🔷 Performance Curve
🔷 Product Overview
TEC1‑12704 thermoelectric peltier device 50*50mm is a solid‑state thermoelectric cooling module, also known as TEC cooler.
As a reliable large‑size thermoelectric peltier device, it converts electric energy into temperature difference without refrigerant. Our factory supplies wholesale thermoelectric peltier device and accepts OEM & custom thermoelectric peltier device service for global buyers. It is a popular solution for active thermal control projects.
🔷 Product Features
🔷 Product Structure
🔷Operation Principle
The thermoelectric peltier device works based on the Peltier effect.
When DC current flows through the module, one ceramic side absorbs heat and becomes cold, while the other side releases heat and becomes hot. By reversing the direction of DC power, this TEC cooler can switch between cooling and heating mode. For stable cooling performance, the hot side must be equipped with an effective heat‑dissipation system such as a fan heat sink or water‑cooled cold plate.
🔷 FAQ
Q1: Are you a thermoelectric peltier device manufacturer? Can I buy TEC1‑12704 in bulk?
A: Yes, we are a professional thermoelectric peltier device manufacturer. Wholesale thermoelectric peltier device and bulk‑order service are supported.
