Liquid cooled power electronic circuit comprising a stacked array of directly cooled semiconductor chips

摘要

A stacked array (10/40) of channeled semiconductor chips (12a-12d) defining a power electronic circuit is mounted in a sealed container (50) provided with inlet and outlet passages (66, 68) for liquid coolant. Leadframe terminals (58a-58f, 64a-64b, 70) supported by the container (50) engage selected terminals (14, 16, 18) of the semiconductor chips (12a-12d) and form leads for mounting the container (50) on a circuit board having electrical and fluid interconnects.
