The invention relates to a method for cooling a static electronic power converter device (1), comprising at least one electronic circuit (3) with an assembly of active and passive electronic components (11, 12, 13) mounted in a closed radiator housing (2), of which only the input and output means for said circuit communicate with the exterior of said housing, whereby the calorific heat distribution emitted by the passive and active components is evenly distributed throughout the internal volume of said housing and the calorific heat is transferred to the radiator housing by forced convection in an essentially uniform manner over the entire internal surface of the walls of said housing, by means of a closed circulation of at least one fluid (15) contained within said sealed housing. The invention further relates to a static electronic power converter device for carrying out said method.
La présente invention concerne un procédé de refroidissement d'un dispositif de conversion statique d'électronique de puissance (1) comportant au moins un circuit électrique (3) comprenant un assemblage de composants actifs et de composants passifs (11, 12, 13) monté dans un boîtier (2) radiateur fermé duquel seuls lesdits moyens d'entrée et de sortie dudit circuit communiquent avec l'extérieur dudit boîtier, selon lequel on homogénéise la répartition de l'énergie calorifique dégagée par lesdits composants actifs et passifs dans tout le volume interne dudit boîtier et l'on transfère ladite énergie calorifique au dit boîtier radiateur par convection forcée de façon sensiblement uniforme sur toute la surface interne des parois dudit boîtier par circulation en circuit fermé d'au moins un fluide (15) contenu à l'intérieur dudit boîtier étanche. L'invention concerne également un dispositif de conversion statique d'électronique de puissance permettant la mise en AEuvre du procédé.
