Comfy cars

Posted by John Day

John Day One of the more significant obstacles to automotive start-stop systems is how to keep the car comfy with the engine off. Saving fuel is great, but not if the infotainment system, HVAC et al were to shut down at every red light. At the SAE World Congress in Detroit last week, Delphi Automotive introduced a Phase Change Material (PCM) Evaporator that it said will keep start/stop vehicle cabins cooler … Read More

Robin Bornoff Like a river this blog series is slowing down due to its increased width and depth, that and a lot of travel on my part. So, let’s get it back on track! The previous blog focussed on the relatively well known 2 resistor compact thermal model (CTM) method, its strengths (simple to measure and describe) and its deficiencies (unconfirmed and inconsistent accuracy for different package styles and operating … Read More

Thermal Design Stages-Phase 2

Posted by John Wilson

John Wilson About a week ago I wrote the first part of a four part series on how I believe that Computational Fluid Dynamics (CFD) accelerates thermal design from the “Need” to “Acceptance”, which can be found here.  This second part focuses on the Computer Analysis portion of the process. I’d like to think that I am not remotely experienced enough to know first hand when desktop computers really changed the … Read More
