FINE TUBULAR TYPE HEAT EXCHANGER FOR GAS TURBINE ENGINE AND THE MANUFACTURING METHOD OF IT

摘要

PURPOSE: A fine tubular type heat exchanger for a gas turbine engine is provided to reduce the weight of a heat exchanger and increase heat exchange efficiency. CONSTITUTION: A fine tubular type heat exchanger for a gas turbine engine comprises an inflow tube(10), an outflow tube(20), and multiple heat exchanging tubes(30). The air of high pressure and high temperature flows into the inflow tube. The outflow tube is placed side by side with the inflow tube. The multiple heat exchanging tubes are connected to the inflow tube and the outflow tube so that the air can flow from the inflow tube to the outflow tube.
