The specific embodiment
Motor vehicle 1 shown in Fig. 1 comprises internal combustion engine 2, and this internal combustion engine comprises the waste gas system 3 that downstream connect, and in this embodiment, this waste gas system is provided with waste gas evaporimeter 5, catalyst 6, center muffler 7 and rear portion muffler 8 in a waste gas branch line 4.Motor vehicle 1 is supported on the carriageway surfacing 10 with four wheels 9 (only illustrating through reference number is exemplary here), and according to shown in Figure 1, this carriageway surfacing is positioned on the plane at paper place.
In addition, as shown in Figure 1, this waste gas evaporimeter 5 and so-called rankine cycle (Rankine-Kreislauf) 18 thermal couplings.Rankine cycle 18 has at least one evaporimeter 5, expander 19, Rankine condenser 20 and pump 21.The working media of rankine cycle (for example water) increases to the elevated pressure level through pump 21.Then, this medium flow in the evaporimeter 5.This working media flows out from this evaporimeter again, and flow in the expander 19, in this expander, makes working media accomplish machine operation, and extends to lower temperature and pressure level.Working media is flow in the Rankine condenser 20 by expander again, and in this Rankine condenser, working media is liquefied.Subsequently, pump 21 begins to draw working media once more.
First embodiment according to fluid course plate 12a of the present invention and 12b has been shown in Fig. 2 a to 2d, when these two fluid course plate assemblings, has formed a fluid course plate unit 12; These figure also show cover plate 11. Fluid course plate 12a and 12b have a plurality of openings 17; The width of each opening of this two boards is different; Therefore when these stack of plates together the time (shown in Fig. 2 d), issuable any burr can be meaningless (do not unnecessarily) not hinder interconnecting of these plates.The top of these two blocks of fluid course plates and bottom are covered by cover plate 11.According to the present invention, comprise that the unit of fluid course plate unit 12 and cover plate 11 compositions is represented with panel element 15.
As shown in Figure 3, if utilize this plate member 15 to be assembled into stacked structure, that is, make plate member 15 and alternately stack setting of flank 16, and then they are welded to each other together; This has just formed a waste gas evaporimeter so.
The waste gas evaporimeter has inlet 13 and outlet 14, looks up from vertical, in the middle of this entrance and exit is arranged on substantially.13 flow into the collection flow channels 13a from entering the mouth from the fluid (for example water) of Clausius-rankine cycle, this collection flow channels is made up of panel element 15 and the intermediary element 13b that is plugged between the panel element.
Fluid is assigned to each panel element from collection flow channels, and, in case fluid is flowed among the second collection flow channels 14a, then flow out evaporimeter via outlet 14.The second collection flow channels 14a is made up of each panel element 15 and the intermediary element 14b that is plugged between the panel element equally.These two collection flow channels 13a and 14a are arranged on the side of evaporimeter, thereby second fluid can not hindered along the circulation of flank 16, and this second fluid refers in particular to the waste gas of motor vehicle.
Fig. 4 to Fig. 6 shows the principle schematic according to another embodiment of fluid course plate of the present invention unit 12; Unit 12 perhaps can comprise two fluid course plate 12a and 12b; In this case, each bar fluid course 17 is processed (like Fig. 2 a to Fig. 2 d) through Sheet Metal Forming Technology; Perhaps can be made up of an independent fluid course plate 12a, in this case, fluid course is processed through deep-draw technology.
Embodiment by Fig. 4 can know, in the input pipe that passes to passage 17 25, is provided with pressure loss element 28, and this pressure loss element illustrates with " dp ".The pressure loss element for example is designed to nozzle or diaphragm, through this pressure loss element 28, can regulate pressure loss targetedly, in process subsequently, brings more uniform medium to distribute thus, and this will be elaborated hereinafter.
As shown in Figure 5, the waste gas evaporimeter has three zones, and these zones are distinguished each other especially thus, that is, working fluid has the different phase state in each zone.Working fluid overwhelming majority in crossing cool region 22 is in liquid condition, and the overwhelming majority is in two-phase state in evaporation region 23, in superheat region 24, then is in evaporating state fully.Produce different flows speed thus, caused pressure loss in various degree, pressure loss begins to increase gradually from crossing cool region.
Because the setting of pressure loss element " dp ", make via zones of different 22 to 24 the pressure loss difference reduce with the form of percentage.This method has guaranteed that more uniform medium distributes.Ratio between the pressure loss in initial pressure loss and the remaining fluid circulation road 17 should be between 0.25 and 1.
Because the low quality stream through being caused by the extra gross pressure loss via evaporimeter 5, the power of pump 21 only improve with minimum degree, therefore, extra pressure loss can not produce any bigger infringement to the gross efficiency of Clausius-rankine cycle.
In another embodiment according to Fig. 5, many fluid courses 17 can be arranged in the superheat region 24 in parallel connection.The increased pressure loss can be offset through the flow cross section of the increase of realization thus equally.
According to the difference of selected working fluid, the level of mass flow is different.For example, as shown in Figure 6, the fluid course 17 that laterally arranges is suitable for alcohol.
Fig. 7 and Fig. 8 show two special preferred embodiments according to waste gas evaporimeter of the present invention.In the specific embodiment according to Fig. 7, fluid course 17 utilizes deep-draw technology to be pressed among the fluid course plate 12a.The top of passage 17 is by 11 sealings of first cover plate.This plate forms plane formula with unshowned flank and is connected.In order also to be formed for the plane of flank 16 in the bottom, fluid course plate 12a is inserted in second cover plate 11, and this second cover plate carries out deep-draw on the edge of to be handled.
In some cases, can remove second cover plate 11, so that the direct abutment ribs 16 of fluid course plate 12a.
Be that with essential distinction fluid course plate unit 12 clearly comprises two fluid course plate 12a and 12b according to the embodiment of Fig. 8 according to the embodiment of Fig. 7.Through these two fluid course stack of plates are formed the cavity as fluid course 17 together.
If necessary, in this specific embodiment, equally also can save second cover plate 11 that is positioned at the bottom.
Through test of many times, draw following preferred geometric parameter especially:
0.5mm≤h≤3mm is preferred: 0.8mm≤h≤2mm;
1.0mm≤b1≤8mm is preferred: 3.0mm≤b1≤5mm;
1.0mm≤b2≤8mm is preferred: 3.0mm≤b2≤5mm;
Wherein, make: b2＜b1;
0.5mm≤c1≤3mm, 0.5mm≤c2≤3mm; Wherein, make: c1＜c2;
The thickness of cover plate 11 is preferably 0.5mm to 0.8mm.The thickness of at least one block of fluid course plate is preferably between 0.3mm to 0.7mm; That is to say that the thickness of this at least one block of fluid course plate can be less than the thickness of at least one cover plate.
Fig. 9 and Figure 10 (wherein, Figure 10 shows concrete structure figure) show another embodiment according to waste gas evaporimeter of the present invention.In this specific embodiment, fluid course 17 is made up of parallel reinforcement, and these reinforcements are via opening 27 circulation connection each other.Preferably, these openings form through Sheet Metal Forming Technology.Through the opening or the impenetrating mouth of punching press, turning to of fluid course can be set ideally.Similar with specific embodiment according to Fig. 5, in superheat region 24, can two or more fluid course be set parallel connection, thereby the elevated pressure loss is reduced.
