Optimization of the cooling system of the electronic module

This article deals with the design of a bimetallic (copper-aluminum) brazed radiator, effectively cooling elements of electronic module with high heat flow unevenness. The characteristics of the radiator and the method of constructing the initial (non-optimized) model with allowance for the required constraints are given. With the help of automated tools, a study was made, based on the results, that the last optimization of the constructions was created. The optimization was carried out in two stages. Optimization was carried out in two stages. The first stage consisted in the search for the optimal geometry of the radiator design, where the thicknesses and heights of the ribs and strips played the role of variables. The second stage consisted in the gradual replacement of copper material by aluminum in the radiator model. The general structure of the files of the results of the conducted studies is considered. In detail all the difficulties that the authors encountered in the optimization of the design of the radiator in the CAD environment are described in detail, and the ways to solve them. The main tasks solved with the help of the de-veloped algorithm of optimization are the increase of accuracy, the reduction of labor intensity and the duration of the search for the optimal design, the elimination of the influence of the «human» factor.
