Rosenberg has recently expanded its high-efficiency E-Series backward-curved impellers to now include sizes from 12.4 to 22 inches with either AC or EC motors. The unique airfoil blade impeller increases energy efficiency by up to 4% and reduces noise by 3 to 5 dB(A). Recommended for computer room air conditioning and air handling (CRAC/CRAH), or energy recovery. … [Read more...]
New PWM Controller for Fans Released
SANYO DENKI has recently released their “San Ace PWM controller”, which controls fan speed through PWM. This contributes to reduced system power consumption and the fan noise. Up to four PWM-input fans can be connected to each controller, without requiring a costly function generator. The controller can be powered by the fan power supply at rated voltages of 12, 24, and 48 … [Read more...]
How to Choose the Right Solution for Effective Heat Management
(June 3, 2016) Because electronics have shrunk significantly in recent years, the solutions to cool them must be adjusted. Electropages.com suggests “a case-specific analysis must be performed as each application is subject to different circumstances,” to determine the right strategy for cooling electronics. This analysis is called “CFD analysis,” or computational fluid … [Read more...]
Laser Storage in Data Centers Could Mean Less Heating
(June 3, 2016) Davide Bossini from the University of Tokyo has found a possible solution to control the demand for smaller, faster, devices to store, manage, and process data in data centers without compromising cooling. “A way to store information in a particularly tiny area is by taking advantage of the fact that individual electrons possess magnetization, which is called … [Read more...]
Custom Liquid Cooling System for Data Centers
(June 2, 2016) “A special unit within Dell that makes custom tech for operators of the world’s largest data centers, has designed a water-based system for cooling custom server chips it developed” for eBay with Intel Corp. and eBay itself, reported DataCenterKnowledge.com. The custom liquid cooling system follows an atypical design, according to DataCenterKnowledge, “It brings … [Read more...]
