Peltier Cooler

Use a Peltier Cooler simulation object to model solid state heat pumps. Peltier coolers are also known as Thermo Electric Coolers (TEC).

• Peltier coolers or TECs serve the same cooling functions as mechanical refrigeration systems. In these devices, thermal energy is extracted from one region to cool it and exhausted to another region, typically the environment. However, Peltier coolers use a solid state thermocouple (p-n) rather than mechanical parts.

• During operation, current flows through the TEC to create heat transfer. A temperature differential is generated across sets of semiconducting couples held between insulating ceramic plates. This causes one side of the TEC to be cold and the other one to be hot.

The software calculates Peltier heat loads as well as heat loads resulting from Joule heating and conductive heat flow between the plates.

• (A) Electronic component

• (B) Thermal interface between the electronic component and the TEC

• (C) Cold side insulating plate

• (D) Hot plate insulating plate

• (E) p-n semiconducting couples

To create a Peltier cooler, you specify:

• A set of cold plate elements and a set of hot plate elements.

• The electrical resistivity and thermal conductivity of the semiconductor material.

• The geometrical factor representing the area to length ratio of each thermocouple element.

• A positive or negative voltage or current.

• The number of p-n thermocouples.

• The system Seebeck coefficient.The system Seebeck coefficient is the absolute sum of the p and n couple Seebeck coefficients.Example: Some TECs are made of bismuth telluride (Bi2Te3) with Seebeck coefficients of –280 μV/ °C for the n-type couplings and 80 μV/ °C for the p-type couplings. The system Seebeck coefficient is then 200 μV/ °C.

Note:

Values for defining a Peltier cooler boundary condition can be obtained from the device manufacturer and should be verified for applicability.
