Abstract
Description
The present invention relates to a radiator for a vehicle, and more particularly, to a radiator for a vehicle, which further comprises a tube reinforcing portion which is inserted and fixed at one or both ends of the tube to a predetermined depth, And more particularly, to a vehicle radiator that can be assembled by a simple insertion process.
Generally, in a vehicle equipped with an internal combustion engine, heat generated during operation of the engine is conducted to a cylinder head, a piston, a valve, and the like. As a result, if the temperature of these components excessively increases, the strength of the component decreases due to thermal expansion or deterioration, The life of the engine is shortened and the combustion state is deteriorated, so that knocking or early ignition occurs and the output of the engine is also lowered.
In addition, when the engine is cooled insufficiently, the lubricating function of the oil film on the inner circumferential surface of the cylinder is also lowered, and the engine oil is deformed, thereby causing abnormal wear of the cylinder and fusion of the piston to the inner wall surface of the cylinder .
In order to cool the engine, a water-cooled cooling device is usually installed in the automobile.
The water-cooled type cooling device is to cool the cooling water circulating through the cylinder block and the cylinder head by the water pump, and includes a radiator, a cooling fan, and a water temperature controller for radiating the cooling water.

As a related patent, a radiator for a vehicle has been disclosed in Korean Patent Publication No. 2006-0067639 (published on June, 2006, entitled: Vehicle Radiator).
In the meantime, the radiator has a flow path through which high-temperature cooling water having passed through the engine flows through the inlet pipe, passes through a core portion formed of the radiating fin and the tube, and then discharged through the outlet pipe.
At this time, the core of the radiator is subjected to stress while repeatedly stretching and shrinking due to the high temperature and low temperature cooling water flowing therein, so that the durability is lowered due to the temperature load and the pressure load, In the bonded region, the problem of fracture due to the difference in the degree of thermal expansion occurred.
Particularly, a folded tube applied for thinning of a tube is more durable.
In order to solve this problem, durability of the conventional radiator is improved by adding a brazing process to the end of the tube by inserting the
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a tube reinforcing part, which is inserted and fixed at one or both ends of a tube, The present invention provides a vehicle radiator that can enhance the durability of the tube without interfering with the flow of the heat exchange medium in the tube and can be assembled by a simple insertion process.

The vehicle radiator according to the present invention further includes a tube reinforcing portion which is inserted and fixed at one or both ends of the tube to a predetermined depth and is formed by bending the wire in a predetermined form so that the durability of the tube can be improved without interfering with the flow of the heat exchange medium in the tube And can be assembled by a simple insertion process.
That is, unlike the conventional comb-type tube reinforcing part, which interferes with the flow of the heat exchange medium in the tube, and a complicated insertion process of a forced fit method is added, the wire having the same thickness as the tube inner width is bent Thus, the tube durability is improved without interfering with the flow of the cooling water, and a slight elastic deformation is possible. Thus, the assembly process can be simplified because the tube can be easily inserted and fixed in the tube without applying a large pressure for forced fitting.
In addition, according to the present invention, since the tube reinforcing portion is inserted into the header coupling portion of the tube to reinforce the strength, a crack occurs in the header coupling portion of the tube due to the stress due to the temperature deviation that a partial area of the last tube adjacent to the outlet pipe receives. Can be prevented.
