Compound defroster of multichannel formula

The utility model discloses a compound defroster of multichannel formula, including defroster casing, the axial setting tubular structure by baffling hoarding one-tenth in the defroster casing, inside filler room and the middle rectification room of divideing into of this tubular structure, be equipped with second, third baffling board between the upper and lower tip of tubular structure and the defroster casing, be equipped with the backup pad between the middle part of tubular structure outer wall and the defroster casing, cavity formation bottom volute chamber between second baffling board and the backup pad, cavity formation top volute chamber between backup pad and the third baffling board, the air current at first gets into bottom volute chamber, middle rectification room, filler room and top volute chamber by the bottom of defroster casing in proper order, is discharged by the top of defroster casing again. The compound defogging that utilizes multichannel separation, the separation of baffling board inertia and the separation of packing to combine together acts on for less liquid drop is further got rid of, thereby makes solution chimney that this defroster can be better rain or the phenomenon of rainy gypsum.
