Description

Technical Field

[0002] The car radiator is an indispensable and important component in the cooling system of the car water-cooled engine. The car radiator is mainly composed of the upper water chamber, the lower water chamber and the radiator core. The coolant flows in the radiator core, and the air passes outside the radiator core. The hot coolant cools down due to the heat dissipation to the air, and the cold air heats up due to the absorption of the heat emitted by the coolant, so the radiator is a heat exchanger. The function of the radiator is to dissipate heat and cool down, to ensure that the engine does not overheat during operation, so that the engine can work at the most suitable temperature. The radiator is not allowed to leak, otherwise it will cause the radiator's heat dissipation performance to decrease, the engine water temperature will be too high, and affect normal driving.

[0003] At present, because the testing environment is to test the sealing of the radiator in a stationary state, a slight leak may not be detected, but it may leak during driving. This problem makes it impossible to correctly determine the leaking location of the customer complaint product, and thus it is impossible to analyze the cause of the leak and improve the product quality.
