Description

Beschreibungdescription
Kühlvorrichtung für ein Kraftfahrzeug mit einem Kühlkanal für ein KühlmediumCooling device for a motor vehicle with a cooling channel for a cooling medium
Die Erfindung bezieht sich auf eine Kühlvorrichtung für ein Kraftfahrzeug mit einem Kühlkanal für ein Kühlmedium. Kühlvorrichtungen für Kraftfahrzeuge sind bekannt. In der Regel handelt es sich dabei um einen Wasserkühler, bei dem das Wasser durch ein Kanalsystem geleitet wird, was durch Flüssigkeitspumpen erzielt wird. Solche Kühlvorrichtungen dienen allgemein der Kühlung des Motors.The invention relates to a cooling device for a motor vehicle with a cooling channel for a cooling medium. Cooling devices for motor vehicles are known. As a rule, this is a water cooler, in which the water is conducted through a sewer system, which is achieved by liquid pumps. Such cooling devices are generally used to cool the engine.
Der Erfindung liegt die Aufgabe zugrunde, eine Kühlvorrichtung für ein Kraftfahrzeug zu schaffen, die neben der Funktion der Kühlung des Motors noch eine weitere erfüllt .The object of the invention is to create a cooling device for a motor vehicle which, in addition to the function of cooling the motor, also fulfills another.
Die der Erfindung zugrundeliegende Aufgabe wird durch eine Kühlvorrichtung gelöst, bei der elektronische Bauteile an der Außenseite des Kühlkanals angeordnet sind. Als elektronische Bauteile können beispielsweise Kondensatoren, Prozessoren oder Transistoren eingesetzt werden. Sie dienen in der Regel der elektronischen Steuerung oder Regelung von Vorgängen im Kraftfahrzeug. Unter der Außenseite des Kühlkanals sind die Außenseiten des Spiralgehäuses oder der Schläuche oder der Ventile zu verstehen, die in den Kühlkreislauf eingebaut sind. Die Anordnung der elektronischen Bauteile an der Außenseite des Kühlkanals kann beispielsweise durch Klemmen oder durch Verschrauben erfolgen. Es hat sich in überraschender Weise gezeigt, dass sich mit der Kühlvorrichtung für ein Kraftfahrzeug auch elektronische Bauteile derart kühlen lassen, so dass die hohen Temperaturen, denen sie normalerweise direkt ausgesetzt sind, keine nachteiligen Beschädigungen hervorrufen können. Dadurch ist es möglich, elektronische Bauteile einzusetzen, die temperaturempfindlicher und damit preiswerter sind. Die Kühlwirkung erfolgt dabei durch die Anordnung der elektronischen Bauteile in der Nähe des Kühlmediums, wobei als Kühlmedium in der Regel Wasser dient.The object on which the invention is based is achieved by a cooling device in which electronic components are arranged on the outside of the cooling channel. Capacitors, processors or transistors, for example, can be used as electronic components. They are usually used to electronically control or regulate processes in the motor vehicle. The outside of the cooling channel is understood to mean the outside of the volute casing or the hoses or the valves which are built into the cooling circuit. The electronic components can be arranged on the outside of the cooling duct by clamping or screwing, for example. Surprisingly, it has been shown that the cooling device for a motor vehicle can also cool electronic components in such a way that the high temperatures to which they are normally directly exposed cannot cause any disadvantageous damage. This makes it possible to use electronic components that are more temperature-sensitive and therefore cheaper. The The cooling effect takes place through the arrangement of the electronic components in the vicinity of the cooling medium, water generally serving as the cooling medium.
