Description

Technical Field

[0002] The automotive cooling fan is an important part of the automotive cooling system. Its function is to allow more air to flow through the radiator, enhance the heat dissipation capacity of the radiator, speed up the cooling of the coolant, and allow more air to flow through the engine to take away the heat emitted by the engine. At the same time, the performance of the fan directly affects the heat dissipation effect of the engine, and thus affects the performance of the engine. If the fan is not selected properly, it will lead to insufficient or excessive cooling of the engine, causing the engine working environment to deteriorate, and thus affecting the performance and service life of the engine. In addition, the power consumed by the fan accounts for about 5% to 8% of the engine output power. In the pursuit of environmental protection and low energy consumption, fans are also increasingly attracting attention.
