Background The cooling of electronics and telecom equipment is essential to the proper operation of all applications. Removal of generated heat from these systems has been traditionally carried out via heat conduction/convection techniques. Phase Change Materials (PCMs) are a relatively new concept for the cooling of electronic systems. A PCM is used to absorb peak energy … [Read more...]

Integrated Nano-enhanced Thermal Management Techniques May Boost Photovoltaic Efficiencies
With solar energy systems growing in popularity and adoption across the globe, methods for enhancing the efficiency and power density of solar cells are a hot topic for renewable energy research labs. Essentially all photovoltaic technologies currently available suffer from reduced efficiency when operating at higher than nominal temperatures. In an attempt to reduce the … [Read more...]
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...]
