[0002] The condenser fan assembly is an important component in the automotive air conditioning system. Its main function is to help the condenser dissipate heat. The function of the condenser fan assembly is to dissipate the heat of the high-pressure and high-temperature refrigerant gas sent by the compressor to the external space of the refrigerator 22. Through the rotation of the fan, it drives the airflow at the outdoor temperature (usually around 35 degrees C) to cool the refrigerant gas passing through the condenser, transforming it from a high-pressure and high-temperature gaseous state to a high-pressure and normal-temperature liquid state 15.

[0003] The condenser fan assembly in the prior art needs to install and remove multiple bolts when installing and disassembling the condenser fan assembly, resulting in a waste of time during maintenance. To address the above problem, a vehicle condenser fan assembly with a speed regulating device is provided. Utility Model Content
