Digitimes Server Manufacturers Step Up Layout In Liquid Cooling Thermal Management
Liquid cooling thermal management is reshaping the server heat dissipation supply chain ecosystem, drawing widespread investment from industrial players. High-end AI servers equipped with high-performance GPU accelerators feature sharply increased power consumption. With superior heat conduction efficiency, liquid cooling effectively dissipates internal heat, prevents component damage and secures stable performance and reliable operation, which perfectly matches the demands of GPU server liquid cooling and high density server cooling scenarios.
Two-phase direct liquid cooling technology has emerged as a mainstream solution, greatly lowering liquid leakage risks and boosting industrial investment confidence. As a direct heat dissipation method, it transfers heat via direct contact between liquid and heat sources, relying on high heat capacity and thermal conductivity of cooling fluid and outperforming traditional air cooling in efficiency and energy saving. It is mainly divided into single-phase and two-phase types: single-phase keeps coolant in liquid state throughout heat exchange, while two-phase leverages low boiling point fluid for phase change, with coolant evaporating to absorb heat and condensing back to liquid. Featured with non-conductive, low boiling point dielectric fluid, two-phase liquid cooling supports high thermal design power, cuts leakage risks and enhances system stability, though it requires upgraded pressure resistance, explosion-proof structure and optimized welding processes. Representative products include Accelsius’ NeuCool system and ZutaCore’s HyperCool technology, with Wiwynn also cooperating with ZutaCore to adopt this solution, which shows great potential in high-end servers despite being in technical demonstration stage.
AI servers have taken the lead in adopting liquid cooling solutions, with thermal design shifting from single server units to full cabinet assembly mode. In the past, air cooling dominated server heat dissipation, but liquid cooling requires integrated pipeline layout and structural adjustment, pushing thermal design upgrade to full cabinet layer. This integrated design helps manufacturers strengthen core capabilities and drives more enterprises to increase investment in heat dissipation technologies; in the future, server suppliers need to master server development, full cabinet design and mature data center liquid cooling solution to cater to diverse demands, including container data center liquid cooling.
Professional heat dissipation integration capability has become a core advantage for manufacturers to win orders, as liquid cooling market demand keeps rising and closer supply chain cooperation is formed. According to DIGITIMES Research, the industrial chain consists of major participants: component suppliers, thermal solution providers and end demand clients, who jointly promote stable operation of various liquid cooling for data center projects. Main component suppliers deliver core parts including heat dissipation modules and liquid cooling plates, covering brands engaging in cold plate liquid cooling, cabinet manufacturers and liquid cooling fitting producers, with many extending downstream and traditional air cooling part makers stepping into liquid cooling manifold manufacturing.
Thermal solution providers design customized systems and assemble complete cooling facilities, with most professional one-stop service suppliers being European and American brands; more enterprises are integrating cabinet design and cooling schemes to enrich product lines and better support the construction of complete data center liquid cooling system. Server OEM manufacturers, as major demand-side participants, lead most thermal design work and cooperate closely with upstream suppliers to balance performance, energy consumption and cost for reliable cooling schemes.
Core trends are leading the server heat dissipation industry’s development: liquid cooling technology is moving toward unified standardization to regulate the market, continuous technical investment and cross-industry cooperation are promoted to tackle difficulties and improve energy efficiency, and the supply chain is stepping into large-scale capital competition to strengthen risk resistance and competitiveness, further fueling the steady progress of the AI data center cooling industry worldwide.
