不同结构的热模型对应的型材散热器管理解决方案

发布时间:2018/9/3     来源:电子散热器    站点:http://dfpthor.com
 
       封装结构和热模型的型材散热器需要精确建模,并且应当在选择封装之前的热设计中就使用元器件的三维表示,此外还介绍了双热阻和 DELPHI 简化热模型。下面将更详细地讨论这些模型的预测精度。

    对于具有单一热流路径的封装,如 LED 和 TO 式封装,有一种 JEDEC 标准方法 [参考文献 2] 可用于测量从结点至封装调整片的热流路径的热阻-热容模型。注意,这种方法并不直接向封装的裸露上表面提供热阻。然而,如果能通过某种方式估算该热阻,那么就可以使用 Mentor Graphics 的瞬态热测试仪 T3Ster 来创建一个考虑这种情况的 RC 阶梯热模型。
