Abstract
The utility model relates to a cooling fan, in particular to a cooling fan of a generator. The fan comprises a round fan base plate and a metal insert used for fixing the fan, wherein a boss is arranged at the center of the fan base plate, the metal insert is fixed at the center of the boss, a shaft hole is arranged at the center of the metal insert, fixing holes are arranged around the shaft hole, fifteen vertically arranged straight blades are evenly distributed on the plane edge of the base plate of the fan, the diameter Phi of the fan base plate is 134mm, one edge of each straight blade, close to the shaft hole, inclines towards the shaft hole, the length L of each straight blade is 20mm, and the height H of each straight blade is 19mm. By adopting the technical scheme, the fan of the generator can increase the wind force, and is firm in connection, small in noise and simple in machining.
Description
Technical field
The utility model relates to a kind of radiation fan, relates in particular to a kind of radiation fan of generator.
Background technique
Generator is a kind of common dynamic power machine; Be provided with skeleton in the generator; The line bag is installed on the skeleton generating an electromagnetic field, and during powerful generator work, line bag heating value is very big; When temperature is too high, can influence the proper functioning of generator, therefore need the sink that radiating effect is good.At present the most frequently used sink is a fan, and the main shaft of generator amature is extended out, and installs Power generator fan.For the ease of making; Common Power generator fan adopts the plastic construction once-through more, and the air blade sheet is fixed on the card of fan chassis; The blade of fan adopts arc structure; Drive the fan rotation when alternator shaft rotates and produce air-flow, the heat that produces in the generator work is discharged, to reach heat radiation.
Use the radiation fan of this conventional construction,, still exist some problems in the actual using process though have certain radiating effect: 1, because fan blade is shaped as circular arc, wind-force is little, it is not fine causing radiating effect; 2; Simultaneously since fan near thermal source, particularly rotor main shaft conducts to the retainer ring of fan with the generator internal heat, the thermal expansion coefficient of plastic material is greater than the thermal expansion coefficient of metal rotating shaft; The bolt joint is asynchronous and loosening because of expanding, and causes loosening vibrating noise bigger; 3, the circular arc vane processed complex.
The model utility content
The technical problem that the utility model will solve provides a kind of wind-force that adds big fan, connection is fastening, noise is little and process simple Power generator fan.
In order to solve the problems of the technologies described above, the utility model provides a kind of Power generator fan, includes circular fan chassis and in order to the metal insert of fan attachment; The central authorities on described fan chassis are provided with boss, and described metal insert is fixed on boss central authorities, and described metal insert central authorities are provided with axis hole; Be provided with fixed hole around the described axis hole; Said fan along evenly being placed with 15 prismatic blades of vertically installing on the card edge, chassis, the diameter of phi on said fan chassis is 134mm, one side said prismatic blade is near the axis hole that is tilted to of axis hole; Prismatic blade length is 20mm, and straight-vaned height is 19mm.
Adopt the Power generator fan of technique scheme to have following advantage, 1 because fan has adopted prismatic blade, one side prismatic blade near the axis hole that is tilted to of axis hole, than traditional arc shaped blade, its wind-force is bigger, radiating effect is better; 2, because boss central authorities are provided with metal insert, are affixed on the motor shaft through metal insert, its expanded by heating influence is less, therefore connects fasteningly, and noise is less; 3, than the blade of circular arc, prismatic blade processing is also more convenient.
As preferred version, consider the actual demand of fixed hole and stressed symmetry properties, described fixed hole is provided with eight, is evenly distributed on around the axis hole.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model Power generator fan;
Fig. 2 is the plan structure schematic representation of the utility model Power generator fan;
Fig. 3 is the metal insert cross-sectional view of the utility model Power generator fan.
Embodiment
Like Fig. 1, shown in 2 and 3, the utility model provides a kind of Power generator fan, includes circular fan chassis 1 and in order to the metal insert 2 of fan attachment; The central authorities on fan chassis 1 are provided with boss 3, and metal insert 2 is fixed on boss central authorities 3, and metal insert 2 central authorities are provided with axis hole 4; Be provided with the fixed hole 5 that fixing bolt matches around the axis hole 4; Along evenly being placed with 15 prismatic blades of vertically installing 6 on the card edge, chassis, the diameter of phi on fan chassis 1 is 134mm, one side prismatic blade is tilted to axis hole 4 near axis hole 4; Prismatic blade 6 length are 20mm, and the height of prismatic blade 6 is 19mm.Fixed hole 5 is provided with eight, is evenly distributed on around the axis hole 4.
Above-described only is the preferred implementation of the utility model; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
