摘　　要：工业生产中常用的加热装置热板的表面温差均匀性是一个的重要技术指标.由于加热元件的功率大小与分布是热板设计的重要参数,因此它的制造误差对其性能影响很大.针对影响热板加热均匀性技术指标的误差因素进行了相关研究.通过温度场的敏度分析得到了计算热板温度场热流敏度的控制方程,从而可进一步准确计算出热板发热元件热管的功率大小与分布误差对热板加热均匀性的影响程度,对指导相关的热板设计、控制误差及保证热板均匀性具有一定的指导意义.Electrical plate is an important heating equipment often used in industrial manufacturing,and its surface temperature uniformity is one of the important technical specifications.Out of consideration that the power level and space distribution of heating components such as heating pipe are the important parameters for the plate design,this paper exerts some efforts on studying the error factors influencing the uniformity of heating for electrical plate.It obtains the governing equations for calculating heat flow sensitivity of electrical plate temperature field through sensitivity analysis of temperature field,based on which the influence of error arising from the power level and space distribution on uniformity of heating accurately is calculated.The result may offer as a valuable reference for the electrical plate design,error control and securing uniformity of heating.
