Description

Combined structure of tank and header for radiator in vehicle}

The present invention relates to a coupling structure of a tank and a header for an automobile radiator, and more particularly, to prevent over-compression of a gasket interposed between these phases when the tank and the header are combined, thereby contributing to the quality stability of the entire radiator.

The radiator is one of automotive heat exchangers, and the heat exchanger is a representative example of a condenser used in an air conditioning system, a radiator used for evaporator and engine cooling.

The condenser and evaporator of the heat exchanger heat the latent heat of the refrigerant in the high temperature or high pressure state or low pressure low temperature to liquefy the refrigerant or generate cold air by evaporation, and in the case of a radiator via the cylinder of the engine It cools the cooled water and exchanges it with the latent heat of surroundings to convert it into a low temperature state.

The radiator 10 of the heat exchanger as described above is shown in FIG. 1 and looks at it;

The radiator 10 is supplied with coolant to be heat exchanged and is coupled to the tank 11 for circulating the heat exchanged coolant and the header 12 coupled to the front of the tank, and having multiple flow paths between the header 12. It is composed of a center (15) coupled between the tube (13) and the tube (13) phase to improve heat exchange.

On the tank 11 of the radiator 10, a bracket 16 for mounting the radiator 10 in a firm state on the engine room is coupled.

The bracket 16 is brazed with the tank 11, the header 12, the tube 13 and the center 14, and means for confidentiality when the tank 11 and the header 12 are joined. Thus, the gasket 17 is interposed.

Conventionally, as shown in FIG. 4;

After the gasket 3 is interposed in the coupling groove 2 formed at both sides of the header 1, the coupling protrusion 5 of the tank 4 is forcibly coupled to the header 1 and the tank 4. .

When the header 1 and the tank 4 are combined as described above, since the depth to be combined is unknown, a case where the header 1 is inserted into an excessive depth or an insufficient depth may occur.

Insufficient airtightness may cause leakage of the coolant, and if it is inserted in an excessive depth, the coolant may leak due to damage to the gasket, header, and tank. There were problems such as poor quality safety.

Therefore, the present invention is designed to solve the problems as described above to improve the coupling protrusion of the tank so that the header and the tank can be combined to the most suitable depth to contribute to the improvement of quality and workability due to the stable coupling state For the purpose.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is a perspective view of a radiator for explaining the present invention, Figure 2 is a cross-sectional view of the combined state of the tank and the header of the radiator to which the technique of the present invention is applied, Figure 3 is a cross-sectional view taken from the portion A of FIG.

The radiator 10 is supplied with coolant to be heat exchanged and is coupled to the tank 11 for circulating the heat exchanged coolant and the header 12 coupled to the front of the tank, and having multiple flow paths between the header 12. It is composed of a center (15) coupled between the tube (13) and the tube (13) phase to improve heat exchange.

The tank 11 is provided with a bracket 16 for mounting the radiator 10 in the engine room, the gasket 17 is interposed in the coupling groove 18 of the header 12 as a means for maintaining airtightness. .

In the present invention, when the header 12 and the tank 11 are combined, the gasket 17 may be prevented from being damaged due to excessive coupling or insufficient coupling, and lack of adhesion.

To this end, in the present invention, the stopper 21 integrally determines a depth at which the coupling protrusion 20 can be inserted into the coupling groove 18 of the header 12 outside the coupling protrusion 20 of the tank 11. It is further formed and configured.

The stopper 21 preferably protrudes more than the outer end 22 of the coupling groove 18 of the header 12 when the stopper 21 is engaged.

According to the present invention configured as described above, the coupling protrusion 20 of the tank 11 is inserted into the coupling groove 18 of the header 12 when the tank 911 and the header 12 are coupled to each other. The stopper 21 further formed on the outside is engaged with the most suitable state because the stopper 21 is caught by the outer end 22 of the header 12 and no further insertion is made.

The present invention as described above has the effect of improving the quality and workability due to the stable coupling state by improving the coupling protrusion portion of the tank to be coupled to the most suitable depth when the header and tank coupling.
