a. Introduction of Industry and Products
With the rapid increase in single-chip and hyper-node power consumption, liquid cooling technology has
become the inevitable solution for data center heat dissipation as it overcomes the physical limitations of air
cooling. Data center liquid cooling primarily employs three approaches: cold plate cooling, immersion cooling,
and spray cooling. In immersion cooling, servers are fully submerged in an insulating medium, where heat is
absorbed and transferred through the circulating cooling fluid before being dissipated by the cold source. Cold
plate cooling involves direct contact between cooling plates and chips; the cooling liquid circulates through
microchannels in the plates, absorbs heat, and is then delivered via pipelines to the CDU, where it exchanges heat
with the cold source to complete the cooling cycle. Key components of liquid cooling systems include cooling
cabinets, CDU, manifolds, cooling plates, quick connectors, and piping systems.
b. Company industry position and business promotion
With the explosive growth of AI computing power, particularly the soaring demand for high-power cooling
solutions, the company has focused its efforts on the liquid cooling sector for supercomputing centers. It applies
core technologies—including system integration, software algorithms, sealing materials, and high-efficiency heat
exchange—to this field.
In the liquid cooling sector for supercomputing centers, the company possesses expertise in both plate-type
and immersion liquid cooling technologies, offering a diverse range of liquid cooling solutions. It has established
a comprehensive product portfolio encompassing liquid-cooled racks, CDU(Cold Liquid Distribution Units),
Anhui Zhongding Sealing Parts Co.,Ltd. Abstract of the Annual Report 2025
microchannel cooling plates, quick-connect connectors, and pipeline systems for secondary-side cooling, along
with standardized test load products. To date, the company has secured multiple orders for cooling plate and
immersion liquid cooling solutions, with total order value reaching approximately RMB 38 million. The company
is actively expanding its production capacity to ensure timely delivery of orders both domestically and
internationally.
(2) The Auto Industry Situation during the Reporting Period
In 2025, automobile production and sales reached 34.531 million and 34.40 million, with year-on-year growth of
million, respectively, up 10.2% and 9.2% year-on-year. In 2025, the cumulative production and sales of new energy
vehicles in China will be 16.626 million and 16.49 million, respectively, up 29% and 28.2% year-on-year. (Data from
China Association of Automobile Manufacturers statistical analysis)
