A heat sink with undulating fins is provided. The heat sink according to this invention includes a thermally conductive base plate having a top surface and a plurality of thermally conductive fins. The fins extend upwardly from the top surface. Each fin is integral with the base plate and has an undulating surface. The fin surfaces of adjacent fins define a space for passing a cooling fluid between them.
