The specific embodiment
Concrete technical scheme of the present invention is: it strikes out inside and outside two layer heights and variform ripple on flat board, and peripheral ripple has the higher wave height and the bigger pitch of waves.The also double supporting role of doing between plate of fin of peripheral ripple.The wave height of internal layer ripple is less, mainly plays flow-disturbing and improves conductivity of heat.
On a flat board, strike out the composite corrugated plane of many rectangles that matrix arranges as shown in Figure 1; Described composite corrugatedly form by inside and outside two layers of ripple 2,3.The waveform of outer single ripple 2 as shown in Figure 2.Ripple 2 is arranged in pairs, and the longitudinal axis of two pairs of ripples 2 constitutes a rectangle.Transversely arranged ripple projection in the rectangle, vertical ripple is recessed, otherwise or.Outer ripple 2 has the bigger pitch of waves and higher wave height.Thereby can form big channel cross-section, the passing through of favourable liquid than thickness.The distance of rectangle opposite side is called the pitch of waves.The scope of the pitch of waves L1 of outer ripple: 30mm-80mm, the scope of wave height H is between 3mm-10mm, and the axial length of ripple is slightly smaller than the pitch of waves.
Be provided with ripplet 3 in outer ripple 2 inboards, its pattern has three kinds: the one, and the ripple of the similar outer ripple rectangular arranged of shape, shown in figure-3, the scope of pitch of waves L2 is at 10mm-50mm, and the scope of wave height h is between 1mm-6mm.The 2nd, many parallel ripples are set, as shown in Figure 4.The 3rd, a hemispherical dimples is set, shown in figure-5.The effect of internal layer ripple 3 has two: one, increases the rigidity of corrugated plating; The 2nd, increase the flow-disturbing of fluid at corrugated cardboard sheet, improve heat transfer coefficient.
Above-mentioned three kinds of composite corrugated cutaway views such as Fig. 6 are to shown in Figure 8.
2 one-tenth rectangular arranged of outside ripple on the plate of the present invention.Transversely arranged ripple projection in the rectangle, vertical ripple is recessed.Plate pipe of two plate 1 reverse superimposed compositions, a plurality of plate pipes constitute the plate bundle of a plate type heat exchanger.The ripple 2 of outer rectangular arranged is because the concavo-convex layout of ripple, thereby forms the passage of both direction in length and breadth.
The action and function of inside and outside two-layer different ripples 3,2 is different.The acting body of outer big ripple forms bigger runner now.Cross one another two wing passages of the fashionable formation of the plate groups that groove or fin are adjacent.The size decision fluid resistance of passage reduces, thereby can allow to pass through than the liquid of thickness.It is the reverse superimposed back formation supporting-point of two plates that the effect of fin has two: one; The 2nd, to the runner formation metering function of this side.Ripplet and hemispherical groove that ripple in the big ripple in the outside has rectangular arranged, bar shaped to arrange, its effect are to promote that fluid produces second-disturbing flow at corrugated plating, destroy fluid boundary layer, strengthen the coupling in velocity field and temperature field.Efficient hardening conducts heat, and realizes efficient heat transfer.Ripple also works to strengthen rigidity simultaneously.The size of the height of the tongue and groove of size, spacing and the ripple of outside ripple and the shape of interior ripple, wave groove all can be according to the physical parameter of heat transfer medium, and conditions such as allowable pressure drop are determined.Be combined to form the different runner of sectional area by corrugated plating.
During work, it is corresponding oppositely superimposed and form a plate pipe along the dual-side welding that two corrugated platings are pressed ripple.A plurality of plate pipes superpose and the vertical passage of formation plate pipe and the interconnection of plate pipe are welded in the port one side merging of adjacent two plate pipes.Two kinds of heat transferring mediums form two kinds of fluid cross flow one respectively by runner between plate pipe runner and plate, finish the diabatic process of two kinds of fluids.
Complex wave card bundle production example: the plate that profile is identical, it is corresponding to press ripple, forward and reverse basic heat transfer element that is superimposed together and continuous welding formation in both sides is called the plate pipe.A plurality of plate pipes are built up a plate bundle, at the two ends of plate bundle adjacent sheet film pack side weld are connect, thereby form plate pipe wing passage.Then the plate bundle is placed in the airtight housing.A kind of fluid is by plate pipe internal channel, and one other fluid is by the passage between the plate pipe.The fluid of different conditions passes through runner separately, and heat is passed to cryogen by high temperature fluid, and two kinds of fluids form cross-currents and finish the partition heat exchange.
