🔷 Performance Curve

🔷 Product Overview

Our TEC1‑12705 Thermoelectric Cooler 40*40mm is a compact‑size thermoelectric cooling device module built‑in high‑quality bismuth‑telluride thermoelectric pellets. As a solid‑state thermoelectric cooling device thermoelectric cooler, it transfers heat from one ceramic side to another side without refrigerant, compressor or moving parts.
Different from large size 100x100 thermoelectric cooling device element, this 40×40mm TEC chip takes small installation space, perfect for medium‑power temperature‑control projects. We are a professional thermoelectric cooling device supplier, supporting wholesale thermoelectric cooling device and OEM thermoelectric cooling device module service for global buyers.


🔷 Product Features

  1. Solid‑state cooling, no vibration, low noise for thermoelectric cooling device refrigeration
  2. Precise semiconductor temperature control, cooling & heating reversible
  3. Compact 40*40mm footprint, easy for assembly
  4. Stable performance, long service lifespan
  5. Available for bulk wholesale and custom thermoelectric cooling device cooling plate solution
  6. Fast temperature response, simple drive circuit

🔷Product Applications

This TEC1‑12705 thermoelectric cooling device is widely used for:
✅ Thermoelectric cooling device for industrial chiller
✅ Thermoelectric cooling device for laser cooling
✅ Small‑size semiconductor temperature control equipment
✅ Medical constant‑temperature instrument
✅ Laboratory cooling & heating platform
✅ Mini refrigeration cabinet, beverage cooler, beauty cooling equipment
✅ Electronic component heat dissipation


🔷 Product Structure

🔷Operation Principle

This thermoelectric cooling device runs on the Peltier effect. When DC current flows through the thermoelectric cooler module, heat will be absorbed on one ceramic surface (cold side) and released on the opposite ceramic surface (hot side). By reversing the DC current direction, the cold and hot sides will swap, so the thermoelectric cooling device can realize both cooling and heating function for semiconductor temperature control. A matched heat sink is required to take away heat from the hot side during continuous operation.


🔷FAQ

Q1: Can I get this TEC1‑12705 thermoelectric cooling device by wholesale order?
A1: Yes, we are a reliable thermoelectric cooling device supplier, we support wholesale thermoelectric cooling device with competitive bulk price.

Q2: Can you provide OEM thermoelectric cooling device module service?
A2: OEM service is available, we can offer custom thermoelectric cooling device cooling plate, different wire length, surface treatment according to your drawings.

Q3: Is this 40*40mm thermoelectric cooler suitable for laser cooling?
A3: Yes, this thermoelectric cooling device for laser cooling is a very common solution for small laser module temperature stabilization.

Q4: What power supply do I need for TEC1‑12705?
A4: Recommended DC power: 12V‑15V, maximum working current 5A. Constant‑current power supply is suggested for better semiconductor temperature‑control effect.
