Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the utility model embodiment and accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.It should be noted that, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
Refer to Fig. 1, the utility model discloses a kind of CPU heat abstractor, comprise radiator 1 and radiator fan;
Radiator 1 is in the form of annular discs, and the surface of radiator 1 is circumferentially laid with radiating fin 4; The periphery of radiator 1 is uniformly distributed along the circumference to be provided with and is no less than three installation portions 6, is provided with circular blade 10 groove 5 between installation portion 6 and radiating fin 4;
Radiator fan comprises fan guard 2 and rotary fan 3; Fan guard 2 center is provided with stator unit 7, and stator unit 7 is provided with electric plates and stator winding, is electrically connected between stator winding with electric plates, and electric plates is connected with by wire and supplies plug 11 for what power; The periphery of fan guard 2 is laid with the installation unit 8 matched with installation portion 6, and radiator fan is installed on radiator 1 by the installation unit 8 of fan guard 2, is connected between installation unit 8 with stator unit 7 by dowel; The center of rotary fan 3 is provided with the rotor unit 9 of hat, the permanent magnet of annular is provided with in rotor unit 9, the center of rotor unit 9 is provided with rotating shaft, rotor unit 9 is covered on the bottom of stator unit 7, permanent magnet is positioned at the periphery of stator winding, and rotary fan 3 is rotatably connected with stator unit 7 by rotating shaft; The outside of rotor unit 9 is uniformly distributed along the circumference and is provided with blade 10, and the middle part of every sheet blade 10 is provided with groove, and the radiating fin 4 of radiator 1 is positioned at the groove of blade 10, and the end of blade 10 is positioned at blade 10 groove 5 of radiator 1.
The utility model and the maximum difference of prior art are: the utility model have employed the design of centrifugal suction airstream, but not merely blow toward radiator 1 and form radiating airflow.Adopt common blower fan to be right against radiator 1 in prior art to dry, air-flow in the head-on collision of radiator 1 surface, then can change direction.This air-flow is not owing to being self-assembling formation, and direction efficiency in the process changed of air-flow has been lowered, and this air-flow can not ensure the surface evenly circulating in every sheet radiating fin 4, thus reduces radiating efficiency.
During utility model works, be that blade 10 by being positioned at radiating fin 4 periphery produces air-flow, when rotary fan 3 rotates, blade 10 can detach outwards centrifugal for the air-flow of radiating fin 4 periphery, cause the air pressure of radiating fin 4 region to decline, form suction airstream.The air-flow at radiator 1 center constantly equably outwardly, is taken away the heat of radiating fin 4, is completed high efficiency and heat radiation.Air-flow is self-assembling formation, and midway does not change direction, and efficiency is not lost.And Principle of Rotating between rotary fan 3 and fan guard 2 and common DC brushless motor are as good as, are control stator winding by electric plates to produce alternating magnetic field, under being the interaction of permanent magnet, drive rotary fan 3 to rotate.
As preferably, the sheet body of described blade 10 is curved, and the bearing of trend of sheet body arc is contrary with the sense of rotation of rotary fan 3.When rotary fan 3 rotates, the blade 10 of arc can be stirred air and radially flow, thus formed suction airstream, principle and centrifugal pump similar.
Connected mode between installation portion 6 and installation unit 8 can be diversified.As preferably, described installation portion 6 is provided with threaded hole, and described installation unit 8 is provided with the through hole mated with threaded hole, is installed be connected between installation portion 6 with installation unit 8 by bolt.This connected mode is comparatively common, installs firmly, reliable and stable.
As preferably, described installation portion 6 is provided with back-off groove, and described installation unit 8 is provided with back-off tooth, and installation unit 8 is located in the back-off groove of installation portion 6 by back-off tooth button.This connected mode more for convenience, can complete without any need for instrument, and demolition and maintenance are also more convenient.
As preferably, the radiating fin 4 of described radiator 1 increases toward circumferencial direction area gradually from the center of circle.Also the time is needed because heat transmits on radiating fin 4, thus heat can be absorbed fast close to the side material area in the center of circle is less, and radiating fin 4 material area radially increases gradually, heat can be induced to accelerate radially to transmit, form the radial heat radiation to circumference from the center of circle.Then heat scatters and disappears in the air of periphery along with air-flow fast.
A kind of CPU heat abstractor provided by the utility model, what radiator fan adopted is the design of centrifugal suction airstream, forms natural circulation airflow, significantly improves radiating efficiency.Radiating fin 4 area of radiator 1 increases gradually along with radiating airflow direction, strengthens radiating effect further.And structure is simple, easily installs, can be applicable to various CPU, for the normal work of CPU provides stable environment.
The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
