Heatsink Design like NIRO and wanted for ZEN/Firstwatt SE projects - where to order?

tiefbassuebertr · 6th January 2010, 08:57 AM

I have found a very special heatsink design. Also interested for diy projects, e. g. ZEN "Delight" and some other ZEN/Aleph variations. Where are made this heatsinks?

I don't find it by the follow companies:
Heat sink producer Aavid Thermalloy - World Leader in Thermal Management
Conrad Heatsinks
f.cool
Taisol CMK702151A Copper Heatpipe Heatsink Review - FrostyTech.com

Here some photos of the heatsinks, that I mean:

That is a custom heatsink designed by the audio company and manufactured by an extrusion company. My guess would be that the extrusion die itself probably cost $5,000.00 US and then you would pay so much per weight of the extrusion.

Oh, that looks real familiar

Looks like cylinder heads from an air cooled engine!

mmmmmm

woodturner fran, thanks for the idea! now I have another source of unique heatsinks. There's never a shortage of blown engines from lawnmowers, etc.

Peace,

Dave

Hey Dave,

Now all that's left for you, to get a real nice multiple heatsinks chassis, is to figure which lawnmower is particular lousy quality, so you can get all your heatsinks in the same design

Hey Magura, that isn't a problem around here. It isn't that they are of poor quality, it's just that it's cheaper to replace than repair around here. Therefore I find a lot of old Briggs and Stratton and Tecumseh's that are discarded.

So finding multiples of the same design shouldn't be a problem. I have a friend with at least six lawnmowers laying around his place, some I gave to him. I imagine I could acquire a couple engines without any problems. Perhaps I gut the engine and put the circuit inside the cylinder bore. Use the entire engine housing as the heatsink!

Peace,

Dave

Dave, a word of advice.
As you can see from the above pics, I've been playing around with round designs. Trust me, you don't wanna go there, unless you have a machine shop or the like at your disposal.

That's about right.
