Abstract

The utility model relates to a radiating fin which is formed by a metal flat plate with a plurality of upwardly vertical fins around through impact forging and folding. The fins are arranged by means of internal and external ring shapes and distant complementary shape, and the center of a bottom board is provided with a plurality of riser vents. When the heat source of a wafer is led in from the bottom contact side of the radiating fin, the fan which is pre-arranged above the radiating fin sends cold wind to the inward concave space of the radiating fin. The fins of the internal and the external layers which are in the distant complementary state can form a proper wind baffle to stop a part of the wind in the inward concave space, and the other part of the wind is downwards led to the circuit board to realize the heat dissipation of the wafer or an electronic element through the riser vents at the bottom board. The ward wind after heat dissipation can be dissipated around or under the radiating fin through around fin gaps and the riser vents to achieve the intention of low cost and good heat dissipating effect.
