Features
High Thermal Conductivity
Phase-change heat transfer delivers much higher efficiency than solid copper.
Even Heat Distribution
Reduces hot spots and keeps temperatures stable.
Small and Lightweight
High performance in a compact size, ideal for tight spaces.
Corrosion Resistant
Pure copper ensures long-term stability in harsh conditions.
Easy to Shape
Can be bent or flattened for flexible design integration.
Wide Temperature Use
Works across a broad temperature range with suitable fluids.
Quality Control
Raw Material Control
Use oxygen-free or high-purity copper. Check composition, dimensions, and surface defects to ensure stable performance.
Wick Structure Control
Strictly control powder size, groove depth, or mesh density. Inspect uniformity and porosity for reliable capillary action.
Cleaning Process
Ultrasonic cleaning and vacuum degreasing remove oil, particles, and moisture to maintain heat transfer efficiency.
Working Fluid Filling
Precisely control fluid type and charge volume. Weight checks ensure accurate filling and prevent dry-out or flooding.
Vacuum Sealing and Leak Test
Seal under high vacuum. Each heat pipe is leak-tested to ensure long-term airtightness.
Thermal Performance Testing
Test heat capacity, thermal resistance, and temperature uniformity under operating conditions.
Forming and Strength Inspection
Inspect bent or flattened pipes for deformation, wall thinning, and wick damage.
Aging and Reliability Test
Thermal cycling verifies long-term stability and performance consistency.
Pipe Dimensions
Custom diameter, wall thickness, and length for different heat loads and spaces.
Wick Structure Selection
Sintered, grooved, or mesh wicks selected for required capillary performance.
Working Fluid and Filling Ratio
Fluid type and charge optimized for operating temperature and orientation.
Shape and Forming Design
Supports bending, flattening, and complex routing without performance loss.
End Structure and Sealing
Custom end designs improve thermal contact and sealing reliability.
Surface Treatment
Natural copper, nickel plating, or protective coatings available.
Thermal Performance Targets
Designed to meet specified heat capacity and thermal resistance.
How to Maintain
Proper Handling
Avoid excessive bending, twisting, or force near sealed ends.
Protect Sealed Ends
Do not cut, drill, or modify; seal damage causes fluid leakage.
Maintain Surface Cleanliness
Keep surfaces clean and free of oil, dust, or oxidation.
Thermal Interface Check
Inspect TIM; replace aged or dried materials to ensure good contact.
Temperature Control
Operate within design range to protect fluid and wick structure.
Avoid Chemicals
Keep away from corrosive acids or alkalis; use treated surfaces if needed.
Periodic Inspection
Check for dents, deformation, discoloration, or oxidation.
Replacement Policy
Replace damaged or degraded heat pipes; they are non-repairable.
