摘　　要：电路板元器件在高温环境工作时,长时间的热量积累会加快元器件老化速度。为了有效地降低电路板可编程逻辑芯片表面温度,设计了一款柱齿状散热器,通过对散热器的柱齿宽度、柱齿高度和柱齿间隙进行关联性分析,采用响应面优化算法,得出柱齿宽度、柱齿高度和柱齿间隙的最优设计值,经过热仿真分析和试验验证表明,柱齿状散热器满足散热设计要求。When the components on the circuit board work at high temperatures,long-term heat accumulation will accelerate the aging rate of components.To effectively reduce the surface temperature of PLD(programmable logic device),a column toothed radiator is designed.Through the correlation analysis of the column tooth width,the column tooth height and the column tooth clearance,the optimal design value is obtained by adopting RSM(response surface methodology)optimization algorithm.Thermal simulation analysis and experimental verification show that the column toothed radiator meets the heat dissipation design requirements.
