Quick-Connect Fitting
The Value of Radar Equipment and Liquid-Cooled Connectors
Challenges Unique to Radar Equipment
- Phased-array TR modules are highly integrated, with a thermal flux density per array exceeding 50 W/cm²; air cooling is insufficient to meet this requirement.
- Radar stations are often deployed in extreme outdoor environments (high plateaus at -45°C, salt fog on islands, and deserts at 70°C).
- Vehicle- and aircraft-mounted radars undergo continuous vibration and shock as they maneuver at high speeds with their platforms
- Ground-based radar systems require frequent disassembly and reassembly when relocating, and piping connections are inefficient and prone to damage.
- The array consists of a large number of T/R components (hundreds or thousands of channels), and the flow distribution in the parallel pipelines is uneven.
- Radar systems have a service life of 15 to 20 years, so the connectors must have the same lifespan and be maintenance-free.
- In coastal and shipboard environments, where seals are subjected to dual corrosion from salt fog and moisture, they are prone to failure.
Liquid-Cooled Fitting Solutions
- High-Density Liquid-Cooling Heat Dissipation: With an optimized flow channel design, each channel supports a flow rate of 10–30 L/min, meeting the heat dissipation requirements of kilowatt-class array panels.
- All-weather environmental adaptability: Operating temperature range of -45°C to 85°C, salt spray resistance of ≥720 hours, and IP67 protection rating (when connected).
- High Vibration Resistance Design: Passed the GJB 150/GJB 150A series vibration and shock tests, with vibration resistance of ≥20 g RMS and shock resistance of ≥50 g.
- Quick-Connect Design: Supports ±3 mm float compensation, allowing a single person to insert and remove the connector with one hand; ensures zero leakage upon disconnection; and reduces setup time between scenes by 70%.
- Low-flow-resistance, uniform-flow design: Full-bore structure + optimized valve core; flow deviation ≤ 5% when multiple units are connected in parallel, ensuring uniform array temperature.
- Long-Life Validation: Through tests such as accelerated aging, thermal shock cycling, and insertion/removal endurance, the product has been validated to have a service life of ≥15 years.
- Corrosion-resistant material system: The main body is made of 316L stainless steel or aluminum alloy with a special coating; the seals are made of fluorosilicone rubber; salt spray resistance: ≥1,000 hours.
Key Product Advantages
Compatible with a variety of radar cooling architectures
Compatible with both centralized liquid cooling (CDU distribution) and distributed liquid cooling (single-channel independent), and supports a variety of cooling media, including water, ethylene glycol solutions, and fluorinated fluids.
Modular blind-mate connectors; supports hot-swapping
The front-panel T/R modules can be plugged in and removed independently for maintenance without interrupting the operation of the entire system, significantly improving the equipment's availability.
Anti-Misinsertion Coding System
Different cooling circuits feature a mechanical anti-misinsertion design (color-coded), preventing incorrect installation that could lead to short circuits in the flow path or cooling failure.
End-to-End Traceability
Each product has a unique serial number, and records of raw materials, assembly parameters, and test data are maintained to meet military-grade quality traceability requirements.
