Thermal - Thermoelectric, Peltier Modules are solid-state devices that function as heat pumps. Using the Peltier effect, they create a temperature difference across the module when an electrical current is applied, allowing for heat transfer from one side of the module to the other. This results in the cooling or heating of an object or fluid in contact with the module. The main functions of thermoelectric Peltier modules include precise temperature control and maintenance for applications where traditional cooling methods are less effective, as well as energy generation by converting temperature differences directly into electrical energy.
These modules are commonly used in applications such as electronic cooling, where components must be kept at optimal temperatures to prevent overheating and ensure performance and reliability. They are also used in portable refrigerators, climate-controlled seats, and medical devices that require precise temperature regulation. Characteristics that define Peltier modules include their compact size, lack of moving parts, which leads to less maintenance and longer life spans, and their ability to heat and cool with a simple reversal of the electrical current. Some of the well-known manufacturers of Thermal - Thermoelectric, Peltier Modules include TE Technology, Inc., Laird Thermal Systems, and Ferrotec Corporation.
