Problems solved by technology

This means that the fluid flow rate is not uniform
In the field of HVAC, if this part of the fluid is directly sent into the room, it will affect the indoor air distribution, so that the actual indoor comfort cannot meet the design requirements

Abstract

The invention discloses a rectangular wind-pipe separate converging-rectifying three-way pipe which comprises a first inlet segment, a second inlet segment and an outlet segment, wherein the extension lines of the first inlet segment and the second inlet segment form an included angle of 90 degrees, the lower end of the first inlet segment is connected with a linear converging segment, one side of the second inlet segment is connected with a flexural converging segment, the linear converging segment and the flexural converging segment are both connected with a buffer segment, and a rectifyingsegment connected with the outlet segment is arranged below the buffer segment; and rectifying vanes are arranged at the upper end in the rectifying segment, and each rectifying vane is provided witha guide vane to divide the rectifying segment into five fluid passages with equal size. The unique design of the invention eliminates the speed layering formed after a fluid passes through the rectangular wind-pipe separate converging three-way pipe to finally achieve the purpose of rectifying the fluid after passing through the rectangular wind-pipe separate converging three-way pipe.

Description

technical field [0001] The invention relates to a confluence tee component, in particular to a rectangular air duct separation type confluence and rectification tee. Background technique [0002] The confluence tee is a very common pipe fitting that changes the flow direction of the fluid and merges in the fluid machinery of HVAC power. When the curved pipe section (before the end of the bend) transitions to the straight section of the pipe, the pressure on the outer arc surface increases and the pressure on the inner arc surface decreases. Therefore, the flow velocity of the fluid at the outer dome will decrease, while the flow velocity of the fluid at the inner dome will correspondingly increase. Therefore, the diffusion effect appears near the outer arc surface, while the contraction effect appears near the inner arc surface. When the fluid transitions from a straight pipe section (after turning) to a curved pipe section, the opposite phenomenon occurs, that is, a diffu...
