摘要
分析了引起电解电容发热的主要原因,提出了降低电解电容器温升的方法。通过剖析电解电容内部结构,进一步分析了常用散热方法的冷却效果,提出一种有效的电解电容散热方法,并通过实例样机测试验证了该方法的可行性和有效性。
The main reason of the heat was analyzed and proposed. Through the analysis of the electrolytic capacitors＇ analyzed, and a kind of effective cooling method of electrolytic method was validated by the prototype test. a method to reduce the temperature rise of electrolytic capacitors was internal structure, the cooling effect of common cooling methods was capacitor was put forward. Feasibility and effectiveness of the proposed
