Title
(DE) LEISTUNGSMODUL MIT MINDESTENS DREI LEISTUNGSEINHEITEN
(EN) POWER MODULE HAVING AT LEAST THREE POWER UNITS
(FR) MODULE DE PUISSANCE COMPRENANT AU MOINS TROIS UNITÉS DE PUISSANCE
Abstract
(DE) Die Erfindung betrifft ein Leistungsmodul (2) mit mindestens zwei Leistungseinheiten (4), welche jeweils mindestens einen Leistungshalbleiter (6) und ein Substrat (8) umfassen. Um den erforderlichen Bauraum des Leistungsmoduls zu verringern und eine Entwärmung zu verbessern, wird vorgeschlagen, dass der jeweils mindestens eine Leistungshalbleiter (6), insbesondere stoffschlüssig, mit dem jeweiligen Substrat (8) verbunden ist, wobei die Substrate (8) der mindestens zwei Leistungseinheiten (4) jeweils unmittelbar stoffschlüssig mit einer Oberfläche (24) eines gemeinsamen Kühlkörpers (26) verbunden sind.
(EN) The invention relates to a power module (2) having at least two power units (4), which each comprise at least one power semiconductor (6) and a substrate (8). In order to reduce the installation space required for the power module and to improve cooling, it is proposed that the respective at least one power semiconductor (6) is connected, in particular in a materially bonded manner, to the respective substrate (8), wherein the substrates (8) of the at least two power units (4) are each directly connected in a materially bonded manner to a surface (24) of a common heat sink (26).
(FR) L'invention concerne un module de puissance (2) comprenant au moins deux unités de puissance (4) qui comprennent chacune au moins un semi-conducteur de puissance (6) et un substrat (8). L'invention vise à réduire l'espace d'installation nécessaire au module de puissance et à améliorer le refroidissement. À cet effet, ledit semi-conducteur de puissance respectif (6) est relié, en particulier par une liaison matérielle, au substrat respectif (8), les substrats (8) desdites unités de puissance (4) étant chacun directement reliés par liaison matérielle à une surface (24) d'un dissipateur thermique commun (26).
