Problems solved by technology

[0004] However, since the temperature of the cooling water rises rapidly due to high-temperature exhaust gas, there is a limit to stably controlling the cooling water temperature only by the existing cooling system in some severe driving modes
[0005] Cooling capacity can be increased when the hardware specifications of the radiator module and fan motor are improved, but there is a problem that the capacity of these components may not be infinitely increased due to the complex engine room layout and increased cost and weight
[0008] However, as the area of ​​the opening increases, the aerodynamic coefficient (Cd) value becomes higher and the driving resistance becomes larger, so the area of ​​the opening cannot be increased infinitely

Abstract

The application relates to an active air flap and a control method thereof. The active air flap includes: a first air flap disposed between a ventilation opening of a bumper and a radiator, and openably disposed in a first section facing the radiator; a second air flap disposed between the ventilation opening of the bumper and the radiator, and openably disposed in a second section bordering the first section facing the radiator; and an air guide member configured to guide air introduced into the radiator toward the first air flap and the second air flap.

Description

technical field [0001] The present invention relates to an active damper and a control method thereof, in which operation of the damper is selectively controlled by sections according to driving conditions of a vehicle while increasing the flow rate of air introduced into a radiator module, thereby contributing to improvement in cooling performance and fuel economy sex. Background technique [0002] Recently, with the strengthening of environmental regulations for exhaust gas, various technologies for improving exhaust gas purification capabilities have been developed. [0003] Generally, in order to improve the exhaust gas purification capability, it is necessary to optimize the catalyst to an activation temperature, and to cool the temperature of the exhaust gas by using cooling water to adjust the catalyst to the activation temperature. [0004] However, since the temperature of the cooling water rises rapidly due to high-temperature exhaust gas, there is a limit to stab...
