Description
Die ständige zunehmende Miniaturisierung elektronischer Bauteile führt zu sehr hohen Leistungs- und Verlustleistungsdichten. Die zulässige Sperrschichttemperatur von Halbleitern bleibt dagegen konstant, so dass hohe Anforderungen an Kühlkörper für die elektronischen Bauteile gestellt werden. Im Automobilbereich erreicht die Leistungselektronik inzwischen mehrere Kilowatt, wobei die Verlustleistungen üblicherweise zwischen 0,4 kW bis 2 kW für eine Baueinheit liegen.The permanent Increasing miniaturization of electronic components leads too much high power and power dissipation densities. The permissible junction temperature of semiconductors, however, remains constant, so high demands on heatsink for the electronic Components are placed. In the automotive sector, the power electronics reaches now several kilowatts, with the power losses usually between 0.4 kW to 2 kW for a unit lie.
Zur Kühlung von Leistungshalbleitern werden häufig Aluminiumstrangpressprofile eingesetzt. Diese sind in ihrem Querschnitt entsprechend konfiguriert und mit mehreren in unterschiedliche Richtungen ragenden Rippen versehen. Darüber hinaus sind Aluminiumträgerplatten bekannt, die zur Oberflächenvergrößerung mit angelöteten Kühlrippen aus dünnen Aluminiumbändern versehen sind. Die Leistungsdichte bezogen auf die nutzbare Kühlfläche ist für viele Anwendungen nicht ausreichend, was teilweise auch an den zu geringen Luftleistungen kühlluftseitig liegt. Auch die Maßnahmen zur Oberflächenvergrößerung durch aufgelötete Rippen erfordert einen kostenintensiven Lötprozess mit der Gefahr der Unebenheit durch Verzug. Dadurch wird die Oberflächenqualität der Kühleinrichtung beeinträchtigt, was wiederum den Wärmefluss behindert.to cooling of power semiconductors are often aluminum extrusion profiles used. These are configured accordingly in their cross section and with several ribs projecting in different directions Mistake. About that In addition, aluminum carrier plates known to be used for surface augmentation soldered cooling fins from thin aluminum strips are provided. The power density related to the usable cooling surface is for many Applications insufficient, which is partly due to the low Air flow on cooling air side lies. Also the measures for surface enlargement soldered Ribs require a costly soldering process with the risk of unevenness by default. This impairs the surface quality of the cooling device, which in turn affects the heat flow with special needs.

Die
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde eine Anordnung zum Kühlen elektronischer Bauelemente zuschaffen, die eine hohe Kühlleistung aufweist und kostengünstig herstellbar ist.Of the The present invention is therefore the object of an arrangement for cooling Electronic components provide a high cooling capacity has and inexpensive can be produced.
Diese Aufgabe wird durch eine Kühlvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a cooling device solved with the features of claim 1.
Als Vorteil der Erfindung ist es anzusehen, dass mit äußerst geringem Aufwand eine wirksame Kühlvorrichtung für elektronische Bauelemente geschaffen ist, und zwar durch die Kombination mit einem ohnehin erforderlichen Wärmetauscher für das Kühlmittel eines Antriebsmotors in einem Kraftfahrzeug. Ein solcher Wärmetauscher verfügt einerseits über eine große wärmeübertragende Oberfläche, wobei diesem Wärmetauscher üblicherweise ein Lüfter zur Erzeugung eines angemessenen Kühlluftstromes zugeordnet ist. Da der Wärmetauscher und der Lüfter zur Erzeugung des Kühlluftstromes ohnehin im Kraftfahrzeug vorhanden sind, ist für die vorliegende Erfindung lediglich die Trägerplatte zur Aufnahme der elektronischen Bauelemente zusätzlich erforderlich, wobei diese Trägerplatte wahlweise an der Außenseite eines Kühlmittelkastens oder an einem Seitenteil des Wärmetauschers befestigt werden kann. Im Falle der Befestigung am Kühlmittelkasten erfolgt die Wärmeabfuhr durch den Kühlmittelstrom, wobei vorzugsweise die Trägerplatte dem abströmseitigen Kühlmittelkasten zugeordnet ist. Mit der erfindungsgemäßen Kühlvorrichtung wird eine hohe Kühlleistung auf kleiner Grundfläche erreicht, wodurch eine ausreichende Wärmeabfuhr gegeben ist.When Advantage of the invention is to be considered that with extremely low Effort an effective cooling device for electronic Components is created, through the combination with a anyway required heat exchanger for the coolant a drive motor in a motor vehicle. Such a heat exchanger has on the one hand over a big heat transfer Surface, where this heat exchanger usually a fan is assigned to generate an adequate cooling air flow. As the heat exchanger and the fan for generating the cooling air flow are present in the motor vehicle anyway, is for the present invention only the carrier plate additionally required for receiving the electronic components, wherein this carrier plate optionally on the outside a coolant box or on a side part of the heat exchanger can be attached. In case of attachment to the coolant box the heat dissipation takes place through the coolant flow, wherein preferably the carrier plate the downstream coolant box assigned. With the cooling device according to the invention is a high cooling capacity on a small footprint achieved, whereby a sufficient heat dissipation is given.
Es ist durchaus denkbar, das Seitenteil des Wärmetauschers selbst als Trägerplatte für die elektronischen Bauelemente auszubilden. In diesem Fall hat das Seitenteil eine Doppelfunktion, nämlich diejenige der Trägerplatte zur Aufnahme der elektronischen Bauelemente und die des Seitenteils als äußeres Versteifungselement, das auch zur Aufnahme von Befestigungsmitteln für den Wärmetauscher dient. Ist das Seitenteil selbst die Trägerplatte, so ist eine unmittelbare stoffschlüssige Verbindung zwischen Trägerplatte und der benachbarten Wellrippe gegeben.It is quite conceivable, the side part of the heat exchanger itself as a support plate for the to train electronic components. In this case, the side panel has a double function, namely that of the carrier plate for receiving the electronic components and the side part as an outer stiffening element, which also serves to accommodate fasteners for the heat exchanger. Is this Side part itself the carrier plate, so is an immediate cohesive connection between the support plate and the adjacent corrugated rib.
Sofern die Trägerplatte ein separates Bauteil ist, das an einem herkömmlichen Seitenteil des Kühlmittelkühlers oder an dessen Kühlmittelkasten befestigt wird, so sind mechanische Verbindungsmittel ebenfalls möglich, bei spielsweise Schrauben oder Nieten. Für den Fall, daß eine möglichst große thermische Entkopplung zwischen dem Kühlmittel im Wärmetauscher und den elektronischen Bauelementen vorhanden sein soll, kann es zweckmäßig sein das Wärmetauscherrohr, welches der Trägerplatte mit den elektronischen Bauelementen benachbart ist, zu verschließen, wobei ein Verschluß an der Einlaufseite für besonders zweckmäßig erachtet wird.Provided the carrier plate is a separate component that on a conventional side part of the coolant radiator or at the coolant box is attached, then mechanical fasteners are also possible, for example, screws or rivets. In the event that one possible size thermal decoupling between the coolant in the heat exchanger and the electronic components should be present, it can be useful that Heat exchanger tube which of the support plate with adjacent to the electronic components to close, wherein a lock on the inlet side for particularly appropriate becomes.
