Description
Technical field
The invention belongs to heat-exchange system field, the fluid distributor that particularly a kind of heat exchange efficiency is higher.
Background technology
Two-phase fluid maldistribution is the main cause causing heat exchanger heat-transfer performance sharply to decline, and arranges at plate-fin heat exchanger two phase flow entrance the engineering method that distributor is a kind of improvement partition characteristic widely adopted.And existing plate type heat exchanger, particularly comparatively large thicker plate type heat exchanger, the situation causing assignment of traffic uneven because dispenser designs is unreasonable is comparatively serious.This is because the flow velocity when just entering plate type heat exchanger of the fluid in supervisor is larger, quickly move through intake section, the fluid flow causing the heat exchanger plates place of intake section to distribute is less, most fluid all accumulates in the inside of plate type heat exchanger, thus the mass flow discrepancy entered between each plate is weighed, and then cause heat exchange insufficient, affect the operation of whole air-conditioning system.
For solving the problems of the technologies described above, Chinese patent document CN101008560 discloses a kind of fluid distributor, this distributor is arranged at the part that fluid main line is combined with each bye-pass, distributor is the main body of tubulose, shaping some through holes on the sidewall of tubular body, it produces flow-disturbing effect by arranging multiple through hole, can realize the effect of the dispense flow rate of equilibrium distributor.But due to heat exchanging fluid normally gas-liquid mixed refrigerant, gas relative liquid flow velocity is very fast, and cause gas first to enter in heat exchanger fin by through hole, visible, the fluid distributed uniform degree of above-mentioned distributor still has much room for improvement.
Summary of the invention
For this reason, technical problem to be solved by this invention is the distributor that provides a kind of fluid distributed uniform degree higher.
For solving the problems of the technologies described above, a kind of fluid distributor of the present invention, it comprises, the distributing pipe that one end open one end is closed, the tube wall of described distributing pipe forms some flow-disturbing holes, outside coated at least one deck shunt cylinder of described distributing pipe, described shunt cylinder spreads all over and has some tap holes, and the aperture of described tap hole is between 0.1-1mm.
Described shunt cylinder is flexible screen pack, and the mesh aperture of described screen pack is 0.2-0.5mm.
Described shunt cylinder is made up of sheet metal, and on described sheet metal, shaping some apertures are the described tap hole of 0.5-1mm.
The described shunt cylinder of some layers is coated with outside described distributing pipe.
Described distributing pipe upper part is coated with described shunt cylinder, and described shunt cylinder is positioned at the surface in described flow-disturbing hole, completely coated to described flow-disturbing hole.
Described distributing pipe upper part is coated with described shunt cylinder, and described shunt cylinder is positioned at the surface in the described flow-disturbing hole of part.
Along described distributing pipe open side to described distributing pipe closed side, the distribution density in described flow-disturbing hole reduces gradually.
The total sectional area in described flow-disturbing hole is greater than the sectional area of described distributing pipe.
Technique scheme of the present invention has the following advantages compared to existing technology:
(1) on distributor of the present invention on the distributing pipe with flow-disturbing hole coated at least one deck shunt cylinder again, shunt cylinder spreads all over and has some tap holes, the aperture of tap hole is between 0.1-1mm.Gas-liquid two-phase refrigerant fluid under the flow-disturbing effect in the flow-disturbing hole of distributing pipe, the balanced flow entering each branch road from distributing pipe; And under the effect of tap hole on shunt cylinder, air pocket is carried out fragmentation, make the fluid entering branch road more even.
(2) shunt cylinder on distributor of the present invention selects aperture to be the screen pack of 0.1-1mm, and its structure is simple, and installation cost is lower, and can realize the effect of current-sharing.
(3) shunt cylinder on distributor of the present invention can select full clad type also can select part clad type according to actual flow distribution requirements, and part is coated to be coated on the flow-disturbing hole of distributing pipe by shunt cylinder part.

Fig. 1 is fluid distributor structural representation of the present invention;
Fig. 2 is the board-like shunt cylinder structural representation of metal foil of the present invention;
Fig. 3 is the shunt cylinder structural representation of filter screen type of the present invention.
In figure, Reference numeral is expressed as: 1-distributing pipe, 11-flow-disturbing hole, 2-shunt cylinder, 21-tap hole.
Detailed description of the invention
Below with reference to accompanying drawing, following examples are used to be further elaborated the present invention.
Fig. 1 is a kind of fluid distributor disclosed by the invention, and it comprises, the distributing pipe 1 that one end open one end is closed, and wherein, described openend is fluid intake; The tube wall of described distributing pipe 1 forms some flow-disturbing holes 11, distributes rationally for equalizing system to reach distribution according to need, prevent the flow of entrance side branch road few, middle flow is many; Outside coated at least one deck shunt cylinder 2 of described distributing pipe 1, described shunt cylinder 2 spreads all over and has some tap holes 21, and the aperture of described tap hole 21 is between 0.1-1mm.Under the effect of tap hole, air pocket is broken into the minute bubbles consistent with tap hole pore size, makes the fluid entering branch road more even.
As shown in Figure 2, described shunt cylinder 2 is made up of sheet metal, and on described sheet metal, shaping some apertures are the described tap hole 21 of 0.5-1mm.
As shown in Figure 3, described shunt cylinder 2 can also be flexible filter net, and the mesh aperture of described screen pack is 0.2-0.5mm.
In order to the gaseous fluid making to enter branch road is tricklelyer broken, preferably, by being coated with the described shunt cylinder 2 of some layers outside described distributing pipe 1, as wrapped up screen pack as described in some layers, it is through the filtration of multiple filtration net, can make bubble breaking obtain thinner evenly.
In the present invention, described distributing pipe 1 wholely can be coated with described shunt cylinder 2, also partly can be coated with described shunt cylinder 2, described shunt cylinder 2 is positioned on the described flow-disturbing hole 11 of described distributing pipe 1, by completely coated for described flow-disturbing hole 11.
In other embodiments, prize shunt cylinder 2 part can also be selected to be coated on described distributing pipe 1 according to assignment of traffic, and select flow-disturbing hole 11 described in covered section.
In order to strengthen flow-disturbing effect, along described distributing pipe 1 open side to described distributing pipe 1 closed side, the distribution density in described flow-disturbing hole 11 reduces gradually.Like this, at the fluid of entrance side under the larger flow-disturbing hole 11 of density acts on, the flow being dispensed to branch road improves.In addition, can also by the total sectional area in described flow-disturbing hole 11 be set to the sectional area being greater than described distributing pipe 1, above-mentioned flow-disturbing hole 11 can be made like this to carry out, in the process that fluid redistributes, excessive resistance can not being produced.In addition, by adjusting the shape in described flow-disturbing hole 11, and the shape of distributor, control dispenser is in the assignment of traffic of different branch.
In heat-exchanger rig, the fluid after above-mentioned fluid distributor flows to identical with another kind of heat exchanging fluid.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
