1. A radiator for cooling a transformer or a power transformer or a choke, the radiator comprising:
a plurality of mutually-parallel plate-shaped radiator elements for guiding a parallel through-flow of a coolant, said radiator elements having mutually opposite walls and edges;
at least one elastically deformable element disposed between at least an adjacent two of said radiator elements, said at least one elastically deformable element configured for counteracting an expansion of said radiator elements perpendicular to a surface of said radiator elements;
said radiator elements disposed adjacent said at least one elastically deformable element having no weld and no spot weld within said edges between said mutually opposite walls.
