Overview: Beijing DeepCool Technology Co., Ltd. launched the "DeepCool" brand in 2008 and the "GAMERSTORM" brand in 2010. It has been deeply engaged in the field of computer radiators for over a decade. It has been committed to providing consumers around the world with the highest-performance and most user-friendly heat dissipation solutions. DeepCool designs, develops, and manufactures a series of high-quality products, covering desktop cooling, laptop cooling, server cooling, embedded cooling, and other cooling devices. DeepCool insists on focusing on the field of electronic heat dissipation, concentrating on continuously improving its R & D and manufacturing capabilities, and never seeking diversified development in other fields unrelated to heat dissipation. The company continuously enhances its technological R & D and product design capabilities through industry-university-research cooperation and independently forming R & D teams, meeting the ever-increasing user demands and accumulating a good reputation and popularity in the market. It owns numerous sub-brands, such as Xuanbing, UltraStation, Magician. The company has mature production processes and the manufacturing capacity for multiple categories of products. By optimizing the production and manufacturing system, adjusting the production methods, improving the production processes, and combining automated equipment with auxiliary automated equipment, it has improved the flexibility and efficiency of the production line. The production process level of the firm is highly competitive, and it is among the few manufacturers across the world having the capacity to mass-produce water-cooled heat dissipation products.
GZ DP Anechoic T&E Co., Ltd. is composed of a team of acoustic experts and professional engineers who have been engaged in various acoustic technology researches at home and abroad for many years and have rich theoretical and practical experience. It has its own office building and factory, and an acoustic laboratory that complies with CNAS standards has been built in the factory, which can monitor the acoustic technical indicators of its own products and provide acoustic testing services to the outside. Through the hard work, continuous innovation, and development of the Danpin team, the acoustic laboratories designed, produced, and installed by it have products with accurate technical indicators, environmental friendliness, durability, beautiful appearance, and high technological content.
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.
