Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Please refer to Fig. 1 to Fig. 5, the invention provides a kind of multiple duct spiral case blower fan, comprising: housing 1, housing 1 is provided with intake grill 2 and multiple exhaust outlet 3, multiple exhaust outlet 3 is arranged along the circumference of intake grill 2; Fan blade 4, fan blade 4 is arranged in housing 1, and the intake opening of fan blade 4 and intake grill 2 are arranged accordingly.Preferably, the number of exhaust outlet 3 is four.
The present invention is provided with multiple exhaust outlet 3 on the housing of multiple duct spiral case blower fan, thus, can utilize the feature that spiral case blade system efficiency is high, noise is low, realize four sides air-out, thus be applied to multiple heating and ventilating equipment, realize quick heat exchange, have the advantages that structure is simple, cost is low.Especially, the present invention also can be applied in ducting system, improves air channel shunting inequality and increases air quantity simultaneously.
Preferably, housing 1 comprises the first housing 5 and the second housing 6, first housing 5 is removably connected with the second housing 6.First housing 5 and the second housing 6 are designed to the detachable structure in split type left and right, have the advantages that to be convenient to process, especially, the first housing 5 and the second housing 6 are by injection molded.
Preferably, the first housing 5 is removably connected by buckle structure 7 with the second housing 6.By buckle structure 7, can by the first housing 5 and the second housing 6 spacing be assembled into one, have dismounting simple feature.
Preferably, the number of buckle structure 7 is multiple, and multiple buckle structure 7 is uniformly distributed along the circumference of intake grill 2.Like this, the first housing 5 and the second housing 6 surrounding can be made to fasten tightr.
Preferably, in the embodiment shown in fig. 4, intake grill 2 is only arranged on the first housing 5.Like this, in this embodiment, due to the second housing 6 not arranging intake grill, therefore wind only can from the intake grill air intake of the first housing 5, then by the even air-out of each exhaust outlet.
Preferably, in the embodiment shown in fig. 5, the first housing 5 and the second housing 6 are provided with intake grill 2 respectively accordingly.Like this, in this embodiment, wind can from the intake grill air intake of the first housing 5 and the second housing 6, i.e. left and right air intake simultaneously, then by the even air-out of each exhaust outlet.
Preferably, the edge that the second housing 6 is corresponding with the first housing 5 is provided with the stiffened edge of L shape.Like this, the intensity at exhaust outlet place can be increased, prevent the plastics of housing partially soft and be out of shape, can also prevent from leaking out simultaneously.
Please refer to Fig. 6, present invention also offers a kind of ducting system, comprise main wind passage 8, multiple shunting air channel 9 and above-mentioned multiple duct spiral case blower fan 10, multiple duct spiral case blower fan 10 is arranged in main wind passage 8, and multiple exhaust outlets 3 of multiple duct spiral case blower fan 10 are arranged correspondingly with multiple shunting air channel 9 respectively.
As shown in Figure 6, wind is shunted after main wind passage 8, and air channel of the prior art can be inconsistent due to the pressure in each air channel, causes shunting inequality and air quantity to reduce.The present invention has installed multiple duct spiral case blower fan and has shunted in main wind passage, thus makes each shunting air channel 9 uniform distribution, improves the air quantity of system simultaneously, solves air channel shunting inequality and the long problem causing wind loss in air channel in project installation.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
