🔷Performance Curve




🔷 Product Overview

TEC1‑09103 Thermoelectric Cooler 40*40mm is a high‑power TEC peltier element. As one popular TEC thermoelectric cooling chip, this 40×40mm thermoelectric cooler transfers heat by the peltier effect, achieving fast active cooling and precise temperature control. Our 40x40 TEC thermoelectric cooler belongs to industrial‑grade TEC module, widely supplied as bulk TEC cooling module for wholesaler, OEM and custom‑made cooling projects.




🔷 Product Features

  1. Large‑size 40*40mm ceramic surface, excellent heat‑exchange efficiency
  2. High temperature difference TEC cooler, stable cooling performance under long‑time operation
  3. Industrial grade TEC thermoelectric cooling module, low noise, no vibration, no refrigerant
  4. Compact solid‑state structure, easy to install and integrate into small cooling systems
  5. Flexible cooling & heating dual‑function, precise temperature adjustment
  6. Available for wholesale TEC peltier module, OEM TEC thermoelectric cooling chip and custom TEC thermoelectric cooler service




🔷Product Applications

This TEC1‑09103 thermoelectric cooler 40*40mm can be used in many cooling scenarios:

  • TEC thermoelectric cooler for industrial chiller and small industrial cooling equipment
  • TEC peltier module for laser cooling, laser diode temperature stabilization
  • TEC thermoelectric cooling for medical equipment, medical analyzer constant‑temperature control
  • TEC chip for semiconductor temperature control, electronic component heat dissipation
  • TEC thermoelectric cooler for laboratory refrigeration, lab small thermostat, test chamber cooling
  • Beauty equipment, mini refrigerator, humidity‑control cabinet and other commercial cooling devices




🔷 Product Structure





🔷Operation Principle

This TEC peltier module works based on the Peltier effect. When DC current flows through the TEC thermoelectric cooling chip, one ceramic side absorbs heat and becomes cold, the opposite side releases heat and turns hot. By reversing the DC current direction, the cooling side and heating side can be swapped. It is an efficient solid‑state solution for active temperature control without compressors.




🔷FAQ

Q1: Can I buy sample before bulk order of TEC1‑09103 thermoelectric cooler 40*40mm?

A: Yes, samples are available. We are a professional TEC thermoelectric cooler supplier, we support sample testing before wholesale TEC peltier module & bulk purchase.

Q2: Do you offer OEM TEC thermoelectric cooling chip and custom TEC thermoelectric cooler service?

A: Custom service including wire length, connector, ceramic modification and special parameter OEM is acceptable. Contact us for custom drawing review.

Q3: What heat sink do I need to match this 40x40 TEC thermoelectric cooler?

A: A high‑performance heat sink with sufficient airflow is strongly recommended. Good heat dissipation is critical to reach the max temperature difference of this high‑power TEC thermoelectric cooler.

Q4: Is this TEC1‑09103 suitable for laser cooling and medical equipment projects?

A: Absolutely. This industrial‑grade TEC thermoelectric cooling module is widely used for laser cooling, medical device constant‑temperature control and laboratory refrigeration.
