Calculation method of single-fan double-outlet air flue of air purifier and structure of single-fan double-outlet air flue

Abstract

The invention discloses a calculation method of the single-fan double-outlet air flue of an air purifier and a structure of the single-fan double-outlet air flue. The calculation method is characterized in that R[Phi] is equal to R2(1+m[Phi]) ([Phi] is greater than or equal to 0 and is less than or equal to [Pi]), and R[Phi] is equal to R2[1+m([Phi]-[Pi])] ([Phi] is greater than or equal to [Pi] and is less than or equal to 2[Pi]), wherein R[Phi] is the radius of the inner wall of the outlet air flue, R2 is the external dimeter of a wind wheel vane, m is equal to Qn / 2[Pi]BC2uR2, Qn is a design flow, B is the height of the outlet air flue, and C2u is circumferential speed after airflow leaves a vane channel outlet. Since the tension degree of an air flue curve is calculated according to the rated blast capacity of a centrifugal fan, two rotary and centrosymmetric Achimedean spirals are adopted to construct a double-outlet air flue curve model. The air flue model has the characteristics that the on-way resistance loss of airflow is reduced to a maximum degree, outlet air returning and airflow self-circulation are avoided, and the air inlet blast capacity and the air inlet efficiency of the purifier can be improved.

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 single fan and double outlets. Background technique [0002] Such as 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 purifier single fan double outlet air duct with simple calculation and scientific air duct curve model. 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 single fan and double outlet a...
