Definitions
- the invention relates to an exhaust gas cooling module for an internal combustion engine with a valve having a valve housing, a valve body arranged in the valve body, which dominates an exhaust gas recirculation channel, and an actuator for actuating the valve body, and an exhaust gas heat exchanger, which is connected to the valve housing, wherein in the valve housing at least one coolant channel is formed, which is fluidically connected to a coolant channel of the exhaust gas heat exchanger.
- a module is off EP 1 363 013 A1 , and corresponds to the subject matter of the preamble of claim 1.
- Such exhaust gas cooling modules are known. For pollutant reduction, an exhaust gas flow is regulated fed to an exhaust gas cooler. To reduce the interfaces that have been made over the past years via hose or pipe connections between the individual units, modules have been developed, which were attached via simple flange connections to each other in a current-carrying manner.
- the housing of an exhaust gas recirculation valve is connected directly to a heat exchanger.
- This also has the advantage that an exhaust gas recirculation valve arranged upstream of the heat exchanger, that is to say in the hot region of the exhaust gas recirculation line, can be fluidically connected to the coolant jacket of the heat exchanger in order to prevent overheating of the actuator by the hot exhaust gas by means of thermal separation.
- Such a module is for example from the DE 103 21 637 A1 known.
- a combined exhaust gas recirculation and bypass valve is connected via a flange to an exhaust gas cooler, which can be bypassed via a bypass passage, which is also in the housing of the Heat exchanger is arranged.
- the heat exchanger has an inner housing and an outer housing surrounding the inner housing, between which a coolant jacket is formed.
- the coolant jacket is connected via the flange to a coolant channel, which is formed in the valve housing and thermally separates the actuator from the exhaust gas flow channel.
- a coolant inlet is formed, via which the coolant flows into the coolant jacket. From the coolant jacket, the coolant flows into the coolant channel of the valve housing, on which a coolant outlet is formed, via which the coolant flows out again.
- the object of the invention is therefore to ensure a flow through the connected to a coolant passage of the heat exchanger coolant passage of the valve housing even with formation of the coolant inlet and the coolant outlet on the heat exchanger. It should be possible to dispense with additional components and it should cost materials for the valve can be used.
- the exhaust gas heat exchanger has a coolant inlet and a coolant outlet, wherein a coolant inlet of the valve housing via a first connecting channel fluidly with the coolant inlet the exhaust gas heat exchanger is connected and a coolant outlet of the valve housing is connected via a second connecting channel with the coolant outlet, the pressure drop of the coolant circuit is transmitted to the inlet and outlet of the valve housing, thus ensuring a flow of the coolant in the coolant passage of the valve housing. By ensuring flow, low-cost materials for the valve can be used as more heat is removed.
- the first connection channel is connected via the coolant channel of the exhaust gas heat exchanger with the coolant inlet, wherein the mouth of the first connection channel is arranged in the coolant channel closer to the coolant inlet than to the coolant outlet.
- the amount of coolant guided into the coolant jacket of the heat exchanger remains controllable.
- the first connection channel opens in the coolant inlet of the exhaust gas heat exchanger. So there is an equality of the temperature level at the heat exchanger and the valve housing. It can be used for the flow through the valve housing, the entire pressure difference, which rests on the heat exchanger.
- the second connecting channel opens in the coolant outlet of the exhaust gas heat exchanger, in order to avoid vortex formation in the coolant jacket by an inflow of two sides and a flow resistance rising thereby.
- the mouth of the first connection channel is arranged on the side opposite the coolant inlet and coolant outlet side of the exhaust gas heat exchanger, whereby short-circuit currents between the inlet of the first connection channel and the outlet of the second connection channel are avoided and thus a sufficient Flow through the coolant channel is ensured in the valve housing.
- connection channels can be formed as straight tubes.
- the connecting channels are formed in an outer casing of the exhaust gas heat exchanger.
- Such an outer housing can be produced in particular by sand casting.
- the exhaust gas heat exchanger with the valve housing and the connecting channels are connected to the coolant inlet and the coolant outlet of the valve housing via a flange with the interposition of a seal. This creates a simple and sealed way of connecting the two coolant-carrying housing parts.
- a cooling module in which a flow through a coolant channel in the connected valve housing is ensured even when an inlet and outlet is formed on the outer housing of the cooling module.
- Such a module is easy to assemble and manufacture.
- the valve can be reliably cooled directly in the area which has the highest thermal load, so that a thermal overload of the actuator is avoided.
- the number of existing interfaces is minimized.
- the illustrated exhaust gas cooling module consists of three housing parts, of which a first housing part is a valve housing 2, a second housing part is an outer housing 4 of an exhaust gas heat exchanger 6 and a third housing part is an inner housing 8 of the exhaust gas heat exchanger 6.
- the valve housing 2 is the channel-forming housing of an exhaust gas recirculation valve 10, which in the present embodiment has two exhaust gas recirculation flaps 12, 14 as a valve body, which each dominate a flow cross-section, each flow cross-section is associated with an exhaust duct 16, 18.
- the first exhaust passage 16 is separated from the second exhaust passage 18 by a partition wall 20 formed in the valve housing 2.
- This partition 20 extends from the inlet 22 of the exhaust gas cooling module to the outlet 24 of the valve housing 2, which is arranged offset by 90 ° to the inlet 22, so that an exhaust gas flow in the interior of the valve housing 2 is deflected by 90 °.
- the inlet 22 is designed as a flange, via which the module can be flanged directly to an exhaust manifold, not shown, or an engine block.
- the exhaust gas recirculation flaps 12, 14 are arranged on a common shaft 26, which is mounted in the valve housing 2 and is rotatable by means of an electromotive actuator 28 via a coupling linkage 30.
- the shaft 26 is surrounded outside of the valve housing 2 by a return spring 32, via which the exhaust gas recirculation flaps 12, 14 are rotated in their closing the two exhaust channels 16, 18 position in case of failure of the actuator.
- coolant channels 34 are additionally formed, via which the thermally highly stressed valve housing 2 is cooled and in particular the actuator 28 is protected against thermal overload becomes.
- the valve housing 2 assumes the function of a precooler.
- the thermal shield between the actuator 28 and the exhaust gas leading channels 16, 18 through the interposed cooling channels 34.
- the valve housing 2 is attached via a flange 38 to the exhaust gas heat exchanger 6 with the interposition of a seal, not shown.
- the inner housing 8 is arranged, in which also a partition 40 is formed, which is arranged in extension of the partition wall 20 of the valve housing 2, so that a separation of the two exhaust channels 20, 22 and in the heat exchanger 6 continues.
- the inner housing 8 has at its axial ends extensions 42, the outer diameter of which corresponds to the inner diameter of the outer housing 4, so that a coolant channel 44 forming coolant jacket between the inner housing 8 and the outer housing 4 is tightly defined with the interposition of a radial seal.
- the fluid connection between the coolant channels 34 of the valve housing 2 and the coolant channel 44 of the heat exchanger 6 is also produced via the flange connection.
- a pressure difference of the cooling circuit of the internal combustion engine is used according to the invention by a coolant inlet 46 is connected in the valve housing 2 with a first connection channel 48, which opens in the vicinity of a coolant inlet 50 of the coolant channel 44 and a coolant outlet 52 is connected from the valve housing 2 via a second connecting channel 54 with a coolant outlet 56 of the coolant channel 44 of the exhaust gas heat exchanger 6.
- the two connection channels 48, 54 are formed separately in the outer housing 4 of the heat exchanger 6 and are arranged opposite to each other with respect to the central axis of the heat exchanger 6. As a result, short-circuit currents between the two connection channels 48, 54 are largely prevented.
- the connecting channels 48, 54 can be made straight, so that they can be produced directly in sand casting and no additional components must be used.
- the coolant flowing through the inlet 50 into the coolant jacket 44 flows around the inner housing 8, wherein a portion of the coolant through the pressure difference corresponding to the pump power of a connected coolant pump between the two connecting channels 48, 54 from the coolant jacket 44 via an orifice 58 in the first connection channel 48 is sucked. From here, the coolant flows via the coolant inlet 46 into the valve housing 2 and through the coolant channels 34 and the coolant tubes 36 to the coolant outlet 52 and further via the connecting channel 54 directly to the coolant outlet 56. Between the two connecting channels is thus approximately the same driving Pressure gradient as between the coolant inlet 50 and the coolant outlet 56 of the heat exchanger. 6
- valve housing 2 a flow through the valve housing 2 is ensured with coolant in a simple manner. This serves to protect the actuator 28 against excessive thermal load and increases the total cooling capacity of the entire module.
- Additional pollutant reduction by such a module can also be achieved in that within the coolant channel 44 or in the inlet or outlet of the coolant channel 44, a coolant valve is arranged, via which the flow cross-section of the coolant channel 34, 44 can be interrupted.
- a coolant valve is arranged, via which the flow cross-section of the coolant channel 34, 44 can be interrupted.
- connections between the connecting lines and the coolant inlet and outlet do not have to be exactly as described.
- a use of the pressure gradient can be done either via the coolant channel of the heat exchanger or directly via the inlet and the outlet.
- the production and structural design of the housing parts can be modified depending on the application.
- an exhaust gas recirculation valve for example, a lift valve can be used.
- bypass valves can be cooled in the same way.
