Description

[0001] RADIATOR FOR VEHICLE [0002]

The present invention relates to an automotive radiator, and more particularly, to a radiator for an automobile which comprises an engine, an electric motor and an electric component of an internal combustion engine, and a cooling water supply unit for cooling the respective cooling water supplied to the intercooler through heat exchange with the outside air during running The present invention also relates to a radiator for a vehicle that reduces condensation and reduces airflow resistance by incorporating a condenser to improve the heat radiation performance and the overall cooling performance of the vehicle.

Generally, the automobile is operated by injecting a mixture of fuel and air into the engine cylinder and delivering the explosive force by the compression of the piston to the driving wheels. As described above, the engine which obtains the output by the explosion, The radiator has a cooling device such as a water jacket, and the function of cooling the cooling water circulating the water jacket is performed by the radiator.

The radiator having such a function is classified into a cross-flow type and a down-flow type radiator according to the configuration type, which is an air-cooled type which is cooled by outside air.

The cross flow and the down flow radiator which are classified according to the above configuration type are determined according to the flow direction of the cooling water. In the radiator according to the related art, the inlet and outlet tanks for the inflow and outflow of cooling water are arranged apart from each other, And cooling the cooling water flowing through the heat exchange with the outside air.

Here, the cross-flow type radiator is a system in which the inlet and outlet tanks are disposed on the left and right sides and the tubes are mounted so as to be stacked in the lateral direction so that the cooling water is cooled while circulating in the lateral direction.

In the downflow type radiator, the inlet and outlet tanks are arranged up and down, and the tubes connecting the respective tanks are stacked in the longitudinal direction so that the cooling water is circulated in the vertical direction.

The radiator thus configured is disposed forwardly inside the engine room of the ordinary vehicle so that the cool outside air flowing during traveling and the cooling water are heat-exchanged.

In recent years, an intercooler has been applied in which the compressed air is cooled by a turbine of a turbocharger applied to improve the output of the engine and supplied to the engine.

These intercoolers are classified into air-cooled type or water-cooled type, and the application of the water-cooled type is more expanded than the air-cooling type in order to improve the cooling performance and improve the fuel efficiency by improving the turbo rack.

In the case of a water cooled intercooler, cooled coolant is introduced through a radiator for an intercooler that is separate from the radiator that supplies cooling water to the engine, thereby cooling the compressed air.

However, since the conventional vehicle radiator is constituted by the radiator for the engine and the radiator for the intercooler and is applied in front of or behind the vehicle in front of the vehicle, the package is increased and the installation space is limited in the narrow engine room There is a problem.

In addition, as the space between the back beam and the engine room is reduced, the collision performance is lowered. Since the tubes of the respective radiators are different from the radiating fin heights, when the outside air flowing in the front of the vehicle passes through each radiator, There is a problem that the radiating performance of the radiator is deteriorated.

Further, when the radiating performance of the radiator is lowered, the cooling water can not be cooled to the required temperature, the overall cooling efficiency is lowered, and cooling water that has not been properly cooled is supplied to the engine and the intercooler, Thereby deteriorating the overall cooling performance of the vehicle.
