Description
Technical field
The invention belongs to heat exchanger, be specifically related to a kind of microcapillary bundle heat exchanger of nonmetallic materials.
Technical background
Along with the micromachine broad application, the heat dissipation problem of excessive heat current density becomes a difficult problem that needs to be resolved hurrily in the micromechanics so, and simultaneously according to the practical needs of energy-saving and emission-reduction, the heat transmission equipment of developing high-efficiency compact more is significant.In heat transmission equipment, metal tube shell-type heat exchanger still occupies sizable ratio at present.The defective of this conventional tube shell heat exchanger is, caliber is thicker relatively, and heat-exchanging tube bundle is longer, and temperature distributing disproportionation is even, and heat exchange efficiency is low.And according to statistics 60% above hardware scrap all relevant with corrosion.Then has good corrosion resistance so select corrosion resistant nonmetal (such as polytetrafluoroethylene (PTFE), perfluoroethylene-propylene) material to make heat exchanger.Because the microcapillary bundle heat exchanger has very high heat exchange area and volume ratio and superpower characteristics such as bearing capacity, is subjected to people's favor day by day." duct type microtubule heat exchanger " (ZL 200710057134.7); And " efficient heat-exchanging pipe " disclosed technology such as (ZL 200810143021.3) with minuteness passage; Its heat exchanger is formed by the interior pipe box dress of outer tube and not conducting, forms rule or the irregular micro-channel of hydraulic diameter less than 3mm between inner and outer pipes.But the manufacture craft of this heat exchanger tube is difficulty very, and material therefor is still metal tube." hig efficiency thin tube heat exchanger " is a kind of shell heat exchanger with efficient enhanced heat exchange characteristics (ZL2001131478.8), and the major technique feature is to have changed big caliber heat-exchanging tube bundle into thin-walled tubule footpath heat-exchanging tube bundle, still adopts metal material.The heat-transfer effect of metal material is better than the nonmetallic phase material really, but the metal material caliber is more little, tube wall is thin more, is difficult to processing more, the more important thing is that corrosion resistance is huge poor, and service life is short, manufacturing cost is quite high.
Summary of the invention
At above-mentioned technological deficiency, the purpose of this invention is to provide a kind of nonmetal fine tube bank and the tube bank interface is the heat exchanger of mode of being flexible coupling.
Followingly know-why of the present invention and apparatus structure are described with reference to accompanying drawing.The technical characterictic of nonmetal microcapillary bundle heat exchanger is that the cold fluid tube bank is passed total tube sheet with the hot fluid tube bank and fixed by total tube sheet and heat exchanger shell.The two ends of cold and hot fluid tube bank are connected and fixed with dividing tube sheet, divide tube sheet and tube sheet joint to fix, and heat exchanger shell is equipped with conductive fluid and replenishes interface.
The flexible pipe that described cold and hot fluid tube bank is made for nonmetallic materials.
The external diameter of described cold and hot fluid tube bank is 0.1mm-3.0mm; Pipe thickness is 0.005mm-0.5mm.
Described total tube sheet is a hexagon cellular shape with the arrangement mode that divides the tube sheet perforate; Or square; Or triangle.
Described nonmetallic materials are polytetrafluoroethylene (PTFE), or perfluoroethylene-propylene.
The material of described heat exchanger shell and tube sheet joint is a metal; Or glass fiber reinforced epoxy resin; Or phenolic resins, the material of total tube sheet, branch tube sheet is a polytetrafluoroethylene (PTFE); Or perfluoroethylene-propylene.
Described cold and hot fluid tube bank two ends and being connected of branch tube sheet be rise connect fixing; Or be adhesively fixed; Or be fixed into one with a minute tube sheet behind the tube bank global formation.
The appearance profile of described minute tube sheet is circular; Or square.
Characteristics of the present invention are: the fine tube bank of cold and hot fluid in heat exchanger shell and total tube sheet outside is the mode that is flexible coupling with dividing tube sheet, is being connected with system after promptly tube bank converges to branch tube sheet connector.Heat-exchanging tube bundle in heat exchanger shell along the axis direction storied placement, in the enclosed cavity that heat exchanger shell and (cold and hot fluid) fine tube bank outside are constituted, fill the intermediate thermal conductivity liquid of good heat conductivity simultaneously, replenishing with monitoring of conductive fluid is connected the special equipment operation by the additional interface of conductive fluid, to guarantee the normal operation of heat exchanger.The external diameter of microcapillary can be selected to determine according to the thermal physical property parameter or the flow of cold fluid and hot fluid.Certainly, the cold and hot fluid tube bank can be exchanged, and cold and hot fluid divides tube sheet also interchangeable.
The present invention compares with metallic recuperator has following characteristics:
(1) fine tube bank has very high heat exchange area and volume ratio, can exceed one even several magnitude than traditional heat exchangers; Adopt the minor diameter thin wall pipe, can remedy the low shortcoming of plastics heat conductivility, again can proof strength.
(2) superpower corrosion resistance can be used for the heat exchange needs under the various heavy corrosion conditions, such as bath solution, high-temperature high concentration acid ﹠ alkali liquid and organic solvent etc.
(3) fine tube bank joint is flexible, is not subjected to the restriction in space, and pliability is good, and is applicable to the condition that has or not phase-change heat transfer.
(4) solved the difficult problem of the complexity of metal species microcapillary bundle heat exchanger processing technology, the metallic conduit inner surface is coarse relatively simultaneously, causes fluid flow resistance in pipe relatively large.
(5) cheap, adopt every square metre of tubing amount that is consumed of minor diameter thin wall pipe very little.Adopt the tubing of overall diameter Φ 5.0 * 0.5mm, every square metre of heat exchange area only needs the 1.1-1.4kg plastics.
