ABSTRACT Cooling fan noise is a system property determined as much by thermal and mechanical design and fan selection as by a fan’s acoustical design. While even the quietest fan can be used in a noisy manner, a significant fraction of unpleasant surprises can be avoided. NOMENCLATURE C Numerical constant D … [Read more...]
Some New Cooling Ideas are Needed Here
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...]
Heat Exchangers Cool Electrical Enclosures, Keep Dust Out
Industrial air conditioner units are typically the solution for cooling sealed enclosures. What designers sometimes fail to consider, however, is that a cooler ambient environment could be used to help cool warmer electrical enclosure, particularly when there is a temperature difference between the internal target temperature and the surrounding temperature of ∆T≥10°C. … [Read more...]
