Abstract

A heat interchanger with discontinuous asymmetric corrugated tube is broadly applied in modern commercial process, comprising a housing body with tube plates, a bundle of discontinuous asymmetric corrugated tubes, a tube box with end enclosures, and two flow passages composed of an inlet and an outlet of two mediums inside and outside the tube respectively for heat convection between the two mediums. The corrugations of the discontinuous asymmetric corrugated tube distribute on the wall of the tube in an oblique state. The corrugation trends of adjacent tubes are in opposite directions when a plurality of discontinuous asymmetric corrugated tubes make up of a bundle. The discontinuous asymmetric corrugations can enlarge the confusion area of crosscurrent medium outside the tube, enhance the medium flow interference and increase the turbulent level, thereby overcoming the shortcomings of the conventional symmetric corrugation simple interference with the fluid flow, the single direction of the fluid flow and a short flow path. The heating coefficients inside and outside the tube tend to achieve magnitude matching, and finally the gross heat transfer coefficient is raised. Meanwhile, the axial direction of this waveform is high in rigidity and vibration resistance and bound to have widespread social consequences.

Description

A kind of discontinuous asymmetric ripple heat exchange of heat pipe
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of discontinuous asymmetric ripple heat exchange of heat pipe.
Technical background
Heat exchanger is the capital equipment of heat exchange, has in fields such as central heating, petrochemical industry, oil product conveying, metallurgy, light industry, hotel and hospitals widely to use.In the suitability for industrialized production now, the most frequently used heat transmission equipment is late 1990s, the corrugated tube heat exchanger that current research develops.Described corrugated tube heat exchanger is a kind of novel, augmentation of heat transfer, high-efficiency heat exchanger equipment.Wherein, the employing bellows has replaced the heat exchange element-light pipe in traditional tubular heat exchanger, makes fluid in the inside and outside formation of pipe turbulent flow, thereby has improved the heat transfer coefficient inside and outside the pipe greatly.Existing corrugated tube heat exchanger, as Fig. 1, shown in 2, described corrugated tube heat exchanger comprises bobbin carriage 1, tube bank 2, housing 3, tube sheet 4, pipe import 9, shell import 10, pipe outlet 11, shell outlet 12, end socket 13 and flange 14, described bobbin carriage 1 is located at the two ends of housing 3, be connected with housing 3 by flange 14, there are end socket 13 sealings at bobbin carriage 1 two, described tube sheet 4 is two, be located at respectively between two bobbin carriages 1, described tube bank 2 is installed between two tube sheets 4, tube sheet 4 is provided with the hole that bellows 5 is installed, and communicate with bobbin carriage 1, form the pipe inner flow passage, outermost layer is that housing 3 is tightly connected by flange 14 and bobbin carriage 1, form the pipe outer flow passage, the entire equipment two ends are respectively equipped with pipe import 9, shell import 10 and pipe outlet 11, shell outlet 12, as shown in Figure 3, described tube bank 2 is arranged in parallel by some bellowss 5 and forms, a bellows 5 drawn among the figure as schematic diagram, and all the other bellows 5 usefulness chain-dotted lines represent, as shown in Figure 4, bellows 5 tube walls manufacture discontinuous ripple state, be that tube wall the preceding paragraph has ripple, one section non-ripple, and fixing with tube sheet 4 welding.A kind of medium is entered in the tube bank 2 through bobbin carriage 1 by pipe import 9, and the bobbin carriage 1 that arrives another headband end socket 13 then flows out from pipe outlet 11 again, forms the pipe inner flow passage; Another medium is then flowed out from the shell outlet 12 of the other end through housing 3 by shell import 10 again, form the pipe outer flow passage, because bellows 5 tube walls manufacture ripple one by one, when so medium flows in pipe, its laminar flow layer is destroyed by scraggly wall, has so just improved the turbosphere of medium greatly, forms continuous spiral vortex type turbulent flow, can reach heat exchange effect more fully, thereby improve the convective heat-transfer coefficient between medium.But the ripple on the heat exchange bellows of this class heat exchanger is symmetry status, be ripple its up and down crest and the trough symmetrical parallel on bellows 5 tube walls, the trend of ripple with the pipe outer MEDIA FLOW to parallel, and adjacent bellows 5 is lined up according to the mode of ripple symmetrical parallel, this shape is little to managing outer crossing current confusion area, so can not obtain inside and outside the pipe all turbulent flow fully simultaneously, the inside and outside heat transfer coefficient of pipe can not improve simultaneously, managing outer heat transfer coefficient does not match on magnitude with the interior heat transfer coefficient of pipe, restricted the raising of overall heat-transfer coefficient, the rigidity of symmetrical ripple is on the low side simultaneously, and vibration resistance is poor, and is not high to swiftly flowing medium heat transfer efficiency.
The utility model content

The technical solution of the utility model is achieved in that a kind of discontinuous asymmetric ripple heat exchange of heat pipe, comprise bobbin carriage 1, tube bank 2, housing 3, tube sheet 4, end socket 13 and flange 14, described bobbin carriage 1 is located at the two ends of housing 3, be connected with housing 3 by flange 14, there are end socket 13 sealings at bobbin carriage 1 two, described tube sheet 4 is two and is located between two bobbin carriages 1, described tube bank 2 is installed between two tube sheets 4, tube sheet 4 is provided with the hole that bellows 5 is installed, and communicate with bobbin carriage 1, form the pipe inner flow passage, outermost layer is that housing 3 is tightly connected by flange 14 and bobbin carriage 1, forms the pipe outer flow passage, and the entire equipment two ends are respectively equipped with pipe import 9, shell import 10 and pipe outlet 11, shell outlet 12, described tube bank 2 is arranged in parallel by some bellowss 5 and forms, and it is characterized in that: described bellows 5 is discontinuous asymmetric ripple pipe 6.
The ripple of described discontinuous asymmetric ripple pipe 6 is inclined to be distributed on the tube wall.
Described discontinuous asymmetric ripple pipe 6 is reciprocal relatively principle according to ripple incline direction on the adjacent tubes and is arranged in parallel and forms tube bank 2.
Characteristics of the present utility model are discontinuous asymmetric ripple pipe 6, pipe inner flow passage cross section is constantly changed, intraductal turbulance is more abundant, managing outer confusion area increases, add that adjacent corrugations is parallel asymmetric, make the outer turbulent flow of pipe more abundant, heat transfer coefficient has been realized the inside and outside coupling of heat transfer coefficient on the magnitude level of pipe than existing corrugated tube heat exchanger height, improved overall heat-transfer coefficient, and single ripple symmetry rigidity of discontinuous asymmetric ripple is little, and overall axial rigidity is big, helps antiscale and vibrationproof, asymmetric ripple pipe is during as vertical heat exchanger, ripple has the inclination angle, helps the whereabouts of steam condensate (SC), can improve vapour-heat transfer water coefficient.
