| Abstract: | This article introduces mainly a new patent on the design principle, construction characteristics andexamination results of areodynamics of high efficiency tri-forked self-force exhaust hood. Compared with old fashionedexhaust hood, the outstanding advantage of this product is not only to be able to secure for wind or rain not to pour indown vent pipes under any wind directions or any wind force, but also to make use of outdoor wind to form extracting force(i.e. static pressure) of the main vent pipe. In addition, less resistance coefficient of the product is 0.83. |
