Rittal Corporation, a manufacturer of industrial and information technology enclosures, racks and accessories, has released the Rittal Liquid Cooling Package Direct (LCP DX), a cooling system for small- and medium-sized IT installations where “climate control with air/water heat exchangers or cold water would be too costly.” Available in two versions suitable for rack-based or … [Read more...]
CPU Cooler with Active Noise Cancellation Technology
Cooling solutions provider Noctua demonstrated prototypes of a microprocessor cooler with active noise cancellation (ANC) technology at Computex Taipei 2013 in Taiwan earlier this month. The cooler, a joint project between Noctua and noise reduction technology developer RotoSub, is expected to be released mid-2014. “While the 120mm ANC fan for watercooling radiators is still … [Read more...]
Tiny Thermometer Measures Atomic-Scale Heat Dissipation
A breakthrough demonstration of heat dissipation at the atomic scale by an international research team could help scientists overcome major technological hurdles in the development of smaller, more powerful electronics. Heat—produced when a current passes through a conductive material—remains a major obstacle in the continuing development of smaller, faster, more reliable … [Read more...]
Two-Phase Flow Control of On-Chip Two-Phase Cooling Systems Developed for Blade Servers of Data Centers
Server manufacturers and data center managers are showing a greater concern regarding the energy efficiency and cooling of the new generation of servers for data centers. With very large data centers exceeding 100 000 servers, some even consuming more than 50 MW [1] to operate, this electrical energy is directly converted to heat and then simply “wasted” as it is dissipated … [Read more...]
Thermal Facts and Fairy Tales: A System Perspective for Electronics Cooling
A friend of mine who was an aspiring plumber once stated that all you need to know to be a plumber is that you get paid on Friday and that waste flows downhill. Maybe there is a similar analogy for thermal engineers that regardless of when we get paid, thermal energy will flow in the direction of decreasing temperature. The direction of heat flow with respect to temperature … [Read more...]
