Core Challenges
Cleanliness Demands
Rough surfaces shed particles — cold plate microchannels clog and cooling degrades.
Sealing Reliability
Welding quality in tight rack spaces — any leak threatens server hardware.
Uneven Distribution
Inconsistent coolant flow across nodes — hotspots reduce cooling efficiency.
Backflow Risk
Reverse flow disrupts supply — server cooling circuits face potential damage.
How We Solve Liquid Cooled Cabinet Solution Challenges
Balanced Distribution
Multi-port manifold design evenly splits coolant flow to each server node. Ensures structural strength and flow uniformity for precise rack-level thermal management.
Recommended Products:
Compact Shutoff
Integral one-piece body with inner and outer threaded connections — fits the tightest rack interiors. Low operating torque for easy manual actuation where standard valves require excessive clearance.
Recommended Products:
Compact Shutoff
Automatic Air Elimination
Float-type mechanism vents trapped air from pipeline high points without manual intervention. Built-in filter screen protects internal components for stable long-term performance.
Recommended Products:
Safe Hot-Swap Protection
Double-locking mechanism requires complete connection before opening and full closure before disconnection. Prevents accidental coolant leakage during live maintenance. Withstands high hose loads in rack deployments.

Frequently Asked Questions

How do you ensure coolant cleanliness at the rack level?

 
 

Loop filters with multi-layer sintered mesh remove particulates before coolant reaches cold plate microchannels. Electropolished piping with Ra ≤ 0.4μm finish prevents particulate shedding over the system lifetime.

What ensures even coolant distribution across server racks?

 
 

Custom distribution manifolds with multi-port design evenly split coolant flow to each server node. Factory pre-assembled and pressure-tested, delivered ready for plug-and-play installation.

How is backflow prevented in rack-level liquid cooling systems?

 
 

Integrated check valves prevent reverse flow that can disrupt coolant supply and damage server cooling circuits. Compact design fits tight cabinet interiors without additional adapters.

What welding standards apply to rack-level piping and manifolds?

 
 

All rack-level piping components are auto-welded under ISO 3834 certified processes. Every prefabricated manifold is pressure-tested before shipment, ensuring leak-proof sealing in confined cabinet spaces.
