Introduction These columns on statistics began by describing the field of statistics as using the mathematical laws of probability to deal with data uncertainty [1]. Many statistical tools developed to apply probability do assume that data are drawn from a normally distributed population, in which the probability distribution function, f(x), of a population follows Equation … [Read more...]
Oscillating Heat Pipe Thermal Performance and Stability Limits
A heat pipe is a closed system that contains a saturated fluid. When heat is dissipated in one region of the heat pipe, liquid in that area boils or evaporates, which produces vapor that moves to another area in the heat pipe where it condenses. The condensed liquid then returns to its starting point to transport energy from the heat input region(s) to the heat output … [Read more...]
Statistics Corner: Probability
Statistical analysis is needed because data always have some degree of uncertainty; a value that we determine from a single measurement, or even set of measurements, is not necessarily going to tell us exactly what value we will determine with additional measurements. Statistical analysis uses the mathematics of probability to create tools that we can use to deal with … [Read more...]
Thermally Optimizing a High-Power PCB for Battery Powered Electronics
Introduction The growth of battery powered applications is presenting new challenges for designers of electronic motor-driven solutions. Targeting higher performance and efficiency, the power stages of these products must manage high currents while meeting strict power dissipation and size requirements. This article illustrates a thermally aware workflow with Cadence® Celsius™ … [Read more...]
Air Ionization Techniques for the Cooling of Electronic Devices: Analysis of the Different Effects of Design Features on Cooling Performance
Rotary fans have been used to cool electronic devices using forced convection applications to achieve the required heat transfer dissipation. In recent years, there has been an increasing trend to miniaturize the size and maximize the efficiency of the electronic devices which, in turn, increases heat generation. The use of rotary fan cooling conflicts with these new trends due … [Read more...]
