Design of a low-noise cabinet based on an integrated independent air duct heat dissipation architecture

Abstract The current processing cabinet mainly adopts the distributed heat dissipation architecture, the plug-in unit is forced by air cooling by the fan equipped with the plug box, then the fan at the top of the cabinet will discharge the heat out of the plug box. Under this architecture, there are many internal noise sources in the cabinet, and the whole machine is noisy. The noise of the cabinet when the door opens or closes is inconsistent; when the door opens, the noise is louder. In this paper, a kind of integrated independent air duct heat dissipation architecture is proposed, the fan provided by the plug box is eliminated, the feasibility of the structure is verified by the software of thermal analysis software, a low-noise cabinet is designed to reduce the noise of the whole machine and solve the problem of excessive door opening noise.
