Estimating Internal Air Cooling Temperature Reduction in a Closed Box Utilizing Thermoelectrically Enhanced Heat Rejection
An earlier article in this column considered the problem of cooling electronic components in a closed box [1]. In outdoor applications for example, it may be necessary to totally seal the box to prevent exposure to airborne particulates, water droplets or other sub- stances in the air that could be injurious to the electronic components. In such an application, heat picked up … [Read more...]
Thermal Management Considerations in High Power Coaxial Attenuators and Terminations
The testing and troubleshooting of high power and high frequency systems such as distributed antenna systems (DAS), base stations, and various radar applications require buffering to prevent a power overload to the testing equipment and sensitive subsystem internal circuitry. With powers as high as 60 dBm (1000 Watts), radio frequency (RF) terminations and attenuators are … [Read more...]
What a Thermoelectric Cooler is REALLY Good For…
Fairy tales… perpetual motion machines… Not all fairy tales are perpetual motion machines, but all perpetual motion machines are certainly fairy tales. Before I get into the specifics of thermoelectric coolers, however, it seems appropriate to set the stage for this particular category of fairy tales. There are two classical types of perpetual motion “machines,” called (not … [Read more...]
