Boosting Aero-Engine Performance with Spiral Heat Exchangers and HeatX

Cooling hot-end components in aero-engines is a critical challenge affecting performance, lifespan, and reliability. To address this, researchers have explored using supercritical aviation kerosene as a heat sink in a spiral heat exchanger to cool the air in these high-performance systems. The results are promising, showing enhanced heat transfer performance thanks to innovative designs. Moreover, HeatX, an advanced surface treatment, can further elevate the efficiency and durability of these systems by protecting against wear and corrosion.

The Role of Spiral Heat Exchangers in Heat Management

Spiral heat exchangers stand out for efficiently managing heat transfer in challenging environments. Numerical simulations using Fluent software highlighted how spiral tubes induce a secondary flow effect, which greatly enhances heat transfer capabilities. As the turning angle of the spiral tube increases, the secondary flow effect strengthens, boosting thermal performance.

Additionally, the study introduced a diaphragm-enhanced spiral heat exchanger, which further improved heat transfer efficiency. This optimized design increased the Performance Evaluation Criterion (PEC) index of the air side by more than 20%, showcasing the potential for advanced engineering solutions in the aerospace industry.

The Role of HeatX in Enhancing Efficiency and Durability

While the design improvements of spiral heat exchangers are groundbreaking, their long-term performance and reliability depend on robust protection. Enter HeatX, an innovative surface treatment designed to:

• Enhance Durability: Protects against corrosion, scaling, and wear, especially in high-stress environments.
• Improve Efficiency: Maintains optimal heat transfer performance by preventing surface degradation.
• Extend Lifespan: Reduces maintenance requirements, cutting operational costs and downtime.

When applied to spiral heat exchangers, HeatX boosts efficiency and ensures that these systems withstand the rigors of aviation environments.

A Winning Combination for Aero-Engine Cooling

As aero-engines face increasing performance demands, effective cooling solutions are more important than ever. The combination of spiral heat exchanger technology and HeatX surface treatment offers a powerful solution. Together, they provide:

• Superior thermal efficiency for hot-end components.
• Long-lasting protection against operational stress.
