Electronic content in cars and trucks has significantly increased in the last 30 years. Much of the functional content of these vehicles is now generated or controlled by electronic systems. This trend will continue in the future, as more mechanical functions are converted to electronic and electrical functions. A list of many current automotive electronic functions can be … [Read more...]
Cooling of a Flat TV Monitor
Thermal design in the consumer electronics business is about dealing with two difficult challenges: The first is to fulfill, and if possible surpass, customer expectations. The second is to do this in ever shortening design cycles. After a main initial use of flat displays as computer monitors, larger flat display screens are now emerging for video purposes: the Flat TV. … [Read more...]
A Few Design Techniques On How To Reduce The Power
There will always be the need to get heat out of high power circuitry, but with a little extra design effort up front, we may be able to reduce overall power needs. Here are two techniques that can help do that. Turn Idle Circuits Off A circuit that is not always used can be turned off until needed. This is a technique widely used in battery powered electronics, but it can be … [Read more...]
Challenges In Thermal Control Of Military Electronics Systems
Thermal design engineers working in defense electronics are facing many challenges, some of which have been around for a long time and some that are more recent. Worldwide climatic extreme temperatures are reasonably constant and there are many military electronic systems that function in these extremes. As a result, there is significant design history available for … [Read more...]
Packaging And Temperature Control Considerations For Planar Waveguide Circuits
Optical Networking The all-optical network has been emerging as a solution to provide higher bandwidth, lower cost systems for handling high capacity network traffic. Due to the inherent limits of copper wire and the high cost-per-bit of electrical systems, service providers will replace electrical components with fiber optic counterparts wherever possible as the cost of the … [Read more...]
