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 connects, 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 carriageway surfacing 10 with four wheels 9 (only illustrating by reference to numerical example here), and shown in Fig. 1, this carriageway surfacing is positioned in 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 stress level of rising by pump 21.Then, this medium flow in evaporimeter 5.This working media flows out from this evaporimeter again, and flow in expander 19, in this expander, makes working media complete machine operation, and extends to lower temperature and pressure level.Working media is flow in Rankine condenser 20 by expander again, and in this Rankine condenser, working media is liquefied.Subsequently, pump 21 starts to draw working media again.
In Fig. 2 a to 2d, illustrated according to the first embodiment of fluid course plate 12a of the present invention and 12b, when this two fluid course plate assemblings, 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 sheetpiles stack (as shown in Figure 2 d), issuable any burr can not hinder interconnecting of these plates in meaningless ground (do not unnecessarily).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 that fluid course plate unit 12 and cover plate 11 form represents 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.
Waste gas evaporimeter has entrance 13 and outlet 14, looks up, in the middle of this entrance and exit is arranged on substantially from vertical.Fluid (for example water) from Clausius-rankine cycle flow into collection flow channels 13a from entrance 13, and this collection flow channels consists of panel element 15 and the intermediary element 13b that is plugged between panel element.
Fluid is assigned to each panel element from collection flow channels, and, once fluid is flowed in the second collection flow channels 14a, via outlet 14, flow out evaporimeter.The second collection flow channels 14a consists of each panel element 15 and the intermediary element 14b that is plugged between 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 according to the principle schematic of another embodiment of fluid course plate of the present invention unit 12, unit 12 or can comprise two fluid course plate 12a and 12b, in this case, each fluid course 17 is made (as Fig. 2 a to Fig. 2 d) by Sheet Metal Forming Technology; Or can consist of an independent fluid course plate 12a, in this case, fluid course is made by deep-draw technique.
From the embodiment of Fig. 4, in passing to the input pipe 25 of passage 17, be provided with pressure loss element 28, this pressure loss element illustrates with " dp ".Pressure loss element is for example designed to nozzle or diaphragm, by this pressure loss element 28, can regulate targetedly pressure loss, brings thus more uniform medium to distribute in process subsequently, and this will below be elaborated.
As shown in Figure 5, waste gas evaporimeter has three regions, and these regions are distinguished each other especially thus, that is, working fluid has different phase states at regional.Working fluid in crossing cool region 22 overwhelming majority in liquid condition, in evaporation region 23 overwhelming majority in two-phase state, in superheat region 24 completely in evaporating state.Produce thus different flowing velocities, caused pressure loss in various degree, pressure loss starts to increase gradually from crossing cool region.
Due to the setting of pressure loss element " dp ", make via zones of different 22 to 24 the poor form with percentage of pressure loss reduce.This method has guaranteed that more uniform medium distributes.Ratio between pressure loss in initial pressure loss and remaining fluid circulation road 17 should be between 0.25 and 1.
Due to the low quality stream that the gross pressure loss via evaporimeter 5 by by extra causes, the power of pump 21 only improves with minimum degree, and therefore, extra pressure loss can not produce any larger infringement to the gross efficiency of Clausius-rankine cycle.
According in another embodiment of Fig. 5, many fluid courses 17 can be arranged in parallel in superheat region 24.The pressure loss increasing can be offset by the flow cross section of the increase that realizes 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 be arrangeding in parallel is suitable for alcohol.
Fig. 7 and Fig. 8 show according to two of waste gas evaporimeter of the present invention particularly preferred embodiment.According in the specific embodiment of Fig. 7, fluid course 17 utilizes deep-draw technique to be pressed in fluid course plate 12a.The top of passage 17 is by the first cover plate 11 sealings.This plate forms plane formula with unshowned flank and is connected.In order to be also formed for the plane of flank 16 in bottom, fluid course plate 12a is inserted in the second cover plate 11, and this second cover plate carries out deep-draw processing on edge.
In some cases, can remove the second cover plate 11, so that the direct abutment ribs 16 of fluid course plate 12a.
According to the embodiment of Fig. 8 with according to the essential distinction of the embodiment of Fig. 7, be, fluid course plate unit 12 clearly comprises two fluid course plate 12a and 12b.By these two fluid course sheetpiles being stacked to the cavity forming as fluid course 17.
If necessary, in this specific embodiment, equally also can save the second cover plate 11 that is positioned at bottom.
Through test of many times, draw especially following preferred geometric parameter:
0.5mm≤h≤3mm, preferably: 0.8mm≤h≤2mm;
1.0mm≤b1≤8mm, preferably: 3.0mm≤b1≤5mm;
