Medical displays specialize in reproducing clear images with high brightness and contrast while maintaining color accuracy. In recent years, there has been a push for smaller and thinner displays in the LCD and LED panel market. In addition, increased performance and image quality has increased heat generation. Therefore,...

This paper describes a new two-phase cooling heat transfer cell based on a submerged vibration-induced bubble ejection process in which small vapor bubbles attached to a solid surface are dislodged and propelled into the cooler bulk liquid. This ejection technique involves forcibly removing the attached vapor bubbles with...

The drive for smaller power supplies goes handin hand with a need for greater efficiency. There’ s a direct relationship here because the smaller the power unit, the smaller the area available for dissipating heat through conduction and convection. Through both measurement and calculation, XP Power has developed...

Power has always been a design consideration. Traditionally, though, a lower priority has been assigned to power than to most other variables (speed/performance, cost, time-to-market, risk, etc.). In today’s marketplace, however, power has become a very important component in the designer’s decision making...
