Abstract
The utility model provide a self-radiation fan blade for a fan, which comprises a rotor, a blade and a wheel hub; wherein the bottom of the wheel hub is uniformly distributed with a plurality of column pipes running through the bottom of the wheel hub, the top of the column pipe is the slanting section, the included angle between the intersection line between the slanting section and the wheel hub bottom surface and the wheel hub diameter is less than 45 degrees, and the orientation of the slanting section and the rotation of the fan blade are in the same direction. When the fan works, the air runs through the column pipe in order to take away the heat amount between the stator and the rotor, which effectively reduces the temperature rise of the fan and prolongs the service life of the fan.
Description
Technical field
The utility model belongs to radiation fan, particularly the flabellum of heat radiation certainly of fan.
Background technique
Fan is widely used as the sink of some electrical products or equipment, and the radiating effect of these electrical products or equipment can adopt number of ways to be improved.But, fan this in when work, the heat that its motor stator produces can not get timely eliminating, gathers, also close-fitting rotor is with it given in conduction, the gathering of heat is to producing harmful effect in working life of whole fan.
Summary of the invention
The purpose of this utility model is the problem that solves stator and rotor heat accumulation in the prior art, and a kind of flabellum from heat radiation is provided, the heat that produces when eliminating the heat that rotor gathers and then also eliminating stator work.
Model utility provides a kind of flabellum of heat radiation certainly of fan, it is characterized in that evenly distributing in the bottom of wheel hub, several run through the garden column jecket of wheel hub bottom, column jecket top, garden is an oblique section, the angle that the intersection of oblique section and wheel hub bottom surface intersects with hub diameter is less than 45 °, and the oblique section orientation is rotated same direction with flabellum.When fan work, flabellum rotates, and air also flows, and by being evenly distributed on the garden column jecket of wheel hub bottom, the heat that stator produces is taken away rapidly under the effect of oblique section, reduces the temperature rise of fan stator and rotor effectively, prolongs the working life of fan.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The novel enforcement of this usefulness is very simple, flabellum mainly is made of rotor 1, blade 2, wheel hub 3, when the flabellum moulding, configure the number of garden, wheel hub 3 bottom column jecket 4, simultaneously the top of garden column jecket 4 is pressed into oblique section 5, and making angle that oblique section 5 and wheel hub 3 bottom surface intersections intersect with wheel hub 3 diameters less than 45 °, the flabellum of heat radiation certainly of fan is made like this, by normal operation flabellum and stator pack is dressed up radiation fan then.When fan work, flabellum rotates, and air also flows, under the effect of oblique section, air is taken away the heat of rotor, stator rapidly by being evenly distributed on the garden column jecket of wheel hub bottom, effectively reduces the temperature rise of fan self, prolonged fan working life.
Claims (1)
1, the flabellum of heat radiation certainly of fan, mainly constitute by rotor, blade, wheel hub, it is characterized in that: evenly distributing in the bottom of wheel hub, several run through the garden column jecket of wheel hub bottom, column jecket top, garden is an oblique section, the angle that the intersection of oblique section and wheel hub bottom surface intersects with hub diameter is less than 45 °, and the oblique section orientation is rotated same direction with flabellum.
