Description

Radiator {Radiator}

The present invention relates to a radiator. More particularly, the present invention relates to a radiator, and more particularly, to a radiator in which a first region for forming a cooling water flow path in the air flow direction and a second region for storing cooling water are formed by combining a header and a tank, And to a radiator which can increase the productivity by simplifying the structure for controlling the pressure and the cooling water.

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 cooling of the engine is incomplete, the lubricating function of the oil film on the inner circumferential surface of the cylinder is lowered. In addition, the engine oil is deteriorated to cause abnormal wear of the cylinder and fusion of the piston to the cylinder inner wall surface .

In order to cool the engine, a water-cooled cooling device is usually installed in the vehicle.

The water-cooled type cooling device lowers the temperature of 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.

Particularly, the radiator cools the cooling water whose temperature has risen while passing through the engine, and includes a first header tank 10 and a second header tank 20; A tube 50 having both ends fixed to the first header tank 10 and the second header tank 20 to form cooling water flow paths; And a pin (60) interposed between the tubes (50).

At this time, the first header tank and the second header tank include a header into which the end of the tube is inserted and a tank that surrounds the header.

However, the volume of the inside of the radiator changes due to a change in temperature due to the flow of the cooling water, so that the internal pressure is excessively increased. On the contrary, there is not enough cooling water to cool the engine.

Accordingly, the radiator communicates with the reservoir tank to discharge the cooling water in the radiator to the reservoir tank when the pressure inside the radiator rises excessively. When the temperature or pressure in the radiator falls, the cooling water is supplied into the radiator do.

A radiator cap for regulating the pressure inside the radiator is provided in the tank of the radiator and a pipe is connected to the reservoir tank in the cap so that it is difficult to secure a sufficient space in the engine room, The tank is formed as a separate member, and the miniaturization is hindered due to the configuration for connecting the tank, and the manufacturing process becomes difficult.

In order to solve the above-described problems, a radiator in which the reservoir tank 70 is integrated with the radiator tank 20 has been proposed, which is shown in FIGS. 1 and 2.

Since the remaining configuration of the radiator is the same as the conventional one, reference numerals refer to the above configuration.

The reservoir tank-integrated radiator tank is advantageous in that the reservoir tank, which is manufactured separately, is integrally formed with the radiator tank, thereby simplifying the structure.

In addition, the cooling water injecting unit provided above the reservoir tank can not be integrally injected with the basic injector of the reservoir tank integrated radiator tank, and a step of attaching (fusing) the cooling water injecting unit forming member after forming the basic injection molding is added .

In addition, the radiator shown in FIG. 1 requires a space inside the engine room by a region in which the reservoir tank is formed in the width direction, so that the design of the carrier or the like must be changed. When the radiator needs to be formed in a certain space, The length is shortened and the heat exchange performance may be deteriorated.
