Essential Measurements for Thermal Management Engineering Course held at coolingZONE-12
Best practices for key physical measurements will be shown at the coolingZONE-12 conference in Cambridge, MA on August 27, 2012. Demos will reveal how to measure temperature, air velocity, air pressure and heat flux inside a laboratory wind tunnel.
Dr. Azar’s pre-conference short course will include a detailed introduction to measuring temperatures in electronics cooling, including the role of packaging, the impact of bad data and accounting for uncertainty. He will review the basic process of temperature measurements taken with such tools as thermocouples, thermistors, liquid crystal thermography and infrared systems.
A similarly thorough approach will be shown for measuring the fluid velocity of air in electronic systems, including the calibration and use of different types of sensors. Proper pressure measurement will be discussed, with discussion of pressure sensors and their calibration. And heat flux will be defined, with explanation of how it is measured.
Dr. Azar will also discuss the use of thermal chambers. And a hands-on test set up will demonstrate how temperature, velocity and pressure measurements taken in a wind tunnel can be used to thermally characterize heat sinks and PCBs.
Dr. Deborah Chung will present on materials for microelectronic and LED heat dissipation. Overheating is one of the biggest problems in the microelectronic and LED industries, as it limits the power, reliability, performance and further miniaturization. This problem particularly affects high-performance and high-power devices. Her talk will cover materials
Gary Kromann will present a special session on the thermal management of a 64-bit multicore communications processor, with particular focus on the design considerations for air-cooled electronic enclosures. This discussion will include the thermal management design considerations for Freescale’s next-generation QorIQ Platforms for moderate forced-air convection of electronic systems.
And, in a separate presentation by Dr. Azar, engineers will be provided with a thorough, expert look at the state of the art in thermal management, from the vacuum tube to super computers. The cooling technologies that have been developed across the electronics market sector – ranging from consumer electronics to high capacity computing to military/avionics equipment, will be presented. Dr. Azar will explain the options to exercise when selecting a cooling system while highlighting the best path for meeting the market requirements of a given electronic system.
