Abstract
The utility model relates to a radiating fan, which particularly comprises a fan chassis. A shaft hole is arranged in the center of the fan chassis, two cylindrical fixing holes are symmetrically arranged on two sides of the shaft hole, 18 vanes which are vertically installed are evenly distributed on the periphery of the chassis face of the fan chassis, the diameter phi of the fan chassis is 155.45mm, the front end and the tail end of the vanes are distributed along the radius radiation direction of the fan chassis, the radius R of a circular segment which connects center line segments of cross sections of the vanes at the front end and the tail end of the vanes is 31.75mm. By means of the technical scheme, the generator fan is tight in connection, low in noise and good in 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.
When using the fan heat radiation of above-mentioned conventional construction; Because fan is near thermal source, particularly rotor main shaft conducts to the retainer ring of fan with the generator internal heat, and 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; Produce vibration when causing fan to rotate, not only noise is big, and influences radiating effect.
The model utility content
The technical problem that the utility model will solve provide a kind of fan connect fastening, noise is little, 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, includes the fan chassis, and the central authorities on described fan chassis are provided with axis hole; The bilateral symmetry of axis hole is provided with two column fixed holes; 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 155.45mm, arrange along the radius radiation direction on fan chassis in the head and the tail two ends of said blade; Connect the leaf cross-section center line segment arc section at blade head and the tail two ends, the radius R of arc section is 31.75mm.
Adopt the Power generator fan of technique scheme to have following advantage, 1, owing to adopted the fixed hole of two columns; The column fixed hole is very elongated, than the Placement that traditional clamping bolt passes attachment hole, behind its fan; Axially expanding more of column fixed hole makes and fastening better effects if therefore improved the compact type that connects; The fan vibrations are little, so noise is little, good heat dissipation effect.
As preferred version, in order further to increase the bulk strength of fan, described fan chassis evenly is provided with six stiffening ribs of radially radiation near the part of 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.
Embodiment
As shown in Figure 1; The utility model provides a kind of Power generator fan, includes fan chassis 1, and the central authorities on fan chassis 1 are provided with axis hole 2; The bilateral symmetry of axis hole 2 is provided with the column fixed hole 3 of two connection clamping bolts; 18 blades of vertically installing 4 of evenly arranging on around the card on fan chassis 1, the diameter of phi on fan chassis 1 is 155.45mm, arrange along the radius radiation direction on fan chassis in the head and the tail two ends of blade 4; Connect the leaf cross-section center line segment arc section at blade 4 head and the tail two ends, the radius R of arc section is 31.75mm.Fan chassis 1 evenly is provided with six stiffening ribs 5 of radially radiation near the part of axis hole 2.
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 (2)
