Wind Tunnel Exceeds 20,000 CFM Flow Rates
April 4, 2006, Woburn, MA: Lytron announced today the addition of a 21,000 cubic feet per minute (CFM) wind tunnel and blower to its Woburn, Massachusetts facility. The new wind tunnel, which is one of two at the facility, was designed to test heat exchangers for various high tech applications, including military and aerospace, medical and industrial lasers, medical imaging, analytical instrumentation, power electronics, semiconductor equipment, machine tools, and telecommunications.
The wind tunnel, which has flow rates ranging from 150 CFM to 21,000 CFM, is equipped with a Variable Frequency Drive (VFD) to control the blower. It also has an electronically controlled damper for fine-tuning. The airside frontal area has up to a 6 ft x 6 ft (1.8 m x 1.8 m) test section capability, with minimums depending on configurations. Flow rates are measured by a 24" or a 6" Venturi Tube (a converging/diverging nozzle), both with 0.25% accuracy. The system measures pressure drop using high accuracy (within 0.025% of measurement) capacitive-type pressure transducers.
To test liquid-to-air heat exchanger systems, a 40 kW, hot oil pump stand is used in conjunction with the wind tunnel. It is capable of pumping up to 125 GPM. The pump stand uses solid-state proportional control to supply highly accurate and stable oil temperatures. The wind tunnel and hot oil pump stand systems can be operated together or independently for customized testing capabilities.
"The new wind tunnel allows Lytron to better serve its customers by extending its test capabilities", says Charles Carswell, president and CEO of Lytron. "Our focus is on product innovation and quality, as well as customer support. We're investing heavily in engineering resources to provide efficient and reliable liquid cooling components and systems."
In conjunction with the wind tunnel and hot oil stand, Lytron has expanded its data recording capabilities with the addition of a National Instruments™ data acquisition system and high accuracy sensor system. All physical parameters in wind tunnel testing are obtained and recorded with 16-bit resolution using a 32-channel chassis with on-board multiplexer. Custom programs calculate product performance and can detect the condition of a test set-up in minutes. The data acquisition system and software are currently being used to test many Lytron standard and custom products including heat exchangers, cold plates, and chillers for OEMs in the U.S. and internationally. Tours of the Lytron facility, factory, and/or wind tunnel test laboratory are available upon request. For more information or to schedule a tour, call (781) 933-7300.
Founded in 1958, Lytron designs and manufactures cold plates, chillers, cooling systems, and heat exchangers. Lytron primarily partners with OEMs that demand high performance, customized solutions with requirements between 50 and 50,000 pieces a year. Last year, Lytron shipped over 600 unique custom parts to OEMs. The company also offers over 100 standard products ideal for prototyping as well as end-user applications.
