Ercan M. Dede INTRODUCTION Single-phase liquid cooling is an established approach to the thermal management of highly-reliable hybrid vehicle power electronics. However, as the electrification of hybrid vehicles increases and under-hood space becomes further constrained, semiconductor device power densities continue to rise (in excess of 200 W/cm2) resulting in … [Read more...]
Circuit Credit Card Assembly Heat Sinks Embedded with Oscillating Heat Pipes
Joe Boswell, Chris Smoot, Elliot Short, Nate Francis Introduction In this study, lightweight two-phase heat sinks embedded with the Oscillating Heat Pipe (OHP) technology are developed for the thermal management of military circuit card assemblies (CCA). OHP-embedded heat sinks efficiently transport heat generated by CCA centrally located components to the assembly’s … [Read more...]
The Electronics Cooling Metaphorical Drinking Game – Part Deux
With Semi-Therm 31 just a week away I thought it would be a good time to expand on the (metaphorical) electronics cooling drinking game. Something extra to add to your enjoyment of a conference presentation, journal paper and especially a press release. Common electronics cooling industry drivers and concepts crop up again and again (well, they would do, they’re … [Read more...]
Mentor Graphics at Semi-Therm 31 – ‘Dolly the Heatsink’ and much more
Semi-Therm, the world’s largest dedicated electronics thermal conference, will take place between March 15-19 at the Doubletree Hotel in San Jose, California. Now in its 31st year, this IEEE sponsored conference maintains its high standards in peer-reviewed papers covering a range of disciplines within the electronics cooling field. As usual, the Mechanical … [Read more...]
3D Thermal Simulation of 2D Images – A Valentine’s Love Story
A full 3D thermal simulation of an electronic system requires, not surprisingly, a 3D geometric representation of the proposed design. Much of the design data for a phone, laptop, blade server, IGBT cooling system, etc. often already resides in an MCAD system and is readily importable into FloTHERM or loadable into FloTHERM XT. EDA design data, be it a PCB layout or BGA … [Read more...]
