Abstract: Provided is a deionized-water cooling system having a main circuit for cooling electrical equipment. The system includes a deionizer circuit including (i) a deionizer for producing deionized water and (ii) a throttle and a main pumping system configured for circulating (i) the deionized water within the main circuit at a first flow rate and (ii) the water flow within the deionizer at a second flow rate. The circulating occurring when the electrical equipment is operating. The electrical equipment is configured for receiving power from a primary power source. Also included is a secondary pumping system configured for (i) receiving power from a secondary power source, (ii) circulating the deionized water within the main circuit, and (iii) circulating the water flow within the deionizer at the second flow rate via the throttle when the electrical equipment is inoperable.

Abstract: The energy conversion device (10) includes a power module (14), a unit (16) for cooling the power module (14), and a sealed enclosure (12) housing the power module (14) and at least part of the cooling unit (16). The cooling unit (16) includes a cooling circuit (18), in which a coolant circulates, a first heat exchanger (20) with the power module (14), through which the coolant passes, and at least one pump (24) making the coolant circulate in the circuit (18). The cooling circuit (18) includes a pressure regulating branch (26), extending between an outlet and an inlet of the driving pump (24), the regulating branch (26) including a pressure regulating valve (28), normally closed, capable of opening when the pressure difference between the outlet and the inlet of the driving pump (24) exceeds a predetermined threshold.

Abstract: The electric module includes a sealed enclosure (104), at least one item of electrical equipment (106) arranged in the sealed enclosure (104) and which, in operation, heats the atmosphere, and a secondary cooling circuit. The secondary circuit includes a guiding channel (108) arranged in the sealed enclosure (104) so as to guide the atmosphere which has been heated by the item or items of electrical equipment (106) towards its top opening (108B), and a passage (109) for the atmosphere delimited, at least partly, by the sealed enclosure (104) in order to enable a cooling of the atmosphere upon contact with the sealed enclosure (104). The guiding channel (108) is thermally isolated from the sealed enclosure (104).
