Power conversion efficiency has been the standard means of comparing the performance of the power converter as it provides a simple and direct way to evaluate a given converter's performance while evaluating the heat sinking and cooling requirements at the same time. The efficiency tool works very well when we have established standard input and output voltages that are more or less fixed in value...
The power density in electronic equipment and thus the overall power consumption are increasing continuously. This is especially true for the new technologies in telecommunication systems like the UMTS base stations, where full control over thermal management at any point inside the enclosures is mandatory. Since an improved cooling normally is based on higher air flow rates, acoustic noise becomes...
High-density servers present a significant cooling challenge. Vendors are now designing servers that can demand over 20 kW of cooling per rack. With most data centers designed to cool an average of no more than 2 kW per rack, innovative strategies must be used for proper cooling of high-density equipment. This paper provides a ten-step approach for increasing cooling efficiency, cooling capacity,...
