加装装饰罩和粉刷涂料是散热器装饰的主要形式。实验研究了不同型式装饰罩对散热器性能的影响,给出了不同型式装饰罩安装修正系数;分析了装饰罩顶部开孔率对散热性能的影响,得出75%左右开孔率对散热器散热性能影响较小。给出不同涂料的黑度值,散热器外表面涂刷非金属涂料可以强化辐射换热,但是会影响散热器热传导。
加裝裝飾罩和粉刷塗料是散熱器裝飾的主要形式。實驗研究瞭不同型式裝飾罩對散熱器性能的影響,給齣瞭不同型式裝飾罩安裝脩正繫數;分析瞭裝飾罩頂部開孔率對散熱性能的影響,得齣75%左右開孔率對散熱器散熱性能影響較小。給齣不同塗料的黑度值,散熱器外錶麵塗刷非金屬塗料可以彊化輻射換熱,但是會影響散熱器熱傳導。

Instal ation of decorative covers and radiator paint coatings are the main forms of radiator decoration. Experimental study on the effects of different types of decorative cover on the performance of the radiator, get the instal ation correction factor of different types of decorative cover. Then analyze the influence of the top opening rate of the decorative cover acting on thermal performance. Come to conclusion that the 75%holed ratio has little effect on the performance of radiators. Given the darkness value of different coating, so palette non-metal ic coating on the radiator external surface can strengthen the radiation heat transfer, but it wil affect the heat conduction.
