As far as history goes, the field of electronics cooling does not have a very long past. A rather quick look through my personal reference material that is strictly geared towards cooling electronics had at the earliest some US Navy documents from the 1950s [1]. Comparing the solution techniques available today to those available then shows that we have both much better tools … [Read more...]
Technical Brief: Design Considerations for High Performance Processor Liquid Cooled Cold Plates
The meteoric rise in cooling requirements of commercial computer products has been driven by an exponential increase in microprocessor performance over the last decade. The conventional way to cool microprocessors has been to utilize air to carry the heat away from the chip, and reject it to the ambient. Air cooled heat sinks are the most commonly used air-cooling devices with … [Read more...]
Calculation Corner: Transient Thermal Modeling of a High-Power IC Package, Part 1
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...]
