OOOh I se
Many many thanks Adam!

Adam,
I would try TEC w driver
Having read this long thread but don't know where to order a simple TEC driver d4chill seems out and this is also an old thread

any info where to order some "simple" TEC drivers?
many thanks!

Big lumps of metal are what you want.

These are my 2 new modules (1x 462, 1x 445, 2x P73), the base plate and diode mounts are machined out of one big lump of ally!

Not my handiwork unfortunately But beautifully crafted I think, and totally in keeping with my KISS principles.

You can check on E-bay... They usually have some good deals. Example: http://www.ebay.com/itm/Temperature-...p2054897.l4275

Also, Banggood.com has some nice temperature controllers. Example: http://www.banggood.com/REX-C100-100...-p-914678.html

Thanks Adam ,I see. These are relay type on/off temperature controllers, similar to this kit in spain:

I was referring to current controlled by thermistor, like the drivers d4chill made some years ago. For a better stable control.. not an ON/OFF cycle
Thanks anyway really appreciated

nice build norty!
Anyway my baseplate is 300x300mm 10mm thick +4 fans. I guess even without tec will do its job well

Those "on-off" controllers are remarkably accurate. I've seen less than 1 degree shift with them.

ok I'll try Adam

The on-off controller buffo pointed out work very good. I have them on 1 projector and also on some heat tape to protect my pipes in the winter. Only complaint is they use a mechanical relay that probably wont last forever.

Back to the original picture..... I would stay away from #2. If the hole is bored just slightly bigger than the module the heat transfer will be awful. Even with thermal grease. The slotted clamp style should give better contact all the way around the module. (if the hole is very close to the module diameter)

thanks for the info!
I've seen several temp controllers with TRIAC. these could be connected to the tec Psu (on AC 110v input) thus avoiding the need for mechanical relay, but think these dont work well with inductive loads. I have to investigate!
