Introduction A thermoelectric cooler (TEC) is a solid-state refrigerator that operates on the Peltier effect. The absence of moving parts, compact size, precise temperature control ability and reliability all combine to make the TEC a unique refrigerator. TECs find application [1, 2] in many fields from simple food and beverage coolers for an afternoon picnic to extremely … [Read more...]
Challenges In Thermal Management Of Memory Modules
The Datacenter Quandary Two significant challenges facing datacenter operators today are increased power and cooling costs [1]. In a recent survey of datacenter operators, 38% of respondents said they considered both power and cooling as equally important; another 21% indicated that cooling was their major challenge; and 12% cited power consumption as a big concern [2]. Another … [Read more...]
en Route to a Greener Thermal Technology
It's no surprise. Power levels in the data center keep rising. In fact, the cost of powering the computers in the data center is beginning to exceed the cost of the computers themselves. The computer architects have responded by designing systems that use multi-core processors. These processors can use less energy to perform the same workload as their single-core brethren by … [Read more...]
Advanced Cooling Using Meso-Scale Evaporative Cold Plates
Introduction Thermal management of servers and communications equipment has become significantly more challenging over the past several years. As is well known, processor powers have increased to 150 W or more and are projected to continue to rise, despite the move to multi-core designs (and the huge investment in software that this entails) [1]. Rack-level functional density … [Read more...]
Air-Cooled, Pin Fin Coldwall Design For Operation At Altitude
Introduction Numerous thermal management techniques exist depending on the system, application, and power level. For airborne electronic systems, the most direct approach to thermal management would be to use ambient air or chilled air, provided by the aircraft, routed to and blown across the electronics. However, in some applications potential contaminants in the cooling air, … [Read more...]
