Air intake pre-cooling heat exchanger with multiple modes and aircraft
By designing a multi-mode inlet precooling heat exchanger, and utilizing movable and aligned misaligned air vents and heat dissipation fins, the problems of flow resistance and uneven heat exchange effect during low-speed and high-speed flight in existing technologies have been solved, achieving flexible mode switching and temperature uniformity.

Abstract
The application discloses an air intake pre-cooling heat exchanger with multiple modes and an aircraft, wherein the air intake pre-cooling heat exchanger comprises a first radiator and a second radiator; the first radiator comprises at least two first radiating components, and a first air passing hole is arranged between adjacent first radiating components; the second radiator comprises at least two second radiating components, and a second air passing hole is arranged between adjacent second radiating components; the first radiator and the second radiator can relatively move, and at least two modes exist between the first radiator and the second radiator, i.e., a first mode in which the first air passing hole is aligned with the second air passing hole, and a second mode in which the first air passing hole is aligned or partially aligned with the second radiating component, and the second air passing hole is aligned or partially aligned with the first radiating component. According to the requirement of different flight speeds of the engine, the application can conveniently switch between the two modes of "low heat exchange / low flow resistance" and "high heat exchange / high flow resistance".
