Heat exchanger for aircraft gas turbine, has substantially tubular twisting element that is arranged at fuel inlet, and is formed for applying twist on flowing fuel by twisting of twisting element

摘要

The heat exchanger (1) has an oil inlet (2), an oil outlet (3), a fuel inlet (4) and a fuel outlet (5), where a substantially tubular twisting element is arranged at the fuel inlet. The twisting element is formed for applying a twist on the flowing fuel by the twisting of the twisting element. The twisting element is constructed as a separate component. The twisting element has a tubular flow passage, where a twist structure is formed on an inner wall of the tubular flow passage for the application of the twist.
