摘　　要：随着电子设备舱舱内设备数量不断增加,电子设备舱热耗也在不断上升,而由散热所引发的噪声问题日趋显著。目前,已有部分电子设备舱热耗达到数十千瓦,增加方舱空调等散热设备的设计方式已无法满足设备散热和人员舒适性的双重需求。文中提出一种新的电子设备舱低噪声散热设计技术,通过安装液冷源和不同形式的风机盘管,实现高热耗电子设备舱的低噪声散热设计。以某雷达电子设备舱的设计过程为例,介绍了该技术的实现形式,并通过仿真及测试验证了该设计方法的效果。结果表明:在满足设备散热需求的同时,人员工作区域噪声可控制在60 dB(A)左右,为电子设备舱散热设计提供了一种可行、有效的方法。With the increasing number of electronic devices in the electronic equipment shelter,the thermal consumption of shelter is also rising,and the noise problem caused by heat dissipation has become increasingly prominent.At present,the thermal consumption of some electronic equipment shelters has reached tens of kilowatts,and the design approach of increasing cooling equipment such as air conditioners can no longer meet the dual requirements of equipment cooling and personnel comfort.In this paper a new low-noise heat dissipation design technology for high thermal consumption electronic equipment shelter is proposed.By installing liquid cooling sources and different types of fan coil units,a low-noise heat dissipation design is achieved for electronic equipment shelter with high heat consumption.Taking the design process of a radar electronic equipment shelter as an example,the implementation form of this method is introduced in this paper and the effectiveness of design method is verified through simulation and testing.The results show that while meeting the equipment’s cooling requirements,the noise in the personnel working area can be controlled at about 60 dB(A),which provides a reliable and effective method for the heat dissipation design of electronic equipment shelter.
