Abstract

The invention relates to the technical field of fluid distribution, and discloses a flow dividing element which comprises an element body. A plurality of flow dividing through holes are distributed on the element body; the porosity of the element body is 60 percent to 78 percent; and the included angle between the axis of each flow dividing through hole and the normal of the plane where the flow dividing through hole is located is 0 degree to 15 degrees. By controlling the porosity of the flow dividing through holes and setting the forming directions of the flow dividing through holes, a better flow mixing effect can be achieved on fluid, and the fluid flowing through the flow dividing through holes can be evenly and stably mixed; the fluid distributor comprising the flow dividing element is uniform in liquid distribution, so that good uniformity and stability are achieved, and the uniformity and the stability of the fluid distributor can be even superior to the uniformity and the stability of an existing venturi distributor; and furthermore, a heat exchanger adopting the fluid distributor is uniform in flow distribution, and the energy efficiency is improved. Meanwhile, the flow dividing element provided by the embodiment of the invention is simple in structure, easy to machine and form and low in machining cost. The invention further discloses the fluid distributor.

Description

technical field [0001] The present application relates to the technical field of fluid dispensing, for example, to a flow dividing element and a fluid distributor. Background technique [0002] At present, in the refrigeration system, except for the case where the amount of cooling (heat) is very small, the heat exchanger generally adopts the form of multi-channel parallel connection to keep the refrigerant at an optimal flow rate, and at the same time, the pressure drop on the refrigerant side of the heat exchanger is limited within a certain range. , and when the refrigerant with uniform gas-liquid mixture is equally distributed to each branch, the efficient use of the heat exchanger can be ensured. When the refrigerant cannot be evenly distributed to each branch, it will cause different degrees of superheat at the outlets of each branch of each heat exchanger, and the branch with less liquid supply will enter the overheating zone prematurely, and the coefficient of the he...
