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

[tiefbassuebertr]

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:

second try for the heatsink photos:

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.

Hello Magura, I can imagine your "joy" with the round designs. I do have access to a machine shop. However, I wasn't thinking of that exotic. I was thinking of gutting out a couple 3.5-5hp engines and stuffing the circuitry into the engine block. Perhaps a Zen or F series, modded to fit the enclosure. One engine block per amp channel. Call it the Pass and Stratton Zen Clone!

 

[dave_gerecke]

That's about right.

Somebody get me the KY, that just hurts!

Oh, a StrattoPass

Yeah, I had my share of work hours with those in the pic. They have soon been "in the process" for 9 years.

Magura

 

[dave_gerecke]

StrattoPass, I like that! I have seen the amps you designed elsewhere in this fine bin of insanity we inhabit virtually. The real question after all of the work to make it acceptable to SWMBO, is how does it sound?

Peace,

Dave

 

[Magura]

SWMBO is very flexible in that regard. She thinks they look fine, so I can keep them

No sound yet, but I hope to be presenting them at the:

diyAudio - Danish DIY festival


I just got the last few parts. Things got delayed due to all the snow.


Magura


EDIT: Dave, where is that "extra word"?

 

[dave_gerecke]

Hello Magura, so you have gotten a lot of snow in Denmark. We recently set a single storm record for here in Burlington Vermont. In one storm last weekend we got over 33 inches (84cm) of snow. Funny thing is that the mountain to our east didn't get much snow at all. The storm centered right over us!
The extra word wasn't anything too important, bad grammar on my part. I have no issues with people who English is a second language having some mistakes with their grammar, but I like to think I should be able to write in English correctly!

Peace,

Dave

P.S. Good luck with the power up and listening. I hope you shock them at the festival!

 

[Magura]

We only got like 12" of snow, but that's enough to make everything stop in Denmark.

I like that you put in an effort to use the right grammar and so forth, many of the native English speakers don't. Us non-native English speakers learn from you, we might as well learn correct grammar

In fact, yes

And then we have Zen Mod. Who demonstrates that he has also mastered American slang English well!
