Definitions
- the invention relates to a heat exchanger for at least one heat transport medium, as used for example as a radiator for heating in the vehicle interior of a motor vehicle incoming air.
- the invention further relates to a coolant circuit and an air treatment device for motor vehicles using such a heat exchanger.
- Heat exchangers are used, inter alia, in motor vehicles for different tasks.
- heat exchangers for engine cooling in a broader sense z. B. used as a coolant radiator, oil cooler, exhaust gas cooler and intercooler.
- Another common application of heat exchangers in motor vehicles is the temperature of the air supplied into the passenger compartment.
- heat exchangers z. B. in the form of evaporators, condensers (or gas coolers), internal heat exchangers and radiators used.
- heat exchangers now exist in a wide variety of designs and types of installation. If at least one at least partially liquid heat transport medium is used in heat exchangers, as it is z. As is the case with coolant radiators or radiators, if necessary, the problem of air accumulation in the heat exchanger, which may possibly adversely affect the throughput or the uniform distribution of the heat transfer medium in the heat exchanger. This is especially true for standing installed heat exchangers.
- One possibility is to set up the heat exchanger, for example by means of a flat installation position or a corresponding arrangement of flow or return openings, in such a way that air accumulating in the heat exchanger can escape from the heat exchanger or can be removed, for example. when the system is not even accumulated.
- a problem with such established heat exchangers is that certain installation methods (such as, for example, vertical installation of the heat exchanger) or specific designs of the supply openings for the heat transport medium are in fact excluded.
- this is often problematic especially in motor vehicles, since the space in the front part of the motor vehicle is usually very tight and certain configurations of the heat exchanger due to the other engine compartment modules are partially unavoidable.
- Another possible solution is to allow a certain amount of air accumulation in the heat exchanger and to rely on the fact that at a certain throughput of heat transfer medium, the gas collections are entrained in the heat exchanger from the heat transfer medium through the heat exchanger.
- the problem here is that in particular at low throughputs of heat transport medium the Efficiency of the heat exchanger can be reduced by the accumulation of air from both the absolute performance as well as the uniformity of heat dissipation. In particular, the latter can lead to thermal stresses and be disadvantageous due to the uneven heat distribution on the radiator surface, especially in the treatment of air for the passenger compartment.
- Another problem is that the radiators tend to cause noise due to the accumulation of gas, which is disadvantageous in particular with components arranged in the vehicle interior (such as, for example, in the case of the radiator of an air conditioning system).
- the DE 100 41 121 A1 discloses a heat exchanger having a flow and a return and at least one venting device, wherein the venting device is arranged at a distance from at least one return opening in the heat exchanger.

It has surprisingly been shown that such an arrangement of the ventilation device can ensure a particularly advantageous ventilation of the heat exchanger. Up to now it has been assumed that an arrangement of the venting devices in the immediate vicinity of the return line is advantageous since it allows the gas accumulations to be sucked off particularly effectively.
- the ventilation device it is preferable to also form the ventilation device at a distance from at least one feed opening in the heat exchanger.
- a kind of additional "vent circuit" are created especially in the upper part of the radiator, which in particular passes through the critical areas of the heat exchanger and thereby vent the heat exchanger particularly effective. It is of course important to ensure that the throughput of this additional vent circuit selected relatively low so that the efficiency of the heat exchanger does not decrease significantly.
- the distance between at least one ventilation device and at least one flow opening and / or between at least one ventilation device and at least one return opening is at least 10 mm, preferably at least 15 mm, particularly preferably at least 20 mm and in particular at least 25 mm.
- the proposed values have proved favorable.
- other numerical values are conceivable. In particular, even with other numerical data occurring in this document, at (half) intervals and discrete values, all numerical values are to be regarded as disclosed and applicable in any desired manner.
- At least one flow opening and at least one return opening are arranged adjacent to one another. This can ensure a compact construction and a simple assembly, but also a particularly effective ventilation.
- At least one venting device is arranged at a distance from the direct connecting path between at least one feed opening and at least one return opening.
- the venting device is arranged as far as possible from the direct connection path between the feed opening and the return opening.
- the invention can be used particularly advantageously in connection with vertically arranged heat exchangers with advantageously at least one, preferably overhead, coolant box. Particularly in such heat exchangers, gas accumulations are easily generated, which can be eliminated particularly effectively using the present invention.

- the openings are made as an expression, which is advantageously formed in a coolant box, preferably in an overhead coolant box of the heat exchanger.
- the openings are particularly preferably provided in a contact region between the partition wall and the coolant box wall, in particular in an overhead region of the coolant box.
- the opening may be located in the region of an optionally existing connecting seam of the coolant box.
- At least one ventilation device has at least one flow-limiting device, which is designed in particular as a baffle plate, as a tube, as a molded-on flange and / or as a hydrodynamic flow-limiting device.
- the proposed radiator should, at least in areas where it can lead to gas accumulation, as possible no sharp edges and other construction geometries, which can lead to unwanted noise.
- the noise can be further reduced by the currents occurring in particular from the speed and / or throughput can be reduced.
- the term "hydrodynamic flow restricting device” is to be understood quite generally as meaning devices in which a hydrodynamic dynamic pressure of the heat transport medium flowing through the heat exchanger is used to limit other flow paths, in particular of the material flowing through the venting devices.
- At least one ventilation device as an external ventilation device outside the heat exchanger body and / or the coolant reservoir.
- the venting device can for example be arranged as far away from the passenger compartment or in areas where only a few noises occur or the resulting noise is transmitted to a reduced extent in the motor vehicle interior.
- This flange region can be provided for example with a certain distance from the heat exchanger in the flow or return line.
- this distance between flange and radiator - and thus the distance of the venting device to the radiator - is usually relatively small, and is usually 10-50 mm, e.g. 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm or 50 mm.

- the values 5, 6, 7, 8, 9 and 10 have proven to be particularly useful.
- the n-comers can not be just regular (isosceles) n-comers, but arbitrary, general n-comers.
- the recess is formed as a concave, lenticular formation 22, which may be particularly preferably formed in the radius region of the partition wall.
- the radius of the lens preferably corresponds essentially the radius of the partition.
- other radii - in extreme cases also a straight line - are conceivable in this context.
- FIGS. 4I and 4J shown that only part of the lens after FIG. 4H is removed from the partition 6 and, for example, only the lower half ( Fig. 4I ) or the upper half ( Fig. 4J ) Will get removed.

- a value of 1, 2, 3, 4 or 5 has proven particularly useful for the number of openings.
- the partition walls 6 provided with openings 22 can of course also be combined with external ventilation devices 21. It is also possible to combine different opening shapes 22 with each other.
- FIG. 9 a venting device is shown, which is designed as an expression 37 in the upper wall 39 of the upper coolant box 4.

- side walls not shown here are arranged, so that there is a total trough-like design of the baffle plate 23.
- This flow E depends on the coolant throughput through the radiator 1.
- a large coolant flow rate 1 results in a relatively high pressure difference between the flow 9 and return 10 and thus between the front part 7 and the rear part 8 of the upper coolant tank 4, which would have a correspondingly high throughput through the recess 22 to result.
- This high throughput can be alleviated by the described hydrodynamic effect become.
- the throughput through the recess 22 can be reduced, and thus, in particular, the speed of passing gas and / or coolant can be reduced. This can in particular have a noise-reducing effect.

- a further flow-limiting device in the form of a flange or a projection 26 is shown, at the lower end 27 of a venting device 28 is formed.
- advantages may arise, in particular due to the hydrodynamic effect which may occur, as described above.
- the projection 26 may possibly be produced in a particularly simple and cost-effective manner by deforming material processing of the partition wall 6.
- FIG. 7 is another conceivable embodiment of a flow-limiting device in the form of a centrally arranged with a recess (not visible in the figure) tube 29.
- the tube 29 is present in the form of a "twisted S" bent so that the inlet 31 horizontally, the outlet 32nd the tube 29, however, is vertical, so that hydrodynamic effects can be used particularly advantageous.
- a holding web 30 may be provided for the tube 29.
- FIG. 8 Finally, a part of a cooling circuit is still sketched, in which an external ventilation device 21 is provided, which is presently arranged at the (possibly local) highest point 33 of the cooling circuit.
- the radiator 1 may be connected in any manner with (eg FIGS. 4B to 4L ) or without (according to FIG. 4A ) Inner venting devices may be formed.
- the external venting device 21 has in the present embodiment shown via a thin connecting channel 36 which connects the flow line 34 with the return line 35.
- the flange can - as usual with radiators - even at a smaller distance, such as at a distance of 10-50 mm, be arranged by the radiator.
- the flange may also be integrated in the radiator. As a rule, only the distance between the forward and / or return opening 15, 16 and the connecting channel 36 is essential.

Description
Die Erfindung betrifft einen Wärmetauscher für zumindest ein Wärmetransportmedium, wie er beispielsweise als Heizkörper zur Erwärmung in den Fahrzeuginnenraum eines Kraftfahrzeuges einströmender Luft verwendet wird. Die Erfindung betrifft weiterhin einen Kühlmittelkreislauf sowie eine Luftbehandlungsvorrichtung für Kraftfahrzeuge unter Verwendung eines solchen Wärmetauschers.The invention relates to a heat exchanger for at least one heat transport medium, as used for example as a radiator for heating in the vehicle interior of a motor vehicle incoming air. The invention further relates to a coolant circuit and an air treatment device for motor vehicles using such a heat exchanger.
Wärmetauscher werden unter anderem in Kraftfahrzeugen für unterschiedliche Aufgaben verwendet. Beispielsweise werden Wärmetauscher zur Motorkühlung in weiterem Sinn z. B. als Kühlmittelkühler, Ölkühler, Abgaskühler und Ladeluftkühler verwendet. Ein weiteres übliches Einsatzgebiet von Wärmetauschern bei Kraftfahrzeugen ist die Temperierung der in den Fahrgastinnenraum zugeführten Luft. Hier werden Wärmetauscher z. B. in Form von Verdampfern, Kondensatoren (bzw. Gaskühlern), inneren Wärmetauschern sowie Heizkörpern verwendet.Heat exchangers are used, inter alia, in motor vehicles for different tasks. For example, heat exchangers for engine cooling in a broader sense z. B. used as a coolant radiator, oil cooler, exhaust gas cooler and intercooler. Another common application of heat exchangers in motor vehicles is the temperature of the air supplied into the passenger compartment. Here are heat exchangers z. B. in the form of evaporators, condensers (or gas coolers), internal heat exchangers and radiators used.
Derartige Wärmetauscher existieren mittlerweile in unterschiedlichsten Bauformen und Einbauarten. Wenn bei Wärmetauschern wenigstens ein zumindest teilweise flüssiges Wärmetransportmedium verwendet wird, so wie dies z. B. bei Kühlmittelkühlern oder Heizkörpern der Fall ist, stellt sich ggf. das Problem von Luftansammlungen im Wärmetauscher, die ggf. den Durchsatz bzw. die gleichmäßige Verteilung des Wärmetransportmediums im Wärmetauscher negativ beeinflussen können. Dies gilt insbesondere bei stehend eingebauten Wärmetauschern.Such heat exchangers now exist in a wide variety of designs and types of installation. If at least one at least partially liquid heat transport medium is used in heat exchangers, as it is z. As is the case with coolant radiators or radiators, if necessary, the problem of air accumulation in the heat exchanger, which may possibly adversely affect the throughput or the uniform distribution of the heat transfer medium in the heat exchanger. This is especially true for standing installed heat exchangers.
Um einen hohen und möglichst gleichmäßigen Durchsatz des Wärmetransportmediums sicherzustellen, kann es sich daher als erforderlich erweisen, sich ggf. im Wärmetauscher ansammelnde Luft abzuführen. Dazu fanden bislang unterschiedliche Vorgehensweisen Verwendung.In order to ensure a high and as even as possible throughput of the heat transport medium, it may therefore prove necessary to dissipate possibly accumulating in the heat exchanger air. To date, different approaches have been used.
Eine Möglichkeit besteht darin, den Wärmetauscher beispielsweise durch eine flache Einbaulage oder eine entsprechende Anordnung von Vorlauf bzw. Rücklauföffnungen derart einzurichten, dass sich im Wärmetauscher ansammelnde Luft aus dem Wärmetauscher entweichen kann bzw. sich z.B. beim Stillstand der Anlage gar nicht erst ansammelt. Ein Problem bei derartigen eingerichteten Wärmetauschern ist, dass bestimmte Einbauweisen (wie z. B. ein stehender Einbau des Wärmetauschers) bzw. bestimmte Ausbildungen der Zuführöffnungen für das Wärmetransportmedium de facto ausgeschlossen sind. Dies ist jedoch gerade bei Kraftfahrzeugen oftmals problematisch, da der Bauraum im vorderen Teil des Kraftfahrzeugs in der Regel sehr eng bemessen ist und gewisse Konfigurationen des Wärmetauschers aufgrund der sonstigen Motorraumbaugruppen teilweise nicht vermeidbar sind.One possibility is to set up the heat exchanger, for example by means of a flat installation position or a corresponding arrangement of flow or return openings, in such a way that air accumulating in the heat exchanger can escape from the heat exchanger or can be removed, for example. when the system is not even accumulated. A problem with such established heat exchangers is that certain installation methods (such as, for example, vertical installation of the heat exchanger) or specific designs of the supply openings for the heat transport medium are in fact excluded. However, this is often problematic especially in motor vehicles, since the space in the front part of the motor vehicle is usually very tight and certain configurations of the heat exchanger due to the other engine compartment modules are partially unavoidable.
Eine weitere Lösungsmöglichkeit besteht darin, ein gewisses Maß an Luftansammlungen im Wärmetauscher zuzulassen und darauf zu vertrauen, dass bei einem gewissen Durchsatz an Wärmetransportmedium die Gasansammlungen im Wärmetauscher vom Wärmetransportmedium durch den Wärmetauscher hindurch mitgerissen werden. Problematisch ist es dabei, dass insbesondere bei geringen Durchsätzen an Wärmetransportmedium die Effektivität des Wärmetauschers durch die Luftansammlung sowohl von der absoluten Leistung aus gesehen als auch von der Gleichmäßigkeit der Wärmeabgabe herabgesetzt sein kann. Insbesondere Letzteres kann zu thermische Verspannungen führen und aufgrund der ungleichen Wärmeverteilung auf der Heizkörperoberfläche vor allen Dingen bei der Behandlung von Luft für den Fahrgastinnenraum nachteilig sein. Ein weiteres Problem besteht darin, dass die Heizkörper aufgrund der Gasansammlungen zur Geräuschbildung neigen, was vor allen Dingen bei im Fahrzeuginnenraum angeordneten Komponenten (wie beispielsweise beim Heizkörper einer Klimaanlage) von Nachteil ist.Another possible solution is to allow a certain amount of air accumulation in the heat exchanger and to rely on the fact that at a certain throughput of heat transfer medium, the gas collections are entrained in the heat exchanger from the heat transfer medium through the heat exchanger. The problem here is that in particular at low throughputs of heat transport medium the Efficiency of the heat exchanger can be reduced by the accumulation of air from both the absolute performance as well as the uniformity of heat dissipation. In particular, the latter can lead to thermal stresses and be disadvantageous due to the uneven heat distribution on the radiator surface, especially in the treatment of air for the passenger compartment. Another problem is that the radiators tend to cause noise due to the accumulation of gas, which is disadvantageous in particular with components arranged in the vehicle interior (such as, for example, in the case of the radiator of an air conditioning system).
Schließlich wurde bereits vereinzelt vorgeschlagen, benachbart zum Rücklauf kleine Entlüftungsöffnungen vorzusehen, so dass sich im Wärmetauscher ansammelndes Gas durch diese Entlüftungsöffnungen hindurch treten und somit den Wärmetauscher verlassen kann. Derartige Entlüftungsöffnungen können den Wärmetauscher jedoch oftmals nur teilweise entlüften. Darüber hinaus neigen derartige Eritlüftungsöffnungen zur Geräuschbildung, was insbesondere bei Wärmetauschern, die im Fahrzeuginnenraum bzw. benachbart zum Fahrzeuginnenraum angeordnet sind (wie beispielsweise bei Heizkörpern) von Nachteil ist.Finally, it has already been proposed in isolated cases to provide small ventilation openings adjacent to the return, so that gas accumulating in the heat exchanger can pass through these ventilation openings and thus leave the heat exchanger. However, such vents can often vent the heat exchanger only partially. In addition, such Eritlüftungsöffnungen tend to noise, which is particularly in heat exchangers, which are arranged in the vehicle interior or adjacent to the vehicle interior (such as radiators) is disadvantageous.
Die
Die vorliegende Erfindung setzt es sich daher zur Aufgabe, einen Wärmetauscher mit wenigstens einer Entlüftungsvorrichtung derart weiterzubilden, dass die bekannten Probleme bei nach dem Stand der Technik bekannten Wärmetauschern zumindest zum Teil beseitigt oder wenigstens gemindert werden. Insbesondere macht es sich die Erfindung zur Aufgabe, einen Wärmetauscher vorzuschlagen, der einfach und kostengünstig in Aufbau und Herstellung ist, und dennoch eine möglichst weitgehende Entlüftung ermöglicht, ohne dass ein Übermaß an unerwünschten Geräuschen auftritt.The present invention is therefore based on the object, a heat exchanger with at least one venting device such that the known problems in known prior art heat exchangers are at least partially eliminated or at least mitigated. In particular, it makes the invention the task, a To propose heat exchangers, which is simple and inexpensive to design and manufacture, and still allows the greatest possible ventilation without an excess of unwanted noise occurs.
Die Vorrichtungen gemäß des unabhängigen Anspruchs lösen diese Aufgaben.The devices according to the independent claim solve these objects.
Dabei wird vorgeschlagen, einen Wärmetauscher für zumindest ein Wärmetransportmedium mit wenigstens einem Vorlauf, wenigstens einem Rücklauf und wenigstens einer Entlüftungsvorrichtung dahin gehend weiterzubilden, dass die Entlüftungsvorrichtung beabstandet von zumindest einer Rücklauföffnung im Wärmetauscher angeordnet ist. Die Entlüftungsvorrichtung kann insbesondere als Ausnehmung ausgestaltet werden, und wird erfindungsgemäß in einer üblicherweise ohnehin vorhandenen Trennwand des Wärmetauschers ausgeführt, dabei bevorzugt in einem oberen Bereich einer Trennwand. Es hat sich überraschendrrweise gezeigt, dass eine derartige Anordnung der Entlüftungsvorrichtung eine besonders vorteilhafte Entlüftung des Wärmetauschers sicherstellen kann. Bislang wurde angenommen, dass eine Anordnung der Entlüftungsvorrichtungen in unmittelbarer Nähe des Rücklaufs von Vorteil ist, da dadurch die Gasansammlungen besonders effektiv abgesaugt werden können. Unerwarteterweise ist dies jedoch nicht der Fall, da sich oftmals auch Gasansammlungen bilden können, die beabstandet zum Rücklauf des Wärmetauschers liegen. Durch die vorgeschlagene Anordnung der Entlüftungsvorrichtung kann es ermöglicht werden, dass auch derartige Gasansammlungen wirksam entfernt werden. Von Vorteil ist es dabei, wenn zumindest in den Bereichen, in denen eine besonders große Gasansammlung auftritt jeweils wenigstens eine Entlüftungsvorrichtung vorgesehen wird.It is proposed to further develop a heat exchanger for at least one heat transport medium with at least one flow, at least one return and at least one venting device, that the venting device is spaced from at least one return opening in the heat exchanger. The venting device can in particular be designed as a recess, and according to the invention is embodied in a partition wall of the heat exchanger which is normally present anyway, preferably in an upper region of a partition wall. It has surprisingly been shown that such an arrangement of the ventilation device can ensure a particularly advantageous ventilation of the heat exchanger. Up to now it has been assumed that an arrangement of the venting devices in the immediate vicinity of the return line is advantageous since it allows the gas accumulations to be sucked off particularly effectively. Unexpectedly, however, this is not the case, since often also gas accumulations can form, which are at a distance from the return of the heat exchanger. The proposed arrangement of the venting device, it may be possible that such gas accumulations are effectively removed. It is advantageous if at least in the areas in which a particularly large gas accumulation occurs in each case at least one venting device is provided.
Es ist bevorzugt, die Entlüftungsvorrichtung auch beabstandet zu zumindest einer Vorlauföffnung im Wärmetauscher auszubilden. Bei dieser vorgeschlagenen Ausführungsform kann zusätzlich zum eigentlichen Durchlauf des Wärmetransportmediums durch den Wärmetauscher eine Art zusätzlicher "Entlüftungskreislauf" vor allem im oberen Teil des Heizkörpers geschaffen werden, der insbesondere durch die kritischen Bereiche des Wärmetauschers hindurch verläuft und dadurch den Wärmetauscher besonders effektiv entlüften kann. Dabei ist selbstverständlich darauf zu achten, dass der Durchsatz dieses zusätzlichen Entlüftungskreislaufs relativ gering gewählt wird, so dass die Leistungsfähigkeit des Wärmetauschers nicht wesentlich abnimmt.It is preferable to also form the ventilation device at a distance from at least one feed opening in the heat exchanger. In this proposed embodiment, in addition to the actual passage of the heat transfer medium through the heat exchanger a kind of additional "vent circuit" are created especially in the upper part of the radiator, which in particular passes through the critical areas of the heat exchanger and thereby vent the heat exchanger particularly effective. It is of course important to ensure that the throughput of this additional vent circuit selected relatively low so that the efficiency of the heat exchanger does not decrease significantly.
Es wird vorgeschlagen, dass der Abstand zwischen zumindest einer Entlüftungsvorrichtung und zumindest einer Vorlauföffnung und/oder zwischen zumindest einer Entlüftungsvorrichtung und zumindest einer Rücklauföffnung zumindest 10 mm, vorzugsweise zumindest 15 mm, besonders vorzugsweise zumindest 20 mm und insbesondere zumindest 25 mm beträgt. Die vorgeschlagenen Werte haben sich als günstig erwiesen. Jedoch sind auch andere Zahlenwerte denkbar. Insbesondere sollen - auch bei sonstigen in dieser Schrift vorkommenden Zahlenangaben - bei (Halb-)Intervallen sowie diskreten Werten sämtliche Zahlenwerte als offenbart und beliebig einsetzbare gelten.It is proposed that the distance between at least one ventilation device and at least one flow opening and / or between at least one ventilation device and at least one return opening is at least 10 mm, preferably at least 15 mm, particularly preferably at least 20 mm and in particular at least 25 mm. The proposed values have proved favorable. However, other numerical values are conceivable. In particular, even with other numerical data occurring in this document, at (half) intervals and discrete values, all numerical values are to be regarded as disclosed and applicable in any desired manner.
Es erweist sich weiterhin als vorteilhaft, wenn zumindest eine Vorlauföffnung und zumindest eine Rücklauföffnung benachbart zueinander angeordnet sind. Dies kann einen kompakten Aufbau und eine einfache Montage, aber auch eine besonders effektive Entlüftung sicherstellen.It also proves to be advantageous if at least one flow opening and at least one return opening are arranged adjacent to one another. This can ensure a compact construction and a simple assembly, but also a particularly effective ventilation.
Weiterhin hat es sich als vorteilhaft erwiesen, wenn zumindest eine Entlüftungsvorrichtung beabstandet von der direkten Verbindungsstrecke zwischen zumindest einer Vorlauföffnung und zumindest einer Rücklauföffnung angeordnet ist. Insbesondere kann es sich als vorteilhaft erweisen, wenn die Entlüftungsvorrichtung möglichst weit von der direkten Verbindungsstrecke zwischen Vorlauföffnung und Rücklauföffnung angeordnet ist. Mit Hilfe der vorgeschlagenen Ausführungsform ist es möglich, ein größeren Teil bzw. im Wesentlichen den gesamten Bereich des Wärmetauschers, in dem sich Gasansammlungen bilden können, von dem bereits erwähnten "Entlüftungskreislauf' durchströmen zu lassen, so dass eine besonders effektive Entlüftung gefördert wird.Furthermore, it has proved to be advantageous if at least one venting device is arranged at a distance from the direct connecting path between at least one feed opening and at least one return opening. In particular, it may prove to be advantageous if the venting device is arranged as far as possible from the direct connection path between the feed opening and the return opening. With the aid of the proposed embodiment, it is possible to allow a larger part or essentially the entire area of the heat exchanger, in which gas accumulations can form, to flow through the already mentioned "venting circuit", so that a particularly effective venting is promoted.
Es hat sich gezeigt, dass die Erfindung besonders vorteilhaft im Zusammenhang mit stehend angeordneten Wärmetauschern mit vorteilhafterweise zumindest einem, vorzugsweise oben liegenden Kühlmittelkasten angewendet werden kann. Insbesondere bei solchen Wärmetauschern kommt es leicht zu Gasansammlungen, die unter Verwendung der vorliegenden Erfindung besonders effektiv beseitigt werden können.It has been found that the invention can be used particularly advantageously in connection with vertically arranged heat exchangers with advantageously at least one, preferably overhead, coolant box. Particularly in such heat exchangers, gas accumulations are easily generated, which can be eliminated particularly effectively using the present invention.
Es hat sich ferner gezeigt, dass die Erfindung besonders effektiv im Zusammenhang mit Wärmetauschern ist, die eine UT-Ablenkung aufweisen und/oder als Heizkörper ausgebildet sind. Eine UT-Ablenkung ist eine so genannte unten erfolgende Ablenkung des Wärmetransportmediums in der Tiefe. Die "Tiefe" bezieht sich dabei auf die Durchströmrichtung des zweiten Fluids, wie insbesondere zu erwärmender Luft für einen Fahrzeuginnenraum.It has also been shown that the invention is particularly effective in connection with heat exchangers, which have a UT deflection and / or are formed as a radiator. A UT deflection is a so-called downward deflection of the heat transport medium in depth. The "depth" refers to the direction of flow of the second fluid, in particular air to be heated for a vehicle interior.
Eine besonders günstige Ausbildung der vorgeschlagenen Erfindung ergibt sich, wenn wenigstens eine Entlüftungsvorrichtung in Form einer oder mehrerer Öffnungen ausgebildet ist.A particularly advantageous embodiment of the proposed invention results when at least one venting device is designed in the form of one or more openings.
As vorteilhaft haben sich dabei ein bis zwei Öffnungen, ggf. auch drei, vier, fünf oder auch mehr Öffnungen erwiesen. Die Öffnungen können dabei eine beliebige Form aufweisen. Bewährt haben sich dabei kreisförmige, halbkreisförmige, linsenförmige, quadratische, rechteckige, konkave, halblinsenförmige und/oder schlitzartige (jeweils horizontal, vertikal und/oder schräg geführt) Ausnehmungen. Als typische Größen haben sich Maße bis 5 mm, vorzugsweise 1 bis 4 mm, besonders vorzugsweise 2 bis 3 mm bewährt. Insbesondere bei Schlitzen können jedoch auch Längen von 5 bis 15 mm, vorzugsweise 6 bis 12 mm, insbesondere 8 bis 10 mm sich als günstig erweisen.One or two openings, possibly also three, four, five or even more openings, have proved to be advantageous. The openings can have any shape. Circular, semicircular, lenticular, square, rectangular, concave, semi-lenticular and / or slot-like recesses (in each case horizontally, vertically and / or obliquely guided) have proved to be useful. Dimensions of up to 5 mm, preferably 1 to 4 mm, particularly preferably 2 to 3 mm, have proven to be typical sizes. However, in particular in the case of slits, lengths of 5 to 15 mm, preferably 6 to 12 mm, in particular 8 to 10 mm, may prove to be favorable.
Möglich ist es auch, die Öffnungen als Ausprägung zu gestalten, welche vorteilhaft in einem Kühlmittelkasten, vorzugsweise in einem oben liegenden Kühlmittelkasten des Wärmetauschers ausgebildet ist. Die Öffnungen sind dabei besonders bevorzugt in einem Kontaktbereich zwischen Trennwand und Kühlmittelkastenwand, insbesondere in einem oben liegenden Bereich des Kühlmittelkastens vorgesehen. Auch kann sich die Öffnung im Bereich einer gegebenenfalls vorhandenen Verbindungsnaht des Kühlmittelkastens befinden. Durch diese Ausbildung ist es möglich, dass Fertigungsschritte eingespart werden können und ggf. unnötige Materialbelastungen verringert werden können. Selbstverständlich ist auch eine Kombination von einer als Ausprägung und einer als Ausnehmung gestalteten Öffnung möglich, insbesondere wenn diese derart benachbart zueinander liegen, dass sich der gemeinsame Öffnungsquerschnitt vergrößert.It is also possible to make the openings as an expression, which is advantageously formed in a coolant box, preferably in an overhead coolant box of the heat exchanger. The openings are particularly preferably provided in a contact region between the partition wall and the coolant box wall, in particular in an overhead region of the coolant box. Also, the opening may be located in the region of an optionally existing connecting seam of the coolant box. With this design, it is possible that manufacturing steps can be saved and possibly unnecessary material loads can be reduced. Of course, a combination of an opening designed as an expression and a recess is also possible, in particular if these are adjacent to one another such that the common opening cross-section increases.
Eine weitere vorteilhafte Bauform kann sich ergeben, wenn wenigstens eine Entlüftungsvorrichtung zumindest eine Strömungsbegrenzungseinrichtung aufweist, welche insbesondere als Prallplatte, als Rohr, als angeformter Flansch und/oder als hydrodynamische Strömungsbegrenzungseinrichtung ausgebildet wird. Ganz allgemein sollten die vorgeschlagenen Heizkörper zumindest in Bereichen, in denen es zu Gasansammlungen kommen kann, möglichst keine scharfen Kanten und sonstige Baugeometrien aufweisen, die zu unerwünschten Geräuschen führen können. Durch die vorgeschlagenen Weiterbildung können die Geräusche nochmals vermindert werden, indem die auftretenden Strömungen insbesondere von der Geschwindigkeit und/oder vom Durchsatz her verringert werden können. Unter hydrodynamischer Strömungsbegrenzungseinrichtung sind ganz allgemein Einrichtungen zu verstehen, bei denen ein hydrodynamischer Staudruck des durch den Wärmetauscher hindurch fließenden Wärmetransportmediums zur Begrenzung anderer Strömungspfade, insbesondere des durch die Entlüftungsvorrichtungen hindurchströmenden Materials, verwendet wird.A further advantageous design may result if at least one ventilation device has at least one flow-limiting device, which is designed in particular as a baffle plate, as a tube, as a molded-on flange and / or as a hydrodynamic flow-limiting device. In general, the proposed radiator should, at least in areas where it can lead to gas accumulation, as possible no sharp edges and other construction geometries, which can lead to unwanted noise. The proposed development, the noise can be further reduced by the currents occurring in particular from the speed and / or throughput can be reduced. The term "hydrodynamic flow restricting device" is to be understood quite generally as meaning devices in which a hydrodynamic dynamic pressure of the heat transport medium flowing through the heat exchanger is used to limit other flow paths, in particular of the material flowing through the venting devices.
Weiterhin kann es sich als vorteilhaft erweisen, zumindest eine Entlüftungsvorrichtung als externe Entlüftungsvorrichtung außerhalb des Wärmetauscherkörpers und/oder des Kühlmittelkastens auszubilden. Hier kann die Entlüftungsvorrichtung beispielsweise möglichst weit entfernt vom Fahrgastinnenraum bzw. in Bereichen angeordnet werden, bei denen nur wenige Geräusche entstehen bzw. die entstehenden Geräusche in nur verringertem Ausmaß in den Kraftfahrzeuginnenraum übertragen werden.Furthermore, it may prove to be advantageous to design at least one ventilation device as an external ventilation device outside the heat exchanger body and / or the coolant reservoir. Here, the venting device can for example be arranged as far away from the passenger compartment or in areas where only a few noises occur or the resulting noise is transmitted to a reduced extent in the motor vehicle interior.
Denkbar ist es in diesem Zusammenhang, zumindest eine externe Entlüftungsvorrichtung in einem ggf. gesondert ausgebildeten Flanschbereich vorzusehen. Dieser Flanschbereich kann beispielsweise mit einem gewissen Abstand zum Wärmetauscher in der Vorlauf- bzw. Rücklaufleitung vorgesehen werden. Bei Heizkörpern ist dieser Abstand zwischen Flansch und Heizkörper - und damit der Abstand der Entlüftungsvorrichtung zum Heizkörper - in der Regel relativ klein, und beträgt üblicherweise 10-50 mm, z.B. 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm oder 50 mm.It is conceivable in this context to provide at least one external ventilation device in a possibly separately formed flange region. This flange region can be provided for example with a certain distance from the heat exchanger in the flow or return line. For radiators, this distance between flange and radiator - and thus the distance of the venting device to the radiator - is usually relatively small, and is usually 10-50 mm, e.g. 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm or 50 mm.
Weiterhin wird vorgeschlagen, einen Kühlmittelkreislauf mit wenigstens einem Wärmetauscher gemäß einem der vorgeschlagenen Ausführungsformen zu versehen. Der Kühlmittelkreislauf weist die entsprechenden Vorteile in analoger Form auf.Furthermore, it is proposed to provide a coolant circuit with at least one heat exchanger according to one of the proposed embodiments. The coolant circuit has the corresponding advantages in analog form.
Auch wird vorgeschlagen, eine Luftbehandlungsvorrichtung für Kraftfahrzeuge mit zumindest einem Wärmetauscher gemäß einem der vorgenannten Ausbildungsformen zu versehen. Die Luftbehandlungsvorrichtung, die beispielsweise zusätzlich einen Verdampfer zur Abkühlung von einströmender Luft aufweisen kann, weist dann die beschriebenen Vorteile in analoger Form auf.It is also proposed to provide an air treatment device for motor vehicles with at least one heat exchanger according to one of the aforementioned embodiments. The air treatment device, which may, for example, additionally comprise an evaporator for cooling incoming air, then has the described advantages in an analogous form.
Von Vorteil ist es darüber hinaus einen Wärmetauscher, einen Kühlmittelkreislauf oder eine Luftbehandlungsvorrichtung nach einer der vorab beschriebenen Ausbildungsmöglichkeiten dahin gehend weiterzubilden, dass zumindest eine Entlüftungsvorrichtung bezogen auf zumindest eine Baugruppe des Wärmetransportmediumkreislaufs und/oder bezogen auf den gesamten Wärmetransportmediumkreislauf im Bereich einer geodätisch lokal hochgelagerten und/oder im Wesentlichen im Bereich der geodätisch höchstgelagerten Stelle auszubilden. Die vorgeschlagene Vorrichtung kann in diesem Fall besonders effektiv ausgebildet werden.It is also advantageous to further develop a heat exchanger, a coolant circuit or an air treatment device according to one of the above-described training possibilities that at least one venting device based on at least one assembly of the heat transport medium circuit and / or related to the entire heat transport medium cycle in the region of a geodetically locally high-level and / or essentially in the area of the geodesic highest place. The proposed device can be made particularly effective in this case.
