为研究散热器装饰罩对散热量的影响，选择了几种常见装饰罩进行了试验，得出结论：（１）原苏联在测试散热器装饰修正系数时的测试条件和采用的方法与国际标准不同，因此原苏联文献中的散热器装饰修正系数不完全适用于我国，不能简单照搬；（２）合理地选择散热器装饰罩的形式，可使散热器的散热量在加罩之后保持不变或变化很小。 In order to study the effect of heat sink decorative cover on heat dissipation, several common decorative covers were selected and tested to arrive at the conclusion: (1) Test conditions, methods and international standards used by the former Soviet Union when testing radiator decoration correction coefficients Different, so the radiator decoration correction coefficient in the former Soviet Union literature is not entirely applicable to our country, can not be simply copied; (2) a reasonable choice of radiator cover shape, can make the radiator heat dissipation remained unchanged after the cover Or changes are small.
