1. A device for cooling a bus bar, said device comprising:
a heat absorption element configured to rest in form-fit manner on the bus bar;
a heat output element configured to rest in a form-fit manner on a heat sink and aligned in parallel to the heat absorption element;
compression springs guided by a guiding pin and arranged between the heat absorption element and the heat output element to apply an additional contact force; and
a heat transportation system constructed from copper or designed as a heat pipe and materially connecting the heat absorption element and to the heat output element in a thermally conductive manner by welding or soldering.
