A lug boss is arranged in the center of a chassis of the fan, an axle hole is arranged in the center of the lug boss, clamping and fixing devices are arranged at the periphery of the axle hole, 19 pieces of vertically installed blades are uniformly distributed at the periphery of the chassis surface of the chassis of the fan, the diameter Phi of the chassis of the fan is 149mm, the head ends and the tail ends of the blades are distributed in the radiating direction of the semidiameter of the chassis of the fan, a center line segment of a cross section of the blade connecting the head end and the tail end of the blades is a straight line segment plus an arc segment, the length L of the straight line segment is 25mm, and the semidiameter R of the arc segment is 15.66mm. With the adoption of the electric generator fan of the technical scheme of the utility model, wind force of the fan can be increased, the connection tightness of the fan can be improved, and the heat-conductive effect can be improved.
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.
When using the fan heat radiation of above-mentioned conventional construction, also there are this some following problems: 1, because fan blade is shaped as single circular arc, wind-force is little, it is not fine causing radiating effect; 2, because fan is near thermal source, particularly rotor main shaft conducts to the generator internal heat retainer ring of fan; 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 produces vibration when causing fan to rotate, and influences radiating effect; 3, because the blade height of fan center is higher relatively, produce turbulent flow when causing fan to rotate, influence radiating effect.
The model utility content
The technical problem that the utility model will solve provides a kind of fan wind-force that strengthens, and improves fan and connects tightness, improves turbulent situation, improves the Power generator fan of heat-conducting effect.
In order to solve the problems of the technologies described above, the utility model provides a kind of Power generator fan, includes the fan chassis; The central authorities on described fan chassis are provided with boss, and described boss central authorities are provided with axis hole, are provided with fixed hole around the described axis hole; Described fixed hole is provided with the inserts that matches with fixing bolt; 18 blades of vertically installing of evenly arranging on around the card on said fan chassis, the diameter of phi on said fan chassis is 166.5mm, arrange along the radius radiation direction on fan chassis in the head and the tail two ends of said blade; The leaf cross-section center line segment that connects blade head and the tail two ends is that straightway adds arc section; The two ends spacing L of center line segment is 48.55mm, and the radius R of arc section is 17mm, and the corresponding blades height of said straightway is lower than the corresponding blades height of arc section.
Adopt the Power generator fan of technique scheme to have following advantage, 1 since the employing of fan blade straightway add the shape of arc section, than traditional arc shaped blade, its wind-force is bigger; 2, because fixed hole is provided with the inserts that matches with fixing bolt, than the conventional plastic fan, the ability of its opposing thermal expansion is stronger, has therefore improved the compact type that connects, good heat conduction effect; 3, because the corresponding blades height of straightway is lower than the corresponding blades height of arc section, the turbulent situation in center portion improves like this.
As preferred version, consider stressed symmetry properties and the convenience that is connected, described fixed hole is provided with two, is symmetrically distributed in around the axis hole, and described fixed hole is provided with the inserts that matches with fixing bolt.
As preferred version,, be provided with six on the said interlobate fan chassis uniformly and strengthen gusset in order further to improve the intensity of fan.
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 structural representation of looking up of the utility model Power generator fan;
Fig. 3 is the structural representation of the utility model Power generator fan blade.
Embodiment
Like Fig. 1, shown in 2 and 3, the utility model provides a kind of Power generator fan, includes fan chassis 1; The central authorities on fan chassis 1 are provided with boss 2, and boss 2 central authorities are provided with axis hole 3, are symmetrically arranged with two fixed holes 4 around the axis hole 3; Fixed hole 4 is provided with the inserts that matches with fixing bolt; 18 blades of vertically installing 5 of evenly arranging on around the card on fan chassis 1, the diameter of phi on fan chassis 1 is 166.5mm, arrange along the radius radiation direction on fan chassis in the head and the tail two ends of blade 5; The leaf cross-section center line segment that connects blade 5 head and the tail two ends is that straightway adds arc section; The two ends spacing L of center line segment is 48.55mm, and the radius R of arc section is that the corresponding blades height of 17mm straightway is lower than the corresponding blades height of arc section, is provided with six on the fan chassis 1 that blade is 5 uniformly and strengthens gusset 6.
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.
