Description

Technical Field

[0001] The utility model relates to the technical field of automobile cooling fans, in particular to a cooling fan which can be quickly disassembled. Background Art

[0002] The cooling fan inside the car is a key component in the vehicle's thermal management system. Its main function is to dissipate heat by forcing air to flow when the car is running, ensuring that the engine and other key components are not damaged by overheating. These fans are usually located in the engine compartment and work in conjunction with components such as the condenser and radiator to maintain the temperature inside the vehicle within a suitable range. The operation of the cooling fan is usually controlled by the vehicle's electronic control system, which automatically adjusts the fan speed according to the engine's operating temperature and cooling requirements. In new energy vehicles, the design and function of the cooling fans may vary, but their core purpose is still to effectively manage the temperature inside the vehicle and ensure the stability and reliability of the vehicle under various operating conditions.

[0003] At present, the cooling fan inside the car performs cooling work for a long time, so the cooling fan needs to be regularly inspected and maintained to prevent damage to the cooling fan. At present, the cooling fan is generally connected to the condensation plate by multiple sets of bolts to improve the stability of installation. However, due to the large number of bolts used, when the cooling fan and the condensation plate are disassembled and separated, the multiple sets of bolts need to be unscrewed one by one, resulting in a long time to disassemble and separate them. Subsequently, when the cooling fan is inspected and maintained, the bolts still need to be screwed into the cooling fan and the condensation plate, resulting in troublesome and time-consuming disassembly and assembly of the cooling fan. Therefore, a cooling fan that can be quickly disassembled is proposed. Utility Model Content

The disassembly steps of the cooling fan 3 on the right side are the same as those of the cooling fan 3 on the left side.
