Description
Technical field
Strengthening heat convection type diversity water apparatus for a kind of cold source machine room of the present invention.
Background technology
Minute/water collector is that various Cooling and Heat Source machine rooms are realized house steward and the necessary equipment that each subregion arm divides/confluxes, and uses very extensive.But, conventional minute/water collector function ratio is more single, the effect of only having played minute/having confluxed.
Meanwhile, in various Cooling and Heat Source machine rooms, often need to use various heat exchangers, conventional plate type heat exchanger and the shell-and-tube heat exchanger of comprising.The major defect of plate type heat exchanger is: plate face seal perimeter is long, easily leaks.Be subject to the restriction of gasket material heat resistance, serviceability temperature can not be too high simultaneously.Because spacing between plate type heat exchanger two plates is too little, fluid resistance is large again, easily stops up.And plate face is thinner, need to use anti-corrosion alloy manufacture, avoid using for a long time corrosion failure.And shell-and-tube heat exchanger volume is large, floor space is larger, and unit heat exchange amount metal wastage is high.
In various Cooling and Heat Source machine rooms, owing to strengthening the power consumption of the cold/heating agent delivery pump of supply backwater temperature difference minimizing, so various large temperature difference system is widely adopted.Because warm extent is the key factor that affects the heat exchange amount of heat exchanger, these larger temperature difference, for using the heat-exchanger rig of simple structure, lower resistance to carry out auxiliary heat-exchanging or carrying out remaining hot/cold and reclaim, provide condition.
Summary of the invention
The object of this invention is to provide strengthening heat convection type diversity water apparatus for a kind of cold source machine room, the deficiency existing to overcome currently available technology.
The object of the invention is to be achieved through the following technical solutions:
Strengthening heat convection type diversity water apparatus for a kind of cold source machine room, comprise cylindrical shell, described cylindrical shell middle part is provided with the first maintenance flange, the two ends of cylindrical shell are respectively equipped with cylindrical shell end cap, cylindrical shell and cylindrical shell end cap junction are provided with the second maintenance flange, inner barrel is provided with some corrugated stainless steel tubings, wherein between adjacent corrugated stainless steel tubing, by bellows segmentation flange and bellows, strengthening connecting rod connects, between corrugated stainless steel tubing and cylindrical shell, by some limiting brackets, fix, the corrugated stainless steel tubing that is wherein positioned at inner barrel two ends connects respectively corrugated pipe connector, corrugated pipe connector is connected with heat exchanging pipe through cylindrical shell end cap, the end face at described cylindrical shell middle part is provided with water-main, and the both sides of water-main are evenly distributed with some branched pipes, and water-main and branched pipe all stretch in cylindrical shell, and bottom surface and the corresponding section, water-main position at cylindrical shell middle part are provided with discharge opening.The two ends, left and right of described cylindrical shell are respectively equipped with thermometer boss and pressure gauge connection near the second maintenance flange.It is all different that described water-main stretches into the distance that distance between one end in cylindrical shell and corresponding corrugated stainless steel tubing and each branched pipe stretch between one end in cylindrical shell and corresponding corrugated stainless steel tubing.Distance between described water-main and adjacent branched pipe and the distance of each adjacent branched pipe are all different.The diameter of described corrugated stainless steel tubing is less than or equal to 1/2 of barrel diameter.
Beneficial effect of the present invention is:
1, have that a device is dual-purpose, cost performance is high: the present invention not only has the basic function of conventional minute/divide/afflux of water collector, also there is heat exchange function, one device is dual-purpose, cost performance is high, especially in the reducing energy consumption of various buildings that comprises large public building, can use existing divide/water collector cylindrical shell to carry out process and remould at conditioning in Transition Season, cost-saving.
2, good effect of heat exchange: the total pipe fluid of the present invention branches to each arm or a pipe fluid confluxes to house steward's process, forms divergence form streamline, skims over the corrugated surface that bellows rises and falls, and has strengthened the heat convection with bellows.And corrugated stainless steel tubing heat conductivility is good, unfolded surface is long-pending large, whole device good effect of heat exchange.
3, little, the reasonable diffluence of flow resistance: because house steward import/export is arranged in cylindrical shell middle part, divide/conflux even.And because intermediate manifold fluid is shunted (or two side branch fluids collaborate to intermediate manifold) to two side branch, cylindrical shell cross section maximum stream flow is greatly reduced.When both sides branched pipe load full symmetric is arranged, section maximum stream flow can be reduced to 50%; Even the basal area that bellows is occupied deduction, average flow section speed of the present invention is still significantly less than the divide/water collector of routine that inclined to one side side is arranged house steward, divide/water collector of the routine that approaches center arrangement house steward; In cylindrical shell, flow resistance is little, and shunting rationally.Barrel diameter and bellows diameter can be adjusted according to actual demands of engineering; For avoiding shunting uneven, and strengthen heat exchange, inlet/outlet house steward and and the cylindrical shell of go out/water inlet pipe in oral area be arc, and all insert cylindrical shell certain depth, each pipeline insertion depth is different, different from the spacing of bellows, oral area coefficient of partial resistance is different.The concrete degree of depth of inserting according to engineering application state, is determined by Fluid Mechanics Computation analog computation, is guaranteed the flow reasonable distribution of each branch.
4, manufacture installation and maintenance easy: manufacture or be similar to minute/water collector of reforming technology, simple; Corrugated stainless steel tubing and cylindrical shell spacing are large, less scaling, should not stop up; Cylindrical shell end cap place is all connected by dismountable flange with cylindrical shell middle part, makes whole heat-exchanger rig be easy to dismounting, safeguard and maintenance.
5, save space: take former minute/water collector space, save machine room space.
6, can carry out selective heat exchange: because the branched pipe access position of cylindrical shell is different with house steward's distance, in the cylindrical shell of each branch fluid, heat exchange streamline length is different, and the heat exchange amount of each minute branch road there are differences; And the fed distance of each minute branch road cold/heating agent is different, in course of conveying cold/heat loss is different.When using this heat-exchanger rig, can fed distance is far away, cold/heat loss larger branched layout, divide/catchmenting cylindrical shell apart from house steward's access point at a distance, increases this branch fluid streamline length, with the cold/heat loss of increase balance conveying of heat exchange amount.
