  • Energy conversion device, notably for a system for electrically driving an underwater compression and pumping station
    Patent number: 9185827
    Abstract: The energy conversion device (10) includes a power module (14), elements (16) for cooling the power module (14), and a sealed enclosure (12) for housing the power module (14) and at least one portion of the cooling elements (16). The cooling elements (16) include a cooling circuit 18, in which a heat transfer fluid circulates, a first heat exchange (20) with the power module (14), through which passes the heat transfer fluid of the cooling circuit (18) and at least one pump (24) for driving the heat transfer fluid circulating in the circuit (18). The enclosure (12) includes an area (26) for receiving heat transfer fluid, filled with heat transfer fluid, and the cooling circuit (18) includes an inlet orifice (28) in the circuit (18) made upstream from the driving pump (24) and opening into the heat transfer fluid of the receiving area (26).
