Radiator of Automobile

Abstract

Disclosed is a radiator which can simplify the structure, cut down weight and costs, and reduce assembly process by coupling a plurality of core portions to a single header and a single tank portion. Furthermore, by arranging the plurality of core portions in a front-rear direction, the structure is simplified and it becomes easier to secure an installation space, thus allowing the radiator according to the present invention to be applied to more cars. Furthermore, by configuring the tank portion so as to be partitioned by a pocket or the like, heat transfer between the cooling water cooling the internal combustion engine and the cooling water cooling the electric field system is blocked, thereby improving cooling efficiency much more.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2008-0082461 on Aug. 22, 2008, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a radiator of an automobile, and more particularly, to a cooling system which efficiently cools an internal combustion engine and an electric side in a hybrid vehicle driven by an electric motor using a battery and an internal combustion engine using fuel such as gasoline.[0004]2. Description of Related Art[0005]A hybrid vehicle is a vehicle which obtains a driving force by combining an engine and a motor and simultaneously or selectively driving them.[0006]Here, electric parts including a driving motor generate heat when activated, and there is a need to install a cooling device for suppressing a temperature rise of the parts in order to keep input / outp...

AI Technical Summary

Benefits of technology

[0030]The radiator according to various aspects of the present invention can simplify the structure, cut down weight and costs, and reduce assembly process by coupling a plurality of core portions to a single header and a single tank portion.

[0031]Furthermore, by arranging the plurality of core portions in a front-rear direction, the structure is simplified and it becomes easier to secure an installation space, thus allowing the radiator according to the present invention to be applied to more cars.

[0032]Furthermore, by configuring the tank portion so as to be partitioned by a pocket or the like, heat transfer between the cooling water cooling the internal combustion engine and the cooling water cooling the electric field system is blocked, thereby improving cooling efficiency much more.

Problems solved by technology

However, the aforementioned conventional technologies have a problem that heat transfer may occur from a radiator for an engine with a high temperature to a radiator for an electric field loading apparatus because the radiator of the electric field loading apparatus and the engine radiator are integrally formed.

Owing to this, the cooling effect of the electric field loading apparatus is deteriorated, and hence the output and efficiency of the electric field loading apparatus is deteriorated due to a temperature rise of the electric field loading apparatus.

Additionally, the conventional technologies have a problem that in the case of vehicles coming with large engine displacement and vehicle weight, such as large-sized SUV and RV vehicles, it is difficult to set a high-capacity heat exchanger due to vehicle package constraints, thus making it difficult to use an integrated-type heat exchanger having a top-bottom structure (top part for an internal combustion engine and bottom part for an electric field) or a left-right structure (left side for an internal combustion engine and right side for an electric field).
