Abstract
Die Erfindung betrifft eine Anordnung mit einem Gehäuse (1) und einer darin auf einem Gehäuseboden (2) angeordneten Leistungselektronikschaltung (5, 6, 7), wobei zumindest in dem Gehäuseboden (2) ein Hohlraum mit zum Gehäuseäußeren führenden Anschlüssen (9, 10) zum Zu- und Abführen einer Kühlflüssigkeit ausgebildet ist, wobei auf der dem Hohlraum abgewandten Seite des Gehäusebodens (2) Kühlschlangen (11) ausgebildet sind, die von der Kühlflüssigkeit durchströmt werden können, und wobei in dem Gehäuse (1) ein durch einen Elektromotor (14) angetriebener Ventilator (12; 13) derart angeordnet ist, dass dessen Luftstrom durch die Kühlschlangen (11) gekühlt wird und anschließend die Leistungselektronikschaltung (5, 6,7) entwärmt. The invention relates to an arrangement having a housing (1) and a power electronics circuit (5, 6, 7) arranged therein on a housing bottom (2), wherein at least in the housing bottom (2) has a cavity with connections (9, 10) leading to the housing exterior. for the supply and removal of a cooling liquid is formed, wherein on the side facing away from the cavity of the housing bottom (2) cooling coils (11) are formed, which can be flowed through by the cooling liquid, and wherein in the housing (1) by an electric motor ( 14) driven fan (12; 13) is arranged such that its air flow through the cooling coils (11) is cooled and then the power electronics circuit (5, 6,7) is cooled.

Der erste Kühlkörper ist dabei angeordnet, um Wärme mit mindestens einem Element des Wechselrichters auszutauschen und die zweite Wärmesenke ist angeordnet, um Wärme mit der ersten Wärmesenke auszutauschen.The first heat sink is arranged to exchange heat with at least one element of the inverter and the second heat sink is arranged to exchange heat with the first heat sink.

Es ist daher die Aufgabe der Erfindung, eine Anordnung mit einem Gehäuse und einer darin auf einem Gehäuseboden angeordneten Leistungselektronikschaltung anzugeben, die auf einfachere und flexible Weise eine effektive Kühlung der Leistungselektronikschaltung bewirkt.It is therefore the object of the invention to provide an arrangement with a housing and a power electronics circuit arranged therein on a housing bottom, which effects effective cooling of the power electronics circuit in a simpler and more flexible manner.
Die Aufgabe wird durch eine Anordnung gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.The object is achieved by an arrangement according to claim 1. Advantageous developments are specified in the subclaims.
Demnach ist bei einer Anordnung mit einem Gehäuse und einer darin auf einem Gehäuseboden angeordneten Leistungselektronikschaltung zumindest in dem Gehäuseboden ein Hohlraum mit zum Gehäuseäußeren führenden Anschlüssen zum Zu- und Abführen einer Kühlflüssigkeit ausgebildet, wobei auf der dem Hohlraum abgewandten Seite des Gehäusebodens Kühlschlangen ausgebildet sind, und wobei in dem Gehäuse ein durch einen Elektromotor angetriebener Ventilator derart angeordnet ist, dass dessen Luftstrom durch die Kühlschlangen gekühlt wird und anschließend die Leistungselektronikschaltung entwärmt. Accordingly, in the case of an arrangement having a housing and a power electronics circuit arranged therein on a housing bottom, a cavity is formed at least in the housing bottom with leads leading to the housing for supplying and discharging a cooling liquid, cooling coils being formed on the side of the housing bottom facing away from the cavity, and wherein in the housing a fan driven by an electric motor is arranged such that its air flow is cooled by the cooling coils and then the power electronics circuit is cooled.
Die Leistungselektronikschaltung ist also auf dem Gehäuseboden angeordnet, der als Kälteverteiler fungiert und damit nicht nur die Kühlschlangen sondern auch die auf ihm angeordneten Bauteile der Leistungselektronikschaltung direkt kühlt. Die Kühlschlangen stehen mit dem Hohlraum in Verbindung und werden von dem Kühlmittel durchflossen, so dass sie besser gekühlt sind als lediglich durch Wärmeübertragung gekühlte Kühlrippen. Zusätzlich sorgt ein Ventilator für eine Luftzirkulation durch die Kühlschlangen und zu der Leistungselektronikschaltung. Der Ventilator wird dabei durch einen Elektromotor angetrieben und ist daher unabhängig von einem Kühlmittelfluss.The power electronics circuit is thus arranged on the housing bottom, which acts as a cooling manifold and thus not only the cooling coils but also the components of the power electronics circuit arranged on it directly cools. The cooling coils are connected to the cavity and are flowed through by the coolant, so that they are better cooled than just heat transfer cooled cooling fins. In addition, a fan provides air circulation through the cooling coils and power electronics circuitry. The fan is driven by an electric motor and is therefore independent of a coolant flow.
In einer ersten Variante der erfindungsgemäßen Anordnung ist der Elektromotor in dem Gehäuse angeordnet. Hierdurch ist keine Durchführung der Antriebswelle durch eine Gehäusewand erforderlich.In a first variant of the arrangement according to the invention, the electric motor is arranged in the housing. As a result, no implementation of the drive shaft through a housing wall is required.
In einer zweiten Variante der erfindungsgemäßen Anordnung ist der Elektromotor außerhalb des Gehäuses angeordnet, wodurch ein Austausch des Elektromotors möglich ist, ohne das Gehäuse öffnen zu müssen.In a second variant of the arrangement according to the invention, the electric motor is arranged outside the housing, whereby an exchange of the electric motor is possible without having to open the housing.
Hierbei kann der Elektromotor in vorteilhafter Weise an einer Gehäusewand angeordnet sein.In this case, the electric motor can advantageously be arranged on a housing wall.
