According to the all-welded energy-saving heat exchanger plate sheets, the two welding seams are formed through argon arc welding and seam welding, so that the pressure bearing capacity is greatly increased; and the two plate sheets cannot be separated when bearing the pressure, so that the plate sheets can be prevented being cracked, thereby avoiding waste of energy resource caused by medium leakage.
Description
Technical field
The utility model relates to a kind of heat exchanger plate, relates in particular to a kind of all welded type energy-saving heat exchanger plate.
Background technology
The application of plate type heat exchanger in industry has long history, and dominate in all heat exchangers still so far.Plate type heat exchanger is corrugated sheet to be arranged by certain intervals by many punching presses; And form with framework and overlapping the compressing of fishbolt; The runner interruption-forming of plate the distributing pipe and the manifold trunk of fluid; Reasonably cold fluid and hot fluid is separated again simultaneously, it is flowed in the runner of every plate both sides respectively, carry out heat exchange through plate.Plate type heat exchanger has following characteristics: 1) heat transfer coefficient is high: because different corrugated platings is inverted each other; Constitute complicated runner; Make fluid between corrugated plating, be the rotation Three-dimensional Flow in the runner; Can produce turbulent flow down at lower Reynolds number (general Re=50～200), so heat transfer coefficient is high, be commonly considered as shell-and-tube 3～5 times.2) logarithmic mean temperature difference (LMTD) is big; Terminal temperature difference is little: mostly plate type heat exchanger is and stream or counter-current flow mode; In addition, cold and hot fluid mobile in plate type heat exchanger is parallel to heat-transfer surface, no by-pass flow, therefore makes that the terminal temperature difference of plate type heat exchanger is little; Can be lower than 1 ℃ to the water heat exchange, and shell-and-tube heat exchanger is generally 5 ℃.3) floor space platelet formula heat exchanger structure is compact; Heat exchange area in the unit volume is 2～5 times of shell-and-tube; Also will reserve the maintenance place of extracting tube bank out unlike the shell-and-tube that kind, therefore realize same heat, the plate type heat exchanger floor space is about 1/5～1/8 of shell-and-tube heat exchanger.4) in light weight: the sheet of plate type heat exchanger is merely 0.5～1.5mm; And the thickness of the heat exchanger tube of shell-and-tube heat exchanger is 2.0～2.5mm; The housing of shell-and-tube is more than the framework recuperation of plate type heat exchanger, and plate type heat exchanger generally has only about 1/5 of shell-and-tube weight.5) price is low: adopt same material, under identical heat exchange area, the plate type heat exchanger price hangs down 40%～60% approximately than shell-and-tube.6) easy to make: the heat transfer plate of plate type heat exchanger is to adopt punch process, and standardization level is high, but and mass production, the general employing of shell-and-tube heat exchanger made by hand.
But the plate type heat exchanger operating pressure generally should not surpass 2.5MPa, and medium temperature should be lower than below 250 ℃, otherwise might reveal.Welding between two plates is the weakest part of pressure-bearing, and as shown in Figure 1, the first adjacent plate 1 and the both sides of second plate 2 are fixedly linked through argon arc welding.Pressure gets into plate is separated toward both sides, causes medium to reveal easily, wastes energy.In addition, first weld seam 3 that argon arc welding forms is more crisp, when big or weld seam is not so good when pressure even can cause cracking.Therefore, be necessary existing plate welding manner is improved, all welded type energy-saving heat exchanger plate is provided.
The utility model content
The utility model technical problem to be solved provides a kind of all welded type energy-saving heat exchanger plate, and is simple in structure, can prevent the plate cracking, effectively avoids medium to reveal wasting energy of causing.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of all welded type energy-saving heat exchanger plate; Comprise first plate and second plate; The both sides of said first plate and second plate are fixedly linked through argon arc welding; Wherein, the both sides of said first plate and second plate also fix on together through the seam solid welding, and second weld seam that the seam weldering forms is positioned at the inboard of first weld seam of argon arc welding formation.
Above-mentioned all welded type energy-saving heat exchanger plate, wherein, said first plate and second plate are formed by stainless steel, copper coin, titanium plate or the punching out of nickel plate, are formed with the corrugated channel that the cooling hot fluid passes through on said first plate and second plate.
Above-mentioned all welded type energy-saving heat exchanger plate, wherein, the thickness of said first plate and second plate is 0.5～1.5mm, the height of said corrugated channel is 2～15mm.
Above-mentioned all welded type energy-saving heat exchanger plate, wherein, the width of said second weld seam is 5～10mm.
The utility model contrast prior art has following beneficial effect: all welded type energy-saving heat exchanger plate that the utility model provides; Weldering forms the twice weld seam with seam through argon arc welding; Bearing capacity improves greatly; When pressure gets into plate, just can't make two plates separately, thereby can prevent the plate cracking, effectively avoid medium to reveal wasting energy of causing.
