Feeler: 9mm diode housing in copper - any interest?

[Bbe]

Yes, without active cooling. I had about 5 minutes before the module is overheated

So you don't fan or tec cool the base plate?

in addition to the above - Dave, forgive us for this chatter

[planters]

Can you describe the image? Is this CGI based on the material properties or is this an actual thermal image with the power leads eliminated? With the base plate a nearly uniform color I assume that it is aluminum and the heat flow is downward for the removal on the bottom. The limited resolution of the temperature gradients suggests that some additional temperature rise very close to the diode flange may occur. What do you think?

[Bbe]

This is a simulation in a virtual environment based on the material properties. I don't take into account the thermal effect of wires and other non-essential parts in this model. Yes, you're right - baseplate is aluminum.

The limited resolution of the temperature gradients

I checked the temperature using virtual sensor

well they are nearly done - i should have them next week.. Haha, the copper didnt play well with the 2mm taps on the cnc mill, so they are tapping all of the 400 m2 holes by hand!!

OMG! Your going to be popular! Thats some hand job...

I've not tried it with copper but many years ago I had success tapping on lathe in neutral and hand turning when it wouldn't do it driven. It was a lot easier than trying to do it entirely by hand.

They have arrived

[dnar]

Sexy. Are these only available for 9mm diodes?

Would be nice with a laserbug. What happened to them? Long time since I have seen them used....

[dave]

For the moment The 9mm diodes are the ones which really need a bit less thermal resistance in the mount I think.

I have never been a huge fan of sockets for laser diodes - Its pretty easy to simply solder direct to the diode

[buffo]

Hey Dave... Will these mounts drop in to the dual-knife-edge blue kits that you were selling a while back? Mine have the older brass cubes that were sized for the M140 diodes, but I'd like to swap them out for 9mm blues.
