Abstract

The present invention proposes a retaining structure of heat-radiating fins, wherein a heat-radiating part is formed by stacking a plurality of sheet type heat-radiating fins. Each of the heat-radiating fins has an upper bent portion and a lower bent portion. The two bent portions are used to form a gap, and can also be used as the joining portion between two adjacent fins. Through holes are disposed on each of the heat-radiating fins. At least a retaining tool is provided. Near two ends of the retaining tool are bent to form hook ends. The two hook ends of the retaining tool are retained in the through holes of corresponding fins to let the retaining tool straddle the bent portions of the fins. Grooves are respectively disposed at the upper and lower bent portions so that a body portion of the retaining tool can be embedded therein.
