▎ 摘　　要

NOVELTY - The structure has a stator (20) which is configured inside a motor housing (10). A rotor shaft (30) is rotatably configured in the center of the stator. A cooling fin (40) for heat dissipation is provided on the outside of the stator. An impeller (50) for blowing is connected to one side of the rotor shaft. A back plate (60) is coupled to the rear end of the motor housing. A first inlet through hole (11) and a second inlet through hole (12) are formed in two rows to introduce external air. The cooling fin is introduced through the first and second inlet through holes at one side of the cooling fin. A blocking wall (41) is provided for forming an individual flow path of the cooled air is integrally provided. The blocking wall has a close contact insulating layer for preventing a gap with the inner wall surface of the motor housing and improving thermal insulation. An adhesion insulating layer is metallocene polyethylene, epoxy resin, glass wool, graphene powder, rhenium oxide. USE - Cooling structure of turbo blower. ADVANTAGE - The cooling efficiency of the turbo blower is improved. The production cost and power consumption are reduced. The motor cooling efficiency is increased since there is no additional heat transfer to the motor housing portion due to the discharge temperature of high heat generated from the turbo fan impeller. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional structural view of the turbo blower. 10Motor housing 11First inlet through hole 12Second inlet through hole 20Stator 30Rotor shaft 40Cooling fin 41Blocking wall 50Impeller 60Back plate
