Computing Center Cold Plate Liquid Cooling System Liquid Cooling Hose

 As a leading enterprise in China's hydraulic and fluid conveyance industry, Letone Hydraulic, based in Luohe, has over 20 years of experience in material R&D and process refinement. It has built a full matrix of hydraulic hose products, covering scenarios from data center liquid cooling systems to oil and gas drilling sites, industrial high-pressure circuits to special fluid conveyance applications, delivering highly reliable and customizable fluid conveyance solutions for diverse industries.                    

Exclusive Product Line for Data Center Liquid Cooling Scenarios: Adapted to High-Density Deployment Requirements

Against the backdrop of widespread high-density deployment in data centers, where GPU power consumption has exceeded 1000W, cold-plate liquid cooling has become the mainstream configuration. Letone Hydraulic's pre-developed ‌high-purity liquid cooling hose‌ series serves as the core support for stable operation of computing systems. Unlike ordinary industrial hoses, this product series strictly controls ion precipitation indicators from the raw material stage, and is formulated with UL94 V-0 flame-retardant rubber. It perfectly fits three core installation positions: the connection between CDU and rack manifold, the connection between rack manifold and server node, and the short pipe at the front end of the cold plate. It not only compensates for displacement deviation caused by thermal expansion and cold contraction of the system, but also meets the flexible connection requirements for hot swapping of servers. For computing scenarios with different power densities, Letone Hydraulic also provides tiered adaptation solutions: ‌EPDM liquid cooling hoses‌ are the preferred choice for ordinary AI clusters below 30kW, delivering excellent cost performance with a wide temperature range from -40°C to 120°C. For ultra-high-density training clusters above 80kW, ‌PTFE hydraulic hoses‌ are used as core connecting components. Leveraging the PTFE inner liner's properties of high and low temperature resistance and zero precipitation, they can withstand continuous erosion by high-flow cooling media for a long time. For special immersion fluorinated liquid scenarios, the dedicated product line consisting of ‌PFA high-purity hoses‌ and ‌FEP corrosion-resistant hoses‌ completely eliminates the risk of medium contamination, ensuring long-term stable insulation performance of fluorinated liquid. Currently, this series of liquid cooling hoses has obtained UL certification, with all rubber compound flame retardancy and thermal stability indicators meeting international standards, significantly enhancing the international competitiveness of China's core computing components.

Letone Hydraulic has optimized the size and performance of all liquid cooling hoses to adapt to the narrow space inside data center cabinets. The core specifications fully cover mainstream deployment requirements, as detailed below:

Industrial High-Pressure Hydraulic Hose Series: Reliable Performance in Harsh Working Conditions

Beyond the liquid cooling track for data centers, Letone Hydraulic also maintains technological leadership in the traditional high-pressure fluid conveyance sector. Its ‌steel wire braided hydraulic hoses‌ and ‌steel wire spiral high-pressure hoses‌ strictly comply with ISO 18755 standards, with some models certified by MSHA for mining safety. The outer layer is made of vulcanized wear-resistant synthetic rubber, which can operate stably for a long time in environments ranging from -40°C to 100°C, effectively avoiding common failures of ordinary hoses such as burst, leakage and outer layer cracking. To meet the special demands of oil and gas drilling operations, Letone Hydraulic's API 7K certified rotary drilling hoses can withstand a maximum working pressure of 15000psi, suitable for extreme working conditions such as mud conveyance, cementing and fracturing. Meanwhile, the API-17K large-diameter offshore jumper hose project under development has completed the installation and commissioning of core equipment, laying a solid foundation for future expansion in the offshore oil and gas pipeline market.

For mainstream hydraulic hoses targeting industrial high-pressure scenarios, Letone Hydraulic's core specifications fully meet the interface requirements of mainstream domestic engineering equipment, with supplementary parameters as follows:

Full-Process Quality Control System: Building Technical Barriers for Domestic Hydraulic Hoses

From independent R&D of material formulas to full-process performance control, Letone Hydraulic always takes "adapting to extreme working conditions" as the core R&D direction for its products. Whether it is the low-precipitation formula optimization of ‌EPDM liquid cooling hoses‌, the bending resistance structure upgrade of ‌PTFE hydraulic hoses‌, or the precision control of ‌PFA high-purity hoses‌ and ‌FEP corrosion-resistant hoses‌, every product has passed hundreds of thousands of pulse tests. In core scenarios such as data centers, oil and gas drilling and high-end manufacturing, Letone's products are gradually replacing imported brands, providing solid support for the independent controllability of China's industrial fluid conveyance system.
