US 12,215,891 B2 · Wind pressure-driven air intake device

Abstract

This application discloses a wind pressure-driven air intake device for natural ventilation of zero power consumption. Such a device comprises multiple tunnels being arranged around a common central chamber, each having an inflow valve at its inner end connecting the central chamber and an outer end open to ambient airflow. The inflow valve allows only inward flow from a corresponding tunnel into the central chamber. The central chamber has an opening allowing airflow exit to a space to be ventilated. The device is capable of capturing ambient wind flow and wind pressure to be fed to the vented space regardless of wind flow direction towards the device, with no need for a powered air driver.
