Thermal - Thermoelectric, Peltier Modules

1. Overview

Thermoelectric Peltier Modules (TEMs) are solid-state devices that utilize the Peltier effect to transfer heat between two electrical junctions. When direct current (DC) passes through a thermoelectric material, heat is absorbed on one side and released on the opposite side. These modules enable precise temperature control without moving parts, refrigerants, or maintenance, making them critical in modern electronics, medical devices, and industrial systems.

2. Main Types and Functional Classification

TypeFunctional FeaturesApplication Examples
Standard TEMsBalanced cooling capacity and costIndustrial temperature control systems
High-Power TEMsHigh T (temperature difference) and large heat pumping capacityLaser diode cooling, power electronics
Microminiature TEMsSub-centimeter dimensions with precise thermal regulationMedical sensors, infrared detectors
Multistage TEMsCascaded design for ultra-low temperature applicationsCryogenic systems, scientific instruments

3. Structure and Components

A typical Peltier module consists of: - Ceramic substrates (high thermal conductivity electrical insulation) - Thermoelectric elements (Bismuth Telluride - Bi2Te3 based semiconductors) - Copper interconnects (low electrical resistance) - Solder junctions (thermal and electrical bonding) - Epoxy encapsulation (moisture protection)

4. Key Technical Specifications
