The invention discloses an automobile air conditioner evaporator drainage structure which comprises an evaporator shell, a drainage cavity is formed in the evaporator shell, a drainage hole is formed in the bottom of the drainage cavity, a step structure is arranged in the evaporator shell, a drainage channel is formed in the step structure, the drainage channel is arranged in an inclined mode, and the drainage hole is communicated with the drainage cavity. The lower end of the drainage channel is connected to the drainage cavity, the drainage channel is provided with a first side wall and a second side wall, a first flow deflector is arranged on the first side wall, a second flow deflector is arranged on the second side wall, the first flow deflector and the second flow deflector are obliquely arranged in the drainage channel, and the first flow deflector and the second flow deflector are arranged between the first flow deflector and the second side wall. And water passing gaps are formed between the second flow deflectors and the first side wall. The air conditioner has the beneficial effects that the air volume loss can be reduced, the refrigeration efficiency is improved, whistling sound is avoided, positive pressure drainage can be formed, and it is guaranteed that condensate water is discharged out of the evaporator timely and efficiently.
