Abstract
(EN)
A box-shaped inner case (3) is accommodated in a box-shaped outer case (2) with a gap therebetween forming refrigerant flow passageways (27) on five faces other than opening faces (14, 24). A frame-shaped cover (6) spans across an opening edge of the outer case (2) and an opening edge of the inner case (3). With a capacitor element (4) comprising a film capacitor disposed in the inner case (3), a potting material (5) having thermal conductivity is filled so that the capacitor element (4) is buried leaving terminals (4a, 4b). Cooling water flows along the longitudinal direction of the outer case (2) using one refrigerant pipe connector (15) as a refrigerant entry and another as a refrigerant exit.
(FR)
L'invention concerne un boîtier interne en forme de boîte (3) qui est logé dans un boîtier externe en forme de boîte (2) avec un espace entre ceux-ci formant des passages d'écoulement de fluide frigorigène (27) sur cinq faces autres que des faces d'ouverture (14, 24). Un couvercle en forme de cadre (6) s'étend à travers un bord d'ouverture du boîtier externe (2) et un bord d'ouverture du boîtier interne (3). Avec un élément de condensateur (4) comprenant un condensateur de film disposé dans le boîtier interne (3), un matériau d'enrobage (5) ayant une conductivité thermique est rempli de telle sorte que l'élément de condensateur (4) est enfoui, laissant des bornes (4a, 4b). L'eau de refroidissement s'écoule le long de la direction longitudinale du boîtier externe (2) à l'aide d'un raccord de tuyau de fluide frigorigène (15) en tant qu'entrée de fluide frigorigène et autre comme sortie de fluide frigorigène.
