Description
Technical field
A kind of low-temperature receiver machine room of the present invention divides captation with strengthening the heat convection type.
Background technology
Branch/water collector is the indispensable equipment that various Cooling and Heat Source machine rooms are realized house stewards and each subregion arm branch/conflux, and uses very extensive.But conventional branch/water collector function ratio is more single, has only played the effect of branch/conflux.
Simultaneously, in various Cooling and Heat Source machine rooms, often need use various heat exchangers, plate type heat exchanger and the shell-and-tube heat exchanger of comprising commonly used.The major defect of plate type heat exchanger is: plate face seal perimeter is long, leaks easily.Receive the restriction of gasket material heat resistance simultaneously, serviceability temperature can not be too high.Because of spacing between plate type heat exchanger two plates is too little, fluid resistance is big, easy blocking again.And the plate face is thinner, needs to use the anti-corrosion alloy manufacturing, avoids using for a long time corrosion failure.And the shell-and-tube heat exchanger volume is big, and floor space is bigger, and unit heat metal wastage is high.
In various Cooling and Heat Source machine rooms, owing to strengthen the power consumption that supply backwater temperature difference reduces cold/heating agent delivery pump, so various big temperature difference system is widely adopted.Because the size of the temperature difference is the key factor that influences the heat of heat exchanger, these bigger temperature difference are assisted heat exchange for the heat-exchanger rig that uses simple structure, lower resistance or are carried out surplus hot/cold and reclaim, and condition is provided.
Summary of the invention
The purpose of this invention is to provide a kind of low-temperature receiver machine room and divide captation, to overcome the deficiency that present prior art exists with strengthening the heat convection type.
The objective of the invention is to realize through following technical scheme:
A kind of low-temperature receiver machine room divides captation with strengthening the heat convection type; Comprise cylindrical shell, said cylindrical shell middle part is provided with the first maintenance flange, and the two ends of cylindrical shell are respectively equipped with the cylindrical shell end cap; Cylindrical shell and cylindrical shell end cap junction are provided with the second maintenance flange; Barrel is provided with some corrugated stainless steel tubings, strengthens connecting rod through bellows segmentation flange and bellows between the wherein adjacent corrugated stainless steel tubing and connects, and fixes through some limiting brackets between corrugated stainless steel tubing and the cylindrical shell; The corrugated stainless steel tubing that wherein is positioned at the barrel two ends connects corrugated pipe connector respectively, and corrugated pipe connector passes the cylindrical shell end cap and is connected with heat exchanging pipe; The end face at said 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 the cylindrical shell, and the bottom surface and the corresponding section, water-main position at cylindrical shell middle part are provided with discharge opening.The right ends of said cylindrical shell is provided with thermometer boss and pressure gauge connection respectively near the second maintenance flange place.Said water-main stretches into distance and each branched pipe between an end and the corresponding corrugated stainless steel tubing in the cylindrical shell, and to stretch into the interior end of cylindrical shell all different with the distance between the corresponding corrugated stainless steel tubing.The distance between said water-main and the adjacent branched pipe and the distance of each adjacent branched pipe are all different.The diameter of said 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 branch/water collector branch/afflux; Also has heat exchange function; One device is dual-purpose, and cost performance is high, especially in the various building energy-saving that comprise large public building are transformed; Can practice thrift cost using existing branch/water collector cylindrical shell to carry out process and remould in transition season.
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 the divergence form streamline, skims over the corrugated surface that bellows rises and falls, and has strengthened the heat convection with bellows.And the corrugated stainless steel tubing heat conductivility is good, unfolded surface is long-pending big, whole device good effect of heat exchange.
3, little, the reasonable diffluence of flow resistance:, divide/conflux evenly because the house steward import/export is arranged in the cylindrical shell middle part.And, cylindrical shell cross section maximum stream flow is significantly reduced because the intermediate manifold fluid is shunted (or two side branch fluids collaborate to intermediate manifold) to two side branch.When the both sides branched pipe is loaded complete symmetric arrangement, can the section maximum stream flow be reduced 50%; Even with the basal area deduction that bellows occupies, average flow section speed of the present invention still is significantly less than routine branch/water collector that inclined to one side side is arranged house steward, near routine branch/water collector of center arrangement house steward; Flow resistance is little in the cylindrical shell, 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, advance/outfall sewer and with the cylindrical shell that goes out/intake arm in oral area be arc, and all insert the cylindrical shell certain depth, each pipeline insertion depth is different, and is different with the spacing of bellows, oral area coefficient of partial resistance difference.The concrete degree of depth of inserting is confirmed by the Fluid Mechanics Computation analog computation according to the practical applications situation, is guaranteed the flow reasonable distribution of each branch.
4, the manufacturing installation and maintenance are easy: manufacturing or reforming technology are similar to branch/water collector, and be simple; Corrugated stainless steel tubing and cylindrical shell spacing are big, less scaling, should not stop up; Cylindrical shell end cap place all is connected through detachable flange with the cylindrical shell middle part, makes whole heat-exchanger rig be easy to dismounting, safeguard and maintenance.
5, conserve space: take former branch/water collector space and get final product, practice thrift the machine room space.
6, can carry out the selectivity heat exchange: because that branched pipe inserts the position of cylindrical shell is different with house steward's distance, heat exchange streamline length difference in the cylindrical shell of each branch fluid, each minute the heat exchange amount of branch road there are differences; And each minute branch road the fed distance of cold/heating agent different, the cold/heat loss in the course of conveying is different.When using this heat-exchanger rig, can the bigger branched layout of fed distance is far away, cold/heat loss divide/catchment cylindrical shell at a distance apart from house steward's access point, increase this branch fluid streamline length, carry cold/heat loss with the increase balance of heat.
