Challenges in the Defense and Aviation Sectors and the Value of Liquid-Cooled Connectors
Challenges Unique to the Defense and Aviation Sectors
- As the power density of airborne and shipborne electronic equipment continues to rise (e.g., laser weapons and electronic warfare systems), air cooling is no longer sufficient to meet heat dissipation requirements.
- The combat platform operates in extreme environments (high altitude: -55°C; desert: 70°C; shipboard salt fog; deep-sea high pressure)
- High-Impact and Broadband Random Vibrations (Shell Firing, Aircraft Landing Impacts, Helicopter Rotor Vibrations)
- The system requires extremely high reliability; a single leak could result in mission failure or platform damage.
- There is an urgent need to reduce equipment weight; traditional metal fittings are too heavy, which affects payload and range.
- In wartime or field conditions, modules need to be replaced quickly, and traditional rigid pipe connections are inefficient.
- Electromagnetic Compatibility and Security Requirements (Complex Shipboard/Airborne Electromagnetic Environment)
Liquid-Cooled Fitting Solutions
- High-power-density liquid-cooled heat dissipation: Supports a single-channel flow rate of over 20 L/min, with a pressure drop-optimized design to meet the heat dissipation requirements of heat loads in the hundreds of kilowatts.
- All-environment adaptability: Operating temperature range of -55°C to 125°C; salt spray resistance of ≥1,000 hours; deep-sea version with a pressure resistance of ≥30 MPa.
- Extremely High Vibration and Shock Resistance: Passed the MIL-STD-810 (U.S. Military Standard) and GJB 150 (Chinese Military Standard) series of tests, with shock resistance of ≥100g and vibration resistance of ≥40g RMS.
- Multi-redundant sealing architecture: three-tier protection consisting of a primary seal, secondary seal, and emergency seal; helium mass spectrometer leak rate ≤ 1×10⁻⁶ Pa·m³/s; design life ≥ 20 years.
- Ultra-lightweight solution: Aerospace-grade aluminum alloy/titanium alloy body + specialty engineering plastics, resulting in a weight reduction of over 60% compared to conventional stainless steel solutions.
- Blind-mate floating design + error-proofing coding: Supports ±5 mm positional compensation, allows for quick one-handed insertion and removal, and ensures zero leakage upon disconnection, making it suitable for battlefield emergency repair scenarios.
- Electromagnetic Shielding Design: Optional conductive gasket + grounding path; shielding effectiveness ≥60 dB; meets the electromagnetic compatibility requirements of GJB 151B.
Key Product Advantages
Full Lifecycle Reliability Verification
Through rigorous testing, including accelerated life testing (ALT), temperature shock cycling (-55°C to 125°C, 5,000 cycles), random vibration (48 hours continuous), and salt spray corrosion (1,000 hours), the product has been verified to have a service life of ≥20 years.
Protection Against Multiple Failure Modes
Features a built-in anti-loosening locking mechanism, a secondary locking mechanism, and an automatic dust- and debris-proof cover to maintain a complete seal even under extreme operating conditions.
Material-Level Compatibility
Fully compatible with military-grade cooling media (Coolant No. 65, polyalphaolefins (PAO), ethylene glycol solutions, deionized water, fluorinated fluids, etc.), with no material degradation or leaching.
Traceability and Standardization
Each connector has a unique serial number, enabling traceability throughout its entire lifecycle; the connector design complies with MIL-C and GJB standards and is compatible with existing equipment.
