How Vapor-Compression Cooling Works
Vapor-compression cooling can be found in virtually any home, such as in air conditioners that remove heat from our homes and in refrigerators that store our food. The history of vapor-compression goes back to 1805 where Oliver Evans, an American […]
Advanced Cooling for Power Electronics
Power electronics devices such as MOSFETs, GTOs, IGBTs, IGCTs etc. are now widely used to efficiently deliver electrical power in home electronics, industrial drives, telecommunication, transport, electric grid and numerous other applications. This paper discusses cooling technologies that have evolved […]
Simulation Driven Design Optimization for Reduction of Temperature on a High Current Density PCB
The market demand for lightweight and cost effective electronic products with multi-functional operations leads to the introduction of plastic housing and high current density on board. In general, automotive electronic products operate in harsh environment. With high current demand, Joule […]
Someday Humans Will “See” The Heat!
Many biological creatures are enabled with the ability to “see” the heat – reptiles, for example, effectively use this ability to detect the size of the heat-emitting object and its range. Other biological entities, including mammals, are enabled with the […]
The Problem with Effective Thermal Conductivity
Simply stated, the problem with the use of volume weighted, effective thermal conductivity, kvw, in the thermal modeling of a printed circuit board (PCB), is inaccuracy. In this paper, we show how using kvw can lead to serious errors in […]
