Abstract

L'invention concerne un dispositif de pompe qui est équipé d'une unité pompe submersible. Ce dispositif de pompe est équipé de l'unité pompe submersible (1) et d'une unité à terre (5). L'unité à terre (5) est équipée : d'une unité de commande (10) possédant une ailette de dissipation de chaleur (25) ; d'une conduite de distribution d'eau (11) connectée à une conduite d'admission (4) ; et d'un ventilateur (28) s'opposant à l'ailette de dissipation de chaleur (25). L'unité de commande (10) est équipée : d'un onduleur (22) permettant un changement de vitesse du moteur électrique (3) ; d'une partie commande (20) qui commande le fonctionnement de l'onduleur (22) ; et d'un couvercle de protection (26) qui recouvre l'onduleur (22) et la partie commande (20). Le couvercle de protection (26) possède une pluralité d'orifices d'aération (26a), et le ventilateur (28) est disposé entre un de ces orifices d'aération (26a) et la conduite de distribution d'eau (11).
