Abstract
The invention discloses a direct-current fan of a structure of fixing a stator through a metal clamping piece. The direct-current fan of the structure of fixing the stator through the metal clamping piece is composed of a shell, a rotor assembly, the stator, a spring, a circuit board, a bearing, a shaft elastic check ring and a soft plug cover. The rotor assembly is supported in the shell through the bearing, and the stator and the circuit board are electrically connected. The direct-current fan of the structure of fixing the stator through the metal clamping piece is a single-phase permanent magnetic direct-current fan and is simple in structure, the structure of fixing the stator through the metal clamping piece is adopted, and an electronic circuit is used for reversing. The direct-current fan is used for heat radiation of power sources and the like, is small in size, light, high in environment resisting capacity, excellent in mechanical resisting environment and good in popularization performance, can be arranged on various electrical devices needing ventilation and heat radiation, and has quite wide market prospects.
Description
Technical field
The present invention relates to structural design and the applied technical field of DC fan, specifically provide a kind of DC fan of Metallic card fixed stator structure.
Background technique
Existing plastic casing be DC fan mainly with bonding mode fixed stator, this kind of structure is along with the accumulation of time, and adhesive glue easily lost efficacy, poor reliability, and environmental resistance is poor.With the DC fan structure of metal card chip, axial restraint stator, prevents stator from giving prominence to, increases Fan Product reliability.People urgently wish the DC fan obtaining the excellent Metallic card fixed stator structure of a kind of technique effect.
Summary of the invention
The object of this invention is to provide the DC fan of the excellent Metallic card fixed stator structure of a kind of technique effect.
The DC fan of described Metallic card fixed stator structure is constructed as follows: housing 1, rotor assembly 2, stator 3, spring 4, circuit board 5, bearing 6, circlip for shaft 7 and cork lid 8; Rotor assembly 2 is supported in housing 1 by bearing 6, described stator 3 forms with circuit board 5 and is electrically connected, spring 4 is enclosed within rotor assembly 2 and is connected with bearing, for ensureing the axial clearance of blower fan, rotor assembly 2 was gone here and there after bearing and was blocked by circlip for shaft 7, prevent rotor assembly 2 from deviating from, cork lid 8 is fitted in the middle of housing 1, plays seal action.Described stator 3 comprises Metallic card 9, winding 10, upper dististyle 11, stator punching group 12 and lower end-piece 13, described Metallic card 9 is arranged between stator punching group 12 and upper dististyle 11, Metallic card 9 is provided with claw 14, claw 14 is stuck in housing 1, prevent stator rotation and protrusion, play the effect of fixed stator.Structure is simple, and soundness is good.Winding 10 is wrapped in stator punching group 12, and stator punching group 12 is between upper dististyle 11 and lower end-piece 13.
The quantity of described claw 14 is 12, is evenly distributed on metal claw 9 inner ring circumferentially, and the shape of described claw 14 is equilateral triangle.This structural strength is high, and after being press fit into housing, firm performance is good.
DC fan belongs to DC permanent-magnetic brushless blower fan, two phase winding alternate conduction during work, thus under the magnetic field that it excites and rotor permanent magnet effect, produce the electromagnetic torque of constant direction, makes rotor turns, rotor driven blade, produces air flowing.
The DC fan of described Metallic card fixed stator structure belongs to single-phase permanent brushless DC fan, and structure is simple, and applied metal card fixed stator structure, utilizes electronic circuit to commutate.Realize blower fan to continue to rotate, there is Wind Volume, be not less than 170m
3/ h, lightweight, not higher than features such as 192g, and environmental resistance is good, can in the rugged environment such as vibration, damp and hot, salt fog, mould reliable operation, mechanical environment is excellent.For the heat radiation of power supply etc., volume is little, lightweight, and resistance to environment capacity is strong, and mechanical environment is excellent, and generalization is good, and can be installed on variously needs on the electrical equipment of ventilation and heat, has boundless market prospects.
