SS316 Server Liquid Cooling Bellows

SS316 Server Liquid Cooling Bellows: Its core advantage lies in ultimate leak prevention and fault resistance. Seamless forming combined with the corrosion resistance of SS316 material eliminates coolant leaks caused by pipe corrosion or seal failure—such leaks could render expensive IT equipment unusable and disrupt core business operations. This product delivers 10-20 years of leak-free, fault-free operation (matching data center lifecycles), significantly reducing operational risks and downtime losses for liquid-cooled servers. Simultaneously, its high-purity materials prevent coolant contamination, ensuring stable thermal-physical properties of the cooling medium. This maintains consistent heat dissipation efficiency, stabilizes server chip temperatures, and prevents performance degradation and hardware wear caused by insufficient cooling.

I. Core Features

The SS316 server liquid cooling bellows is a precision transmission component specifically engineered for data center server liquid cooling systems. Combining the material properties of SS316 stainless steel with the structural advantages of bellows, it precisely meets the core requirements of servers for high load capacity, high cleanliness, and long-term continuous operation. Key features include:

1. Material Properties: Corrosion-Resistant, High Purity, and Compatible with Liquid Cooling Media

Constructed from SS316 stainless steel (containing 2%-3% molybdenum), it differs from standard 304 stainless steel. Its low-carbon design (≤0.03%) effectively suppresses “sensitization” during welding, preventing intergranular corrosion and ensuring welded joints maintain equivalent corrosion resistance to the base material. The inherently chemically inert material features smooth inner walls free of scale and residues, meeting the stringent cleanliness requirements for server liquid cooling systems. This prevents micro-particle blockages in cold plate microchannels (hydraulic diameters often <1mm). It is compatible with mainstream data center coolants, including ethylene glycol solutions (25±5% concentration) and fluorinated fluids, without reacting with coolants or their corrosion inhibitors/biocides. No metal ions or contaminants leach out.

2. Structural Design: Flexible Adaptability, Vibration Damping, Noise Reduction, and Reliable Sealing

Features a multi-layer convoluted corrugated tube structure precision-formed via hydraulic forming. Offers superior axial, lateral, and angular compensation capabilities to flexibly accommodate complex internal server cabling. Compensates for installation deviations between piping, cold plates, and CDU (Cold Distribution Units) while absorbing mechanical vibrations from server operation and pump activity, reducing stress impacts on connection interfaces from vibration transmission. Seamless forming eliminates redundant weld points, minimizing potential leakage failure points. Paired with a specialized sealing structure, it ensures long-term leak-free operation. Designed for hot-swap maintenance scenarios, it withstands repeated mechanical stress from insertion/removal without compromising seal integrity.

3. Performance Parameters: Adaptable to Extreme Conditions, High Stability

Wide temperature tolerance, operating stably from -40°C (transport/standby low-temperature environments) to 70°C (operational high-temperature environments). Select models withstand extreme temperatures from -200°C to 500°C, fully covering server liquid cooling system requirements. Maintains structural integrity and mechanical stability at coolant supply temperatures (40-55°C). Superior pressure resistance: Rated working pressure meets standard server liquid cooling system requirements of 0.1-0.3MPa. Certain specifications withstand 0.6-25bar pressure. Passes 3x maximum working pressure testing with no leakage or permanent deformation. High tensile strength, resistant to aging and cracking, suitable for high-load thermal management demands of high-power servers (e.g., NVIDIA GB300).

4. Precision Dimensions: Optimized for Compact Server Spaces

Manufactured using advanced CNC machining with precise dimensional tolerances (±0.1mm), it offers small-diameter specifications like DN4, DN6, DN8, and DN10. Designed for compact server installation spaces, it features lightweight construction and a compact structure that minimizes server rack load. Easy to install, disassemble, and maintain, it supports customized production based on server models and liquid cooling system layouts.
