The invention discloses a novel high-speed fan structure which comprises a fan volute, a fan impeller, a motor housing, a motor stator and a motor rotor. The fan volute is installed at the end of oneside of the motor housing; the fan impeller is arranged in the fan volute; the fan impeller is arranged at the end of one side of the outer ring of the motor rotor in a sleeving mode; the motor statoris arranged on the outer side of the middle part of the outer ring of the motor rotor and is arranged in an inner cavity of the motor housing; the gap between the motor rotor and the motor stator is1-10 mm; an air outlet is formed in one side of the fan volute, and an air inlet is formed in the side, away from the fan volute, of the end of the fan structure; the air outlet is formed in one sideof the fan volute; the air inlet is formed in the side away from the fan volute; and air enters from the rear end and enters the volute through the large-gap air path, and the air path passes across the surface of the motor rotor to provide timely and effective cooling for the rotor. Air path heat dissipation is conducted through a stable mechanical structure, and an extra cooling system does notneed to be added, so that the overall size of the draught fan is reduced, and the device is compact in overall layout and easy to assemble and disassemble.
Description
technical field [0001] The invention relates to a high-speed rotary motor structure, more specifically a novel high-speed fan structure. Background technique [0002] The high-speed blower fan in the prior art can produce a large amount of heat in the course of work at present, will cause blower fan overheating and burnt if heat is not dissipated in time. In the traditional fan structure, the air inlet and outlet are set on the same side of the fan volute, and the air enters axially and exits laterally during the working process. However, the problem with this heat dissipation structure is that the heat dissipation position is limited, and it is impossible to dissipate heat to all positions inside the fan in a short time, and it is impossible to control the temperature rise of the fan within a reasonable range, and the pressure from one side of the fan volute is relatively high. Large, affecting the service life of the volute. Contents of the invention [0003] The purpo...
