Abstract
The utility model discloses a magnetic fan, wherein a rotating shaft is driven in rotation motion by a motor; and in the rotation process, a first magnetic element fixed on the rotating shaft generates attraction or repelling action on a second magnetic element periodically. As the second magnetic element is fixed with fan blades and the first ends of the fan blades are fixed on a base, the fan blades swing under the periodic action of the attraction force and the repelling force so as to generate wind. The fan blades of the magnetic fan mainly swing periodically, so that the space occupied by the fan blades can be effectively controlled; and the thickness of the magnetic fan may be similar to that of the portable electronic equipment, so that the space arrangement of the electronic equipment can be further optimized.
Description
Technical field
The utility model relates to a kind of magnetic fan, the particularly flabellum of described magnetic fan and produces uniform air flow by swinging.
Background technique
In the prior art, radiation fan comprises the flabellum of motor and connection and motor output shaft at least, and under the driving of described motor, described flabellum rotation produces axial flow wind, and then realizes the heat radiation to the target electronic components and parts.Because fan must provide enough spaces, can do complete axial motion to guarantee described flabellum, in other words, the width that holds the space of fan is the twice of flabellum length at least.This does not obviously meet the user to the requirement of electronics miniaturization.In addition, if when providing cooling blast with the larger fan of volume, the volume of super removable computer is increased, its noise that produces when rotating, its power consumption with and the even flow field degree of the cooling blast that provided all can't reach the requirement of super removable computer.Therefore, necessary research and development are more frivolous, space hold is less, and the fan of the better cooling blast of even flow field degree can be provided.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of magnetic fan, can reduce space hold, the problem that exists to solve prior art.
For solving the problems of the technologies described above, the utility model adopts following technical proposals.
A kind of magnetic fan is characterized in that, comprising:
Pedestal, described pedestal has the inner chamber of at least one;
Motor, described motor are arranged in the described pedestal, and the output shaft of described motor is connected with a rotating shaft, and described rotating shaft extends in the described inner chamber, and are fixed with the first magnetic element in the described rotating shaft;
The flabellum of at least one, described flabellum is arranged in described inner chamber, and an end of described flabellum is rotatably connected on the described pedestal, and described flabellum is being provided with the second magnetic element for position that should described the first magnetic element.
In technique scheme, described rotating shaft rotates under the driving of motor, and in rotation process, the first magnetic element that is fixed in the described rotating shaft periodically produces attraction or repulsive interaction to described the second magnetic element.Because the second magnetic element and described flabellum are fixed together, and an end of flabellum is fixed on the described pedestal, thus described flabellum at the period effects lower swing of attraction force and repulsive force, and then generation wind.
Concerning volume and lower-powered electronic product, its inner electronic component does not need a large amount of cooling blasts to reach heat exchange heat radiation, does not flow so that internal heat is hoarded as long as prevent air, causes that the casing surface temperature is too high to be got final product.And this magnetic fan of the present utility model can reach such purpose just.
In this magnetic fan of the present utility model, described the first magnetic element is vertical with described rotating shaft with the axis that described the second magnetic element limits.In this preferred version, described the first magnetic element and the second magnetic element are corresponding to be arranged, can improve the action effect between the magnetic element, and then improve working efficiency of the present utility model.
In this magnetic fan of the present utility model, the number of described flabellum is even number, and described flabellum is divided into two parts of both sides that lay respectively at described rotating shaft that number equates.Described flabellum is divided into two parts of both sides that lay respectively at described rotating shaft that number equates, therefore, the uniformity coefficient of air-flow can be further enhanced.
Implement this magnetic fan of the present utility model, have following beneficial effect: described flabellum of the present utility model is mainly done periodically and is swung, therefore can effectively control the space that it takies, and the thickness of described magnetic fan can be similar to portable electric appts, can further optimize the space of electronic equipment and arrange.
Description of drawings
Fig. 1 is the schematic representation of this magnetic fan of the present utility model;
Fig. 2 is the partial view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Of the present utility model this magnetic fan shown in Fig. 1 to 2 is characterized in that, comprising: pedestal 1, and described pedestal 1 has the inner chamber 101 of at least one; Motor 2, described motor 2 is arranged in the described pedestal 1, and the output shaft of described motor 2 is connected with rotating shaft 201, and described rotating shaft 201 extends in the described inner chamber 101, and is fixed with the first magnetic element 301 in the described rotating shaft 201; The flabellum 4 of at least one, described flabellum 4 is arranged in described inner chamber 101, and an end of described flabellum 4 is rotatably connected on the described pedestal 1, and described flabellum 4 is being provided with the second magnetic element 302 for position that should described the first magnetic element 301.
In this magnetic fan of the present utility model, the axis that described the first magnetic element 301 and described the second magnetic element 302 limit is vertical with described rotating shaft 201.The magnetic pole of described the first magnetic element 301 is mutually corresponding with the magnetic pole of described the second magnetic element 302, and is maximum to guarantee the active force between the magnetic pole.
In this magnetic fan of the present utility model, the number of described flabellum 4 is even number, and described flabellum 4 is divided into two parts of both sides that lay respectively at described rotating shaft 201 that number equates.As shown in Figure 1, described flabellum 4 is divided into number and is two groups of three, and is divided into the both sides of described rotating shaft 201, and wherein, come in flabellum 4 spaces of homonymy.
