Why does the car air conditioning cooling fan keep running at high speed?
1 Answers
When the temperature is too high, it operates at high speed, and when the temperature is normal, it operates at low speed for cooling, which is a normal phenomenon. Below is relevant information: 1. Classification: According to the direction of coolant flow in the radiator, radiators can be divided into two types: longitudinal flow and cross flow. According to the structural form of the radiator core, radiators can be divided into tube-fin radiator cores, tube-band radiator cores, and plate-type radiator cores. 2. Material: There are mainly two types of car radiators: aluminum and copper. The former is used for general passenger cars, while the latter is used for large commercial vehicles. The materials and manufacturing technology of car radiators have developed rapidly. While aluminum radiators have gradually replaced copper radiators in the field of cars and light vehicles due to their obvious advantages in material lightweighting, the manufacturing technology and process of copper radiators have made significant progress. Copper brazed radiators have obvious advantages in engine radiators for buses, construction machinery, heavy trucks, etc.
