Cooling Backplate MK II
散热背甲 MK II
A Type-C-powered thermoelectric cooler made from a copper plate, insulation, a TEC-12706 Peltier module, and a 40 mm fan. I built the hardware, photographed every assembly step, and made a complete website to publish it as an open-source project.
01 / Looking back
A project and its own little website.
I made this in June 2020. The device was meant to cool the back of a tablet or almost anything else with a flat surface. The Peltier plate moved heat into the small heatsink and fan while the copper plate spread the cold side across a larger area.
I also made and sold a small number of them. This was before Xiaomi and other major manufacturers began releasing the phone-cooling accessories that later became common.
The documentation became a project of its own. I built the original site while learning HTML as I went, gave it a fixed navigation bar, and documented the build in Chinese from a pile of components to the finished cooler.
The design, language, and jokes are very clearly from 2020. I kept them that way in the archived copy.
