In the earliest days of personal computing, excess heat wasn’t a problem; any heat that was generated by the computer dissipated safely into the surrounding air. Even in the 1980s, a single fan was all that was needed to ventilate the entire inside case of the computer. However, as faster computer processors continued to develop, fans were no longer enough to maintain an ideal … [Read more...]
System Level Benefits of Augmenting Fan Cooled Servers with Localized Synthetic Jets
Raghav Mahalingam Nuventix Inc. The cooling needs of data centers and server farms have increased rapidly over the last few years due to the advent of cloud computing. The use of large banks of fans is quite common in such systems and cooling system power is a significant fraction of the operational costs. Additionally, NEBS acoustic requirements limits the use of higher speed … [Read more...]
New High-Efficiency Thermoelectric Air Conditioner
TECA Corporation has introduced the AHP-6200 family of thermoelectric air conditioners. The AHP-6200 air conditioners provide cooling performance up to 5,200 BTU/hr in the 240 VAC configurations. Each system includes TECA’s Eco-Mode temperature control design that limits active cooling when not needed, reducing total power consumption by up to 75 percent. The AHP-6200 air … [Read more...]
