Construction of a heat sink for electronics cooling is formed of parallel metal plates in a holder

摘要

The heat energy generating chip [21] is located on a circuit board [2] and placed over it is a thermally dissipating heat sink [1]. Air flow is forced over the heat sink by an electrical fan [3]. The heat sink has a number of metal plates [12] in a retainer [11] that maintain a gap between adjacent plates for air to pass.
