Description
Die Erfindung betrifft eine Vorrichtung zur Ansteuerung einer elektrischen Heizung für Fahrzeuge, die alternativ als elektrische Zusatzheizung oder aber auch als elektrische Hauptheizung für beispielsweise Hybrid- oder Elektrofahrzeuge eingesetzt werden kann. Ferner betrifft die Erfindung eine elektrische Heizung, insbesondere für ein Fahrzeug mit einer Ansteuervorrichtung.The invention relates to a device for controlling an electric heater for vehicles, which can be used alternatively as an electric booster heater or as the main electrical heating for example, hybrid or electric vehicles. Furthermore, the invention relates to an electric heater, in particular for a vehicle with a drive device.
Es ist bekannt, Fahrzeuge mit Verbrennungsmotoren neben einer vom Motorkühlmittel (Kühlwasser) betriebenen Heizung auch mit einer elektrischen Zusatzheizung zu versorgen. Diese elektrische Zusatzheizung weist im Allgemeinen mehrere Heizelemente in Form insbesondere von PTC-Elementen auf. Diese Heizelemente sind zumeist in Form mehrerer Heizstränge angeordnet, die einzeln wahlweise zu- bzw. abgeschaltet werden können, um die jeweils erforderliche Wärmemenge zur Verfügung zu stellen.It is known to provide vehicles with internal combustion engines in addition to a powered by the engine coolant (cooling water) heating with an additional electric heater. This electrical auxiliary heater generally has a plurality of heating elements in the form of in particular of PTC elements. These heating elements are usually arranged in the form of several heating strands, which can be selectively switched on or off individually to provide the required amount of heat available.
Die elektrische Ansteuerung derartiger elektrischer Heizungen erfolgt über eine elektrische Schaltung, die unter anderem ein zumeist als Transistor ausgeführtes elektrisches bzw. elektronisches Bauteil für die Einstellung des jeweils erforderlichen elektrischen Stroms umfasst. Im Betrieb heizt sich dieses Bauteil im Allgemeinen auf, weshalb es gekühlt werden muss. Es ist bekannt, derartige zu kühlende Bauteile bei einer Vorrichtung zur Ansteuerung einer elektrischen Heizung thermisch mit einem Kühlkörper zu koppeln. Die Montage der einzelnen Komponenten einer Vorrichtung der zuvor genannten Art kann mitunter recht aufwendig sein, was sich auf die Herstellungskosten auswirkt, indem diese erhöht sind.The electrical control of such electric heaters via an electrical circuit, which includes, inter alia, a running mostly as a transistor electrical or electronic component for adjusting the respective required electric current. In operation, this component heats up in general, so it must be cooled. It is known to thermally couple such components to be cooled in a device for controlling an electric heater with a heat sink. The assembly of the individual components of a device of the aforementioned type can sometimes be quite expensive, which has an effect on the manufacturing costs by these are increased.
Aufgabe der Erfindung ist es, eine Vorrichtung zur Ansteuerung einer elektrischen Heizung für Fahrzeuge zu schaffen, deren Montage, insbesondere was die elektrische Kontaktierung einer eine elektrische Schaltung aufweisenden Platine und die Aufrechterhaltung der thermischen Kopplung der zu kühlenden Bauteile mit einem Kühlkörper betrifft, vereinfacht ist.The object of the invention is to provide a device for controlling an electric heater for vehicles whose assembly, in particular as regards the electrical contacting of a circuit comprising an electrical circuit and the maintenance of the thermal coupling of the components to be cooled with a heat sink, is simplified.
Zur Lösung dieser Aufgabe wird mit der Erfindung (i) eine Vorrichtung zur Ansteuerung einer elektrischen Heizung für Fahrzeuge vorgeschlagen, die versehen ist mit den Merkmalen des Anspruchs 1, und (ii) eine elektrische Heizung nach Anspruch 7 vorgeschlagen. Einzelne Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.To solve this problem is proposed by the invention (i) a device for controlling an electric heater for vehicles, which is provided with the features of claim 1, and (ii) proposed an electric heater according to claim 7. Individual embodiments of the invention are the subject of the dependent claims.
Bei der erfindungsgemäßen Vorrichtung erfolgt die Kontaktierung der Platine, auf der sich verschiedene elektrische bzw. elektronische Bauteile einer elektrischen Schaltung befinden, durch Pressfit-Anschlussstifte. Diese Pressfit-Anschlussstifte sind an Leitern ausgebildet, die für die Weiterleitung elektrischer Signale oder aber auch der Betriebsspannung für die elektrische Heizung dienen. Die diesbezüglichen elektrischen Leiter sind erfindungsgemäß fest in dem Gehäuse montiert. Die Platine trägt unter anderem auch mindestens ein zu kühlendes Bauteil, wozu im Gehäuse ein Kühlkörper montiert bzw. von dem Gehäuse gehalten ist, der im Wesentlichen zwei Abschnitte aufweist, nämlich einen Wärmeaufnahmeabschnitt und einen Wärmeabführabschnitt. Der Wärmeaufnahmeabschnitt, der im Gehäuse angeordnet ist, weist eine in dem Gehäuse freiliegende Wärmekopplungsfläche auf, die zur thermischen Kopplung mit dem mindestens einen zu kühlenden Bauteil vorgesehen ist. Der Wärmeabführabschnitt dient zur Abführung der von dem Wärmeaufnahmeabschnitt aufgenommenen Wärme, und zwar an die Umgebung um den Wärmeabführabschnitt herum. Der Wärmeabführabschnitt des Kühlkörpers ist zweckmäßigerweise außerhalb des Gehäuses angeordnet, was aber nach der Erfindung nicht zwingend erforderlich ist.In the device according to the invention, the contacting of the board, on which various electrical or electronic components of an electrical circuit are located, by Pressfit pins. These pressfit pins are formed on conductors which serve for the transmission of electrical signals or else the operating voltage for the electric heater. The relevant electrical conductors according to the invention are firmly mounted in the housing. The board also carries, among other things, at least one component to be cooled, for which purpose a heat sink is mounted in the housing or held by the housing, which has essentially two sections, namely a heat-absorbing section and a heat-dissipating section. The heat receiving portion, which is arranged in the housing, has an exposed in the housing heat coupling surface, which is provided for thermal coupling with the at least one component to be cooled. The heat dissipation section serves to dissipate the heat received by the heat receiving portion to the environment around the heat dissipation portion. The heat dissipation section of the heat sink is expediently arranged outside the housing, but this is not absolutely necessary according to the invention.
Die Montage der erfindungsgemäßen Vorrichtung gestaltet sich als denkbar einfach. Die erforderlichen elektrischen Leiter (mit nach außen geführten Anschlusselementen für die elektrische Heizung bzw. für am Gehäuse anbringbare elektrische Stecker o. dgl.) und der Kühlkörper werden zunächst in dem Gehäuse montiert, wobei hierzu das Gehäuse beispielsweise auch spritzgusstechnisch um diese Elemente herum geformt sein kann. In jedem Fall bilden nach diesem Montagevorgang Gehäuse, Kühlkörper und die elektrischen Leiter eine Baugruppe. Innerhalb des Gehäuses existiert dabei ein Platinenaufnahmebereich, in dem die Wärmekopplungsfläche des Kühlkörpers freiliegt. Neben der Wärmekopplungsfläche erstrecken sich die Pressfit-Anschlussstifte, und zwar in einer zur Flächennormale der Wärmekopplungsfläche im Wesentlichen parallelen Richtung. Auf die Pressfit-Anschlussstifte wird nun die Platine gesteckt, so dass die Pressfit-Anschlussstifte von den Durchkontaktierungsaufnahmebohrungen der Platine mechanisch kraftschlüssig und elektrisch kontaktiert aufgenommen sind. Die Pressfit-Anschlussstifte weisen dabei eine doppelte Funktion auf, nämlich zum einen dienen sie der elektrischen Kontaktierung der Platine und zum anderen der Aufrechterhaltung der thermischen Kopplung des mindestens einen zu kühlenden Bauteils mit der Wärmekopplungsfläche des Wärmeaufnahmeabschnitts des Kühlkörpers, wenn sich die Platine in ihrer Einbau- und Fixierlage innerhalb des Gehäuses befindet. Der Platinenaufnahmebereich kann anschließend durch einen Gehäusedeckel o. dgl. verschlossen werden.The assembly of the device according to the invention is as simple as possible. The required electrical conductors (with outwardly directed connection elements for the electric heater or attachable to the housing electrical plug o. The like.) And the heat sink are first mounted in the housing, for this purpose, the housing, for example, injection molded around these elements around can. In any case, form after this assembly process housing, heatsink and the electrical conductors an assembly. Within the housing there is a board receiving area in which the heat coupling surface of the heat sink is exposed. In addition to the heat coupling surface, the pressfit pins extend, in a direction substantially parallel to the surface normal of the heat coupling surface. The printed circuit board is now plugged onto the pressfit pins, so that the pressfit pins are received mechanically frictionally and electrically contacted by the through-hole receiving holes of the board. The Pressfit pins have a dual function, namely on the one hand they serve the electrical contacting of the board and on the other hand, the maintenance of the thermal coupling of the at least one component to be cooled with the heat coupling surface of the heat receiving portion of the heat sink, when the board in their installation - and fixing position is located within the housing. The board receiving area can subsequently be closed by a housing cover or the like.
Nach dem erfindungsgemäßen Vorschlag sind also keinerlei Halte- bzw. Klemmelemente o. dgl. zur Fixierung der Platine am Gehäuse und damit relativ zum Kühlkörper und insbesondere zu dessen Wärmekopplungsfläche erforderlich. Vielmehr werden diese separaten mechanischen Fixierungselemente durch die für die elektrische Kontaktierung erforderlichen Anschlussstifte ersetzt, die zu diesem Zweck als Pressfit-Anschlussstifte ausgeführt sind. Unter Pressfit-Anschlussstift im Sinne dieser Erfindung wird jede Art und Ausgestaltung von elektrischen Anschlussstiften verstanden, die, ohne verlötet und damit stoffschlüssig mit der Platine verbunden zu sein, eine kraftschlüssige Verbindung mit der Platine eingehen. Hierbei können die Pressfit-Anschlussstifte innerhalb ihres in einer Durchkontaktierungsaufnahmebohrung aufgenommenen Abschnitts starr bzw. massiv oder aber flexible bzw. elastisch (z. B. durch Ausbildung eines nadelöhrähnlichen Lochs) ausgeführt sein.According to the proposal of the invention, therefore, no holding or clamping elements o. The like. For fixing the board on the housing and thus relative to the heat sink and in particular to its Heat coupling surface required. Rather, these separate mechanical fixing elements are replaced by the pins required for electrical contacting, which are designed for this purpose as Pressfit pins. Under Pressfit pin in the sense of this invention is understood to be any type and configuration of electrical pins that, without being soldered and thus to be materially connected to the board, enter into a frictional connection with the board. In this case, the pressfit connection pins can be made rigid or solid or flexible (eg by forming a needle-like hole) within their section accommodated in a through-hole receiving bore.
In weiterer vorteilhafter Ausgestaltung der Erfindung kann vorgesehen sein, dass in dem Gehäuse weitere Pressfit-Anschlussstifte für die Zuleitung und/oder den Abgriff von elektrischen Signalen an bzw. von der elektrischen Schaltung angeordnet sind, die wie die Pressfit-Anschlussstifte der Betriebsspannungsversorgungsleiter angeordnet sowie ausgerichtet und von weiteren Durchkontaktierungsaufnahmebohrungen der Platine aufgenommen sind.In a further advantageous embodiment of the invention it can be provided that in the housing further Pressfit pins are arranged for the supply and / or tapping of electrical signals to or from the electrical circuit, which arranged as the Pressfit pins of the operating voltage supply conductor and aligned and are received by further Durchkontaktierungsaufnahmebohrungen the board.
Die thermische Kopplung des zu kühlenden Bauteils mit der Wärmekopplungsfläche des Kühlkörpers kann entweder direkt oder indirekt erfolgen. Beispielsweise ist es möglich, dass das zu kühlende Bauteil in der Einbau- und Fixierlage der Platine der Wärmekopplungsfläche des Wärmeaufnahmeabschnitts des Kühlkörpers zugewandt ist. Alternativ dazu kann aber auch vorgesehen sein, dass das zu kühlende Bauteil auf der Oberseite der Platine angeordnet ist, dass unterhalb des zu kühlenden Bauteils in der Platine mindestens eine Wärmekopplungselement zur thermischen Kopplung der Oberseite der Platine mit deren Unterseite angeordnet ist und dass die Unterseite der Platine in deren Einbau- und Fixierlage der Wärmekopplungsfläche des Wärmeaufnahmeabschnitts des Kühlkörpers zugewandt ist. In beiden Fällen kann das zu kühlende Bauteil bzw. die Unterseite der Platine die Wärmekopplungsfläche des Wärmeaufnahmeabschnitts des Kühlkörpers kontaktiert oder mit der Wärmekopplungsfläche über ein Wärmeleitmaterial, wie z. B. eine Wärmeleitfolie oder -paste, in thermisch weiter verbesserter Weise gekoppelt sein.The thermal coupling of the component to be cooled with the heat coupling surface of the heat sink can be done either directly or indirectly. For example, it is possible that the component to be cooled in the installation and fixing position of the board faces the heat coupling surface of the heat receiving portion of the heat sink. Alternatively, however, it can also be provided that the component to be cooled is arranged on the upper side of the board, that below the component to be cooled in the board at least one heat coupling element for thermal coupling of the upper side of the board is arranged with its underside and that the underside of the Board facing in the installation and fixing of the heat coupling surface of the heat receiving portion of the heat sink. In both cases, the component to be cooled or the underside of the board contacted the heat coupling surface of the heat receiving portion of the heat sink or with the heat coupling surface via a Wärmeleitmaterial such. As a Wärmeleitfolie or paste, be coupled in a thermally further improved manner.
