Abstract
The utility model relates to a coaxial double-wing different-direction ventilator. Both ends of a coaxial double-wing motor are respectively fixed with a transverse flow fan impeller and a centrifugal fan impeller, and are matched with an independent transverse flow fan volute and a centrifugal fan volute; the cross section of an air inlet of the transverse flow fan volute and the cross section of an air outlet of the centrifugal fan volute are at the same plane. The utility model can realize that at the duct interface point of the same face, air gets in from one side and is exhausted from the other side, and air directions are opposite. The utility model has the advantages of compact structure, and can be applied to a compact cross flow heat exchanger.
Description
The utility model is the incorgruous ventilator of a kind of coaxial double-vane, belongs to the aeration technology field.
Existing coaxial double-vane blower fan, generally be both wings entirely for centrifugation blade or complete be the crossing current fan blade, and the flow blower casing shape unanimity of both wings, like this on same interface plane, the air current flow direction by two impellers is the same.If coaxial double-vane centrifugal blower is used for a cross flow type heat exchanger, the part air channel need be done more reversing, make the air channel become complicated, volume is bigger than normal.Say on the principle, change the shape of flow blower casing and the blade outlet angle of crossing current fan blade, can make the two ends airflow direction of coaxial double-vane crossflow fan opposite.But when crossflow fan used as air blast, its blast was little, if the exhaust outlet front end is equipped with heat exchanger, its operational effect is obviously not as the air inducing pattern.
The purpose of this utility model is to provide a kind of coaxial double-vane incorgruous ventilator, and it can not only satisfy on same interface plane, and turnover wind is staggered to flow, and its air blast side and air inducing side have suitable blast.
For realizing such purpose, blower fan adopts coaxial double-vane motor, and a side of motor is fixed with cross-flow impeller, and is furnished with the crossing current spiral case; Opposite side is centrifugal blower fan blade wheel fixedly, and is furnished with anticentripetal spiral casing.Blower fan when normal operation, at same plane blower fan jointing, the outer air blast of centrifugal impeller side direction, the cross-flow impeller side then plays the induced draught fan effect.
The utility model not only can be used with heat pipe heat exchanger, stacked heat exchanger or finned heat exchanger etc., as the energy-saving type air conditioner air interchanger, also can use separately, as the air interchanger of compact type, enclosed space.
Fig. 1, Fig. 2 are an embodiment's of the present utility model structural representations.
As shown in Figure 1, an end of double-vane motor 1 connects crossflow fan impeller 2, and the other end connects centrifugal blower fan blade wheel 3, and crossflow fan impeller 2 is furnished with independently crossflow fan spiral case 4, and centrifugal blower fan blade wheel 3 is furnished with independently centrifugal blower volute 5.
As shown in Figure 2, the intake grill cross section 6 of crossflow fan spiral case is arranged at grade with the exhaust outlet cross section 7 of centrifugal blower volute.
Claims (3)
1, the incorgruous ventilator of a kind of coaxial double-vane has been fixed two draught fan impellers respectively at the two ends of coaxial double-vane motor, and the draught fan impeller that it is characterized in that being fixed on coaxial double-vane motor (1) two ends is respectively crossflow fan impeller (2) and centrifugal blower fan blade wheel (3).
2, the incorgruous ventilator of coaxial double-vane as claimed in claim 1 is characterized in that crossflow fan impeller (2) is furnished with independently crossflow fan spiral case (4), and centrifugal blower fan blade wheel (3) is furnished with independently centrifugal blower volute (5).
