Thermoelectric Cooler, Lumped Thermal System

Application ID: 75591

Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. The thermoelectric modules are a common application of thermoelectricity in cooling engineering. They consist of several thermoelectric legs sandwiched between two thermally conductive plates, one cold and one hot. The device that needs to be cooled down must be attached to the cold face.

This model covers the basic design of a single-stage thermoelectric cooler, modeled with a three-dimensional finite elements component and a zero-dimensional lumped thermal system. The three-dimensional model serves as a reference and results obtained with both models are compared in order to validate the lumped approach.

This model example illustrates applications of this type that would nominally be built using the following products:
