Definitions
- the invention relates to a heat exchanger having at least one tube which can be flowed through by a first medium and which is connected at a first end region to a first closure element and at its second end region to a second closure element.
- a heat exchanger is particularly suitable for use as an exhaust gas heat exchanger, but also for cooling other media.
- Exhaust heat exchangers are for example by the DE 196 54 368 known.
- Exhaust gas flows through a plurality of pipes. These tubes are surrounded by a tube jacket through which a coolant flows to cool the exhaust gas.
- an exhaust gas heat exchanger in which a plurality of inner tubes are connected to tubesheets and with these an outer jacket is connected, wherein between the outer jacket and first tubes, a coolant is flowable.
- Such heat exchangers have the disadvantage that at the temperature differences of the flowing through the inner tubes exhaust gas and the coolant temperature, the inner tubes show a much greater thermal expansion than the outer tube, so that by the thermal cycles by warming and cooling of the heat exchanger to crack in the Tube sheets comes.
- the object of the invention is to improve exhaust gas heat exchanger according to the prior art such that the heat exchangers are simple and inexpensive to manufacture and yet it does not come to cracks due to different thermal expansion of the inner tubes and the outer jacket over a longer period of operation.
