Be used to implement pattern of the present invention
The embodiments of the invention that have further exploitation that describe below should be considered to just as example, and the protection domain that is provided by Patent right requirement is provided by no means.
Fig. 1 has shown the heat exchanger of a kind of plate and shell-type.Such heat exchanger is suitable for great majority to be used, and for example Chang Gui cooling and heating tasks, condensation, evaporation, seethes with excitement and Steam Heating again.It is particularly suitable for handling the application with high temperature and/or high pressure.Shown heat exchanger is circular, and it has circular housing and two fixedly connected end plates.
Fig. 2 has schematically shown the plate side stream passages of first embodiment that is used for heat exchanger.Such circulation road can be called as U type stream pattern.Fluid enters heat exchanger by ingress port 2 and flows through inlet stream pipeline 32.Fluid passes the folded group 17 of heat exchanger plate from inlet stream pipeline 32 and distributes, and heat exchange takes place in the folded group of heat exchanger plate 17 theres.Because it is much lower that the ducted pressure drop ratio of inlet stream passes the pressure drop of the folded group of heat exchanger plate, so fluid is distributed on the heat-transfer area of heat exchanger in basic mode uniformly.Fluid leaves heat exchanger by outlet stream pipeline 33 and outlet port 3.Circulation flow path utilizes arrow to show in the figure.Heat exchanger also comprises the folded group 21 of compensating plate that is positioned between first end plate 6 and the folded group 17 of heat exchanger plate.Compensating plate will be described below.
Fig. 3 has schematically shown the plate side stream passages of second embodiment that is used for heat exchanger, and wherein ingress port 2 is positioned in first end plate 6, and outlet port 3 is positioned in second end plate 7.Such circulation road can be called as Z type stream pattern.Fluid enters heat exchanger by ingress port 2 and flows through inlet stream pipeline 32.Fluid passes the folded group 17 of heat exchanger plate from the stream pipeline 32 that enters the mouth and distributes, and heat exchange is folded group 17 theres to take place with top described identical mode at heat exchanger plate.Fluid leaves heat exchanger by outlet stream pipeline 33 and outlet port 3.Circulation flow path utilizes arrow to show in the figure.In this embodiment, the folded group 21 of compensating plate is positioned between first end plate 6 and the folded group 17 of heat exchanger plate, and the folded group 21 of another compensating plate is positioned between second end plate 7 and the folded group 17 of heat exchanger plate.Depend on the size of heat exchanger and the quantity of employed compensating plate, may only use the folded group of a compensating plate just enough in this embodiment.
Shown in each embodiment in, ingress port 2 is provided with along inlet axis 34, and outlet port 3 is provided with along outlet axis 35.Inlet axis 34 and export axis 35 is arranged on central axis 36 with symmetrical manner relative both sides.
Heat exchanger comprises many corrugated heat exchanger plates 10,11, and it has the wavy pattern that comprises convex ridge 12 and groove 13.Convex ridge and groove have increased the heat-transfer area of heat exchanger, and produce the suitable pressure drop of passing circulation road.The purposes that depends on heat exchanger, this pattern can have different shapes.Heat exchanger plate is folded each other by this way to be organized together, thereby produces circulation road between plate, and this circulation road is called as plate side stream passages or first-class passage.First-class passage 14 produces between two adjacent plates 10,11.In this case, two plates are welded on the neighboring 9 of heat exchanger plate, thereby form heat exchanger plate box (cassette).Thereby having produced the volume of sealing, it is the part of plate side stream passages.The plate box is welded to one another together at port holes 16 places of heat exchanger plate.Like this, produced second circulation road 15 on the shell-side between the plate box, it is also referred to as the shell-side circulation road.The quantity and the size that are included in the plate box in the heat exchanger are selected according to the heating/cooling capacity of needed heat exchanger.The heat exchanger plate of welding constitutes heat exchanger core.Such heat exchanger core is well known in the art, and does not further describe.Circulation road in the heat exchanger can dispose according to different modes known to the skilled.
In known heat exchanger, ingress port pipe and outlet port tube are welded direct on the heat exchanger plate group, that is, be welded on the heat exchanger plate of the most close ingress port and outlet port, thus the plate side stream passages of acquisition pressure-tight.Ingress port pipe and outlet port tube also are soldered on the end plate of heat exchanger, thereby obtain the circulation road of pressure-tight on the shell-side of heat exchanger.Like this, the port holes of heat exchanger plate will be fixedly connected on the end plate.Because heat exchanger plate will react fasterly to thermal change than end plate, thus on the joint between inlet and outlet and the heat exchanger plate with stress application.If this connection stands thermal cycle, for example depend on the distance between inlet and the outlet, this connection will damage and may rupture at last.
Therefore, the heat exchanger of innovation is provided with many compensating plates 20 that are arranged between first end plate 6 and the folded group 17 of heat exchanger plate.The purpose of compensating plate is to allow that heat exchanger plate expands or shrinks owing to variations in temperature fast, and the joint between heat exchanger plate group and the end plate is not caused heat fatigue.Fig. 4 has shown the side view of compensating plate 20, and Fig. 5 has shown the cross section of compensating plate, and Fig. 6 has shown the cross section of the inlet region of heat exchanger.
Compensating plate 20 is provided with concentric wavy pattern, and it comprises convex ridge 18 and groove 19.It is corresponding that thereby this pattern is pressed the compacting degree of depth of the height distance that makes between convex ridge and the groove and plate.Compensating plate has the datum level that is denoted as a, wherein suppresses the degree of depth corresponding to height h.In the example shown, groove is positioned at datum level a place.The neighboring 22 of compensating plate also is positioned at datum level a place.The circumference 31 of each port holes 23 in the compensating plate will have the height identical with convex ridge, i.e. height h.When compensating plate is assembled into the folded group of compensating plate 21, is reversed every a compensating plate, thereby makes the neighboring of two adjacent compensating plates abut against each other, and make that the circumference of the port holes of two adjacent compensating plates abuts against each other in addition.Simultaneously, the convex ridge of two adjacent compensating plates abuts against each other, and the groove of two adjacent compensating plates abuts against each other in addition.
Only circumference 31 places of 22 places and port holes 23 connect by for example welding or soldering compensating plate in the folded group 21 of compensating plate fixed to one anotherly in the neighboring.The convex ridge of corresponding adjacent compensating plate or groove also will abut against each other, but will can not connect fixed to one anotherly.
The angle of the flank α of compensating plate can be less than the angle of the flank β of heat exchanger plate.Usually, the angle of the flank β of heat exchanger plate is approximately 45 degree, so that big heat-transfer area is provided, and provides the plate of relative stiffness simultaneously.By selecting concentric pattern, obtained low relatively radial rigidity for compensating plate.Utilize little angle of the flank α, further reduced radial rigidity.Angle of the flank α between 10 degree and 30 degree is preferred.The low radial rigidity of compensating plate is favourable.
In Fig. 6, shown the arrival end oral region of heat exchanger.In this example, in the folded group 21 of compensating plate, seven compensating plates have been used.First compensating plate is fixedly attached on the inlet tube 24 by for example welding and/or soldering, and inlet tube 24 is welded on again on the end plate 6.Circumference 31 places of continuous compensating plate 22 places or port holes 23 in the neighboring connect fixed to one anotherly.Last compensating plate is fixedly connected on the folded group 17 of heat exchanger plate at 22 places, neighboring of compensating plate 20 and 9 places, neighboring of heat exchanger plate.Between compensating plate, in plate side stream passages and shell-side circulation road, all will have very limited stream because wavy pattern be the symmetry and do not design for heat transfer.The convex ridge of a plate is resisted against on the convex ridge of adjacent panels, and for every a plate, the groove of a plate is resisted against on the groove of another adjacent panels.Because the concentric pattern of compensating plate does not have the corrugated part that intersects in the folded group of compensating plate.Port of export oral region is with similar arrival end oral region.
The effect in the following manner of the folded group 21 of compensating plate.Fast and high temperature takes place in heat exchanger rise, the heat exchanger plate in the folded group 17 of heat exchanger plate will expand immediately.It is many that end plate 6 will expand slowly, partly because end plate is much thicker than heat exchanger plate, and partly because end plate contacts considerably less with the medium that flows through heat exchanger.Compensating plate will expand slowly slightly than heat exchanger plate, because most of compensating plate is not in big contacting with the stream that flows through heat exchanger.
When heat exchanger plate expanded, the folded group of compensating plate can not expand in an identical manner, because compensating plate is fixed on the end plate.Because concentric pattern, the mode that compensating plate can be different from heat exchanger plate expands, and will expand with the shape of slight oval shape.Because the folded group of compensating plate is connected on the folded group of heat exchanger plate on the one hand, and is connected on the end plate on the other hand, each compensating plate will slightly differently expand.Each plate thereby will help reduces to be applied to inlet tube 24 and the stress on the joint 25 between the port holes circumference 31 of the compensating plate of close end plate to greatest extent.Because compensating plate has relatively low radial rigidity, thus owing to putting on stress on the plate, thermal expansion will be assigned on the folded group of complete plate, and the stress that puts on each plate will be assigned on each plate.
Complete heat exchanger core remains in the correct position by end plate, and it comprises folded group 17 of heat exchanger plate and the folded group 21 of one or two compensating plate.Because all plates all weld together,, and can only expand towards shell in the radial direction so this core is a rigidity.When core was installed in the heat exchanger shell, other form of distortion was impossible.If core is not installed in the heat exchanger, the distance that enters the mouth so between axis 34 and the outlet axis 35 will increase along with higher temperature.Because core is fixedly attached on the end plate, so the distance between inlet axis 34 and the outlet axis 35 can not change when variations in temperature.On the contrary, on the joint between core and the end plate with stress application.
The stress that puts on the joint between core and the end plate will be identical for the embodiment shown in two.Because heat exchanger core is crushed between the end plate, so tube inlet or outlet are not positioned at which side of inlet stream pipeline or outlet stream pipeline, stress all will be identical.
In second embodiment of the compensating plate shown in Fig. 5 and Fig. 6, compensating plate 20 is provided with the hole 28 that is positioned at the compensating plate center.This hole can cut out during the compacting of compensating plate or in the processing step subsequently.Utilize the hole at compensating plate center, also must be welded on the adjacent compensating plate, thereby the passage that obtains to seal is to be used for the plate side stream passages at inner rim 27 places every a compensating plate.The advantage that has the hole in compensating plate central authorities is the radial rigidity that has further reduced compensating plate.
In order to support heat exchanger plate, centre bore 28 must be provided with certain bracing or strutting arrangement to be used to support the center of heat exchanger plate.For this purpose, provide pressing plate 29 at the center of each compensating plate.Because pressing plate 29, it is favourable using otch for centre bore.For the processing that is beneficial to compensating plate and the assembling of heat exchanger, pressing plate preferably is connected on the compensating plate.A kind of mode that pressing plate is connected on the compensating plate is by welding.The neighboring of compensating plate and inner rim are seal weldings, thereby obtain the welding of pressure-tight.Pressing plate is preferably received on the compensating plate at the several position tack welding, thereby obtains flexibly connecting of pressing plate.Pressing plate should not be connected on the compensating plate rigidly.
During the compacting of compensating plate, between pressing plate and compensating plate, also can keep several slab bridges 26.Slab bridge 26 thereby compensating plate is connected on the pressing plate.Like this, pressing plate and compensating plate will can not separate fully.This will help the processing of compensating plate, but may disturb inner rim connection each other.All pressing plates can also be connected in the pressing plate unit, this pressing plate unit is assembled on the heat exchanger separately.The bracing or strutting arrangement of other type also is feasible.
The quantity of employed compensating plate can be depending on the thickness of the designed temperature that is used for of diameter, heat exchanger of heat exchanger for example and compensating plate and the compacting degree of depth and changes in the folded group of compensating plate.The suitable quantity of compensating plate of heat exchanger that is used to have 1 rice diameter is between 3 and 9.In the example shown, 7 compensating plates have been used.By using considerably less compensating plate, the stress that puts on the joint between inlet tube and the compensating plate will be very high.By using very many compensating plates, in heat exchanger, can waste unnecessary big volume, because the folded group of compensating plate is not the part of the heat-transfer area of heat exchanger.
The present invention is not regarded as being limited to the foregoing description, and many extra variants and modifications all may drop in the scope of appended Patent right requirement.
