Definitions
- the invention relates to a heat transfer unit for internal combustion engines with a housing in which at least a first channel through which a fluid to be cooled is arranged, at least one channel through which a second fluid can pass and at least one channel through which a coolant can pass, and a heat transfer unit for the oil circuit of an internal combustion engine with an oil-permeable channel and at least one channel through which a coolant can flow, wherein the oil-permeable channel is in heat-conducting contact with the channel through which the coolant can flow.
- Such combined heat transfer units are known from the prior art and are used, for example, to cool in a unit both the charge air and an exhaust gas flow, or to arrange, for example, a lubricating oil cooling either individually or in a housing with a charge air cooling or exhaust gas cooling.
- a lubricating oil cooling either individually or in a housing with a charge air cooling or exhaust gas cooling.
- DE 102 03 003 A1 discloses an exhaust gas heat exchanger having in a housing both the exhaust gas cooling device and a bypass device bypassing the cooling device. Depending on the operating state of the internal combustion engine, the exhaust gas flow is conducted either through the cooling device or via the bypass channel via an upstream bypass flap.
- the object of the invention is therefore to provide a heat transfer unit with which an effective temperature management can be operated in the internal combustion engine, at the same time the space requirement should be minimized.
- the oil circuit of an internal combustion engine is to be completely dispensed with the heater currently used in turbo diesel engines. This should be further reduced in comparison to known embodiments, the high pollutant content generating warm-up phase.
- a bypass channel for the first fluid to be cooled is formed, via which the at least one first channel through which the first fluid to be cooled can be bypassed.
- this object is achieved in that in the heat transfer unit an exhaust gas flow-through channel is formed, which is also in heat conductive contact to the oil flow channel, so that rapid heating of the oil through the warm exhaust gas flow is reached.
- the exhaust gas through-flowable channel is a bypass channel of an exhaust gas cooler.
- the at least one channel through which the second fluid can flow is arranged between the bypass channel and the channel which can be flowed through by the coolant. This ensures that depending on the flow through the bypass channel and the coolant flow-through channel, the second fluid can either be heated or cooled either.
- the fluid mass flow of the first fluid to be cooled in the bypass channel and the first channel through which the first fluid to be cooled can be controlled via at least one control device.
- temperature control of both the first fluid to be cooled and the second fluid becomes possible.
- valves may be formed, for example, flap-shaped and electromotive Adjustment units are dependent or independently regulated. A temperature control is thus easily possible.
- the channel through which the coolant can flow has a first common partition wall with the channel through which the first fluid to be cooled flows and a second common partition wall with the channel through which the second fluid can flow.
- the two common partitions thus serve directly as thermal bridges between the media.
- the channel through which the coolant can flow completely surrounds the channel through which the first fluid to be cooled can flow. This ensures optimized cooling of the first fluid to be cooled.
- ribs protrude into at least one of the channels of at least one of the partitions. These also significantly improve the heat transfer between the media. In particular, with formation of the ribs in the gas-conducting channels, this results in great advantages in terms of heat transfer. Both continuous ribs along the flow direction are conceivable as well as interrupted single ribs.
- the coolant flow is controllable via a control device, so that it can be completely exhibited during the warm-up phase, whereby a much faster heating of the second fluid can be achieved.
- This advantage can also be enhanced by additionally controlling the fluid mass flow of the second fluid via a control direction.
- the first fluid to be cooled is exhaust and the second fluid is oil.
- the exhaust gas flow through channel is bypassed and the exhaust gas flowing through the bypass channel can be used for faster heating of the oil in the combined heat transfer unit.
- the coolant can be used both for cooling the exhaust gas and for cooling the oil in the heat transfer unit.
- the heat transfer unit is produced from die-cast parts which are connected to one another by friction stir welding.
- the heat transfer unit can be at least partially integrated into the cylinder head.
- FIGS. 1 and 2 For better understanding, the exemplary embodiment according to FIGS. 1 and 2 is explained with reference to an exemplary embodiment in which exhaust gas is used as the first fluid to be cooled and as second fluid oil, so that the heat transfer unit is a combined exhaust / oil heat transfer unit ,
- the heat transfer unit is a combined exhaust / oil heat transfer unit
- such a heat transfer unit can also be used for other cooling combinations.
- the heat transfer unit consists of a housing 1 which surrounds the heat transfer unit and defines it to the outside, which housing can be designed in one or more parts.
- a first through-flow of exhaust gas channel 2 is formed in the housing 1, which passage 2 can be traversed by a coolant-flow channel 4, wherein the coolant flow-through channel 4 is designed such that it completely surrounds the exhaust gas flow channel 2 in cross section ,
- a bypass channel 5 is arranged, which is also flowed through by exhaust gas.
- the individual channels 2, 3, 4, 5 are each separated from each other via common partitions, so that a first common partition 6 between the coolant flow-through channel 4 and the exhaust gas permeable channel 2 is arranged, a second common partition 7 between the coolant flow channel 4 and the oil-permeable channel 3 is arranged and a third common partition wall 8 between the bypass channel 5 and the oil-flow channel 3 is arranged.
- ribs 9 protrude in the present embodiment, both in the bypass channel 5 and in the oil-flowed channel 3 and the exhaust gas flowed through channel 2, both in the exhaust gas flowed through channel 2 as well as in the oil flow channel 3 protrude the ribs of two opposite sides , This means for the exhaust gas-permeable channel 2 a significant improvement in the heat transfer, as is significantly improved on the two-sided ribbing of the heat transfer through the surrounding coolant.
- the ribbing means that both the heat transfer from the coolant to the oil is improved by the ribs 9 formed on the dividing wall 7 and the heat transfer by the ribs 9 formed on the dividing wall 8 can be improved by the bypass duct 5 ,
- the coolant flow-through channel 4 has an inlet connection shown in FIG. 1, which in the present exemplary embodiment is arranged laterally in the front region of the heat transfer unit and via which the coolant flows through the channel 4 which can flow through the coolant.
- a corresponding unillustrated coolant outlet pipe is present in the rear region of the heat exchanger unit.
- a coolant regulating device 11 is additionally designed in the form of a control valve, via which the coolant flow can be controlled.
- the oil flow-through channel 3 has in the present example, a laterally arranged oil inlet nozzle 12, in turn, on the opposite side, ie in the rear region of the oil-permeable channel 3, a corresponding outlet nozzle is arranged.
- a control device 13 for controlling the flow rate of the oil in the form of a control valve is arranged.
- FIG. 2 shows the inlet region in the form of an exhaust gas inlet nozzle 14 for the heat transfer unit.
- a first control device 15 in the form of a flap valve and a second control device 16 in the form of a flap valve are formed in the area of the exhaust inlet connection 14. These are arranged in each case in that the exhaust gas flow-through channel 2 can be closed by the first flap 15 and the second bypass channel 5, also through which exhaust gas can flow, through the second flap 16.
- These two flaps 15, 16 can be regulated either independently or independently of each other, depending on whether only a temperature control or an exhaust quantity control is to be realized.
- the oil flow-through channel is closed at its end facing the exhaust gas inlet port 14 by a wall 17.
- the partition 6 and the housing 1 serve as abutment surfaces for the flap 15 to the closure of the channel 2 and the wall 17 and the housing 1 as abutment surfaces for the flap 16 for closing the bypass channel. 5
- a suitably trained exhaust outlet not shown is arranged on the opposite in the flow direction of the exhaust gas side of the heat transfer unit, but without flaps, and it would also be possible to arrange the flaps 15, 16 at corresponding positions on the outlet nozzle.
- the exhaust duct 2 can be bypassed by closing the control device 15, so that in this phase, the flap 16 is in the open position and hot exhaust can flow through the bypass channel 5 uncooled.
- the control valve 11 is preferably closed, so that no coolant flows through the heat transfer unit and thus takes place only a heating of the oil whose volume flow in this phase by means of the Regulating device 13 can be regulated.
- the flap 16 can be closed and the flap 15 can be opened, so that now the exhaust gas flow is reduced to reduce the nitrogen oxides formed during combustion via the exhaust duct 2 and no more exhaust gas passes into the bypass channel 5.
- the control valve 11 is opened, so that the exhaust gas channel 2 is now flowing around coolant and the oil passage 3 receives a heat-conducting contact via the partition wall 7 to the coolant channel 4.
- a heat transfer unit can be created in which only the oil-traversable channel is cooled by both coolant and heated by the exhaust gas.
- changes in the designs of the flow-through channels, for example in the form of plate or tube bundles are of course also conceivable as a different positioning of the input and output nozzle.
