Description
The present invention relates to a kind of plate heat exchanger, it has the last fire dam of a perforation and following fire dam and the circulation duct of a plurality of heat transmission mediums of separately being formed by the longitudinally extending dividing plate of monoblock between fire dam, the header of forming horizontal pipeline is being arranged in free end zone at it, each circulation duct is injected in this header, this moment, header externally seal, and have heat transmission medium become a mandarin house steward with go out to flow house steward.
Deutsche Bundespatent 3241842 has been announced a kind of plate heat exchanger of the type.In this heat exchanger, the junction that inflow pipe enters into horizontal pipeline is flat nozzle.The form that flat nozzle is injected into horizontal pipeline is that flat nozzle is aimed at axial direction together with their flow ports and is placed in the free end of heat exchanger side by side adjacently.
The shortcoming of this known heat exchanger is by the dividing plate of partial dismantling longitudinal extension, to have formed the header that constitutes horizontal pipeline on the free end of heat exchanger between the upper and lower fire dam of heat exchanger.This moment, the lateral partitions between two fire dams was cut into corresponding length, and by heat, pressure (adding layer of adhesive in case of necessity) terminal of two fire dams was closely interconnected.
Heat exchange medium passes through inflow pipe, enter into the horizontal pipeline that forms by form of describing and method by pressure, and in the inflow horizontal pipeline, and then flow to horizontal pipeline on the free end of heat exchanger plate of a relative end by the circulation duct that is split to form by vertical division board, go out to flow house steward what this accumulated heat transmission medium.When the horizontal pipeline pressure that contains heat transmission medium raises, can cause disadvantageous consequence, promptly in the area of diaphragm that is cut, when horizontal pipeline pressure raises, the end of otch is the place that produces fracture in theory, and because the pressure of heat exchange medium can cause separating the dividing plate of the circulation duct of heat exchanger plate continues in the axial direction to tear.Therefore the compression resistance of known heat exchanger plate is less.
German patent specification 3545278 has been announced another kind of plate heat exchanger, avoided this shortcoming by following method, all or partially open in the heat exchanger plate fire dam one in end that circulation duct exposes perpendicular to plate axle ground, and header makes these opening parts that slender hollow body is placed into fire dam.
By removing each segmentation of fire dam, make and under the situation that all or partially keeps the divider wall between each circulation duct, expose circulation duct with limitation, thereby avoided axial cutting that divider wall is harmful to.This compares with known plate heat exchanger is an advantage, but in further implementing, this heat exchanger plate also has other shortcoming, can not guarantee in slender hollow body that promptly heat transmission medium has best distribution.
German patent specification 2505015 has been announced the another kind of plate heat exchanger that is made of plastics.In this heat exchanger, the connector of a longitudinal extension is arranged, it has the extremity piece that extends of two tubuloses on the width of connector.This moment, the free end of tabular connector was placed in the notch of tubulose extremity piece, and carried out the fluid seal welding in this position and extremity piece.Except not solving the problem of extremity piece internal distribution heat transmission medium, also have another shortcoming, promptly the tubulose extremity piece is connected with the free end symmetry of tabular connector, makes the pipe parts of both sides protrude in board plane.When therefore not having the additional structure measure, this heat exchanger plate can not be used as floor heating plate or wall heating installation plate, because the tubulose of extremity piece protuberance partly protrudes in each board plane, has so just hindered this heating installation plate that one flat surface is arranged.
Task of the present invention provides a kind of plate heat exchanger, in this heat exchanger, the distribution of heat transmission medium in header compared with prior art is more perfect, and the arrangement of the header on the free end of heat exchanger plate does not hinder it to make the usefulness of floor heating plate or wall heating installation plate.The present invention suggestion: header is designed to have monolateral asymmetrical section, and from becoming a mandarin house steward or go out to flow the terminal of manifold area to them, the volume of header reduces gradually.
In the present invention, header is becoming a mandarin house steward or go out to flow the zone that house steward compiles maximum section is arranged.
Volume reduces to terminal gradually from the interior section zone of maximum.This means: when the header increased pressure among the present invention, heat transmission medium enters into its terminal from the volume area of header maximum, and enters each bar circulation duct of plate heat exchanger more equably from header.
Header among the present invention is made up of the die casting of monoblock, and the inflow pipe of heat transmission medium and outflow tube similarly are made up of single tube in this header.Die casting extends on the whole width of plate heat exchanger, and is enclosed within on the terminal of plate heat exchanger.In this case, die casting carries out the fluid seal welding with the surface that plate heat exchanger cooperates in the overlap joint zone.This moment, the heavy wall of the die casting of lap-joint almost can be put into the upper and lower fire dam of heat exchanger fully by pressure and heat, and the stream ü taro of this place's heat exchanger changes the large taro of Mei Ge and says that shining scratches the postscript shank
For guarantee die casting at its base position as the coffer of plate heat exchanger, the free end of die casting can be processed into the projection of peg shape, the cross section that these are protruding and the circulation duct of plate heat exchanger adapt, and when die casting installed on the free end of heat exchanger, these projectioies were halved together with the circulation duct that matches.In this way, except supporting die casting, when heat exchanger is multithread, also can correspondingly each runner be separated.
In the edge region, the projection of these peg shapes was used for die casting is fixed on the heat exchanger end before welding is carried out.Owing in this plate heat exchanger, a plurality of operational circulation ducts are arranged, when the one or more circulation duct of peg shape projection sealing, be not what be harmful to.
For the ease of being placed in the circulation duct, the projection of peg shape can be processed into taper.This peg is placed in the circulation duct of the edge of heat exchanger just more favourable, can strengthen the sealing in this zone thus.Peg constitutes this shape and helps die casting be fixed on the end of plate and die casting is fixing onboard before welding beginning.
In the multithread heat exchanger, for example double fluid must have such peg to be placed into middle flow pipeline in the heat transmission medium inflow region.Inlet and outlet with plate heat exchanger separates in this way.
In three stream heat exchanger plates, the peg that seals is put into first 1/3 place of plate between inlet and the outlet respectively with staggering.Obviously, in welding process, the peg in circulation duct welds at its root, and it is the fluid sealing that its welding will make its respective streams of putting into thread a pipe, and in the time of welding process, the die casting fluid is fixed on the end of plate hermetically.
The overlap joint zone can be selected arbitrarily between die casting and the plate end.Only require that overlap joint must have enough degree of depth, guarantee that carrying out fluid between plate end and the die casting is connected hermetically.
Experiment determines that best overlap joint value is 5mm to 8mm.Peg inserts in the circulation duct with same insertion depth, also can be supported.
When making heat exchanger of the present invention, make the free end of heat exchanger become in 90 ° of planes with the plate axle to extend, and will have the house steward that becomes a mandarin and become asymmetric shape with the Machining of Pick-up Tube that goes out to flow house steward, do proving useful like this.Die casting has asymmetrical shape like this, at inflow pipe or outflow tube zone maximum volume is arranged, and its volume reduces gradually to terminal.For the single current heat exchanger, this terminal just can be the terminal point of plate width, during opposite if multithread, is exactly zone line (double fluid) or first zone of 1/3 (three stream).
On the contrary, the asymmetric shape of the free end of heat exchanger ground extends, and the foundation design that has become a mandarin house steward and a header that goes out to flow house steward is in becoming 90 ° plane with the plate axle, and this also belongs to the scope of the invention.Can obtain one in this way outwards is straight coffer, and this benefits in some specific operating positions.
In the zone of the volume that forms by inflow pipe, by the necking part in the exterior wall of header heat transmission medium is turned to, this helps making heat exchange medium that distribution is preferably arranged in header.Adopt this measure, can make heat transmission medium volume flow autotelic turning in header.
Necking part in the header exterior wall can have a drift angle β, and it is relevant with the width of the flowing velocity of the direction of the inflow angle α of inflow pipe, heat transmission medium and horizontal pipeline.Experiment finds that inflow angle α can be between 0 ° to 180 °, and drift angle β should be between 0 ° to 90 °.When the heat transmission medium volume flow is that if inflow angle α is 90 °, the width of header was 200 millimeters (three flow structures) when flowing velocity was 13.8 cels in 100 liters/hour and the inflow pipe, drift angle β then is 21 °.Under same prerequisite, if when the width of header is 600 millimeters (single current structure), drift angle β then is 18 °.Under identical prerequisite, if inflow pipe α is 75 °, when the width of header was 200 millimeters (three flow structures), best drift angle β then was 26 °.Set out thus, when volume flow and flowing velocity reduced, drift angle β was always less in principle.
Go into head piece and go out head piece that to be placed on the outer terminal area of header be suitable.Yet in the scope of the invention, go into head piece and go out in the zone line of appointment that head piece also can be placed on header.Following schematic diagram has been represented the embodiment of heat exchanger of the present invention:
Fig. 1: expression be the straight cuts end that has the heat exchanger plate of the header that is shaped by the present invention,
Fig. 2: expression be the beveled end that has the heat exchanger plate of linearly extended header,
Fig. 3: similar with Fig. 2, expression be the multithread heat exchanger plate that has the total transfer of volume flow,
Fig. 4: be the partial section view of heat exchanger plate shown in Figure 3, go into the zone line that head piece is arranged in header,
Fig. 5: expression is from the various possible version of the heat exchanger plate of single current to three stream.
Fig. 1 represents to have the heat exchanger plate 1 of circulation duct 11 and the dividing plate 12 between each circulation duct 11.The free end 13 of heat exchanger plate 1 is by becoming 90 ° plane cutting to form with the plate axle.On the free end 13 of heat exchanger plate 1, be provided with the header 2 that has the house steward 21 that becomes a mandarin.Header 2 is die castings of non-symmetric figure, and it has maximum volume in the zone 22 of going into head piece 21, and maximum volume district 22 reduces gradually towards the minimum volume district 23 of the relative end of header simultaneously.Header 2 overlaps with the free end 13 of heat exchanger plate 1, and is sealed fixing at overlap 14 utilization welding carrying out fluid.
Fig. 1 has represented single current heat exchanger plate 1, and what it had header 2 and a heat transmission medium goes into head piece 21.Heat exchanger plate 1 is cut in the vertical, does not express the header 3 that has stream house steward 31 among the figure.
Fig. 2 represents to have the heat exchanger plate 1 of asymmetric free end 13, and the header 2 of bringing stream house steward 21 into is housed above it.
In Fig. 2, inflow pipe 21 inserts in the header 2 under the situation of inflow angle α=90 °.Fig. 2 has also represented single current heat exchanger plate 1, in this drawing, passes through the cross section showed, can not see the header that has stream house steward 31 3 over there.
Fig. 3 is partial cross section figure, and expression has the multithread heat exchanger plate of the total transfer of volume flow by the layout of Fig. 2.Header 2 is a die casting, and it is placed on the terminal area 13 of cutting sth. askew of heat exchanger plate 1.Dotted line is represented overlap 24.Header 2 overlaps with the corresponding abutment wall of heat exchanger plate 1 by its outside terminal area 25 that is positioned at, and is connected with it by welding.A taper peg 12 is embedded in and is arranged in outside circulation duct 11, and this peg almost extends on the whole width of overlap 24.When welding header 2 overlaps 24, similarly, taper peg 12 welds with the terminal area 13 of heat exchanger plate 1 by this way, peg fluid sealing circulation duct 11.
Fig. 3 has represented three stream heat exchanger plates 1, at first 1/3 place of this heat exchanger plate width, a corresponding fluid-tight device must be arranged, and reaches this airtight by peg 13.This peg 13 is identical with peg 12, puts in the circulation duct that is mated, and the fluid seal welding is also carried out in the there.In the maximum volume zone 22 of header 2, in the bottom of inflow pipe 21 heat transmission medium is turned to by wall necking part 26.In the drawings, to keep drift angle β=21 °, this drift angle be to become with respect to plate axle inflow angle α under 90 ° the situation to draw for wall necking part 26.
In this embodiment, the flowing velocity of heat transmission medium VA=13.8 cel in inflow pipe 21.
This moment, volume flow was 100 liters/hour, and in the structure of the pointed header that has heat exchanger plate 2, the flow velocity in the circulation duct of inflow heat exchanger plate is the Vp=2.2 cel.At this moment the flowing velocity in header 2 can not be greater than VA, can not be less than Vp.If the flowing velocity VS=VP=2.2 cel in the header 2, the inclination angle of heat exchanger plate 1 free end 13 or the inclination angle of header are 23 °.
When VS=2 * VP=4.4 cel, the inclination angle can not be greater than 11.5 °; When VS=3 * VP=6.6 cel, this angle be 7.5 ° suitable.When the 1/2VA+VP=8 cel, the drift angle of header is 6 ° at last.This embodiment is an optimum state, because this moment, the flowing velocity in header was the mean value of VA and VP.
Clearly explanation thus reaches best flowing when making heat transmission medium by heat exchanger plate 1, and inflow angle α and necking part 26 drift angle β are also relevant with the width of the flowing velocity of volume flow, heat transmission medium and header 2.Above calculating be that width at three stream heat exchanger plates and headers are to draw under the situation of 200mm.
Fig. 3 clearly shows basic characteristics of the present invention, as the header 2 of volume flow transfer 26 and taper trend.If there are not these characteristics, the heat transmission medium of inflow just directly is distributed in each circulation duct 11 of heat exchanger plate, remains in the volume flow in the straight header, will reduce the amount of its reduction for being received by every circulation duct 11 respectively.If header 2 is a uniform section, the flowing velocity of heat transmission medium will begin to reduce from inflow pipe 21, therefore cause heat transmission medium to flow into each circulation duct of heat exchanger plate unevenly, will in heat exchanger plate, cause a kind of undesirable uneven heat distribution like this.
Because the spatial form of transfer 26 of the present invention and header 2 can satisfy actual requirement, so can make heat transmission medium reach even flowing velocity in heat exchanger plate.
Last Fig. 4 represents the connection of inflow pipe 21 on the centre position of header 2.In this case, turning to of heat exchange medium volume flow must be carried out on two directions.For this purpose, in header 2, directly, replace single transfer and a twin-steer 26 is set in the inside of header 2 in the going into below the head piece of inflow pipe 21.Structure among Fig. 4 has the whole advantages in Fig. 3 structure.
