Abstract
A dual-flow ventilator is composed of vane wheel, casing, flow collector and supporting frame. The said vane wheel and casing are composed of centrifugal fan unit and axial-flow fan unit. The vane wheel is installed in casting. The supporting frame is linked to flow collector fixed to air inlet of casing. The centrifugal fans at both ends can generate higher air pressure.
Description
What the present invention relates to is a kind of dual-flow ventilator, and particularly a kind of dual-flow ventilator that is applicable to the split-type air conditioner indoor set group belongs to field of fluid machinery.
In prior art, the indoor units of separate type air conditioner all utilizes cross flow fan that cold (heat) air-flow is sent basically.Because the blast that cross flow fan produces mainly is dynamic pressure, performance characteristics is very soft, therefore when system resistance rises when wet cooling condition (for example), and air quantity can reduce a lot, makes refrigerating capacity decline, influences refrigeration.And the centrifugal multiblade blower fan also is a kind of blower fan of using often in the field of air conditioning, although can obtain elevated pressures, performance characteristics is better than cross flow fan, the width of impeller can not arbitrarily strengthen, and the ratio that generally is controlled at width and impeller diameter is less than 1.Therefore its outlet can not be made thin-and-long, and the increase of air quantity also is restricted.
The patent No. is CN 99113678.0, and name is called the patent of invention of " two-way blower fan ", and it mainly is " will have now receded disk impeller change by forward blade and backward vane be staggered and constitute "; " spiral case is the coaxial two-direction spiral case ".This blower fan belongs to a kind of of centrifugal blower, just to the both direction air-supply, is not suitable for the air-supply of the indoor units of air conditioner.
Deficiency and the defective of the present invention in order to overcome prior art improved the refrigeration of indoor units when wet cooling condition of air conditioner; Or make blower fan when system resistance changes greatly, and reduce influence to air quantity, design a kind of simple in structurely, can overcome ventilating machinary---the dual-flow ventilator of change in resistance greatly during work.
Content of the present invention: the present invention utilizes the quite similar characteristics of impeller of the impeller and the centrifugal multiblade blower fan of cross flow fan, constructs a brand-new blower fan---dual-flow ventilator.The structural type of centrifugal multiblade blower fan is adopted at its two ends, and the cross flow fan structure is then adopted in the centre.Therefore the intake grill of dual-flow ventilator is distributed in two ends and centre; Exhaust outlet is then merged by outlet centrifugal and the through-flow part.So dual-flow ventilator had both overcome the softer shortcoming of cross flow fan characteristic, remedied the centrifugal multiblade blower fan again and can not arbitrarily strengthen the deficiency that air quantity is restricted because of width.
The present invention mainly comprises impeller, shell, slip ring and support etc.Impeller and shell all are made up of centrifugal blower structure division and cross flow fan structure division.Impeller is made up of centrifugal partial blade, through-flow partial blade, import dish, centrifugal dividing plate, through-flow dividing plate and axle.The quantity of centrifugal and through-flow partial blade, turnover bicker can be designed to consistent, also can be different; Import dish and through-flow dividing plate are circular discs, and centrifugal dividing plate then is discoid disc, and the quantity of through-flow dividing plate can increase and decrease according to the impeller axial length.The two ends of the shell of dual-flow ventilator are the spiral cases of centrifugal blower, and intermediate section is consistent with the shell of cross flow fan.Its intake grill is made up of the intake grill of two ends centrifugal blower and the intake grill of through-flow part; Exhaust outlet is made up of the exhaust outlet of two ends centrifugal blower and the exhaust outlet of through-flow part.During assembling, at first impeller is packed in the shell, then support is welded on the slip ring, slip ring is screwed the intake grill place of shell again, the axle with the impeller two ends is fixed on the support at last.The drive motor of blower fan can pass through belt transmission, also can select disc type or outer rotor motor driven for use.When dual-flow ventilator was worked, the centrifugal blower at two ends part can produce higher blast, the resistance that rises when overcoming work.
The present invention has substantive distinguishing features and remarkable economic efficiency.
Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described:
Fig. 1 is the dual-flow ventilator structure principle chart
Fig. 2 is dual-flow ventilator blade wheel structure figure
Fig. 3 is that the dual-flow ventilator shell reaches into and out of the air port schematic representation
As Fig. 1, Fig. 2, shown in Figure 3, dual-flow ventilator mainly comprises impeller 1, shell 2, slip ring 3 and support 4.Impeller 1 and shell 2 are formed by centrifugal blower structure division and cross flow fan structure division.
The two ends of shell 2 are spiral cases of centrifugal blower structure, and intermediate section is consistent with the shell of cross flow fan structure.Have air inlet through hollow shaft mouth 11,12 on the both ends of the surface of shell 2, radially have an exhaust outlet 14,15 at the two ends of shell 2 spiral case; And the centre of shell 2 (through-flow part) bottom has intake grill 13, radially has exhaust outlet 16, and exhaust outlet 14,15,16 has constituted the exhaust outlet of dual-flow ventilator again jointly.
