Abstract
Description
Die Erfindung betrifft ein elektrisches Haustechnik-Heizgerät zur Beheizung von Wasser, insbesondere Durchlauferhitzer, mit einem Halbleiterschalter zur Schaltung der Leistung wenigstens eines elektrischen Heizkörpers.The invention relates to an electrical domestic heating device for heating water, in particular water heater, with a semiconductor switch for switching the power of at least one electric radiator.
Die
Ausgehend vom Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein elektrisches Haustechnik-Heizgerät mit einer verbesserten Kühlung des Halbleiterschalters mit geringem Montageaufwand vorzusehen.Based on the prior art, the present invention seeks to provide an electrical home automation heater with improved cooling of the semiconductor switch with low installation costs.
Erfindungsgemäß ist die obige Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen gegeben.According to the invention the above object is achieved by the features of claim 1. Advantageous embodiments of the invention are given in the dependent claims.
Danach ist der Halbleiterschalter außen an einem Wasserführungskörper des Heizgerätes wärmeleitend angeordnet. Der Wasserführungskörper ist der Bereich des Heizgerätes, in dem Kaltwasser eingeleitet und erwärmt wird. Dabei ist ein Kühlkörper mit einer ersten Seite und einer zweiten Seite vorgesehen, der an der ersten Seite wenigstens teilweise an dem Halbleiterschalter anliegt. Das Wasser strömt den Kühlkörper zur Kühlung des Halbleiterschalters an der zweiten Seite wenigstens teilweise an. Der Kühlkörper ist somit mit dem Halbleiterschalter thermisch verbunden und nimmt die beim Betrieb des Halbleiterschalters entstehende Wärme auf. Durch den Umstand, dass das Wasser den Kühlkörper anströmt, ist auch das Wasser mit dem Kühlkörper thermisch verbunden, so dass der Kühlkörper die Wärme, die von den Halbleiterschalter auf den Kühlkörper übertragen wird, an das Wasser abgibt. Hierdurch ist somit eine Kühlung des Halbleiterschalters erreicht.Thereafter, the semiconductor switch is arranged outside of a heat-conducting body of the heater heat-conducting. The water guide body is the area of the heater in which cold water is introduced and heated. In this case, a heat sink with a first side and a second side is provided, which bears against the semiconductor switch at least partially on the first side. The water at least partially flows to the cooling body for cooling the semiconductor switch on the second side. The heat sink is thus thermally connected to the semiconductor switch and absorbs the heat generated during operation of the semiconductor switch. Due to the fact that the water flows against the heat sink, the water is thermally connected to the heat sink, so that the heat sink releases the heat that is transferred from the semiconductor switch to the heat sink to the water. As a result, a cooling of the semiconductor switch is thus achieved.
Vorzugsweise besteht der Kühlkörper aus einem wärmeleitenden Material, insbesondere aus Kupfer oder Messing.Preferably, the heat sink is made of a thermally conductive material, in particular copper or brass.
In einer bevorzugten Ausgestaltung der Erfindung überträgt der Druck des Wassers im Gerät eine Andruckkraft vom Kühlkörper auf den Halbleiterschalter. Das Wasser drückt somit gegen den Kühlkörper, der dadurch gegen den Halbleiterschalter gedrückt wird. Hierdurch ist erreicht, dass der Kühlkörper optimal am Halbleiterschalter anliegt. Zusätzliche Befestigungsmittel, die den Kühlkörper gegen den Halbleiterschalter drücken, sind dabei nicht erforderlich, da der Kühlkörper allein durch die durch das Wasser entstehende Andruckkraft gegen den Halbleiterschalter gedrückt wird. Hierdurch ist die thermische Verbindung zwischen Halbleiterschalter und Kühlkörper und damit die Wärmeübertragung vom Halbleiterschalter auf den Kühlkörper verbessert.In a preferred embodiment of the invention, the pressure of the water in the device transmits a pressure force from the heat sink to the semiconductor switch. The water thus presses against the heat sink, which is thereby pressed against the semiconductor switch. This ensures that the heat sink is applied optimally to the semiconductor switch. Additional fastening means which press the heat sink against the semiconductor switch are not required, since the heat sink is pressed against the semiconductor switch solely by the pressure force generated by the water. As a result, the thermal connection between the semiconductor switch and the heat sink and thus the heat transfer from the semiconductor switch is improved on the heat sink.
Vorzugsweise ist die Andruckkraft des Wassers durch den bei fließendem Wasser im Wasserführungskörper entstehenden Fließdruck erreicht. In einer weiteren Ausgestaltung der Erfindung ist die Andruckkraft durch den statischen Druck des Wassers (z. B. Netzdruck) erreicht, wenn kein Wasser fließt und das Wasser im Wasserführungskörper steht.Preferably, the pressing force of the water is achieved by the resulting in running water in the water guide body flow pressure. In a further embodiment of the invention, the pressure force is achieved by the static pressure of the water (eg, network pressure) when no water flows and the water is in the water guide body.
Gemäß einem Ausführungsbeispiel ist der Kühlkörper verschieblich geführt. Hierdurch ist erreicht, dass der Kühlkörper leicht beweglich ist und sich an die Lage des Halbleiterschalters anpasst. Toleranzen bei der Befestigung des Halbleiterschalters sowie des Kühlkörpers werden hierdurch ausgeglichen, so dass eine einfache Montage erreicht ist.According to one embodiment, the heat sink is guided displaceably. This ensures that the heat sink is easily movable and adapts to the position of the semiconductor switch. Tolerances in the attachment of the semiconductor switch and the heat sink are thereby compensated, so that a simple assembly is achieved.
Gemäß einem weiteren Ausführungsbeispiel liegt der Halbleiterschalter an einer Halteplatte an und mit der Halteplatte ist eine Endstellung des Halbleiterschalters festgelegt. Hierdurch ist eine einfache Montage des Halbleiterschalters ermöglicht. Zudem erzeugt die Halteplatte einen Gegendruck, wenn der Kühlkörper gegen den Halbleiterschalter drückt, so dass der Kühlkörper optimal an dem Halbleiterschalter anliegt.According to a further embodiment, the semiconductor switch rests against a holding plate and with the holding plate an end position of the semiconductor switch is fixed. This allows a simple mounting of the semiconductor switch. In addition, the holding plate generates a back pressure when the heat sink presses against the semiconductor switch, so that the heat sink is applied optimally to the semiconductor switch.
Vorzugsweise ist im Bereich des Kühlkörpers eine Dichtung angeordnet, die dazu geeignet ist, den Wasserführungskörper nach außen abzudichten. Somit ist erreicht, dass kein Wasser aus dem Wasserführungskörper nach außen gelangt und insbesondere kein Wasser den Halbleiterschalter benetzt.Preferably, a seal is arranged in the region of the heat sink, which is suitable for sealing the water guide body to the outside. Thus, it is achieved that no water from the water guide body passes to the outside and in particular no water wets the semiconductor switch.
In einer bevorzugten Ausgestaltung der Erfindung ist die Dichtung als O-Ring-Dichtung ausgeführt und in eine Bohrung des Wasserführungskörpers eingelegt, wodurch eine einfache Montage und eine gute Dichtigkeit erreicht ist, auch wenn sich der Kühlkörper durch die Andruckkraft leicht bewegt.In a preferred embodiment of the invention, the seal is designed as an O-ring seal and inserted into a bore of the water guide body, whereby a simple assembly and a good seal is achieved, even if the heat sink moves easily by the pressing force.
Gemäß einem Ausführungsbeispiel ist in dem Wasserführungskörper eine Heizwendel angeordnet.According to one embodiment, a heating coil is arranged in the water guide body.
