3) Data center liquid cooling service

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)

6Anhui 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
