Abstract
The utility model discloses a cooling tower draught fan wing-shaped vane. The cooling tower draught fan wing-shaped vane comprises glass reinforced plastic layers, a macromolecule resin layer, a foam interlayer and support pillars. The cooling tower draught fan wing-shaped vane is characterized in that the foam interlayer is fixed between the glass reinforced plastic layers at two sides in a sticky mode through the macromolecule resin layer, and the two glass reinforced plastic layers are connected through a plurality of support pillars which penetrate through the foam interlayer. According to the cooling tower draught fan wing-shaped vane, a wing-shaped structural design is adopted, aeromechanics requirement is met, the efficiency of a draught fan is high, and noise is low. The foam interlayer is installed between the glass reinforced plastic layers at the two sides, and therefore the weight of the vane is reduced. Due to the connection between the support pillars and the glass reinforced plastic layers, overall strength of the vane is not affected, and cost is lowered.
Description
Technical field:
The utility model relates to a kind of used for cooling tower fan blade, relates in particular to a kind of blower fan of cooling tower airfoil blade.
Background technique:
The blower fan airfoil blade is the energy-efficient low noise blade that uses the aviation aerodynamic principle to design in recent years, can extensively send out to be used in blower fan and wind-driven generator series.The fan blade of used for cooling tower is bigger, need do the use down of wet two states, therefore, the structure and the material of fan blade is all had strict demand.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of blower fan of cooling tower airfoil blade is provided, and adopts the airfoil project organization, and forms with Composite Preparation, has light weight, power is big, durable advantage.
The technological solution of the utility model is following:
A kind of blower fan of cooling tower airfoil blade; Comprise frp layer, polymer resin layer, foam layer and pillar; It is characterized in that: foam layer is bonded and fixed at by polymer resin layer between the frp layer on two sides, and two frp layers are connected by a plurality of pillars that see through foam layer.
The beneficial effect of the utility model is:
1, adopt the wing-shaped structure design, meet the airmechanics requirement, fan efficiency is high, and noise is low.
2, be provided with foam layer in the middle of the frp layer of two sides, alleviated the weight of blade,, can not influence the bulk strength of blade again, reduced cost simultaneously owing to the connection between pillar and the frp layer.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1; A kind of blower fan of cooling tower airfoil blade; Comprise frp layer 1, polymer resin layer 2, foam layer 3 and pillar 4; Foam layer 3 is bonded and fixed at by polymer resin layer 2 between the frp layer 1 on two sides, and two frp layers 1 are connected by a plurality of pillars 4 that see through foam layer 3.
