Introduction of internal structure principle of roof ventilator without power



The non-powered fan is a device that USES the natural wind speed to drive the turbine rotation of the fan and the principle of indoor and outdoor air convection, accelerates and transforms the air flow in any parallel direction into the vertical air flow from the bottom to the top, so as to improve the ventilation effect of indoor ventilation. The fan does not use electricity, no manic sound, can run for a long time. Its basis air natural rule and airstream flow principle, reasonable setting is in the top of roofing, can discharge quickly indoor hot gas and foul gas, improve indoor environment.



Internal structure of unpowered roof ventilator



Introduction to the principle of internal structure composition of roof ventilator without power:



(1) excellent material.



The stainless steel ventilator of our company is made of 304, with 0.6mm pipe diameter and waterproof bottom plate thickness and 0.31 blade thickness. Color steel ventilator material used for the domestic famous color plate factory masteel products.



(2) 32 leaves.



According to the us authorities test 32 pieces of the design to meet the best aerodynamic design.



(3) angular change design.



The Angle changing pipe diameter of the ventilator in our company can be adjusted. This unique Angle changing design can make the ventilator meet the installation of roof with different slope.



Structure of 500 and 600 roof automatic ventilator



(1) waterproof bottom plate:



The size of waterproof bottom plate of type 500 ventilator is 750mm*750mm, while that of type 600 ventilator is 900mm*900mm. The thickness is 0.6mm stainless steel and 0.8mm color steel plate.



(2) angular diameter:



The diameter and height of the angular pipe diameter of type 500 ventilator are 50cm and 20cm respectively. The type 600 ventilator has a diameter of 60cm and a height of 25cm, and the classification of type 500 and type 600 ventilator is based on this. The angular diameter and thickness of stainless steel ventilator are 0.6mm and 0.8mm respectively.



(3) turbine head:



The turbine head is mainly composed of 32 blades. The width of the 500 type ventilator blades is 6.5cm, and the width of the 600 type ventilator blades is 8.31cm.



(4) bracket:



Both type 500 and type 600 ventilators have two brackets, the upper bracket is aluminum bracket and the lower bracket is nylon bracket. The thickness of the aluminum bracket is 4mm, which has strong anti-corrosion function, high strength and flexibility, and a person standing on the bracket steps constantly.



(5) central axis:



The power system of the ventilator, consisting of two bearings, an iron column and a rotary cylinder, is a closed structure, which enables the ventilator to be used for many years without maintenance.







Installation example of unpowered ventilator



1. Working principle of non-powered fan turbine fan is to use the thermal convection of air caused by natural wind force and indoor and outdoor temperature difference to promote turbine rotation so as to exhaust indoor hot air with centrifugal force and negative pressure effect.



2. Special energy efficiency brought by special design



1, curved wind blade is the best result after scientific calculation, can strictly ensure that the working state never let rain intrusion. High exhaust efficiency, as long as the breeze at least 0.2 meters or indoor and outdoor temperature difference more than 0.5℃, can be light and effective operation.



2. The center shaft is equipped with fine steps, so that the wind blades of the turbine will never be deformed under high-speed operation, thus greatly improving the service life of the fan.



3, variable Angle neck tube design, can make the fan in 0-22.5 degrees slope under the arbitrary installation, installation project is very simple, the average person can be installed within about 30 minutes.



3. Zero-cost operation cost, objective energy efficiency, economical installation cost and low maintenance cost. Four, no power fan USES:



1, the generation of air convection, exhaust heat.



2. Reduce air-conditioning load and increase indoor fresh air.



3, draw out the roof moisture, mold, steam, keep the roof dry. 4. Replace the heavy electric exhaust fan, reduce the cost of supports, save the electricity cost and reduce the noise.
