Coiled heat exchanger is known with its big interior elasticity.By forming helical spring pipe, these coiled heat exchanger elasticity are very big, and particularly are suitable for compensating the stress that is caused by thermal expansion or contraction, thereby allow extra high operational reliability.
Summary of the invention
The objective of the invention is to, further improve the reliability of coiled heat exchanger.
This purpose solves in the following manner, promptly uses at least one adiabatic elastomeric element, this elastomeric element to be arranged on the radially outer of the inside of described shell and bundle in coiled heat exchanger and has metal material.
It is believed that up to now, the intrinsic elasticity of the pipe of coiling, in case of necessity with the Guan Zaiqi end on elastic bearing explicitly, give coiled heat exchanger a kind of remarkable ability that is used to compensate thermal stress, make on this direction, to need not other measures.But clearly propose within the scope of the invention, even the reliability when thermal stress also can reduce operation in coiled heat exchanger.Now, the present invention does not adopt the parameter of the change of the intrinsic flexible raising of common parameter, for example pipe or tube end supporting, but the adiabatic parts that are in the radially outer of described bundle by use solve above-mentioned purpose.Thus, not only can compensate the stress that occurs owing to temperature change, but and the whole bundle of balance with respect to bigger the steady state temperature difference and the thermograde of exocoel or inner chamber.
At this, " not conducting heat " is meant a kind of like this parts, and its surface is in operation and does not directly contact with such two fluids: the heat transfer of wanting between these two fluids.Certainly, each parts all has the heat transfer effect that causes by heat conduction.This is not excluded in the notion of described " not conducting heat ".
At this, " bundle " is meant the geometric space of hollow cylinder form, and its cylindrosymmetric section by the pipe winding forms.It comprises pipe spiral wound section and extend to a cylinder side face in inside always
This cylinder side face contacts the pipe inboard---and not comprising core pipe itself---of penetralia pipe layer and outwards extends to a cylinder side face always, the pipe outside of this cylinder side face contact extreme outer duct layer.If between described shell and outermost pipe layer, a lining (Hemd) is set, should " bundle " no longer comprise this lining so.
When parts at least in part the radially outer of the hollow cylinder that constitutes by this bundle, promptly between outermost pipe layer and shell or inner most pipe layer and core pipe between one of space in or be positioned at this core pipe when inner, think that then these parts are arranged on " radially outer of bundle ".Those only be arranged on the top of axial end portion of described bundle or below parts, promptly for example those parts that are used for the support column end are not arranged on " radially outer of bundle ".This elastomeric element on the meaning of the present invention for example can be arranged on (referring to German patent application 102006033697 and relative application) between two concentric tube banks, be arranged between outermost pipe layer and the described lining or be arranged between inner most pipe layer and the core pipe.
At this, when rigidity that the rigidity (elastic constant) of parts less than heat transfer component, is particularly managed and restrained, it is " flexible " that these parts are called.The elastic constant of this or these " adiabatic elastomeric element " particularly less than tube bank 80%, preferably less than 50%, less than 10% or less than 1%.It is arranged and elasticity is so constructed, and makes when heat exchanger moves the thermal stress that causes owing to thermal expansion in the pipe keep below the limit of stretch of these pipes, particularly is lower than 2/3rds of this limit of stretch, be preferably lower than these pipes limit of stretch 5%.
Described adiabatic elastomeric element has metal material, that is to say, it is made of one or more metal materials at least in part.
In the present invention, preferably use a plurality of radially outer, adiabatic elastomeric elements at described bundle.
This or these adiabatic elastomeric element is preferably sealed with parts, particularly at least one shape with these pipes of a heat transfer, force closure or be slidingly connected.This connection for example can directly produce by welding or soldering, but also can produce by one or more plug-in units that have than low elasticity.These flexible parts for example can be connected on one or more pipes by one or more contact pin.Alternatively, this adiabatic elastomeric element also can be a part or the moulding section (Anformteil) of a heat transfer component.
" contact pin " is stiff parts and directly contacts at least two contacts site with at least one pipe, and these contacts site are arranged on the adjacent on circle of same pipe usually.On these positions, the connection between contact pin and the pipe is that shape is sealed and particularly by groove formation suitable in the contact pin, this groove for example roughly has the shape of cylindrical sleeve sector.
Alternatively, preferably additionally, this or these adiabatic parts can be sealed with adiabatic parts shape, force closure or be slidingly connected.For example these resilient parts can be connected with one or more pipe force closures ground on a side and be connected with described shell force closure ground on opposite side.Thus, for example will realize tube bank be a side and shell be the opposing party hot length change take off connection.
But the connection of the sealed or force closure of the shape on a described side also is possible with the combination that is slidingly connected on described opposite side.
Be typically provided with a bigger annular gap between vessel shell externally and the outermost pipe layer.Flow through this gap rather than the intermediate space between these pipes of flowing through of the part of the fluid of described exocoel if flow through, this part does not participate in or only participates on not half in the heat exchange with described another fluid so, the inside of described another fluid flowing pipe.Therefore, common is that a lining is set between outermost pipe layer and shell.In the case advantageously, described adiabatic elastomeric element and this lining force closure or be slidingly connected.
Particularly when described adiabatic elastomeric element is connected with one or more pipes, thereby realized the reduction of the stress that takes off connection and realized causing that these Guan Weiyi sides and described lining change for the opposing party's hot diameter by heat on described opposite side.
When these heat transfer components, particularly these pipes have greater than 8*10
-61/K, particularly greater than 16.1*10
-61/K, particularly greater than 20*10
-6During the thermal coefficient of expansion of 1/K, the present invention is employed with particularly can having advantage.Tube material for example can constitute by stainless steel, particularly V2A or by aluminium or aluminium alloy.
Advantageously, described elastomeric element has the spring effect at least two opposite directions.Be that it not only flexibly is configured to pulling load, and be configured to press load.Preferably this elastomeric element has the spring effect on all directions.
Advantageously, along at least two of the axis settings of described bundle, particularly at least four adiabatic elastomeric elements.Can be implemented in thus on the whole height of described bundle or axially stretch very most of on elasticity connect.Position with the axial arranged elastomeric element of difference can have identical or different location components (Ortskomponenten), promptly can directly in its axial order (Abfolge) be provided with stackedly or each other with staggering at (circumferencial direction) on the tangential direction.
Additionally or alternatively advantageously, along at least two of the circumference settings of described bundle, particularly at least four adiabatic elastomeric elements.Can be implemented in thus on the whole circumference of described bundle or the elasticity on this circumference very most of connects.Position with elastomeric element of different tangential location components can have identical or different location components, promptly can be arranged on the circumference with identical or different height (highly) on the axis direction.
