The invention discloses an air guide device for a vehicle engine compartment. The air guide device is characterized by comprising an engine compartment engine cover and an inner engine cover which is arranged in the engine compartment engine cover, wherein corresponding rear openings and side openings are formed in the tail end and the two sides of the engine compartment engine cover respectively; a middle plate is arranged between the engine compartment engine cover and the inner engine cover and used for dividing the rear openings into upper and lower parts; side plates are further arranged at the two sides of the middle plate respectively; two side outlets are formed between the two side plates and the engine compartment engine cover, and between the inner engine cover and the two side openings. Through different hot air flowing channels, air flow direction in the engine compartment is guided by utilizing fluid characteristics of hot air, so that hot air flows out of the engine compartment through a built runner, air temperature in the engine compartment is reduced, the hot air is prevented from flowing back into the engine compartment, the working stability of the engine is guaranteed, and the working performance of the radiator is improved.
