Zusammenfassung:The utility model relates to the technical field of draught fans, in particular to an efficient heat preservation draught fan with a noise reduction structure, which comprises a supporting base, a driving motor is arranged on the end face of the supporting base, the driving end of the driving motor is connected with a draught fan body, and an air inlet is formed in the center of the face, away from the driving motor, of the draught fan body. According to the heat preservation and noise reduction fan, the heat preservation and noise reduction wall is arranged, the purpose of absorbing noise is achieved through the inorganic foam noise reduction layer, the phenolic resin heat preservation layer and the glass wool board layer are arranged, the heat preservation and noise reduction effect is good, and the heat preservation and noise reduction effect is good. Meanwhile, the silencing layer is arranged at the air outlet, so that secondary sound absorption is achieved, and the problem that heat preservation cannot b
