Definitions

  • the invention relates to a gas-cooled heat exchanger, in particular a direct intercooler, for cooling a fluid which can be flowed through the heat exchanger, with a heat transfer block having a plurality of flow channels, with a first collection box and with a second collection box, wherein the collection boxes are fluidically connected to one another via the flow channels and the heat transfer block is flowed through by a gas outside.
  • intercoolers are used in modern motor vehicles.
  • the intercoolers are used to cool an air stream, which is supplied to the engine, for example via a turbocharger or via a compressor.
  • an air-cooled exhaust heat exchanger which has a covering device, which has adjustable elements.
  • the covering device is designed in such a way that a flow around the exhaust gas heat exchanger can be enabled or prevented by adjusting the elements.
  • a device is known in the art, which is formed by a cover, which can be positioned above or in front of the heat exchanger to reduce the flow around the heat exchanger.
  • the WO 2011/102784 A1 discloses a device which provides a flap in the interior of the charge air cooler, which leads to a limited flow through the heat exchanger.
  • devices are known in the art, which provide a permanent opening, which is formed for example by a bore on the heat exchanger, whereby the continuous flow of the resulting condensate is ensured.
  • the FR 2 922 962 discloses a device which provides a condensate recovery chamber and a discharge device via which the collected condensate can be discharged from the heat exchanger.
  • a disadvantage of the devices in the prior art is in particular that is influenced by a device of adjustable aperture elements or a cover in front of the heat exchanger usually the cooling capacity of the coolant radiator or other heat exchanger. Adjustable bezel elements also require a drive mechanism and appropriate control, which is costly and causes costly manufacturing.
  • a disadvantage of a flap installed in the heat exchanger is in particular that a control and an actuating device must be provided, which can cause activation and deactivation of the flap. This is also complex and costly.
  • a disadvantage of a collecting chamber and a drainage device for the condensate is in particular the structural integration of the elements in the existing parts. This can lead to significant additional costs,
  • An embodiment of the invention relates to a gas-cooled heat exchanger, in particular a direct charge air cooler, for cooling a fluid which can flow through the heat exchanger, with a heat transfer block having a plurality of flow channels, with a first collection box and with a second collection box, wherein the collection boxes fluidly communicate with each other via the flow channels Connected and the heat transfer block is flowed through by a gas outside, wherein in the flow direction in front of the heat exchanger block an aperture element for the area-wise prevention of the flow around the flow channels thereof is arranged, wherein one of the collecting tanks has a valve for discharging condensate of the fluid to the environment of the heat exchanger lockable or releasable.
  • the gas-cooled heat exchanger is particularly advantageous flows through a fluid and flows around a gas.
  • the gas is preferably air.
  • the diaphragm element is preferably arranged on the upstream side of the heat exchanger, so that the air flow flowing around the heat exchanger is deflected by the diaphragm element and is deflected around the flow channels of the heat transfer block covered by the diaphragm element.
  • the cooling capacity is reduced in the covered flow channels, thereby effectively preventing the formation of condensate in these flow channels and the local cooling in this area is reduced.
  • the fluid flow flowing through the flow channels covered by the diaphragm element can therefore be used to blow out condensate, which is formed in the other flow channels, from the lower region of the heat exchanger, in particular the collecting tank, or to transport it to the valve, which is arranged in one of the collecting tanks is.
  • valve is arranged in the collecting box, which is located downstream of the heat transfer block in the flow direction of the fluid.
  • the arrangement of the valve in the downstream in the flow direction of the fluid collecting tank is particularly advantageous because it can be achieved that the resulting condensate is entrained by the flow through the flow channels towards the valve.
  • the fluid flow through the flow channels covered by the diaphragm element can advantageously entrain the resulting condensate in the direction of the valve.
  • a preferred embodiment is characterized in that the valve is arranged to the longitudinal end of the collecting tank spaced from the outer flow channel of the heat transfer block in the collecting box.
  • the arrangement of the valve spaced from the outer flow channel is particularly advantageous, since in this way the entire condensate formed in the flow channels can be favored by the fluid flow within the heat exchanger and favored by gravity to flow in the direction of the valve. Also, a return flow of the collected condensate in the lowermost flow channel is thus effectively avoided.
  • valve is designed as a check valve, wherein a fluid flow through the valve from the collection box towards the environment is releasable.
  • the collecting box which has the valve at the longitudinal end region, has a funnel-shaped inner contour which forms a gradient in the direction of the valve.
  • a funnel-shaped inner contour is advantageous in order to improve the flow of the condensate towards the valve.
  • the funnel-shaped inner contour is preferably designed such that the condensate is collected below the lowermost flow channel in order to avoid a backflow into the flow channel.
  • valve is controllable in dependence on a pressure difference between a pressure in the collecting box, in which the valve is arranged, and a pressure outside the collecting box.
  • the valve releases the flow path from the collecting box to the surroundings of the collecting tank, in particular at a pressure difference between approximately 1 bar and 2 bar.
  • the valve can be actively controlled by the pressure difference is detected by suitable sensors within the heat exchanger and outside of the heat exchanger.
  • the valve can be designed by its structural design such that it automatically opens or closes at a predetermined pressure difference.
  • the valve should remain closed during idling and at low engine loads to avoid noise on the valve.
  • opening at higher engine loads can be achieved that the exhaust noise of the valve is masked by the noise of the internal combustion engine, which there is no negative impact on the occupants.
  • the cooling capacity in these flow channels can be achieved.
  • the lowermost in each case in the installation flow channels are covered by the diaphragm element.
  • a different number of flow channels can be covered.
  • the cooling capacity of the heat exchanger is reduced overall, while the number of flow channels, in which no condensate is formed, is increased.
  • the tendency for complete freezing or blocking is reduced.
  • a smaller number of covered flow channels leads to a less greatly reduced cooling capacity, while the risk of freezing or blocking of the heat exchanger is increased.
  • an optimum must preferably be found for each specific application.
  • the panel element covers at least the outer flow channel or the outer and the directly adjacent to this flow channel.
  • the flow channels are therefore covered, which are arranged at the lower end region of the heat exchanger block.
  • the condensate which is produced in the upper flow channels, which are not covered, can flow down in the collecting tanks.
  • the respective lower flow channels, which are covered by the diaphragm elements, are not so strongly cooled due to the smaller flow around the gas.
  • the formation of condensate in this area is therefore always lower than in the upper flow channels.
  • the tendency to block these flow channels as a result of freezing is much lower than in the upper uncovered flow channels.
  • the fluid continues to flow through the lower covered flow channels, whereby the condensate flowing down from above is entrained and flows to the valve in the collecting box, which is located downstream of the heat transfer block. A removal of the condensate is thus guaranteed at all times.
  • the aperture element preferably reduces the cooling power to a value between 40% and 95% of the cooling power, which can be achieved without changing the aperture element under unchanged boundary conditions.
  • a reduction in the cooling capacity in this area is particularly advantageous, since sufficient cooling capacity is still achieved for the intended use of the heat exchanger, while at the same time the tendency to freeze or block the heat exchanger is sufficiently reduced. In this way, advantageously, a heat exchanger can be created, which has sufficient reliability even at low outdoor temperatures.
  • the panel element is welded to the heat exchanger and / or clipped and / or glued and / or is screwed and / or jammed.
  • the diaphragm element may preferably be connected to the heat exchanger or the heat transfer block via different methods.
  • the diaphragm element is formed from a metallic material or a plastic.
  • the pressure of the fluid is preferably above the ambient pressure of the heat exchanger.
  • the fluid thus has a higher pressure level than the gas which flows around the heat exchanger. This is advantageous, in particular, for a heat exchanger used as a charge air cooler, since there is regularly a high pressure in the latter, which is generated by the existing turbocharger or compressor.
  • FIG. 1 shows a partial perspective view of a heat exchanger 1.
  • the heat exchanger 1 has a heat transfer block 2, which is formed from a plurality of not shown, mutually parallel tubes and interposed corrugated fin elements.
  • the tubes of the heat transfer block 2 are each end received in a collection box 3. In FIG. 1 only one of these headers 3 is shown.
  • the tubes form in their interior the flow channels 9 of the heat transfer block 2.
  • the collecting box 3 has a holding element 7 with which the collecting box 3 can be fastened within a vehicle with respect to surrounding structural elements. Furthermore, the collecting box 3 has a fastening device 6 on which a retaining device 5 formed by a rod can be fixed. The holding device 5 is used for fastening a diaphragm element 4, which covers the heat transfer block 2 at least partially.
  • the diaphragm element 4 is designed such that a certain number of the tubes of the heat transfer block 2 is covered over the entire width of the heat exchanger 1.
  • the panel element 4 extends, in particular, from the collection box 3 shown to the collection box (not shown), which is arranged at the opposite end area of the heat transfer block 2.
  • the diaphragm element 4 serves to shield the heat transfer block 2 from an air flow which flows around the heat exchanger 1.
  • the diaphragm element 4 is preferably arranged on the side of the heat exchanger 1, which is flown by a gas flowing around the heat exchanger 1. In this way, the gas flowing against the heat exchanger 1 gas is deflected up and down, whereby in particular the arranged above the diaphragm element 4 tubes and the area below the heat exchanger 1 are flowed around by the gas.
  • the heat exchanger 1 is flowed through by a fluid according to the invention.
  • a fluid according to the invention At the heat transfer block 2 creates a Vllärmeübertrag between the flowing through the heat exchanger 1 fluid and the gas flowing around the heat exchanger 1. This serves, in particular, for cooling the fluid flowing in the heat exchanger 1.
  • the fluid flowing in the heat exchanger 1 is distributed in one of the collecting tanks 3 to the tubes of the heat transfer block 2 and collected in the other from these tubes and discharged from the heat exchanger 1.
  • the heat exchanger 1 is preferably a charge air cooler, which is used to cool an air flow, which is then supplied by means of a turbocharger or a compressor to the internal combustion engine.
  • the diaphragm element 4 is in the embodiment of FIG. 1 triangular shaped and lies with the apex on the rod of the holding device 5. This results in above the holding device 5 and below the holding device 5 each inclined surfaces of the diaphragm element 4, which favor the derivation of the air flow flowing on the shutter member 4 upwards or downwards.
  • the diaphragm element 4 has in the embodiment of FIG. 1 an angled contour as a cross section.
  • the diaphragm elements 4 may also be formed as a flat plate-shaped element, which is arranged in front of a certain number of tubes.
  • the diaphragm element can also be integrally connected to the heat exchanger or be connected to the heat exchanger via methods such as welding, gluing, clamping or clipping.
  • the shutter member 4 is made of a metallic material so that it can be easily connected to the heat transfer block.
  • the diaphragm element may be formed of plastic, whereby in particular its manufacture is facilitated and the diaphragm element can be carried out particularly inexpensively.
  • the diaphragm element can preferably be produced in an extrusion process, whereby a simple production in the context of a mass production is made possible.
  • the baffle element may also include a number of openings which allow at least a partial flow around the covered tubes of the heat transfer block.
  • the diaphragm member may extend only over a portion of the heat transfer block. It is also conceivable that the panel element is divided into a plurality of individual sections, so that, for example, in each case only the end areas of the tubes facing the collecting boxes are covered.
  • the basic task of the diaphragm element 4 is to reduce the flow of the covered tubes by a certain amount in order to reduce the cooling capacity in the covered tubes.
  • the cooling capacity in the covered pipes should preferably be reduced by a proportion of 40% to 95% compared to the uncovered pipes.
  • FIG. 2 shows a sectional view through the heat exchanger 1.
  • the tubes which each form a flow channel 9
  • the tubes are arranged in parallel one above the other within the heat transfer block 2.
  • corrugated fin elements 10 are arranged, which in particular should improve the heat transfer between the gas flowing around the heat transfer block 2 and the fluid flowing through the flow channels 9.
  • the flow channels 9 are each end received in a tube sheet 8, to which a lid-like wall 11 is connected, whereby the collecting box 3 is formed between the tube sheet 8 and the wall 11.
  • the flow channels 9 thus unilaterally all open into the internal volume of the header tank 3.
  • the outlet-side collection box 3 is shown.
  • a valve 12 is arranged, which has a valve inlet side 13 and a Ventilauslassseite 14.
  • the valve inlet side 13 is directed to the inner volume of the collecting tank 3, while the Ventilauslassseite 14 is directed towards the environment.
  • the valve 12 is designed such that a fluid flow can only be realized from within the collecting tank 3 to the environment.
  • the valve 12 is used in particular for removing a condensate, which can form within the heat exchanger 1.
  • the valve 12 is for this purpose pressure-controlled and can be opened or closed in particular by the emergence of a pressure difference within the heat exchanger 1 and outside of the heat exchanger 1.
  • the valve 12 is designed such that it only opens when the internal combustion engine is operated with a predefined minimum load.
  • FIG. 2 It is shown that the upper edge of the valve inlet side 13 is arranged below a level line 15, which at the same time below the lower edge of the lowest Flow channel 9 is arranged. In this way it is ensured that the inlet to the valve 12 is always below the lowest point of the lowermost flow channel 9. This would serve to better dissipate the resulting condensate from the collecting box 3.
  • the valve 12 be located higher, a backflow of the condensate could arise in the lower flow channel 9, which in turn could lead to icing or blocking of the lower flow channel 9.
  • the collecting box may have a funnel-shaped inner contour in the region of the lower end region, which in particular may allow the condensate collected in the collecting box to flow towards the valve. In this way, a further improved removal of condensate could be achieved from the collection box.
  • the in the Figures 1 and 2 shown embodiments are exemplary and are intended to illustrate the inventive idea.
  • the arrangement or design of the diaphragm element 4 in FIG. 1 is exemplary. In alternative embodiments, other aperture elements may be provided.
  • the main task of the diaphragm element 4 is the at least partial coverage of a predefined number of tubes of the heat transfer block 2 at the lower end region of the heat transfer block 2.
