ABSTRACT:
A stack including a semiconductor element and the associated components is held within a lower portion of a hermetic envelope between its side wall and a closure block movably secured to its opposite side wall to close an opening on the latter and is immersed into a cooling liquid boilable adjacent the operating temperature of the semiconductor element. A pressing plate fixed to the opposite side wall resiliently presses the closure block to apply a compressible contact force to the semiconductor element. The stack may be sandwiched between two closure blocks closing the opposite opening on the bilateral walls of the lower envelope portion and pressed toward each other by two spherical segment of resilient material arranged back-to-back. Alternatively the stack may be carried between the bilateral envelope walls through a resilient spherical segment.
