Definitions
- the invention relates to a heat exchanger for cooling a cooling medium, in particular in an electrical / electronic device.
- Such a heat exchanger is eg off JP-A-09 283 959 known.
- this object is achieved by the subject matter of claim 1.
- the risk of coolant escaping and causing damage to the electronics is reduced.
- the hollow volume of the cooling circuit automatically adapts to the variable volume of the cooling medium, which is located in the cooling circuit, so that regardless of the operating position of the heat exchanger, the formation of gas bubbles in the cooling medium is prevented. This allows safe cooling even after the heat exchanger has temporarily occupied an unusual operating position, for example during transport.
- a particularly preferred embodiment of such a heat exchanger is the subject of claim 26. With very low cost, it prevents problems and damage due to impurities in the cooling medium.
- Fig. 1 schematically shows a heat exchanger 20. This has in a known manner flat cooling tubes 22 which are flowed through during operation of a cooling medium 24 and which are connected in a heat-conducting manner with zigzag arranged cooling plates 26.
- the upper tank 30 is liquid-tightly connected to the heat exchanger 20 by means of a flare connection 44. He has an upper wall 46 ( Fig. 3 ), which are here in one piece with the partition wall 32 is formed. In it are recesses, namely a recess 48 above the drain-side space 36 and a recess 50 above the inflow-side space 34th
- a flexible membrane 54 on which rests a flat spring assembly 56 made of stainless spring steel.
- This spring assembly 56 is connected to the membrane 54, e.g. by vulcanization.
- the spring assembly 56 may also be vulcanized into the membrane 54 in order to protect it particularly well against corrosion.
- the membrane 54 and the spring assembly 56 are held at its outer edge by the edge 58 of a cover 60 fluid-tight. Likewise, they are held firmly in the middle by a web 61 of the lid 60, vg. Fig. 3 , In the space 62 between the lid 60 and the membrane 54 is air or an inert gas, such as nitrogen.
- the upper tank 30 has an inlet 64, and through this cooling medium 24 flows in the direction of an arrow 66 to the inlet-side chamber 34. From there it flows through the local pipes 22 to the lower tank 40, and from there by the in Fig. 1 left hand pipe 22 up to the drain-side chamber 36. Naturally, in some cases, the flow direction may be reversed.
- the cooling medium flows through a drain 68 in the direction of an arrow 70 to a heat sink 74, which is in heat conductive connection with an electronic component 76 which is disposed on a printed circuit board 78 and is powered by these.
- the cooling medium is heated, and the heated cooling medium is fed back to the inlet 66 by a driven by an electric motor 80 circulating pump 82.
- the heat exchanger 20 is cooled by means of a fan 84 by air, which is indicated only very schematically.
- Fig. 5 to 7 show the structure of the spring assembly 56. This is formed by the fact that in a thin sheet of spring steel, a left spiral recess 90 and a right spiral recess 92 are incorporated, whereby on the left a larger coil spring 94 is formed, which the larger chamber 36th is assigned, and on the right a smaller coil spring 96 which is associated with the smaller chamber 34.
- the chambers 34, 36 are filled up to the membrane 54 with cooling medium 24. If this expands, the membrane 54 bulges above the recesses 48, 50 upwards, whereby the springs 94, 96 prevent the membrane 54 from being bulged and damaged at individual points.
- the membrane 54 bulges downward through the recesses 48, 50, whereby the springs 94, 96 also provide a uniform deflection.
- Fig. 8 shows a surge tank 110, which has only a single port 112 through which during operation coolant flows or flows.
- the container 110 has at the bottom a pot 114, at the upper end of an outwardly projecting flange 116 is provided, in which an annular groove 118 is located. In this engages a belonging to an elastic membrane 121 sealing bead 120, which is pressed by a cover 122 sealingly into the annular groove 118.
- the attachment of the lid 122 on the pot 114 as known, not shown.
- the elastic membrane 121 is pressed in the manner shown in the middle by a spring 124 acted upon by a plunger 126 down. Above the plunger 126 protrudes through an opening 128 in the lid 122 and is there provided with a scale 130 for pressure indication. This plunger 126 facilitates venting, e.g. after a repair. Again, the space below the membrane 121 is completely filled with coolant, ie without air bubbles.
- Fig. 9 to 12 show a second, preferred embodiment of the invention. Same or equivalent parts as in the Fig. 1 to 8 are usually denoted by the same reference numerals as there and will not be described again.
- Fig. 9 shows an overview picture analog Fig. 1 .
- the heated cooling fluid from the heat receiver 74 is via a line 66 to the inlet 64 of the heat exchanger 120 supplied, where it is cooled. From the outlet 68, it flows via a line 70 to a unit 140.
- the fan and the circulation pump are driven by the same electric motor, cf. eg the WO2004 / 031588A1 the applicant.
- the cooling channels 22, cooling plates 26, etc. are the same structure as in the first embodiment of the Fig. 1 to 8 ,
- the heat exchanger tank 130 is made as a molded piece of a thermoplastic material by injection molding.
- This tank 130 has an inwardly projecting flange 48, and on top of this flange 48 is molded a flexible membrane 154 of TPE (thermoplastic elastomer) as a soft component in a second injection molding step. This process is also referred to as 2K injection molding.
- TPE thermoplastic elastomer
- the weld is designated 155.
- the membrane 154 are preferably thermoplastic silicone elastomers, which build on a two-phase block copolymer (polydimethylsiloxane urea copolymer). Possibly.
- a TPE-A polyether block amide
- a TPE-A polyether block amide
- the cover 60 is used as an additional security, which has a downwardly projecting portion 58, which in the area 156, so along the entire periphery of the diaphragm 154, rests with pressure on the welded edge of the diaphragm 154.
- the outer edge 158 of the lid 60 is connected to the upper edge 160 of the tank 130, for example by laser welding, gluing, screwing, or by a latching connection.
- Fig. 12 shows a connection by means of a notch 166 and a projecting edge 168, which are connected by laser welding.
- laser welding results in the space 162 between the cover 60 and the diaphragm 154 is a closed air cushion, which supports the diaphragm 154 upwards and thereby mechanically relieved.
- polyphenyloxid (PPO) glass fiber reinforced, possibly also polypropylene (PP), also glass fiber reinforced.
- PPS polyphenylene sulfide
- PA-HTN a temperature stabilized polyamide
- PA is very good for a laser welding, PPS a little less good. If suitable, therefore, PA is preferred, also for reasons of price.
- the heat exchanger 120 can also work as a surge tank to compensate for changes in volume of the coolant, as they are inevitable after prolonged operation and as they can also occur due to temperature fluctuations.
- FIG. 13 shows a heat exchanger 120 'with integrated filter 170.
- this filter has 170 filter openings 172 z. B. on the inlet side 36 (in Fig. 13 right) may be larger than on the drain side 34 to first achieve coarse filtering and then fine filtering.
- the part of the filter 170 that performs the coarse filtering could also be called a sieve.
- the filter 170 may be made of metal or plastic and is according to Fig. 15 attached to the underside of the container 130 ', e.g. B. in two-component injection molding.
- Fig. 16 shows an alternative in which the filter 170 is connected to the seal 44a to form a structural unit. This can be achieved, for example, by vulcanization. Alternatively, and particularly inexpensively, it is possible, for example, to overmold the filter 170 by injection molding with TPE. In both cases, the assembly is simplified, and you get a very robust heat exchanger.
- the filter 170 filters cooling medium, which flows via the inlet 64 into the container 130 'and from there into the flat tubes 22 of the heat exchanger 20 downwards. As a result, coarse dirt is retained on the right part of the filter 170.
- the cooling medium flows through the left half of the flat tubes 22 from bottom to top, where it is filtered by the left half of the filter 170, so that through the drain 68 coolant to the pump 140 (FIGS. Fig. 9 ), which is doubly filtered.
- the resulting machining chips can not be completely removed without reducing the efficiency of the heat absorber 74.
- the invention avoids such problems. It is particularly advantageous that one obtains a large filter area by the invention and can thus avoid an additional filter housing.
- chips and dirt particles which dissolve in the heat receiver and in the heat exchanger are reliably retained on the filter 170 on the downstream side before they flow into the pump 140.
- the large filter area in relation to the accumulated amount of dirt prevents clogging of the filter and excessive pressure drop of the cooling medium in the circuit.
- the invention thus avoids the need to provide a separate filter housing including hose connections, which saves costs. Also, no space for a separate filter housing and the necessary hose connections is needed, allowing a compact design. Finally, chips which dissolve out of the heat absorber 74 and the heat exchanger 20, in the illustrated arrangement of the filter, namely in the heat exchanger tank, not get into the pump 140, because this is arranged in the flow direction behind the heat exchanger 20 and in front of the heat absorber 74. Also, at no other point in the overall system, the filter surface could be made so large without significant additional costs. Clogging of the fine structures of the heat absorber 74 is therefore easily avoided or severely hampered, as is blocking the circulation pump 140.
- Fig. 17 shows a sectioned detail of the filter 170 and the seal 44a Fig. 16 , When mounting the filter 170 in the heat exchanger 20, the seal 44a is preferably deformed to effect a good seal.
- Fig. 16 When mounting the filter 170 in the heat exchanger 20, the seal 44a is preferably deformed to effect a good seal.

Abstract
Description
Die Erfindung betrifft einen Wärmetauscher für die Kühlung eines Kühlmediums, insbesondere in einem elektrischen/elektronischen Gerät.The invention relates to a heat exchanger for cooling a cooling medium, in particular in an electrical / electronic device.
In einem mit Kühlmedium gefüllten, geschlossenen Kühlsystem kommt es bei Temperaturänderungen und auch durch Permeation, z.B. durch Schlauchwände, zu einer Volumenänderung des Kühlmediums. Für diese muss ein Ausgleich gefunden werden, der dafür sorgt, dass im System keine oder nur geringe Druckänderungen auftreten.In a closed cooling system filled with cooling medium, temperature changes and also permeation, e.g. through tube walls, to a volume change of the cooling medium. For these a balance must be found, which ensures that in the system little or no pressure changes occur.
Derartige Volumenänderungen können mittels eines so genannten Ausgleichsbehälters gepuffert werden. Dieser verursacht aber zusätzliche Kosten und erhöht auch das Risiko, dass Kühlmedium nach außen leckt.Such volume changes can be buffered by means of a so-called surge tank. However, this causes additional costs and also increases the risk that cooling medium leaks to the outside.
Ein derartiger Wärmetauscher ist z.B. aus
Ein wichtiges Problem bei Wärmetauschern für elektronische Geräte ist, dass deren exakte Betriebslage nicht im Voraus bekannt ist. Das gilt nicht zuletzt für den Transport zum Kunden, weil solche Kühlsysteme bereits beim Hersteller mit Kühlmedium gefüllt werden und man nicht voraussagen kann, welche Lage sie beim Transport einnehmen werden. Ebenso gilt das bei der Verwendung in Fahrzeugen aller Art (Flugzeuge, Schiffe, Landfahrzeuge, Fahrzeuge im Zustand der Schwerelosigkeit). Deshalb muss die Betriebssicherheit in allen denkbaren Betriebslagen gewährleistet sein. Würde sich im Kühlkreislauf Flüssigkeit mit Gas vermischen, so wäre ein sicherer Betrieb einer Umwälzpumpe nicht mehr gewährleistet, wodurch die Kühlleistung rapide abnehmen könnte. Das würde dann sehr rasch dazu führen, dass das zu kühlende elektronische Bauteil entweder sich selbst abschaltet, oder durch den Temperaturanstieg zerstört wird.An important problem with heat exchangers for electronic devices is that their exact operating position is not known in advance. This applies not least to the transport to the customer, because such cooling systems are already filled with cooling medium at the manufacturer and one can not predict which position they will occupy during transport. The same applies to the use in vehicles of all kinds (aircraft, ships, land vehicles, vehicles in the state of weightlessness). Therefore, the operational safety must be guaranteed in all conceivable operating situations. If liquid were mixed with gas in the cooling circuit, safe operation of a circulating pump would no longer be guaranteed, as a result of which the cooling capacity could decrease rapidly. This would then very quickly lead to the electronic component to be cooled either switching itself off or being destroyed by the rise in temperature.
Es ist deshalb eine Aufgabe der Erfindung, einen neuen Wärmetauscher bereit zu stellen.It is therefore an object of the invention to provide a new heat exchanger.
Nach der Erfindung wird diese Aufgabe gelöst durch den Gegenstand des Anspruchs 1. Hierdurch ergibt sich eine kompakte und preiswerte Anordnung. Das Risiko, dass Kühlmedium austreten und Schäden an der Elektronik verursachen kann, wird reduziert. Und durch die mindestens eine flexible Membran wird erreicht, dass sich das Hohlvolumen des Kühlkreislaufs automatisch an das variable Volumen des Kühlmediums anpasst, das sich im Kühlkreislauf befindet, so dass unabhängig von der Betriebslage des Wärmetauschers die Entstehung von Gasblasen im Kühlmedium verhindert wird. Dies ermöglicht eine sichere Kühlung auch, nachdem der Wärmetauscher zeitweise eine ungewöhnliche Betriebslage eingenommen hat, z.B. während des Transports.According to the invention, this object is achieved by the subject matter of claim 1. This results in a compact and inexpensive arrangement. The risk of coolant escaping and causing damage to the electronics is reduced. And through the at least one flexible membrane is achieved that the hollow volume of the cooling circuit automatically adapts to the variable volume of the cooling medium, which is located in the cooling circuit, so that regardless of the operating position of the heat exchanger, the formation of gas bubbles in the cooling medium is prevented. This allows safe cooling even after the heat exchanger has temporarily occupied an unusual operating position, for example during transport.
Eine besonders bevorzugte Ausgestaltung eines solchen Wärmetauschers ist Gegenstand des Anspruchs 26. Mit sehr geringen Kosten verhindert sie Probleme und Schäden durch Verunreinigungen im Kühlmedium.A particularly preferred embodiment of such a heat exchanger is the subject of
Durch die bevorzugte Weiterbildung gemäß Anspruch 29 ergibt sich eine kompakte, robuste und Kosten sparende Bauweise.The preferred development according to claim 29 results in a compact, robust and cost-saving design.

Die Räume zwischen den flachen Rohren 22 sind oben durch Verschlussbleche 28 flüssigkeitsdicht verschlossen, so dass ein oberer Tank 30 entsteht, der durch eine vertikale Trennwand 32 in eine zulaufseitige Kammer 34 und eine ablaufseitige Kammer 36 unterteilt ist.The spaces between the

Diese Ausnehmungen 48, 50 sind auf ihrer Oberseite flüssigkeitsdicht verschlossen durch eine flexible Membran 54, auf welcher eine flache Federanordnung 56 aus rostfreiem Federstahl aufliegt. Diese Federanordnung 56 ist mit der Membran 54 verbunden, z.B. durch Vulkanisieren. Hierzu kann die Federanordnung 56 auch in die Membran 54 einvulkanisiert sein, um sie besonders gut vor Korrosion zu schützen.These

Von dort fließt das Kühlmedium durch einen Ablauf 68 in Richtung eines Pfeiles 70 zu einer Wärmesenke 74, die in Wärme leitender Verbindung mit einem elektronischen Bauteil 76 steht, das auf einer Leiterplatte 78 angeordnet ist und über diese mit Strom versorgt wird.From there, the cooling medium flows through a

Dieser Tank 130 hat einen nach innen ragenden Flansch 48, und auf der Oberseite dieses Flanschs 48 ist eine flexible Membran 154 aus TPE (thermoplastischem Elastomer) als Weichkomponente in einem zweiten Spritzgussschritt angespritzt. Man bezeichnet dieses Verfahren auch als 2K-Spritzguss. Die Schweißnaht ist mit 155 bezeichnet.This
Für die Membran 154 eignen sich bevorzugt thermoplastische Silikonelastomere, die auf einem zweiphasigen Block-Copolymer (Polydimetylsiloxan-Harnstoff-Copolymer) aufbauen. Ggf. kann auch ein TPE-A (Polyether-Block-Amid) verwendet werden.For the
Da die Festigkeit der Verbindung zwischen dem thermoplastischen Werkstoff des Tanks 130 und dem angespritzten TPE der Membran 154 im Bereich der Verbindungsnaht 156 nicht allzu groß ist, wird als zusätzliche Sicherheit der Deckel 60 verwendet, der einen nach unten ragenden Abschnitt 58 hat, welcher im Bereich 156, also längs der gesamten Peripherie der Membran 154, mit Pressung auf dem angeschweißten Rand der Membran 154 aufliegt.Since the strength of the connection between the thermoplastic material of the
Zu diesem Zweck ist der äußere Rand 158 des Deckels 60 mit dem oberen Rand 160 des Tanks 130 verbunden, z.B. durch Laserschweißen, Kleben, Schrauben, oder durch eine Rastverbindung.
Wenn zu viel Sauerstoff durch die Kunststoffwände in das Kühlsystem hinein diffundiert, oxidiert es die im Kühlmittel enthaltenen Korrosionsinhibitoren, und es bildet ggf. Gasblasen, was zu Funktionsstörungen im Kühlsystem, ggf. sogar zu einem Ausfall des Kühlsystems, führen kann. Wenn zu viel Kühlmittel durch die Kunststoffwände nach außen diffundiert, ist bei der geforderten Lebensdauer (oft ca. 60.000 Stunden) irgendwann zu wenig Kühlmittel im System übrig, damit dieses noch funktionieren kann, und dann tritt ebenfalls ein Ausfall ein.If too much oxygen diffuses through the plastic walls into the cooling system, it oxidizes the corrosion inhibitors contained in the coolant, and it may form gas bubbles, which can lead to malfunction in the cooling system, possibly even to a failure of the cooling system. If too much coolant diffuses through the plastic walls to the outside, at the required service life (often about 60,000 hours) at some point too little coolant left in the system, so this can still work, and then there is also a failure.
Diese Anforderungen grenzen - neben den Temperatur- und Festigkeitsforderungen - die geeigneten Werkstoffe ein.These requirements limit - in addition to the temperature and strength requirements - the appropriate materials.
Als Grundwerkstoffe (Hartkomponente) für den Tank 130 kommen in Frage: Polyphenyloxid (PPO), glasfaserverstärkt, ggf. auch Polypropylen (PP), ebenfalls glasfaserverstärkt. Besonders geeignet im Hinblick auf die Forderung einer sehr geringen Durchlässigkeit für Wasser, Glykol oder ein sonstiges Kühlmittel vom Kühlkreislauf nach außen einerseits und für Sauerstoff von außen in das Kühlmittel hinein andererseits eignet sich nach dem augenblicklichen Kenntnisstand Polyphenylensulfid (PPS) glasfaserverstärkt, oder PA-HTN, ein temperaturstabilisiertes Polyamid, ebenfalls glasfaserverstärkt.As base materials (hard component) for the
PA eignet sich sehr gut für eine Laserschweißung, PPS etwas weniger gut. Bei Eignung wird deshalb PA bevorzugt, auch aus Preisgründen.PA is very good for a laser welding, PPS a little less good. If suitable, therefore, PA is preferred, also for reasons of price.
Durch die Erfindung erreicht man, dass der Wärmetauscher 120 gleichzeitig auch als Ausgleichsgefäß arbeiten kann, um Volumenänderungen der Kühlflüssigkeit ausgleichen zu können, wie sie nach längerem Betrieb unvermeidlich sind und wie sie auch durch Temperaturschwankungen auftreten können.By the invention it is achieved that the

Anschließend durchströmt das Kühlmedium die linke Hälfte der flachen Rohre 22 von unten nach oben, wobei es von der linken Hälfte des Filters 170 gefiltert wird, sodass durch den Ablauf 68 Kühlmittel zur Pumpe 140 (
Dies ist wichtig, weil die Pumpe 140 sehr empfindlich gegen Verschmutzungen des Kühlmittels ist und deshalb besonders gut geschützt werden muss, denn Verschmutzungen könnten ein Festfressen der Pumpe 140 bewirken.This is important because the
Von der Pumpe 140 fließt das Kühlmittel gemäß
Bedingt durch die große Filterfläche bei dieser innovativen Anordnung wird erreicht, dass der Druckabfall am Filter 170 sehr niedrig wird.Due to the large filter area in this innovative arrangement is achieved that the pressure drop across the
Bei Verwendung eines spanabhebend bearbeiteten Wärmeaufnehmers lassen sich die entstehenden Bearbeitungsspäne nicht restlos entfernen, ohne den Wirkungsgrad des Wärmeaufnehmers 74 zu reduzieren.When using a machined heat absorber, the resulting machining chips can not be completely removed without reducing the efficiency of the
Im Wärmetauscher 20 lassen sich Restspäne und Schmutzpartikel beim Herstellungsprozess ebenfalls nicht vermeiden, sondern allenfalls dadurch reduzieren, dass dieser im Vakuum gelötet und danach aufwändig gespült und gereinigt wird.In the
Der Eintrag von Schmutz in den Kreislauf des Kühlmittels beim Füllen mit Kühlmittel und beim anschließenden Prüfen lässt sich ebenfalls nicht restlos vermeiden.The entry of dirt in the circulation of the coolant when filling with coolant and the subsequent testing can also not be completely avoided.
Die Folge ist, dass Späne und Schmutz die feinen Strukturen im Wärmeaufnehmer verstopfen und dadurch den Wirkungsgrad reduzieren könnten. Auch besteht immer die Gefahr, dass sich Schmutzpartikel in der Pumpe 140 in einen schmalen Spalt setzen und so zum Blockieren der Pumpe führen.The result is that chips and dirt clog the fine structures in the heat absorber and thus could reduce the efficiency. Also always exists the risk that dirt particles in the
Durch die Erfindung vermeidet man solche Probleme. Besonders vorteilhaft ist, dass man durch die Erfindung eine große Filterfläche erhält und so ein zusätzliches Filtergehäuse vermeiden kann. Im Flüssigkeitskreislauf werden Späne und Schmutzpartikel, welche sich im Wärmeaufnehmer und im Wärmetauscher lösen, auf der Abströmseite sicher am Filter 170 zurückgehalten, bevor sie in die Pumpe 140 strömen. Die im Verhältnis zur anfallenden Schmutzmenge große Filterfläche verhindert ein Verstopfen des Filters und einen zu hohen Druckabfall des Kühlmediums im Kreislauf.The invention avoids such problems. It is particularly advantageous that one obtains a large filter area by the invention and can thus avoid an additional filter housing. In the liquid circuit, chips and dirt particles which dissolve in the heat receiver and in the heat exchanger are reliably retained on the
Durch die Erfindung vermeidet man also die Notwendigkeit, ein separates Filtergehäuse einschließlich Schlauchverbindungen vorzusehen, was Kosten spart. Auch wird kein Raum für ein separates Filtergehäuse und die notwendigen Schlauchverbindungen benötigt, was eine kompakte Bauweise ermöglicht. Schließlich können Späne, welche sich aus dem Wärmeaufnehmer 74 und dem Wärmetauscher 20 lösen, bei der dargestellten Anordnung des Filters, nämlich im Wärmetauschertank, nicht in die Pumpe 140 gelangen, weil diese in Strömungsrichtung hinter dem Wärmetauscher 20 und vor dem Wärmeaufnehmer 74 angeordnet ist. Auch könnte an keiner anderen Stelle des Gesamtsystems die Filterfläche ohne wesentliche Mehrkosten so groß gemacht werden. Ein Verstopfen der feinen Strukturen des Wärmeaufnehmers 74 wird deshalb in einfacher Weise vermieden oder stark behindert, ebenso ein Blockieren der Umwälzpumpe 140.The invention thus avoids the need to provide a separate filter housing including hose connections, which saves costs. Also, no space for a separate filter housing and the necessary hose connections is needed, allowing a compact design. Finally, chips which dissolve out of the
Naturgemäß könnte nach dem gleichen Prinzip auch ein Ausgleichsgefäß hergestellt werden, das vom Wärmetauscher getrennt ist, z.B. dann, wenn das Volumen des Wärmetauschers aus Raumgründen beschränkt ist. Auch sonst sind im Rahmen der vorliegenden Erfindung vielfache Abwandlungen und Modifikationen möglich.Naturally, according to the same principle, a compensating vessel which is separate from the heat exchanger, e.g. when the volume of the heat exchanger is limited for reasons of space. Even otherwise, many modifications and modifications are possible within the scope of the present invention.
