Study on standardized application of range hood fan platform
The cooperation between the fan and the rack determines the performance level of the range hood,in order to study the application of the standardization of the fan platform,the rack size of the range hood,the fan mounting position,and the different appearance patterns were analyzed through simulation and experimentation,and the rack size and mounting position adapted to the fan were obtained,and a combined design scheme of the fan rack was formed,which improves the flow efficiency inside the rack and balances the front and rear air intake uniformity of the fan,thereby reducing the required rotational speed at the same air flow,and improves the overall noise.Compared to the original rack assembly,the noise reduction for the same airflow is more than 2 dB(A)in both appearance patterns.
