Abstract: Heat sink is the key component of heat removal from CPU rapidly and has became one of the main problems in the new generation of electronic chips.Computational fluid dynamic is used in this paper to simulate the flow and heat transfer of radiation-shaped heat sinks to explore overall thermal and fluid performances under various parameters such as fin profile,density of fins,fin thickness.Finally,natural convection and instantaneous dynamic characteristics are also analyzed.
