Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to a reinforced card-type radiator tube root reinforcement structure. Background Art

[0002] The radiator is a key component of the automobile engine cooling system. The performance of the radiator directly affects the power, economy and reliability of the automobile. The manufacturing processes of radiators are mostly the same. In the face of bad road conditions, the overall twisting of the body frame transmits the torque to the radiator water chamber through the left and right side panels of the radiator, and the water chamber is finally transmitted to the heat pipe through the main plate. This causes the heat pipe to bear a large force. At the same time, because the material of the heat pipe is thin, it cannot withstand the force transmitted from each component, which leads to damage to the heat pipe and affects the normal use of the radiator.

[0003] The damaged part of the radiator is mainly the tearing of the root position where the heat dissipation pipe is connected to the main plate, which shortens the service life of the radiator. After many experimental data, we found that the force on the outside of the tube root is greater than the force on the inside of the tube root, so the tearing damage mostly occurs on the outside of the root tube, but the tube root reinforcement structure in the prior art lacks protection for this part, which will cause considerable losses to the majority of car owners. For this reason, we improve and reinforce the radiator according to the specific use of the radiator in the vehicle. Utility Model Content
