Vehicle window ventilation system

摘要

A vehicle window ventilation system of this invention contains vertical slots in forward portions of the window or frame. Air due to vehicle movement passes in the slots to the cavity between the windowpanes. There is a passage for airflow from the cavity rearward to the door handle where there is spacing for outward passage of air. The forward location of the vertical slots allows for the flow of air across a wide area of the windows and hence a minimum reduction of visibility due to moisture in the cavity. The air passageway rearward through the cavity between the windows and then through the door to the rearward located door handle allows for a dispersion pattern of air that covers a large amount of the surface area of the double pane window. While an external fan could be used to enhance the removal of flow of air the forward location of the vertical slots and the rearward location of the inner door passageway to the door handle alleviates the necessity of having a fan. The vertical slots allow the direction of airflow over the windowpanes inner surfaces from the top to the bottom of the panes.
