The utility model has the advantages of easy production, convenient assembly and disassembly of corrugated pipes, obviously improved the flowing condition of fluid and enhanced heat transferring effects, improved antivibration abilities of the tube bundles, labour saving, materials saving, realized support without gap, and reduced productive cost. The utility model effectively solves the problems that the corrugated pipes are clamped during the assembling and disassembling periods.
Description
The utility model relates to a kind of corrugated tube heat exchanger, and particularly a kind of rod baffle corrugated tube heat exchanger that utilizes rod baffle to realize no gap supporting heat exchanger tube also can be used for other structure heat exchanger tube heat exchanger.
The version of existing heat transmission equipment has many kinds, and traditional heat exchangers adopts light pipe, and modern heat exchanger adopts bellows to replace light pipe, reaches the purpose of augmentation of heat transfer.Heat exchanger tube in the above-mentioned various heat exchanger, no matter be light pipe, or bellows, all with certain thickness deflection plate supporting heat exchanger tube.In accordance with regulations, be bearing in reliably on the bellows crest, require the accumulated error of the whole length bellows pitch of waves to be less than or equal to half of deflection plate thickness for making the deflection plate pore.But the restriction of being created conditions is difficult to reach requirement, and the bellows supporting is unreliable, reduces tube bank antivibration ability.In addition, the installation accuracy of deflection plate is had relatively high expectations, otherwise mounting pipe or when pipe maintenance are blocked by the hole easily.If increase deflection plate thickness, make thickness of slab greater than the bellows pitch of waves, bellows any position in housing can both be contacted reliably with deflection plate.Though this method supporting is reliable, because deflection plate thickness is excessive, has increased material consumption and labor content, has strengthened manufacturing cost.Deflection plate also can make fluid produce leakage current, short circuit, dead band etc. in housing to be unfavorable for the problem of conducting heat.
The purpose of this utility model provides a kind of rod baffle corrugated tube heat exchanger, it is easy to manufacture, the loading, unloading bellows is convenient, compared with prior art, the problem of being blocked when effectively solving the loading and unloading bellows of its existence is obviously improved fluid flow state and augmentation of heat transfer effect, realize the supporting of no gap, improved the antivibration ability of tube bank, saving of labor, material-saving reduce manufacturing cost.
The purpose of this utility model is achieved in that this device comprises that housing and the tube bank supporting mass that links to each other with the spacing bar are assembled in the tube bank of the corrugated tube on the forward and backward tube sheet in the housing, wherein restraining supporting mass is the lamellar formula rod baffle assembly that has embedding mouth groove, and each rod baffle is rabbeted mutually and is integral formula square net or network shape supporting mass.
Because the utility model is made conditionality at traditional baffle plate type supporting mass that corrugated tube in the existing heat exchanger exists, the corrugated tube crest fall less than in the pore of deflection plate and the forfeiture supporting role, under the impact of media flow, easily produce vibration, make the problem of damaged tubular, and design the supporting mass that makes new advances.It adopts the lamellar formula rod baffle that has embedding mouth groove to rabbet mutually, forms peculiar supporting mass, so can realize not having the gap supporting, improves the reliability of supporting.The supporting mass rod baffle assembly of this structure compared with prior art, not only the accuracy of manufacture is less demanding, and is easy to manufacture, and the loading, unloading corrugated tube also is difficult for being stuck, very convenient.Improving the supporting reliability with the thickening deflection plate in addition compares, with the most frequently used crest is that the corrugated tube of Φ 42mm, pitch of waves ω=25mm is an example, angle α=90 ° setting by the interlocking grid, Master Cost only be its 40%, machining amount reduces 92%, so saving of labor, material-saving reduce manufacturing cost.As with angle α=60 ° setting, then saving of labor, material-saving are more remarkable.This version adopts the special material supporting mass for those, as precious materials, and the deflection plate that difficult-to-machine material is made, its manufacturing cost reduces more obvious.In addition, this supporting mass rod baffle assembly not only can realize not having the gap supporting, improve corrugated tube antivibration ability, and flow field direction is a longitudinal stream, also obviously improved fluid flow state, thereby be unfavorable for the factor of conducting heat really having realized genuine augmentation of heat transfer from eliminated leakage current, short circuit, dead band etc. at all.
Below in conjunction with accompanying drawing the utility model is further described.

Describe concrete structure of the present utility model in detail according to Fig. 1-6.This device is that example is described with the shell-and-tube corrugated tube heat exchanger.It comprises the housing 7 that has front header 1, rear header 10, bearing 12 and tube side inlet 2, tube side outlet 13, shell side inlet 11, shell side outlet 4, the tube bank supporting mass rod baffle assembly 8 that links to each other with spacing bar 6, is assembled in the housing 7 corrugated tube on front tube sheets 3, the back tube sheet 9 and restrains parts such as 5.Wherein supporting mass rod baffle assembly 8 is embedded latticed rod baffle supporting mass, and it has fundamentally cancelled the version of former deflection plate, is to rabbet mutually with the lamellar formula rod baffle 15 of band embedding mouth groove 14 to form.The specification of rod baffle 15 should be determined according to the actual needs of assembly 8.Thick δ=the 3-10mm of the lath of rod baffle 15 generally speaking, the wide b=ω+5mm of lath is advisable, and ω is the corrugated tube pitch of waves.Specification shape as for lath embedding mouth groove 14 then should be determined according to the interlocking angle α of rod baffle assembly 8.When angle α=90 of rod baffle assembly 8 interlocking squarely grids ° (corrugated tube is the corner square arrangement), embedding mouth groove 14 groove width L1=δ+1mm; When angle α=60 of rod baffle assembly 8 interlocking diamondwise grids ° (corrugated tube is positive triangle arrangement), embedding mouth groove 14 groove width L2=2 δ, groove depth h=0.5b+1mm.Interval S between each embedding mouth groove 14 equals corrugated tube centre-to-centre spacing.All the other each parts adopt existing structure, and tube bank 5 is constant substantially.
During use,, determine the interlocking angle α of rod baffle assembly 8, select the lath thickness of rod baffle 15 then, process the embedding mouth groove 14 on the lath according to the arrangement requirement of bellows.According to its different bearing position, interlocking is integral formula square net or network shape supporting mass mutually with each rod baffle 15 of processing.Weld with the interlocking crosspoint of rod baffle assembly 8 and with the outer ring contact portion at last.Adopt a plurality of rod baffle assemblies 8 can use spacing bar 6 spacing.
The utility model is widely used, and can be used for the heat exchanger tube heat exchanger of various structures, and it is not only the desirable vibration proof structure of ripple tubing heat exchanger tube, and is the ideal supporting structure of heat exchanger tubes such as finned tube, thin-walled light pipe.
