Abstract: A heat sink for a high voltage switchgear includes: a body. The body is centered around a central axis that extends in an axial direction from a first outer surface of the body to a second outer surface of the body. At least one third outer surface of the body extends from the first outer surface to the second outer surface. At least one air channel extends through the body from the first outer surface to the second outer surface. The at least one air channel is surrounded by the at least one third outer surface.
