Field of the Invention
The present invention relates to an air duct and a cooling system for a vehicle. More particularly, the present invention relates to an air duct and a cooling system for a vehicle for improving cooling performance and aerodynamic performance.
Description of Related Art
Generally, an air duct is a passage through which air passes, and is a pipe for guiding air to parts requiring air from a part through which air can easily flow inside.
For example, there are an air duct that guides air to be sucked into an engine and an air duct for cooling a brake system.
Recently, techniques for preserving temperature of an engine and minimizing fuel consumption at the time of initial starting of the engine have been actively developed.
However, cooling of an engine may not be performed well, fuel consumption may be deteriorated during high speed driving, and heat damage may be generated to components which are disposed to a periphery of an exhaust passage at a high temperature if only the method for preserving temperature of an engine is performed. In addition, the performance of cooling an engine and fuel consumption may be deteriorated, and the heat damage may be become serious if air flowing through a radiator grille is interfered with by ancillary machinery disposed to the periphery of an engine.
