There is the heat exchanger of the passage for suppressing liquid motion
Technical field
The present invention relates to a kind of according to claim 1 for indirect heat transfer between the first medium and the second medium Heat exchanger.
Background technology
Such heat exchanger generally has housing and at least one (also referred to as " core "), and this housing limits for receiving first The shell space of the liquid phase of medium, described heat exchanger block has the first heat transfer path for receiving the first medium and is used for receiving Second heat transfer path of the second medium, thus heat can transmit indirectly between two kinds of media, wherein heat exchanger block can with it It is arranged in shell space by the mode of the liquid phase encirclement positioned at the first medium in shell space.
Such a heat exchanger is for example in " The standards of the brazed aluminium plate-fin Heat exchanger manufacturer's association (ALPEMA) ", the third edition, 2010, Fig. 9 of page 67- Shown in 1.This construction of heat exchanger is also referred to as " core shell formula (core-in-shell) " or " block shell-type (block-in- Shell) " heat exchanger.
Preferably being produced by the thermosyphon effect that gasification causes makes the first medium (as cold-producing medium) pass through at least one heat exchanger The driving force of block flowing.However, the shell space of heat exchanger not only executes the purpose of storage tank, and also serve as so that the first matchmaker The steam of generation being situated between and the refrigerant liquid of the first medium or the segregation apparatuss of liquid phase separation.Therefore, in order to related to system The reason, the Free Surface of the liquid phase of the first medium is formed in shell space.In this case, heat exchanger is preferably circle By level and can be vertically provided for longitudinal axis that the housing of cylindrical form relates to or cylinder body axis.In principle, freeze Agent liquid mainly flows upwardly through heat exchanger block.Especially, do not limit fluid (the second medium) to be cooled flows through direction.
If heat exchanger is arranged on mobile base, for example, it is arranged on floating body (such as ship), can have been brought some Liquid in the problem producing with hydraulically full container known, especially container or shell space can move back and forth, from And the multiple positions for example in shell space obtain time dependent liquid level.Thus, for example, heat exchanger block is in the first medium Liquid phase in immersion depth can change, this for example may reduce biography heat availability.Therefore, it is necessary to suppression bath as much as possible (bath) liquid motion is to the degree being able to ensure that safety and reliable operation.
Content of the invention
For this background, the purpose of the present invention therefore that provide a kind of heat exchanger starting mentioned type herein, It can alleviate the problems referred to above.
This problem is solved by the heat exchanger with feature according to claim 1.
It thus provides multiple cylindrical channels for guiding the first medium, described cylindrical channel is in parallel to each other Extend and be especially only dynamically connected with bath or liquid phase stream or bathe or liquid phase can flow through described cylindrical channel, described cylindrical shape Passage is laterally arranged in described shell space with respect at least one heat exchanger block described.
Herein, implication on ordinary meaning for the cylindrical shape is the bottom section of cylinder (in this application for the horizontal stroke of passage Cross section) can have any desired plane domain, it especially can be with circular (cylinder), rectangle, square, triangle Shape or hexagonal mode are formed.In this case, by along not being located in the plane of plane domain and be preferably perpendicular to The straight line of this plane domain or transverse cross-sectional area extension or the longitudinal axis move described plane domain and form corresponding cylinder.

Liquid phase F1 of the first medium M1 rises in the first heat transfer path P of plate type heat exchanger 4,5, and is passed due to indirect Heat and by the second medium M2 partial gasification to be cooled, the second medium M2 is in the second heat transfer path P ' of plate type heat exchanger 4,5 For example it is directed in the way of crossing current (cross-flow) with respect to the first medium M1.The gas phase of consequent first medium M1 G1 can leave in the upper end of plate type heat exchanger 4,5 and discharge from shell space 3 above block 4,5.One of liquid phase F1 Point continue in shell space 3 circulate, this part being previously mentioned in plate type heat exchanger 4,5 in the first heat transfer path P the bottom of from Portion transmits upwards, subsequently flows down to the outside of the plate type heat exchanger 4,5 in shell space 3 again.
Second medium M2 is imported in plate type heat exchanger 4,5, and after flowing through the second distributed heat transfer path P ' with Cooling or liquefied form are discharged from plate type heat exchanger 4,5.
Subsequently, in order to when there is surge movement in housing 2 (longitudinal axis or cylinder body axis fluctuate around vertical curve z) make shell Liquid phase F1 in body space 3 is static, is provided with three units 100 as shown in Figure 1, and each unit has multiple parallel channels 10, Described parallel channels extend respectively along the longitudinal axis L of the longitudinal axis z parallel to housing 2.According to Fig. 2, these passages 10 are preferred Formed, for example, defined circle-cylindrical channel 10 and exist simultaneously by multiple hollow materials 11 being suitably connected to each other Each end of both sides has opening 10a, 10b, and one of opening 10a is disposed generally on upward and along vertical curve z At the height of upper end of corresponding plate type heat exchanger 4,5, and another contrary opening 10b exists respectively down and along vertical curve z The lower section of block 4,5 terminates.Passage 10 is arranged to close to each other preferably along two orthogonal direction in spaces.
Then, Vertical Channel 10 allows liquid phase F1 just leaving corresponding plate type heat exchanger 4,5 in upper end from the first path P again Secondary subsequently enter the first heat transfer path P in the lower end of plate type heat exchanger 4,5 in liquid phase F1 herein to bottom cycle, and due to Thermosyphon effect is attracted again up, thus by partial gasification and cool down the second medium M2.
In this embodiment, Vertical Channel 10 represents the flow resistance in horizontal direction, and therefore suppresses the liquid of the first medium M1 The respective horizontal motion of phase F1, and protect the Verticle circulating by passage 10 being previously mentioned simultaneously.
According to Fig. 1, in unit 100, a unit between two plate type heat exchangers 4,5 is lateral with respect to two blocks 4,5 Ground arrangement.Two other units 100 are arranged in the horizontally adjacent of the periphery wall body 14 of plate type heat exchanger 4,5 and housing 2 Between part or inside region 2a.
Fig. 3 shows the modification of the heat exchanger 1 according to Fig. 1, and it is there is horizontal, longitudinal prolonging with the difference of Fig. 1 The housing 2 stretched, this housing is extended along the longitudinal axis being overlapped with horizontal line or cylinder body axis, that is, vertical with respect to vertical curve z Ground extends.Different from Fig. 1, herein two plate type heat exchangers 4,5 along the longitudinal axis one of housing 2 in another rear ground cloth Put, unit 100 side joint that two blocks 4,5 are each laterally designed by manner described above on both sides, described unit 100 edge The longitudinal axis housing 2 distinguish two blocks of side joint 4,5 on the whole pattern length of two blocks 4,5.
Fig. 4 shows another modification of the heat exchanger 1 according to Fig. 1, and it is passage 10 flatly with the difference of Fig. 1 Extend that is to say, that the longitudinal axis that overlap with vertical curve z with respect to vertical shell 2 extend.Then, the opening of passage 10 Mouth 10a, 10b difference direction in the horizontal direction.According to Fig. 1, unit 100 is arranged with respect to plate type heat exchanger 4,5, two blocks 4, Unit 100 between 5 has the passage 10 with bigger cross-sectional flow area compared to the unit 100 in the outside in block 4,5.Institute Unit 100 is had to protrude past the upper and lower end of plate type heat exchanger 4,5 along vertical curve z, thus when heat exchanger 1 has surge movement When make as much as possible the first medium M1 liquid phase F1 whole filling level remains stationary, according to Fig. 4's in this surge movement The longitudinal axis z of housing 2 changes its gradient, particularly to the outside of paper plane.In this embodiment, existed by liquid phase F1 In horizontal channel, the flow resistance of experience, such as, when flowing back and forth between opening 10a, 10b of passage 10, create static.According to Fig. 4, passage 10 or unit 100 can be formed with the hollow material that multiple cross sections are rectangular or square or by assembling each other or Mutually the plate element of fastening, especially piece (seeing above) are formed.According to Fig. 5, Vertical Channel 10 is not only as the embodiment of Fig. 4 Rectangle is formed as shown on cross section, and can be circle.Other forms are equally contemplated that.In order to Increase the flow resistance in horizontal direction, each horizontal channel 10 can be provided with the additional flow blockage part (obstruction on such as cross section Thing) 12 or be completely enclosed.
