Definitions
- the present invention relates to a heat exchanger for a motor vehicle according to the preamble of claim 1.
- the document JP2001027157 discloses in Figures 4 and 5 such a heat exchanger.
- the fluid is the exhaust gas of an internal combustion engine of the motor vehicle.
- a particularly large temperature difference of typically several 100 ° C is achieved in the fluid cooling, so that the adjustment of the flow resistance of the two downstream flow paths in the course of cooling of the exhaust gas is particularly effective.
- the first flow path has a smaller flow resistance than the second flow path.
- the region of the first flow path on average there is a higher temperature difference to the coolant than in the region of the second flow path.
- a high cooling capacity is already given due to the temperature difference. Due to the temperature of at least gaseous fluids, high pressure losses are present anyway in this region, so that the flow resistance, in particular the generation of turbulence to improve the heat transfer, can be kept relatively small in the first flow path.
- the fluid is already partially cooled, so that in the second flow path to obtain a sufficient heat transfer advantageously a greater flow resistance, in particular a larger proportion of turbulent flows, is present. In this way, an overall optimization of the heat exchanger performance is achieved taking into account the lowest possible total pressure drop across the heat exchanger.
- turbulence-generating means are provided in at least one of the two flow paths, whereby the heat exchanger performance is improved.
- the turbulence-generating means are formed as protruding into the flow path formations of walls of the flow path. These may be dimples or so-called " winglets" (V-shaped aligned embossed webs).
- the turbulence-generating means may also be deposits defined in the flow path. Such inserts may be, for example, rib ribs or corrugated ribs or the like.
- all turbulence-generating agents which are known from the prior art are suitable for the purposes of the present invention. What is essential is only the different design of the flow resistances in the first flow path and in the second flow path.
- ribs are arranged to increase a contact area with the fluid, wherein the ribs in the first flow path and in the second flow path have a different density. Even in a case where, for example, are longitudinal ribs such as corrugated fins, in which predominantly laminar and less turbulent flows are formed, a different density of the ribs leads to different flow resistances.
- the flow resistances of the flow paths can therefore be influenced in principle both by generating turbulences and by influencing laminar flow fractions.
- first flow path and the second flow path may each comprise a plurality of separate, parallel flow channels.
- the number of channels of the first flow path is different, in particular smaller, than the number of channels of the second flow path.
- the channels of the first flow path can each have a different, in particular larger, cross-sectional area than the channels of the second flow path.
- the channels of a flow path have different flow resistances among one another.
- the flow resistance of an outer channel with respect to the deflection region is greater than the flow resistance of an inner channel of the same flow path.
- the first flow path preferably has a different, in particular larger, free cross-sectional area than the second flow path.
- free cross-sectional area is meant the geometric cross-sectional area for free flow of the fluid.
- the flow paths are arranged in a housing through which the coolant flows.
- the coolant is advantageously a liquid, in particular cooling liquid of a main cooling circuit of the motor vehicle. As a result, an overall effective cooling of the fluid is ensured.
- the heat exchanger comprises a connection region with a first connection for supplying the fluid to the first flow path and a second connection for discharging the fluid from the second flow path, thereby enabling a compact and cost-saving design of the heat exchanger.
- an adjusting element is provided in the connection region, by means of which a direct connection of the first connection and the second connection for bypassing the flow paths is selectably adjustable. This makes it possible to bypass the cooling of the fluid selectable, which is desired especially in internal combustion engines of motor vehicles under certain operating conditions such as the warm-up phase of the engine.
- the flow paths and / or the flow channels are made of aluminum.
- the flow paths and / or the flow channels are made of stainless steel.
- the flow paths and / or the flow channels are made of aluminum and stainless steel.
- the fluid is exhaust gas of an internal combustion engine of the motor vehicle.
- turbulence-generating means are formed as defined in the flow path deposits.
- the flow paths are arranged in a housing through which the coolant flows.
- the flow paths in particular the flow channels made of aluminum and / or stainless steel are formed.
- Fig. 1 shows a U-flow heat exchanger for cooling recirculated exhaust gas of a motor vehicle diesel engine, in which a first flow path 1 and a second flow path 2 are arranged in parallel and side by side within a housing 3.
- the housing 3 is flowed through by means of two ports 4, 5 of a liquid coolant, which is branched off from a main cooling circuit of the diesel engine.
- the flow paths 1, 2 each comprise a number of flow channels 6, 7, which in the present case are designed as flat tubes with a rectangular cross-section.
- the cross section can in principle also have another, approximately round, shape.
- the connection region 8 has a first connection 9 for supplying exhaust gas of a diesel engine of the motor vehicle and a second connection 10 for discharging the cooled exhaust gas.
- a control element 11 designed as a pivotable flap is provided, which is adjustable via a rotary shaft 12.
- the exhaust gas is passed from the first port 9 in the first flow path 1, where it first undergoes a first cooling. After flowing through the first flow path 1, the exhaust gas enters a deflecting region 13 arranged at the end of the housing 3.
- the deflection region 13 here is a substantially semi-cylindrical, hollow housing part, in which the exhaust gas flow is deflected by 180 °, after which it enters the second flow path 2.
- the second flow path 2 flows through the exhaust gas in the opposite direction to the first flow path 1, wherein it undergoes a further cooling.
- When leaving the second Flow path 2 enters the exhaust gas again in the connection area 8, where it in the case of the first position of the actuating element 11 according to Fig. 1 is guided in the second terminal 10.
- each of the flow paths 1, 2 comprises a bundle of nine flow channels 6, 7 each of rectangular cross-section.
- the outer dimensions of the flow channels 6, 7 are each identical.
- the flow channels 6 of the first flow path 1 and the flow channels 7 of the second flow path 2 turbulence generating means in the form of indentations 6a, 7a, which have a different size.
- the impressions 6a of the first flow channels 6 protrude less deeply into the channel cross section than the impressions 7a of the second flow channels 7. In this way, the geometric free flow cross section of the second flow channels 7 becomes smaller compared to the geometric free cross section of the first flow channels 6.
- more turbulence is introduced into the exhaust gas flow in the second flow channels 7 through the deeper protruding turbulence-generating means 7a than in the first flow channels 6.
- the turbulence-generating means 6a, 7a can be dimples and / or winglets. Alternatively or in addition, it may also be in itself act known structured deposits, which are inserted into the flow channels 6, 7 and welded.
- the second heat exchanger In the second heat exchanger according to Fig. 3 is the first flow path 1 as well as constructed in the first heat exchanger.
- the second flow path 2 In contrast to the first heat exchanger, the second flow path 2 not only has different turbulence-generating means 7a, but also has a smaller number of flow channels 7 than the first flow path 1, which have a different outer dimension relative to the flow channels 6 of the first flow path 1.
- the second flow path comprises fewer flow channels 7 with a larger external dimension, a greater flow resistance is generated for the second flow path 2 by the deeper projecting turbulence-generating means 7a than for the first flow path 1. Due to the changed number and outer geometry of the flow channels 7 the flow resistance of the second flow path in the second embodiment is slightly smaller than the flow resistance of the second flow path in the first heat exchanger.
- each of the flow paths 1, 2 each have three parallel flat tubes 6, 7 as flow channels, each having identical outer dimensions.
- the flow channels 6, 7 are provided with rib-like inserts 6b, 7b, whereby the contact area between the exhaust gas flow and heat-conducting metal is increased.
- fewer fins are provided in the case of the flow channels 6 of the first flow path 1 than in the case of the flow channels 7 of the second flow path 2. Due to the greater fin density of the second flow path 2 with otherwise identical dimensions and numbers the flow channels 6, 7, the second flow path 2 has a greater flow resistance than the first flow path 1.
- the embodiment illustrates that even with predominantly laminar flows by appropriate design of the flow channels 6, 7 different flow resistance can be generated.
- the fluid to be cooled is in particular exhaust gas.
- the fluid to be cooled charge air, oil, especially transmission oil, a water-containing cooling liquid, refrigerant of an air conditioner such as CO2.
- the heat exchanger is at least one exhaust gas cooler.
- the heat exchanger is at least one intercooler and / or an oil cooler and / or a coolant radiator and / or a condenser of an air conditioner and / or an evaporator of an air conditioner and / or a gas cooler of an air conditioner.
- the heat exchanger is a combination of at least one exhaust gas cooler and at least one other of the aforementioned heat exchangers.
- the heat exchanger has a flow resistance of the flow path 1, which is between 0.1% and 300%, in particular between 1% and 100%, in particular between 5% and 80%, between 10% and 70%, between 20 % and 60%, between 30% and 50% is above the flow resistance of the flow path 2, preferably only 10% above the flow resistance of the flow path. 2
- the flow resistance of the first flow path 1 is below the flow resistance of the flow path 2.
- Heat exchangers with a deflection region 13 are referred to as U-flow heat exchangers, since the fluid to be cooled flows in a first flow path as far as a deflection section and flows back in a first flow path in the first flow path after deflection in a second flow path substantially in the opposite direction.
