BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator used in an air conditioner for a vehicle, and more particularly, to a radiator tank having a radiating core formed integrally with a heat radiating core through a double injection, and a radiator including the radiator tank.

Generally, in a vehicle equipped with an internal combustion engine, when heat generated during operation of the engine is conducted to a cylinder head, a piston, a valve, etc., and the temperature of these components excessively increases, the strength of the component decreases due to thermal expansion or deterioration, 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, and the engine oil is deformed to cause abnormal wear of the cylinder, and the piston is fused to the inner wall surface of the cylinder .

Therefore, in a vehicle equipped with an internal combustion engine, a water-cooled cooling device for cooling the engine by circulating cooling water is provided. The water-cooled cooling device circulates cooling water, which absorbs heat generated during engine operation, to a water pump, lowers the temperature of the cooling water, and then supplies cooling water to the engine to cool the engine A radiator as a heat exchanger, and a cooling fan and a water temperature controller for increasing the cooling efficiency of the cooling water by forcibly blowing the air to the radiator.

Hereinafter, a radiator tank and a radiator using the radiator tank according to the present invention will be described in detail with reference to the accompanying drawings.

2 to 4, the radiator 100 of the present invention includes a heat dissipation core 110 and a radiator tank 130 coupled to upper and lower portions of the heat dissipation core 110.

The heat dissipation core 110 has a plurality of heat dissipation tubes 111 having a fluid space therein so as to allow cooling water to flow therethrough. The heat dissipation cores 110 are provided with a heat dissipation fin 112 for heat dissipation through the heat dissipation tubes 111 .

The heat dissipation tube 111 and the heat dissipation fin 112 are preferably formed of a metal material having a high softening ratio so that the heat of the heated cooling water can be efficiently discharged. 110) can be applied.

A header 120 is installed on the upper and lower sides of the heat dissipation core 110, respectively.

The header 120 is for coupling a radiator tank 130 and a heat dissipation core 110 to each other. The header 120 is disposed above and below the heat dissipation core 110, And a skirt portion 122 extending upward or downward from the edge of the panel 121.

The header 120 is in the form of a box that opens upward and an opening of the tubes is formed on the bottom surface.

The radiator tank 130 includes a main body 131 injected with synthetic resin and a gasket 140 injected at the lower end of the main body 131.

The main body 131 has a predetermined inner space 132 opened at one side to be coupled with the heat dissipation core 110 and a passageway 133 through which the cooling water can flow into and out of the inner space 132 is formed . In the case of the main body 131 coupled to the upper side of the heat dissipating core 110, the heated cooling water flows into the main body 131 while cooling the heat of the engine through the passageway 133, The radiating cooling water is discharged through the passage 133. In this case,

The main body 131 has an edge of the opened end coupled to the panel 121 of the header 120 so that the cooling water that has passed through the cooling water or tube to be introduced into the tube together with the panel 121 can stay for a predetermined time Thereby forming a storage space.

In addition, a coupling groove 134 through which the gasket 140 can be doubly formed is formed at an opening side end of the main body 131.

The gasket 140 is formed at one open edge of the main body 131 through a double injection as described above and is formed of a material having an elastic force and tightly coupled to the panel 121 of the header 120.

The gasket 140 includes an insertion part 141 inserted into the coupling groove 134 and a sealing part 140 connected to the end of the insertion part 141 and positioned between the lower end of the body 131 and the panel 121 The cooling water is prevented from being formed between the header 120 and the radiator tank 130 because the sealing portion 142 is tightly coupled to the panel 121. [ .

Since the gasket 140 is formed in a state of being coupled to the main body 131 through the double injection, the possibility of leakage between the sealing part 142 and the main body 131 is low and the sealing part 142 and the panel 121 The possibility of leakage after joining of the radiator tank 130 and the heat dissipating core 110 is remarkably reduced.

When the gasket 140 is injected into the main body 131 that is primarily formed so as to form the through hole 135, the molten resin is injected into the coupling groove 134 and the through hole 135 The insertion portion 141 and the fastening portion 143 are formed. Since the gasket 140 of the present embodiment is fitted into the through hole 135 formed in the main body 131, the gasket 140 and the main body 131 are physically coupled, The engagement state of the gasket 140 can be stably maintained.

In addition, the header 120 is formed of a metal material capable of magnetically coupling, and the gasket 140 is formed of a synthetic resin containing a magnet by double injection.

The headers 120 contacting the gaskets 140 are formed of a metal material capable of being magnetically coupled and the magnets are included in the gaskets 140 so that assembling is easy when the radiator tanks 130 are coupled to the heat dissipating core 110, Thereby preventing the formation of a spacing space between the header 140 and the header 120, thereby preventing leakage of the cooling water.
