Thought i'd post this here....someone might find it a good alternative :D

So...i ordered the wrong size copper back half from DTR's shop, needed the half backs....

The IC of a driver fits nicely on the shelf, abit of acrtic silver and a :beer:

That's a good idea, I thought of trying something along those lines myself.

Lets see some pics when you put it into action !

Re: Modified full copper back half from DTR

By removing a lot of the copper from the module it might not transfer heat as well to the heat sink. This might not be a problem with lower power builds, but I wouldn't use it for a 5+ watt build. I hope you are going to use it for one of these 275 mA builds.

Hi Paul,
As you know my sinks have plenty of mass in diameter. and length , so for me with the high powered diodes it won't be an issue . But as you said if its cut down to much keep with the lower powered diodes to be safe.

Re: Modified full copper back half from DTR

I didn't know you were cutting down copper modules too, Rich. Yes, your copper heat sinks are very good at moving heat away from a diode. I love the thermal properties of copper. For the money, it's the best material around for this purpose.

Re: Modified full copper back half from DTR

Hi Paul,
I make the heat sink a little longer then cut away a portion of the back to reveal the shelf. Its two cuts and then finishing. Or the other way i will drill out the center as normal with a 12mm drill. Then bore out the back larger to fit a copper half moon to sit the driver on. They work out quite well.

But, they still take a 12mm module, don't they, Rich? You don't cut down 12mm modules, do you?

Hi Paul ,
yes it still will take a 12mm copper module , the 12mm will side in as usual with the set screw and the shelf will be in the back portion of the sink.

Hi J,
Well thank you very much for the kind words, I try my best at building hosts and sinks .
