Introduction The main topic of the article is how to cope with the increasing need for standardization of thermal characterization of LEDs (Light Emitting Diodes) and LED-based products (see Fig.1 showing a typical LED package). The LED-business is growing much faster than analysts predicted five years ago. Unfortunately, the progress in thermal characterization has not kept … [Read more...]
Numerical Simulation of Complex Submicron Devices
Introduction Significant increases in temperature are believed to contribute to losses in reliability and performance, and can present serious complications to thermal management. The net thermal effect depends on a combination of factors related to the feature size, power densities, and material properties. In semiconductor devices, higher heat flux densities can result from … [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...]
