In the 1920s, the field of physics was in disarray. The reason was that many careful observations and experimental data could only be explained by conflicting theories; for example, some proved that light was a wave, while others provided it had a particle-like nature. Other experiments, such as those in black-body radiation or the photoelectric effect, could not be explained … [Read more...]
Thermal Management of Electronic Equipment using Phase Change Materials (PCMs)
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...]
