    型材散热器的噪音

      型材散热器中风扇除了散热效果之外,风扇的工作噪音也是众人广泛关心的问题。下面介绍下影响型材散热器噪音的因素。


      型材散热器风扇噪音是风?#28909;?#21153;时发生杂音的大小,受多范围的要素反应,部门为分贝(dB)。测量风扇的噪音时需求正在噪音小于17dB的消音室?#22411;?#27490;,间隔风扇一米,并沿风扇转轴的方向对于准风扇的进气口,采纳A加权的形式停止测量。风扇噪音的频谱特点也很主要,因而还需求用频带仪记载风扇的噪音频次散布状况,?#35805;?#35831;求风扇的噪音要过分的小,并且不能具有异音。


      型材散热器风扇噪音与冲突力、气氛活动相关。风扇转速越高、风量越大,形成的噪音?#19981;?#36234;大,此外风扇本身的震动也是没有可无视的要素。当然质量上乘的风扇的本身震撼会很小,但后面两个者却是难以克制的。要处理某个成绩,咱们能够试验运用分寸较大的风扇。应正在正在风量相反的状况下,微风扇正在?#31995;?#36716;速时的任务噪音要小于小风扇正在高转速时的任务噪音。此外一度咱们简单疏忽的要素是风扇的轴?#23567;?#22240;为风扇高速转动时转轴和轴承之间要地突碰撞,因为也是型材散热器风扇噪音的一个主要来源。
