Description

Technisches GebietTechnical area

Die Erfindung betrifft eine elektrische Heizvorrichtung gemäß dem Oberbegriff von Anspruch 1. Darüber hinaus betrifft die Erfindung eine Heiz- oder Klimaanlage mit einer solchen Heizvorrichtung.The invention relates to an electric heater according to the preamble of claim 1. Furthermore, the invention relates to a heating or air conditioning system with such a heater.

Stand der TechnikState of the art

Für die Beheizung des Fahrzeuginnenraums eines Kraftfahrzeugs wird üblicherweise die Abwärme des Kraftfahrzeugmotors verwendet. Diese Abwärme entsteht, nachdem der Kraftfahrzeugmotor eingeschaltet ist. In einem für die gewünschte Heizleistung ausreichenden Maß kann die Abwärme in der Regel jedoch erst nach einer gewissen Warmlaufzeit bereitgestellt werden. Hinzu kommt, dass bei neueren, verbrauchsärmeren Kraftfahrzeugmotoren ein vergleichsweise geringes Maß an Abwärme entsteht. Bei Kraftfahrzeugen mit einem Elektromotor als Antriebsmotor fällt diese Wärmequelle vollständig weg bzw. ist erheblich reduziert, weil der Elektromotor im Vergleich zu einem Verbrennungsmotor kaum Abwärme erzeugt. Daher ist es üblich, vor allem bei kalten Witterungsbedingungen, elektrische Heizvorrichtungen bzw. elektrische Zusatzheizvorrichtungen einzusetzen.For the heating of the vehicle interior of a motor vehicle, the waste heat of the motor vehicle engine is usually used. This waste heat arises after the vehicle engine is turned on. In a sufficient amount for the desired heat output, however, the waste heat can usually be provided only after a certain warm-up time. In addition, in modern, low-consumption motor vehicle engines, a comparatively small amount of waste heat is created. In motor vehicles with an electric motor as a drive motor, this heat source completely falls away or is considerably reduced, because the electric motor hardly generates waste heat in comparison to an internal combustion engine. It is therefore customary, especially in cold weather conditions, to use electric heaters or additional electric heaters.

EP 0 901 311 A2 offenbart diesbezüglich eine elektrische Heizvorrichtung für Kraftfahrzeuge mit mehreren blockartig zusammengesetzten Heizelementen. Dabei werden die einzelnen Heizelemente durch einen Rahmen zusammengehalten. In den Rahmen ist auch eine Steuereinheit zur elektronischen Regelung der Heizleistung integriert, so dass die Heizelemente und die Steuereinheit eine gemeinsame Baueinheit bilden. Dabei sind für die Kühlung der Steuereinheit Kühlkörper vorgesehen, die in den zu erwärmenden Luftstrom ragen. Dadurch werden zusätzliche Bauelemente eingesetzt, um die Steuereinheit kühlen zu können, was die Kosten erhöht und die Montage verkompliziert. EP 0 901 311 A2 discloses in this regard an electric heating device for motor vehicles with a plurality of block-like composite heating elements. The individual heating elements are held together by a frame. In the frame, a control unit for electronic control of the heating power is integrated, so that the heating elements and the control unit form a common structural unit. In this case, heat sinks are provided for the cooling of the control unit, which protrude into the air stream to be heated. As a result, additional components are used to cool the control unit, which increases the cost and complicates the assembly.

Eine Heizvorrichtung der im Oberbegriff des Patentanspruchs 1 beschriebenen Art ist aus der EP 2 863 143 A1 bekannt.A heater of the type described in the preamble of claim 1 is known from EP 2 863 143 A1 known.

Eine solche Bauform, bei der ein Leiterplattenabschnitt und/oder auf einem Leiterplattenabschnitt und/oder benachbart zu einem Leiterplattenabschnitt angeordnete Steckvorrichtungen aus dem Gehäuse herausragen, erlaubt eine energiesparende Kühlung elektrischer Komponenten. Außerdem entfallen aufwendige Verkabelungen, die andernfalls weiteres Material sowie zusätzlichen Bauraum beanspruchen.An embodiment of the invention relates to an electrical heating device, in particular for a motor vehicle, comprising at least one heating element and at least one control device having a housing, with at least one printed circuit board, with a first printed circuit board section and a second printed circuit board section, and with at least one first plug-in device and with at least one second plug-in device, wherein the two plug-in devices serve for connecting the at least one heating element to the control device.

In addition, expensive cabling, which otherwise require further material and additional space omitted.

In einem weiteren Ausführungsbeispiel der elektrischen Heizvorrichtung sind die zumindest eine erste Steckvorrichtung und die zumindest eine zweite Steckvorrichtung komplementär zueinander ausgebildet und/oder lösbar miteinander verbindbar.In a further exemplary embodiment of the electrical heating device, the at least one first plug-in device and the at least one second plug-in device are designed to be complementary to one another and / or detachably connectable to one another.

Eine zusätzliche Ausführungsform der elektrischen Heizvorrichtung sieht vor, dass die zumindest eine erste Steckvorrichtung mit dem zweiten Leiterplattenabschnitt verlötet oder vercrimpt ist. Dies ermöglicht eine einfache und unkomplizierte Verbindung wichtiger Komponenten der elektrischen Heizvorrichtung, woraus sich Vorteile für die Montage und die Wartung der elektrischen Heizvorrichtung ergeben.An additional embodiment of the electric heating device provides that the at least one first plug-in device is soldered or crimped to the second printed circuit board section. This allows a simple and uncomplicated connection of important components of the electric heater, resulting in advantages for the installation and maintenance of the electric heater.

In einem weiteren Ausführungsbeispiel der elektrischen Heizvorrichtung weist der erste Leiterplattenabschnitt einen Teil auf, welcher im Wesentlichen wasserdicht abgeschlossen ist. Dadurch sind besonders wasserempfindliche Komponenten der elektrischen Heizvorrichtung vor Wasser geschützt. In vorteilhafter Weise wird damit die Lebensdauer der elektrischen Heizvorrichtung verlängert und ihre Störungsanfälligkeit deutlich reduziert.In a further exemplary embodiment of the electrical heating device, the first printed circuit board section has a part which is essentially watertight. As a result, particularly water-sensitive components of the electric heater are protected from water. In Advantageously, thus extending the life of the electric heater and their susceptibility to interference significantly reduced.

In einem zusätzlichen Ausführungsbeispiel der elektrischen Heizvorrichtung weist das zumindest eine Heizelement eine Anzahl von Positive-Temperature-Coefficient-Elementen auf. Diese auch als PTC-Elemente bezeichneten Komponenten der elektrischen Heizvorrichtung gewährleisten, dass sich im Fahrzeuginnenraum rasch eine für Fahrzeuginsassen komfortable Temperatur einstellt und insbesondere die Windschutzscheibe frei von Feuchtigkeitsbeschlag ist.In an additional embodiment of the electrical heating device, the at least one heating element has a number of positive-temperature-coefficient elements. These components of the electric heating device, also referred to as PTC elements, ensure that a comfortable temperature for vehicle occupants is quickly established in the vehicle interior and, in particular, the windscreen is free from moisture fogging.

Bei einer weiteren Ausführungsform der elektrischen Heizvorrichtung ist das zumindest eine Heizelement im Wesentlichen blockartig ausgebildet und weist eine Anzahl von durchgehenden, parallel zueinander angeordneten Öffnungen als Luftkanäle auf. Die Öffnungen erlauben in vorteilhafter Weise die Förderung eines Luftstroms durch das Heizelement. Dabei erwärmt sich der Luftstrom und erzeugt, sobald er in den Fahrzeuginnenraum geleitet wird, rasch die dort von den Fahrzeuginsassen gewünschte Raumtemperatur.In a further embodiment of the electric heating device, the at least one heating element is formed substantially block-like and has a number of continuous, mutually parallel openings as air channels. The openings advantageously allow the promotion of an air flow through the heating element.

Ein besonders vorteilhaftes Ausführungsbeispiel der elektrischen Heizvorrichtung sieht vor, dass das zumindest eine Heizelement zumindest eine wärmeableitende Oberfläche aufweist, mit einer Anzahl von Wärmeleitrippen, welche die zumindest eine wärmeableitende Oberfläche vergrößern. Durch die oberflächenvergrößernde Wirkung der Wärmeleitrippen wird die Wärmeübertragung von dem zumindest einen Heizelement auf den durch die am Heizelement angeordneten Öffnungen geförderten Luftstrom noch erheblich verbessert.A particularly advantageous embodiment of the electric heating device provides that the at least one heating element has at least one heat-dissipating surface, with a number of heat-conducting fins, which increase the at least one heat-dissipating surface. Due to the surface-enlarging effect of the heat-conducting ribs, the heat transfer from the at least one heating element to the air flow conveyed through the openings arranged on the heating element is still considerably improved.

In einem weiteren Ausführungsbeispiel der elektrischen Heizvorrichtung weist die zumindest eine Steuervorrichtung im Bereich der Leiterplatte zumindest einen Anschluss für eine Stromversorgung und/oder zumindest einen Anschluss für eine Ansteuerlogik auf.
