Boundless Computing Power, Built on Fluid Pipelines | Letone Liquid‑Cooling Pipeline System Safeguards High‑Density Computing Infrastructure

As the construction of high‑density computing clusters accelerates worldwide, liquid cooling has become a standard solution for high‑power‑density computer rooms. A reliable liquid‑cooling system relies not only on core units such as cold plates and CDUs, but also on the pipeline network running through the entire loop. Pipeline pain points vary across scenarios, ranging from end‑point cold‑plate jumpers to main grid‑connected loops. Any inadequate fitting may trigger hidden risks including liquid leakage, blockage and deformation‑induced failure. It may even delay project construction and drive up operation and maintenance costs.

Drawing on more than two decades of expertise in ultra‑high‑pressure fluid technology, Letone Technology has developed a full‑chain liquid‑cooling pipeline system solution. It delivers targeted solutions for key scenarios including end‑to‑end jump connection, main‑line grid integration and rapid maintenance. With a tiered product matrix and customized development capabilities, Letone supplies highly‑reliable, well‑adapted domestic pipeline support for premium data centers at home and abroad.

End‑Point Cold‑Plate Jump Connection: Resolving Compatibility and Safety Pain Points in Confined Spaces

The jump‑connection hoses between cold plates and water distributors serve as the "capillaries" of liquid‑cooling systems, and also present frequent challenges during deployment and maintenance.

• Poor spatial compatibility: The interior of server racks is compact. Conventional hoses feature large minimum bend radii and are hard to route. Forced bending may damage the hose body.
• Insufficient medium compatibility: Cold‑plate loops work with diverse coolants. Ordinary inner rubber compounds tend to release precipitates that clog the micro‑channels inside cold plates.
• Inadequate safety for operation & maintenance: Densely‑arranged connection points lack clear zoning, and sub‑standard flame‑retardant performance creates potential safety hazards in data centers.

The LT800A cold‑plate‑to‑water‑distributor jump‑connection hose offers a targeted solution for this scenario:

• Flexible for easy installation: Single‑layer fiber‑braided construction delivers a small bend radius, ideal for routing within tight rack enclosures.
• High purity & chemical compatibility: Peroxide‑cured EPDM inner rubber resists water, ethylene glycol, propylene glycol and other coolants, with zero precipitation and zero swelling.
• Safe and maintainable: UL94 V‑0 flame retardant rating, weather‑proof and ozone‑aging resistant; available in red, black and blue for clear pipeline zoning and simplified maintenance.

Main Grid‑Connected Loop: Addressing Negative‑Pressure and Durability Pain Points for Long‑Distance Fluid Transfer

The secondary‑side main grid‑connected pipelines act as the "aorta" of liquid‑cooling systems, undertaking long‑distance, high‑flow coolant circulation. The industry has long been plagued by two core challenges:

• Failure under negative pressure: Negative pressure occurs during system start‑stop and flow adjustment. Ordinary hoses are prone to collapse and deformation, which interrupts fluid circulation.
• Insufficient durability: Long‑distance deployment involves harsh operating conditions. Conventional pipe materials suffer from poor wear and aging resistance, and are susceptible to cracking and performance degradation over long‑term operation.

Letone Technology has launched two grid‑connected hoses, LT800B and LT800C, forming a tiered solution to meet diverse‑grade requirements:

LT800B Grid‑Connected Liquid‑Cooling Hose Built with single‑layer high‑strength fiber‑braided reinforcement for stable pressure resistance. Its UL94 V‑0 flame‑retardant outer rubber fits standard data‑center environments. As a cost‑effective primary option for medium‑and‑low‑pressure liquid‑cooling loops, it balances reliability and construction expenditure.

LT800C Grid‑Connected Liquid‑Cooling Hose Custom‑engineered for premium negative‑pressure scenarios. It adopts a composite reinforcement structure combining multi‑layer high‑strength fiber braiding and spiral steel wire, which structurally eliminates collapse and deformation risks induced by negative pressure. Its corrugated black flame‑retardant outer rubber delivers outstanding wear resistance for long‑distance main pipelines and complex laying conditions, serving as the core configuration for secondary‑side main circuits in high‑end data centers.

Quick‑Connect Operation & Maintenance: Resolving Efficiency Bottlenecks in Deployment and Servicing

• Low deployment efficiency: Conventional flange and threaded connections are cumbersome to assemble and disassemble, consuming substantial time during deployment and maintenance.
• Restrictive handling: Ordinary connectors carry high risk of liquid leakage and are ill‑suited for blind‑mounting within high‑density server racks.

Equipped with a full portfolio of quick‑change connectors, Letone's liquid‑cooling pipeline system delivers efficiency improvements at the connection stage.

UQD Universal Quick‑Disconnect Coupling Constructed with SUS316L main body and EPDM sealing gaskets. It enables effortless plug‑and‑unplug operation with minimal fluid spillage. It supports rapid system assembly and disassembly for maintenance, drastically cutting downtime for overhaul.

UQDB Universal Blind‑Mate Quick‑Disconnect Coupling Optimized for blind‑mounting inside server racks. Connection can be completed without precise alignment, catering to automated deployment and maintenance requirements for high‑density rack environments.

System‑Level Solution for Demanding Operating Requirements

As a complete system‑level offering, Letone Technology's liquid‑cooling pipeline solution goes beyond qualified performance of individual components, and creates customer value across the full product lifecycle.

• Full‑loop cleanliness & compatibility: A unified inner‑rubber formula is adopted across the entire product portfolio, ensuring consistent medium compatibility throughout the fluid loop. It prevents precipitate risks caused by material mismatches among different components and sustains long‑term coolant cleanliness.
• All‑scenario flame‑retardant safety: Both hose outer rubber and connector sealing gaskets comply with stringent data‑center safety requirements. The whole solution is certified to UL94 V‑0 flame‑retardant standard, building a full‑chain fire‑safety barrier.
• Broad environmental adaptability: Specially‑formulated synthetic outer rubber delivers excellent anti‑oxidation, weather‑resistance and UV‑resistance. It works well for constant‑temperature domestic computer rooms, and copes with complex temperature‑humidity conditions and outdoor operating environments for overseas projects, maintaining consistent performance for cross‑regional deployments.
• Responsive customized services: Custom optimization is available for hose structure, connector types and length specifications to quickly match connection requirements of equipment from diverse manufacturers. Localized manufacturing guarantees fast lead times, addressing common industry pain points of long delivery cycles and limited customization options associated with imported products.

Recently, Letone Technology's liquid‑cooling pipeline products have been successfully deployed in the liquid‑cooling system verification project of a premium overseas data center operated by a leading Southeast Asian cloud vendor. Technical services were provided by S Company, a professional domestic third‑party testing institute, to comprehensively verify the adaptability of domestic pipeline products in high‑end overseas scenarios.

Covering precise end‑point jump connections and long‑distance main‑line fluid transmission, from domestic computing hubs to overseas core nodes, Letone Technology keeps centering on ultra‑high‑pressure fluid technology and continuously refines its full‑scenario liquid‑cooling pipeline solutions. Backed by local manufacturing bases, full‑chain quality control systems and responsive technical support, Letone delivers highly reliable, well‑adapted and cost‑effective domestic solutions.
