Laird Technologies, Inc. recently launched an enhanced version of its online thermoelectric module (TEM) simulation software tool: AZTEC™. AZTEC selects the optimal TEM(s) for trial from a given set of input variables based on application attributes that the user specifies. The program also contains an analysis worksheet, which simulates how the TEM(s) will function under a specific set of operating conditions. The interface offers users several options when selecting TEM parameters. The TEM Selection Tool uses input variables, such as heat load, ambient and control temperatures, input voltage requirement, and thermal resistance of hot side heat exchanger to recommend an ideal TEM(s) needed to reach an application’s operating condition.
