The master's work presents the process of strength analysis of a plate-type heat exchanger. In order to carry out a numerical calculation using the finite element method (FEM), it is necessary to obtain a 3D model of the heat exchanger. The model of the plate-type heat exchanger was obtained by scanning or 3D computed tomography. Based on the obtained geometry by scanning, it was necessary to correct it accordingly, so that it could then be used for numerical calculation (numerical 3D model). The geometry was parameterized, which allowed us to perform parametric simulations (monitoring different responses depending on the input geometry). In the numerical calculation, we dealt with load cases of vented and non-vented places in the heat exchanger and, consequently, with different stress-deformation states and their influence on the expected lifetime of the heat exchanger. Numerical calculations (FEM) were carried out in the Ansys Workbench software package, whereby the obtained results
