How to Select a Peltier Module

Sponsored By CUI Devices


Common thermal management solutions used in electronics applications address cooling objects with heat exchangers and fluid flow. The heat exchanger is typically either the electronic package itself or an extruded or stamped heat sink attached to the package. Air is the most common fluid used in thermal solutions, either with natural convection or propelled by a fan. In most of these solutions the temperature of the object being cooled remains above the ambient temperature. Peltier modules are electronic devices designed for cooling objects to below the ambient temperature or maintaining objects at a specific temperature by controlled heating or cooling. Selecting or specifying a Peltier module is not difficult but a basic understanding of module characteristics can be helpful to ensure the process flows smoothly.

In the CUI Devices video above, learn more about the different types of Peltier devices, how to read performance graphs on a Peltier module datasheet, and how to specify the proper thermoelectric cooler for your intended application.
