Abstract
The utility model discloses a fluid equipartition structure that is used for board -like air cooler core to enter mouth, including takeover, semicircular arch, end plate, curb plate, this equipartition structure includes the carriage, whole rigid coupling in semicircular arch bottom behind a plurality of water conservancy diversion pieces of installation in this carriage. The water conservancy diversion piece uses carriage length direction's central line just to arrange to this symmetry axis inclination as the symmetry axis. The inclination of water conservancy diversion piece is 5~25. The water conservancy diversion piece is equidistant arranging not, from carriage length direction's central line to both sides grow gradually. The utility model provides a core inlet fluid equipartition structure, simple manufacture can improve the fluid and in core entrance maldistribution problem, improve heat transfer performance, avoids the core tip because the temperature stress difference causes fracture, the whole life of improve equipment.
Description
Technical field
This utility model is related to plate air cooler technical field, and in particular to a kind of for plate air cooler plate beam entrance
Uniform fluid distribution structure.
Background technology
Air cooler is a kind of to use air as the heat exchanger that material is cooled down by cold medium, it is adaptable to which low temperature position medium is cold
The solidifying, occasion of cooling.Wherein plate air cooler adopts plate heat transfer technology, replaces traditional finned tube with corrugated plating, empty with environment
, used as cooling medium, horizontal being plunderred make outside corrugated plating high-temperature technology fluid in plate beam and cooled down or condensed for gas.Plate air cooler has
Heat transfer efficiency height, low pressure drop, compact conformation, less scaling, maintenance be the features such as facilitate, be widely used in the energy, oil,
The fields such as chemical industry, metallurgy, environmental protection.
In plate air cooler design process, assume that hot fluid is uniformly distributed in each plate pipe.In fact, hot-fluid
Body is by taking over into semicircular arch bobbin carriage, then flows into plate pipe flow road.During being somebody's turn to do, flow of fluid section exists
The phenomenon of diminution, the equivalent diameter of runner frequently change, and realize that fluid is impossible, Jing in the distribution of plate pipe inner homogeneous
Can often cause bigger than normal near thermal fluid flow at adapter central projection in plate beam entrance end, near bobbin carriage end plate side hot fluid stream
Amount phenomenon less than normal, causes both sides plate different from the thermal (temperature difference) stress of center panel, causes both sides plate end to be susceptible to become
Shape, when bias current is serious, easily there is cracking in both sides plate end.
The common method for improving fluid distrbution at present inside semicircular arch bobbin carriage is exactly to arrange to divide inside semicircular arch bobbin carriage
Fabric swatch, opens up multiple manholes on distribution grid.It is applied to pipe type heat transfer element fluid distrbution more the method, and causes hot-fluid
Body pressure drop increases more；The cross section of fluid channel of plate heat transfer element is strip, and original distribution grid is more difficult to meet multiple elongated plates
The Spreading requirements in pipe flow road.
Utility model content
The purpose of this utility model is to provide a kind of uniform fluid distribution structure for plate air cooler plate beam entrance, is passed through
Flow deflector structure is set inside semicircular arch bobbin carriage, makes hot fluid be evenly distributed to each plate pipe flow road of plate beam as far as possible,
Reliable guarantee is provided for plate Shu Chuanre.
This utility model is achieved through the following technical solutions above-mentioned technical purpose：
A kind of uniform fluid distribution structure for plate air cooler plate beam entrance, including adapter, semicircular arch, end plate, side plate, should
Distribution equalizing structure includes carriage, and the support inframe is integrally fixed in semicircular arch bottom after installing some flow deflectors.
The flow deflector is in tilted layout with the centrage of carriage length direction as axis of symmetry and to the axis of symmetry.
The angle of inclination of the flow deflector is 5～25 °.
The flow deflector is arranged for unequal-interval, is become larger to both sides from the centrage of carriage length direction.
This utility model makes hot fluid be evenly distributed to as far as possible by arranging flow deflector structure inside semicircular arch bobbin carriage
Each plate pipe flow road of plate beam, provides reliable guarantee for plate Shu Chuanre；Plate beam end is avoided to cause due to thermal (temperature difference) stress difference
Cracking, improves equipment whole service life.And make simple, and structure input itself is nor very big, be it is a kind of it is direct,
Economic fluid distrbution optimization method.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Side views of the Fig. 2 for Fig. 1；
Fig. 3 is welded with the carriage structural representation of flow deflector for this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings utility model is further illustrated.
Refering to Fig. 1, Fig. 2, Fig. 3, a kind of uniform fluid distribution structure for plate air cooler plate beam entrance, including adapter 1, half
Circular arch 2, end plate 3, side plate 4, flow deflector 5, carriage 6.The fluid channel dimensions constituted according to semicircular arch 2, end plate 3, side plate 4 add
Work goes out a carriage 6, and 6 length of carriage is equal to 3 clear spacing of two end plates, and width is equal to 4 clear spacing of biside plate, and height is about
12mm, the surrounding wall thickness of carriage is 5mm.Flow deflector 5 is welded on inside carriage 6, the width about 12mm of flow deflector 5, it is thick
Spend for 3mm.6 cross central line of carriage（The centrage of flow deflector length direction）The flow deflector 5 of both sides along carriage 6 laterally in
Heart line is arranged symmetrically, and wherein left side flow deflector 5 is tilted to the right arrangement, with vertical direction in 5～25 ° of angles, right side flow deflector 5 to
Left bank arranges that, with vertical direction in 5～25 ° of angles, the wherein angle number of degrees can be adjusted according to thermal fluid flow；And lead
Flow 5 is to arrange perpendicular to 4 unequal-interval of side plate, becomes big near 3 side flow deflector of end plate, 5 spacing, near adapter 1 at 7 end of plate beam
At portion's projection, 5 spacing of flow deflector diminishes.It is arranged so as to give full play to the drainage for inclining flow deflector 5, is prevented effectively from and leans on
Plate pipe and the problem near plate pipe internal flow skewness of the adapter 1 at 7 end projection of plate beam at proximal plate 3.
The carriage structure welding for being welded with flow deflector 5 is fixed on inside the fluid passage that end plate 3 and side plate 4 are formed,
And it is welded with the support mount structure of flow deflector 5 and is located at 2 bottom section of semicircular arch.The overall one kind that constitutes is used for plate air cooler
The uniform fluid distribution structure of plate beam entrance.
Semicircular arch bobbin carriage is removable structure, during overhaul of the equipments, can take bobbin carriage apart, flow deflector 5 and carriage 6 are entered
Row steam blowing and mechanical cleaning, remove 5 impurity of flow deflector, it is ensured that equipment is run reliably and with long-term.
