Discussion on the Influence of the Smoke Hood Shape on the Negative Pressure Zone
The smoke hood is an important component of the range hood,which can change the volume of the intake area and guide the oil smoke.This article first obtains performance characteristic data of a certain model of range hood through testing equipment,and then uses software to simulate different shapes of smoke collecting plates;Finally,the results from the air inlet area indicate that adding side wings to the smoke hood can move the negative pressure area downwards and increase the flow rate.The opening angle of the smoke hood will have a critical value,and even if the angle is increased,the negative pressure and flow rate in the air inlet area will not change significantly.This provides a numerical basis for the design and optimization of the smoke hood of a range hood.
