High-Temperature Compact Heat Exchangers for Harsh Environments
Refractory Metal Designs with Embedded Sensors for Enhanced Performance and Reliability
The Challenge
High-temperature compact heat exchangers (CHXs) are vital for industries like power generation, chemical processing, and metallurgy. However, existing solutions made from nickel-based alloys face critical limitations:
Temperature Constraints: Mechanical strength deteriorates above 750°C. Corrosion Issues: May exhibit poor resistance to harsh environments, such as molten salts. Design Limitations: 2D channel configurations restrict heat transfer efficiency. Energy-Intensive Manufacturing: Current techniques, like diffusion bonding and brazing, are challenging, resource-heavy, and inefficient.These barriers prevent CHXs from reaching the temperatures needed for peak efficiency and long-term durability in extreme conditions.
How It Works
This novel technology introduces high-performance CHXs using Mo- and W-based refractory alloys combined with advanced manufacturing techniques:
Refractory Alloy Design: Mo- and W-based alloys are optimized for superior corrosion resistance (200%+ improvement over conventional materials) and mechanical strength at temperatures up to 1500°C. 3D Channel Fabrication: Customizable 3D flow channels are created using traditional additive manufacturing and digital light projection (DLP) printing, significantly improving heat transfer efficiency. Efficient Sintering Process: Electric Field Assisted Sintering (EFAS) compacts refractory alloys into robust structures, achieving a 70-90% reduction in energy consumption during manufacturing. Embedded Sensors: Aerosol Jet Printing (AJP) integrates multimodal sensors for real-time structural health monitoring (SHM), enabling advanced safety and reliability monitoring.This integrated approach allows for the fabrication of durable, high-performance CHXs designed for extreme environments.
