The using method of above-mentioned distributor is for passing through to adjust through hole 2 adjustable indexs of through hole 2 on tubular body 1 different parts on tubular body 1 sidewall, adjust the fluid flow at this position, be arranged in tubular body 1 each branch road pipeline fluid dispense flow rate on every side thereby reach to adjust.Wherein the pore size on tubular body 1 sidewall can be set at the identical or different aperture of size according to actual conditions, and density degree can be set at even distribution or uneven distribution.The sendout of each loop current can be by adjusting the aperture of through hole 2 in this loop, and the adjustable index of through hole 2 comprises that characteristic, distributor length, distributor material and the surface appearance of the flow direction, the fluid of stream flow velocity, the fluid of cross-sectional area, through hole 2 densitys, through hole 2 characteristics, dispenser shape, the fluid of through hole 2 wait and satisfies the distribution requirements of system to discharge.For a certain equipment (as air-conditioning unit or plate type heat exchanger etc.) that needs water flow to distribute, water flow and flow velocity remain essentially in the certain limit (the same order of magnitude), and a series of inhomogeneous through hole 2 that distributor itself carries, different through holes 2 total sectional areas by different dispensing sections come equalizing system to reach the configuration of demand assigned optimization.Pore size on this distributor can be set at the identical or different aperture of size according to actual conditions, and density degree can be set at even distribution or uneven distribution.The sendout of each loop current can be by adjusting through hole 2 in this loop aperture (cross-sectional area, aperture etc.), through hole 2 densitys (inhomogeneities), through hole 2 characteristics (as circular hole, square hole etc.), dispenser shape (as column, plane etc.) wait and satisfy the distribution requirements of system discharge.
Described through hole 2 characteristics are meant the shape of through hole 2, comprise circle, ellipse, square hole, irregularly-shaped hole.Dispenser shape comprises and adopts cylindric, flat column, round pie.Because the resistance that adopts the shape convection cell of difform through hole 2 and distributor to be produced is different with state of disturbance, the through hole 2 by adopting above-mentioned different structure and the distributor of shape are to obtain the fluid distributor of multiple different performance.Be connected to the branch body structure between distributor and the fluid circulating system, also can be structure as a whole.Be to use distributor, and satisfy the required flow of each branch road or system is reached by the characterisitic parameter that changes distributor and distribute rationally.Distributor can be made single assembly so that be installed on the equipment that needs the current distribution, also can make integral body with the equipment that needs assignment of traffic, can be with reference to the simple examples of figure 1～3.
Operation principle of the present invention: for a certain equipment (as unit or plate type heat exchanger etc.) that needs flow distribution of fluid, discharge and flow velocity remain essentially in the certain limit, and a series of inhomogeneous through hole 2 that distributor then carries by itself comes equalizing system to reach the configuration of demand assigned optimization.Pore size on this distributor can be set at the identical or different aperture of size according to actual conditions, and density degree can be set at even distribution or uneven distribution.Relating to parameters such as the aperture (cross-sectional area) of through hole 2, through hole 2 densitys, distributor aperture, dispenser shape in the sendout of each loop fluid and this loop.During present flow distributor has been used and has been distributed with the current of plate type heat exchanger, because the through hole 2 sectional area summations of distributor are much larger than the sectional area of water main own, therefore two resistances that produce can be ignored, distributed uniform mainly relies on the total sectional area of each dispensing section through hole 2 to decide, and promptly decides the degree of irregularity of each dispensing section fluid flow by the inhomogeneities of through hole 2; Rather than come balanced by the capillary resistance that through hole 2 produces.
1. the aperture of through hole 2 (cross-sectional area) can be adjusted according to the actual requirements in the distributor.Demand is big, then the hole can open bigger, demand is little, smaller (macropore and through hole 2 apertures are substantially at the same order of magnitude) that can open.In this distribution method, because the sectional area summation of through hole 2 is much larger than the sectional area of itself being responsible for, therefore the resistance that produces can be ignored; The uniformity of distributing mainly relies on the total sectional area of each dispensing section through hole 2 to decide, rather than comes balanced by the resistance of through hole 2.
2. the density of through hole 2 can be adjusted according to the demand of actual fluid flow in the distributor.Demand is big, then the hole can open more; Demand is little, and that can open is few; The through hole 2 of distributor can be different shape such as circular, square.
3. the aperture of distributor is determined by actual demand, and is relevant with the space of distributing.If conditions permit can be carried out secondary distribution (as shown in Figure 3) in the space between distributor and distributor and each distribution openings.
4. the shape of distributor can be made different shape, as column (cylindrical, square column type), round pie etc., opens hole 2 on the distributor surface and distributes.
5. if the rate of flow of fluid variation is too big, the size in each hole and density etc. then also will be along with variations.
6. fluid behaviour, distributor material and surface appearance then need to consider its physical property and chemical property.
