WIPO Patent Application WO/2016/153091
Kind Code:
A1
Abstract:
The present invention relates to an air flow control device and, more specifically, to an air flow control device that can enhance the cooling efficiency of construction equipment to prevent an overheating/overcooling-induced failure in various components, including a main control valve (MCV), which are installed inside the construction equipment, thereby extending the lifetime of the construction equipment. To this end, the present invention provides the air flow control device that comprises: a plate disposed between a cooling fan installed on the frame of construction equipment and the inside of the construction equipment to face the cooling fan; a connecting part that is formed on an edge of one surface of the plate that faces the cooling fan, and connects the plate to the frame of the construction equipment; and a door that is formed on the surface of the plate so as to be opened and closed and adjusts the flow of air that is generated in a cooling process through a cooling system of the construction equipment and is introduced into the construction equipment after the cooling process is completed.
