Introduction The growing pressure to fit as much circuitry into the smallest space possible has created new and more acute thermal problems for the design engineer. More high power components in a smaller space means higher watt densities, which lead to increased heat. As the operating temperatures of components within a design increase, their performance, stability, and life … [Read more...]
Metal Injection Molding Of Heat Sinks
Introduction New thermal management solutions are needed to provide cost-effective means of dissipating heat from future generation microelectronic devices. A relatively new process to reduce the costs of fabricating large quantities of complex components, such as heat sinks, is metal injection molding (MIM), a net-shaping process in which metal powder is mixed with a … [Read more...]
Seven Years Of Technical Data: An Overview
The first 1997 issue of ElectronicsCooling started with a Technical Data column, the first of a still continuing series of columns devoted to data that are of interest to thermal designers. In the author's opinion, it is high time to come up with an overview of all items that have been covered over the past seven years. As is obvious from the table, the majority of columns … [Read more...]
Use Of Heat Pipe Cooling Systems In The Electronics Industry
Introduction Thermal management of electronic components must solve problems connected with the limitations on the maximum chip temperature and with the requirements on the level of temperature uniformity. To cool electronic components, one can use air and liquid coolers as well as coolers constructed on the principle of the phase change heat transfer in closed space; i.e., … [Read more...]
Communication Network Power Efficiency Assessment, Limitations and Directions
Introduction Despite the slowdown in the communication industry, Internet traffic continues to grow rapidly, fueled by the explosion in data communications, mobile Internet, e-commerce, content rich applications, and multi-media services. Internet traffic has increased by approximately 80% yearly in each of the last three years, and will continue to grow at 60 - 80% annually … [Read more...]
