ABSTRACT OF THE DISCLOSURE Disclosed is a cooling capsule for use with thy- ristors wherein the capsule includes a core having first and second end faces adapted for heat-conducting connection to a thyristor and wherein a cooling coil is cast within the core for providing a flow path for liquid coolant therethrough. The cooling coil has first and second ends extending from the core to provide inlet and outlet openings and has subsections which are located in the core in respective spaced first and second planes which extend in the vicinity of and approximately parallel to the first and second end faces of the core, respectively. The cooling coil is formed as a helix which extends from the first end to a region at which it turns around and extends to the second end in the manner of a bifilar winding, the subsections which carry coolant in opposite directions being alternatingly arranged adjacent one another. Subsections of the helix are arranged to lie in the first and second planes and are formed so as to be at least partially straight. A known cooling capsule uses spiral coils in the first and second planes which are joined together which has the disadvantage that the end faces are cooled differently. Furthermore, in such known device, the temperature distribution in each heat transfer plane between the capsule and each thyristor is not constant. In the present invention, the end faces are at approximately the same temperature.
