Stereo air-curtain wind curtain machine

Abstract

The invention discloses a three-dimensional air curtain air curtain machine. Specifically, the air curtain machine includes: an air inlet device through which external air enters the air curtain machine; The air collected by the wind device enters the aerodynamic fan; and the rectification structure of the air outlet, the high-pressure and high-speed airflow output by the aerodynamic fan is output to the air curtain machine through the air outlet rectification structure, forming a three-dimensional air curtain; the air outlet rectification structure includes strip air outlets The rectification structure and the rectification structure of the matrix point air outlet, the rectification structure of the strip air outlet adopts the structure of wing rectifier and comb rectifier to comb the air flow, and the rectification structure of the matrix point air outlet adopts the split rectifier structure. The air curtain machine of the present invention can form a three-dimensional high-pressure circulating air chamber, which can effectively isolate the convection of cold and hot air with a large temperature difference. The efficiency is as high as 89%, which is more energy-saving and efficient.

Description

technical field [0001] The invention relates to the fields of energy saving technology and environmental protection technology, and more specifically relates to a three-dimensional air curtain air curtain machine. Background technique [0002] Such as figure 1 As shown, the currently used and produced air curtain machines are all flat air curtain air curtain machines, and its technical form is to use a cross-flow fan to generate aerodynamic force, and a flat air curtain is generated at a straight air outlet. To isolate the convection of hot and cold air. Due to the limitation of the structure of this technical form, the plane air curtain produced is thin, scattered and weak, and the use effect is poor, and it cannot be applied to the cold storage with a large temperature difference (-18°C inside, 35°C outside, and cold storage). In the case of heat convection velocity 2.9m / s). In addition, when people and objects or forklifts pass through, the flat air curtain will be blo...

Problems solved by technology

Due to the limitation of the structure of this technical form, the plane air curtain produced is thin, loose and weak, and the use effect is poor, and it cannot be applied to the cold storage with a large temperature difference (-18°C inside, 35°C outside, and cold storage). In the case of heat convection velocity 2.9m / s)

Moreover, when people and objects or forklifts pass through, the planar air curtain will be damaged by the passing object and cause loopholes. In the case of frequent use of the channel, it will not be able to isolate the hot and cold air. Therefore, the planar air curtain has a large temperature difference. Or the effect is poor in frequent use
