Cooling system for vehicle

Abstract

A cooling system for a vehicle that system includes a radiator disposed in a front of the vehicle, and introduced with cooling water thereinto to cool the cooling water through heat exchange with exterior air;. In addition, a first condenser is disposed at a first side of the radiator in a width direction of the vehicle and connected with the radiator via a cooling water pipe to be introduced with the cooling water, and introduced with refrigerant via a refrigerant pipe to condense the refrigerant through heat exchange with the cooling water therein. A second condenser is interconnected with the first condenser via the refrigerant pipe to be introduced with the refrigerant condensed by the first condenser, and disposed in a front of the radiator to additionally condense the refrigerant through mutual heat exchange of the exterior air introduced while driving the vehicle and the refrigerant.

Benefits of technology

[0019]According to a cooling system for a vehicle, exemplary embodiments of the present invention, condensing pressure may be reduced and condensing performance of refrigerant may be increased by applying both a water-cooled type using cooling water and an air-cooled type using outdoor air while condensing the refrigerant to improve cooling performance and the cooling system for a vehicle integrally configured to be included in a radiator cooling the cooling water through heat exchange with the exterior air to improve package performance.

[0020]As the condensing pressure of the refrigerant is reduced and t

Problems solved by technology

However, in the conventional air-conditioner system, when a water-cooled condenser is applied in cooling for condensing the refrigerant, cooling water exchanges heat with the refrigerant in the condenser and thus a refrigerant temperature at an outlet of the condenser rises, thereby increasing required power.

Further, the water-cooled condenser has a larger heat capacity of the cooling water than an air-cooled condenser and thus condensing pressure drops, but a difference in temperature between the cooling water and the refrigerant is substantially small and the temperature of the cooling water is higher than that of outdoor air, and as a result, it is difficult to form sub cool.

Therefore, whole cooling
