CAPACITORS PACK FOR MOTOR VEHICLE POWER ELECTRONIC MODUL AND ITS CORRESPONDING MANUFACTURING METHOD

摘要

A capacitor block comprising electrochemical capacitors (11) housed in a metal vessel (9) provided with cooling fins (2). The vessel is filled with a thermally conductive and electrically insulating material (21). The capacitors are arranged by means of a bus bar (15) with positive polarity and a bus bar (16) with negative polarity kept separated by an insulating support (10). The positive bus bar comprises first holes (17) receiving positive pins (12) of the electrochemical capacitors (11) and the negative bus bar comprises second holes (18) receiving negative pins (13) of the electrochemical capacitors. The positive bus bar also comprises first release holes (19) allowing the negative pins to pass through the positive bus bar without making electrical contact and the negative bus bar also comprises second release holes (20) allowing the positive pins to pass through the negative bus bar without making electrical contact. According to the invention, the vessel comprises sealing means (10, 24) and degassing means (25).
