Die Erfindung betrifft eine Vorrichtung (1) zum Kühlen zumindest einer elektrischen und/oder elektronischen Leistungskomponente, beispielsweise eines Umrichters (2) und/oder einer Elektromaschine (3), eines Fahrzeuges, insbesondere eines Elektro- oder Hybridfahrzeuges, welches zumindest eine Waschanlage (7) zur Reinigung zumindest einer Fahrzeugscheibe und/oder der Fahrzeugscheinwerfer aufweist. Um auf möglichst einfache und bauraumsparende Weise eine ausreichende Kühlung von elektrischen und/oder elektronischen Leistungskomponenten zu erreichen, ist vorgesehen, dass die Vorrichtung (1) einen mit der Waschanlage (7) strömungsverbindbaren, mit der Flüssigkeit der Waschanlage (7) gespeisten Kühlkreislauf (8) aufweist. The invention relates to a device (1) for cooling at least one electrical and/or electronic power component, for example, a converter (2) and/or an electrical machine (3), of a vehicle, particularly of an electric or hybrid vehicle that has at least one washer system (7) for cleaning at least one vehicle window and/or the vehicle headlights. In order to achieve a sufficient cooling of electrical and/or electronic power components in the simplest and a space-saving manner, the invention provides that the device (1) has a cooling circuit (8), which can be connected to the washer system (7) and which is supplied with the liquid of the washer system (7). L'invention concerne un dispositif (1) permettant de refroidir au moins un élément de puissance électrique et/ou électronique, par exemple un convertisseur (2) et/ou un moteur électrique (3), de véhicule, notamment de véhicule électrique ou hybride, qui comprend au moins une installation de lavage (7) pour nettoyer au moins une vitre du véhicule et/ou les phares du véhicule. L'invention vise à parvenir à un refroidissement suffisant d'éléments de puissance électriques et/ou électroniques, de la manière la plus simple et la plus économe possible en termes d'encombrement. A cet effet, il est prévu que ledit dispositif (1) comprenne un circuit de refroidissement (8) alimenté par le liquide de l'installation de lavage (7) et pouvant être relié en écoulement avec ladite installation de lavage.
