Yinlun The Underrated Leading Player in AI Liquid Cooling with Explosive Performance Potential
Yinlun is currently the most undervalued core leader in the AI liquid cooling sector, featuring the best fundamental certainty and the highest performance elasticity. Leveraging 40 years of core plate heat exchanger technology in vehicle thermal management, the company has seamlessly entered the high-barrier track of CDU liquid cooling heat exchanger for AI data centers. As the industry shifts from balanced supply and demand to a structural supply shortage, overseas giants face extremely slow capacity expansion, forming rigid industry supply constraints. Boasting world-class heat exchange performance comparable to Alfa Laval, independent core equipment manufacturing capability, global localized production capacity and ultra-fast line construction cycles, Yinlun stands as the exclusive domestic qualified supplier for leading North American G clients with highly certain large-order delivery in Q3. With its traditional automotive thermal management business providing steady revenue support, the company’s liquid cooling second growth curve is at an explosive inflection point, delivering clear long-term market value growth potential.
The industry has ushered in a definitive turning point, with core components for data centre liquid cooling system entering a supply-demand reversal and set to face widespread shortage starting in 2027. Driven by the high-density upgrading of AI large model computing clusters, liquid cooling has evolved from an optional solution to a mandatory infrastructure for high-performance computing. As the highest-value and highest-barrier core component in liquid cooling systems, CDU heat exchangers are witnessing a fundamental shift in industry supply and demand patterns. Global high-end heat exchanger capacity is highly concentrated in three overseas leaders, whose limited output cannot match the rapidly growing AI computing demand, resulting in intensifying market gaps starting from the second half of 2026.
Widely underestimated by the market, high-precision rear door heat exchanger and CDU heat exchanger products involve profound industrial know-how in material selection, plate structure design, corrugated modeling, flow field simulation, pressure resistance and anti-leakage craftsmanship, rather than ordinary standard parts. Accounting for 30% of the total value of CDU systems, heat exchangers represent the most valuable single component in the liquid cooling industrial chain. With rigorous performance verification under the extreme height limitation of 602mm equipment for top-tier clients, Yinlun adopts a 276-layer precision plate stacking design to achieve ultra-high heat dissipation power of 700kW, becoming the only domestic manufacturer with performance fully benchmarking global industry leaders and breaking long-term overseas monopoly.
Delivering reliable thermal management for high-density server rooms, optimized data center rear door cooling solutions rely on Yinlun’s unparalleled five-dimensional moat covering technology, equipment, capacity, global delivery and premium client resources. Differentiated from concept-driven peers without independent production or core craftsmanship, the company’s mature vehicle-grade precision brazing, anti-leakage and high-pressure resistance technologies, accumulated over 40 years of automotive thermal management research, are perfectly transplanted to data center liquid cooling scenarios, effectively solving the industry’s common heat exchanger liquid leakage pain points and maintaining leading product stability and yield rate.
Specially adapted for high-power computing scenarios, the high-efficiency AI GPU rack rear door heat exchanger fully releases Yinlun’s independent equipment advantage. While mainstream high-end brazing equipment in the industry relies on European imports with a long 10–18 month delivery cycle restricting capacity expansion, Yinlun independently develops core brazing equipment. Free from overseas supply constraints, the company fully controls its capacity expansion rhythm, forming a decisive competitive edge amid the industry’s capacity shortage cycle.
Supporting rapid global business deployment, integrated liquid cooling CDU rear door heat exchanger products benefit from Yinlun’s industry-leading capacity construction speed and global layout. The company’s production bases in Mexico and Malaysia fully cover North American and Southeast Asian computing clusters. A new domestic standardized production line can be completed in only 4 months, and an overseas line in 6 months, far faster than the 1–2 year expansion cycle of European giants. This overwhelming capacity efficiency makes Yinlun the optimal and almost exclusive supplier for major clients to fill the market supply gap.
Realizing precise temperature control and stable fluid circulation, customized coolant manifold rear door heat exchanger products have achieved major breakthroughs in client certification and order landing. As the exclusive domestic qualified heat exchanger supplier for leading North American computing G clients, Yinlun has completed multiple rounds of full-machine testing since May, taking the lead among all domestic competitors. Large-batch order delivery in Q3 2026 is highly certain. Meanwhile, the company is actively connecting with top computing clients including NV, XAI and H, continuously expanding its high-end customer matrix.
Empowering full-scenario server heat dissipation iteration, high-performance heat exchanger rear door rack cooling system brings explosive incremental performance space for Yinlun. The company’s traditional automotive thermal management business maintains stable operation and solid cash flow, while all growth elasticity comes from AI liquid cooling CDU heat exchangers and extended high-value businesses. Multiple conservative calculation models verify outstanding growth potential. Based solely on core G client business, the liquid cooling segment will bring substantial revenue and profit increments, driving a performance elasticity of 15%/75%/120% in 2026/2027/2028 and entering a full-scale explosive growth stage starting in 2027.
There are four major cognitive deviations in the current market, which have not priced the company’s liquid cooling business value at all. First, the track deviation: the market underestimates the high technical barriers of CDU heat exchangers. Second, the capacity deviation: the industry has a tens-of-billion-level supply gap that overseas giants cannot fill in the short term. Third, the valuation deviation: the current market value only reflects the traditional automotive business, with zero premium for the trillion-level AI liquid cooling track. Fourth, the performance deviation: the market ignores the clear quarterly performance improvement driven by client order implementation. With steady traditional business and a fully exploded liquid cooling growth curve, Yinlun holds sufficient safety margins and huge upside potential, with a clear and achievable long-term trillion market value target.
