I am a novice user, and I am not very familier with Peltier setups, for my old CCD astonomy camera. The Peltier that was broken in the camera is not supplied by the manufacturer anymore, nor will they renovate such an old camera, so I hope that someone can help me out. I am familier with soldering wires together, and I have now purchased three Peltier units that can fit in the small space where the broken Peltier used to sit.

The Power source that runs this old broken Peltier is a 12 Volt DC, and the amps for this system is 3A.

The Peltiers are not to be connected with each other in a serial connection, but the wires from each Peltier unit is to be connected in a common joint with the wire that comes from the circuit board. Can I connect the three Peltiers, each running on 4 Volt DC and by 1 Amp, and then have them work together like they were one Peltier?

I am unsure what the physics will work like during such a setup, so just wanting to be sure, as not to damage the connection in the circuit board, before trying.

  • \$\begingroup\$ Wiring peltiers in parallel (from what I understand you're wanting to do) is very common, then these run at the same voltage and pull some current as defined by their physical properties. My worry is whether or not you matched the old broken peltier parameters with the new ones. You should match them as closely as possible. Can you provide the model# of the old peltier and the model# of the new peltiers? \$\endgroup\$ – Jarrod Christman Nov 15 '18 at 16:28
  • \$\begingroup\$ Hi Jarrod. I have removed the original peltier and it is now utterly destroyed. Nothing was written on the surface of the original surfaces of the ceramic sides when I removed it. So it is not to be determined by any manufacturing company, so I am really at a lost here. However I have configured a different way of cooling my peltier, by adding a heatsink in a way than what is originally designed. I wouls like to send you a drawing on mail, will you be willing to help me out by letting me write you? \$\endgroup\$ – janL1978 Nov 17 '18 at 11:15
  • \$\begingroup\$ We’re here to help. Though if you can, edit your question with the drawing so others can try and help as well. Though without the original specs it’s hard to say how well the new one will match in performance. \$\endgroup\$ – Jarrod Christman Nov 19 '18 at 2:20
  • \$\begingroup\$ Hi Jarrod. Thanks, I appreciate it. I cannot seem to find a way to share any drawing I make on this site here? How do I do that? \$\endgroup\$ – janL1978 Nov 19 '18 at 19:19
