Description
Technical field
The present invention relates to a kind of heat exchangers, more particularly, to a kind of fin plate heat exchanger.
Background technology
The application range of heat exchanger is very extensive, and structure type is various, since industrial civilization has been invented with the mankind
With the heat exchanger for having used tens kinds of structures, typical structure such as shell-and-tube, bushing type, board-like（Point detachably with it is non-dismountable）
And spiral plate type, plate-fin（Corrugated tube type, parallel flow type, stacked and radiator corrugated tube type including air conditioning for automobiles）, pipe
Chip etc..In certain particular applications for requiring compact efficient, space limitation, weight to limit, while also requirement can be safeguarded
In the case of property, service life and reliability, the heat exchanger of the above structure all has its limitation.
Plate heat exchanger disassembling cleaning is convenient, efficient, light weight and cost is low, combination is convenient, and logarithmic mean temperature difference (LMTD) is big,
Heat transfer temperature is efficient, but baffle surface does not have expanding area, the compactness of heat exchanger（Or area density）β value generally only has
120~1660 m2/m3。
Plate-fin heat exchanger brazing fin on partition board, heat transfer area are partition board area and fin expanding area（Virtual value）
The sum of, general compactness β is easily up to 1700~2600m2/m3More than, the equivalent diameter of heat exchanger only has 1.8~3.5mm left
The right side, general 30% or more the plate heat exchanger raising of ratio of heat transfer coefficient, efficient, compact, small and light-weight, saving space and material
Material.
General plate-type heat exchanger slab forming technique difficulty it is big, can not one-pass molding, technique is cumbersome, product qualified rate
It is low, about only 73%~84%, the production cost is very high.
Invention content
The present invention provides a kind of fin plate heat exchanger, it is described that its technical solution is as follows：
A kind of fin plate heat exchanger includes the side plate of both sides, and the partition board that setting is stacked between the side plates, is arranged on side plate
There are the inlet and outlet connectors of cold fluid and hot fluid, there are four inlet and outlet connectors, respectively hot side entrance, hot side outlet, cold side input port, cold
Side outlet；The partition board is provided with corner apertures corresponding with inlet and outlet connectors；The partition board both sides are provided with the wing of Welding
The fin of piece, side flows cold fluid by corner apertures, and the fin of the other side flows hot fluid by corner apertures；Partition board periphery is provided with
Sealed groove structure is provided with sealing strip in sealed groove structure.
The corner apertures of the partition board setting includes hot side entrance corner apertures corresponding with hot side entrance and the corresponding heat of hot side outlet
Side outlet corner apertures, the corresponding cold side input port corner apertures of cold side input port, the corresponding cold side outlet port corner apertures of cold side outlet port.
The fin of the partition board both sides, the fin of side access hot fluid by hot side entrance corner apertures, and from hot side outlet
Hot fluid is discharged in corner apertures；The fin of the other side accesses hot fluid by cold side input port corner apertures, and heat is discharged from cold side outlet port corner apertures
Fluid.
The fin includes distributing fin, heat exchange fin, and the distributing fin is located at heat exchange fin both sides, is connected with corner apertures
It connects, the heat exchange fin is located among distributing fin, is used for transmission fluid.
The fin of the partition board both sides, the flow direction for flowing cold fluid and hot fluid are opposite.
The baffle combination part that the partition board and the fin of both sides are constituted as heat exchange element, block board thickness 0.6~
2.0mm, 0.12~0.3mm of fin material thickness is stamping, 2.0~6.0mm of fin height, and partition board and fin pass through vacuum pricker
Weldering is bound up.
The side plate of both sides is fixed by stud, nut.
Fluid on side plate forms shunting or bus structure by the distributing fin being connected with corner apertures.
The present invention is only molded plate slot sealed around and corner apertures, enormously simplifies original plate heat exchanger complicated shape plate
The runner moulding process of piece considerably reduces technology difficulty and press tonnage, and molding qualification rate is almost up to 100%, substantially
Degree reduces cost.
The present invention has concentrated the advantages of plate heat exchanger and plate-fin heat exchanger：Efficiently, compact, light-weight, small, can
It dismantles, is at low cost.It solves the problems, such as that plate heat exchanger coefficient of heat transfer when there is gas converting heat is low, solves plate-fin heat exchanger
Anticorrosion when exchanging heat in face of corrosive fluid medium and detachable maintenance issues.
For plate-fin heat exchanger, especially when naval vessel seawater is cooling or other corrosive gas heat exchange, when every
It is advance using titanium alloy fin and partition board if prohibitively expensive using soldering plate-fin heat exchanger cost when plate material is titanium alloy
The material cost of product will be greatly reduced in heat exchanger made of fin plate component stacked combination made of brazing sheet, avoid by
Because soldering seam leakage makes the quality cost that core is scrapped after the soldering of titanium alloy core.Plate-fin heat exchanger end enclosure structure is difficult to simultaneous
The water conservancy diversion problem of fluid inlet and outlet is cared for, plate heat exchanger then passes through the direct stamping split channel on plate（Busway）
And water conservancy diversion runner preferably solves.This advantage of fin plate heat exchanger absorption plate heat exchanger, directly setting shunting（Or it converges
Stream）Fin and distributing fin soldering form shunting on partition board（Confluence）Channel and flow-guiding channel, shunting（Confluence）Fin, water conservancy diversion
Fin so that flow field is more uniform, and easily the weak region of fluid flow is adjusted after being analyzed using fluid emulation software
It is whole, optimize heat exchanger interior flow field, and shunt（Confluence）Section and diversion section have been in strong heat convection state, ingenious
Ground solves shunting（Confluence）, water conservancy diversion, flow field uniformity, flow resistance matching, heat transfer and support the problem of.
Further, heat exchanger surrounding uses rubber weather strip structure, and fin plate surrounding design sealing channel structure can be
2.5MPa（Gauge pressure）With 200 DEG C at work normally, the restriction maximum operating temperature for being limited by rubber packing material is generally difficult super
250 DEG C are crossed, the level of resistance to mild pressure resistance is identical as general plate heat exchanger, and heatproof, pressure resistance and sealing performance are not so good as plate-fin
Heat exchanger.
