Kondenswasser wird in dem Vertei­ lerkasten 24 gesammelt und den Kanälen der Faltungen 22 zugeführt. Der Verteilerkasten 24 ist mit einem saugfähigen Faservlies 26 ausgefüllt, wel­ ches das Kondenswasser speichert und in die Kanäle des Rippenpakets 21 weitergibt. Fig. 2, 2a, 2b show an evaporative heat exchanger 20 with egg nem fin pack 21, which is made of a Faltrippen 21 of FIG. 1 constructed. The individual folds 22 and the channels formed by them run transversely to the air flow which is indicated by the arrows A. The ribs 21 a of the fin package 21 are stacked on top of one another in such a way that an air gap 21 b is left between them, through which the ambient air flows, so that evaporation of the escaping liquid can take place in this air stream. The fin pack 21 is penetrated by round tubes 23 which are connected, for example by mechanical expansion (not shown) through the individual trains Faltrippen 21 a thermally conductive. Preferably, the folding ribs 21 a in the area of their openings for the tubes 23 are previously "leveled on a block", ie pressed together to material thickness. This improves the stability and the formability of the ribs in this area around the tubes. The tubes 23 are formed as a coil, specifically with an inlet nozzle 23 a and an outlet nozzle 23 b, which are connected on the one hand to the collecting tube 27 a of a condenser 27 and on the other hand to the refrigerant circuit of a motor vehicle air conditioning system, not shown. Thus, the pipe is connected in series on the refrigerant side behind the condenser 27 , so essentially liquid refrigerant flows through it. The Rip penpaket 21 is assigned a distribution box 24 on the end face, which is provided with an inlet connection 25 for condensed water of an evaporator of an air conditioning system, not shown. This condensed water is collected in the distribution box 24 and fed to the channels of the folds 22 . The distribution box 24 is filled with an absorbent nonwoven fabric 26 which stores the condensed water and passes it on into the channels of the fin package 21 .

Der gesamte Verdunstungs-Wärmeübertrager 20 ist mit dem Kondensator 27 verbunden, und zwar in der Weise, daß die beiden Stirnflächen 28 des Kondensators 27 und 29 des Rippenpakets 21 nebeneinander in einer ge­ meinsamen Ebene angeordnet sind und vom Umgebungsluftstrom, der durch ein nicht dargestelltes Kondensatorgebläse gefördert wird, beaufschlagt werden. Durch diese Zwangsbelüftung des Rippenpakets 21 wird die Ver­ dunstung gefördert und damit die Kühlleistung des Verdunstungs- Wärmeübertragers 20 erhöht, wodurch das in den Rohren 23 strömende Kältemittel effektiv unterkühlt wird.The entire evaporative heat exchanger 20 is connected to the condenser 27 , in such a way that the two end faces 28 of the condenser 27 and 29 of the fin package 21 are arranged side by side in a common plane and from the ambient air flow through a condenser fan, not shown is promoted, acted upon. Through this forced ventilation of the ribs 21, the packet Ver dunstung is promoted, thus increasing the cooling capacity of the evaporative heat exchanger 20, thereby flowing into the tubes 23 of refrigerant is effectively cooled.
