Description

Technical Field

[0001] The utility model belongs to the technical field of automobile cooling fans and relates to a fan blade structure of an automobile cooling fan. Background Art

[0002] Cars are the most commonly used means of transportation in our daily lives. Cars bring us a lot of convenience. Let us get rid of the pain of waiting for cars and squeezing subways, and at the same time, there is also an excellent sense of comfort. The cooling system of a cold car completes the liquid circulation through pipes and channels in the engine. When the liquid flows through the high-temperature engine, it absorbs heat, thereby reducing the temperature of the engine. After the liquid flows through the engine, it turns to the heat exchanger, and the heat in the liquid is dissipated into the air through the heat exchanger. Air cooling Some early cars used air cooling technology, but modern cars cool the cylinders through aluminum sheets attached to the surface of the engine cylinders. Powerful fans blow air to these aluminum sheets, dissipating heat into the air, thus achieving the purpose of cooling the engine.

[0003] Most of the existing fans used for automobile cooling are installed at one end of the rotating shaft of the motor, and the fan blades inside are directly installed in the inner fan hoop with intervals. When the motor drives the fan to rotate, a rapidly flowing airflow is formed. The different shapes of the internal equipment cause the airflow direction to be disordered. The fan blades shake to varying degrees due to the disturbance of the turbulent airflow, causing the fan blades to be unevenly stressed and deformed. Utility Model Content
