Definitions
- the invention relates to a heat exchanger for heating a motor vehicle according to the preamble of claim 1.
- Heat exchangers for heating motor vehicles are nowadays usually designed as soldered all-metal heat exchangers.
- Known radiators have a radiator block, also called a short block, which is composed of tubes and ribs, preferably flat tubes and corrugated fins.
- the pipes open into collection boxes and are soldered to the floors of the collection boxes.
- the ribs of the block are overflowed by ambient air, which absorbs the heat of the coolant and transported into the passenger compartment.
- An important criterion for a radiator is a uniform air outlet temperature distribution, if possible over the entire air outlet level, d. H. in height and in width direction.
- the heat exchanger in short the radiator, is designed in disk construction, ie the flow channels are formed by a package of disks, one disk in each case has two interconnected disc halves, which are flowed through the heat transfer fluid, preferably a coolant Moflutig.
- the disc design is known per se, especially in oil coolers for motor vehicles. Two disc halves each have an erect provided with a fold edge, which is integrally connected to the fold of the other disc, in particular by soldering.
- the advantage of the disc construction is, inter alia, that the individual discs can be relatively easily added to a package and have geometrically simple, mostly flat solder surfaces, which can be soldered securely pressure and liquid-tight.
- the manufacturing process of the disk-type radiator according to the invention is therefore easy to control, in particular no leaks are to be expected.
- the discs have in their interior partitions to form flow channels, deflecting zones are arranged in a further advantageous embodiment at the end of the dividing walls, so that adjacent flow channels are interconnected within a disc and the heat transfer fluid, in particular the coolant can be deflected in the depth direction ,
- the discs have inlet and outlet openings which are cup-shaped and connected in a fluid-tight manner to the corresponding inlet and outlet openings of adjacent discs.
- the inlet and outlet openings of a plurality of juxtaposed slices together form collecting channels which connect the slices to one another, ie the slices communicate on the coolant side via the collecting channels, both on the inlet and on the outlet side.
- the collecting channels are thus comparable to the chambers of a collecting box, which is divided by a longitudinal partition wall.
- the individual panes can be easily and safely soldered to each other via the cup-shaped openings, which each have peripheral folds.
- the collecting ducts may be arranged on one side of the disk pack or on both sides, depending on where the inlet and / or outlet of the coolant is to be placed.
- two adjacent collection channels are connected to each other by an outer deflection channel.
- the deflection channel Through the deflection channel, the heat carrier fluid is led out of the disk package, mixed, introduced into the adjacent collection channel and distributed from there into the parallel flow channels of the individual disks. Through this outer deflection, a homogenization of the air outlet temperature is achieved.
- the flow cross section of the deflection channel is smaller than the sum of the flow cross sections of the flow channels in the discs.
- the flow cross section of the deflection channel is preferably from 20 to 40% of the sum of the individual flow cross sections.
- the radiator according to the invention is flowed through four-flow, wherein the first and third deflection of the heat transfer fluid takes place within the discs and in the deflection zones, while the second deflection takes place outside of the discs via the deflection channel.
- the coolant temperature profile which is still asymmetrical after the first two flow passages is made uniform by the deflection of the coolant in the deflection channel, so that a homogeneous air outlet temperature profile results after the third and fourth passage of the coolant at the air outlet side.
- the deflection channel is arranged within a first side part, preferably formed in the side part, which closes the disc package on one side to the outside.
- a second side part which has an inlet and outlet opening and forms the conclusion of the second side of the disk package to the outside.
- the radiator according to the invention only three different items, d. H. three different types of discs.
- the first type of disc has inlet and outlet openings, dividing walls and deflection zones.
- the second disc type is formed as a first side part and has the deflection channel.
- the third disc type is formed as a second side part and has an inlet and outlet opening.
- secondary surfaces in particular corrugated fins are arranged between the discs, which increase the heat exchange surface on the air side, d. H. serve an improvement of the air side heat transfer.
- Fig. 1 shows a radiator 1 according to the invention in disc design, ie the radiator 1 is constructed from a plurality of discs 2, which form flow channels for a heat transfer fluid, preferably for a coolant of a cooling circuit of an internal combustion engine of a motor vehicle.
- the discs 2 have in their upper region cup-shaped openings 3, 4, 5, 6, which together with the adjacent cup-shaped openings, also called short wells 3, 4, 5, 6, collecting channels 7, 8, 9, 10 form.
- the term "collection channel” which is used exclusively here also encompasses the term “distribution channel”.
- the disks 2 do not have continuous partitions 11, 12 and a continuous partition wall 13 in the middle. All disks 2 are made of an aluminum material and soldered together, as will be explained in more detail later.
- the flow path of the coolant is shown schematically by flow arrows K1 to K9.
- the non-continuous partitions 11, 12 form deflection zones 14, 15, via which the coolant can be deflected in the depth direction.
- the radiator 1 is traversed between the discs 2 of air, which is indicated by the two arrows L1, L2.
- L1, L2 To improve the heat transfer 2 secondary surfaces, not shown, are arranged in the form of corrugated fins between the discs, which are soldered to the discs.
- the heated air is - which is not shown - fed to the passenger compartment of a motor vehicle.
- the coolant enters according to the arrow K1 in the collecting channel 7 of the radiator 1 and is distributed to the interiors of the individual panes 2 and flows in these according to the arrow K2 down.
- the coolant is deflected in accordance with the arrow K3 in depth, ie opposite to the air flow direction L1, L2 and flows according to the arrow K4 upwards.
- the arrows K2, K3, K4 apply to each individual slice 2 of the entire disc pack.
- the coolant then collects in the collecting channel 8, from where it is led out according to the arrow K5 from the package of disks 2 via a channel, not shown here, and guided into the adjacent collecting channel 9.
- Fig. 2 shows the radiator 1 in a perspective overall view with a first side part 16, in which a deflection channel 17 is formed.
- the deflection channel 17 is above the two in Fig. 2 invisible cup openings 4, 5 with the collecting channels 8, 9 (see. Fig. 1 ) and thus causes the deflection of the coolant according to the arrow K5 in Fig. 1 , While the coolant according to the arrows K3, K7 is deflected within each of the individual disks 2, the deflection takes place according to the arrow K5 via the deflection channel 17 outside of the disks.
- the flow cross section in the deflection channel 17 is preferably smaller than the sum of the flow channel cross sections of the individual disks 2, so that the coolant flow in the region of the deflection channel 17 undergoes a so-called throttling due to cross-sectional constriction. Due to the cross-sectional constriction creates a certain congestion effect, with the result that the emerging from the collecting channel 8 coolant is well mixed, ie receives a homogenized coolant temperature.
- the flow cross section of the deflection channel 17 is preferably 20 to 40% of the sum of the flow channel cross sections in the individual disks 2. This measure of the "outer deflection" results in a largely homogeneous air temperature exit profile, ie on the side of the exiting air arrows L1, L2 (see. Fig. 1 ).
- Fig. 3 shows the heating element 1 in a sectional view with flow arrows for the coolant and the air.
- the entering coolant is indicated by an arrow K E and the escaping coolant by an arrow K A , while the entering into the radiator 1 air is marked L E.
- the in the individual disks 2 perpendicular to the plane extending flow channels, corresponding to the arrows K2, K4, K6, K8 in Fig. 1 are in Fig. 3 marked as rows R1, R2, R3, R4.
- the coolant flow thus runs in the row R1 according to the two arrow symbols (cross) down, in the row R2 corresponding to the arrow symbols (Point) up, in row R3 down and in row R4 back up.
- each disc 2 consists of two disc halves 2a, 2b, each having a cup 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b.
- Fig. 4 shows the radiator 1 in a plan view, wherein the discs 2, each consisting of the disc halves 2a, 2b, the first side member 16 with deflecting channel 17 and a second side member 18 are visible - they together form the disc package
- Fig. 5 shows the second side part 18, which has an inlet opening 18a and an outlet opening 18b, which are arranged coaxially to the collecting channels 7 and 10.
- the second disc part 18 thus acts as a connection part for the supply and discharge of the coolant.
- Fig. 6 shows a single disc half 2a, with the two non-continuous partitions 11a, 12a and the continuous partition wall 13a.
- the cups 3a, 4a, 5a, 6a are additionally arranged with arrow symbols for incoming and outgoing flow.
- b4 could be twice that of b1.
- the height of the deflection zones 14a, 15a is designated h1, where h1 ⁇ b1.
- the height of the disk 2a is designated by h, where h According to a preferred embodiment in the range of 100 to 400 mm, while the construction or network depth T is in a range of 10 to 120 mm, preferably from 25 to 80 mm.
- Fig. 7 shows a disc half 2a in a perspective "transparent" representation.
- the non-continuous partition walls 11a, 12a and the continuous partition wall 13a are raised in the form of embossed beads.
- Fig. 8 shows a disc 2, made up of two disc halves 2a, 2b, in perspective "transparent" representation. Both disc halves 2a, 2b are soldered together over the entire circumference, via the partitions 11a, 12a, 13a tightly together.
- Fig. 9 shows a half disc 2a in section, wherein the formed as trapezoidal beads partitions 11a, 12a, 13a are visible.
- Fig. 10 shows the disc 2, consisting of the disc halves 2a, 2b, in section.
- the disc 2 has a circumferential, soldered fold 19 and is thus sealed to the outside.
- the partitions 11, 12, 13 are formed to form the flow channels.
- Fig. 10a shows a detail E from Fig. 10 in an enlarged view, in which a channel width B1 (clear width), a cup height B3 and a material thickness s are shown.
- the channel width B1 is preferably selected in a range of 0.5 to 2.5 mm, and the cup height B3 ranges in the range of 1.5 to 5.0 mm. This measure corresponds to half the width of a corrugated fin, which is arranged between the discs 2.
- the material thickness s ranges from 0.15 to 0.5 mm for an aluminum material.
- Fig. 11 shows a section through the disc 2 in the region of the wells 3, 4, 5, 6, which determine the maximum height of the disc 2, marked B4.
- B4 is preferably in the range of 3.8 to 13.5 mm.
- the entire radiator 1 can be made according to the illustrated and described embodiment of only three different items: these are the disc 2, consisting of two disc halves 2a, 2b, the first side member 16 with deflection 17 and the second side member 18 with inlet and outlet openings 18a, 18b.
- the small number of individual parts lowers the manufacturing costs.
- the soldering process is easy to control because all the surfaces to be soldered are even (circumferential fold, partitions, cups), so that an error-free Dichtlötung is guaranteed. With this design, a radiator with multiple deflection can thus be produced process reliable.
- turbulence sheets can be arranged in the disks 2, which are also soldered to the disks.

Description
Die Erfindung betrifft einen Wärmeübertrager zur Beheizung eines Kraftfahrzeuges nach dem Oberbegriff des Patentanspruches 1.The invention relates to a heat exchanger for heating a motor vehicle according to the preamble of
Wärmeübertrager zur Beheizung von Kraftfahrzeugen, auch kurz Heizkörper genannt, sind heutzutage in der Regel als gelötete Ganzmetallwärmeübertrager ausgebildet. Bekannte Heizkörper weisen einen Heizkörperblock, auch kurz Block genannt, auf, welcher aus Rohren und Rippen, vorzugsweise Flachrohren und Wellrippen aufgebaut ist. Die Rohre münden in Sammelkästen und sind mit den Böden der Sammelkästen verlötet. Durch die Rohre der Heizkörper strömt erwärmtes Kühlmittel, welches dem Kreiskühlkreislauf der Brennkraftmaschine entnommen wird. Die Rippen des Blockes werden von Umgebungsluft überströmt, welche die Wärme des Kühlmittels aufnimmt und in den Fahrgastraum transportiert. Ein wichtiges Kriterium für einen Heizkörper ist eine gleichmäßige Luftaustrittstemperaturverteilung, möglichst über die gesamte Luftaustrittsebene, d. h. in Höhen- und in Breitenrichtung.Heat exchangers for heating motor vehicles, also called radiators for short, are nowadays usually designed as soldered all-metal heat exchangers. Known radiators have a radiator block, also called a short block, which is composed of tubes and ribs, preferably flat tubes and corrugated fins. The pipes open into collection boxes and are soldered to the floors of the collection boxes. Through the tubes of the radiator heated coolant flows, which is removed from the circuit cooling circuit of the internal combustion engine. The ribs of the block are overflowed by ambient air, which absorbs the heat of the coolant and transported into the passenger compartment. An important criterion for a radiator is a uniform air outlet temperature distribution, if possible over the entire air outlet level, d. H. in height and in width direction.
In der
Es ist auch bekannt, wie z. B. in der
Die Übertragung dieses Prinzips der Mehrfachumlenkung im Kreuzgegenstrom auf moderne Heizkörper, wie er z. B. in der vorgenannten Druckschrift der Anmelderin beschrieben ist, bereitet Probleme, insbesondere wenn man in einem Sammelkasten zwei oder mehr Längstrennwände hintereinander anordnen und dicht mit den Rohren, Rohrböden und der Wandung des Sammelkastens verlöten soll. Es ist vielmehr damit zu rechnen, dass die durch die Längstrennwände abzuteilenden Kammern nicht vollständig gegeneinander abgedichtet sind und dass eine Leckage auftritt. Dies vermindert, insbesondere bei kleinen Volumenströmen des Kühlmittels die Leistung des Heizkörpers.The transfer of this principle of multiple deflection in the countercurrent flow on modern radiators, as he z. As described in the aforementioned document of the Applicant, is causing problems, especially if you arrange in a collection box two or more longitudinal partitions in a row and to solder tightly to the pipes, tube sheets and the wall of the header tank. Rather, it is to be expected that the chambers to be partitioned off by the longitudinal dividing walls are not completely sealed off from each other and that leakage occurs. This reduces, especially at low flow rates of the coolant, the performance of the radiator.
Es ist Aufgabe der Erfindung, einen Wärmeübertrager der eingangs genannten Art dazustellen, der fertigungstechnisch beherrschbar und mit relativ geringem Kostenaufwand herstellbar ist. Es ist ferner Aufgabe der Erfindung, dass der aus dem Heizkörper austretende Luftstrom ein möglichst homogenes Luftaustrittstemperaturprofil aufweist, auch bei geringen Volumenströmen des Wärmeträgerfluids.It is an object of the invention to provide a heat exchanger of the type mentioned, which is manageable and manufacturable at relatively low cost. It is a further object of the invention that the air flow emerging from the radiator has the most homogeneous possible air outlet temperature profile, even at low volume flows of the heat transfer fluid.
Die Aufgabe der Erfindung wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object of the invention is solved by the features of
Erfindungsgemäß ist vorgesehen, dass der Wärmeübertrager, kurz gesagt der Heizkörper, in Scheibenbauweise ausgebildet ist, d. h. die Strömungskanäle werden durch ein Paket von Scheiben gebildet, wobei eine Scheibe jeweils zwei miteinander verbundene Scheibenhälften aufweist, die mehrflutig vom Wärmeträgerfluid, vorzugsweise einem Kühlmittel durchströmbar sind. Die Scheibenbauweise ist an sich bekannt, insbesondere bei Ölkühlern für Kraftfahrzeuge. Zwei Scheibenhälften weisen jeweils einen aufgestellten mit einem Falz versehenen Rand auf, welcher mit dem Falz der anderen Scheibe stoffschlüssig, insbesondere durch Löten verbunden wird. Der Vorteil der Scheibenbauweise besteht unter anderem darin, dass die einzelnen Scheiben relativ leicht zu einem Paket gefügt werden können und geometrisch einfache, meistens ebene Lötflächen aufweisen, die sich sicher druck- und flüssigkeitsdicht verlöten lassen. Der Herstellungsprozess des erfindungsgemäßen Heizkörpers in Scheibenbauweise ist daher gut beherrschbar, insbesondere sind keine Leckagen zu erwarten.According to the invention, it is provided that the heat exchanger, in short the radiator, is designed in disk construction, ie the flow channels are formed by a package of disks, one disk in each case has two interconnected disc halves, which are flowed through the heat transfer fluid, preferably a coolant mehrflutig. The disc design is known per se, especially in oil coolers for motor vehicles. Two disc halves each have an erect provided with a fold edge, which is integrally connected to the fold of the other disc, in particular by soldering. The advantage of the disc construction is, inter alia, that the individual discs can be relatively easily added to a package and have geometrically simple, mostly flat solder surfaces, which can be soldered securely pressure and liquid-tight. The manufacturing process of the disk-type radiator according to the invention is therefore easy to control, in particular no leaks are to be expected.
In vorteilhafter Ausgestaltung weisen die Scheiben in ihrem Inneren Trennwände zur Bildung von Strömungskanälen auf, wobei in weiterer vorteilhafter Ausgestaltung am Ende der Trennwände Umlenkzonen angeordnet sind, sodass benachbarte Strömungskanäle innerhalb einer Scheibe miteinander verbunden sind und das Wärmeträgerfluid, insbesondere das Kühlmittel in Tiefenrichtung umgelenkt werden kann.In an advantageous embodiment, the discs have in their interior partitions to form flow channels, deflecting zones are arranged in a further advantageous embodiment at the end of the dividing walls, so that adjacent flow channels are interconnected within a disc and the heat transfer fluid, in particular the coolant can be deflected in the depth direction ,
In weiterer vorteilhafter Ausgestaltung weisen die Scheiben Ein- und Austrittsöffnungen auf, welche napfartig ausgebildet und fluiddicht mit den korrespondierenden Ein- und Austrittsöffnungen benachbarter Scheiben verbunden sind. Die Ein- und Austrittsöffnungen mehrerer nebeneinander angeordneter Scheiben bilden zusammen Sammelkanäle, welche die Scheiben miteinander verbinden, d. h. die Scheiben kommunizieren kühlmittelseitig über die Sammelkanäle, sowohl auf der Eintritts- als auch auf der Austrittsseite. Die Sammelkanäle sind somit vergleichbar mit den Kammern eines Sammelkastens, welcher durch eine Längstrennwand unterteilt ist. Allerdings ergibt sich für die erfindungsgemäße Bauweise der Vorteil, dass die einzelnen Scheiben über die napfartigen Öffnungen, welche jeweils umlaufende Falze aufweisen, leicht und sicher miteinander verlötbar sind.In a further advantageous embodiment, the discs have inlet and outlet openings which are cup-shaped and connected in a fluid-tight manner to the corresponding inlet and outlet openings of adjacent discs. The inlet and outlet openings of a plurality of juxtaposed slices together form collecting channels which connect the slices to one another, ie the slices communicate on the coolant side via the collecting channels, both on the inlet and on the outlet side. The collecting channels are thus comparable to the chambers of a collecting box, which is divided by a longitudinal partition wall. However, there is the advantage for the construction according to the invention that the individual panes can be easily and safely soldered to each other via the cup-shaped openings, which each have peripheral folds.
Die Sammelkanäle können auf einer Seite des Scheibenpaketes oder auf beiden Seiten angeordnet sein, je nach dem, wo der Ein- und/oder Austritt des Kühlmittels platziert sein soll.The collecting ducts may be arranged on one side of the disk pack or on both sides, depending on where the inlet and / or outlet of the coolant is to be placed.
Nach einer besonders vorteilhaften Weiterbildung der Erfindung sind zwei benachbarte Sammelkanäle durch einen äußeren Umlenkkanal miteinander verbunden. Durch den Umlenkkanal wird das Wärmeträgerfluid aus dem Scheibenpaket herausgeführt, durchmischt, in den benachbarten Sammelkanal eingeführt und von dort in die parallel geschalteten Strömungskanäle der einzelnen Scheiben verteilt. Durch diese äußere Umlenkung wird eine Homogenisierung der Luftaustrittstemperatur erreicht.According to a particularly advantageous embodiment of the invention, two adjacent collection channels are connected to each other by an outer deflection channel. Through the deflection channel, the heat carrier fluid is led out of the disk package, mixed, introduced into the adjacent collection channel and distributed from there into the parallel flow channels of the individual disks. Through this outer deflection, a homogenization of the air outlet temperature is achieved.
Nach einer weiteren vorteilhaften Ausgestaltung ist der Strömungsquerschnitt des Umlenkkanals kleiner als die Summe der Strömungsquerschnitte der Strömungskanäle in den Scheiben. Vorzugsweise beträgt der Strömungsquerschnitt des Umlenkkanals 20 bis 40 % der Summe der Einzelströmungsquerschnitte. Dadurch wird eine so genannte Androsselung des Kühlmittelstromes erreicht, d. h. durch die Querschnittsverengung im Unlenkkanal ergibt sich ein gewisser Staueffekt, wodurch die Durchmischung des Kühlmittels, d. h. eine Vergleichmäßigung der Kühlmitteltemperatur begünstigt wird.According to a further advantageous embodiment, the flow cross section of the deflection channel is smaller than the sum of the flow cross sections of the flow channels in the discs. The flow cross section of the deflection channel is preferably from 20 to 40% of the sum of the individual flow cross sections. As a result, a so-called throttling of the coolant flow is achieved, d. H. Due to the cross-sectional constriction in the Unlenkkanal results in a certain congestion effect, whereby the mixing of the coolant, d. H. a homogenization of the coolant temperature is favored.
Nach einer besonders bevorzugten Ausführungsform wird der erfindungsgemäße Heizkörper vierflutig durchströmt, wobei die erste und dritte Umlenkung des Wärmeträgerfluids innerhalb der Scheiben und in den Umlenkzonen erfolgt, während die zweite Umlenkung außerhalb der Scheiben über den Umlenkkanal erfolgt. Das nach den ersten beiden Strömungsdurchgängen noch unsymmetrische Kühlmitteltemperaturprofil wird durch die Umlenkung des Kühlmittels im Unlenkkanal vergleichmäßigt, sodass sich nach dem dritten und vierten Durchgang des Kühlmittels an der Luftaustrittsseite ein homogenes Luftaustrittstemperaturprofil ergibt.According to a particularly preferred embodiment, the radiator according to the invention is flowed through four-flow, wherein the first and third deflection of the heat transfer fluid takes place within the discs and in the deflection zones, while the second deflection takes place outside of the discs via the deflection channel. The coolant temperature profile which is still asymmetrical after the first two flow passages is made uniform by the deflection of the coolant in the deflection channel, so that a homogeneous air outlet temperature profile results after the third and fourth passage of the coolant at the air outlet side.
Nach einer vorteilhaften Weiterbildung ist der Umlenkkanal innerhalb eines ersten Seitenteiles angeordnet, vorzugsweise in das Seitenteil eingeformt, welches das Scheibenpaket auf einer Seite nach außen abschließt.According to an advantageous development of the deflection channel is arranged within a first side part, preferably formed in the side part, which closes the disc package on one side to the outside.
Nach einer weiteren vorteilhaften Ausgestaltung ist ein zweites Seitenteil vorgesehen, welches eine Ein- und Austrittsöffnung aufweist und den Abschluss der zweiten Seite des Scheibenpaketes nach außen bildet.According to a further advantageous embodiment, a second side part is provided, which has an inlet and outlet opening and forms the conclusion of the second side of the disk package to the outside.
Nach einer bevorzugten Ausführungsform weist der erfindungsgemäße Heizkörper nur drei unterschiedliche Einzelteile auf, d. h. drei unterschiedliche Scheibentypen. Der erste Scheibentyp weist Ein- und Austrittsöffnungen, Trennwände und Umlenkzonen auf. Der zweite Scheibentyp ist als erstes Seitenteil ausgebildet und weist den Umlenkkanal auf. Der dritte Scheibentyp ist als zweites Seitenteil ausgebildet und weist eine Ein- und Austrittsöffnung auf.According to a preferred embodiment, the radiator according to the invention only three different items, d. H. three different types of discs. The first type of disc has inlet and outlet openings, dividing walls and deflection zones. The second disc type is formed as a first side part and has the deflection channel. The third disc type is formed as a second side part and has an inlet and outlet opening.
In weiterer vorteilhafter Ausgestaltung sind zwischen den Scheiben Sekundärflächen, insbesondere Wellrippen angeordnet, welche der Vergrößerung der Wärmeaustauschfläche auf der Luftseite, d. h. einer Verbesserung des luftseitigen Wärmeüberganges dienen.In a further advantageous embodiment, secondary surfaces, in particular corrugated fins are arranged between the discs, which increase the heat exchange surface on the air side, d. H. serve an improvement of the air side heat transfer.
