Summary: The research, development and manufacturing regional headquarters project for the coolers and chassis of Deepcool is located in Dongjiang Science and Technology Park, Huizhou City, Guangdong Province.It will be built into a world-class computer cooler base.
The investment amount of this project is about 380 million yuan, covering an area of 34,702 square meters, with a total construction area of about 100,000 square meters. After completion, it will mainly engage in the R&D, production and manufacturing of computer coolers, chassis, power supplies and industrial heat dissipation products. After reaching full production capacity, the annual output value will be about 780 million yuan, and the annual tax payment will be about 30 million yuan. The project investment and construction party is Huizhou Xinquansheng Precision Technology Co., Ltd.
The semi-anechoic chamber is not only a special laboratory for acoustic testing, but also an important part of the testing system. In fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the testing accuracy.

III. Main Indicators and Project Contents such as Effective Space and Background Noise
-
The indoor net dimensions after the construction of the semi-anechoic chamber are: Length (L) × Width (W) × Height (H) = 5000 ± 100 × 4000 ± 100 × 2200 ± 100 (mm).
-
When there is no abnormal low-frequency noise source interference in the external environment (i.e., the surrounding environment), the indoor background noise of the semi-anechoic chamber is Lgn(A) ≤ 10dB(A).
