Description
Technical field
The present invention relates to a kind of method that is used to make adsorption heat exchanger, particularly a kind of method that is used to make the adsorption heat exchanger that comprises heat exchanger structure, this heat exchanger structure is filled with synthetic in advance solid absorbing material.
Background technology
Adsorption heat exchanger comprises heat exchanger structure, and this heat exchanger structure is used for input and output heat energy and it becomes thermo-contact with absorbing material, and this absorbing material uses the phase transformation of working media (so-called absorbate) so that the potential heat energy of combination and release.If the working media by the condensed steam shape comes release heat like this, otherwise also can use heat energy to evaporate absorbate again by the heat exchanger structure input.For the phase transformation of carrying out absorbate will be used most solid material (so-called absorption material).This absorbing material is characterised in that it has the open porous structure of big area-volume ratio.Typically, the surface size of absorbing material can reach several 100m
2The absorbing material of/g.Internal cavities in these materials has the dimension of molecular size.Realize the effect of absorbing material thus, be about to foreign atom or foreign molecules and receive in the structure of its microcosmic porous, and carry out the transition to the associated state from gas phase.The absorbing material that for example uses in adsorption heat exchanger is clay (for example bentonite), silica gel or zeolite.Usually make water as working media for these absorbing materials, glassware for drinking water has the high condensation heat of 2000kj/kg and undoubtedly is hands-down working media therefore.
Strictly speaking, represent to bear the working media of phase transformation with two different technical terms.To be absorbed, also do not have absorbed working media to be expressed as absorbate, in contrast, be expressed as absorbent by (absorption) working media addition or storage.In order to reduce the quantity of different definition in this manual, though working media is expressed as absorbate in its phase state, it is also referred to as absorbent or sorbent absorbs in absorbing material in certain state.
It is potential hot memory and absorption heat pump that the typical case of adsorption heat exchanger uses.At first memory is used for heat energy, and secondly absorbing material is used in heat pump techniques.
For example carry heat energy to give adsorption heat exchanger from the outside by the percolation that utilizes thermal liquid, the heat that must flow into from the outside is transferred to absorbing material in efficient mode so, so that discharge the working media that is adsorbed that is arranged in absorbing material.For opposite situation, discharge (ausspeichern) heat energy, promptly the energy flow direction is outside from adsorption heat exchanger, the heat energy that discharges based on the condensation of the working media on the absorbing material is transported to the outside from adsorption heat exchanger once more.Because the known absorbing material has relatively poor thermal conductivity, to have higher thermal conductive and have the combination of the heat exchanger structure of absorbing material so adsorption heat exchanger manufactures usually, and this absorbing material is used for combination and discharges working media.Heat exchanger structure for example is made of copper, aluminium or stainless steel mostly by metal material, also can use to have conductive other material of higher thermal, for example pottery or specific plastics.
Heat exchanger has in the subregion at least and is used for the hollow body that heat-carrying agent flows, but this heat-carrying agent self usually with absorbing material directly contacting.Subsequently heat exchanger structure once more with the absorbing material thermo-contact.Incoherent pouring into will be taken place in the simplest situation, wherein this absorbing material be mostly Powdered or by with the mixed spherical shape that is of adhesive.But the structure of this simple realization has more shortcoming.Promptly there is the relatively poor heat transmission between absorbing material and the heat exchanger structure wall mostly.This is not in heat exchanger structure for those of absorbing material, and directly to be close to the zone that contacts (anlagekontakt) more unfavorable.
Another problem is that vaporish absorbate flows to absorbing material as well as possiblely.But prerequisite is, the microcosmic loose structure that promptly additionally is used for absorbing material has and is used for the continuous channel system of transit steam shape working media with thermal conductivity.When in the simplest situation, absorbing material being put into prefabricated heat exchanger structure as mentioned above, be noted that so to keep this channel system in absorbing material to be used for the vaporous absorbate by the method for pouring into.Prerequisite is, i.e. compressed absorbent material consumingly.In order to address this problem, put into granular absorbing material mostly or the spherical shape absorbing material replaces Powdered absorbing material at this.But this also has shortcoming, is that the structure contact of point-like also can make the heat conduction variation that derives heat exchanger structure and import heat exchanger structure by the major part between the single particle of absorbing material promptly.
Therefore, for the efficient adsorption heat exchanger of design, exist the goal conflict.On the one hand, thermo-contact as well as possible is important between absorbing material and heat exchanger structure.On the other hand, must keep the open porous structure of absorbing material and in absorbing material, additionally be configured for transmitting the macroscopic path system of gaseous state absorbate.In order to address this problem, the heat exchanger structure to small part in more known adsorption heat exchangers is made of the metal sheet or the sheet metal that have set in advance the absorbing material coating.Disclose the manufacture method of the sheet metal of coating by JP11300147A, in its surface absorbing particles has been embedded adhesive phase at least in part.Also cover this absorbing particles by the film that flatly applies.In order to constitute the shape that adsorption heat exchanger is folded into the sheet metal of coating like this honey comb structure.
By DE 4129700C2 a kind of method that is used to make the adsorption heat exchanger parts is disclosed in addition.Constitute the adsorption heat exchanger parts at this by a large amount of flat boards, wherein each plate has carried the coating that has adhesive phase and be arranged in the inorganic absorbing particles of adhesive phase.In order to finish this adsorption heat exchanger parts, make the part of this plate wrinkling and to utilize substep be that the order of a wrinkling plate and a flat plate constitutes pile system.Making dull and stereotyped starting point is the aluminum slice with 30 μ m material thicknesses, and the two sides all utilizes and rolls rod and coat the adhesive phase with 10 μ m-30 μ m thickness on this aluminum slice.Used the adhesive that is selected from the polyvinyl acetate group at this.At first partly dry this adhesive, thereby also still also not curing of toughness of adhesive phase.Then, the synthetic zeolite granular of diameter＜100 μ m is blown on the adhesive phase, wherein zeolite granular embeds adhesive phase substantially fully and forms 12g/m
2The loading of zeolite.Beginning is heated to 100 ℃-250 ℃ temperature in short time within about 10s in further method step.Discharge the gas in the hole that locks into zeolite granular by this Fast Heating process, be configured for the passage that more late gas between the surface of zeolite granular that embeds and coating exchanges thus.For the formation suggestion that improves passage is put into adhesive with extra swelling agent.In the dry heat device, solidify and the dry adhesive layer subsequently.
The adsorption heat exchanger that is made of the thin metal layer that utilizes the absorbing material coating has advantage, promptly can design modestly at the wall of heat exchanger structure and the contact area between the absorbing material.Can be provided for the suitable channel system of vaporous absorbate in addition by the corresponding 3D shape of thin metal layer structure.But the shortcoming of this set is, all is that cost is too high except the extra work step that is used for coating also has the continuation of the sheet metal after applying coating to handle.Must handle this sheet metal carefully based on coated absorbing material.In addition, most of thin sheet metal defines the stability of its static(al).In the formation of heat exchanger structure, two key elements make design as far as possible freely difficult more.To consider that in addition known sheet metal coating is restricted in the loading of its absorbing material.Higher loading density is a prerequisite with bigger absorbing particles, but utilizes known sheet metal coating process can only obtain bigger absorbing particles restrictedly.
Disclose a kind of manufacture method that is used for adsorption heat exchanger by JP 2000018767A in addition, wherein at first constituted heat exchanger structure, then filled this heat exchanger structure with absorbing material and adhesive.In order to walk around foregoing problems, will put into this heat exchanger structure by the thing that pours into that the plastic adhesive of absorbing material and heat back is formed.Not only absorbing material but also adhesive are granular shape, and wherein the particle size of the particle size of absorbing material and the sort of adhesive is coordinated mutually.In the heating steps of following, melt adhesive and each absorbing particles substep point-like is interconnected.When selecting the particle size of the plastic adhesive in heat back, also further be created in the space between the single absorbing particles when abundant so after the thawing step of adhesive, this space is used to transmit the gaseous state absorbate littlely.This program list reveals the improvement of pouring into incoherent, considers that not only heat conductivity between the absorbing particles is also based on the mechanical fixation of absorbing material.However in this system, also have problems, promptly do not have suitable channel system in order to abundant transmission gaseous state absorbate.Also be created in some zones in the absorbing material, at first, this zone is poured into thing and is had spacing certain and wall heat exchanger structure based on putting in fits and starts, and thus only significant adverse in the heat transmission of deriving and importing heat exchanger structure.
Summary of the invention
The objective of the invention is to, a kind of method that is used to make adsorption heat exchanger is provided, this method at first from freely design and and the heat exchanger structure of substep structure, this heat exchanger structure is connected with absorbing material subsequently.The coupling system that is made of heat exchanger structure and absorbing material can have high thermal conductivity between the wall of heat exchanger structure and absorbing material, the present invention has realized transmitting as far as possible efficiently the structure of gaseous state absorbate to the microcosmic porous of absorbing material in addition.In addition, this characteristics that are used to make the method for adsorption heat exchanger are, it can easier realization, and this method can produce the adsorption heat exchanger with the attached ability of high adsorption/desorption that is used for absorbate.
This purpose realizes by independent claims.Dependent claims has provided preferred embodiment.
In order to realize that this purpose inventor at first recognizes, must be with absorbing material with on the granular inner face that adheres to heat exchanger structure like this with abundant particle size, each granular solid matter that is absorbing material only partly embeds adhesive phase, the major part that is the granular solid matter surface can also interact with the gas phase of absorbate, and the wall of each this granular solid matter of while and heat exchanger structure is in thermo-contact fully.In a preferred embodiment, the granular solid matter of all absorbing materials all should have wall bonding of this and heat exchanger structure.Be created in the channel system of the macroscopical porous in the adsorption heat exchanger by this way, this passage can be used for transporting efficiently the gaseous state absorbate.
Manufacturing at first is the heat exchanger structure that substep is made according to the starting point of adsorption heat exchanger of the present invention.Make this heat exchanger structure according to known method by the material of high-termal conductivity.Suitable to this is metal system, for example copper, aluminium or stainless steel.Also can use ceramic material or synthetic material system to this.Suitable heat exchanger structure can be used for the circulatory system of heat-carrying agent, and this heat-carrying agent is connected with the perimeter of adsorption heat exchanger.In addition, in order to be embedded in heated wire or other thermal source to the heat exchanger structure heating.In order to produce the preferred stratiform in big as far as possible surface or the honey comb structure of absorbing material system.This structure also can be spongy or foam-like.From this heat exchanger structure of making at first step by step, present following undercoating with absorbing material:
In first method step, with adhesive phase be coated to heat exchanger on the wall of absorbing material, this wall is called as inwall below.This has been used adhesive, it at first constitutes the layer of solid.In order to realize that this adhesive phase can use diverse ways, for example floods, casts or spray.The method step of adhesive coating can further repeat so that the layer thickness of optimization to be set.This this is particularly advantageous, promptly for example adjusts the viscosity of coated adhesive by heating or by increasing solvent or evaporating solvent.Possibility also can be will be in adhesive solid, pulverulence and be arranged on the wall of heat exchanger.This powder coating is used in particular on the smooth heat exchanger structure.This external heat exchanger can at first be filled with powdery adhesive, subsequently this adhesive again near the zone the wall of heat exchanger by heating is activated to heat exchanger structure, thereby can appear near the wall the zone adhesion and then from away from the zone of wall for example by shaking, blow or clean jointing material that removal does not adhere to, pulverous.Irrelevant with the selection or the selected painting method of adhesive, adhesive phase adheres in must near the zone wall at least so securely, and the mixing of infringement function of adhesive and absorbing material promptly do not take place at subsequently the method step of wherein absorbing material being put into heat exchanger.
Suitable bonding has following characteristics, and promptly it melts when being higher than first temperature and hardens when being higher than second temperature, and second temperature is higher than first temperature.Particularly epoxy resin proves a kind of suitable bonding.Adhesive based on epoxy resin melts when being higher than first temperature, and this first temperature is typically 50 ℃-70 ℃.Harden when being higher than second temperature, this second temperature is in 100 ℃-200 ℃ the scope, wherein takes place crosslinked in epoxide-resin glue and epoxide-resin glue so is hardened to and has higher temperature stability and thermosetting plastic corresponding high glass-transition temperature.
In first method step in order based on the situation of the adhesive of epoxy resin the time, preferably to use solvent such as acetone, MEK or carrene constituting solid-state adhesive phase on the inwall, so that adhesive is at first liquefied.In order to apply this fluid binder, heat exchanger structure is immersed epoxy resin solution.Unnecessary adhesive also is removed and adhesive phase at first is dried to solid-state subsequently from heat exchanger structure with liquid state, promptly substantially no longer sticking adhesive phase.For the layer thickness of adjusting adhesive layer can be for example by adjusting solvent or temperature to regulate the viscosity of adhesive.Also can expect in addition, apply more multi-layered adhesive phase by repeating aforementioned job step.Can be with adhesive spray as other application of adhesive layer method in addition or smear heat exchanger structure.In addition, replace utilizing solvent to liquefy, can reach and reduce viscosity until liquid state by the temperature of regulating adhesive and/or heat exchanger structure.Curing adhesive layer after application of adhesive.This again can by reduce temperature or by sufficient time of repose until solvent evaporates.
When utilizing granular absorbing material to fill the heat exchanger structure of preparing so subsequently, the absorbing particles of putting into substantially when not having extra heat treatment and covering does not produce bonding between the adhesive phase of heat exchanger structure inwall so.This has advantage, promptly controllably makes bonding by this way and only realizes bondingly for those absorbing particles, and this absorbing particles is in directly to be close to the inwall of heat exchanger structure and contacts.Give the adhesive phase transfer heat at this.This can be at first by putting into heat exchanger structure heating cabinet and/or baking box or coming transfer heat with ultrared radiation.This heat input or energy input also can be called the energy input from the outside.For example also can consider inductively heating heat exchanger structure.Also can be the heat exchanger structure heating internally by the heat-carrying agent of input relevant temperature.In another design, can import the absorbing material that has heated.
At this based on the control heating like this of perdurabgility and selected temperature trend, promptly from the particle size of average adhesive thickness and selected granular absorbing material, be close in the zone (anlagebereich) with the adhesive that melts at it adjacent to the absorbing particles on the heat exchanger structure wall wetting, but the major part on absorbing particles surface is also protruded from adhesive phase simultaneously.Therefore particle invades in the adhesive phase, but is not surrounded fully by the adhesive layer, thereby particle can exchange with absorbate, and promptly particle is available in the absorption and the desorption and therefore available in the potential heat of conversion of absorbate.
Then the temperature in the heat exchanger structure is brought up to and surpassed second temperature, the sclerosis of generation adhesive phase when second temperature.Under the situation of epoxide-resin glue, take place final crosslinked and change thermosetting plastic into subsequently.After this cross-linking process that is higher than second temperature or hardening process end, for be directly adjacent to granular absorbing particles on the heat exchanger structure wall produce firm, particularly temperature stabilization is bonding, and do not damage absorbing particles with adsorption heat exchanger inside in the interaction ability efficient exchange of absorbate (promptly with) of environment.
In another advantageous method step, will not remove from heat exchanger structure with the regional bonding absorbing particles of wall.This is for example by mechanical means (as shaking) or by providing negative pressure to take place.Produce macroscopical cavity and passage by these methods, the gaseous state absorbate can flow through these cavitys and passage.Take place thus the absorbate of gaseous state is transported to absorbing particles bonding on the heat exchanger structure wall fully.These absorbing particles are in enough good thermo-contact with heat exchanger structure again, thereby discharge or the potential heat of combination also flows into by heat exchanger structure effectively and flows away by exchanging mutually of absorbate.
In the optional design of the method according to this invention, be used for making connect absorbing particles, do not activate at the adhesive phase of wall near zone.As an alternative, be coated to the local distribution that method step on the heat exchanger has guaranteed the desirable adhesive in the wall near zone by adhesive.This can for example take place by utilizing powdery adhesive to fill heat exchanger structure, this powdery adhesive obtains its bonding force by the heating heat exchanger structure subsequently in the wall near zone, wherein adhesive keeps inviscid and Powdered substantially in away from the wall zone.Subsequently inviscid part is taken out from heat exchanger.This preferably the mechanical means by help property as shaking, blow or cleaning and realize.Smooth adhesive phase keeps its adhesion properties in the wall near zone, promptly after putting into absorbing material, activates dispensable for present embodiment.

The specific embodiment
Show to simplified schematic the heat exchanger structure with thin layer 2.1,2.2 in Fig. 2, this thin layer is made of the conductive material of higher thermal.Usually use metal, for example copper, aluminium or stainless steel at this.In addition, heat exchanger structure preferably has the cavity 3.1,3.2 that is used for heat-carrying agent (WTM) circulation.Heat-carrying agent (WTM) by circulation in this cavity 3.1,3.2 is given later adsorption heat exchanger with heat delivery, and from its release.Typically, such heat exchanger structure is to match with container, the gas phase of this seal of vessel absorbate and thereby surround the operating room, the operating room is illustrated as interior zone 4 in this application and is used to hold absorbing material and absorbate S.This interior zone is relevant with the use of adsorption heat exchanger again with respect to the sealing mode of perimeter.Can consider that so also adsorption heat exchanger is presented to and makes absorbate enter the system of second area from the first area, adsorption heat exchanger is arranged in this first area.
In an embodiment, the heat exchanger structure in interior zone 4 comprises the stratiform fin, and this fin has the thin layer spacing of 4mm.This heat exchanger structure and other heat exchanger structure are filled with the absorbing material of varying particle size.In other test, use the heat exchanger structure of thin layer spacing with 1.6mm, 2.3mm, 4mm and 6mm, wherein the particle size of granular absorbing material be change and be adapted to each thin layer spacing.The thin layer spacing of heat exchanger structure begins to be adjusted to each particle size from the minimum spacing of 4mm.Copper that uses as material and aluminium are as thin layer.In this decision design the thin layer of structure is arranged, in other words, thin layer is made into the Zhe shape or jagged, so that high area-volume ratio is provided as much as possible.
With reference to Fig. 2, the heat exchanger structure of being made by substep sets out, and according to first method step that is used for interior laminate layer, covers with the adhesive phase of the wetting inwall inner surface with heat exchanger structure, and this adhesive phase constitutes solid-state layer before filling with absorbing material.In this application, this solid-state adhesive phase is interpreted as and farthest loses bonding force, and this is by dry or the suitable adjustment of adhesive phase reached fully for a long time usually.According to first embodiment, use epoxide-resin glue as adhesive, on the inwall that adhesive phase is coated in heat exchanger structure and this epoxide-resin glue and solvent (for example acetone) are mixed.This epoxy resin solvent mixture is applied in the interior zone 4 of heat exchanger structure, remove unnecessary adhesive by zone drippage internally then, thereby continuous substantially adhesive phase is preferably placed on the inwall of heat exchanger structure, and can not stop up (verstopfung) layer structure.In other words, adhesive phase is preferably along the profile of inwall and do not reduce the area of heat exchanger structure inwall substantially.For epoxide-resin glue, solvent evaporates and adhesive phase curing thus after the time of repose of abundance, occur, thereby solid-state adhesive phase 5 covers inwalls when this method step finishes with solvent part.In this embodiment, quicken this curing schedule or drying steps by 50 ℃ Temperature Treatment, to carry out this dry approximately through time of 3 hours in later stage.
Arrange the layer thickness of adhesive phase according to the size distribution of absorbing particles.For example, when using magnitude range to be the absorbing particles of 10 μ m-1000 μ m (preferred 20 μ m-50 μ m), regulate the thickness of adhesive phase so like this, promptly when preparation was used for absorbing particles bonding, this adhesive phase is partly wetting this absorbing particles only.To this in a preferred embodiment, layer thickness is arranged in 1/3rd to 2/3rds the scope of particle diameter, and particularly in 1/3rd to 2/3rds scope of average particulate diameter.In particularly preferred embodiment, the coating layer thickness of adhesive phase is the mean value of half granular size of absorbing particles, promptly adopts the layer thickness of its radius as adhesive when being the absorbing particles of circle substantially substantially.When the spherical absorption particle is the size distribution of 100 μ m-200 μ m, preferably coat the adhesive phase of 50 μ m average layer thickness thus.
Be further method step in Fig. 4, promptly show the filling of granular absorbing material.For example can use synthetic zeolite for preparing or silica gel as absorbing material.Active carbon also is suggested as absorbing material.According to first embodiment, use the absorbing material granularity of 0.8mm-1.0mm.In other embodiments, use the absorbing particles of Size Distribution to be used for according to adsorption heat exchanger of the present invention with 100 μ m-200 μ m and 1mm-2mm.Can guarantee that advantageously this absorbing particles is filled in the areola in the heat exchanger structure fully by mechanical means (for example by shaking or pushing to a certain degree).For this situation, promptly constitute heat exchanger structure like this, promptly interior zone 4 does not have to be surrounded by the structure of Container Type fully before putting into absorbing material, can wrap up this heat exchanger structure by accurate framework suitable, that cover with the paper of silication (silikoniert) so.Such heat exchanger structure of opening to small part in coating area can be placed in the suitable containers in method step subsequently, and this container is used to seal the working region that comprises absorbing material and absorbate.
Directly after putting into absorbing material, between solid-state adhesive phase 5 and absorbing material 6, there is not bonding contact (klebekontakt) substantially in discontinuous mode of pouring into.This at first obtains by further heat treatment step, wherein by bonding formation between the absorbing particles 6.1 of selecting temperature curve to realize to be controlled at exactly initial hard adhesive phase and direct neighbor.In order to implement this method step, the adhesive 5 that applies with the form of solid layer also must have this specific character, this adhesive volatilization and sclerosis (second temperature is than first temperature T, 1 height) when being higher than second temperature T 2 when promptly being higher than first temperature T 1.Realize the characteristic of this requirement by epoxide-resin glue.Usually for epoxy resin, first temperature T 1 in this embodiment (adhesive melts when this temperature) is positioned at 60 ℃-66 ℃ scope.For epoxy resin is 120 ℃ to 140 ℃ temperature, particularly 120 ℃ can be with as second critical-temperature, this critical-temperature realizes the final sclerosis (solidifying in other words) of adhesive phase.By proceed to the temperature gradient of the temperature that is higher than second temperature from the temperature that is lower than first temperature, at first begin to melt initial solid-state adhesive phase 5.The absorbing particles 6.1 of the wetting direct neighbor of adhesive thus, or rather preferably like this, promptly this absorbing particles also protrudes from adhesive phase with its dominant surface portion.In further temperature elevation process, surpass second temperature subsequently.Thermosetting plastic crosslinked and its formation temperature stabilization appears when epoxide-resin glue.According at the embodiment shown in this, the time heating heat exchanger structure that continues 30 minutes by the thermal liquid that has 180 ℃ with importing reaches heating to melt adhesive phase, bonding with absorbing particles that wall is adjacent and finally harden.
In further method step, will promptly remove in zone 4 internally less than what adhere to subsequently away from the absorbing particles of wall.This realizes by suitable mechanical means (for example by shaking) once more.Generation as a result of has the internally coated heat exchanger structure that is made of absorbing material, is schematically shown in Fig. 5 as it.Absorbing particles only covers inwall and substep sticks on this inwall, wherein only formed to point-like bondingly, promptly absorbing particles protrudes and exchanges with the absorbate that is transfused to its at utmost intact untreated surface beginning from adhesive phase with major part.Except the near wall region territory,, in interior zone 4, there is not the absorbing particles that does not have adhesion according to preferred embodiment.Therefore can realize that absorbate unhinderedly flows to absorbing particles, promptly remaining with fully in interior zone 4, big zone is used for the absorbate that heat is conducted ground delivering vapor shape.Schematically showing the expedite of the absorbing particles 6.1 of this absorbate S on inwall (having good thermo-contact based on bonding this inwall) in Fig. 1 once more flows.Reference identification among other reference identification and Fig. 2 to Fig. 5 is corresponding.
Other advantage that at first forms hard adhesive phase on the inwall of heat exchanger structure is, the layer by forming sealing is simultaneously also to realizing the metal part anti-corrosion protection of heat exchanger structure.According to prior art pour in fits and starts absorbing material or only the absorbing particles that is bonded to each other of point-like can not obtain the protection of this heat exchanging modulator material.Except covering the heat exchanger structure inwall substantially fully, this is more important for anticorrosion fully, and promptly adhesive phase is closed substantially, and adhesive phase is not a porous in other words.This obtains by forming the adhesive phase with sclerosis at first solid-state and that melt by heat treatment subsequently.
Can expect other embodiments of the invention.So, for example can change the type of absorbing material.Can use zeolite corresponding to advantageous embodiments of the present invention, its granularity with 0.2mm-0.3mm is used for interlamellar spacing with 2mm with potential heat exchanger (latentwaemetauscher) coating.The preferred particle size that makes absorbing material thus is adapted to the geometry of heat exchanger structure.Therefore the absorbing material of low particle size (for example 100 μ m-200 μ m) and those absorbing materials with bulky grain size (for example 1mm-2mm) are advantageous for corresponding suitable heat exchanger structure.Preferred especially homogeneous granules Size Distribution, reason are, obtain adhering to equably the layer that sticks together by absorbing material homogeneous granules Size Distribution on the heat exchanger structure inwall.Can also mix different particle sizes according to other structure and be used for absorbing material.For example, can use bimodal particle size distribution, this is favourable when using coarsegrain especially.Utilize the method according to this invention also big absorbing particles and the bigger absorbing particles with 1mm-2mm diameter can be adhered on the inwall of heat exchanger structure, can realize every square metre of coating thus with 60g-500g absorbing material.So big absorbing particles protrudes from adhesive phase fully far, offers absorbate surface big, that can be capped diffusely thus.By using extra little absorbing particles can cover the gap that produces between this big absorbing particles on the heat exchanger structure inwall, improved the loading density of absorbing material thus once more.
Utilize the method according to this invention also can use absorbing particles in irregular shape, be used to the heat exchanger structure coating.What so also can expect is to use particle size at random and absorbing material that have the chip shape of wide scattered particle size distribution.This also comprises part and bigger fragment and the corresponding mixture that the two forms by it of using dust-like.Can consider that so also smaller particles is also just partly wetting by the adhesive layer respectively as bigger particle, especially by only being the thawing on nearly surface or by realizing until the zone of adhesive sclerosis via melting the zone fast.In addition, also the wetting characteristics of adhesive can be adapted to selected absorbing material, thereby though realize that absorbing particles sticks on the wall of heat exchanger structure, the other parts on absorbing particles surface can be carried out and exchange absorbate expedite.
