Abstract
In a liquid cooled thyristor column in which disk thyristors are stacked along with heat sinks with the disk thyristors and heat sinks held elastically together each heat sink is equipped with a laterally projecting heat pipe having its free end emersed in a coolant line, with the free ends of the heat pipes secured to the coolant lines by means of a membrane. Each heat pipe includes an intermediate section having electrical insulating material and a tube section of elastic material adjacent the heat sink thereby permitting impure cooling liquids to be used.
