Abstract
The utility model relates to a blowing type heat radiating fan with bidirectional air inlet, which comprises a base and an upper cover, wherein, a fan wheel is arranged in the base, one end of a soleplate of the base is preset with an air outlet, an air inlet is formed in the upper cover, and the upper cover is arranged on the base. In addition, a through hole is arranged on the soleplate of the base, and the through hole can be arranged on any position on the soleplate. Or a plurality of ribs are formed on the inner edge of the through hole matching with a stator, the end of the rib is formed with an inner chassis, the stator is arranged on the inner chassis, and a core shaft of the fan wheel is pivoted in the stator. When the fan wheel rotates, air can be led from the air inlet and the through hole at both sides and can be discharged from the air outlet. The utility model is provided with bidirectional air inlet structure at both sides, so air flow leading effect is better, and the utility model can effectively increase heat radiation efficiency.
Description
The utility model is a kind of blast-type cooling fan of two-way air intake, refers to a kind of blast-type cooling fan with two-way air intake of both sides especially.
General small heat-dissipating fan, comprise axial flow type heat elimination fan and centrifugal heat emission fan, axial flow type heat elimination fan is meant that the priming of air-flow is from top to bottom to blow, centrifugal heat emission fan then is based on blast-type cooling fan, referring to Fig. 3 and shown in Figure 4, this is present common blast-type cooling fan 4 structures, in base 40 tops loam cake 50 is set, base plate 41 peripheries of base 40 form wall 42, and at one end reserve air port 43, the base plate 41 of base 40 forms closing forms with wall 42, and in the accommodation space of base 40 impeller 60 is set, and housing 61 bottoms of impeller 60 are provided with axle and are hubbed at that (stator is a traditional structure in the stator, figure does not show), again, air inlet 51 is set in the loam cake 50, loam cake 50 is arranged on the base 40, and when activating impeller 60 rotations, outside air can be introduced by air inlet 51, and by the rotation of impeller 60 air-flow is sent, thereby electronic package is dispelled the heat.
The use of above-mentioned blast-type cooling fan 4, though can dispel the heat for the electronic package that heats up,, present electronic product is more done littler, and function is more and more many, make the arrangement of inner space use necessary comprehensive consideration, for example more make to heal frivolous mobile computer, its positioned inside space constantly is compressed, the function that adds electronic package heals high power consumption more greatly, the temperature that is produced is also more and more high, and therefore, it is not enough that the thermolysis of traditional blast-type cooling fan 4 more and more seems.
The purpose of this utility model is: a kind of " blast-type cooling fan of two-way air intake " is provided, and it has both sides two-way air intake effect, can make air-flow priming effect better, and can reach better radiating effect.
The technical solution of the utility model is to provide a kind of blast-type cooling fan of two-way air intake, blast-type cooling fan comprises base and loam cake, in the accommodation space of base impeller is set, the base plate periphery of base forms wall, and Yu Yiduan reserves the air port, form air inlet in the loam cake, loam cake is arranged on the base, the activation rotation of impeller, outside air is introduced via air inlet, and by impeller rotation and air-flow is sent by air outlet, wherein: through hole is set on the base plate of base, makes blast-type cooling fan form the two-way air intake structure.
The blast-type cooling fan of aforesaid two-way air intake, wherein: through hole inner edge set on the base plate can form several ribs, and rib tip forms interior chassis, on the interior chassis stator is set, and the axle of the housing bottom of impeller is hubbed in the stator.
The advantage of " blast-type cooling fan of two-way air intake " of the present utility model is, can form the air-flow priming of two-way air intake, thereby raising radiating efficiency, that is, in the base plate of general blast-type cooling fan, offer through hole, can make the air-flow priming in comparatively airtight and frivolous installing space more active, and can reach better radiating effect.
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is an assembled sectional view of the present utility model.
Fig. 3 is the schematic appearance of traditional blast-type cooling fan.
Fig. 4 is the assembled sectional view of traditional blast-type cooling fan.
At first, please cooperate referring to shown in Figure 1, it is the three-dimensional exploded view of the utility model blast-type cooling fan 1, it comprises base 10, loam cake 30, and impeller 20 is set in the accommodation space of base 10, wherein, base plate 11 peripheries of base 10 form wall 12, and Yu Yiduan reserves air port 13, formation air inlet 31 in the loam cake 30, and form wall 32 in periphery, loam cake 30 is arranged on the base 10, and when activating impeller 20 rotations, outside air can be introduced via air inlet 31, and air-flow is sent, and can carry out the thermolysis of air-flow priming by the rotation of impeller 20.
Design of the present utility model, in order to obtain the radiating effect of better air-flow priming, on the base plate 11 of base 10, through hole 14 is set, the purpose of through hole 14 is set, be to make blast-type cooling fan 1, comprise the through hole 14 that forms air inlet 31 and base plate 11 in the loam cake 30, form the two-way air intake structure, and through hole 14 positions in the utility model, on can being arranged at base plate 11 any one sentence, more can cooperate the installing of stator 17, and form several ribs 16 at through hole 14 inner edges, chassis 15 in rib 16 terminal the formation can be provided with stator 17 on the interior chassis 15, and the axle of housing 21 bottoms of impeller 20 can be hubbed in the stator 17.
Embodiment of the present utility model, can cooperate referring to shown in Figure 2, it can be the setting shape and be installed in the mobile computer, and when impeller 20 activates rotation, outside air can be introduced by the air inlet 31 of blast-type cooling fan 1 both sides and through hole 14, and by the rotation of impeller 20, and air-flow is outwards blowed by air outlet 13 places, form the priming effect than air flow of two-way air intake, thereby improve radiating efficiency.
