Definitions
- the invention relates to heat exchangers according to the preamble of claim 1 and a device for Perform a cycle.
- Heat exchangers are designed to be as quick and complete as possible Heat transfer between two fluids with different Allow outlet temperatures. To do this the two fluids on both sides of heat-conducting contact surfaces guided. To have the largest possible active contact area to get the fluids mostly through complex channel systems guided. Tube bundle exchangers allow for the Heat exchange efficient ducting, but are very elaborately constructed. Are significantly easier to set up Plate heat exchanger. Plate heat exchangers are now known alternating between plates arranged in parallel Channels for one and the other fluid like this are arranged that similarly complex channel systems, such as arise with tube bundle exchangers. In particular, they are Channels for both fluids designed to last as long as possible and highly structured flow paths arise. The strong structured flow paths lead to undesirably high flow rates Flow resistance.
- a plate heat exchanger is known from WO 95/17272 in which the first channel system is designed such that at least part of the channels as first and second Main channels for at least a first fluid through their entire length substantially along a first and a second main direction.
- the flow resistance is used for pure liquids or gases downsized.
- the phase transitions have been shown in this channel system to reduce the Flow, or to undesirably high flow resistances to lead.
- Individual channel areas at least from one phase of at least one fluid or only poorly flowed, which leads to a reduction in the Heat exchange leads.
- a heat exchanger as an evaporator resulting vapor bubbles in individual channel sections stay behind and the passage of gas and or Hinder liquid.
- Corresponding problems arise when used as a capacitor, the passage hindrance from remaining drops.
- the object of the invention is a simple structure Find heat exchangers that are also in use optimal heat exchange as an evaporator or condenser guaranteed.
- the task is solved by realizing the General term features together with the characteristic features of claim 1 or by the features of the claim 8th.
- the main directions are aligned for the operation that at least one main direction to the vertical one Includes angles that are less than 30 °, in particular is less than 20 °, optionally essentially 0 °. In addition, the angle between the two main directions is less than 60 °. Both main directions are preferably like this orientable that they are between 10 ° and 20 °, preferably both are inclined essentially by 15 ° to the vertical.
- the first two connection areas of the first channels for the first fluid are used in evaporative heat exchangers two opposite circumferential areas of the plates arranged and possibly merge.
- the first two connection areas are in the operating state arranged one above the other and are at least part of the main channels directly connected to each other. Because at least a main direction includes an angle to the vertical, which is less than 30 °, in particular less than 20 °, optionally essentially 0 °, or preferably Is 15 °, the first two connection areas are direct connected by main channels which are in one direction run that is inclined less than 30 ° to the vertical. This ensures a good rise of gas bubbles or at Condensation heat exchangers a good sink of condensed Liquid drops guaranteed.
- the second Channels constructed similar to the first and include third and fourth main channels for the second fluid, which in the run essentially along a main direction.
- the first and second and the third and fourth channels optionally in outer end areas, but preferably connected in all intersection areas.
- the first and second and third and fourth main channels respectively on both sides of a first or second connection level as open half channels formed against the connecting plane.
- the first and second are in the intersection areas or third and fourth main channels in the first or second connection level open to each other so that the first and second channels each as having the main channels sewer networks formed at the junctions in the intersection areas must be considered.
- Plate stack with the described Sewer networks are mutually alternating subsequent first and second plates, being on one side of the first and second plates the fourth or second and on the other the first or third half-channels are formed. All channels one Plate run essentially parallel to each other.
- the second two Connection areas for the second fluid carrying second channels as transverse to the plates preferably through these trending chambers are formed. These two chambers are mutually exclusive only through the second channels connected and completely separated from the first channels.
- the second connection areas are transverse to the bisector spaced apart from each other in the two main directions, so they're not directly through individual Main channels are interconnected. The connection is thus only by at least two interconnected channel sections possible, with at least one channel section in the first and at least one in the second Main direction is aligned.
- this is preferably made up of essentially identical plates or sheets constructed.
- each plate are on both sides in a main direction Grooves arranged.
- the plates as Sheets are formed, they can be provided on both sides Creasing by pressing or punching as beads are formed by a sheet metal side as Depressions and from the other sheet metal side as burr-shaped Protrusions appear.
- To by connecting the plates are two completely separate duct systems to be able to train is along the entire circumference of the plate in a first, the plate on a first Edge bordering, level a first level contact surface intended.
- the plate on the second Bordering the side two contact areas are provided, which are each arranged around a passage opening.
- the Plates or sheets of the heat exchanger also close the same pages or levels. Corresponding Always alternately close contact areas and contact areas to each other and are ever closer to each other connected, especially welded or soldered together.
- the substantially parallel beads or their Longitudinal axes close to a normal plane of the connecting line between the centers of the passage openings an angle that is smaller than 30 °, in particular smaller than 20 °, but is preferably essentially 15 °.
- the beads start from the first level and have theirs on the back protruding ridges in the second Level.
- the depressions between the ridge lines are preferred essentially the same shape as the beads, that means in cross section the parallel beads form one Wavy line, especially with half waves in the form of a Trapezes, the small side of which is rounded.
- To the wettable Do not unnecessarily close the area on either side of the ridge lines reduce, preferably rounding the ridge line a small radius.
- the built up from the plates or sheets described above Plate pack of the heat exchanger is with your two first or second connection areas to first or second connection cables can be connected. Training the Connection areas, the connecting cables and the Connections between these is the particular use customizable.
- connections are preferred designed so that there is a clear separation for both fluids between inflow and outflow or that both through the fluid volume guided through the heat exchanger completely each have to flow a channel system. It can be useful be the two channel systems and their connection areas essentially the same, especially as for the second Described channels to train. If necessary, that is complete flow through a sewer network on a fluid limited and the other fluid forms a bath in which the plate pack with the closed channel system added is. But at least part of the bath fluid must for example as a convection flow Main channels in the plate pack flow around one enough to ensure great heat exchange.
- the first two connection areas are not completely apart train separately. This can make it incomplete separate phase components in the heat exchanger each separate Main parts of the two phases are fed.
- the plate pack is preferably partially in or arranged above a bath area for the first fluid.
- the liquid level is in the working state chosen so that a large part of the plate pack or the first sewer network with the liquid phase of the first fluid is filled. This makes a big one Area of contact area between the two fluids Heating of the fluid to be evaporated used.
- the plate pack essentially completely in the first liquid care must be taken to ensure that the Gas outlet is arranged so that no liquid can escape can, or that escaping liquid from a Separator can be returned to the bathroom.
- the liquid escaping gas can pass through the first and / or second main channels rise into the gas area. Gas that when entering the bath by relaxing or in the bath arises spontaneously, can be from the side of the plate pack climb through the bath into the gas area.
- a particularly compact and effective evaporator or evaporative heat exchanger includes a housing with a side attached refrigerant inlet for the liquid phase of the refrigerant and with one in the highest Housing area over a liquid separator arranged refrigerant outlet for the Gas phase of the refrigerant, as well as a plate pack inlet and outlet connections through the housing for a heat transfer fluid. Is in the operating state the plate pack to a large extent in the liquid Refrigerant phase. Connects to the refrigerant inlet in the housing a relaxation chamber from which the gas escaping during the expansion into the above the liquid ascend the gas area and to the refrigerant outlet can reach.
- the liquid phase can get directly from the relaxation chamber, or via a level chamber in the bathroom area with the Plate pack where the liquid is essentially the first channels filled up to the liquid level.
- the coolant fluid flows through the second channels and loses the heat necessary for the evaporation of the refrigerant.
- the liquid level is chosen so that at least in the working state under the capacitor plate pack lies so that in the plate pack resulting liquid drops through first and / or drain the second main channels down and out of the plate pack can exit. The heat of condensation will through that through the second channels of the capacitor plate pack guided coolant added.
- the relative vertical arrangement of the evaporator and condenser is selected so that the refrigerant level in the evaporator and in the capacitor in the operating state in a desired one Area is relative to the plate packs.
- the capacitor plate pack should essentially lie above the corresponding mirror and the evaporator plate pack for the most part in the liquid phase of the refrigerant. Because of the essentially the same The chiller is built up by the evaporator and condenser easily dimensionable, buildable and adjustable.
- Heat exchangers according to the invention are in any devices to carry out processes with a heat exchange step applicable. Because of the under a small Alignable to the vertical, essentially straight Main channels for a first fluid, can be in these channels both escaping gas and heated liquid one Bath in the sense of a guided convection flow, flow out upwards. The main channels for the first fluid also allow condensate drops to flow out well. By appropriate configurations of the connection areas it is possible to use the first and second channels of each Use accordingly with direct main channels between the connection areas or with connections via at least two differently oriented channel sections to make it usable.
- Fig. 1 illustrates two adjoining plates a heat exchanger plate pack.
- the plates are as circular disk-shaped sheets 1a and 1b with an annular, the outer edge of the contact surface forming the disc 2a, 2b, with two through passage openings 3a, 3b arranged contact areas 4a, 4b and with parallel, formed by beads 5a, 5b, arranged on both sides Main channels formed.
- the beads 5a extend over the entire sheet metal area, which is not a contact area 2a and not designed as a contact area 4a is.
- the beads 5a are shown in the illustration according to FIG. 1 of an upper plate la from a second level - the Drawing plane - in which the contact surface 2a lies, according to above before.
- the beads 5b of a lower plate 1b are from down the same level before, so after the dense Connect the contact surface 2a of the upper plate la with the contact surface 2b of the lower plate 1b one of the Main channels formed second channel system that is only accessible through the passage openings 3a, 3b.
- the axes are the Main channels of the upper and lower sheets 1a, 1b around a first angle of 30 ° to each other.
- the against each other open main channels are in the connection areas 6, in which they face each other, with each other connected.
- the contact areas 4a, 4b face away from one another, so that through the through openings 3a, 3b second fluid in the between the sheets 1a shown and 1b lying second channel system enter or from this can leak.
- the formation of the sheets 1a, 1b and becomes the second channel system formed by the main channels further illustrated by the section shown in FIG. 2.
- Fig. 2 shows a section (II-II, according to Fig. 1) through four sheets 1a, 1b, 1c, 1d.
- the view shown in Fig. 1 is marked in Fig. 2 with B-B, this Level is referred to as the first level 7.
- the one mentioned above second level is between the sheets 1a and 1b 8 and marked between the sheets 1c and 1d with 8 '.
- the sheets 1a and 1b lie with their contact surfaces 2a and 2b in the second level 8.
- the second one Level 8 outgoing beads 5a and 5b extend with their outer ridge lines 9a and 9b, like the contact areas 4a and 4b, up to the first levels 7 and 7 '.
- the Sheet 1b and 1c together become the second channel system tightly closed. That through the passage openings extending second chambers 10 are with the between the two sheets 1a and 1b formed second channels 11 connected and form the second connection areas. Of the main channels of the second go to the connection areas 6 Channel system as half channels in both directions the beads away, what about the hatching is indicated.
- the first channels 12 are between the two sheets 1b and 1c, with analogous to the second channels 11 on both sides of the first level 7 'half-channels in the directions the beads run.
- the first connection areas are arranged between the contact surfaces 2b and 2c. In the Use the plate pack in a bath or as a condenser the division of the ring-shaped first results Connection areas in an inflow and an outflow area by the mode of operation, in particular by the liquid level of the bath or by the fact that Condensate drops only flow out through downward channels can. If necessary, the first connection areas but through tight connections between the Contact areas 2b and 2c delimited, or are analogous to the second chambers 10 are clearly defined first chambers.
- the first channel system 12 is designed that direct channels between the lower and the upper Edge area of the plate pack, or the sheets 1 as the first and second main channels 13 and 14 along their entire length run along a first and a second main direction.
- the fluid level 15 determines which Channels the liquid phase of the first fluid enters and thus also the connection area in which liquid flows.
- the open ends of channels 13 and 14 flow into the connection area in which the gas produced emanates.
- first and / or second channels are only slightly inclined towards the vertical and a direct one Connection between the inflow connection area or Channel area in which gas bubbles arise and the outflow connection area there is a hardly impeded flow 13a and 14a guaranteed by the first fluid.
- Flow with the liquid phase in the intersection areas 6 two in the adjacent first and second Main channels guided partial flows with boundary layer contact across each other, what in both sub-currents leads to a slight turbulence excitation. This will a heated boundary layer adjacent to the channel walls dissolved and the heat transfer between the duct wall and the first fluid improved.
- the two main directions are at an angle of less than 60 °, especially less than 40 °, preferably of essentially 30 ° to each other.
- the main directions can be aligned so that at least one Main direction includes an angle to the vertical that is less than 30 °, in particular less than 20 °.
- channels 14 are essentially as shown in FIG vertically aligned. If necessary, however 3 essentially by 15 ° inclined to the vertical.
- the first and / or the second Main channels ensure in the chosen orientations a good rise of gas bubbles or in condensation heat exchangers a good sinking of condensed liquid drops.
- the second channels have the same structure as the first and include third and fourth main channels 16, 17 for the second fluid, essentially along one each Main direction and at the ends through each other connected contact surfaces 2a, 2b are closed.
- the third and fourth lie in the intersection areas 6 Main channels on both sides of the second connection levels 8, 8 ' open to each other.
- the result is accordingly second channel system constructed in a network. Because the second Connection areas have 10 small dimensions and on one line perpendicular to the main directions are arranged, there are no main channels 16, 17 that the Connect the two connection areas 10 directly to one another.
- the flow paths 18 extend over at least two, but preferably over at least three main channel sections 16, 17 and the crossing areas connecting them 6.
- the second channel system is suitable for a fluid makes no phase transition, especially for a liquid.
- the second fluid must therefore be between the second two Connection areas 10 a long way with strong Make changes of direction. It also gets together partial currents flowing past increase the turbulence, so that the partial flows are well homogenized and heat transfer is optimized. That through the third and fourth main channels 16, 17 formed channel network is independent on the orientation of the plate pack (Fig. 3 and 4 b) advantageous.
- FIG. 5 and 6 show a particularly compact and effective Evaporator or evaporative heat exchanger, which is a housing 20 comprises with a refrigerant inlet opening attached to the side 21 for the liquid phase of the refrigerant and with one in the highest housing area above one Liquid separation device 22 arranged refrigerant outlet opening 23 for the gas phase of the refrigerant, as well as a plate pack 24 with led through the housing 20 Inlet and outlet connections 25 for a heat transfer fluid.
- the plate pack is in the operating state 24 to a large extent in the liquid phase of the Refrigerant.
- a relaxation chamber 26 Connects to the refrigerant inlet opening in the housing 20 21 a relaxation chamber 26 from which gas escaping during expansion via a partition 27 and under a deflecting element 28 through in the over the Liquid gas region 29 flow and from there via lateral guide elements 22a of the separating device 22 can reach the refrigerant outlet opening 23.
- the liquid phase passes from the expansion chamber 26 if necessary, directly or via a level chamber 30, that between a housing wall 20a or the expansion chamber 26 and the partition 27 is formed in one Bath area 31 with the plate pack 24 where the liquid the first channels essentially up to a liquid level 32 replenishes.
- a level chamber 30 that between a housing wall 20a or the expansion chamber 26 and the partition 27 is formed in one Bath area 31 with the plate pack 24 where the liquid the first channels essentially up to a liquid level 32 replenishes.
- two fillers 39 are to be reduced on both sides the plate pack 24 between this and the inner wall of the housing 20 arranged.
- In the deepest part of the housing remains a supply channel 40 through which the Liquid reach the first channels connected in parallel can.
- the coolant fluid flows through the inlet and Outlet connections 25 and through the second channels of Plate pack 24 and thereby loses that for evaporation necessary heat of the refrigerant.
- Fig. 7 shows a refrigerator or heat pump 33, with an evaporative heat exchanger 34 and a condensation heat exchanger 35, both of which are described above Include plate pack.
