COOLING IGBTS USING VAPORIZABLE DIELECTRIC FLUIDS

Dramatic increases in both power density and total power dissipation for power electronic systems, especially vehicle and airborne systems, together with demands for increased performance and speed of response, limit the application of a traditional forced convection air-cooled or a single phase liquid system. This article discusses how the newly developed Vaporizable Dielectric Fluid (VDF) cooling system, uses common dielectric refrigerants to effectively cool IGBT devices.

OPTIMAL HEAT SINK DESIGN FOR NATURAL CONVECTION IN VERTICAL ORIENTATION

Many tough-to-cool electronics applications don’t allow the use of fans, therefore heat sink solutions need to be optimized through natural convection. This article explores and compares the optimal design of traditional pin, straight fin and nontraditional heat sink designs in natural convection.

FUNDAMENTALS: HEAT PIPE HEAT TRANSPORT CAPABILITY

In this new section, Qpedia reviews fundamental thermal engineering principles, calculations and equations needed for the successful cooling of electronics. In this issue we discuss the heat transport capabilities and limitations of heat pipes.

INDUSTRY DEVELOPMENTS: MILITARY ELECTRONICS COOLING

Modern militaries around the world are equipped with very hot-running electronics that must reliably provide high levels of performance in critical situations. In addition, thermal management for military electronics can be extremely challenging, due to the strict size, weight and power (SWaP) requirements, rugged use, harsh environments, and cost restraints. This article presents recent cooling developments for military electronics.

TECHNOLOGY REVIEW: LED THERMAL MANAGEMENT

Qpedia reviews innovative technologies developed for electronics cooling applications. This section presents selected patents that were awarded to developers around the world to address cooling challenges. In this issue our spotlight is on thermal management systems for LED lighting.
