The present invention provides a wind cover locking element structure of heat radiator comprising a locking element, a heat radiator, a wind cover, and a socket. Projective sheet bodies are disposed at both sides of openings on two sideboards of the wind cover. The sheet bodies have abutting and positioning functions. When the locking element and the socket are locked together, the sheet bodies can abut against the locking portions of the locking element so as to be positioned, thereby reducing the shift between the locking element and the heat radiator. The heat radiator can thus be accurately stuck on a CPU.

Wind cover locking element structure of heat radiator

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.

Retaining structure of heat-radiating fins

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.
