🔷 Product Overview
TEC1‑19904 thermoelectric cooler 40*40mm is a classic‑size semiconductor cooling plate, also known as peltier module or thermoelectric peltier cooling chip.
Compared with large‑size 100x100 peltier module, this 40‑mm square thermoelectric cooling element takes compact space while delivering reliable cooling output.
As a professional bulk thermoelectric peltier manufacturer, we supply both standard‑stock and custom‑made high‑power peltier module. We serve global buyers who look for peltier module supplier, thermoelectric cooler bulk purchase and OEM cooperation.
🔷 Product Features
- Compact 40×40mm square ceramic structure, easy to install
- Stable cooling performance, low noise, no compressor required
- Bidirectional temperature control: cooling & heating switchable
- Wide working temperature range, long service life
- Support OEM modification and custom‑made high‑power peltier module
- Available for wholesale thermoelectric cooler bulk‑order purchase
🔷Product Applications
This TEC1‑19904 peltier chip is widely used for multiple temperature‑control scenarios:
- Thermoelectric cooling for industrial chiller
- Peltier module for laser cooling
- Semiconductor temperature control for electronic cabinets

🔷Operation Principle
The thermoelectric cooler works on the Peltier effect. When direct‑current flows through the peltier module, one ceramic side absorbs heat and becomes cold, while the opposite ceramic side releases heat. By reversing the current direction, this thermoelectric peltier cooling chip can switch between refrigeration and heating mode, realizing accurate semiconductor temperature control.
🔷FAQ
Q1: Can I get sample of TEC1‑19904 thermoelectric cooler 40*40mm?
A: Yes, samples are available. As a reliable peltier module supplier, we support small sample test before bulk thermoelectric cooler purchase.
Q2: Do you offer OEM TEC module and custom peltier cooling plate?
A: Custom‑made high‑power peltier module and special cooling plate service is acceptable, we can adjust dimension, wire length and power according to your drawings.
Q3: What other high‑power peltier modules can you provide besides TEC1‑19904?
A: We have full‑range thermoelectric coolers, including TEC‑1‑24125, 100x100 peltier module, large‑size high‑current large peltier element for industrial thermoelectric cooling system.
Q4: Is this 40*40mm peltier module fit for laser cooling and medical equipment cooling?
A: It is suitable for low‑medium power laser cooling, lab cooling and small‑size medical semiconductor temperature‑control projects. For high‑heat‑load scenarios, we recommend high‑power 100*100 thermoelectric cooler module.
