In the data center, power and cooling costs more than the it equipment it supports
Historically, the cost of energy and the cost of the data center power and cooling infrastructure have not been on the radar for most Chief Financial Officers (CFO) and Chief Information Officers (CIO) and have not been considered in TCO (Total Cost of Ownership) models. As a result, almost all of the focus has been on driving down the cost of IT equipment in the data center. … [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...]
Thermal Challenges In LED Cooling
Introduction During the last ten years, developments in LED semiconductors have led to an important change in LED applications from that of luminous indicator to that of illuminator. With LEDs now advancing into several lighting fields, LEDs have become one of the standard methods of producing light, joining more traditional sources such as incandescent, fluorescent and … [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...]
