Fundamentals of Infrared Temperature Measurement
Consider the need to measure the temperature of an object without disturbing it. Contact might damage or destroy the object, change its temperature by altering its heat transfer characteristics, or cause contamination. It might be moving or inaccessible. These are prime conditions for using infrared temperature measurement.
Thermal and Hydraulic Characteristics of Two-Phase Flow in Microchannel Heat Sinks
Compared with single-phase flow in microchannels, two-phase flow can dissipate more heat while maintaining only a small temperature rise. The combined benefits of evaporation and microstructure channels make two-phase flow a promising cooling method for high power density devices.
Thermal Challenges in Automotive High Density Lithium-Ion Battery Packs
Lithium-ion batteries commonly allow double the energy density per unit volume than NiMH batteries, while occupying a lighter package due to the lower density of lithium metal. But, like most other batteries, lithium-ion variants can mechanically and chemically break down and lose their ability to store and deliver a charge at high temperatures.
Thermal Challenges of Multi-Core Processors
From the early 16 MHz 486 processors to the Intel 3.8 GHz Pentium 4, processor clock speed has been increased constantly for added performance. This has led to very high levels of power density within the CPU and many resulting consequences. Among these are increased thermal stress and the need for a large cooling system.
