Abstract

L'invention concerne un dispositif de pompe. Ce dispositif de pompe est équipé : d'une pompe (2) ; d'un moteur électrique (3) ; d'une unité de commande (10) contenant une partie commande (20) ; d'un ventilateur (28) refroidissant l'unité de commande (10) ; d'un premier capteur de température (24) qui mesure la température à l'intérieur de l'unité de commande (10) ; et d'un seconde capteur de température (26) qui mesure la température d'un élément de puissance (22a) d'un onduleur (22). La partie commande (20) démarre le ventilateur (28) lorsque la température à l'intérieur de l'unité de commande (10) est supérieure à une première valeur seuil, ou lorsque la température de l'élément de puissance (22a) est supérieure à une seconde valeur seuil, et arrête le ventilateur (28) lorsque la température de l'élément de puissance (22a) est inférieure à une troisième valeur seuil, ou lorsque la température à l'intérieur de l'unité de commande (10) est inférieure à une quatrième valeur seuil.
