Definitions
- the invention relates to a heat exchanger with at least one tube through which a first medium can flow and which is connected at a first end region to a first end element and at its second end region to a second end element.
- a heat exchanger is particularly suitable for use as an exhaust gas heat exchanger, but also for cooling other media.
- Exhaust gas heat exchangers have become known, for example, from DE 196 54 368.
- exhaust gas heat exchangers according to DE 196 54 368 exhaust gas flows through a plurality of tubes. These pipes are surrounded by a pipe jacket through which a coolant flows to cool the exhaust gas.
- an exhaust gas heat exchanger has become known in which a plurality of inner tubes are connected to tube sheets and an outer jacket is connected to them, a coolant being able to flow between the outer jacket and the first tubes.
- Such heat exchangers have the disadvantage that, given the temperature differences between the exhaust gas flowing through the inner tubes and the coolant temperature, the inner tubes exhibit a substantially greater thermal expansion than the outer tube, so that the thermal cycles caused by heating and cooling of the heat exchanger lead to cracks in the Tube sheets comes.
- the object of the invention is to improve exhaust gas heat exchangers according to the prior art in such a way that the heat exchangers are simple and inexpensive to produce and yet there are no cracks over a longer operating time due to different thermal expansions of the inner tubes and the outer jacket.
- this is achieved in an above-mentioned heat exchanger by connecting a first or a second pipe part or a pipe-like part to the first and the second terminating element, the two pipe parts running radially into one another at least over a partial area of their axial extent and with at least one sealing element in the space between the pipe parts.
- At least one chamber is formed between the first tube part and the second tube part. Between means advantageously in the space between the two pipe parts. This can refer to the radial alignment as well as the axial alignment. This chamber expediently serves to accommodate a sealing element. It is also particularly expedient if the at least one chamber is formed by the first tube part and the second tube part.
- the loading boundary of the chamber given by the inner or outer wall of the tube parts and at least one ring-like element.
- the at least one chamber has at least two essentially ring-like, radially protruding elements which are spaced apart in the axial direction.
- a chamber can thereby be defined, which is preferably of annular design.
- the chamber can also be divisible in the circumferential direction by the inclusion or formation of axial webs in ring segments.
- At least one radially projecting element is an integral part of one of the tube parts. It can also be advantageous here if a plurality of ring-like parts is provided, where these are then optionally also connected to a tube part.
- the ring-like protruding elements are formed in one piece with one and / or other tube part.
- At least one ring-like protruding element is an additional component which is arranged between the one and the other tube part and is optionally connected to the one or the other tube part.
- Chamber is at least substantially sealed by the ring-like elements. In another embodiment, it is advantageous if the chamber is essentially not sealed by the ring-like elements. Furthermore, it is expedient if the ring-like protruding elements serve as a support for the tubular parts, viewed in the radial direction. This can advantageously be achieved that the pipe parts do not tilt against each other. It is also expedient if the elements which protrude in the manner of a ring serve as axial bearings. As a result, the two pipe parts can at least slightly shift or move relative to one another, which can be caused by the thermal expansion in the case of temperature differences.
- the chamber is at least partially filled with an elastic means. Furthermore, it is expedient if the chamber is filled in such a way that a ring-like element is formed from the elastic medium in the chamber, which extends between the radially inner and the radially outer tube part. This ring-like element can only be created by filling the medium into a chamber.
- the elastic element can be inserted into a chamber as a ring element.
- the elastic element can be introduced into the chamber as a pasty or gel-like medium.
- the plurality of tubes are each connected to a first end element at their first end region and are connected to the second end element at their second end region. Furthermore, it is expedient if the at least one tube through which a first medium flows is connected at least at one end region to a connecting element for supplying and / or discharging a first medium.
- At least one closure element is connected to at least one connection element for supply and / or discharge from a first medium.
- tubular parts connected to the respective end elements form an essentially dense spatial area with elastic means provided in the chamber, at least two connecting elements being provided and a second medium through which the connecting elements can flow.
