4. High temperature and pressure resistance, impact resistance, and durability;

5. Switching between cooling and heating modes by reversing the current direction, suitable for standard power supply conditions.

🔷Specific Applications of TEC Product

1. Laser Industry: Temperature control and heat dissipation for laser heads and laser modules

2. Medical Equipment: Biochemical analyzers, aesthetic medical devices, and small medical refrigerators

3. Precision Instruments: Temperature protection for optical lenses, sensors, and industrial control chips

4. Refrigeration Equipment: Car mini-fridges and portable refrigeration and preservation devices

5. Electronic Devices: Cooling and heat dissipation for drones, communication modules, and power amplifier components

🔷Precautions for Using TEC Cooling Plates

1. Hot/Cold Side Check

▪ Red wire = positive (+), black wire = negative (-).

▪ Power on briefly (≤3 seconds) without heat sink:

▪ Warm side = hot side; cool side = cold side.

⚠️ Do not exceed 3 seconds (risk of burnout).

2. Wiring & Power

▪ Red = positive (cooling), reverse polarity for heating.

▪ Use power supply with ripple < 10%.

3. Voltage Calculation

▪ Model example: TEC1-12706

▪ 127 = thermocouple count; 06 = max current (A).

▪ Limit voltage = count × 0.12 (127×0.12=15.4V).

▪ Working voltage = 78% of limit (15.4×0.78=12.01V).

4. Thermal Recovery

▪ Wait ≥15 minutes for TEC to return to room temperature before reuse.

5. Sealing

▪ Seal edges with 704 silicone or epoxy to prevent moisture and extend life.

6. Installation

▪ Clean TEC, heat sink, cold plate; apply thin thermal grease.

▪ Tighten screws evenly; fill gap with 25–30mm insulation.

7. Pressure

▪ Install pressure: 150–300 PSI (avoid too low/high pressure).

8. Resistance Test

▪ Test resistance with LCR meter/compensated ohmmeter.

▪ Multimeter readings are only for reference.
