Abstract

The invention relates to a radiating fan, which comprises a first magnetic pole and a second magnetic pole with fan blades in the first magnetic pole. The first magnetic pole is provided with a coil. When current flows through the coil, a magnetic field between the first and second magnetic poles generates an acting force to the first magnetic pole through the coil and meanwhile, the first magnetic pole generates a reacting force to the second magnetic pole to drive the fan blades to rotate. The invention further provides a radiator.

Description

Sink
Technical field
The invention relates to a kind of sink, refer to a kind of sink that fan dispels the heat to radiator and radiating efficiency is high that utilizes especially.
Background technique
Along with the output power of electronic components such as central processing unit (CPU) and improving constantly of frequency of okperation, the heat of its corresponding generation is showed increased also, if the heat of untimely its generation of eliminating will cause accumulation of heat to cause that temperature raises, and have a strong impact on the normal operation of electronic component.For this reason, industry is carried out auxiliary heat dissipation at these heat-generating electronic elements mounted on surface one radiators usually, installs a fan simultaneously on radiator additional, to strengthen radiating effect.Traditional radiation fan comprises some flabellums and a motor, and described motor is positioned at the middle part of these flabellums, because that radiation fan does not produce in the residing zone of motor when giving radiator heat-dissipation is distinguished and admirable, makes its radiating efficiency not high.
Summary of the invention
In view of above content, be necessary the sink that provides a kind of radiating efficiency high.
A kind of radiation fan, comprise that one first magnetic pole and is positioned at second magnetic pole that described first magnetic pole is equiped with flabellum, be equiped with coil on described first magnetic pole, when having electric current to flow through in the coil, magnetic field between described first magnetic pole and second magnetic pole produces an active force by described coil to first magnetic pole, thereby described first pole pair, second magnetic pole produces the rotation of reaction force driving flabellum simultaneously.
A kind of sink, comprise radiator and give the radiation fan of described radiator air-supply, described radiator comprise one with treat the base of heat dissipation element thermo-contact, reach the radiating fin that upwards gives off from described base, described radiation fan is installed on the top of radiating fin, it comprises that one first magnetic pole and is positioned at second magnetic pole that described first magnetic pole is equiped with flabellum, be equiped with coil on described first magnetic pole, when having electric current to flow through in the coil, magnetic field between described first magnetic pole and second magnetic pole produces an active force by described coil to first magnetic pole, thereby described first pole pair, second magnetic pole produces the rotation of reaction force driving flabellum simultaneously.
The radiation fan that sink of the present invention adopts flabellum and coil to be separated has saved the motor that is positioned at the flabellum middle part on the traditional heat-dissipating fan, and the border circular areas that makes the entire heat dissipation fan rotate all will produce distinguished and admirable, has improved the radiating efficiency of radiation fan.
Description of drawings
Fig. 1 is the three-dimensional exploded view of sink preferred embodiment of the present invention, and described sink comprises a radiator and a radiation fan.
Fig. 2 is the worm's eye view of the radiation fan of Fig. 1.
Fig. 3 is the three-dimensional assembly diagram of Fig. 1.
Embodiment
See also Fig. 1, sink of the present invention comprises a radiator 10, reaches a radiation fan 20 that is fixed on the described radiator 10.
Radiator 10 comprises a base 11, is provided with some radiating fin 12 at the upper surface of base 11.The lower surface of base 11 can contact with the heat dissipation element (as central processing unit (CPU)) for the treatment of on the computer main board, treats that the heat that heat dissipation element produces is sent on the radiating fin 12 via base 11.These radiating fin 12 give off obliquely from the base 11 of radiator 10, and are the form of drawing in gradually from top to bottom.The centre of these radiating fin 12 surrounds a space that is frustoconic shape, and its top is the intake grill of radiator 10.Be provided with two guide vanes 13 after being positioned at outer field each radiating fin 12,13 of two adjacent guide vanes that adjacent skin two radiating fin are 12 form an air guide hole 14, from the distinguished and admirable radiating fin of flowing through of described intake grill after flow out by described air guide hole 14.
See also Fig. 2, radiation fan 20 is rounded, and it comprises that two circular one first magnetic poles 21 and are installed in second magnetic pole 22 in first magnetic pole 21.Be equiped with some flabellums 23 in second magnetic pole 22, in better embodiment of the present invention, some flabellums 23 are shaped on second magnetic pole 22.These flabellums 23 extend to 24 places, axle center of radiation fan 20, and are centrosymmetric about this axle center 24.Described axle center 24 stretches out and forms a main shaft 25, and main shaft 25 links to each other with first magnetic pole 21 via some connection ribs 26.Be equiped with some coils 27 on described first magnetic pole 21, some coils 27 can be electrical connected in order to receive from a power source voltage with described computer main board.The height of described first magnetic pole 21 is greater than the height of second magnetic pole 22, and the magnetic of described first magnetic pole, 21 internal surfaces and second magnetic pole, 22 outer surfaces is opposite.
See also Fig. 3, radiation fan 20 is fixed on the intake grill place of described radiator 10.In better embodiment of the present invention, radiation fan 20 is fixed on the radiator 10 in the mode that screw fixes, and second magnetic pole 22 is the magnetic pole of plastic material.When having electric current to flow through in the coil 27, the magnetic field that first magnetic pole 21 and second magnetic pole are 22 produces an active force by 27 pairs first magnetic poles of coil 21,21 pairs second magnetic poles of first magnetic pole 22 produce a direction opposite reaction simultaneously, make second magnetic pole 22 rotate with respect to first magnetic pole 21.Second magnetic pole 22 rotates around axle center 24 and main shaft 25 under the effect of this reaction force, rotates thereby drive some flabellums 23.Therefore according to Ampere's law, the size of this reaction force is directly proportional with the number of turn of coil 27 and the size of current of flowing through coil 27, and the size of current of the number of turn by changing coil 27 or flowing through coil 27 can change the rotating speed of radiation fan 20.Because coil 27 and flabellum 23 are separated, the motor that is positioned at the flabellum middle part on the traditional heat-dissipating fan has been saved, and when some flabellum 23 high speed rotating, the surface of entire heat dissipation fan 20 all will produce distinguished and admirable, can improve radiating efficiency greatly.Second magnetic pole 22 is the lighter plastic material of weight, can further alleviate the weight of radiation fan 20, improves radiating efficiency.The number of turn of coil is subjected to the restriction of motor weight on the traditional heat-dissipating fan, and the number of turn of the coil of installing on first magnetic pole 21 among the present invention 27 no longer is restricted, and therefore can improve the rotating speed of fan greatly by the number of turn that increases coil 27, improves radiating efficiency.
The fan that sink of the present invention adopts flabellum 23 and coil 27 to be separated has saved the motor that is positioned at the flabellum middle part on the traditional heat-dissipating fan, and the border circular areas that makes entire heat dissipation fan 20 rotate all will produce distinguished and admirable, has improved the radiating efficiency of radiation fan 20.Radiation fan 20 is installed on the direct-firing fixing radiator 10 in better embodiment of the present invention, can improve the radiating efficiency of radiation fan 20 in radiator 10 middle parts greatly.But radiation fan 20 of the present invention is not limited to be applied to also can be applicable on other various types of radiators on the direct-firing fixing radiator.
