Abstract: 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.
