Aerospace Instrument-Making Annotation << Back Research of activity of an air-to-liquid heat exchanger of autonomous cooling system A.V. Chichindaev The results of investigation of process of heat transfer in the compact heat exchanger are described in case of air – steam cooling. In the first part, the characteristics of an investigated air-to-liquid heat exchanger performance parameters and model of calculation are given. In the second part, the results of investigation of temperature effect and moisture content of scavenging air on an overall performance of the heat exchanger are adduced. In conclusion, the resume about the mechanism of efficiency increase of process of heat transfer are made.
