Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to an automobile radiator with an integrated silencing cavity. Background Art

[0002] The car radiator is a key component in the cooling system of the car's water-cooled engine. It is responsible for maintaining the engine within a suitable operating temperature range to ensure engine efficiency and extend its service life. The basic structure of the radiator includes the water inlet chamber, the water outlet chamber and the radiator core. The radiator core is the most core part, usually composed of many small pipes and fins. In terms of working principle, the radiator operates through circulating coolant (usually a mixture of water and antifreeze). The hot coolant flows out of the engine, enters the water inlet chamber of the radiator, and flows through the densely arranged pipes in the radiator core. When the coolant flows inside the pipe, the cold air outside the radiator flows and flows through the gaps between the fins. This process realizes heat exchange: the coolant releases heat to the air, and the air is heated. After the heat is dissipated, the coolant becomes colder and returns to the engine through the water outlet chamber. The cycle repeats, continuously taking away the excess heat generated by the engine.

[0003] In order to speed up the heat dissipation effect, a cooling fan will be added to the radiator. However, the higher the operating speed of the cooling fan, the greater the wind noise generated. Especially under high-load working conditions, in order to meet more efficient heat dissipation needs, the fan has to run at a higher speed, which directly aggravates the noise problem.
