## About

Based in Beijing, China, and founded in 2024, Zhongke Qiansheng (Beijing) Technology Co., Ltd., trading as Quadringa, focuses on developing liquid cooling technologies. Its founder Yaqing Rao is a serial entrepreneur with extensive engineering, marketing, and management experience in the power, data center, and other fields. In August 2026, it raised tens of millions of CNY in an Angel+ funding round from Cowin Capital, Tang Xing Capital, and Beijing Industrial Developing Investment Management. Quadringa specializes in advanced liquid cooling technologies, emphasizing phase change liquid cooling systems designed for high-performance computing environments. Its primary offerings include modular cabinet-level cooling solutions that utilize the evaporation characteristics of cooling fluids to effectively dissipate heat in high-density server configurations. These products are specifically designed for rapidly growing sectors such as artificial intelligence, IoT, and cryptocurrency. Quadringa generates revenue through the direct sale of its phase change liquid cooling cabinets and evaporative cooling transformers. The company engages in B2B transactions with data centers and power transmission companies, offering solutions tailored to specific customer needs. Revenue is structured around project-based contracts where clients commission cooling solutions that align with their operational requirements, often involving upfront payments for initial setups and ongoing maintenance fees to ensure support and efficiency. The company will use the Angel+ funding to promote the independent production of core phase change cooling components, build key component R&D and manufacturing capabilities, and enhance the ability to deploy on a large scale for multiple application scenarios. Also, it will focus on the green and energy-saving thermal management needs of electronic information equipment and electrical equipment, continuously promoting the independent development, productization, and large-scale application of phase change cooling technology, providing technical support for the development of industries such as artificial intelligence, new energy, and advanced manufacturing.
