Abstract

The invention discloses a method for calculating double outlet air channels of double fans of an air purifier, and a structure thereof. The formula is as shown in the specification, wherein a formula as shown in the specification is the semi-diameter of the inner wall of an outlet air channel; R2 is the outside diameter of a wind turbine blade; a formula as shown in the specification is the design flow; B is the height of the outlet air channel; and C2u is the circumferential speed after airflow leaves from an air channel outlet. The tensile degree of an air channel curve is calculated according to the rated air volume of a centrifugal fan; the covering degree of a helical line is determined through analytical calculation; therefore, an air channel curve model is designed; by means of the air channel curve model, the pneumatic performance of the fan is effectively improved; the airflow resistance loss is reduced; the air return phenomenon at the outlet is avoided; and the air inlet volume and the air inlet efficiency of the purifier itself are increased.

Description

technical field [0001] The invention relates to an air purifier, in particular to a calculation method and a structure of an air purifier with double blowers and double outlets. Background technique [0002] like figure 1 As shown, the air intake air volume of the vehicle-mounted air cleaner 10 is greatly limited due to the limitation of its size. Therefore, it is necessary to optimize the flow field of the air duct as much as possible, reduce the resistance loss, reduce the return air phenomenon at the outlet, and improve the air intake efficiency and air intake volume. Contents of the invention [0003] An object of the present invention is to provide a calculation method for air purifiers with simple calculations and a scientific air duct curve model with dual fans and dual outlets. The air duct curve model of the purifier with dual fans and dual outlets. [0004] Another object of the present invention is to provide an air purifier with a double-fan and double-outle...
