Aerospace Instrument-Making Annotation << Back Parameters optimization of primary heat exchanger for aircraft air-conditioning systems A.V. Chichindaev, I.G. Diominov We study the heat-stressed condition of the primary heat exchanger (PHE) of AСS. We describe the characteristic of exploitational features and examples of destruction of PHE. We present the algorithm of calculation of fields of temperatures and thermal stresses of PHE. We describe the resuits of researches of influencing of design of the compact heat exchanger on activity of PHE. We made the conclusions about influencing the investigated factors on a heat-stressed condition of PHE in summary. Key words: Heat exchanger, air-conditioning systems, computer simulation, thermal stresses, parameters optimization. E-mail: ttf_nstu@rambler.ru
