光线追踪在系统热辐射排故分析中的应用

Ray Trace Application During Check Defect in System Thermal Radiation Analysis

针对有源系统光线在传输过程中因辐射产生的聚焦问题,引入光线追踪的方法,并结合辐射换热计算的理论,研究了聚焦点产生的温度及其分布区域,并通过实例及模拟结果的对比分析,验证该方法的可行性。结果表明:采用光线追踪分析热辐射中产生的聚焦问题,可为产品开发过程中部件的空间布置、表面处理、材料定义、结构设计等提供仿真支持,避免产生灼伤问题。

Focused on the defect of light focus in the light source system caused radiation thermal transfer,on the base of radiation heat exchange theory calculation,the paper introduced the method of ray trace to research the temperature value and distribution area of focus point.By comparing the simulation data with the sample,validate the feasibility of ray trace method.The result shows the method above could help to give the support to space distribution,surface treatment,material confirmation and structure design and avoid the default of light focus during product development.
