Definitions
- the invention relates to a heat exchanger, in particular an exhaust gas heat exchanger, according to the preamble of claim 1 and a method for operating an exhaust system according to claim 10,
- Heat exchangers which are used as exhaust heat exchanger or exhaust gas cooler in the exhaust gas recirculation in motor vehicles are known in various designs, for example by the DE 199 07 163 C2 the applicant.
- a heat exchanger in particular Abgas139ubertrager for a motor vehicle provided with exhaust gas and cooled by a fluid channels, the heat exchanger having a first partial heat exchanger and at least a second partial heat exchanger, the second partial heat exchanger having means which are formed to dehumidify the exhaust gas.
- the second partial heat exchanger it is possible, on the one hand, for the second partial heat exchanger to be arranged below the first partial heat exchanger or, alternatively, for the first and second partial heat exchangers to be arranged concentrically, the second partial heat exchanger being arranged outside the first partial heat exchanger.
- the first and second partial heat exchanger is arranged as a structural unit in a common housing.
- the second Operafigurationüberirager could also be arranged as a bypass channel outside the housing.
- first partial heat exchanger is embodied with channels through which exhaust gas can flow and which can be cooled by a fluid.
- the first partial heat exchanger is thus designed as a conventional Abgas139ubertrager of the prior art, while the second has a means which is designed to dehumidify the exhaust gas.
- This agent is preferably a sorbent, for example zeolite, which fills the second Tell139übertrager partially or intelligently.
- the sorbent is arranged concentrically on the inner wall of the second Operanceübertragers and connected thereto.
- the second partial heat exchanger is electrically heated, so that if necessary, the means for dehumidification can be baked out.
- the heat exchanger further comprises a flap, so that the exhaust gas flow into a first partial flow in the first partial heat exchanger and a second partial flow in the second partial heat exchanger can be divided.
- the flap By means of the flap, the individual partial flows can thus be specifically controlled and / or regulated.
- the second partial heat exchanger has a drain for separating the condensate from the exhaust gas.
- Such a heat exchanger can be used in particular in an exhaust system of a motor vehicle in order to dehumidify the exhaust gas flow.
- Fig. 1 time designed as a Abgastownauertraser 1 heat exchanger, as used for example in the exhaust gas recirculation for motor vehicles.
- the exhaust gas 2 flows through an inlet 11 into the heat exchanger and leaves it through an outlet 12.
- the cooling of the exhaust gas is effected by a fluid 3, preferably a coolant, which can be taken from a cooling circuit (not shown) of the internal combustion engine of the motor vehicle.
- the coolant flows through an inlet 13 into the heat exchanger, exchanges heat with the exhaust gas and leaves the heat exchanger through an outlet 14,
- the exhaust gas heat exchanger 1 has a housing shell 16 and is divided in its interior into a first partial heat exchanger 4 and a second partial heat exchanger 5. Not shown in this embodiment channels, in the form of exhaust pipes. These exhaust pipes, that is, pipes through which exhaust gas can flow, are arranged such that gaps exist between them, through which the coolant 3 can flow,
- the exhaust pipes are arranged only in the first partial heat exchanger 4.
- a sorbent 6 which is adapted to dehumidify the exhaust gas flowing into the second partial heat exchanger 5 (second partial flow 9).
- the sorbent for example zeolite, is arranged on the inner wall of the second Partisseübertragers.
- a flap 7 Downstream of the inlet 11 of the exhaust gas heat exchanger 1, a flap 7 is arranged, which regulates the exhaust gas stream 2 in the first (first partial flow 8) and second (second partial flow 9) partial heat exchanger.
