Overview Sometimes, regardless of how carefully we conduct testing to gather data, we end up with results that just seem wrong. This could be a sign that we have stumbled upon an earth-shattering breakthrough that will change the world’s understanding of fundamental physics1 …. or, it’s possible that a mistake in the testing led to bad data. This column will discuss a few … [Read more...]
Cooling the Heat: A Journey Through Data Center Cooling Systems
Introduction Data centers play a vital role in the digital era by facilitating the storage, processing and distribution of vast amounts of information. As our world becomes more interconnected the demand for data centers keeps rising, which calls for efficient and sustainable cooling methods. It has been noticed that 42% of a data centers energy consumption is devoted to … [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 … [Read more...]
Advanced Cooling System for Modular Electronics Thermal Management
Introduction Modern electronics are rapidly evolving to meet high-computing needs while shrinking in size resulting in large heat fluxes that must be removed for safe operation. Figure 1 shows a schematic of a generic electronics cooling system with representative heat transfer pathway from a chip (heat source) to a cold plate (heat sink) via heat spreaders and card retainers … [Read more...]
Calculating Thermal Design Power for Mobile Consumer Electronics – Part 2
Overview Thermal Design Power (TDP) is a term commonly used in the thermal management of consumer electronics. While the usage of this terminology may vary across the industry, it commonly refers to the amount of power that a device may dissipate indefinitely, in a given thermal environment, without exceeding the temperature limits of the device. The TDP for a consumer … [Read more...]
