Abstract：Aiming at the problems of servo driver higher heat and temperature，the CFD analysis technology based on the experience of engineering applying to the optimization design for heat-sink was investigated. The finite volume method for the numerical simulation was adopted to research the influence of the shape and the size of the heat-sink under natural convection conditions on thermal efficiency. The optimal design was chosen contrasted the simulation analysis of the distribution of the temperature field. The results indicate that，the heat radiation efficiency is improved 6.8%，using the simulation analysis based on the experience of engineering design，under the same conditions of processing technology and economic. The reliability of the products is increased.
