The pace of development in the electronics and telecommunication fields has been accelerating in all aspects of the business. For example, electronics/telecommunications equipment has traditionally been housed in large buildings, smaller buildings (sheds) and outdoor cabinets. The introduction of the electronics to the outside has imposed serious constraints on enclosure design … [Read more...]
The Junction-to-Case Thermal Resistance: A One-Dimensional Underachiever in a Three-dimensional, Conjugate Heat Transfer World
INTRODUCTION As integrated circuits were becoming more widespread in the 1980’s, most of the developmental problems had to do the with electrical operation of the devices and not so much on cooling them, due to low power levels. It was the electrical engineers who did the functional testing, an activity that ultimately expanded to include thermal testing. Even the thermal … [Read more...]
New Synthetic Dielectric Coolants Deviate From Traditional Petroleum-based Dielectric Oils
Image Caption: A capacitor failure on a GPU board was caused from oil absorption through the capacitor’s rubber seats while emerged in white oil. As higher clock frequencies and smaller transistor dimensions continue to increase the power density of high-performance computing technologies, such as CPUs, GPUs, FPGAs, Laser Diodes, and Optical electronics, advances in thermal … [Read more...]
Introducing Our New Technical Editor – In the End, Entropy Always Wins… But Not Yet!
Greetings to all Electronics Cooling’s loyal readership and visitors, I have recently had the privilege of joining the Electronics Cooling team alongside the incredible Editorial Board and ITEM Media. My goal as part of the team is to help the experts on the Editorial Board and ITEM Media production staff to continue driving Electronics Cooling to add the most value to its … [Read more...]
How Vapor-Compression Cooling Works
Vapor-compression cooling can be found in virtually any home, such as in air conditioners that remove heat from our homes and in refrigerators that store our food. The history of vapor-compression goes back to 1805 where Oliver Evans, an American inventor, described a closed vapor-compression refrigeration cycle for producing ice. The first working vapor-compression … [Read more...]
