Abstract

Le dispositif électrique à refroidissement par boîte à eau comporte : - un corps principal (302) de dissipateur de chaleur (114) dans lequel est ménagé un canal d’écoulement du liquide de refroidissement présentant des ouvertures supérieures ; et - deux modules électroniques de puissance (110, 112) fermant chacun au moins une des ouvertures supérieures afin d’être refroidis par le liquide de refroidissement, chaque module électronique de puissance présentant au moins une paire de bornes électriques (502, 504) conçues pour présenter une tension continue. Les modules électroniques de puissance (110, 112) sont disposés avec leurs paires de bornes électriques (502, 504) en vis-à-vis l’une de l’autre selon une direction dite transverse (T), et le canal d’écoulement (308) comporte au moins un tronçon dit longitudinal dans lequel le liquide de refroidissement est destiné à s’écouler dans une direction dite longitudinale (L), perpendiculaire à la direction transverse (T). Figure pour l’abrégé : Fig. 5The water box cooling electric device comprises: - a main body (302) of a heat sink (114) in which a coolant flow channel having upper openings is provided; and - two power electronics modules (110, 112) each closing at least one of the upper openings in order to be cooled by the cooling liquid, each power electronics module having at least one pair of electrical terminals (502, 504) designed to present a DC voltage. The power electronic modules (110, 112) are arranged with their pairs of electrical terminals (502, 504) facing each other in a so-called transverse direction (T), and the flow (308) comprises at least one so-called longitudinal section in which the coolant is intended to flow in a so-called longitudinal direction (L), perpendicular to the transverse direction (T).
