电源模块散热方法有哪些

Source: Time:2019-06-17 16:17:30 views:

圣羽翔小编告诉大家电源模块散热方法有哪些?希望通过这篇文章,能解决你电源模块发热过于严重的问题。

  电源模块在电压转换过程中具有能量损耗,导致模块发热引起的热量降低,电源转换效率降低,影响电源模块的正常运行,但在什么情况下会导致电源模块发热更严重?
  电源模块
  l使用线性电源模块;

  l加载流量;

  l负载太小:负载功率小于模块功率输出功率的10%,很可能导致模块发热(效率太低);

  电源模块

  l环境温度过高或散热差。
  电源模块散热方法:

  1)使用线性电源添加散热器;

  2)提高功率模块负载,确保不低于额定负载的10%;

  3)降低环境温度,保持良好的散热。
