// PRODUCTS / WIND TUNNEL HEAT EXCHANGERS

Wind Tunnel Heat Exchangers

Wind tunnel heat exchangers are critical components for aerodynamic testing facilities. Dongrun was the first Chinese domestic supplier to break the import dependency on European suppliers (2008), and has since delivered wind tunnel HX to Porsche AG, Tongji University, Tsinghua University, and AVIC. Based on FEA and CFD simulation, Dongrun designs achieve high temperature uniformity and stability, low noise, high vibration resistance, and long-term operational reliability.
