Definitions
- the invention relates to a wound heat exchanger having a plurality of tubes wound around a core tube with a jacket defining an outer space around the tubes.
- wound heat exchangers In LNG baseload plants, natural gas is continuously liquefied in large quantities. The liquefaction of the natural gas is usually carried out by heat exchange with a refrigerant in wound heat exchangers. But there are also other applications of wound heat exchangers known, both at temperatures below ambient temperature to the lowest temperatures and at high temperatures up to well above ambient temperature. In principle, wound heat exchangers can be used at any temperature for which their material is suitable.
- a wound heat exchanger In a wound heat exchanger several layers of tubes are wound onto a core tube. Through the individual tubes a medium is passed, which occurs in heat exchange with a flowing in the space between the tubes and a surrounding jacket medium. The tubes are combined at the top and bottom end of the heat exchanger in one or more groups.
- Coiled heat exchangers are known for their high internal elasticity. By shaped as a spiral spring tubes they are very elastic in itself, as particularly suitable to compensate for induced by thermal expansion or contraction stresses and thus to allow a particularly high level of operational safety.
- the invention is therefore based on the object to further increase the reliability of a wound heat exchanger.
- This object is achieved in that at least one non-heat-transmitting elastic component is used in the interior of the heat exchanger.
- the intrinsic elasticity of the wound tubes possibly in conjunction with elastic support of the tubes at their ends, provides a coiled heat exchanger with such superior thermal stress compensation capability that further action in this direction is unnecessary.
- thermal stresses can reduce reliability during operation.
- the invention does not start with the usual parameters, for example, an increase in the inherent elasticity of the tubes or a change in the storage of pipe ends, but solves the above object by the use of non-heat-transmitting components in the interior of the heat exchanger.
- non-heat transferring is here understood a component whose surfaces are not in direct contact with the two fluids during operation, between which the intended heat transfer takes place. Of course, every component has a heat transfer effect by heat conduction. This is not excluded in the term “non-heat transferring”.
- a component is arranged when it is inside the outer shell and not at the pipe ends. Components that serve to support the pipe ends are therefore excluded. Such a component may be, for example, in the outer space of the wound heat exchanger, but in principle also in the interior of a pipe.
- a component is referred to herein as “elastic” when its spring stiffness (spring constant) is less than that of the heat-transmitting components, in particular the tubes and the tube bundle.
- the spring constant of the or the “non-heat-transmitting elastic components” is in particular less than 80%, preferably less than 50%, less than 10% or less than 1% of the tube bundle.
- a plurality of non-heat-transmitting elastic components are used in the interior of the heat exchanger.
- the one or more non-heat-transmitting elastic components are preferably connected to a heat-transmitting component, in particular at least one of the tubes, positively, non-positively or slidably.
- the connection can be made directly, for example by welding or soldering, or via one or more intermediate pieces, which have a lower elasticity.
- the non-heat-transmitting elastic component may also be a part or molded part of a heat-transmitting component.
- the one or more non-heat-transmitting elastic components may be connected to a non-heat-transmitting component form-fitting, non-positive or sliding.
- the resilient elements may be connected non-positively to one side with one or more tubes and on the other side with the jacket.
- the invention is particularly advantageous when the heat-transferring components, in particular the tubes, have a thermal expansion coefficient greater than 8 ⁇ 10 -6 1 / K, in particular greater than 16.1 ⁇ 10 -6 1 / K, in particular greater than 20 ⁇ 10 -6 1 / K.
- the pipe material may for example consist of stainless steel, in particular V2A, or of aluminum or an aluminum alloy.
- the non-heat-transmitting elastic components 1a, 1b are non-positively connected on one side (bottom in FIG. 1) via a first intermediate piece 2 to heat-transmitting components such as pipes (not shown), for example by a joint connection.
- the non-heat-transferring elastic components 1a, 1b are frictionally connected via a second intermediate piece 3 to a non-heat-transferring component, such as a shirt, which is disposed between the outermost sheet layer and the jacket of the wound heat exchanger.
- a non-heat-transferring component such as a shirt
- FIG. 2 shows a similar exemplary embodiment which, analogously to FIG. 1, has two non-heat-transmitting elastic components 1a, 1b and a first and a second intermediate piece 2, 3.
- the first intermediate piece 2 is non-positively connected to the tubes of the outermost layer of pipe 4, for example by a welded connection.
- the second intermediate piece 2 is non-positively connected to a shirt 5, for example by a welded connection.
- the construction of the components 1a, 1b, 2, 3 is repeated at further points (for example 6), preferably at regular intervals.
- an elastic, non-heat-transmitting component for the degradation of thermally induced stress also be used in all other types of heat exchangers, for example in U-tube exchangers, pipe exchangers or plate heat exchangers.
