Structure of Heat Sink

Abstract

An improved structure of heat sink, which comprising: a heat conduction layer and cooling fins; the heat conduction layer of an elongated shape is designed in a manner that a heat source is incorporated into the central zone, and convection holes with equidistant arrangement are distributed peripherally; every convection hole is of obround shape and located in parallel with the long side of the heat conduction layer; the cooling fins are arranged into sheets and attached below the heat conduction layer, with the length the same as the long side of the heat conduction layer, namely, the cooling, fins are arranged in parallel with the long side of the heat conduction layer.
