Inner duct casing structure with semiconductor control and control method

The invention discloses an inner duct casing structure with semiconductor control and a control method, and belongs to the technical field of turbofan engines. The temperature control structure solves the problem that the temperature control flexibility is poor due to the fact that an existing temperature control structure of a turbofan engine usually adopts an electric heating mode and an engine bleed air heating mode. The air compressor comprises an inner duct casing, an outer duct casing, turbofan blades, a rotor and air compressor blades, the turbofan blades and the air compressor blades are arranged on the rotor, the outer duct casing is arranged on the outer side of the rotor, the inner duct casing is arranged between the outer duct casing and the rotor, the inner duct casing is arranged above the air compressor blades, and the air compressor blades are arranged on the inner duct casing. The inner duct casing comprises a heat conduction fin, an outer side face, a semiconductor chilling plate and an inne
