Embodiment
Figure l is the schematic diagram of the fan of the present invention from device forward observation, and Fig. 2 is the sectional view intercepted along the A-A line in Fig. 1, and Fig. 3 is the sectional view intercepted along the B-B line in Fig. 1.In as can be seen from Fig. 1 to Fig. 3, fan 100 comprises pedestal 1 and is positioned at the fan main body on pedestal 1, fan main body comprises fan frame 2, be positioned at the impeller 9 of fan frame 2, be positioned at the motor 10 for drives impeller 9 rotary work of fan frame 2, the fan housing 16 for air inlet that is connected with the rear end of fan frame 2 and the downstream that is positioned at impeller 9 and with the fan housing 15 for giving vent to anger fanned frame 2 and be connected.
Motor 10 is an alternating current motor, and this motor has the rotating shaft 7 of the X that parallels to the axis, and impeller 9 is an axial-flow blower, and motor 10 is fixed with motor casing 17, and motor casing 17 is fixed by screw and fan housing 16.
Fan housing 15 is identical with size with the structure of fan housing 16.Each of fan housing 15 and fan housing 16 comprises around axis X and 6 fluid directors 31 arranging of the gap being separated by certain and two plectanes 6 being connected with a fluid director near axis X, and these 6 fluid directors 31 all have the length D2 along axis X direction.
Can be clear that from Fig. 2, it is D6 that each fluid director 31 comprises the distance that the first conducting element 81 of annular and the second conducting element 82, first conducting element 81 of annular and the second conducting element 82 be separated by; Fluid director 31 comprises side, two ends 13,14, first 21 and the second side 20, first conducting element 81 comprises first side 42 with convex outward and second side 41, second conducting element 82 with inner sunken face comprises first side 44 with convex outward and second side 43 with inner sunken face.
As can be seen from Figure 2, the gap that 6 fluid directors 31 of fan housing 15 or fan housing 16 are separated by certain is arranged, and in any two adjacent fluid directors 31, the first side 21 of one of them fluid director is relative with the second side 20 of another fluid director; Any two adjacent fluid directors 31 be jointly defined for delivery air air-flow path 12, for inputting the suction port 8 with height D4 of air-flow and the air outlet 4 with height D3 for output gas flow.
It can also be seen that from Fig. 2, in any two adjacent fluid directors 31, there is first Q1 and second point Q2 respectively in first point of cross surface 47 of each cross surface 45 that the Plane intersects of the airflow direction P at the air outlet place that the fluid director that a fluid director wherein 31 is adjacent with these two with the short transverse D comprising the air outlet 4 that these two adjacent fluid directors limit limits is formed and second point of cross surface 48, the straightway 39 of connection first Q1 and second point Q2 is made to be D1 to the distance of the first conducting element 81 of another fluid director 31 wherein, simultaneously, there is thirdly Q3 and the 4th Q4 respectively in first point of cross surface 47 of each cross surface 45 that another fluid director 31 is wherein formed with described Plane intersects and second point of cross surface 48, making by the straight line 40 of thirdly Q3 and the 4th Q4 to the distance of the second conducting element 82 of one of them fluid director 31 is D5.
In the present embodiment, D1 is about 0, D2, and be 50mm, D3 to be 8mm, D4 be 9mm, D5 be about 0, D6 is about 12mm.With reference to figure 2 and in conjunction with the value of D1 and D5, easily find out, the fan of the present embodiment, its human eye be cannot see with various angle in the outside of fan housing 15 or fan housing 16 all at all and is positioned at impeller 9 inside fan housing 15 or fan housing 16 and other parts, its human body is also difficult to touch the parts such as impeller 9 by the air-flow path 12 of fan housing 15 or fan housing 16, namely fan of the present invention can hide the parts be positioned at inside fan housing 15 and fan housing 16 completely, the fan of this kind of structure is conducive to improving attractive in appearance and improving the Security used, and can effectively export the air-flow formed by impeller 9.
It can also be seen that from Fig. 2, fan housing 15 has multiple air-flow path 12 for transmitting air-flow, and the air-flow that impeller 9 is formed can be exported by these air-flow paths.Because these air-flow paths are along radially-arranged perpendicular to axis X, the Radial Flow of the air-flow that can effectively stop impeller 9 to be formed, thus the Radial Flow loss effectively reducing air-flow.
Can be clear that from Fig. 2, the distance that first conducting element 81 of fluid director 31 and the second conducting element 82 are separated by is D6, fan housing 15 or fan housing 16 can be divided into two large divisions like this and adopt mould manufacture respectively, and can the demoulding smoothly, thus be conducive to the batch production of product; In addition, this kind of fan housing is that the space of D6 does not arrange diversion component owing to there is its length, is conducive to reducing the quality of fan housing and manufacture cost and reduces the transmission loss of air-flow.
