Patent ID: 8091516

Claim:
A cooling device adapted to be disposed in an engine bay of a motor vehicle, comprising: a radiator; a radiator louver with at least one lamella for controlling a passage of a gas flow through said radiator; at least one bypass duct disposed to bypass said radiator and a closing element disposed to selectively close off said at least one bypass duct; and said closing element being operatively connected to said radiator louver such that an opening of said radiator louver effects a closing of said bypass duct by closing said closing element, and a closing of said radiator louver effects an opening of said bypass duct by opening said closing element; and said radiator louver and said closing element being coupled to one another such that a substantially uniform lift force, or a substantially uniform pitching moment, is imparted to the motor vehicle, regardless of a position of said at least one lamella of said radiator louver and a position of said closing element.
