Automobile dehumidification device

The invention discloses an automobile dehumidification device. The automobile dehumidification device comprises a centrifugal blower, an adsorption type roller dehumidifier and an air outlet which are connected in sequence through air pipes. A quarter of the adsorption type roller dehumidifier is the desorption end, an air condenser is disposed at the desorption end, and the desorption end is connected with an automobile tail gas emission device. Three quarters of the adsorption type roller dehumidifier are the adsorption end. The desorption end and the adsorption end are filled with cyclic adsorption silica gel. The air outlet leads to the inside of an automobile. The automobile dehumidification device is higher in adsorption quantity and rate and larger in energy efficiency ratio and reduces emission of automobile tail gas heat to a great degree.
