Description

Technical Field

[0001] The utility model relates to the technical field of condensing fans, in particular to a condensing fan for an automobile air conditioner. Background Art

[0002] The automobile air-conditioning condensing fan is a vital component in the automobile air-conditioning system, which is mainly responsible for heat dissipation and cooling. It usually includes parts such as motor, fan blades, bearings, wind ring and protective cover. The motor is the power source of the condensing fan, driving the fan blades to rotate and generate strong wind force. The fan blades are the key part of promoting air flow. When they rotate at high speed, they can quickly draw the hot air in the car into the condenser, and blow the cooled air out through acceleration, thereby reducing the temperature in the car. During the operation of the automobile air-conditioning system, the refrigerant is heated and evaporated in the evaporator, and then compressed into high-temperature and high-pressure gas through the compressor, and finally flows into the condenser. At this time, the condensing fan starts to work, and the strong wind force it generates accelerates the air flow around the condenser, effectively cooling and compressing the high-temperature and high-pressure refrigerant in the condenser into liquid, thereby completing the refrigeration cycle of the automobile air-conditioning. In short, the automobile air-conditioning condensing fan creates a cool and comfortable driving environment for drivers and passengers with its efficient and stable performance.

[0003] Car air conditioning requires a condensing fan. Existing condensing fans are usually installed manually using bolts. Manual installation is time-consuming and labor-intensive. At the same time, long-term use of moisture can easily cause the bolts to rust, making it more complicated to disassemble the bolts, reducing the stability and safety of the fan.

[0004] Therefore, it is necessary to redesign the condensing fan of the automobile air conditioner to effectively prevent the existing condensing fan from being usually installed manually using bolts. Manual installation is time-consuming and labor-intensive. At the same time, long-term use of moisture can easily cause the bolts to rust, making the bolt disassembly more complicated, reducing the stability and safety of the fan. Utility Model Content
