COOLING SYSTEM AND COOLING ARRANGEMENT

A cooling system having a closed cooling duct system between a main inlet and a main outlet for cooling medium, and includes at least one cooling duct section. The cooling system includes individual modular elements, each including at least one partial segment. In a connecting region of the individual modular elements, their respective at least one partial segment connect continuously to form the at least one cooling duct section. Adjacent individual modular elements each have, in the connecting region, a complementary element of a common media coupling, in which, in a detached connection between two adjacent individual modular elements, the respective partial segment contained in an individual modular element is sealed in media-tight fashion at least in its connecting region, and in a coupled connection between the adjacent individual modular elements, in the connecting region, a passage for a flow of cooling medium is opened inside the media coupling.
