Multichannel isolated thermocouples is a system that RECOM developed for use in a test lab. We will discuss how this will be useful for others to know the advantages and disadvantages of such a system. What is a thermocouple? It is two different types of metals that are joined together. In figure 1, we have a metal that's called chromel, and another one called alumel. When … [Read more...]
Liquid Cooling Systems in Data Centers Help Companies Achieve Sustainability Goals
The millions of data centers worldwide require a significant amount of energy to function. This makes them not only very costly to operate, but also results in a substantial impact on the environment. Data Center Environmental Impact The environmental effects of all these data centers have become a growing concern to governments and the public. Industry experts are … [Read more...]
Rank Sum Tests
Introduction The previous column in this series described methods for assessing whether a set of data was normally distributed [1]. In the event that data is shown to not have a normal distribution, one might ask how to conduct a statistical analysis on it given that many statistical tests are developed on the assumption that the data are normal. For example, how can two … [Read more...]
Rapid and Accurate Analytical Model for Predicting Axial Fan Performance in Electronics Cooling
Introduction Forced air cooling remains essential for dissipating the heat generated by high-power-density devices in modern electronics [1]. Axial fans are widely used in information technology, telecommunications, automotive, and aerospace applications for air cooling. The aerodynamic performance (P-Q) curve of fans is essential for designing and optimizing air cooling … [Read more...]
