Description Description

1. The core of the Peltier module is an N/P type semiconductor thermocouple, ceramic plate encapsulated, achieving solid-state heat transfer via DC current.

2. Charge carriers absorb heat at the cold end and release heat at the hot end; reversing the current switches to heating mode.

3. The module's temperature difference is directly related to the current, semiconductor performance, and hot-end heat dissipation efficiency.

4. The TEC1-12706 is small and only suitable for cooling small devices requiring effective heat dissipation.

5. Includes an aluminum heatsink with thermally conductive tape, a 12V 4010 bearing cooling fan, and mounting screws.

6. Never connect the power supply without the heatsink installed; otherwise, the TEC module may burn out.

7. A low-voltage 5V power supply can be used to check the module; a heatsink and fan are required for auxiliary heat dissipation at the hot end.

8. Optimal cooling at 12V requires a higher-power cooling device; avoid exceeding the rated voltage and current.

9. An aluminum heatsink can be connected to the cold end, providing both heat conduction and anti-frost functions (optional). Under 10.12V 6A conditions, the built-in 4010 fan is insufficient for heat dissipation, and a higher power heatsink is required.
