Compact thermal modeling in electronics design Sarang Shidore Flomerics Inc Introduction The challenge of accurately predicting junction temperatures of IC components in system-level CFD simulations has engaged the engineering community for a number of years. The primary challenge has been that near-exact physical models of such components (known as detailed thermal models, or … [Read more...]
Using a simple air recirculation model to explore computer rack cooling
Figure 1. Schematic diagram of simple computer rack air recirculation model. Figure 2. Schematic diagram of computer rack air recirculation model with heat exchanger in rear of computer rack. In an article in the November 2006 issue of ElectronicsCooling it was noted that “advances in computer clusters have resulted in the introduction of higher density server … [Read more...]
Microscale heat transfer
Advances in microfabrication processes have led to a continuous miniaturization of Field Effect Transistors (FET) that contain semiconductor (e.g., silicon), insulator (e.g., silicon dioxide), and metallic (e.g., copper interconnects) layers only a few nanometers thick. Ever increasing demand for faster microprocessors and the continuous trend to pack more transistors on a … [Read more...]
Effect Of Improved Thermoelectric Zts On Electronic Module Coolability
In recent years there has been a growing interest in the application of thermoelectrics to electronics cooling. Attention has been focused on thermoelectric cooling both as a possible means to enhance module cooling and to address the chip hot spot problem. Effort has been directed towards the development of new bulk materials and thin film micro-coolers. The usefulness of … [Read more...]
Liquid Cooling Of A High-Density Computer Cluster
Introduction Recent advances in computer clusters have resulted in the introduction of higher density server equipment that consumes significant amounts of electrical power and produces an extraordinary amount of heat. Due to this latter attribute, which has alarming consequences with regard to thermal management, the installation of modern computer clusters will require … [Read more...]
