Wind Tunnels
Wind Tunnels
Wind tunnels for electronics testing are benchtop laboratory instruments designed to simulate controlled airflow conditions for evaluating the thermal performance of electronic components, printed circuit boards (PCBs), heatsinks, and cooling systems. Unlike large aerospace wind tunnels, these compact systems generate precisely controlled laminar airflow across a test section, allowing engineers to characterize component thermal resistance, measure junction temperatures, and validate cooling designs under realistic operating conditions. They are indispensable tools in electronics thermal management research and product development across the semiconductor, telecommunications, and computing industries.
Advanced Thermal Solutions (ATS) manufactures both open-loop and closed-loop benchtop wind tunnels. Open-loop designs draw ambient air through the test section for straightforward thermal screening, while closed-loop systems recirculate air for improved temperature control and extended test cycles. Specialized PCIe variants accommodate full-length expansion cards, enabling thermal validation of GPUs, FPGAs, and high-power compute modules under airflow conditions representative of server and workstation chassis environments.
Typical Applications
- Thermal resistance characterization of heatsinks, heat pipes, vapor chambers, and thermal interface materials in electronics cooling R&D
- PCB-level airflow analysis and component junction temperature measurement under controlled velocity conditions
- Cooling system validation for servers, telecom equipment, and embedded computing platforms prior to product release
- PCIe card thermal testing for GPU, FPGA, and high-power expansion modules in data center and workstation applications
- University research and education in fluid dynamics, heat transfer, and electronics thermal management engineering
