Embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Mode is applied to elaborate to the utility model.
As shown in Figure 1 to Figure 3, embodiment of the present utility model discloses a kind of fan, and the fan is used to be arranged on electronics
In order to which heater element radiates in equipment.The fan includes fan body 20, housing 10 and causes what fan body 20 was rotated
Electromagnetic drive component；Fan body 20 is set in the housing 10, and fan body 20 includes impeller 21 and multiple blades 22, Duo Geye
Piece 22 is circumferentially provided on impeller 21；Electromagnetic drive component includes magnet 31 and silicon steel 32, and magnet 31 is fixed on fan body 20
On, silicon steel 32 is fixed on the housing 10, magnet 31 and silicon steel 32 of the present utility model and the magnet in fan of the prior art
31 is identical with the effect of silicon steel 32, i.e., produce galvanomagnetic-effect between magnet 31 and silicon steel 32, so as to drive fan body 20 to rotate.
Key of the present utility model is：Magnet 31 and silicon steel 32 are arranged in the periphery of impeller 21 and wound impeller 21.In this implementation
In example, magnet 31 is specifically arranged on blade 22, and the mode that can be fastened with fastener of magnet 31 or the mode with glue sticking
It is fixedly connected with blade 22.
Understood according to above-mentioned, magnet 31 and silicon steel 32 are arranged in the periphery of impeller 21, and fan of the prior art
Magnet 31 and silicon steel 32 are arranged on the inside of impeller 21, and magnet 31 and silicon steel 32 are arranged in mode inside impeller 21 so that impeller
Need to form sufficiently large space inside 21, the particularly space needs large-size to accommodate the He of magnet 31 in radial directions
Silicon steel 32, this certainly will at least increase the size of impeller 21 in radial directions, so that impeller 21 is in whole fan body 20
In occupied large percentage, occupied compare accordingly, as the blade 22 for the functional part for forming air-flow (or referred to as wind)
Example is smaller, so that fan body 20 is in rotation process, (power consumption will not be changed the power consumption that the partial turn of impeller 21 is consumed
Into air-flow, belonging to idle work) proportion is larger, and therefore, fan power consumption of the prior art is larger.And for the utility model
Fan, magnet 31 and silicon steel 32 is arranged in the periphery of impeller 21, and impeller 21 is not necessarily magnet 31 and silicon steel 32 provides and installs empty
Between, so that impeller 21 is in the small-sized of radial direction, the occupied ratio very little in whole fan body 20, as
Ratio occupied by the blade 22 for the functional part for forming air-flow (or referred to as wind) is very big, so that fan body 20 was being rotated
Cheng Zhong, power consumption (power consumption will not change air-flow, belong to idle work) proportion very little, wind that the partial turn of impeller 21 is consumed
Fan body 20, which rotates almost all, to be used to produce air-flow.In other words, on the premise of identical air quantity is produced, consumption of the present utility model
The power consumption of fan of the prior art can be much smaller than.
Magnet 31 and silicon steel 32 in the fan of the utility model embodiment can be in overall ring-types, or circumferential
Arrangement and 31 pieces of one-to-one multiple magnets and multiple 32 pieces of silicon steel.
Magnet 31 can have two kinds of relative position relations, Yi Zhongshi with silicon steel 32：Magnet 31 is located on the inside of silicon steel 32, and with
Silicon steel 32 is relative；It is another to be located at the outside of silicon steel 32 for magnet 31 and relative with silicon steel 32.Both relative position relations according to
The concrete structure of the housing 10 of fan, particularly fan and select.
It should explain：The relativeness of above-mentioned magnet 31 and silicon steel 32 refers to magnet 31 with silicon steel 32 in fan body 20
It is relative in the radial direction, it is relative in the axial direction without referring to.
To reduce obstruction of the magnet 31 to air-flow as far as possible, magnet 31 is arranged on radial direction of multiple blades 22 relative to impeller 21
The circle that is limited of end on.In this way, fan body 20 is when rotating, blade 22 is diametrically hardly hindered, from
And influence of the magnet 31 to fan body 20 is reduced to the full extent.
As shown in figure 3, with reference to Fig. 2, in a preferred embodiment of the present utility model, housing 10 includes top plate 13, bottom
Plate 12 and coaming plate 11, bottom plate 12 are oppositely arranged with top plate 13, and coaming plate 11 is arranged between bottom plate 12 and top plate 13 to surround appearance
Receive the chamber of fan body 20, be provided with mandrel 24 on bottom plate 12, impeller 21 is installed on mandrel 24, and can be with respect to mandrel 24
Rotate, the air inlet 25 of fan is opened on bottom plate 12 and top plate 13 respectively.Mandrel 24 can either turning as fan body 20
Dynamic center, can rotate bias to fan again and limit.Preferably, impeller 21 is installed on mandrel 24 by bearing 23, axle
It is magnetic bearing to hold 23.It can farthest reduce the friction resistance suffered in rotation process of fan body 20 from magnetic bearing
Power, so as to improve effect of fan.
Embodiment of the present utility model additionally provides a kind of electronic equipment, and the electronic equipment includes above-mentioned fan, due to
Above-mentioned fan is provided with electronic equipment, so that the electric energy consumed during effectively smaller electronic equipment dissipating heat, so that
Electronic equipment is set more to save.Preferably, the electronic equipment includes computer, such as notebook computer.
Above example is only exemplary embodiment of the present utility model, is not used in limitation the utility model, and this practicality is new
The protection domain of type is defined by the claims.Those skilled in the art can be in essence of the present utility model and protection domain
It is interior, various modifications or equivalent substitution are made to the utility model, this modification or equivalent substitution also should be regarded as new in this practicality
In the protection domain of type.
