The invention relates to the technical field of fans, and discloses a direct-current brushless special fan. The direct-current brushless special fan comprises a fan shell, and a driving assembly and amovable impeller which are arranged in the fan shell, and the special fan further comprises an air guide assembly arranged between the driving assembly and the movable impeller, wherein the air guideassembly comprises a first-stage air guide part and a second-stage air guide part, and the first-stage air guide part and the second-stage air guide part are sequentially assembled in an air inlet direction; the first-stage air guide part comprises first-stage air guide blades which are arranged in arc-shaped bent plate type structures, so that the effects that the resistance to air guide is reduced, and the flow guide air speed is increased are effectively realized; the second-stage air guide part comprises second-stage air guide blades which are arranged in wing-shaped plate structures so that the flow of compressed air in an air guide channel can be effectively improved; and the first-stage air guide blades and the second-stage air guide blades are matched with one another, so that thephenomenon of turbulence or eddy current in the air guide channel is effectively avoided when airflows flow, and the energy utilization rate of the movable impeller during mechanical rotation is further improved.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to a special DC brushless fan. Background technique [0002] In the prior art, the fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. Its movement is driven. Most of the conventional fans are driven by a motor to drive the impeller. [0003] However, in the existing fan structure, for small fans, there are few internal guide structures, so turbulent flow or eddy flow is prone to occur when the air flow is introduced, which affects the normal use of the fan; while for large fans, although Its diversion effect is relatively good, but its overall volume is large, which also affects the scope of use of this type of fan; [0004] Therefore, it is very necessary to propose a fan with small volume, good diversion effect and high energy utilization rate. Contents of the invention [0005] In order to effectively solve the above p...
