Abstract
The utility model relates to the field of ventilation equipment, in particular to a double cross-flow fan. The double cross-flow fan comprises a volute with a first air cavity and a second air cavity on the left and the right respectively, a first baffle arranged at the front end of the first air cavity, and a second baffle arranged at the front end of the second air cavity. A first air inlet is formed by the first baffle and the left side of the volute, and a second air inlet is formed by the second baffle and the right side of the volute. A first air outlet is formed in the right side of the first baffle and the front end of the volute, and a second air outlet is formed in the left side of the second baffle and the front end of the volute. The first air outlet and the second air outlet are adjacent so that air can flow in a more centralized mode, and the air out-flowing directions are the same. Due to the fact that the air inlets are almost perpendicular to the air outlets, the distance in the vertical direction is shortened, the size of the fan is reduced, and the production cost is lowered.
Description
Technical field
The utility model relates to the ventilation equipment field, is specifically related to a kind of pair of cross flow fan.
Background technique
In ventilation field, the application of cross flow fan is very extensive, two cross flow fans refer to a kind of two wind wheels that have, the cross flow fan in two air channels, two cross flow fan General Requirements air quantity are large, volume is little, and nowadays the air intake passage of most of two cross flow fans and air-out passage be in the same horizontal line on market, thus, in the situation that keep air quantity certain, volume also can significantly increase, and on market, most of two cross flow fans are generally two Duct designs two independent spiral cases are arranged, the two cross flow fan costs that design like this are higher.
The model utility content
The purpose of this utility model is to overcome above-described shortcoming, and two cross flow fans that a kind of air quantity is large, volume is little, cost is low are provided.
For achieving the above object, concrete scheme of the present utility model is as follows: two cross flow fans comprise that left and right is respectively equipped with the spiral case in the first wind chamber and the second wind chamber, the second baffle of being located at the first baffle plate of the first wind chamber front end and being located at the second wind chamber front end; Be provided with the first wind wheel in described the first wind chamber, in described the second wind chamber, be provided with the second wind wheel; The left side of described the first baffle plate and spiral case forms the first intake grill, and the right side of described second baffle and spiral case forms the second intake grill; The front end of described the first baffle plate right side and spiral case forms the first exhaust outlet, and the left side of described second baffle and the front end of spiral case form the second exhaust outlet.
Wherein, the transverse section of described spiral case is " people " character form structure.
Wherein, the first baffle plate is provided with the first snail tongue near an end of the first exhaust outlet, and second baffle is provided with the second snail tongue near an end of the second exhaust outlet.
Wherein, the spacing between the first snail tongue and the second snail tongue increases to direction gradually along air-out.
Wherein, the described pair of cross flow fan also includes and the first wind wheel and the second wind wheel corresponding motor be connected with and the pedestal that is fixed in motor respectively.
The beneficial effects of the utility model are: the first exhaust outlet is adjacent with the second exhaust outlet, make Air Flow more concentrated, be that air-out direction is consistent, due to intake grill and the setting of exhaust outlet near normal, thereby saved the distance of vertical direction, and then reduced the volume of blower fan, reduced cost of production.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model being described in further detail, is not that practical range of the present utility model is confined to this.
As shown in Figure 1 to Figure 3, described pair of cross flow fan of the present embodiment, comprise that left and right is respectively equipped with the spiral case 2 in the first wind chamber 25 and the second wind chamber 26, is located at the first baffle plate 4 of the first wind chamber 25 front ends and the second baffle 5 of being located at the second wind chamber 26 front ends; Be provided with the first wind wheel 31 in described the first wind chamber 25, in described the second wind chamber 26, be provided with the second wind wheel 32; Described the first baffle plate 4 forms the first intake grill 21 with the left side of spiral case 2, and described second baffle 5 forms the second intake grill 22 with the right side of spiral case 2; The front end of described the first baffle plate 4 right sides and spiral case 2 forms the first exhaust outlet 23, and the front end of the left side of described second baffle 5 and spiral case 2 forms the second exhaust outlet 24.
As described in Figure 2, the first intake grill 21 is approximated to vertical setting with the first exhaust outlet 23, during work, the first wind wheel 31 and the second wind wheel 32 rotate and make air from first intake grill 21 in left side and second intake grill 22 inspirations respectively on right side, and the rotation of the first wind wheel 31 and the second wind wheel 32 continues to drive air and sends from the first exhaust outlet 23 and the second exhaust outlet 24; In the present embodiment, the first exhaust outlet 23 is adjacent with the second exhaust outlet 24, makes Air Flow more concentrated, be that air-out direction is consistent, due to intake grill and the setting of exhaust outlet near normal, thus the distance of having saved vertical direction, and then reduced the volume of blower fan, reduced cost of production.
Further, the structure that the transverse section of described spiral case 2 is " people " font; Therefore two groups of tubular wine wheels can share a spiral case 2, make the utility model compact structure, and cost is low, easy for installation.
Further, described the first baffle plate 4 is provided with the first snail tongue 41 near an end of the first exhaust outlet 23, second baffle 5 is provided with the second snail tongue 51 near an end of the second exhaust outlet 24, and further, the spacing between the first snail tongue 41 and the second snail tongue 51 increases to direction gradually along air outlet; The snail tongue has the wind-guiding effect, the air-flow that will blow out from exhaust outlet is rectified to the special angle scope, the flow direction that is air-flow is required air-out direction, the the first snail tongue 41 and the second snail tongue 51 that arrange, make the utility model not need to set out in addition wind pipeline and change air-out direction, greatly reduce the volume of blower fan, also reduced the loss of blast simultaneously.
Further, described the first baffle plate 4, second baffle 5 and spiral case 2 adopt the foam material to make, and therefore have certain noise reduction, in addition, make weight of the present utility model lighten, and because foam material cost is low, and then have reduced cost of the present utility model.
Further, the described pair of cross flow fan also includes and the first wind wheel 31 and the second wind wheel 32 corresponding motor be connected with and the pedestal 1 that is fixed in motor respectively; Each motor is coupling with corresponding wind wheel, and motor is fixed in pedestal 1, and the installation that pedestal 1 can facilitate the first baffle plate 4, second baffle 5 and spiral case 2 is set.
The above is only a preferred embodiment of the present utility model, and the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and is included in the protection domain of the utility model patent application.
