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...]

What! All that just for that? The bonkers world of CPU cooling.
My colleague Ed and I were marvelling the other day at the CPU cooling unit from one of our training desktop PCs undergoing a repair. "What, all that just for that!?". The CPU itself was but a small square wafer compared to the behemoth that was the ducted fan and heatsink with integral heatpipes mounted on top of it. Whereas transistor sizes are measured in nanometres cooling … [Read more...]
