Recently, Sunon has won the iF Design Award for its “LED Lighting Ventilation Fan.” The design of the product combines ventilation fans with LED lighting. The fan delivers an ultra-high air flow and high energy efficiency as well. The LED Lighting Ventilation Fan’s DC Motor Technology “features energy saving up to 82% compared to AC motor and has an ultra-low power … [Read more...]
Industry Leading Airflow and Static Pressure Fan Introduced
Sanyo Denki has announced its new high airflow fan, the San Ace 140 9GV type, which offers the industry’s highest airflow and static pressure. It has 6.8 times the static pressure and 2 times the airflow than other DC fans on the market. “The San Ace 140 9GV type has the PWM control function, designed for controlling the rotational speed of the fan from the device side,” … [Read more...]
New Reversible Flow Fan Blows Air in Both Directions
SANYO DENKI CO., LTD. introduces the San Ace 136RF ø136 mm × 28 mm Reversible Flow Fan that blows air in both directions. “Rotational speed is controlled using an external PWM signal to deliver an appropriate rotational speed, reducing noise and saving energy,” the company said. The San Ace 136RF ø136 mm × 28 mm Reversible Flow Fan has about the same airflow and static … [Read more...]
Cooling Matters
AIR FORCE INQUIRES ABOUT THERMAL MGMT.SOLUTIONS FOR FUTURE AIRCRAFT 8/11/15 - The U.S. Air Force is looking into new thermal management techniques to cool the electronics in future fighter aircraft. “Officials of the Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio, issued a broad agency announcement Friday (BAA-AFRL-RQKP-2015-0002) for the Hybrid-Cycle … [Read more...]
Thermal Facts & Fairy Tales: Numerical Modeling without Supporting Experimentation
Peter Rodgers Fan modelling is one of the most critical aspects of the analysis of forced-air-cooled systems. Lasance [1] summarized the challenges of modeling air movers such as fans and key factors that need to be taken into consideration. Such factors include the need to model the fan hub, and to account for the swirl velocity coefficient. In addition to the above … [Read more...]
