Fluid distributor

Abstract

The invention provides a fluid distributor comprising a distribution pipe and a fluid supply pipe, wherein two ends of the distribution pipe are closed, the side wall of the distribution pipe is provided with a plurality of through holes which are communicated with branches and used for distributing fluid to each branch; the fluid supply pipe is communicated with the distribution pipe through a connector arranged at the middle position of the upper part of the distribution pipe and used for distributing fluid to two sides of the distribution pipe; the distribution pipe and the fluid supply pipe are arranged in parallel, the connector divides the distribution pipe into a first part and a second part which are mutually communicated, and the density of a plurality of through holes positioned in the first part and the second part is gradually reduced from the connector towards two ends; the connector forms an acute included angle with the first part and forms an obtuse included angle with the second part; and the sum of the sectional areas of the plurality of through holes in a certain region of the first part is smaller than the sum of the sectional areas of a plurality of through holes in the symmetrical region of the second part. The fluid distributor provided by the invention can guarantee the uniform distribution of fluid flow.

Description

technical field [0001] The invention relates to a fluid distribution device, which belongs to the field of fluid distribution. Background technique [0002] When the fluid flows in the pipeline, it usually needs to distribute the flow according to the demand, and the unbalanced flow distribution will often make the system unstable. In the plate heat exchanger of the air conditioning system, because the plate heat exchanger is larger and thicker, the flow velocity of the fluid when it first enters the plate heat exchanger is relatively large, and it passes through the interface part quickly, resulting in less fluid flow distributed by the inlet part. Most of the fluid accumulates inside the plate heat exchanger, making the flow into each plate unbalanced, resulting in insufficient heat exchange. [0003] In order to solve the above problem of uneven flow distribution, Chinese patent document CN101008560A discloses a fluid distribution device, such as figure 1 As shown, its ...
