TEC heat sink

For any one looking for a good TEC heat sink I just come up with this design it used a 19mm thick slab of Aluminum
and has a threaded copper module that mates with the aluminum block in a recessed and threaded hole.

Your TEC can be bonded directly to the surface or both surfaces if you want even more cooling.

Threaded mounting holes can be placed to your spec's if you need them.

This is the aluminum block with a copper module and a tool for inserting and removing the module.




As you can see there is only a few thousands between the copper module and the aluminum so a little heat sink compound is all that is needed.




the block and threaded copper module is $35.00 and a tool is $5.00, obviously the tool can be used with any Aixiz
type module and can be used to pull a stuck module out of a tight heat sink

Thanks for looking.

Nice... I like it and I love the insertion/extraction tool.

I see that the block is 19mm thick. What are the block
outside dimensions.

I suppose there is a small hole on the other side for the wirings.

Thank you Jerry, the outside dimensions on the one pictured in this thread is 50 x 64mm but you can have it just about any size you want

@ Blord yes there is a hole all the way through the block for the diodes power leads, I made it only big enough for the leads this gives a shoulder
up close to the back of where the laser diode will sit that a thin cardboard disk could sit on in case you want to put some heat sink compound in
there to draw off the heat from the back side of the laser diode

The diodes leads will have to go through the cardboard disk and the disk will help trap the compound up against the back of the LD and squish it
against all the internal walls when you screw in the module for the best heat transfer.

Very COOL. Just saw this thread. My Q about whether the diode is a Non Press fit to the module or are these just regular back threaded modules? Somewhere I saw a diode mount system something like this where just the diode could be set into place think it was screwed in the back with a hole in the screw for the diode leads.

I thaught that was your design.. I am thinking now that these are just regular back threaded modules. Diodes are going to end up in a module anyway's for the most part.

Is the leads hole large enough for a 9mm diode?

There are other styles of heat sinks also available>

Wouldn't it be better if the aluminum block has fins?

That would depend on how you are planning on using it, if you wanted a fan to blow on it then yes fins would be great
but if you wanted to attach it to a TEC cooler then fins would be no good :thinking:

Sorry, I got it messed up. I was thinking that the TEC would go to one face of the block and the other face would be finned to aid heat dissipation.

Well yes that would be good and I can make that happen if you like
