BQLZRHuge TEC1-12730 253W Thermoelectric Peltier Cooler Cooling 62mm x 62mm x 4.8mm

Q: How can this be powered?

Any DC power supply (up to 15v) will work, so you could use an old AC adapter that is left over from a computer (like http://amzn.to/1Hed7kp ). You should check the Amps out because DC wall warts don't usually put out enough Amps to drive a Peltier. If you want to jump up a level, you should consider a switching power supply like (http://amzn.to/1HedETE). That one matches well to the specs of the TEC peltier. That PSU does have a fan, so it's not quiet. At that power though, don't even think about hooking it up without a decent heat sink.

Q: Can these devices be connected in series to allow me to use a 24vdc power supply?

yes you could but do not expect double performance since there is mutual influence between the two devices u can expect more cooling than from a single

Q: I have a problem to find a good cooler with 60mmx60mm dimensions to fit this peltier. Most of the existing coolers is 40mmx40mm. Any tip ?

if the space you are using this unit in will accommodate it, I am using this one https://www.amazon.com/gp/product/B01HMCYV80/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Its plenty big and has great airflow. Because of its size I recommend a high cfm positive pressure fan. Good luck.

Q: Very spiffy, but is there a middle ground btwn jumbo 6in and std. 40mm? i'm playing w/cascaded tecs trying for dry ice temps & need varying sizes.

Nothing I have seen between the 12715 and the 12730. I did see a heatsink liquid cooled 80 x 240 mm on amazon. I am cascading 5 12715 chips. I didn't think the chips would cool below zero but I may be wrong. Hope this helps.
