The utility model is implemented by following technical solution:
Develop the board-like heat exchanger of a kind of expanded metals combined type, comprise heat-exchanging component, frame and securing member, by the frame and the securing member at two ends, the in a row multiple row heat-exchanging component of combination as required in the middle of seizing on both sides by the arms connects the hot and cold MEDIA FLOW formation complete machine of threading a pipe, and it is characterized in that:
Described heat-exchanging component is divided into two kinds of A sheet and B sheets, the alternate combination with the B sheet of A sheet during assembling;
Described heat-exchanging component, every heat exchange net and sealing gasket interlocking are integral by heat exchanger plates, wherein,
Described heat exchanger plates is a stiffener plate, and self four limit turnup constitutes embedding mouth groove, and four jiaos of heat exchanger plates are provided with through hole;
Described sealing gasket, periphery are embedded in the embedding mouth groove of heat exchanger plates;
Described heat exchange net, be the cross-laminated formation of rigid filaments grid, its periphery embeds in sealing gasket.
Above-mentioned heat exchange net, be the cross-laminated formation of rigid filaments rectangle or network; Or the cross-laminated formation of waveform rigid filaments rectangle or network;
Inner edge side setting＜shape caulking groove that above-mentioned sealing gasket, itself and heat exchange net are inlayed;
Above-mentioned sealing gasket,, be used for A sheet person, its upper left and lower-right diagonal position respectively has a seal channel, and heat exchanger plates through hole outer rim is hermetically sealed, and on the sealing gasket two sides overflow launder is set all;
Above-mentioned sealing gasket is used for B sheet person, and respectively there is a seal channel at its upper right and diagonal angle, lower-left, and heat exchanger plates through hole outer rim is hermetically sealed, and on the sealing gasket two sides overflow launder is set all;
Above-mentioned frame, its upper/lower terminal is provided with locating slot, and its and arranged on left and right sides is provided with fastener hole.
The utility model has the advantages that:
1. heat exchanger plates is a stiffener plate, without " damage " of machining, does not have machined to produce cancavo-convex " peak " and " paddy ", has thoroughly stopped " point " corrosion drawback;
2. the major part of heat exchanger plates is the dull and stereotyped state without machining, and the pressure of heat transferring medium, temperature and changes in flow rate in the operation process can not produce uneven stress deformation;
The heat exchange net be superimposed, be embedded between heat exchanger plates, this architectural feature allows heat exchange net that certain displacement is arranged, and can cushion the stress that variation produced of heat transferring medium pressure, temperature and flow, can not influence sealing property.

The specific embodiment
Among the figure, the 1st, right frame; The 2nd, securing member, a common side is reserved with enough spaces, and preparing against increases heat-exchanging component when needing; The 3rd, last backstay, the 4th, following backstay, 3 and 4 have fixed the position of heat exchanger plates and frame; The 5th, medium 1 passage; The 6th, medium 2 passages; The 7th, left frame; A and B are heat-exchanging components alternately; The 8th, trellis heat exchange net; The 9th, sealing gasket; The 10th, the hole, angle; The 11st, the crimping of heat exchanger plates constitutes the embedding mouth groove that holds sealing gasket; 121 and 122 is the overflow launders on the sealing gasket, is used for A sheet person, and its upper left and lower-right diagonal position respectively has a seal channel, and heat exchanger plates through hole outer rim is hermetically sealed; Be used for B sheet person, respectively there is a seal channel at its upper right and diagonal angle, lower-left, and heat exchanger plates through hole outer rim is hermetically sealed; At sealing gasket seal channel arranged outside overflow launder; 131 and 132 is the locating slots at heat exchanger plates two ends; The 14th, the section of heat exchanger plates crimping; The 15th, longitudinal metallic wire in the heat exchange net; The 16th, the cross section of portion transverse wire in the heat exchange net; The 17th, embedding mouth groove; 18, the 19th, the locating slot at frame two ends; The 24th, medium 1 import; The 20th, medium 1 outlet; The 21st, medium 2 imports; The 22nd, medium 2 outlets; The 23rd, the fastener hole of frame side; Fastening by securing member 2, the multiple row heat-exchanging component of combination as required in a row in the middle of seizing on both sides by the arms connects the hot and cold MEDIA FLOW formation complete machine of threading a pipe.
Because design feature of the present utility model, heat exchanger plates does not have machined to produce cancavo-convex " peak " and " paddy ", has thoroughly stopped " point " corrosion drawback; The pressure of heat transferring medium, temperature and changes in flow rate in the operation process can not produce uneven stress deformation, and processing technology is simplified; The heat exchange net be superimposed, be embedded between heat exchanger plates, can cushion the stress that variation produced of heat transferring medium pressure, temperature and flow, can not influence sealing property.Combination is flexibly adjusted easy to maintenancely, unclamps clamp nut and can carry out clean and maintenance, replacing sealing gasket, heat exchange net or heat exchanger plates.Heat-exchanging component is separate unit, can arbitrarily increase and decrease heat exchange area and flow process by customer requirements.Four angles of heat exchanger plates have the hole, angle and edge pastes sealing gasket, when equipment clamps, sealing gasket is tightly connected each heat exchanger plates by the path combination form, the hole, angle, place, diagonal angle of each row heat exchanger plates interconnects, form mazy medium channel, make heat transferring medium reverse flow in adjacent passage, carry out sufficient heat exchange through reinforcement heat radiation, thermal convection current, heat conduction.Because the special structure of heat exchanger components, strong turbulent flow just can be evoked in the assembling back under lower flow velocity, thereby has accelerated the destruction of fluid boundary layer, has strengthened diabatic process.
Through test, satisfactorily reach the goal of the invention of expection.The utility model is the ideal structure of the update of plate type heat exchanger.
