peltier cooler and heatsink to be used to cool 200c to 60c is this possible?

Hi all,
Does anyone on here have experience with Peltier coolers? I have a surface 3.5 by 1 inch that is heated to 200c when current is ran through it as part of a cycle. When the current is off i need to be able to cool the surface faster than leaving it to cool in ambient temperatures, preferably in 2 or 3 minutes. Ideally i need to get the surface down to around 60c or as close as possible in this time. I cannot use any liquid systems as part of this and motors are too large as i have limited space. roughly 6 x 1 x 1 inchs of space for cooling components.

Would anyone know whether a Peltier cooler combined with a efficient heatsink and fan would work for this task? There will be no additional heat going through the heated surface at this point. It will just need the residual temperature taken down.

I understand there are issues around the solder melting and my understanding is that theres only a 70c difference between surfaces on the peltier and even then thats not under load. any advice is appreciated

Best Regards,
Joe

  1. most of the time heatsinks do not use a solder other than the material they are made of. the only thing you need to watch for is that the metal does not have a melting point of anywhere near 200c, which copper is over 1000c, and aluminum is around 600, so you should be fine with almost any heatsink

    Hi thanks for your response, my concern is with the peltiers and effectively removing that much heat from one side of the Peltier itself. Do you have any experience in a suitable heat sink that will fit the space requirements mentioned and be capable or moving the amount of heat?
  3. It won't remove all the heat of course, but will lower it, so any heatsink you can fit into the required space will do. I do not have experience with the type of cooling you are trying to do, but i do know that you are in no danger of melting a heatsink, and so should be able to at least reduce the temperature by a decent amount with any additional cooling.

    as for space requirements, do your own measurements of how much space you have, and compare them to the size of the coolers you are looking at
