Technical Field [0001] The present invention relates to a radiator mounting structure for a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a radiator for a vehicle, and more particularly, to a radiator mounting structure for a vehicle which can mount a radiator on a vehicle without replacement of a radiator, Structure.

Generally, a carrier is disposed in front of the vehicle, and a radiator is fixed to the rear of the carrier. The radiator cools the heated cooling water while circulating the engine to an appropriate temperature through heat exchange with the outside air, and is installed in the carrier together with the cooling fan disposed at the rear side.

In the process of driving the cooling fan, vibration is generated by a rotating power or an electric motor, and the vibration is transmitted to a vehicle body that fixes the radiator through a radiator. In addition to this case, the vibration generated during traveling of the vehicle is transmitted to the radiator through the vehicle body. Noises are generated by vibrations generated during driving of the cooling fan or running of the vehicle, and wear is generated on the parts fixing the radiator.

In order to suppress the vibration generated in the radiator, conventionally, in the step of fixing the radiator to the carrier, a buffering rubber is provided between the radiator and the carrier, and the radiator is fixed to the buffering rubber by using a mounting device .

According to the conventional radiator 1 configured as described above, vibration of the vehicle or vibration generated when the cooling fan is driven is absorbed by the mounting rubber 13, 14, and vibration between the vehicle body and the radiator 1 is mitigated.

However, according to the configuration of the conventional radiator mounting portion, when the vehicle collides, the radiator 1 is pushed rearward and the mounting portion is broken. The radiator 1 needs to be replaced with another part for fixing the radiator 1 to the carrier 2 or replacing the entire radiator 1 for repairing the radiator 1 due to breakage of the mounting part, The cost is also set high.

The RCAR (Research Council for Automobile Repairs), which measures the durability and stability of each component of a vehicle, evaluates the corresponding degree of each vehicle. It is the standard for calculation. That is, the higher the durability and stability of each element of the vehicle, the better the evaluation from the World Vehicle Repair Technology Research Committee, thereby lowering the premium of the vehicle.

The upper and lower panels 240 and 430 and the left and right panels 440 and 450 are connected to each other so that the carrier 400 is formed into a substantially square frame shape with the central portion 460 being hollow.

The carrier 400 surrounds the radiator 100 in a rectangular frame shape. Outer air enters the empty central portion 460, passes through the radiator 100, and is heat-exchanged with the cooling water. Here, the carrier 400 is formed with a coupling hole 410 around the rectangular frame so that the radiator 100 can be mounted.

The radiator 100 cools hot cooling water, which absorbs heat generated by the engine, by heat exchange with the outside air. The fan 100 and the shroud assembly 100 for forcedly blowing air to the radiator 100 are installed at the rear of the radiator 100, Not shown) may be disposed. The radiator 100 is installed in front of the engine room and includes a header tank 110, a tube 120, a fin 130, and a fastening member 140.

The header tank 110 is formed by a combination of the header 113 and the tank 114, and is provided in a pair so as to be spaced apart from each other by a predetermined distance. At this time, the header 113 is in the form of a plate, and a tube insertion hole (not shown) into which the tube 120 is inserted is formed, forming a space through which the tank 114 and the cooling water flow. The header tank 110 is provided with an inlet pipe 111 and an outlet pipe 112 through which cooling water is introduced and discharged. 2 to 7, the mounting structure of the radiator 100 for a vehicle according to the present invention is not limited to this, and various design modifications are possible.

Both ends of the tube 120 are inserted and fixed to both sides of the pair of header tanks 110. At this time, a plurality of the tubes 120 are spaced apart from each other by a predetermined distance so as to form a flow path through which the cooling water flowing into the header tank 110 flows through the inlet pipe 111, and are arranged in parallel with the air blowing direction.

The pins 130 are interposed between the tubes 120. The fin 130 expands an area of heat dissipation with air flowing between the tubes 120 so that the cooling water flowing inside the tube 120 efficiently exchanges heat with the outside air.

The coupling member 140 has a hollow portion 141 formed in a plate shape extending from the tank 114 (see FIG. 3). 2 to 7, the radiator mounting structure for a vehicle according to the present invention is not limited to this, and various design changes are possible.
