Abstract
The present invention proposes a surrounding type fin-retaining structure of heat radiator comprising a retaining tool and a plurality of fins. The retaining tool is integrally formed. The fins are formed by punching metal sheets. Each of the metal sheets comprises a main body provided with frills. Each of the frills has a groove with gaps at a predetermined position thereof. After the plurality of fins are tightly arranged together, the grooves on the frills will be tightly joined together to form a surrounding and closed shape. The retaining tool is manufactured to have the same size and shape as those of the grooves. The retaining tool is placed into the grooves and retained therein to fix the fins of a heat radiator.
