Description
Technical Field

With the introduction of intelligent manufacturing 2025 and the acceleration of the technical application field of 5G communication, most of the devices currently used for 5G edge computing and distributed cloud computing are deployed in a manner of being installed in a machine room environment in a building for operation, and are also installed outdoors in an integrated cabinet manner. Some users are limited by places and have to deploy the edge computing device in offices or laboratories, in addition, a safe distance needs to be kept between people, many workers need to work at home, and users are considering deploying the home-type edge computing device, so that the edge computing device suitable for working in offices, laboratories and other home places is needed in the market at present. However, computing devices such as high-performance computing and small-scale super computing have high power density and relatively high operating noise, which causes inconvenience for users.
At present, most commercial users have to consider building a hollow glass house to isolate a temporary computing equipment laboratory to install edge computing equipment, so that the construction difficulty is high, the construction period is long, the precious building area is occupied, and if the rental period is due, the original building needs to be dismantled and restored, so that the use of the users is very inconvenient. In addition, when the small-sized super computer is put into operation formally in the glass room, dust enters the computer quickly, workers still have high noise of equipment when entering the glass room, and finally the method is not an ideal solution, so that inconvenience in use and resource waste due to use are caused. In addition, the computing modes of users are intermittent, so that the industry does not consider to deploy expensive uninterruptible power supplies for delayed power supply, and the users all run in the commercial power environment in the computing task execution process, so that the energy consumption is high.
In the past, a metal-enclosed cabinet is used for installing edge computing equipment, so that the noise problem is relieved to a certain extent, but the total air volume of the cooled equipment is insufficient, so that a high-density high-performance computer cannot normally operate and cannot be independently deployed in an office and a laboratory for stable operation, and therefore, the contradiction between heat dissipation and noise causes that the existing edge computing device cannot meet the indoor use requirement.
The noise of the edge computing device in normal operation is basically kept near 95-100 decibels, sound wave interference noise in a frequency range audible to human ears is considered, a passive noise reduction technology is adopted to realize sound insulation and noise reduction, and the noise reduction mechanism of the typical passive noise reduction technology is mainly six types, namely a resistive muffler, a reactive muffler, an impedance composite muffler, a micro-perforated plate muffler, a small hole muffler and an active muffler.

The problem can be well solved only by considering the device which ensures that the lengths of the air inlet channel and the air exhaust channel are enough and gives consideration to two technologies of ventilation and noise elimination, and meanwhile, the annual operation working condition is required to be met.
In conclusion, an edge computing device with a higher power density and a better noise reduction effect is urgently needed in the market to meet the requirements of the use environment of the micro super computing equipment.
