Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
With a parallel fan power type air quantity variable end device for air conducting plate structure, its structure as shown in Figure 1.Comprise casing 1, the front end of casing is provided with First air air inlet 2 and secondary returning air port 3, and box back is provided with air outlet 4, and air inlet is provided with an air duct 5, is provided with Secondary Air blower fan 6, division board 7 and air baffle 8 in casing.
One time air duct 5 is vertically set on the diapire of casing, and arranges near left side wall, and the air outlet of an air duct is corresponding with air outlet.
Secondary Air blower fan 6 is obliquely installed, and Secondary Air blower fan overturning angle at 45 ° is arranged in the present embodiment.Secondary Air blower fan is arranged in casing right half side, and Secondary Air blower fan and an air duct are arranged relative to casing diapire and roof zero lap.In the utility model, the setting angle of Secondary Air blower fan can also be arbitrarily angled between 30 ° ~ 60 °, to guarantee the complete air-out direction suiting First air and Secondary Air.
Air outlet 4 is arranged on the roof of casing, and the outlet size that air outlet is positioned at First air side should be able to ensure to look from casing air outlet direction to device interior, can see First air air outlet completely, and without any partial occlusion; The outlet size that air outlet is positioned at Secondary Air side should be not less than the outlet size of Secondary Air blower fan, ensures to look to device interior from Way out, can see Secondary Air air outlet completely, as shown in Figure 2.
Division board 7 is arranged in the casing between Secondary Air air inlet and an air duct, send/return air chamber for what isolate First air and Secondary Air blower fan.In the utility model, division board is plate-like structure, the side of division board is arranged on the cabinet wall once between air duct and secondary returning air port, the opposite side of division board is arranged on the cabinet wall of air outlet one end of Secondary Air blower fan side, and consistent with air outlet direction; On the top board that other side seals of division board are connected to casing and base plate.
Air baffle 8 is arranged in the casing between First air outlet and Secondary Air outlet, for isolating First air air-out and Secondary Air air-out, and carrying out guide functions to Secondary Air, playing certain inducing action to First air.Air baffle planform, in the feature of " straight after frontal arc ", is nature circular shape near Secondary Air fan outlet position, near casing location of air supply inlet then in exporting parallel flat shape with First air.Namely air baffle comprises the arc section of transition connection and vertical section, as shown in Figure 1, the outer end of arc section is arranged on division board and installs the flat face section of Secondary Air blower fan near the side of an air duct, the outer end of vertical section is arranged on the centre position of casing air outlet, on the top board that other side seals of arc section and vertical section are connected to casing and base plate.Air outlet is divided into First air air-supply by vertical section and Secondary Air is blown two parts.
In the utility model, housing interior volume is divided into three individual cavity by division board, casing end and air baffle.Adopt this kind of structure can when Secondary Air blower fan is opened, Secondary Air will be send casing together with parastate with First air, thus avoid Secondary Air produces too high static pressure phenomenon generation in the gathering of First air air-valve downstream, and, because Secondary Air has higher wind speed relative to First air, thus certain inducing action can be had to First air, reduce First air downstream resistance, reduce Secondary Air fan operation resistance, reduce system cloud gray model energy consumption and noise.
In the utility model, the outlet side of Secondary Air blower fan is also provided with gravity-type check-valves 9, and during for ensureing that Secondary Air blower fan does not run, First air can not leak from this position.Gravity-type check-valves adopts other light materials such as light aluminum alloy materials or flame-retarded plastic to make, and can not bring too much running resistance to Secondary Air fan operation.
During utility model works, Secondary Air blower fan is opened, and under the effect of Secondary Air blower pressure, pushes gravity-type check-valves open, Secondary Air air-flow, under the effect of air baffle, smoothly becomes the airflow direction parallel with First air and send the air outlet of casing together with First air.
