Conventional axial hub-motor AHS (Active Heatsink) devices (Figure 1) have reached their functional and cost limits and may not be improved significantly. These devices have a number of inherent, severe contradictions (design limitations) that determine the "evolutionary maturity" of this concept. Figure 1. Conventional axial hub-motor AHS. Let us look at different … [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...]
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...]
Effective Thermal Design for Electronic Systems
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...]
Estimating Parallel Plate-fin Heat Sink Pressure Drop
In the last issue of ElectronicsCooling a methodology was presented for estimating parallel plate-fin heat sink thermal resistance [1]. The method presented assumes that the air flow rate is given, either in terms of the average velocity, V, between the fins or a volumetric flow rate, G. Although this methodology was shown to be useful in examining the effects of heat sink … [Read more...]
