摘要
本文重点介绍新型专利,自力式三叉形高效排气帽的设计原理,结构特性以及空气动力性能检测结果,和旧式风帽相比,此产品的突出优点,不但能保障在任何风向和风力的情况下,都不发生风雨倒灌现象,而且还利用了室外风力,形成排风主管的抽力(即产生负静压),变不利因素为有利因素。另外此产品的阻力较小,阻力系数仅为0.83。
Design principle, structural characteristics and test result of aerodynamic performance of self-actuated Y shaped high efficiency ventilation cap （ innovation patent） is mainly introduced in this paper. Compared with the old type ventilation cap, this product has many advantages. Not only can it guarantee that wind or rain will not flood into room despite of the wind force and wind direction. but forms draft （negative static pressure） of exhaust pipe by taking advantage of the outdoor wind force, so tunas disadvantageous factors into advantageous ones. Moreover, the resistance of the productis relatively low, and its coefficient is only 0.83.
