| Building a Peltier module |

| SeanB:
Woods metal or other low melting point alloys are what is used to bond to copper. |
| Rachie5272:
Woods metal wouldn't be much use in a Peltier module because it melts at 70 °C. Having your cooler fall apart when things get hot probably isn't the best idea. For prototyping, conductive epoxy might be the easiest. |
| PointyOintment:
According to my limited knowledge, these things are usually assembled using solder. The melting point of the solder is what determines the maximum hot-side temperature—any hotter and it would fall apart. |

Are any of you all still interested in this? I have been working on making both Bismuth Telluride (n-type) and Antimony Telluride (p-type) in my workshop for the last year. I have figured out how to alloy both compounds but I don’t have the measurement tools to figure out their Seebeck coefficients. I am going to attempt to make one of these tools from scratch since the professional ones cost $9000. Anyway I would LOVE some more brainpower behind this if any of you are interested in helping. I have 100s of unlisted youtube videos of my attempts. I’m slowly organizing them. I have chunks of both Bi2Te3 and Sb2Te3 that I’ve made. I’m happy to share how I made them or just send some samples. |
