🔷 Product Structure
Top alumina ceramic substrate → N‑type & P‑type thermoelectric pellets → copper conductive tabs → bottom alumina ceramic substrate → lead wires. Two‑sided ceramic insulation structure ensures high‑voltage safety for this peltier module.
🔷Operation Principle/ Work Principle
Based on Peltier effect. When DC current flows through the peltier module, one side absorbs heat for cooling, the other side releases heat. Swap DC current polarity, cooling and heating side will reverse. Realize active precise temperature control without compressor.
