PATENTANSPRUCH Verdampfer für den Einbau in Klimageräten, insbesondere solchen für Kraftfahrzeuge, mit wenigstens einer Leitung für das Kühlfluid und einem Paket von an der Leitung befestigten Lamellen, dadurch gekennzeichnet, dass das Lamellenpaket des Verdampfers mit zusätzlichen Leitungen (5) für ein Heiz-fluid versehen ist. PATENT CLAIM Evaporator for installation in air conditioning devices, in particular those for motor vehicles, with at least one line for the cooling fluid and a set of fins attached to the line, characterized in that the fin set of the evaporator is provided with additional lines (5) for a heating fluid is. Die Erfindung bezieht sich auf einen Verdampfer für den Einbau in Klimageräten, insbesondere solchen für Kraftfahrzeuge, z.B. Omnibusse, mit wenigstens einer Leitung für das Kühlfluid und einem Paket von an der Leitung befestigten Lamellen.The invention relates to an evaporator for installation in air conditioning units, in particular those for motor vehicles, e.g. omnibuses, with at least one line for the cooling fluid and a set of fins attached to the line. Aus der Praxis sind bislang lediglich Verdampfer bekannt, die mit Leitungen für das Kühlfluid ausgestattet sind. Um mit Klimageräten sowohl erhitzen als auch abkühlen zu können, benutzt man neben den Verdampfern ein eigenes Heizaggregat, das bei Kraftfahrzeugen vornehmlich aus einem Wärmetauscher besteht. Die beiden Aggregate, nämlich der Verdampfer und das Heizaggregat benötigen relativ viel Raum, weshalb das Klimagerät entsprechend dimensioniert sein muss.Only evaporators that are equipped with lines for the cooling fluid are known from practice. In order to be able to both heat and cool with air conditioners, a separate heating unit is used in addition to the evaporators, which in motor vehicles mainly consists of a heat exchanger. The two units, namely the evaporator and the heating unit, require a relatively large amount of space, which is why the air conditioning unit must be dimensioned accordingly. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen günstig herzustellenden Verdampfer der eingangs genannten Art zu schaffen, der relativ klein gebaut ist und trotzdem die Möglichkeit bietet, die Lufttemperatur in grossen Bereichen zu regeln.The present invention is based on the object of creating an evaporator of the type mentioned at the outset that is inexpensive to produce and that is relatively small and nevertheless offers the possibility of regulating the air temperature over a wide range. Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Lamellenpaket des Verdampfers mit zusätzlichen Leitungen für ein Heizfluid versehen ist.According to the invention, this object is achieved in that the lamella pack of the evaporator is provided with additional lines for a heating fluid. Die beim erfindungsgemässen Verdampfer vorgesehene zusätzliche Leitung für das Heizfluid bietet die Möglichkeit, das gesamte Lamellenpaket des Verdampfers auch für das Aufheizen der Luft zu verwenden. Dasselbe gilt im umgekehrten Fall bei Kühlung. Ein spezielles Heizaggregat kann daher entfallen. Der erfindungsgemässe Verdampfer stellt ein kompaktes Gerät dar, das zur Temperaturregelung der Luft über den vollen Arbeitsbereich verwendet werden kann.The additional line provided for the heating fluid in the evaporator according to the invention offers the possibility of also using the entire lamellar assembly of the evaporator for heating the air. The same applies in the opposite case with cooling. A special heating unit can therefore be omitted. The evaporator according to the invention represents a compact device which can be used to control the temperature of the air over the full working range. Im folgenden ist ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung beschrieben. Es zeigen:In the following an embodiment of the invention is described with reference to a drawing. Show it: Fig. 1 eine Draufsicht auf den Verdampfer und Fig. 2 einen Schnitt durch den in Fig. 1 gezeigten Ver-5 dampfer längs der Linie II-II.1 shows a top view of the evaporator and FIG. 2 shows a section through the evaporator shown in FIG. 1 along the line II-II. In der Zeichnung ist der Verdampfer insgesamt mit dem Bezugszeichen 1 versehen. Er ist für den Einbau in Klimageräte von Kraftfahrzeugen, insbesondere Omnibussen gedacht, er kann jedoch auch in anderen Klimageräten Verwendung io finden.In the drawing, the evaporator is provided with the reference number 1 as a whole. It is intended for installation in air conditioning units in motor vehicles, in particular buses, but it can also be used in other air conditioning units. Der Verdampfer ist mit ersten Leitungen 2 ausgestattet, die für das durch den Verdampfer durchzuleitende Kühlfluid vorgesehen sind. Diese Leitungen sind in hin- und zurückführende Stränge aufgeteilt, die an dem einen Ende mit Bögen 3 und 15 im Bereich des anderen Endes mit einem Sammelrohr 4 miteinander in Verbindung stehen.The evaporator is equipped with first lines 2 intended for the cooling fluid to be passed through the evaporator. These lines are divided into lines leading back and forth, which are connected to one another at one end with bends 3 and 15 in the region of the other end with a collecting pipe 4 . Weiterhin weist der Verdampfer auf der Luftaustrittsseite eine zweite Leitung 5 auf, die für den Durchfluss des Heiz-fluids bestimmt ist. Diese Leitung ist innerhalb des Verdamp-20 fers nicht verzweigt, sie besitzt jedoch einen hin- und zurückführenden Strang, der ebenfalls über ein Bogenstück 6 miteinander verbunden ist. In Fig. 1 sind auf der rechten Seite die jeweiligen Anschlüsse für die ersten und zweiten Leitungen gezeigt. An den Leitungen sind, im wesentlichen parallel zu-25 einander, die Lamellen 7 befestigt.Furthermore, the evaporator has a second line 5 on the air outlet side, which is intended for the flow of the heating fluid. This line is not branched within the evaporator 20 fers, however, it has a reciprocating line that is also connected to one another via a bend piece 6 . The respective connections for the first and second lines are shown on the right-hand side in FIG. The slats 7 are fastened to the lines essentially parallel to one another. In Fig. 2 ist gezeigt, dass unterhalb der Lamellen des Verdampfers eine Tropfschale 8 angeordnet ist. Die Tropfschale bildet einen Teil des in Fig. 2 angedeuteten Gehäuses 9 des Verdampfers.FIG. 2 shows that a drip tray 8 is arranged below the fins of the evaporator. The drip tray forms part of the housing 9 of the evaporator indicated in FIG. 30 Der Verdampfer arbeitet wie folgt:30 The evaporator works as follows: Für das Abkühlen der durch den Verdampfer durchzufördernden Luft wird dieser über die Leitungen 2 mit einem Kühlfluid beaufschlagt. Das Kühlfluid verdampft innerhalb dieser Leitungen und führt deshalb eine Abkühlung der Lei-35 tungen und der Lamellen herbei. Die durchstreifende Luft kühlt sich dabei ab. Soweit diese Luft erhitzt werden soll, wird derZufluss des Kühlfluids gestoppt. Statt dessen wird der Verdampfer über die Leitung 5 mit einem Heizfluid, z.B. dem Kühlwasser des Kraftfahrzeugs beaufschlagt. Das Heizfluid 40 gibt seine Wärme an das Rohr 5 und an die Lamellen 7 ab. Die durchströmende Luft erwärmt sich.To cool the air to be conveyed through the evaporator, a cooling fluid is applied to it via the lines 2 . The cooling fluid evaporates within these lines and therefore causes the lines and the fins to cool down. The air passing through cools down. To the extent that this air is to be heated, the flow of cooling fluid is stopped. Instead, the evaporator is supplied with a heating fluid, e.g. the cooling water of the motor vehicle, via the line 5 . The heating fluid 40 gives off its heat to the pipe 5 and to the fins 7 . The air flowing through heats up. vv 1 Blatt Zeichnungen1 sheet of drawings
