Title:
EXHAUST DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/179084
Kind Code:
A1
Abstract:
Provided is an exhaust device, comprising a ventilation pipe, a protective cover, and a support body. A fairing is arranged between the ventilation pipe and the protective cover; the fairing is a truncated-cone shell; the ventilation pipe is a pipe body with two ends being ventilated; the outer edge dimension of an upper port of the ventilation pipe is smaller than the outer edge dimension of a lower port of the fairing; an upper port of the fairing is connected to the lower portion of the protective cover; the upper port of the ventilation pipe is inserted into the lower port of the fairing; the ventilation pipe and the fairing are connected to each other by means of the support body; and a space formed by the ventilation pipe, the fairing and the protective cover forms an exhaust passage. The fairing and the ventilation pipe have flow guiding and rectifying effects on incoming flows and a suction effect on indoor gases. The device can use natural wind power and indoor hot air buoyancy for exhaust, has no backflow, no rotating parts and no additional wind direction tracking device, and has a simple structure, a low cost, long service life, no noise, and high exhaust efficiency. The device is applied to the sites where exhaust or ventilation and heat dissipation are required for structures.
