Metaldanske tell me something about carbon heat spreaders

[Magura]

What do you want to know? I mean more specific?Magura / Whom declared the Donut project "finished" last Sunday.

Is it works or white smoke is released?

thermal and physical characteristics , of those pieces you use ;what's temp difference of mosfet case and heatsink

[Magura]

Thermal characteristics are about the same as of copper. Look up graphite, and you got it. The big deal is that it has higher thermal transfer capacity in the direction of the fibers, so you can make two components track quite well thermally. I can't remember the temp differences of the case to carbon heat spreader, but I'll measure that this evening. Why such interest all of a sudden? Magura

Choky is up to something. Something is brewing. First he was asking that question about chokes, now this... I guess it is an amp with chokes and with some devices that needs fast cooling.

[Magura]

Yeah I had that feeling as well....spill the beans fluffy Serb Magura

It works very well, and the magic smoke stays inside the 3 legged critters Magura

Another high quality image Anyhow, it shows that the donut project actually did end up as a pair of amps.Magura

Is that water cooling for the amps in the back, or the cooling on the amps is so good that you have to warm up the amps in order to work well? Looks magnificent!

[Magura]

Naah, just not that many options, when it comes to placing the system. Not that it makes any difference actually, but I too thought it would, so I measured the temp of the amp, once in place, and then moved away from the radiator....about 1C difference And now for something completely different: I have made a CLEAR photo. Mucho effort, but worked.Magura

[Magura]

The temp difference from the critter to the carbon heat spreader, is some 4 to 5C, a bit hard to get to measure.IRF244 critter runs at around 45C, sinks are maxing out at 30-32C, some 9C above ambient.Magura

Metal man, are you coming to BAF this year? We might have a class exchange. You do milling class and I will teach you all that you need to know about photography.

[Magura]

I hope that circumstances and time permits that I come to the BAF this year. .....and that is a very good offer Vladimir. I'll take you up on it.Magura

[Zen Mod]

now ..... I just need to secure good mortgage , to be able to visit this year's BAF ...I'll teach ya everything else ...... :blush:who is familiar with Goonies ( http://www.imdb.com/title/tt0089218/ ) , knows meaning of "everything" :(Mighty ZM

Here you are, we have been talking about your secretive project...

[Zen Mod]

naah ..... as I told to Metalkid in PM , nothing new and nothing secret - at least to you two ;everyday life is sometimes overwhelming

[Magura]

I had a friend visiting me today.His first comment when he entered the living room was : Oh they're big!Now my first thought was : quit ogling her titsAfter some thought, I realized he meant the Donuts.Funny thing is, just like with tits, that when you see them every day, after some time they don't seem all that big.........it's just that all the other amps/tits seems soooo small Magura
