An aircraft heat exchanger system according to an exemplary embodiment of this disclosure, among other possible things includes a first heat exchanger assembly that is disposed in an inlet duct assembly, and a skin heat exchanger assembly is in thermal communication with an outer surface of an aircraft structure. The skin heat exchanger is in fluid communication with the first heat exchanger such that a working fluid is communicated therebetween.

A guidance unit comprises a first pipe part and a second pipe part, an inner space diameter of the second pipe part is smaller than an inner space diameter of the first pipe part, causing a cross-sectional area of a second flow space perpendicular to a pipe axis of the second pipe part smaller than that of a first flow space perpendicular to a pipe axis of the first pipe part; one end of the pipe axis of the second pipe part and one end of the pipe axis of the first pipe part are connected in series with each other and spaced apart from each other by a first angle, so that the second flow space communicates with the first flow space; thereby, a pressure of an external fluid in the second flow space is greater than a pressure of the external fluid in the first flow space.

A flow reactor is structured to increase the overall heat transfer coefficient, which represents the efficiency of heat exchange with respect to a reactive fluid to be treated. This flow reactor is provided with three flow passages, which are a first flow passage, a second flow passage, and a third flow passage which spirally circulate within a space formed between an inner tube and an outer tube. The flow passages are compartmented by an inner heat transfer body and an outer heat transfer bodies. The heat transfer bodies spirally circulate, have a screw-like cross-sectional shape in an axial cross-sectional view, and are assembled in a screw-like configuration. By changing the shapes of a male-thread portion and a female-thread portion, the flow passage area of the first flow passage is changed, the second flow passage and the third flow passage are spirally formed, and heat exchange and reaction take place through the heat transfer bodies.
