Abstract
Range hood volute design unreasonable will produce uneven wind noise,thus affecting the product's psychological acoustics comfort.In this paper,the design method of centrifugal volute has been introduced,and the causes of the uneven wind of the centrifugal volute are analyzed.Then through numerical analysis the optimal design scheme of weakening the centrifugal volute uneven wind has been proposed.The measured data show that the new design volute average sound pressure level reduced by 1.2dB (A) and the sound of uneven wind has been improved,while maintaining the outlet flow and the total pressure of the outlet.关键词
