Part II can be found here. There is an increasing need for calculating integrated circuit temperatures during conditions of changing chip power. Varying computer workloads and the implementation of power-saving strategies are leading to greater variability in chip power levels than in the past. As reliability requirements get more stringent there are growing concerns about the … [Read more...]
Efficient Electro-Thermal Simulation of Power Semiconductor Devices via Model Order Reduction
Thermal management is an increasingly important consideration in the development of power electronic systems. Electro-thermal simulation is required at the system level in order to ensure under realistic loads the fulfillment of thermal requirements, which strongly influence the performance, reliability and efficiency. A significant modeling issue is to obtain a compact but … [Read more...]
The Increasing Challenge of Data Center Design and Management: Is CFD a Must?
Data centers have been cooled for many years by delivering cool air to the IT equipment via the room. One of the key advantages of this approach is the flexibility that it provides the owner/operator in terms of equipment deployment. In principle all that is necessary is to determine the maximum power consumption of the equipment and provide an equivalent amount of cooling to … [Read more...]
Energy Reduction and Performance Maximization through Improved Cooling
The International Technology Roadmap for Semiconductors [1] predicts high performance processor power density to more than double by the year 2024, while during the same time allowable junction temperature will decrease from 90oC to 70oC, reducing the junction-to-ambient temperature difference to nearly half. This combined challenge to cooling will require the total thermal … [Read more...]
Direct Current-Powered Data Center Module
ABB and IO have agreed to partner in the development of a new data center module based on direct current (DC) power to meet increasing demand for DC data centers. DC-powered technology is being increasingly adopted for electrical distribution in data centers as it reduces power conversion losses and is 10 to 20 percent more energy efficient than traditional alternating current … [Read more...]
