As the complexity and power density of electronics systems increase, so too does the demand for tools to improve both product quality and designer productivity. This is especially true for thermal designers who use Computational Fluid Dynamics (CFD) tools for thermal designs. Several important factors are driving this trend: System complexity has increased to the point that … [Read more...]
Direct liquid immersion cooling for high power density microelectronics
Introduction Since the development of the first electronic computers in the 1940s, thedevelopment of faster and denser circuit technologies and packages has beenaccompanied by increasing heat fluxes at the chip and package levels. Over theyears, significant advances have been made in the application of air coolingtechniques to manage increased heat fluxes. Although air cooling … [Read more...]
A valve-less fluid pump for electronic cooling
In a research project at the Royal Institute of Technology we have developeda pump based on a new fluid pump principle with no valves. The pump consists oftwo fluid flow rectifying diffuser/nozzle elements which are connected to theinlet and outlet of a pump chamber with an oscillating pump diaphragm, as shownin Fig.1. The diffuser/nozzle element has a lower flow resistance in … [Read more...]
