Eddy Current and Noise Reduction Device for Engine Cooling Fan

摘要

Purpose: To provide the vortex and noise reduction device of the engine cooling fan to guide the flow of air into the engine and the cooling fan located at a short distance to prevent the vortex flow of the air generated by the rear and the noise caused by it. The purpose is to.;Configuration: To this end, the present invention includes a cooling fan (5) for cooling the water circulated by the radiator (3) to maintain the proper temperature of the cooling water heated and forced circulation by the engine (1), and the center of the cooling fan ( It is connected to 5a) and provided with a conical guide 11 formed radially extended toward the engine, to smoothly guide the flow of air flowing into the cooling fan.;Effect: Accordingly, the guider smoothes the flow of air generated at the inlet of the cooling fan to prevent vortex flow and minimize the cooling noise.
