Abstract
The invention discloses a heat exchange plate sheet of a welded plate type heat exchanger. The plate sheet is realized through inwards bending one corresponding side of a corrugated plate sheet, outwards bending the other corresponding side of the corrugated plate sheet, enabling the two sides of the corrugated plate sheet to form two corresponding straight surfaces or angular surfaces and arranging vanes at lengthened parts of the two adjacent bent straight surfaces or angular surfaces of the corrugated plate sheet. The welded plate type heat exchanger formed by the plate sheet has the characteristics of small fluid resistance, good heat transfer performance, energy conservation, steadiness in operation, and the like, can bear higher temperature and pressure, and has the advantages of compactness and reasonability in structure, strong technological adaptability, convenience in maintenance and cleaning, reliability in working performance, long service life, and the like.
Description
Technical field: the present invention relates to a kind of heat exchanger plate, relate to the heat exchange plate in a kind of welded plate type heat exchanger specifically.
Background technology: plate type heat exchanger is a kind of efficient and compact heat transmission equipment; Have that heat transfer efficiency height, drag losses are little, maintenance and plurality of advantages such as easy to maintenance; And along with the improvement of structure and the raising of manufacturing technology, the application of plate type heat exchanger receives people's attention day by day.But traditional plate type heat exchanger adopts plate as heat transfer element, is made up by certain way by a lot of plates, adopts rubber gasket to seal between each plate, thereby forms cold and hot two kinds of fluids (medium) passage.Owing to rubber gasket at high temperature easy ageing lose sealing function medium when being used for special media rubber sheet gasketing had corrosivity, therefore traditional plate type heat exchanger can not bear higher temperature and pressure and not be suitable for the occasion that gasket seal is had corrosion.In the case, welded plate type heat exchanger has been invented in this field.Welded plate type heat exchanger also be with heat exchange plate as heat transfer element, connecting between plate and between plate and main frame is to realize through welding manner, and forms cold and hot two kinds of fluid passages thus.Owing to be to adopt Welding Structure but not rubber sealing structure, therefore under the operating mode of higher temperature and special media, remarkable advantages has been arranged than plate type heat exchanger.Yet because the limitation of original welded plate type heat exchanger structure; Though can overcome said traditional plate type heat exchanger defective, structurally still exist thermal (temperature difference) stress can't effectively eliminate and cause can not be used for the defective that higher temperature and Welding Structure can not be born elevated pressures.
Summary of the invention: the invention reside in the heat exchange plate that a kind of welded plate type heat exchanger is provided; Purpose is to solve traditional plate type heat exchanger can not bear higher temperature and pressure, can not satisfy the heat exchange demand of some special medium and the problem that common welded plate type heat exchanger can not bear higher temperature and elevated pressures.
The present invention is realized by following technical scheme: it comprises corrugated cardboard sheet; Mainly be through with crooked in the corrugated cardboard sheet one corresponding side direction; Another respective side is outwardly-bent, makes it form two corresponding facing directly or the inclined-plane, and faces directly or the extension site, inclined-plane is provided with the Ji sheet in two of adjacent flex.
Heat exchange plate of the present invention compared with prior art has following particular performances characteristics:
1, because plate of the present invention is arranged in the corresponding side direction crooked; Another respective side is outwardly-bent, and faces directly or the extension site, inclined-plane is provided with the structure of Ji sheet in two of corrugated cardboard sheet adjacent flex, and the welding of plate and plate is butt weld when forming product; Effectively improved the bearing capacity of product; Because the existence of Ji sheet makes the welded plate type heat exchanger product that adopts this plate to form have the ability of effective elimination thermal (temperature difference) stress, therefore be applicable to higher serviceability temperature simultaneously.
2, because this heat exchanger plates need not be installed gasket seal between plate, avoided that rubber gasket is at high temperature aging to lose the disadvantage of sealing function with special media to the corrosion of rubber sheet gasketing, significantly widened the scope of application of plate type heat exchanger.
3,, increased effective heat exchange area, significantly reduced fluid resistance because the acerous hole of the traditional relatively heat exchange plate of this heat exchange plate.
4, owing to taked particular structure, make the welding of plate can adopt more high performance welding method such as laser weld, increased welding reliability, significantly reduced welding heat affected zone, improved the stability of operation, prolonged the service life of equipment.The heat exchanger that is made up of this invention can be more widely used in the processes such as heating, cooling, condensation, evaporation and recuperation of heat of numerous areas such as chemical industry, oil, power, metallurgy.
5, with the exception of this, novel uniqueness of inventive concept of the present invention, structural design compact and reasonable, stable and reliable working performance, suitablely promote in the industry.
Description of drawings:
Fig. 1 is a heat exchange plate structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of Fig. 1;
The plate bundle structural representation that Fig. 3 is made up of plate of the present invention;
Fig. 4 is the partial enlarged drawing of Fig. 3;
The specific embodiment:, be a kind of heat exchange plate of brand new by the heat exchange plate of the welded plate type heat exchanger of Fig. 1-shown in Figure 2.It is by crooked in the 1 one corresponding side direction of the corrugated cardboard sheet with definite shape; Another respective side is outwardly-bent; Make it form two corresponding facing directly or inclined-plane 2,3, and face directly or 2,3 extension sites, inclined-plane are provided with that Ji sheet 4 constitutes in two of corrugated cardboard sheet 1 adjacent flex.And the plate bundle structure of forming by plate of the present invention of Fig. 3-shown in Figure 4; Be with plate 1 of the present invention concretely; With its adjacent two plates, 1 mutual half-twist or overturn 180 °; The two adjacent plate edges part correspondence that matches is welded and formed plate bundle (heat transfer element), and the intrafascicular plate of plate forms two kinds of fluid passages at interval.And through the Ji sheet 4 is equipped with the fixing heat exchanger main body that forms of plate bundle and framework welding again side plate, adapter, flange and coupling bolt etc. and forms the welded plate type heat exchanger product.During work, cold fluid and hot fluid flows through in the passage of same plate both sides respectively, high temperature fluid through plate of the present invention with the heat transferred cryogen, thereby realize the purpose of heat exchange.
