Abstract

The utility model relates to a radiator with thinner fins which comprises a base and a plurality of fins. The base is provided with a plurality of grooves separated with intervals. The edges of the fins is locally folded to form bend parts which is overlapped on the surface of the fins to increase the thickness. The fins are fixed in the grooves relative to the base via the local edges and bend parts, thereby forming a radiator with thinner fins, increased density and higher heat emission efficiency. The width of the grooves on the base is enlarged to simplify the process and reduce the manufacturing cost.
