Problems solved by technology

[0002] In some large places, such as convention and exhibition centers, large supermarkets, shopping malls, textile production workshops and other places, due to the high population density and relatively sealed environment, the temperature inside is relatively high in summer, so it is necessary to pass The air conditioner cools down, but the air conditioner consumes a lot of energy
[0003] Moreover, in the production process of some mechanical workshops, due to the operation of the machines inside the workshop, the temperature inside the workshop is always in a high state. Therefore, in order to provide a comfortable working environment for the staff in the workshop, it is generally installed in the workshop Ventilation equipment (cooling fan), which cools the workshop through the wind force of the cooling fan, but the cooling effect of the cooling fan is poor and the power consumption is high

Abstract

A novel exhaust fan comprises an air bellow, an air blower support arranged outside the air bellow, and a control cabinet. An air blower is arranged on the air blower support, and an air nozzle of the air blower is communicated with the interior of the air bellow. The air bellow is provided with an air outlet matched with the air nozzle of the air blower, the air outlet and the air nozzle of the air blower are located on the same horizontal line in the air bellow, and the air outlet is tangent to the outer contour of the air bellow. The air bellow is provided with a rotating shaft sleeved with a roller, fan blades are evenly distributed on the surface of the roller, the headwind sides of the fan blades are concave curved surfaces, and the downwind sides of the fan blades are circular arc surfaces. Supporting seats concaved inwards are arranged on the left side and the right side of the air bellow, and the rotating shaft penetrates through the side walls of the air bellow and extends to the supporting seats. Generators are connected to the two ends of the rotating shaft through flange plates. The novel exhaust fan is simple in structure, the utilization rate of air energy is high, the utilization rate of energy is increased, and the electricity consumption of the exhaust fan in the working process can be reduced by 70%.

Description

technical field [0001] The invention relates to an exhaust fan, in particular to an exhaust fan. Background technique [0002] In some large places, such as convention and exhibition centers, large supermarkets, shopping malls, textile production workshops and other places, due to the high population density and relatively sealed environment, the temperature inside is relatively high in summer, so it is necessary to pass The air conditioner cools down, but the energy consumption of the air conditioner is relatively large. [0003] Moreover, in the production process of some mechanical workshops, due to the operation of the machines inside the workshop, the temperature inside the workshop is always in a high state. Therefore, in order to provide a comfortable working environment for the staff in the workshop, it is generally installed in the workshop Ventilation equipment (cooling fan) cools the workshop through the wind force of the cooling fan, but the cooling effect of th...
