In the past, the thermal designer's role was seen as one of predicting temperatures and ensuring that reliability limits are met for products. However, the role of an effective thermal designer is much more than that. We believe that thermal designers are both critical and most useful in the early conceptual stages of product design. This is where they provide the most "bang … [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...]
An Introduction to Pulsating Heat Pipes
Modern electronics thermal management faces considerable challenges in the wake of component miniaturization, which has led to higher demands on net heat flux dissipation. With the industry closely following Moore's Law, the future demands are becoming increasingly more challenging [1]. Two-phase passive devices are proven present day solutions. Conventional heat pipe … [Read more...]
Power Density Challenges Of Next Generation Telecommunication Networks
Despite the current downturn in the telecommunications industry, data transfer (i.e. network traffic) is continuing to grow at a 100% rate [1]. It is already projected that network traffic demand will reach tens of Tb/s in a couple of years from now (see predicted traffic demands from telecommunications analysts Ryan, Hankin & Kent, Figure 1). At the same time, network … [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...]
