Definitions
- Heat exchangers in particular oil coolers
- the invention relates to a heat exchanger, for example an oil cooler, having the features of the preamble of claim 1.
- a pressure-responsive valve is provided as a flow control means that is located at an opening of the local distribution channel.
- the function of the valve is to allow cold and therefore still viscous oil, the pressure of which is correspondingly high, without having to pass through the channels of the heat exchanger, bypassing the heat exchanger in the manner of a bypass.
- the oil in the heat exchanger is not cooled and can reach its operating temperature faster. If this temperature is reached, the oil is thinner, the
- the heat exchanger from the cited document also has sealant. These are rubber seals that surround the openings of the collecting channel like a ring and seal it to a gearbox. The flow directing means and the sealant must be attached to it after soldering the heat exchanger.
- An oil cooler is known from EP 1 772 693A1, in which a pressure-responsive valve is also provided as a flow-directing means, which, however-in contrast to the prior art described above-is already inserted and soldered into the heat exchanger before soldering. Sealants have not been addressed in the document, but they should be part of such heat exchangers on a regular basis.
- the object of the invention is to simplify the manufacture and optionally also the assembly of the heat exchanger.
- the flow directing means is preferably a pressure change responsive valve.
- the flow director is a rigid element which can only direct the flow in a particular desired direction.
- the common component is also attached to the heat exchanger, so that it can not be lost in the course of further production or assembly.
- Fig. 1 - a perspective view of an oil cooler, partially in exploded view
- Fig. 2 is a view of the oil cooler of Figure 1 in a different perspective
- Fig. 3 another common component
- Fig. 4 - a longitudinal section through the base plate of the oil cooler
- Fig. 5 is an enlarged detail showing the common component
- FIG. 6 and 7 - a third embodiment in perspective views
- a so-called caseless heat exchanger is shown as an oil cooler, whose plates 1 have four openings 10.
- the openings 10 - only two are visible - form a collection channel 12 and a distribution channel 11 for the incoming or exiting medium, in this case for the oil.
- these channels 11, 12 go between the plates 10 arranged other channels, which are also not visible in the drawing.
- arrows have been drawn in order to indicate that a liquid coolant flows in and out at the top.
- the oil flows in and out at the bottom, as indicated by the dashed lines. Because of the embodiment described so far can also be used on the references mentioned above, because it is well known.
- the oil cooler is connected to a not shown unit, for example to a gearbox or motor housing, whose oil is to be cooled or tempered.
- the base plate 20 consists in the embodiment shown of three flat plates 20a, 20b, 20c.
- a common component 50 is arranged, which comprises a sealing means 30 and a flow-guiding means 40.
- the common component 50 is in the embodiment of metal, for example, a grade 1 4310 stainless steel, which also has suitable elastic properties.
- the sealant 30 is formed in the manner of a metal bead seal. In Figs. 6 and 7, the circumferentially formed bead 31 can be seen.
- the flow-directing means of the common component 50 is here a pressure-responsive valve 40.
- the valve 40 In Figs. 1 and 2, the valve 40 is in the closed position. In this position, the sealant 30 and the valve 40 are approximately in one plane.
- the common component 50 can be produced by simple forming steps. As an advantage of this arrangement may also be stated that the attachment of the common component 50 made after soldering the oil cooler can be without requiring any insertion openings for the valve 40, which would have to be closed again after insertion.
- a rigid element was provided as a flow control means 40, by means of which, for example, the flow passing through the channels can be directed to otherwise poorly flowed plate areas or - more generally and in other words - to influence the flow.
- the common component 50 has bent hooks which serve as fastening means 60 and which engage in corresponding slots 61 or the like in the base plate 20. Thus, the common component 50 is fixed in position and can not be lost in the course of further processing.
- the sealing means 30 and the flow control means 40 consist of an identical material but rather it depends on the commonality of the component 50.
- the sealing means 30 may consist of a suitable rubber on which the flow-guiding element 40, which consists for example of metal, is vulcanized. All this is just a matter of cost and convenience in a particular case.
- the valve 40 could also be a bimetal, which is known to have the property of responding to temperature changes.
- the base plate 20 already described above as having three parts, has in its middle plate 20b an elongate channel which acts as a bypass channel 5 and is arranged in a very space-saving manner.
- the plates of the base plate 20 are formed comparatively thin-walled.
- This bypass channel 5 is connected on one side with the distribution channel 11 in connection.
- the bypass passage 5 communicates with an aperture 21 disposed in the lowermost plate 20c.
- the breakthrough 21 is closed by the valve 40 during normal operation of the oil cooler, so that the oil must flow through the channels, not shown, between the plates 1, thereby cooled by means of the other not shown channels between the plates 1 cooling liquid before it leaves the oil cooler via the collection channel 12 again.
- FIG. 5 shows exactly this situation, namely the valve 40 in the open position. In this position, the valve 40 is at an acute angle to the plane of the sealant 30. Further, Fig. 5 shows that it is expedient to form the valve 40 with a planar formation 41, which is adapted to the dimension of the opening 21, whereby the Sealing effect of the valve 40 can be improved.
- the training proposed here is also applicable in a combination of the oil cooler with an oil filter.
- the valve 40 could be as mentioned above - be responsive to temperature changes of the coolant valve.
- FIGS. 6 and 7 now show another exemplary embodiment which is advantageous for some applications, which differs from the exemplary embodiment already described in that the common component 50 extends over almost the entire surface of the base plate 20.
