Seebeck effect and the Peltier effect, which were
studied and described by academician A.F. Ioffe
and his staff.
Thermoelectric phenomena are associated with
mutual transformations between electrical and
thermal processes in metals and semiconductors
[1, 2, 3]. From a technological point of view,
thermoelectric materials are used not only in
automotive
technology,
but
also
in
semiconductor technology, radio electronics and
household devices. Thermoelectric systems (TES)
are used to stabilize and regulate temperatures in
the range from -60°C to +120°C [4, 7, 8]. This
thesis outlines the operating principle of a
thermoelectric module (TEM), defines its main
technological parameters, and also presents a
system for modeling the automatic control of a
thermoelectric object for creating high-quality
automotive electronic devices.

ETHODS
This paper discusses the solution of mathematical
problems in the field of semiconductor physics
such as heat transfer and electrodynamics using
the modeling method. The main task of current
production is to create efficient and reliable
thermoelectric converters that can be used to
generate electrical energy from heat, as well as for
cooling various systems.
The ANSYS software package solves stationary
and nonstationary, linear and nonlinear problems
using the finite element method from such areas
of physics as solid mechanics, fluid and gas
mechanics, heat transfer, and electrodynamics.
Calculations can be carried out in batch or
interactive modes. For batch mode, a program
must first be written using the built-in APDL
(ANSYS Parametric Design Language) and ANSYS
commands [5, 9, 10]. The interactive operating
mode is implemented either using the classic
ANSYS graphical interface or on the Workbench
platform. These shells consist of command menus
and windows. Interactive mode is the main
modeling mode, even batch files are usually
created using interactive mode tools. The FEM
solution of the posed boundary value problem is
carried out by the ANSYS program in three stages:
preprocessing, solution and postprocessing. The
block diagram of the implementation of this
algorithm is presented in Figure 1. At the
preprocessing stage, the basis of a finite element
model of the object under study is created. This
stage includes the following procedures: 1
–
The
physical type of the task is established. 2
–
The
type of finite element is selected depending on the
dimension of the object and its other properties.
3
–
The materials of the object are selected and all
its necessary properties are indicated. 4
–
A
geometric solid 3D model of the object is
constructed. 5
–
The geometric model is divided
into finite elements. When laying out, various grid
parameters can be specified. 6
–
In the case of a
contact problem, contact parameters are
established, the contact model and its
characteristics are determined [11, 12].
The second stage - imposing the necessary
boundary conditions on the model and solving the
problem - consists of three main steps:

. To solve the thermoelectric problem, there is a special type of analysis
in the ANSYS software package - thermoelectric (Figure 2) [6]
Figure 2 – Calculation tree when using thermoelectric analysis [6].
This project tree allows, when specifying one
parameter of boundary conditions and material
properties, to carry out calculations of multiple
models. Moreover, in each subsequent branch
you can separately change any of the parameters:
boundary conditions, mesh size, model geometry,
material parameters. In the tree presented in
Figure 3.2, almost all parameters are related to
the initial model and the calculation is based on
the fact that the geometry of the object is common
for all options. The only difference in this project
is the boundary conditions. When solving a
thermoelectric problem, the following physical
quantities can act as boundary conditions:

temperature;
−
heat flow;
−
convection;
−
liquid cooling.
In this case, the temperature on the plates of
thermoelectric modules was implemented as
boundary conditions. Setting the physical
properties of materials is carried out in the
“Engineering Data” section; for this, standard data
from ANSYS libraries are used, or your own
libraries are created, into which data is entered
either from literary sources or measured
independently. As part of this work, various
material libraries were created.
