Abstract
The utility model relates to a heat radiating fan, particularly to a fan of a power generator, which comprises a fan chassis; the center of the fan chassis is provided with a boss; the center of the boss is provided with a shaft hole; fixed holes are arranged around the shaft hole; 20 vertically mounted blades are uniformly arranged on the four sides of the chassis surface of the fan chassis; the diameter phi of the fan chassis is 173mm; the head ends and the tail ends of the blades are arranged along a radius radiation direction of the fan chassis; blade section central segments connected with the head ends and the tail ends of the blades are arc linear segments; and the radius R of the arc segment is 18mm. The fan of power generator using this technical scheme can increase wind power and improve heat radiating effect.
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.
The fan of this conventional construction, though can, because the air blade plate shape is a circular arc, wind-force is little, it is not fine causing radiating effect.
The model utility content
The technical problem that the utility model will solve provides a kind of wind-force that adds big fan, the Power generator fan of good heat dissipation effect.
In order to solve the problems of the technologies described above, the utility model provides a kind of Power generator fan, the fan chassis that includes; The central authorities on described fan chassis are provided with boss; Described boss central authorities are provided with axis hole, are provided with fixed hole around the described axis hole, 20 blades of vertically installing of evenly arranging on around the card on said fan chassis; The diameter of phi on said fan chassis is 173mm; 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 circular arc adds straightway, and the radius R of arc section is 18mm.
Adopt the Power generator fan of technique scheme to have following advantage, 1, because fan blade has adopted circular arc to add the blade shape of straightway, than traditional arc shaped blade, its wind-force is bigger, radiating effect is better.
As preferred version, consider simultaneously since fan 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, and the bolt joint may be asynchronous and loosening because of expanding, and produces vibration when causing fan to rotate; Influence radiating effect; Therefore limiting described fixed hole is provided with three, is evenly distributed on around the axis hole, is provided with metal insert in the fixed hole.
As preferred version,, be provided with five 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 blade shape schematic representation 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, the fan chassis 1 that includes; The central authorities on fan chassis 1 are provided with boss 2; Boss 2 central authorities are provided with axis hole 3, evenly are provided with three fixed holes 4 around the axis hole 3, are provided with metal insert in the fixed hole 4; 20 blades of vertically installing 6 of evenly arranging on around the card on fan chassis 1; The diameter of phi on fan chassis 1 is 173mm, arranges along the radius radiation direction on fan chassis 1 in the head and the tail two ends of blade 6, and the leaf cross-section center line segment that connects blade 6 head and the tail two ends is that circular arc adds straightway; The radius R of arc section is 18mm, is provided with five on the fan chassis 1 that blade is 6 uniformly and strengthens gusset 7
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.
Claims (3)
1. Power generator fan; It is characterized in that: the fan chassis that includes, the central authorities on described fan chassis are provided with boss, and described boss central authorities are provided with axis hole; Be provided with fixed hole around the described axis hole; 20 blades of vertically installing of evenly arranging on around the card on said fan chassis, the diameter of phi on said fan chassis is 173mm, 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 circular arc adds straightway, and the radius R of arc section is 18mm.
2. Power generator fan according to claim 1 is characterized in that: described fixed hole is provided with three, is evenly distributed on around the axis hole, is provided with metal insert in the fixed hole.
3. Power generator fan according to claim 1 is characterized in that: be provided with five on the said interlobate fan chassis uniformly and strengthen gusset.
