Thin roof ventilator

Abstract

The invention discloses a thin roof ventilator which comprises a plurality of rows of parallel structured trusses. Outer guard plates are arranged around the structured trusses. The thin roof ventilator is characterized in that each row of structured trusses is provided with a plurality of ventilation units. Middle V-shaped rain baffles are connected between opposite ventilation units in each row. Partitions, upper v-shaped rain baffles and V-shaped catch channels are arranged between each two adjacent rows of ventilation units respectively. Windshield valve plates are hinged to each two adjacent rows of structured trusses. The thin roof ventilator has the advantages that the thin roof ventilator has natural load-carrying capacity, base materials can be saved greatly, manufacturing and installation ways of products are simplified, standardization and popularization are easy; the thin roof ventilator has the function of automatically adjusting wind shielding, external air can be prevented from flowing back, rain is prevented from leaking, unattended ventilation can be achieved; the thin roof ventilator has the function of replacing a roof, allows for large-area ventilation and lighting for buildings, is effective in ventilation and lighting and is highly functional in wind shielding regulation.

Description

technical field [0001] The invention relates to a building energy-saving ventilation device, in particular to a thin roof ventilator. Background technique [0002] The demand for building energy-saving applications has stimulated the development and application of building natural ventilation technology products. In recent years, thin roof ventilators have gradually been selected by certain designs and users. A kind of roof ultra-thin streamline ventilator disclosed by CN201589368U and a kind of assembled light roof ventilator etc. disclosed by CN202501595U. [0003] However, the development of conversion technology has gradually become erroneous, and the original simple and economical natural ventilation product technology tends to be complicated: 1. The board molded special-shaped material technology used is not conducive to product standardization, popularization and popularization, and is not conducive to product material selection It is interchangeable with applicat...

Problems solved by technology

According to the ventilation flow formula Q=μ F m3 / s, must For ventilation devices with specifications, the increase in overlap reduces the effective flow area F inside the ventilator, and the low (thin) shelter structure increases the ventilation resistance after increasing the exhaust air bypass flow, and the flow coefficient μ Reduced, these methods of strengthening wind shelter all reduce the ventilation flow Q, that is, the ventilation performance of the product decreases

[0005] In order to enhance the wind-shielding performance, CN202501595U discloses an assembled light roof ventilator with a translational valve plate device, but since the valve plate device is located at the air inlet at the bottom of the ventilator , when the valve plate is closed, the ventilator will lose its ventilation ability, and external pollutants are more likely to fall on the valve plate with the wind, and the falling snowflakes will melt and drip into the building, causing pollution in the building
