In the present embodiment, the suction side 13 of conducting element 31 is positioned at the jointing place of the rear end 202 of the second split flow part 312 and the rear end 302 of the 3rd split flow part 313, the end 14 that blows out of conducting element 31 overlaps with the front end 101 of the first split flow part 311, the first side 21 of conducting element 31 is complicated curved surfaces, the most surfaces of this first side 21 axis X dorsad, the second side 20 of conducting element 31 is also a complicated curved surface, and the most surfaces of this second side 20 is towards axis X.
From Fig. 8 to Figure 10, it can also be seen that, outlet housing 15 also comprises the multiple fixed blocks 5 that are arranged in inner passage 12, and the first split flow part 311 of the conducting element 31 that fixed block 5 is adjacent with two that limit inner passage 12 is integrated.In the present embodiment, outlet housing 15 is about 10mm with the distance of impeller 9.
As can be seen from Figure 9, any two adjacent conducting elements 31 define inner passage 12, have highly for the suction port 8 of D4 and to have be highly the air outlet 4 of D3; In any two adjacent conducting elements 31, it is relative that there is part side the first side 21 of one of them conducting element 31 with the second side 20 of another conducting element 31, on every intersection 38 that the second side 20 of a conducting element therein and the plane that comprises the short transverse D of air outlet 4 that this second side 20 limits and the airflow direction P at the place, air outlet that this second side 20 limits form, always have point 22 and point 23, the straightway 39 of tie point 22 and point 23 is D1 to the distance of the first side 21 of another conducting element wherein.
In the present embodiment, the curve that intersection 38 is polyline shaped, point 22 is near the point on the second side 20 that the is positioned at front end 301 of the 3rd split flow part 313, point 23 is near the point on the second side 20 that the is positioned at front end 101 of the first split flow part 311, D1 is about 0, D2 is about 70mm, and D3 is about 20mm, and D4 is about 20mm.
With reference to the value of D1, from Fig. 9, easily find out, the fan of the present embodiment, its human eye also cannot see in 4 fronts, air outlet of outlet housing 15 impeller 9 and other parts of being positioned at outlet housing upstream at all with various angles, its human body is also difficult to touch impeller 9 by outlet housing 15, can hide the parts that are positioned at outlet housing upstream completely, this is conducive to improve the outward appearance of fan and improves the Security that fan uses.
Figure 11 is the 6th embodiment of fan of the present utility model.In Figure 11, easily find out, the fan shown in Fig. 9 of the fan shown in Figure 11 and the 5th embodiment is similar, and just the structure of the conducting element of outlet housing is different.
The conducting element of the present embodiment is that the two ends that increased by the 4th split flow part 314, the four split flow parts 314 on the basis of the conducting element shown in Fig. 9 are connected with the front end 101 of the first split flow part 311 and the front end 201 of the second split flow part 312 respectively.The conducting element 31 of the present embodiment has internal cavities 36.This kind of structure is conducive to alleviate the quality of outlet housing 15.In the present embodiment, D1 is also about 0, and therefore the fan of the present embodiment also can be hidden the parts that are positioned at outlet housing upstream completely.
In fact, multiple split flow parts can as the case may be, carry out integrated manufacture to two split flow parts wherein, also can carry out integrated manufacture to the part of a split flow part and the part of another split flow part.
Here it should be noted that, the air intake cover that the outlet housing for fan of the present utility model also can be used as fan is used.
Although shown and described and thought at present preferred embodiment of the present utility model, apparent, those skilled in the art can carry out various changes and improvements, and for example, the curvature on the thickness of conducting element, length and conducting element surface can change; Again for example, the mode that can adopt various grafting that is connected of the first split flow part and the second split flow part, near the surface that conducting element can arrange other shape air outlet adjusts the outgassing direction of gas port, and the airintake direction of suction port is adjusted near the surface that conducting element can arrange other shape suction port.These changes or improvement, all belong to the scope of the present utility model that appended claims limits.
