摘要

通过电子元件封装的冷却空气所产生的噪音有两个来源。其中一个噪声源是轴向或离心式风机的噪声。这种噪音可能有音调和随机成分,并且强烈依赖于风扇放置在机组中的方式以及其运行距离设计工作点的远近。通常,这是主要的噪声源。另一种噪声源由于空气在机组中的紊流而产生随机噪声。由于湍流气流还负责部件与气流之间的换热,因此我们可以将这部分噪声视为由于冷却而产生的不可减噪声。如果要消除风扇噪声,则必须保留这部分噪声。因此,在不可消除的噪声和机组的冷却之间有一种关系。但是风扇的噪音也必须考虑在内。针对不可消噪声问题,建立了与总气流相关的噪声与冷却要求的关系。

Noise and cooling in electronics packages
The noise produced by cooling air passing through electronics packages arises from two sources. One source is the noise of the air-moving fan of either an axial or centrifugal type. This noise may have both tonal and random components and is strongly dependent on the way that the fan is placed in the unit and on how close its operation is to the design operating point. Often, this is the dominant noise source. The other source produces random noise due to the turbulent flow of air through the unit. Because the turbulent airflow is also responsible for heat transfer between the components and the air stream, we can regard this part of the noise as the irreducible noise due to cooling. If fan noise were eliminated, this part of the noise must remain. There is a relation, therefore, between the irreducible noise and the cooling of the unit. But the fan noise must also be considered. The relation between total airflow related noise and cooling requirements is developed in this paper for the irreducible noise.
