Description

Heat exchange bar The invention relates to a Wärmeauatau®cher for Flui- the, preferably for liquid fluids, especially oil, with at least one flow chamber for the LIWende ®der to be warming fluid, in which there is a conductive element to conduct of the fluid is located, wherein the Durchflußmmer at least has a heat passage wall through which the heat exchange "ch takes place. For the purposes of the invention, the Expression fluids in both gaaf-shaped and liquid Fluids. . In particular, the invention relates to Wärmeaua- tauacher for liquid fluids, e.g. B. on oil coolers at @ motor vehicle witness or the like. With that too. cooling oil can be both about engine oil and looking for the oil from automatic ara working torque converters or the like & change. Which he- Finding is by no means restricted to this. She concerns rather, general heat exchangers for any application areas in which attention is paid to a high degree of efficiency. The efficiency is defined here as W /, ä p #F, where W the Heat exchange chleiatuxig per unit of time ,, p the pressure drop. of the fluid to be cooled or heated and F die Is the area of the heat transfer wall and this efficiency under the same physical conditions on the same structure - th Wärmeauetauechern is measured, which is only through different design of the Leiteinaatzes distinguish. A known Wärmeauatauecher has one made of sheet metal molded.

Also is the efficiency relatively unfavorable and the production of the ze® relatively difficult and complicated. Furthermore, a cooling pipe Leiteineatz is already acknowledged, which consists of a web of material that consists of a metal sheet is cut out and in the case of incisions and turns of cut-limited tongues flow deflecting guide surfaces as Individual ribs are formed, with the folding lines of the..Zunm gen run obliquely to the pipe axis and with the inner surface of the Cooling tube are metallically connected in a known manner (German 'Patentschrift' 8 126 431). However, one shows heat Exchangers with this lead mission also have one. relatively poor efficiency on o Also need to achieve a some dimensions of sufficient power, the non-bent surfaces cross the sheet completely with the neighboring worm. - the wall must be soldered, otherwise the heat transfer preventing cavities. Also: this makes the effective Thickness of the heat transfer wall over a considerable area Reinforced area by the thickness of the Blechaa. . Einwei-Eerer well-known Wäeaustenscher, who as a double pelmentela tube heat exchanger is also formed, has a Guide insert e.uf, x of the slotted ans plates be4 r stands for the material lying between the slots is bent out to the right or left, so that the Plates of parallel extending and undulating vera running strips are made with the slits straight run and the left and right out Parts are connected by median strips and the strips are calibrated seen in a perpendicular to the continuous surge Direction 'as a series' of im. essentially hexagonal present honeycombs (German Auslegeschrift '8 1®4 542). This heat exchanger has a relatively high: current, .. mungswideretand, since it often makes the flow at right angles distracts and directs the tele-currents against each other: Further is the height of the vertebrae ataes for manufacturing reasons relatively narrow. The invention has for its object to provide a u. Warmth- To create exchangers, the disadvantages of the known Wärmet exchanger does not have. In particular, it is a goal of Invention of a heat exchanger with a high degree of efficiency, d: h. with a large heat evacuation at low To set up pressure loss. E® is also an aim of the invention, Creating a lead insert for heat exchangers that is easy and to be economically manufactured with great accuracy, stable and is easy to assemble. The invention also aims to create a guide insert for single-jacket tube heat exchangers fen, which is simple in construction and with great pressure a heat transfer wall for the production of a .guten höt or Contact connection can be pressed. To solve this problem, a heat exchange Shear of the type mentioned proposed according to the invention, that the guide insert for splitting the flow of the fluid into a plurality. of partial flows of different flow direction. that under constant re-encounter and renewed Split up with alternating impact and re-emergence away from the heat transfer wall (s) through the through flow chamber wind, a multitude of parallel to the heat® extending through the wall, in the direction of the thermal has gangway to open guide cells, each of which is time, walls, namely _ a front wall and a front wall, has, which in relation to the pluidum flow one of the Le @ - th the fluid circulation serving Eau or, form Meck., where Bow and stern each have at least two partial ducts inclined towards each other have walls, the ®der of which the neighboring heat throughƒ Side fenders facing gangways on at least one Part of your IAnge at a distance from the thermal wall and - preferably at an angle to the Zärmed @ arcang @ rand s® that the inflow and outflow -of fluids in or out of the Interior of a guide cell in several directions over the open the side edges of the bow and stern under supervision of the relevant fenden partial flows takes place at the Würmed Durchgangsivand, and deß also preferably catch and (deck of the guide cell by at least a connecting member, preferably at least one side wall, are connected to each other. It turned out that there was one such event Has surprisingly high efficiency. In particular is his. Flow resistance is low and the fluid is splitting and remixing the streams of parts, 'whereby the se partial flows again and again on the wall through the wall impinge, in particularly favorable heat transfer connection with brought the heat throughput. `The guide cells can be any gee: @, ete: - * uabildüng show, if they are just s® aaunebldet -, that the bow of everyone Leitzelle the Fluidumssträmung in a plurality of'Tellströmungen different directions and inclinations. the in then Interior of the control cell and / or in adjacent control cells possibly with others.

This means the serving .Teilleitwände as particularly evident au® Pig.20 $ u can be seen, are so inclined relative to each other :, that In Drautei®ht and Uutenaneioht (similar to 718.20) their 3 are visible bind, in Pig. 20 each part of the wend, like 104 .. 107, essentially. even, and their normal ", aet- sen _ made up of three. ®corresponds to each other a number of constituents ®names, * na them. one in gaüetrömurigsriohtung, one xei- tere paralel leur bena ih bert "en heat vest" and a® y Third ned, i cre®ht to the adjacent thermal barrier wall. The Dargtstellung_gepig.22 and 23. shows a brandy liquor the time required according to Fig. 17. The modification concerns the Compression of the upper edges 91 ° of the partial guide walls of the Bugs or hedge. By pressing the upper edges together a reduction in the flow resistance and an improvement the effect gradea achieved In Fig. 24 it is shown how the riding use after Fig: 22 is expedient to train if he is for a Durohflussm Chamber is provided with two parallel thermal barrier walls. In this case the lower edges, like 91 °°, are like that too upper edges 911 pressed together. The riding stake shown in Pig. 25 and 26 can 'dem Guide insert according to Fig. 17, 18 with the only difference being speak that the upper side edges delimiting the opening 95 th 109 of the part guide walls, such as 110, are not flat, so that the height of the opening, such as 95.1. changes nonlinearly. The lower Side edges 111 of the part guide walls 110 are formed so that this is called a sheet metal plate, which is exclusively needs to be slotted can be made. In Fig. 27 an expedient design of the guide element $ ea according to Pig. 25 for the case of a flow chamber with two pa- shown. By this measure is the formation of spikes: Wärmedurohgange- wall avoided. The variant shown in Pig. 28 and 29, the time some at $ ee according to Pig.17, 18 $ eiohnet by the fact that the Partial baffles like 112, no.au® are formed: that the Thermal passage wall $ 6 adjoining passage openings 113 greater than - the one adjacent to the lower level 1 14 # - Entrance openings. 113o ei-ad. The boundary wall 114 would in the rim of a single tube of the wall the core, as in 21 (Fig. 3). However, this lead inlay is suitable for but also for one. Casing tubes without a core. The Iteiteineatz shown in gig. 30 anno 31 can in all details the guideline shown in Fig. 17 and '8 8 use with which correspond to some difference, sat the front right curve like 113, each guide cell still has a slope at an angle to the front, as is particularly clear from 719.31 can be seen, while the rear Mbung, like 116, in a on the Wärmedurceng®w®nd 86 vertical direction en-: det. Furthermore, since the lower tip 117 each® bend on the upper Tip 118.d.® is attached to the adjacent horizontal bar and the upper Rent the bow is flattened similarly as in Fig.17, results calibrate here, that the bow has a contact with the heat transfer has gangway through which a through the stern on the bow The extreme pressure exerted 117 is absorbed by the system without the risk of kinking® the® bugs. This is particularly advantageous when expanding the® leading instru- zeo, as this means that the initial start-up without the risk of subsequent tolerable undesirable deformation with great force to educate development of a good contact connection with the heat transfer wall aüfgedorntp ie call can be expanded .. In Pig. 32 there is a variant according to the lead insert 3A, 31, the differences of which $ u Pigo31 are teres are recognizable, so that they are not explained in more detail. This time commitment has the same advantages as the lead mission according to Pig. 31, but with a plant that is twice as large 99, 140 is provided. Here too is that Investment basis made so that the time invested with great force can be pressed against both heat transfer walls without da8 there is a risk of unexpected deformation. The T, shown in FIGS. 33 and 34, is made up of a large number of neten baffles according to Fig. 5, 6, with adjacent rows, like 119, connected in one piece by connecting pads, like 120 are. The connecting webs extend here parallel to the Main flow direction and weep practically no flow deretanä on. This also results in a large number of managerial cells, such as 1219 where each vane is connected by two gen 180 and partial baffles, such as 122 and 125, is limited. This Ireiteinoats corresponds in its effect to a in connection with the units described in fig. 1 - 3, in which wellenförw rustic or siokimokiö = ige, diagonally to the gauptetröadungsriohtung sheet metal strips inclined towards the värmedurobgengswend - at a distance 'from- are arranged to each other. The time input shown in Vig. 35 and 36 is from a sheet metal plate by slitting and bending open lap- pen as made 1261, 127. The bet has a lot of number of guide cells, such as 128, on whose Bü $, such as 129, and stern, like 1309 with a perpendicular to the longitudinal axis 166 and here parallel lel too. a non-illustrated thermal barrier wall extend- the web 131p are connected.

The sighted ducks of the Teilleit® walls run obliquely to the warmth as in Pig.5, 6. durohgangewando This time commitment also shows an excellent have an effect with simple manufacture. Also in this- In this exemplary embodiment, the bow and the beok are as in the previous the äusfUhrungsbeispielen formed at an acute angle. This is in general particularly advantageous, in special cases can also an obtuse-angled training would be an advantage, special. then, if the surfaces of the single cell walls are of a relatively Wrest angle of incidence In the main flow direction for the heat transfer gengsyrand have. - In the execution example according to 6g.37 and 38 is a Leitelneat is shown, which can be formed ähxrliah, like the? leiteinsat $ according to 1f19.33, 34, but with the webs 120 omitted and instead the front mantle the bugs one neat #. Belle about the back edge of the hedge adjoining neighboring guide point arranged iato like beeondexs can be seen clearly from Fig. 38, are with the kinks, like 135, 136, through notches 138 are provided, whereby a special over-edged, for the properties of the use of time cheap Weküng de® concerned wedge-shaped bugs or stern -is obtained. The one in the Fis. 39 and 40 @; @ dergentelte hoiteinnats is similar to d,:.% time units according to Pig. 37, 38, where , but the bow and stern of the neighboring guide cells, such as 139, in the stood from their tips, like 141, 142, sufeir. are changed. Under points here are the front and rear edges understood from bow and deck. Serve training de® Iaeiteine®teeo has among other things: Aen Törteilt that the time cells are calibrated with the formation of partially overlap due to the fact that the Geeamtober-- fläohe an I oK tein «tsee is enlarged even further.
