Pretty sure I have the most awesome neighbor . . .

[boscoj]

it's a long story and I'm still uploading the pics and videos . . .

I knew my neighbor was a bad ass machinist but I didn't really know how bad ass until this evening . . .

Amazing stuff as he found the "actual center" of this i7 heatsink . . .

Me - "So what do you do?"
Him - "I build prototype medical robots . . ."

hmmm . . .

Then proceeded to bore a 11.99(5) mm hole, "in the exact middle" for my AixiZ/DrLava/Whatever module . . . finger press tight about 5 mm reveal . . .

Sweeeeeeeeet

Now drop in a A140 and crank it to 2A :evil:

 

[laser_freak]

Sweet! What kind of equipment did he use? I have a heatsink identical to yours which I am itching to use.

 

[blu-ray laser]

what could you possibly fit that in?! lol.
the size of that heat-sink is hysterical compared to the AixiZ.
all I can say is wow.

 

[Meatball]

Go for a D size Maglite. You know you want to.

 

[wolfhunter9154]

Is that a socket 775 heatsink?

 

[Flaminpyro]

Finding the center of that heastsink is not a problem I could do it in a few seconds, The problem is finding a very cool heatsink like that one :drool:
Where did you come up with that beast

Uh, it's a stock intel E29477-002 socket 1366 heatsink.

Though personally I prefer these.

While they don't have copper core's, they cost 1/4 what the above heatsinks do.. A whopping $3.18 in quantity.. which is why I bought 20 and my supplier has a few thousand in stock.

I can get the above intel 1366 heatsinks, as well as intel 775 ones that have a lower fin density fairly cheap as well, but like I said, not nearly as cheap as these aluminum ones.

Expect to see them popping up in the BST bored for aixiz modules as soon as my bag of modules actually gets here.

Though for someone wanting to go all out, i'd probably suggest this.

Though with copper fins, it's not going to be machinable, diameter wise.

It's the i7 extreme stock heatsink. The next step up from the one boscoj is using.

 

[nikokapo]

So why does Proto need medical robots?

 

[Gryphon]

Now just imagine over 1W of blue light streaking out of the center at its doomed target

 

[blu-ray laser]

Incineration would be immenent for the target. All you would hear is a little poof as whatever it was burst into flames.^^^

Pretty neat. Although, the diode probably wouldn't care if you found absolute center or not.

You should have had him drill it out and tap it for an Aixiz lens thread, then set the rear in some, and bore a recess so the diode could be pressed directly into the sink instead of into a module.

I have been looking through various CPU and VGA heatsinks for the TEC cooled 445nm I am building right now. I will say, computer thermal items mix with lasers very well. The 445nm diode really desires this kind of stuff that would normally be overkill in other circumstances.

The idea I had for my current 445 lab laser is to machine a diode pinch mount block made of copper. That block mounts on the front of a 3/16" thick sheet of copper. Just behind the diode block sits the 40x40mm TEC on the sheet of copper. On top of the TEC plate sits a square VGA cooler for the hot side. The VGA cooler tabs are secured to the copper plate with machine screws to make a nice tight sandwich of the three items.

Dude... this is your third thread saying the same thing.... keep all the updates / info in one thread.

Thanks

From a heat transfer standpoint that would be better, especially if the diode was pressed in with some indium foil. However, that's fairly complex machining to ask your neighbor to do for free. Plus in general, I don't think most people really want to have their diodes permanently tied up in a build, even if they do end up never taking them apart. Boring a hole for an aixiz module is fairly quick and simple. Plus you can always pull the module out again and use it in something else without destroying the diode in it.

 

[Fonduman]

now do it so diode press fits in, and in pure silver

preferably with circulating liquid helium around the edges.

 

[boscoj]

Yeah sorry, have some wierd refresh problem with opera . . .

What I don't understand is why the other thread with all the pics has fewer replies/views than this one.

I would delete this if I could . . .
