Leak-Free Liquid-Cooling Flexible Bellows

 

1. Zero-Leak Hermetic Sealing (Core Advantage)

  • Fully welded seamless metal or integrated fluoropolymer structure eliminates rubber gaskets that degrade, swell or crack over thermal cycles.
  • Passes strict helium mass spectrometer leak testing, achieving ultra-low leak rates to prevent coolant loss in closed liquid cooling loops.
  • Avoids catastrophic risks of dielectric fluid/glycol leakage, such as server short circuits, board corrosion and data center shutdowns.

2. Multi-Directional Flexibility & Layout Adaptability

  • Corrugated structure delivers axial, lateral and angular displacement, fitting narrow, complex rack layouts between cold plates, CDU and pumps.
  • Small minimum bend radius enables neat routing inside dense AI server, high-performance computing and battery cooling cabinets without pipe tension.
  • Compensates installation misalignment between rigid pipework and heat sinks, reducing connection stress.

3. Thermal Expansion & Contraction Compensation

  • Absorbs thermal elongation and shrinkage of piping under frequent temperature swings (-60℃ ~ 120℃ typical liquid cooling range).
  • Relieves thermal stress at joint points, preventing pipe fatigue, fitting loosening and hidden leakage risks from cyclic heating/cooling.
  • Stabilizes system pressure spikes caused by coolant volume change in long hyperscale cooling pipelines.

4. Superior Vibration Isolation

  • Dampens pump vibration and fluid pressure pulsation by up to 90%, blocking vibration transmission to sensitive CPUs, GPUs and memory modules.
  • Extends service life of precision electronic components and reduces metal fatigue failure of rigid pipe connections.
  • Lowers overall system noise in data center and immersion cooling environments.

5. Excellent Chemical & Corrosion Resistance

  • Options of 316L/321 stainless steel, Inconel, PTFE/FEP compatible with glycol, fluorinated dielectric coolants and industrial thermal fluids.
  • Material is chemically inert, no ion precipitation or contamination of high-purity coolant, maintaining stable cooling loop fluid quality.
  • Resists rust, salt spray and coolant oxidation, suitable for coastal, industrial and long-running indoor cooling systems.

6. Stable Hydraulic Performance & Low Flow Resistance

  • Smooth inner wall minimizes pressure drop, supporting large coolant flow rates and improving overall cooling energy efficiency (lower PUE).
  • Reinforced braided outer layer boosts burst pressure resistance, offering ample safety margin under continuous system working pressureAlibaba.co….
  • Consistent flow performance after thousands of bending and thermal cycles, no inner wall deformation blocking circulation.

7. Long Service Life & Low Maintenance Cost

  • No aging rubber seals to replace; maintenance-free full lifecycle matching liquid cooling systems.
  • Outstanding bending fatigue resistance, withstands repeated flex and temperature cycling without cracking.
  • Cuts downtime, inspection labor and spare part replacement costs for large-scale data center deployments.

8. Wide Temperature & Safety Compatibility

  • Operates reliably under cryogenic cold to high-temperature cooling conditions.
  • Fluoropolymer versions meet UL94 V-0 flame retardant standards, low smoke and non-toxic combustion for IT room safety.
  • Anti-condensation optional outer insulation sleeve avoids cabinet dew, protecting circuit boards from moisture damage.

9. Universal Connection Compatibility

  • Supports quick-disconnect couplings, welding, flange and threaded ends for fast assembly and modular server maintenance.
  • Compatible with standard cold plate, manifold and CDU interfaces, easy to integrate into new or upgraded liquid cooling projects.
