Description

The mounting structure of radiator for vehicle

The present invention relates to a structure for mounting a radiator for a vehicle, and more particularly, even if the mounting portion of the radiator is damaged due to a vehicle collision, the radiator for a vehicle can be fixed and reused by fixing the radiator to the vehicle without exchanging additional parts or radiators. It's about the structure.

In general, a carrier is disposed in front of a vehicle, and a radiator is fixed to the rear of the carrier. The radiator cools the coolant heated while circulating the engine to an appropriate temperature through heat exchange with external air, and is mounted on the carrier together with a cooling fan disposed at the rear.

In the process of being driven by 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 the radiator. In addition to such a case, vibration generated while the vehicle is traveling is transmitted to the radiator through the vehicle body. Noise is generated due to vibrations generated during driving of the cooling fan or driving of the vehicle, or wear is generated on parts that fix the radiator.

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

1 is a front view showing a radiator 1 according to the prior art. As shown in FIG. 1, the conventional radiator mounting part includes an upper support part 11 and a lower support part 12, a carrier 2 to which the lower rubber 14 is coupled to the lower support part 12, and the upper rubber ( 32) together with the bracket 30 coupled to the support 11, and a fastening pin 21 protruding at the upper and lower portions, and a lighter 1 having the fastening pin 21 inserted into the upper rubber 32. . According to the conventional radiator 1 configured as described above, the vibration of the vehicle or the vibration generated when the cooling fan is driven is absorbed by the mounting rubbers 13 and 14 to mitigate the vibration between the vehicle body and the radiator 1.

However, according to the configuration of the conventional radiator mounting unit described above, when the vehicle collides, the radiator 1 is pushed to the rear and the mounting unit is damaged. Due to the damage of the mounting part, the radiator 1 is required to replace the entire radiator 1 for repair or separate parts for fixing the radiator 1 to the carrier 2, so that an additional assembly process is performed and repairs due to this. The cost is also set high.

In addition, the Research Council for Automobile Repairs (RCAR), which calculates the standards for durability and stability of each vehicle element, evaluates the degree to which each vehicle standard is applied. It is a standard in the calculation. In other words, the higher the durability and stability of each element of a vehicle, the better it will be evaluated by the World Vehicle Repair Technology Research Committee, and thus the insurance premium of the vehicle can be lowered.
