Description

Hot wall type heat exchanger

Technical field

The present invention relates to field of heat exchange, more particularly to a kind of hot wall type heat exchanger.

Background technology

Human civilization progress increasingly be unable to do without the energy, and the exploitation of the energy and occupation mode also need further improvement badly, Human development is produced and the use of 80% can be almost had more than in energy processes is to need heat energy to change, and heat energy is changed from not All kinds of heat exchangers are driven, therefore, heat exchanger ought to turn into the equipment of energy-saving and emission-reduction most critical.Especially today's society Facing Natural Environment Greenhouse gas emission and bring lot of challenges and the worry of mankind's survival to the mankind, earth glacier is in ablation state, pole Ground ice cap little by little diminishes, and extreme weather occurs every now and then, and this is constantly raised in sea level all turns into undisputable fact.Section Energy emission reduction, elimination haze are also shouldered heavy responsibilities, and this is as one of top priority of our Party and government.

The current all kinds of heat exchangers generally used cause them using due to respective characteristic and their own limitation On can only all service some field rather than whole, such as, be able to can not be used in the equipment of air heat-exchange two liquid it Between heat exchange, and the equipment that can be exchanged heat between two liquid can not allow this equipment to be used for air heat-exchange, and low available for low pressure The equipment of warm environment heat exchange can not but allow it to be used for high temperature and high pressure environment heat exchange.And also show：Efficient person is not pressure-resistant, and resistance to The not efficient awkward situation of pressure person；Or the heat exchanger of cleaning easy to disassemble but not enough seal it is pressure-resistant；Volume is heavy, otherwise cost Cross high shortcomings.Above present situation just causes current all kinds of heat exchangers respectively to account for one seat by intrinsic advantage, although some Certain common factor can be formed in application, but plate type heat exchanger definitely may not be usable for air heat-exchange, also never can be Used in high-pressure high-temperature environment, especially regrettably central air-conditioning so far all can not use plate type heat exchanger be used as evaporator with it is cold Condenser, although and shell-and-tube heat exchanger high temperature high voltage resistant, efficiency is low, heavy occupation of land side, cost are high；And between plate type heat exchanger Although lamella heat exchanger efficiency between shell-and-tube heat exchanger is than high twice or so of shell-and-tube heat exchanger, pressure high-temp resistant degree Twice is higher by than plate type heat exchanger to have a surplus, but manufacture craft requires high, and welding portion is more, and the tube sheet machining ratio of fixed plate pipe The tube sheet of shell-and-tube heat exchanger is much more difficult, and general user is difficult to receive its purchasing price, and is difficult to minimize；And tubular type wing Piece heat exchanger, plate-fin heat exchanger and micro-channel heat exchanger are only suitable for the cooling of water, oil, vapour, and respectively have application, plate-fin The heat exchange of the suitable gaseous fluid of heat exchanger and air, but corrosion-resistant, the small-scale air heat-exchange efficiency of micro-channel heat exchanger are non- Chang Gao, and the embarrassed important task that exchanges heat on a large scale, tubular type finned heat exchanger belong to the more common aerial cooler of Low investment cost, but Efficiency is bad；The energy-efficient heat pipe equipment that especially professional speaks approvingly of for it, although its application is in recent years Expand, but because its fitting structure form can not also use in larger scope, easy dust stratification blocks up air channel, also space-consuming, because All there is defect in structure in existing heat pipe either radial heat pipe or axial heat pipe, they are all cylindrical first, circle Cylindricality is in addition to pressure-resistant advantage, and its heat exchange surface area is more much smaller than board-like in the case of equal volume, and inner side Fluid boundary layer is easily formed, outside is big to duct resistance.At present industrially using it is more be axial heat pipe, but with production The continuous improvement of upper heat exchanging equipment requirement, the limitation of axial heat pipe in use is more and more prominent, is mainly manifested in Following several respects：Heat pipe used in existing liquid phase heat exchange of heat pipe (hot fluid is process gas, and cold fluid is water) is axially Heat pipe (being mostly gravity assisted heat pipe), mainly there is two kinds of box-type and separation sleeve pipe formula.This kind of heat pipe is axial along pipe by gravity Working media evaporative condenser is realized, re-evaporation condenses the circulating heat transfer course of work gone round and begun again again, therefore is heated at work Duan Bixu is in the bottom of pipe, and heat release section then must just be difficult to the transmission of heat on the top of pipe, when horizontal, by axial direction The heat exchange of heat pipe of heat pipe composition is used for the heat exchange of horizontal direction streaming flow, and being difficult in the fluid of perpendicular flow should With.Axial heat pipe heat conduction vertically, incoagulable gas are readily collected in the end of heat release section, and isothermal performance is affected, and reduce The heat transfer property of heat pipe.To be analyzed from manufacturing process, axial heat pipe pad is more, and sealing is also highly difficult, once let out It is hardly imaginable to leak consequence.Box-type heat pipe can not bear water lateral pressure, and separation sleeve pipe formula can bear water lateral pressure, its water-flow chart It is more complicated, cause water collateral resistance to increase.The continuous expansion that radial heat pipe is applied in the industrial production with axial heat pipe, it is above-mentioned Shortcoming has hindered its development in each field.Such as in sulfuric acid industry, due to the reasons such as the limitation in place, technological requirement heat Pipe must be arranged vertically, and can not have leakage, and the heat pipe of above two structure is difficult to accomplish.Exchanged heat for this new heat pipe Device-- radial heat exchanger arises at the historic moment.Radial heat pipe has just occurred early in last century 60, the seventies, but former radial direction The main function of heat pipe is to provide a constant temperature field, such as epitaxial furnace isothermal heat pipe, quartz crystal tester isothermal heat pipe, temperature system Number testboard isothermal heat pipe, French Sodern heat-pipe constant-temperature stove etc. are all to belong to this category.Nanjing University of Technology's heat pipe is ground Study carefully expert breach limitation of the radial heat pipe only as constant temperature field, using radial heat pipe as transmit heat heat transfer element enter Row is developed, and is manufactured by Kesheng High-temp Heat Pipe Equipment Manufacture Co., Jiangsu and is come into operation.Because its function becomes, within institute Portion's structure also accordingly changes, and this is mainly reflected on liquid sucting core structure.As the heat pipe of isothermal body, its liquid-sucking core is typically arranged, is removed It is furnished with tube cavity wall outside liquid-sucking core, is also separately covered with spoke liquid-sucking core.Vapour, the flow velocity of liquid two-phase are very low in such heating pipe, It is critical that vapour, gas-liquid two-phase liquid will be full of whole cavity, is allowed to be in an abundant and complete saturation state, so as to shape Into an isothermal body, so liquid-sucking core will be covered with whole inner chamber.And as the radial heat pipe of heat transmission, vapour, the stream of liquid two-phase Speed is relatively higher, and its key is the liquid that heat-absorbent surface must assure that abundance, in order to avoid dry up, therefore general is absorbing heat Applied at face and put liquid-sucking core, and the unobstructed flowing of steam can be hindered and add heat transfer resistance on the contrary by excessively arranging liquid-sucking core.

Now enumerate good and bad situation possessed by radial heat pipe：(1) heat pipe used in radial heat exchanger is footpath Liquid-sucking core is furnished with into heat pipe, fluid reflux is realized under capillary force action, therefore the operating position of heat pipe and fluid Flowing it is unrestricted, can with comprehensive work, be particularly suitable for use in hot fluid must vertical direction flowing occasion, it is another There is capillary tension in aspect capillary, this tension force can show the resistance of fluid, influence whether phase change fluid heat transfer rate. (2) radial heat exchanger is compared with axial heat pipe heat exchanger, and in the case for the treatment of capacity identical, equipment is compacter, typically Volume can reduce 30~40%, and weight can mitigate 15~20%.(3) radial heat pipe can more effectively control wall surface temperature, due to The area of its hot side is far longer than the area of cold side, so wall surface temperature can be improved preferably, but can cause both sides heat-energy transducer Power, which does not match that, can waste metal material.(4) radial heat pipe has very high isothermal performance, and incoagulable gas influences relatively on it Axial heat pipe is small, and heat transfer property is relatively preferable, but extracts incoagulable gas and have certain difficulty.(5) radial heat pipe exchanges heat The flow resistance of the side liquid of device two is smaller, and the operating cost of equipment is low.But radial heat pipe incrustation scale can not get effective washing, Admixture is at the liquid phase in its phase change fluid as axial heat pipe and gas phase, hinders gas-liquid two-phase to a certain extent Shunting.

Excellent isothermal：The steam of heat pipe inner chamber is to be in saturation state, and the pressure of saturated vapor is decided by saturation temperature Degree, saturated vapor flows to pressure drop very little caused by condensation segment from evaporator section, and it can be seen from the equation in thermodynamics, temperature drop is also Very little, thus heat pipe has excellent isothermal.

Heat flow density changeability：Heat pipe can independently change the heating surface (area) (HS of evaporator section or cooling section, i.e., added with less Hot area inputs heat, and heat can be inputted with larger heat transfer area with larger film-cooled heat quantity of heat given up, or heat pipe, And with less film-cooled heat quantity of heat given up, it can so change heat flow density, it is insoluble to solve some other methods Heat transfer problem.Heat pipe also has reversible heat transfer characteristic and thermal switch effect, can also be used to thermostatic effect etc..

The advantage and disadvantage and the state of the art of major heat exchanger species are set forth above, we can collect all kinds of heat exchanger advantages Great achievement, and the more extensive heat transfer technology of application fieldBoth can be efficient as plate type heat exchanger, again can be with image tube shell Formula heat exchanger high temperature high pressure resistant like that, and being exchanged heat at a distance as heat pipe again, using it is upper also easily, especially in maintenance side Face is more convenient than existing heat pipe, and we are by the exploration and research repeatedly made great efforts herein, and we have studied " multilayer coaxial circles in advance Cylinder finned heat exchanger ", and corresponding patent of invention and utility model patent have been invented, because we have found in implementation process There is the defects of many in multilayer coaxial cylinders finned heat exchanger, and carry out many place innovations, because previous multilayer coaxial circles Cylinder finned heat exchanger profile is cylindrical, and drum use range is narrow, such as rectangular when with air heat-exchange and circle The circular demand for being more suitable for application scenarios of the ratio of angular moment shape, if in the case of height-limited system, its heat exchange area is difficult to expand, The demand of its heat exchange amount certainly will be influenceed, and round rectangle heat exchanger more saves space；The multilayer coaxial cylinders of prior inventions Finned heat exchanger patent of invention and utility model patent can not realize that remote phase transformation mode exchanges heat as heat pipe, therefore it It is the heat exchange for being not used as new blower fan, multilayer coaxial cylinders finned heat exchanger is used as being only suitable for horizontal heat exchange when non-air exchanges heat.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only the part of the embodiment of the present invention, rather than whole embodiments.Base Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its His embodiment, belongs to the scope of protection of the invention.

It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only used in the embodiment of the present invention In explaining the relative position relation under a certain particular pose (as shown in drawings) between each part, motion conditions etc., if should When particular pose changes, then directionality instruction also correspondingly changes therewith.

In addition, in the present invention such as relating to the description of " first ", " second " etc. be only used for describe purpose, and it is not intended that Indicate or imply its relative importance or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", At least one this feature can be expressed or be implicitly included to the feature of " second ".In the description of the invention, " multiple " contain Justice is at least two, such as two, three etc., unless otherwise specifically defined.

In the present invention, unless otherwise clearly defined and limited, term " connection ", " fixation " etc. should be interpreted broadly, For example, " fixation " can be fixedly connected or be detachably connected, or integrally；Can be mechanically connect or Electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, can be the connection or two of two element internals The interaction relationship of individual element, limited unless otherwise clear and definite.For the ordinary skill in the art, can basis Concrete condition understands the concrete meaning of above-mentioned term in the present invention.

In addition, the technical scheme between each embodiment of the present invention can be combined with each other, but must be general with this area Logical technical staff can be implemented as basis, will be understood that when the combination appearance of technical scheme is conflicting or can not realize this The combination of technical scheme is not present, also not within the protection domain of application claims.

It is understood that heat exchanger energy-saving significance is great, most people thinks that coefficient of heat transfer height will save, in fact heat exchange system The high simply explanation heat transfer rate of number is fast, can save heat exchanger metal material, reduce cost of investment, heat transfer rate is soon certain The meaning for having energy-conservation can also be illustrated in degree, but it is also exactly so, and maximum energy-conservation is meant that and is that the end of heat-exchange temperature is poor： That is heat exchanging fluid inlet temperature and the difference by the outlet temperature of heat exchanging fluid, the smaller explanation of this difference more saves, Gone that is being transferred to greatest extent in heat exchanging fluid by the heat of heat exchanging fluid, the end difference of current plate type heat exchanger can be with 1 DEG C is realized, and the temperature end of at most namely 8 DEG C of shell-and-tube heat exchanger is poor (also having certainly can realize that 5 DEG C are held difference), because This plate type heat exchanger will save than shell-and-tube heat exchanger, but the application of plate type heat exchanger is also limited to, because it is resistance to It is not very high to press heatproof degree, although being increased according to the plate type heat exchanger pressure high-temp resistant degree of soldering, it does not have Method clean, using liquid medicine cleaning heat exchanger its service life can be made to be affected, and some dirt liquid medicine can not clean it is dry It is net, it is especially completely plugged in the case of liquid medicine also have no idea to reach the position of cleaning.Plate type heat exchanger is although energy-efficient, But it is not used as the plate type heat exchanger for still using sealing strip of the evaporator and condenser of central air-conditioning, either soldering They can not all be used, and be because the plate type heat exchanger of soldering can not clean, when system is cleaned using the plate type heat exchanger of sealing strip The fatal pain of injury for the reason for cryogen can be revealed, and the scope applied here it is plate type heat exchanger is extremely restricted, and the present invention is specially For profit just without the influence in terms of this, it can be efficient as plate type heat exchanger, can also image tube shell heat exchanger it is resistance to like that Press and be easy to clean, and can realize and be exchanged heat at a distance as heat pipe, absorb radial heat pipe and axial heat pipe advantage it Long, it is understood that heat pipe is using phase transformation mode remotely transferring, and heat transfer rate is fast, and heat flow density is big, and it, which exchanges heat, imitates Rate height is that other heat exchangers are all incomparable, and because phase transformation is exchanged heat in a manner of latent heat, this is passed compared with a manner of sensible heat Very it is not the heat transfer rate in an order of magnitude for heat, and the advantage that heat pipe also has a highly significant just can be achieved on Isothermal exchanges heat and 0.1 DEG C of temperature difference responds, and other heat exchangers can not all obtain.And the flow regime of existing pipe heat exchanger Determine that end Temperature Difference Ratio is higher (i.e. the difference of cooling water inlet temperature and cooled water outlet temperature) with two media flow direction, typically For 8 DEG C or so, if the end temperature difference of shell-and-tube heat exchanger the length of so this shell-and-tube heat exchanger must must be reached if 1 DEG C Grown to 80m, this is inconceivable in electric power factory equipment installation.

Flow regime and the two media flow direction of plate type heat exchanger determine end temperature difference very little, can economically accomplish 1 DEG C The temperature end of left and right is poor.This is in summer operating mode, the temperature of cooling water is higher, typically reaches 35 DEG C~38 DEG C.According to Plate type heat exchanger, then it is easy to make cooled coolant-temperature gage drop to 33 DEG C~37 DEG C, this guarantees Turbo-generator Set and subsidiary engine Nominal output and normal work (because generator cooling-water Wen Ruo be more than 37 DEG C then contribute will be impacted).And shell-and-tube heat exchanger The end temperature difference determine that under summer condition Turbo-generator Set and subsidiary engine can not ensure nominal output and normal work.

We can be found that when studying the existing all kinds of heat exchanger advantage chiefs：Optimization heat exchanger structure can not only make heat exchange Efficiency improves, and saves the energy, and convenient use, and heat exchanger structure most influences its heat transfer effect, and its meaning is far longer than The use of heat exchange new material, it is understood that copper material is more than ten times of stainless steel thermal conductivity factor, but using the plate-type heat-exchange of stainless steel The device coefficient of heat transfer be using three to five times of shell-and-tube heat exchanger of copper pipe, trace it to its cause do not lie in heat exchange material have how well Heat conductivility, also reside in heat exchanger structure and heat exchange mode, pure countercurrent flow is dominant on heat exchange mode, it is understood that board-like change Hot device is pure adverse current, and turbulent flow is eager to excel than vortex exchange capability of heat also in the heat exchanging fluid type of flow, because vortex is fluid court One direction rotational flow, the influence very little in this type of flow convection body boundary layer, causes thermal resistance to increase, the stronger explanation of turbulent flow Reynolds number is with regard to big, and turbulent flow can destroy the formation of fluid boundary layer, can reduce thermal resistance, this is also demonstrated in real product Point, than high twice or so of shell-and-tube heat exchanger if the heat exchange efficiency of lamella heat exchanger, both heat exchangers heat exchange process, In the case of flow, heat exchange partition thickness are much the same, their exchange capability of heat differences are that the heat exchanger channels of lamella heat exchanger are Non-cylindrical, but rectangular shaped post, this heat exchanger channels fluid can not form vortex, and shell-and-tube heat exchanger changes The passage of heat is cylindrical, and cylindrical channel is readily formed the vortex of fluid, so vortex convection body boundary layer destructive power is very Small, fluid boundary layer is thicker, and its thermal resistance is bigger, so as to reduce exchange capability of heat.Also although lamella heat exchanger changes than board-like The hot pressure-resistant degree of device is higher by twice and had a surplus, but high without plate type heat exchanger heat exchange efficiency, and what reason this is againBecause The heat exchange area of plate type heat exchanger is formed with parallel way, and the heat exchange area of lamella heat exchanger is most of such as Equally formed in a series arrangement with shell-and-tube heat exchanger, it is understood that heat exchange element connects in a series arrangement can increase its heat Resistance, and parallel heat exchanging element can reduce its thermal resistance, reason of searching to the bottom be due to its bigger heat transfer rate of the temperature difference it is faster (because The temperature difference is heat exchange sole power), heat exchange area series connection much, in heat transfer process more arrives the temperature difference below and decays more, because This heat exchange area forms the thermal resistance that can greatly reduce heat transfer process using parallel way, and this is heat exchanger innovative design maximum Application advantage, if shell-and-tube heat exchanger is designed using heat exchange area parallel connection advantage, the cost of heat exchanger can be significantly greatly increased, and And the too big existing machining apparatus of tube sheet diameter is all that the thing being difficult to (can realize the pipe of maximum gauge in the world at present The tube sheet of shell heat exchanger is 7.5 meters or so).And plate type heat exchanger have in heat exchange area parallel connection than shell-and-tube heat exchanger it is excellent Gesture.

Parallel Design is maximized according to heat exchange area to improve heat exchange efficiency；Can be greatly according to non-cylindrical heat exchanger channels Reduce the thermal resistance of fluid boundary layer；It is that heat exchange sole power is maximized heat exchange area parallel connection according to the temperature difference；According between heat exchange Wall thickness is thin to influence heat transfer rate, although and tubular type can be with thin, the thin necessary caliber of tube wall is small just can be with pressure-resistant, the small processing of caliber Tube sheet difficulty is bigger).Here it is three heat transfer theory bases of institute's foundation of the present invention；Technique realizes that the facility of condition is exactly this It is in parallel that the distinctive structure of patent of invention can cause heat exchange area to maximize, and is non-cylindrical heat exchanger channels bar, pressure-resistant Our uses of aspect expand folding and are easy to internal pressure to be delivered to outermost heavy wall ring, it is possible to achieve as plate type heat exchanger Heat exchange partition is thinned to improve its heat exchange efficiency.Contrast also according to existing product in optimization ease of use is more with me Year field of heat exchangers research and accumulation experience, accomplished compact-sized, easy to maintenance, blowdown is convenient, and cleaning is convenient, operates It is easy；Maintenance, blowdown, cleaning do not influence surrounding environment and equipment normal operation.An also unprecedented both sides cleaning is not With falling apart, without valve is closed, can be achieved to clean in operation, and existing plate type heat exchanger must fall apart cleaning (one One plate removes cleaning), and shell-and-tube heat exchanger can only clean side, and they can not all exchange heat at a distance, also can not be with Air heat-exchange.

The present invention proposes a kind of hot wall type heat exchanger.

Fig. 1 to Fig. 7 is refer to, in the present embodiment, the hot wall type heat exchanger includes hot wall 1, and hot wall 1 fills including inner support The heat exchange partition 5 of 2 and parcel inner supporting device 2 is put, is evacuated inside hot wall 1 and injects phase change fluid, inner supporting device 2 wraps The upper and lower side 4 for including the interlude 3 for being available for phase change fluid to circulate up and down and being available for phase change fluid or so to circulate；Hot wall 1 is rectangle, Several 1 clusters arranged side by side of hot wall of the same size, or, hot wall 1 is annular, and several hot walls 1 not of uniform size are nested layer by layer Cluster；It has been provided between each adjacent hot wall 1 and has supported the pressure-resistant channel strips 6 or fin for acting on and facilitating fluid to pass through 16；Channel strips 6 outside all hot walls 1 or the fluid side of fin 16 are divided into multiple regions, region includes heat absorption area and heat release zone, The remote heat exchange of the heat exchanging fluid contacted with hot wall 1 is realized by the phase change fluid in hot wall 1.

Specifically, the interconnection that the through hole or opening that the upper end of 1 inner supporting device of hot wall 2 opens up are formed walks gas phase (evaporation Fluid afterwards), the same interconnection that lower end opens up walk liquid phase fluid, if the inner supporting device 2 is phase unsteady flow in heat absorption area The passage of evacuator body, if in heat release zone being the passage that phase change fluid liquid phase falls.Understand, filled in inner support built in hot wall 1 The effect for putting 2 is the shunting for realizing gas phase and the fluid of liquid phase two, and also primarily serving support outside fluid in addition (namely needs to exchange heat Fluid) extruding to hot wall 1, prevent hot wall 1 from caving in.

Understand, due to hot wall 1 using slimming heat exchange partition 5 come reduce cost and raising heat exchange efficiency, then between hot wall 1 Need to strengthen support force, various forms of channel support bars and force-applied rectangular fin 16 can be used, on the one hand can improve and hold By the intensity of Fluid pressure, heat exchange area on the other hand can be expanded in limited bulk, as shown in Figure 7 is placed in annular hot wall Channel strips 6 between 1, channel strips 6 can also be placed between rectangle hot wall 1, channel support bar also as shown in Figure 6, the passage There is fin 16 in the passage of bar 6, it is to fill in one by one between hot wall 1, and can also release cleaning one by one.And in hot wall 1 Inner supporting device 2 as shown in Figure 2 and Figure 4, it has through hole similar to rectangular fin 16, simply the upper and lower of fin 16, facilitates hot wall 1 Interior phase change fluid left and right horizontal flowing, when hot wall 1 is as heat absorbing element, phase change fluid evaporation is along shown in Fig. 2 or Fig. 4 The groove that is formed of interlude 3 flow up, each groove gaseous fluid is all converged in the communicating passage device of angle side, to putting Gaseous fluid in thermal region communicating passage device is diverted to again discharges latent heat as in condensation 1 each groove of hot wall, discharges latent heat Liquid phase fluid afterwards converges in the communicating passage of inferior horn side, and flows to heat sink region through this again；Such as Fig. 2 (a) and Fig. 4 (a) institutes The rectangular fin 16 shown not only acts as certain supporting role, and the passage of flowing up and down is also provided for phase change fluid, and on fin 16 Lower edge is not completely enclosed, it is possible to provide the space of phase change fluid bottom horizontal flow sheet；And Fig. 2 (b) and Fig. 4 (b) it is quite different it be whole Individual rectangular fin 16 is covered with its rectangle hot wall 1, and simply the upper and lower side 4 of fin 16 is provided with breach, can facilitate phase change fluid level stream It is dynamic.

Fig. 1 and Fig. 3 are refer to, single rectangle hot wall 1 or annular hot wall 1 complete following for internal phase change fluid relatively independently Without setting inlet and outlet during ring, without setting connecting pipe 7.Mutual disconnected rectangle hot wall 1 and annular hot wall 1, they There are evaporator section and condensation segment, this and existing heat pipe are similar.Axial heat pipe must be separated into endotherm section and heat release section, and radially hot Pipe heat release is absorbed heat outside die at heat pipe center, and single hot wall 1 is segmented into heat absorbing part and heat release part in the present invention, Can also single hot wall 1 be fully used as the hot wall 1 of heat absorption and the hot wall 1 of heat release, and annular hot wall 1 is single is used as heat absorption and (or puts Heat) hot wall 1 when can realize overlength distance exchange heat.

Fig. 5 (a) is refer to, each rectangle hot wall 1 or annular hot wall 1 are interconnected by pipeline 7 to complete internal phase transformation The circulation of fluid, heat is transmitted by phase transformation in the form of total tune.Fig. 5 (b) is refer to, needs one when forming 1 cluster of hot wall To pipeline 7, and it is that diagonally opposing corner arranges that top pipeline 7 is to walk gaseous fluid (after evaporation), and it is (cold that lower section pipeline 7 walks liquid phase up and down After solidifying) fluid, pipeline 7 is semicanal, and the through hole being connected with phase change fluid inlet and outlet is offered on the semicanal.According to changing for reality Hot device structure, the cross section of semicanal is that either rectangle (refer to Fig. 8 (b)) or one end are circular to semicircle (refer to Fig. 8 (a)) Remainder is semicircle (refer to Fig. 8 (c)).

Hot wall type heat exchanger proposed by the present invention can realize the multi-party bit flow of heat exchanging fluid.It refer to Fig. 1 (a), rectangle Hot wall 1 is placed vertically, and the inlet and outlet direction of phase change fluid is parallel with the setting direction of inner supporting device 2, in order to heat exchanging fluid Flow in the horizontal direction, which is suitable as the design of air conditioning terminal.Fig. 1 (b) is refer to, rectangle hot wall 1 is placed vertically, phase The inlet and outlet direction of fluid is vertical with the setting direction of inner supporting device 2, in order to which heat exchanging fluid vertically flows.Adopt Space is not only saved with vertical mode and is reduced and is taken up an area, and convenient maintenance and installation.

Preferably, the external device (ED) of the external disposal phase change fluid of pipeline 7, external device (ED) include being used for heating phase change fluid At least one of defrosting device, compressor or circulating pump.Carried by external device (ED)s such as compressor or circulating pumps for phase change fluid The power of confession can realize that overlength distance exchanges heat.

Preferably, the similar annular hot wall 1 of several shapes surrounds vesica piscis, round rectangle ring (refer to Fig. 3 (a)) Or preset shape, hot wall type heat exchanger are provided centrally with the ring that shapes, setting ring periphery has a circle circle similar to its shape Annular hot wall 1, all hot walls 1 and affiliated channel strips 6 or fin 16 are all risen by the lock ring of heavy wall ring 8 of the allowable stress of outside Come.Because the channel strips 6 or fin 16 that are mutually supported between annular hot wall 1 can be eventually transferred to its internal pressure outermost heavy wall Ring 8, annular hot wall type heat exchanger have a larger pressure-resistant degree in the presence of outermost heavy wall ring 8, and outermost heavy wall ring 8 Wall thickness can be with larger without influenceing heat exchange efficiency.

Fig. 3 (b) is refer to, expansion folding 9 is additionally provided with annular hot wall 1.Due to its internal flow expanded by heating, in order to anti- Only expand and cause the damage of hot wall 1, therefore there is provided the folding that can be stretched, expansive force may finally be delivered to outermost heavy wall Ring 8.

Fig. 9 is refer to, hot wall type heat exchanger also includes housing the shell 10 of annular hot wall 1, is detachably connected with shell 10 Upper capping 11 and lower capping 12 with 10 non-dismountable connection of shell, shell 10 be connected to form cavity volume with lower capping 12 13, it is lower to cover the inlet and outlet passage that cleaning fluid side is provided with 12, and one of passage covers 12 and heat exchanger through lower Center cavity connection.The hot wall type heat exchanger that the present embodiment proposes can realize both sides cleaning operationally, and this is due to heat Wall type heat exchanger can be designed to that capping 11 is not connected to the circulating line with phase change fluid heat exchange, be passed in and out when cleaning side liquid When Flow-rate adjustment is appropriate, fluid spilling is not just had, can go out blowdown by non-dismountable end socket low level under during cleaning.Previous is more Inconvenient during 16 heat exchanger cleaning heat exchange 5 dirt of partition of layer coaxial cylinders fin, fin 16, which always has one, when leading to big gun to wear Cross, especially manufacture difficulty is big, always occur fin 16 and partition be difficult it is close be connected cause thin-walled compression after burst：And this ring Shape hot wall type heat exchanger can realize the high efficiency of plate type heat exchanger, while can realize the voltage endurance of shell-and-tube heat exchanger again, Because annular thin wall nested layer by layer is provided with expansion folding 9 inside it, its internal fluid pressure can be allowed to be delivered to by expanding folding 9 Outermost stress heavy wall ring 8.This heavy wall ring 8 can with lock ring its internal each hot wall 1 and affiliated channel strips 6 or fin 16, rectangle The same outer layer of hot wall type heat exchanger uses the pressure-resistant clamping plate of suitable depth, there is the support channel strips 6 of stress between hot wall 1.Small volume Space-consuming is few comparable to plate type heat exchanger, cleans and is more convenient than plate type heat exchanger and shell-and-tube heat exchanger, while has started existing What all kinds of heat exchangers can not all be realized leads to the precedent of the big gun cleaning heat exchange technology of partition 5 in operation, and realizes like never before The application of numerous field of heat exchange, its coverage rate exceed any major class heat exchange equipment species, similar heat pipe heat exchanging mode It is applied in more more extensive fields and goes.

Now illustrate annular heat wall type heat exchanger with specific reference to Fig. 9, the annular hot wall type heat exchanger include annular hot wall 1, Channel strips 6 and heavy wall ring 8, the annular hot wall 1 in Fig. 9 can be the annular hot wall 1 as shown in Fig. 3 (b), channel strips 6 or fin 16 as shown in figure 4, phase change fluid split channel 14 and phase change fluid busway 15 are arranged at the diagonal position of heat exchanger, they All it is that the channel strips 6 in this communicating passage bottom need to close, to prevent phase unsteady flow using the semicanal communicating passage as shown in Fig. 8 (c) The leakage of body, (or heat release) fluid that absorbs heat is from the central tube of heat absorption (or heat release) fluid outlet channels inflow heat exchanger, through hot wall 1 Cavity volume 13 is flowed into after heat exchange, is finally flowed out from heat absorption (or heat release) fluid outlet channels of lower end, the hot wall type heat exchanger can To realize that overlength distance exchanges heat, the phase change fluid in its annular hot wall 1 can transport phase change fluid by compressor or circulating pump The place delivered to farther out carries out heat exchange with heat release (or heat absorption) fluid, and this is more more meaningful than the existing remote heat exchange of heat pipe A bit, in fact heat recipient fluid and heat release fluid they can be with wide apart, heat exchange is by annular hot wall 1 between them The evaporation of phase change fluid transmits heat with condensation, this evaporator for being well suited for making central air-conditioning and condenser and steam power plant Condenser, realize and efficiently exchanged heat as plate type heat exchanger, and it is also more convenient than shell-and-tube heat exchanger to clean incrustation scale because When opening the cleaning of capping 11 thereon, it is not necessary to the exits and entrances valve of heat exchanging fluid is completely closed, simply adjusts its imported valve Opening degree do not allow its fluid to overflow (can to discharge by its underpart blowoff valve, and timely amount of makeup water), cleaning process can be with The operation of unit is not influenceed, and also will not unit surrounding enviroment be caused with dirty situation.

Several rectangle hot wall type heat exchangers presented below.

Figure 10 is refer to, to realize the first embodiment of the hot wall type heat exchanger to be exchanged heat between liquid-to-air.Heat exchanger One end have it is a bit of be separated into liquid heat absorption (or heat release) containment volume A, and by chamber shell wrap up with it is less heat absorption (heat release) Region area corresponds to larger heat release (heat absorption) region B areas (because Air Heat Transfer Coefficient small, it is necessary to larger heat exchange area), To adapt to the application in more wide spectrum, it can be used as cooling heat radiator, such as surface cooler, tail end of central air conditioner, radiator Deng specifically, gaseous fluid enters left end from the right-hand member in B areas and gone out, and the fin 16 between adjacent hot wall 1 is air heat-exchange fluid fin 16, the side of the fin 16 is additionally provided with strip of paper used for sealing, so constitutes air side fins and the strip of paper used for sealing of its both sides arranges alternately for one With rectangle hot wall multigroup phase change heat exchange device for forming entirety arranged side by side, the device has sub-fraction to be placed in A areas, and is held by the region Product cavity 17 is wrapped, it will be understood that the volume chamber 17 housed with the fluid of gaseous fluid heat exchange, the appearance are provided with A areas Being additionally provided with product cavity 17 inside dismountable capping 18,17 has rectangle hot wall and fin, the hot wall type heat exchanger be used for The fluid side pressure drop of gaseous fluid heat exchange is very small, can largely save the power of circulating pump, and without the anxiety of blocking, while Convenient cleaning, can be used as the condenser of steam power plant and nuclear power plant, can greatly improve generating efficiency, and fault rate is also greatly reduced, Operational reliability strengthens, and is also used as heat source tower, and cheap heat energy, it is long-standing can to eradicate defrost in the world in absorption air Problem, phase change fluid is set to obtain hot increasing enthalpy because it can connect the communicating passage of hot wall 1 by heater, easily Frostization on the outside fin 16 of hot wall 1 is gone, or even the heat energy of defrost is also unlikely to waste, also unlike existing all defrost skills Art can all have influence on the experience of heating, defrost, or the time of delay heat production need be gone from indoor acquisition heat, either reversely Defrost is run, it is all to need to pay very big Energy Consumption Cost still to directly heat defrosting method, it appears lose more than gain, Severe cold winter might as well be calculated using Boiler heating.Because fin 16 is perpendicular to ground, and heat can be from fin 16 or partition The rapid root for being delivered to frost, not waiting and all melt away, frost can fall, and the steam latent heat in air is also just used, this It is a kind of defrost technical method very to one's profit.Configuration heating volume chamber is simultaneously connected on the communication apparatus of hot wall 1, can make phase change fluid In heat transfer to the fin 16 between hot wall 1 and hot wall 1, heat is scattered to room for heating, phase change fluid is again It is condensed into liquid and is back to heating volume intracavitary again, its structure is more compact attractive in appearance, is adapted to do indoor radiating sheet devices etc..

Figure 11 is refer to, the second embodiment of hot wall type heat exchanger to be exchanged heat between liquid-to-air can be achieved.Chilled water (or warm matchmaker's water) enters heat release (or heat absorption) region enclosed volume cavity 17 from entering chilled water 19 (or warm matchmaker's water inlet), with square After shape hot wall 1 is exchanged heat, flowed out from refrigerant water out 20 (or warm matchmaker's water out), condensation-water drain 21 of the condensed water from lower end Outflow, the hot wall type heat exchanger are additionally provided with centrifugal blower 22, the centrifugal blower 22 and the air outlet passage set on heat exchanger 23 coordinate to accelerate the circulation of air, and the heat exchanger substitutes existing fan coil can be greatly reduced master as tail end of central air conditioner Function consumes.

Figure 12 is refer to, to realize an embodiment of the hot wall type heat exchanger to be exchanged heat between liquid and liquid, C fluids and D Fluid is exchanged heat at a distance, can both sides cleaned, alternative existing plate type heat exchanger and shell-and-tube heat exchanger.Can also be according to Method is designed to three fluid heat transfers accordingly, and one is heat absorption area, or two are heat release zones.

Figure 13 is refer to, to realize an embodiment of the hot wall type heat exchanger to be exchanged heat between air and air, it includes square The pipeline 7 of the cluster of shape hot wall 1, the heat exchange fin 16 being arranged between adjacent hot wall 1 and each hot wall 1 of connection.Room air is from changing Region below hot device enters, and after the heat exchange of hot wall 1, is discharged from the region of top, upper and lower region passes through cold and hot demarcation strip Separate, it is special suitable that this heat exchanger is used as new blower fan.

From the above it can be seen that hot wall type heat exchanger has outside the advantage of heat exchange of heat pipe, also at least there is advantages below：(1) it is single Heat exchange area is more much bigger than heat exchange of heat pipe in the volume of position, it appears and it is compacter, because empty shared by the wind-collecting pipe of equal surface Between be more than hot wall 1；(2) it is more extensive using field, it is adapted to vertical heat exchanging fluid, level, the various streams of oblique angle multiple directions The heat exchange of dynamic form, need to make the axially or radially selection of heat pipe rather than heat exchange of heat pipe and unsuitable oblique angle is placed；(3) Either changing between liquid and liquid or gas and gas or liquid and gas or liquid-to-air or gas and air Heat, hot wall type heat exchanger can all show efficient and economic use, and existing various heat exchange of heat pipes can not be economically complete The full application for substituting plate type heat exchanger, shell-and-tube heat exchanger, plate-fin heat exchanger and tubular type finned heat exchanger in many fields； (4) internal phase change fluid shunting is more smooth, because its internal two phase flow is difficult mixing, is walked without resistance, each of which between phase border Road and evaporation road are condensed, evaporative condenser phase change fluid circulation rate can be accelerated；(5) the lateral fluid resistance of hot wall 1 is less than heat pipe, its Pressure drop is again smaller than heat pipe；(6) annular hot wall type heat exchanger its pressure-resistant degree in the presence of outermost heavy wall ring 8 is more than existing heat pipe Heat exchanger, its internal pressure can be eventually transferred into due to having the channel strips 6 mutually supported or fin 16 between annular hot wall 1 Outermost heavy wall ring 8, and annular hot wall 1 can also set expansion folding 9, and its internal pressure is transmitted to heavy wall by expansion fashion Ring 8, and the wall thickness of outermost heavy wall ring 8 can be with larger without influenceing heat exchange efficiency；(7) hot wall 1 combines cleverer than heat pipe combination Work is various, the hot wall type heat exchanger for more conforming to application scenarios can be designed according to actual conditions, it will than heat pipe using diversity Much more, the heat exchanger that especially rectangle hot wall 1 is formed is more advantageous, because it is not necessarily required to single hot wall 1 one Point it is put into heat absorption area and does evaporator section use, and another part is placed on heat release zone and does condensation segment use, but can be put so that single hot wall 1 is overall In heat absorption area or condensing zone, and absorb heat area and heat release zone is segmented into multiple regions, the existing heat exchange of heat pipe of this point It can not obtain, heat exchange of heat pipe must be that one section of each heat pipe is placed in heat release zone, and another section is placed in heat absorption area's (its Inside is formed evaporator section and condensation segment), and this two sections two regions formed are mutually isolated also relatively difficult, easily Generation blowby, if heat pipe outer wall has fin, it is extremely difficult that it, which is divided into heat absorption area and heat release region, with metal material, and being will Pay the region pressure difference of many processing costs, especially two it is bigger in the case of, even more embarrassed important task；(8) cost specific heat Pipe is low, according to practical application scene can will heat exchange partition 5 be thinned, existing heat exchange of heat pipe be difficult to by comparison, because For the pressure-bearing of hot wall 1 served as by outermost heavy wall ring 8 or both ends heavy wall stress clamping plate, need each heat pipe material rather than heat pipe Thickness is expected to serve as pressure-bearing, so much less is wanted in the consumption of the metal material of hot wall 1, pressure-resistant degree can also increase；(9) equipment is tieed up Shield is more convenient than existing heat pipe, looks for leakage point easy, and welding mending-leakage is convenient, and extraction incoagulable gas is also easy, phase change fluid note Entering disposably to be performed integrally, and can also realize the design cleaned in operation；(10) heat pipe can exchange heat at a distance, and Hot wall 1 can not only exchange heat at a distance, and can also realize that overlength distance exchanges heat by means of compressor or circulating pump；(11) Heat pipe is difficult to that evaporating area (thermal source) is multiple regions or condensing zone (low-temperature receiver) is multiple regions, and the rectangle hot wall type that is connected changes Hot device is then easily achieved multiple evaporating areas or multiple condensing zones；(12) sealing factor can be more much lower than heat pipe, and dust stratification is not as warm Pipe is so obvious, because hot wall 1 and fin 16 are all perpendicular to ground.

The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this Under the design of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/it is used in indirectly He is included in the scope of patent protection of the present invention related technical field.
