- the one by the DE-A 198 26 881 become known soldered flat tube evaporator is formed in two rows, ie, seen in the direction of air flow, there are two rows of flat tubes, between which corrugated fins are arranged, one behind the other, the ends of the flat tubes open into collection boxes, each through a longitudinal partition in a front and a rear chamber are divided. Within these chambers partially transverse partitions are provided.
- the flow of the refrigerant extends in the rows of flat tubes both from top to bottom and from bottom to top, wherein a deflection of the refrigerant on the one hand “in width”, ie transversely to the air flow direction and on the other hand “in depth”, ie in the air flow direction.
- Object of the present invention is therefore to improve a heat exchanger of the type mentioned in that its production is simplified and thus reduces production costs and its performance can be improved.
- the heat exchanger according to the invention is formed einreihig, d. H. the flat tubes are continuous throughout the depth (in the direction of air flow) and provided with a longitudinal divider which is brazed to the longitudinal divider wall.
- the single-row heat exchanger according to the invention and the double-row heat exchanger according to the prior art are thus functionally identical with regard to the refrigerant charge.
- From the construction according to the invention has the advantage that the continuous flat tubes and the continuous corrugated fins are much easier to cassettieren and that beyond the insertion of the flat tubes in the bottoms results in a stop that defines the insertion depth of the flat tube ends.
- the heat transfer performance is increased because a heat transfer takes place over the entire depth of the heat exchanger.
- the flat tube end is divided into two flat tube ends, which are received by passages of the soil, these passages are interrupted in the region of the longitudinal partition wall.
- the flat tube end is straight, d. H. without a recess and is absorbed by a continuous passage in the floors of the collecting tanks. This results in a good soldering of the flat tubes in the floors.
- the longitudinal dividing wall has recesses in the region of the passages and the flat tubes arranged in the passages, which are adapted to the contour of passage and flat tube and thus ensure good soldering.
- the flat tube has a constant thickness.
- the flat tube has a smaller thickness in the region of the separating web, specifically in the form of a narrow central web connecting the two flat tube halves.
- the flat tube end is also straight, ie inserted without recess and through an opening in the bottom, which corresponds to the contour of the flat tube end.
- the longitudinal dividing wall has narrow slots or recesses in the area of the narrow central webs projecting into the collecting box, which overlap the middle webs - this results in a region in which there is a dense soldering between the longitudinal dividing wall and the dividing web ensured.
- the. Openings in the ground partially as passages, ie formed in the region of the longitudinal partition broken passages.
- Fig. 1 shows as an example of a heat exchanger according to the invention a single-row flat tube evaporator 1 with a heat exchanger network 2 and an upper header 3 and a lower header 4.
- this evaporator 1 corresponds to the generic state of the art, ie DE-A 198 26 881 or DE-A-3813339 ,
- the guidance of the refrigerant, ie the flow pattern essentially corresponds to this prior art.
- Fig. 1a shows a section in the region of the collecting tube 3 from the evaporator 1.
- the collecting box 3 is divided by a longitudinal partition wall 5 into two chambers 6a and 6b, in which ends 7, 8 of flat tubes 9 open, which are formed continuously, ie the only row of tubes this Form evaporator 1. Between the flat tubes 9 continuous corrugated fins 10 are arranged, which are flowed over by ambient air.
- the collection box 4, not shown here is constructed analogously.
- Fig. 2 shows a similar section as Fig. 1a ie, an upper header 11 divided into two longitudinal chambers 12, 13.
- a continuous flat tube 14 is formed as an extruded tube and has a plurality of channels 14 'on.
- a separating web 15 is arranged, which divides the flat tube 14 into two flow paths 14a and 14b.
- the separating web 15 terminates in the upper region of the flat tube 14 which opens into the chambers 12, 13 in a recess 16 into which a longitudinal dividing wall 17 of the collecting box 11 engages.
- the flat tube 14 thus has on both sides of the recess 16 two flat tube ends 18, 19, which communicate with the flow paths 14b and 14a.

Abstract
Description
Die Erfindung bezieht sich auf einen Wärmeübertrager, insbesondere einen Verdampfer, bestehend aus einem Wärmeübertragernetz von Wellrippen und Flachrohren, nach dem Oberbegriff des Patentanspruches 1 - bekannt durch die
Der durch die
Aufgabe der vorliegenden Erfindung ist es daher, einen Wärmeübertrager der eingangs genannten Art dahingehend zu verbessern, dass seine Herstellung vereinfacht wird und damit die Produktionskosten gesenkt sowie seine Leistung verbessert werden.Object of the present invention is therefore to improve a heat exchanger of the type mentioned in that its production is simplified and thus reduces production costs and its performance can be improved.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Patentanspruches 1. Danach ist der erfindungsgemäße Wärmeübertrager einreihig ausgebildet, d. h. die Flachrohre sind über die Tiefe (in Luftströmungsrichtung) durchgehend ausgebildet und mit einem in Längsrichtung verlaufenden Trennsteg versehen, der mit der Längstrennwand verlötet ist. Der erfindungsgemäße einreihige Wärmeübertrager und der zweireihige Wärmeübertrager nach dem Stand der Technik sind somit - im Hinblick auf die Kältemittelführung - funktionell gleich. Aus der erfindungsgemäßen Bauweise ergibt sich der Vorteil, dass die durchgehenden Flachrohre und auch die durchgehenden Wellrippen wesentlich einfacher zu kassettieren sind und dass sich darüber hinaus beim Einstecken der Flachrohre in die Böden ein Anschlag ergibt, der die Einstecktiefe der Flachrohrenden definiert. Schließlich wird auch die Wärmeübertragungsleistung gesteigert, weil eine Wärmeübertragung über die gesamte Tiefe des Wärmeübertragers erfolgt.The solution of this problem arises from the features of claim 1. Thereafter, the heat exchanger according to the invention is formed einreihig, d. H. the flat tubes are continuous throughout the depth (in the direction of air flow) and provided with a longitudinal divider which is brazed to the longitudinal divider wall. The single-row heat exchanger according to the invention and the double-row heat exchanger according to the prior art are thus functionally identical with regard to the refrigerant charge. From the construction according to the invention has the advantage that the continuous flat tubes and the continuous corrugated fins are much easier to cassettieren and that beyond the insertion of the flat tubes in the bottoms results in a stop that defines the insertion depth of the flat tube ends. Finally, the heat transfer performance is increased because a heat transfer takes place over the entire depth of the heat exchanger.

Vorteilhafte Ausgestaltungen der Erfindung gemäß Anspruch 1 ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention according to claim 1 emerge from the dependent claims.
In der Erfindung weist das Ende des Flachrohres im Bereich des Trennsteges eine Aussparung auf, mit der es sich gegenüber der Unterseite des Bodens abstützt. Andererseits greift von oben die Längstrennwand in diese Aussparung ein und gewährleistet somit eine dichte Verlötung. Durch die Aussparung wird das Flachrohrende in zwei Flachrohrenden geteilt, die von Durchzügen des Bodens aufgenommen werden, wobei diese Durchzüge im Bereich der längs verlaufenden Trennwand unterbrochen sind.In the invention, the end of the flat tube in the region of the separating web on a recess with which it is supported against the underside of the bottom. On the other hand engages from above the longitudinal partition in this recess and thus ensures a tight soldering. Through the recess, the flat tube end is divided into two flat tube ends, which are received by passages of the soil, these passages are interrupted in the region of the longitudinal partition wall.
In der Erfindung ist das Flachrohrende gerade, d. h. ohne eine Aussparung und wird von einem durchgehenden Durchzug in den Böden der Sammelkästen aufgenommen. Dies ergibt eine gute Verlötung der Flachrohre in den Böden. Die Längstrennwand weist dagegen im Bereich der Durchzüge und der in den Durchzügen angeordneten Flachrohre Aussparungen auf, die an die Kontur von Durchzug und Flachrohr angepasst sind und somit eine gute Verlötung gewährleisten. Bei den zuvor erwähnten Lösungen weist das Flachrohr eine gleich bleibende Dicke auf.In the invention, the flat tube end is straight, d. H. without a recess and is absorbed by a continuous passage in the floors of the collecting tanks. This results in a good soldering of the flat tubes in the floors. In contrast, the longitudinal dividing wall has recesses in the region of the passages and the flat tubes arranged in the passages, which are adapted to the contour of passage and flat tube and thus ensure good soldering. In the aforementioned solutions, the flat tube has a constant thickness.

Das Flachrohrende ist ebenfalls gerade, d. h. ohne Aussparung und durch eine Öffnung im Boden gesteckt, die der Kontur des Flachrohrendes entspricht. Die Längstrennwand weist im Bereich der in den Sammelkasten hineinragenden schmalen Mittelstege schmale Schlitze oder Aussparungen auf, welche die Mittelstege übergreifen - dadurch ist in diesem Bereich eine dichte Verlötung zwischen Längstrennwand und Trennsteg gewährleistet. Vorteilhafterweise sind die. Öffnungen im Boden teilweise als Durchzüge, d. h. im Bereich der Längstrennwand unterbrochene Durchzüge ausgebildet.According to the invention, the flat tube has a smaller thickness in the region of the separating web, specifically in the form of a narrow central web connecting the two flat tube halves. The flat tube end is also straight, ie inserted without recess and through an opening in the bottom, which corresponds to the contour of the flat tube end. The longitudinal dividing wall has narrow slots or recesses in the area of the narrow central webs projecting into the collecting box, which overlap the middle webs - this results in a region in which there is a dense soldering between the longitudinal dividing wall and the dividing web ensured. Advantageously, the. Openings in the ground partially as passages, ie formed in the region of the longitudinal partition broken passages.
