🔷Key Advantages of TEC Cooler
1. Miniaturized and easy to integrate: 3.25mm ultra-thin profile; elongated design suitable for linear or narrow heat sources; weight <5g.
2. No mechanical movement: No noise, no wear, and no refrigerant; service life of 5+ years (under normal operating conditions).
3. Low-voltage safety: 3.8V low voltage, compatible with USB and lithium-ion battery power sources; ideal for portable devices.
4. Bidirectional Temperature Control: Cooling when powered forward, heating when powered in reverse, with a temperature control accuracy of **±0.5°C** and fast response.
5. High Reliability: Ceramic substrate provides insulation and moisture resistance, suitable for environments ranging from **-20°C to 80°C**
🔷Product Application of Element Peltier
1. Digital Cooling: Cooling back covers for smartphones, LED chips, micro-projectors, temperature control for portable digital modules
2. Beauty and Personal Care: Ice-point hair removal devices, eye cooling devices, small facial cooling appliances
3. Precision Optoelectronics: Temperature control for small optical modules, infrared sensors, and micro-camera image sensors
4. Portable Temperature-Controlled Refrigeration: Mini portable coolers, small in-car food storage containers
5. Small Appliances / Industrial: Micro dehumidification modules, small-area temperature control for instruments, temperature control for 3D printer nozzles
6. Smart Wearables: Temperature control for specific areas of fitness bands and watches
🔷Peltier Cooling Element's Performance Curve
🔷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.
