MONITORED SPRAY NOZZLE COOLING DEVICE FOR ELECTRICAL EQUIPMENT CONNECTED TO A FLUID CIRCUIT

Abstract

A cooling device (DR) is fitted to a piece of equipment (E1) comprising a sealed enclosure (BE) containing N electrical elements (EE1-EE3), an inlet (EB) through which a first section (P1) of a fluidic circuit (CF) flows, and an outlet (SB) connected to a second section (P2) of the fluidic circuit (CF). This device (DR) includes spray nozzles (BA1-BA3) connected in the enclosure (BE) to the first section (P1) by being installed above the electrical elements (EE1-EE3) to spray them, a valve (VC) installed in the second section (P2), and a control module (MC) arranged to place the valve (VC) in a state at least partially closed, such as to cause a selected increase in the volume of dielectric fluid in the enclosure (BE) in the presence of at least one abnormal measurement of at least one parameter representative of a cooling level of at least one of the electrical elements (EE1-EE3).
