An internally coolable component for a gas turbine with at least one cooling duct, on the inner surface of which swirl elements are arranged in the form of turbulators which extend transversely with respect to the main flow direction of a coolant is provided. In order to reduce pressure losses for the coolant in the cooling duct, pins with different heights are set up between the turbulators.

A cooling circuit for removing waste heat from a cooling device of an electromechanical converter is provided. The cooling circuit includes a chilling medium, a cooler for extracting heat from the chilling medium, a return connecting the cooling device of the converter to the cooler and conducts warm chilling medium, a feed connecting the cooler to the cooling device of the converter and conducts cool chilling medium, and an absorption chiller for extracting heat from the chilling medium. The absorption chiller is driven by the heat of the warm chilling medium that is in the return.
