Embodiment
Figure 1 shows that the three-dimensional exploded view of heat abstractor first embodiment of the present invention, this heat abstractor 100 comprises a radiator 10 and a radiator fan 20.Wherein, this radiator 10 and a heat-generating electronic elements (figure does not show) hot link, this radiator 10 is collapsible radiators, by single sheet metal (as aluminum metal film) through being bent to form continuously, it has some fin 12, these fin 12 keep at a certain distance away and arrange in row mutually, and this radiator fan 20 is used for this radiator 10 is carried out forced heat radiation.
This radiator fan 20 is a centrifugal radiator fan, comprises a housing 22, a stator (figure does not show) and a rotor 24, and this stator and this rotor 24 are installed in this housing 22, and this rotor 24 comprises some flabellum 24a.
This housing 22 comprises a loam cake 222, a bottom 224 and a sidewall 226.This loam cake 222 is provided with a fresh air inlet 222a, and this bottom 224 is provided with some fresh air inlet 224a.This sidewall 226 is one " U " type structure, and forms a semi-closed structure with rectangle air outlet 221 with this bottom 224 and loam cake 222.Wherein, the height of these air outlet 221 place's sidewalls 226 is higher than the height of other local sidewalls 226, so that accommodate this radiator 10.
Please refer to Fig. 2, this stator and this rotor 24 are installed in this housing 22 prejudicially, the outermost end of these flabellums 24a and this sidewall 226 keep at a certain distance away and form a runner 223, for improving the flow velocity of the cooling blast 30 that rotor 24 produces, along counterclockwise direction promptly on the flow direction of this cooling blast 30, this runner 223 broadens gradually.At these runner 223 the widest part, the flabellum 24a of this rotor 24 and this sidewall 226 form first-class road outlet 223a, with the relative opposite side of this runner exit 223a, this sidewall 226 is in being provided with a tongue mouth 223b triangular in shape near the position of air outlet 221 to rotor 24 projections.
Please refer to Fig. 1 and Fig. 2, this radiator 10 is arranged at corresponding to this rotor 24 in the air outlet 221 of this housing 22, and this radiator 10 is the two-part structure, and it has a fine and close section 12a and a loose section 12b.This densification section 12a is to being provided with by runner exit 223a, and this loose section 12b is to being provided with by tongue mouth 223b.This radiator 10 aligns with the outermost end of the air outlet 221 of this housing 22 away from an end of this radiator fan 20, the fin 12 of this densification section 12a is longer and stretch in this runner exit 223a than the fin 12 of loose section 12b, and the spacing among this loose section 12b between the fin 12 is greater than the spacing between the fin 12 among this densification section 12a.
Please refer to Fig. 3, this radiator 10 is arranged in the air outlet 221 of this housing 22, and the loam cake 222 of this housing 22 and bottom 224 be close to the upper and lower end face of this radiator 10, cooperates with these fin 12 to form runner and pass through for cooling blast 30.
By above narration as can be known, because this runner 223 broadens in the counterclockwise direction gradually, make when rotor 24 rotates, runner exit 223a place is that the cooling blast 30 of upstream has maximum flow velocity, correspondingly, the fin 12 of the fine and close section 12a of this radiator 10 has maximum length and minimum spacing, and the flow direction of the cooling blast 30 of upstream is substantially parallel with the fin 12 among the corresponding densification section 12a, improves the radiating efficiency of this densification section 12a effectively.In addition, extremely be somebody's turn to do a loose section 12b from this densification section 12a, the length of these fin 12 reduces and spacing increases, the cooling blast 30 that makes close this tongue mouth 223b promptly be positioned at low flow velocity zone, downstream is easier to flow through, the cooling blast 30 that remedies the downstream is owing to existing angle to cause the defective that flow velocity descends with fin 12, reduce the flow resistance of low flow velocity zone radiator 10 effectively, promptly by with the spacing size between the fin 12 to the setting that is inversely proportional to of intensity size that should cooling blast 30, make the spacing of fine and close section 12a of the bigger upstream airflow correspondence of intensity less, and the spacing of the less pairing loose section 12b of downstream airflow of intensity is bigger, reduce the flow resistance of these radiator 10 integral body, improve the radiating efficiency of this heat abstractor 100.
Please refer to Fig. 4, it is depicted as the three-dimensional exploded view of heat abstractor second embodiment of the present invention, the difference of itself and first embodiment is: this sidewall 227 is an arcuate structure, and itself and this loam cake 225 and bottom 229 are formed a semi-closed structure with arc air outlet 221b.This radiator 10a is a collapsible radiator, and it has some fin 11, and this radiator 10a is to should the curved arrangement of air outlet 221b.Same, this radiator 10a comprises a loose section 11b who is positioned at the fine and close section 11a of cooling blast 30 upstreams and is positioned at cooling blast 30 downstreams and is connected with this densification section 11a.The spacing of the loose section of gap ratio between the fin 11 of this densification section 11a 11b is little, and length is longer than loose section 11b, and the fin 11 of this densification section 11a stretches in this runner exit 223a.
Please refer to Fig. 5, this radiator 10a is circular-arc inner edge 13 near the end formation one of this rotor 24, this inner edge 13 keeps roughly the same distance with the end of the flabellum 24a of this rotor 24, this radiator 10a forms two orthogonal outsides 15,17 away from an end of this rotor 24, passes through a breach 19 transition between this two outside 15,17.This radiator 10a is to should runner exit 223a place being that the spacing of fin 11a of current rate maximum is less, to improve the radiating efficiency of this place's fin 11.The fin 11 that is positioned at the fine and close section 11a of cooling blast 30 upstreams is arranged in parallel, the flow direction with corresponding cooling blast 30, the fin 11 that is positioned at the loose section 11b in cooling blast 30 downstreams then is provided with the angle of inclination, to cater to the flow direction of this downstream part cooling blast 30, make the flow direction setting of the corresponding cooling blast 30 of direction of each fin 11 of this radiator 10a, so that reduce the angle between the flow direction of fin 11 and cooling blast 30 as much as possible, thereby reduce the flow resistance of this radiator 10a, improve the radiating efficiency of this radiator 10a.Setting by this two outside 15,17 and this breach 19, make this radiator 10a to should runner exit 223a and the fin 11 at tongue mouth 223b place longer, remainder is shorter, promptly this radiator 10a is longer to fin 11 that should the higher part of cooling blast 30 wind speed, and wind speed is shorter than the fin 11 of lower part, thereby effectively reduce the flow resistance of this radiator 10a, improve the radiating efficiency of this radiator 10a.
In addition, because radiator 10 and radiator 10a among above-mentioned two embodiment are collapsible radiators, and collapsible radiator is for the radiator that piles up buckle-type radiator or other kinds, can more easily regulate angulation between length, the spacing between the fin and the fin of fin, thereby make this radiator 10 and radiator 10a have the advantage that is easy to make.Simultaneously, this collapsible radiator 10 and 10a can control and change the spacing between the fin flexibly in the processing and manufacturing process, and can be according to the shape and the length of computer volume inside structure and Flow Field Distribution situation design fin, can provide additional space to use such as the setting of breach 19 among above-mentioned second embodiment for associated uses such as installations.
In sum, setting by length, spacing and angle among this radiator 10 and the radiator 10a, reduce the flow resistance of this radiator 10 effectively, improve the area of dissipation of this radiator 10, thereby effectively improve the radiating efficiency of this heat abstractor 100, make this heat abstractor 100 have advantage of higher cooling efficiency.
