Background technology
Heat exchanger comprises the tube bank of accommodation pipeline in the housing, and forms the flow channel of first fluid and coolant fluid in the space existed between described pipeline and housing.Flow through the outside of pipeline by the second fluid that first fluid cools, walk heat by convective zone, and circulation flows to the inside of the pipeline forming tube bank.
The space of two types is obviously distinguish in this heat exchanger arrangement, the space between the pipeline being namely present in pipeline tube bank and the space between pipeline tube bank with housing.
When heat exchanger has very fine and close pipeline tube bank, be present in the space between housing to pipeline and be present in the ratio in the space between pipeline self relevant with the first coolant fluid stream, this the first coolant fluid stream tends to flow described first space between housing and pipeline, because it has less resistance, thus cooling effectiveness is lowered.
Lacking cooling will cause uncolled region relative to the overheated of other peripheral regions and the high risk therefore causing heat fatigue fault.
In order to reduce the risk of this heat fatigue fault, there is the heat exchanger that some comprise floating nucleome, wherein pipeline tube bank comprises an element in its at least one end, this element allows necessary vertical shift to compensate the different heat expansion between nucleome and housing, makes described expansion not produce stress.
In order to improve cools down efficiency, there are multiple plates of being welded on housing, these plates limit the first coolant fluid and flow through space between housing and pipeline are restrained, make this first fluid converge the space flow through between pipeline.However, these welded plates make to be difficult to be installed in a heat exchanger by floating nucleome, and they can not limit described space completely, because will produce the mechanical interference with nucleome in the case of vibrations depositing, this will terminate to cause structural failure.
Summary of the invention
The present invention proposes the technical scheme solving foregoing problems by means of deflect flow system.
First inventive aspect provides a kind of being suitable for be arranged on the flow deflector as in the heat exchanger of Types Below, this heat exchanger comprises the housing with inner chamber, first coolant fluid is circulated through this inner chamber, and wherein said housing holds the tube bank of at least one pipeline, second fluid to be cooled is circulated through the tube bank of described pipeline, between the wall of the inner chamber of pipeline tube bank and housing, wherein there is the peripheral clearance (perimetralgap) be at least one segment length that pipeline restrains.Deflector according to this first inventive aspect comprises:
-tubular body, it is suitable at least one segment length around pipeline tube bank,
-the first expansion segment, it is disposed in one end of tubular body, makes tubular body extending longitudinally by means of the first expansion segment, wherein:
0 first expansion segment cover circumference be greater than tubular body cover circumference, with reduce pipeline tube bank and housing inner chamber wall between peripheral clearance; And
Zero exists changeover portion between the first expansion segment and tubular body, makes to set up the first coolant fluid circulation restriction, to limit the space between pipeline that the first coolant fluid restrains to pipeline.
If heat exchanger has floating nucleome, then must provide space between the pipeline of pipeline tube bank and the inwall for the housing or inner chamber of installing this pipeline.
In the context of the present invention, the space be present between the pipeline of pipeline tube bank and the inwall of housing is defined as peripheral clearance, and the space limited between the actual pipeline of pipeline tube bank is known as interior space.
If heat exchanger has very fine and close pipeline tube bank, then the ratio between peripheral clearance and interior space is higher.In these cases, first fluid and coolant fluid tend to be circulated through the space providing less resistance, or in other words, the space that the cross section in passageway is larger.When very fine and close pipeline is restrained, first fluid preferably flows through the passage or peripheral clearance that limit between pipeline tube bank and the inwall of housing, the flow of the first fluid being intended to the Ji Nei space, space flow through between the pipeline of pipeline tube bank is reduced, and walks heat by convective zone.
When the heat exchanger that flow deflector is adaptive, described heat exchanger has the peripheral clearance between the pipeline of restraining at inwall and the pipeline of housing at least one segment length of described pipeline.
Described peripheral clearance allows to install the nucleome that floats.However, this peripheral clearance be first fluid generate around pipeline tube bank runner, this runner be different from pipeline tube bank pipeline between runner or interior space, wherein said first fluid must be circulated through described interior space.
Flow deflector of the present invention allows to minimize the first coolant fluid flow through first passage, and this first passage peripheral clearance be through between pipeline tube bank and the inwall of housing is set up.
Be suitable for restriction first fluid through the runner being arranged in peripheral clearance according to the deflector of the first inventive aspect, this flowing is redirected by towards the passage formed by interior space.Therefore, the increase passing through the flow of the passage formed by interior space also causes the increase of speed, decreases stagnant areas also because this reducing the appearance of possible focus.
Flow deflector of the present invention comprises tubular body, multiple pipelines (the preferably all described pipeline tube banks) location that this tubular body is restrained around pipeline.Extend at least one the longitudinal section of the pipeline that this tubular body is restrained at besieged pipeline.
Tubular body limits a perimeter barrier, the cross section of this perimeter barrier can change along its development length, make once fluid is driven to interior space, except the minimum leakage that may occur in the region that such as part is attached to each other, fluid just no longer can arrive/close to (access) peripheral clearance.
In preferred example, flow deflector of the present invention comprises the first expansion segment of the end being positioned at tubular body further.
The circumference that this first expansion segment limits is larger than the maximum circumference limited by tubular body.
Therefore, the position of the peripheral clearance limited between pipeline tube bank and the inwall of housing at the first expansion segment has less area than the length covered along tubular body.
In preferred example, the first expansion segment is oriented to the inwall against housing in case fluid flows through peripheral clearance.Changeover portion between the first expansion segment and tubular body establishes the first coolant fluid and circulates and limit, and makes the first coolant fluid be forced to cycle through interior space.Therefore, the first expansion segment plays the effect of the entrance of the first coolant fluid, and this first coolant fluid is had collected by the region of larger circumference also to be forced to be incorporated in interior space.
Advantageously, first coolant fluid converges in the space between the pipeline being defined in pipeline tube bank by the flow deflector limited in the first inventive aspect, namely which increase the first coolant fluid stream being directed toward pipeline tube bank, described ducted cooling effectiveness is improved.
This means, flow deflector allows heat exchanger to need the cooling agent of small amount, is intended to, with the quantitative proportion of the first coolant fluid of the exterior surface of pipeline, walk heat by convective zone because which increase.Incorporate and use lower first fluid flow to carry out maintaining heat exchanger efficiency permission according to the deflector of the first inventive aspect.In the prior art, the flowing part cycling through peripheral clearance decreases the flowing part cycling through interior space, and in order to compensate the minimizing of discharged heat, must increase total coolant fluid flow.Reason for this reason, this shows likely to reduce first fluid flow compared with the interchanger do not used according to deflector of the present invention.
As extra advantage, due to its be positioned in tubular body pipeline tube bank pipeline on and it is not attached to the fact on housing, deflector of the present invention allows to be used in the heat exchanger with floating nucleome and does not hinder installation.This means, it does not limit the different motion between pipeline that housing and pipeline restrain, and therefore it does not disturb operation or the installation of the nucleome of any type (no matter being floating nucleome or rigidity nucleome).
In certain embodiments, flow deflector has the tubular body comprising the second expansion segment, and this second expansion segment is positioned at the end of the tubular body contrary with the end at the first expansion segment place.
In deflector, there is the second expansion segment export advantageously allowing the orientation of the first coolant fluid.This second expansion segment plays the effect of funnel (funnel), and it allows first fluid to flow out, and prevents its backflow and produces recirculation regions, and preventing arrival from restraining round pipeline the peripheral clearance be present between the inside of housing and tubular body.
In certain embodiments, flow deflector presents the expansion segment of at least one elastically deformable, to guarantee the support of the wall of the inner chamber against housing.
This feature in expansion segment described at least one allows flow deflector to be supported on the inner chamber of housing.Which advantageously reduces pipeline and restrain the vibration suffered, or at least cause the node increasing frequency of natural vibration in vibration mode, reduce the possibility of fatigue damage, this is because the amplitude of nucleome vibration has been reduced.
