As aerospace platforms push thermal limits, custom liquid cooling plates have become essential for managing heat from avionics, power electronics, and directed-energy systems. These plates must perform under extreme conditions while meeting strict weight and certification targets. This article outlines the key engineering drivers and how we deliver them.

Key Drivers for Aerospace Cold Plates

    ● Lightweight: Aluminum alloys and thin-wall designs reduce mass without sacrificing thermal performance.

    ● High Reliability: Leak-proof joints, redundant seals, and 100% pressure testing ensure mission-critical operation.

    ● Environmental Resistance: Corrosion, vibration, thermal cycling, and altitude are addressed through material selection and coatings.

    ● Certification: Compliance with AS9100, NADCAP, and SAE/ASTM standards is mandatory.

How We Manufacture Custom Liquid Cooling Plates

We begin with thermal simulation and CFD to optimize channel geometry. From the precision equipment list, we utilize 5-axis CNC machining centers, vacuum brazing furnaces, and CMM inspection systems. Our process includes:

    1. Lightweighting: Generative design and additive manufacturing create complex internal channels with minimal mass.

    2. High Reliability: Vacuum brazing and friction stir welding produce hermetic joints. Every unit undergoes helium leak testing and burst pressure testing.

    3. Environmental Resistance: Conversion coatings, anodizing, and salt spray testing validate protection against corrosion and vibration.

    4. Certification: We maintain AS9100D and NADCAP approvals, with full traceability and documentation.

For external standards, refer to SAE International and ASTM. NASA thermal guidelines are available at NASA Technical Reports.
