Minimizing Thermocouple Errors in Electronics Thermal Characterization
Thermocouples are a common, inexpensive tool for performing thermal characterizations on systems, PCBs, and individual components. Although using thermocouples appear to be simple, errors frequently occur due to improper calibration and other factors, creating inaccurate temperature readings. This article provides guidelines in order to help improve the accuracy of temperature measurement when using thermocouples.
Salient Features of a Piezoelectric Fan and Their Deployment in Electronic Systems
Piezoelectricity has been around for over a century, but until recently was not applicable to electronics. Because of the decreasing size of components and increased power demand in advancing technologies, piezoelectric fans are now being used in electronics because of their lower acoustic noise, space requirements, power consumption and reliability. This article discusses the benefits of piezoelectric fans and research on its future implementation.
Technical Note: Requirements of Accurate Measurement with RTD
In this new section, Qpedia reviews fundamental thermal engineering principles, calculations and equations needed for the successful cooling of electronics This issue discusses how to accurately measure temperature using RTDs.
Industry Developments: Vehicle Climate Control Systems
Automobiles must operate in a wide variety of environmental conditions, from very high to very low ambient temperatures with strong solar radiation. Typically cars are driven over open terrain, which creates a thermal challenge in order to insure that its interior quickly and quietly maintains the desired temperature regardless of the outside weather conditions. In this issue our spotlight is on devices used for thermoelectric cooling.
Technology Review: Thermoelectric Cooling Devices
Qpedia reviews innovative technologies developed for electronics cooling applications. This section presents selected patents that were awarded to developers around the world to address cooling challenges. In this issue our spotlight is on thermal management systems for LED lighting.
