Abstract:
1. A method of cooling a static electronic power converter device comprising at least one electrical circuit comprising an assembly of active components and of passive components interconnected in a manner suitable for performing a determined electrical energy conversion function, said circuit including means for inputting electricity that is to be converted and means for outputting converted electricity and being mounted in a closed leaktight radiator housing with only an inlet and outlet means for inputting electricity and for outputting converted electricity of said circuit communicating between the inside of the housing and the outside, the method being characterized in that the distribution of heat energy given off by said active and passive components is made uniform throughout the inside volume of said housing, and said heat energy is transferred from said radiator housing by forced convection in substantially uniform manner over the entire inside surface of the walls of said housing, by causing at least one fluid contained inside said leaktight housing to circulate in a closed circuit including partition means inside said housing, said circulation of fluid inside said housing being accelerated with at least two propulsion means, said partition means of said housing being positioned at least between said propulsion means.
