What Causes the Noise in Car Fan Blades?
1 Answers
The causes of noise in car fan blades are as follows: 1. Deformation of the fan blades in the air conditioning system, it is recommended to replace the fan. 2. Damage to the motor of the fan in the air conditioning system, it is recommended to replace the fan. 3. Excessive impurities in the air conditioning system, it is recommended to clean the air conditioning system. More details are as follows: 1. The car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. The coolant flows inside the radiator core, while air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, and the cold air heats up by absorbing the heat from the coolant. 2. The materials and manufacturing technologies for car radiators have advanced rapidly. Aluminum radiators, with their significant advantages in material lightweighting, are gradually replacing copper radiators in the passenger car and light vehicle sectors. Meanwhile, copper radiator manufacturing technology and processes have made substantial progress, with copper brazed radiators showing clear advantages in engine radiators for buses, construction machinery, and heavy-duty trucks. 3. Overseas passenger cars are mostly equipped with aluminum radiators, primarily for environmental protection reasons (especially in Europe and the United States). In Europe, aluminum radiators account for an average of 64% of new passenger cars. 4. From the perspective of the development prospects of China's car radiator production, brazed aluminum radiators are gradually increasing. Brazed copper radiators are also being applied in buses, trucks, and other engineering equipment.
