Description

TECHNICAL FIELD

[0003] The existing high temperature environment fan does not have high efficient heat dissipation function, for example, the announcement number for CN213870361U discloses a smoke exhaust fire fighting fan for high temperature environment, although the heat insulation layer can be fixed on the surface of the air duct through the cooperation of the fixed screw hole and the No. 3 screw in this patent, the heat insulation layer can block the heat from entering the inside of the air duct after being fixed on the surface of the air duct, thereby protecting the driving motor inside the air duct, but the heat insulation layer also limits the dissipation of the heat inside the air duct, especially the driving motor, which generates a large amount of heat during the working process. Due to the existence of the heat insulation layer, a relatively closed space is formed inside the air duct, and the heat generated by the driving motor is difficult to be discharged through natural convection or radiation, and after a long time of work, the heat will accumulate inside the air duct, resulting in the temperature rise of the motor, which may even exceed its normal working temperature range.
