The paper presents results of numerical fmite volume analysis of an efficiency of honeycomb compact gas to gas heat exchanger usedfor compressor interstage cooling for aircraft jet engine. The main analysis starts with building geometry followed by the problem description and model discretization leading to the flnal results and summary. Eight cases were created for the basic model and also several more for afinned geometry. The parallel and counter-current flow modes were considered Special emphasis was laid on finding the heat transfer rate, LMTD parameter and temperature distribution. It was found out that a honeycomb structure is almost insensitive for flow arrangement change and that afinned structure assures much higher heat transfer rate. The honeycomb structure is almost insensitive for flow arrangement change while the finned structure turned out to provide a much better heat transfer. The structure is also almost insensitive for a more efficient (i. e. parabolic) fin shape could also increase the heat transfer in the required area. A more accurate mesh should be created to analyse the finned structure and get more reliable results. The honeycomb structure provides apossibility to create the heat transfer process between more then two fluids i. e. three or four.
