Laird Technologies released the latest version of the AZTEC thermoelectric module (TEM) simulation software. AZTEC is a user-friendly tool that can speed up product development by running simulations on a TEM and viewing its expected output performance based on a given set of thermal and electrical operating points. The tool is available online now.
AZTEC enables engineers to specify a given set of input variables based on application attributes and the program will select the optimal TEM(s) for trial. The simulation software contains an analysis worksheet, which simulates how the TEM(s) will function under a specific set of operating conditions.
The TEM Selection Tool in AZTEC uses input variables, such as heat load, ambient and control temperatures, input voltage requirement and thermal resistance of hot side heat exchangers to recommend an ideal TEM(s) needed to reach an application’s operating condition. The software has been updated with the latest TEM product offerings from Laird Technologies.
AZTEC also features an Analysis Worksheet Tool, which simulates the expected thermoelectric output parameters based on a given set of thermal and electrical operating points. Output parameters calculated include: the hot and cold side temperatures of the TEM, heat pumped at the cold surface of the TEM, coefficient of performance (COP) and input power requirements. The total hot side heat dissipation is also calculated, as it is beneficial in sizing a proper heat exchanger, which commonly mounts directly onto a TEM.
The Qc Estimating Worksheet within the program calculates an estimate on the heat load for device (spot) or chamber (volume) cooling applications. Computations are made based on input provided by the user such as temperature requirements, volumetric dimensions, insulation thickness, material properties and active heat load.
