Following some recent talk about coldplate geometry and other's simulations, I've decided to work on a few idea that have been sitting in the back of my mind.
The equations for thermal and electical conduction are analogous, so it ought be possible to use the readily available software for electical simulation and turn it to the task of thermal simulation. To that end I've been assembling arrays of resistors, capacitors, and voltage and current sources. In simple tests, like uniform heat flow through a rod, or a point source on an infinite plane, simulated results match expectations.
So now it's time to take it up a notch.
What I'm looking for is estimates/theories/guesses for
h, for a fairly uniform waterblock. Something like a #rotor block or the MCW5000A. I want to see how a coldplate-TEC-waterblock system reacts to changes in coldplate geometry, and how the system reacts to heat transients.
Off topic -- I've been using LT-Spice. At 8:10 this morning, I sent and e-mail to Linear reporting two bugs. At 3:30, they sent a reply indicating that problem was solved and updated binaries were available.
