The heat dissipation fan is used in different industries as auxiliary equipment, mainly to do heat dissipation and cooling work, to ensure that the equipment is not burned by the heat generated by itself under long-term work. Once the cooling fan fails, it will affect the service life of the equipment. What are the reasons for the failure of the radiator fan? Below, Innocent technician explains for you:

1. There are some defects in the design of heat dissipation fan. If the parts are not properly matched, vibration or noise will occur when the fan is running. In addition, if the fan design structure is unreasonable and the material used is not good, it is easy to cause the cracks or breaks of the fan blades, resulting in failure.

2. The technological parameters of heat dissipation fans deviate from the design values, which often make the machine maintain over-speed and over-load operation in operation, or low-speed and low-load operation, which can not achieve the performance of fans and is prone to failure.

3. Faults in installation of heat dissipation fans, misalignment of spare parts or bad alignment of bearings will result in excessive fan load and easy burnout. If the fan rotor is placed unproperly, it is not detected according to the regulations, causing the fan to deviate and malfunction.

4. The aging of heat dissipation fans will cause fatigue of some parts of fans after long-term operation, local damage of rotors, surface pitting and local wear of parts affected by impact force, and faults of fan operation.

What are the reasons for the failure of the radiator fan? Here we are today. The main reason for the failure of heat dissipation fan is that the quality of heat dissipation fan itself is not good and the use effect is not good. Therefore, it is suggested that when buying heat dissipation fan, we should choose a strong fan manufacturer with good reputation to ensure the quality.
