🔷 Product Structure
🔷Operation Principle
Based on the Peltier effect, when DC current flows through thermoelectric cooling devices, one ceramic side absorbs heat (cold side) while the other side releases heat (hot side). By reversing current direction, this peltier module can switch between cooling mode and heating mode. Real‑time current adjustment achieves accurate semiconductor temperature control for AI, laser, medical and lab equipment.
