Prenosnik toploteHeat exchanger

Izum v okviru strojništva spada na področje ogrevanja, namreč k toplotnim izmenjevalnikom, pri katerih za prenos toplote predvidena medija ne prideta v neposreden stik, pri čemer gre za medija, ki sta v stiku vsak s svojo steno vsakokrat pripadajočega ploščato zasnovanega stacionarnega voda, in pri čemer so vodi drug glede na drugega razporejeni bodisi vzporedno ali pod določenim kotom.The invention in the field of mechanical engineering belongs to the field of heating, namely heat exchangers, in which the intended media do not come in direct contact with the medium, which is a medium in contact with each wall of the respective flat-design stationary line, and the lines being arranged relative to one another either parallel or at a certain angle.

Pri tem je izum osnovan na problemu, kako zasnovati preprost in cenen prenosnik toplote, ki bo omogočal prehod toplote s primarnega plinastega medija na sekundami plinast medij ali obratno, pri čemer naj bi bil tovrsten prenosnik toplote primeren za delovanje v vsaj v temperaturnem območju sobnih temperatur in običajnih zunanjih temperatur atmosferskega zraka in torej za uporabo še zlasti na področju prezračevanja zgradb oz. bivalnih prostorov.The invention is based on the problem of how to design a simple and inexpensive heat exchanger that will allow the transfer of heat from the primary gaseous medium to the gaseous medium for seconds or vice versa, whereby such heat exchanger is suitable for operation in at least the temperature range of room temperatures. and normal ambient air temperatures, and therefore for use especially in the field of ventilation of buildings or. living quarters.

Na področju prenosnikov toplote so znane številne rešitve. V kontekstu pričujočega izuma gre za prenosnik toplote, ki obsega dva tokokroga za pretok dveh med seboj ločenih plinastih medijev z različnima temperaturama, namreč primarni tokokrog za pretok primarnega plinastega medija in sekundami tokokrog • · · ·Many solutions are known in the field of heat exchangers. In the context of the present invention, it is a heat exchanger comprising two circuits for the flow of two interconnected gaseous media with different temperatures, namely a primary circuit for the flow of the primary gaseous medium and seconds of the circuit.

za pretok sekundarnega plinastega medija, pri čemer v območju tovrstnega prenosnika toplotni tok prehaja s primarnega medija na sekundami medij ali obratno. Vsak od omenjenih tokokrogov načeloma obsega vstopno in izstopno območje primarnega tokokroga ter vstopno in izstopno območje sekundarnega tokokroga, pri čemer se v vsakem izmed omenjenih območij zbira medij pred vstopom v prenosnik oz. po izstopu iz njega.for the flow of the secondary gaseous medium, whereby in the region of such a transmitter the heat flow passes from the primary medium to the medium for seconds or vice versa. Each of said circuits generally comprises the inlet and outlet area of the primary circuit, and the inlet and outlet area of the secondary circuit, in which each medium collects media prior to entering the laptop or computer. after exiting it.

Tako je npr. v DE 10 2006 016839 Al opisan prenosnik toplote, kakršnega npr. v vozilih uporabljajo za uravnavanje temperature zraka v potniškem prostoru, načeloma pa je tovrsten ali smiselno popolnoma podoben prenosnik toplote uporaben tudi za uravnavanje temperature hladilnega medija pri motorju z notranjim zgorevanjem. Pri tovrstnem prenosniku toplote je na voljo zelo razvejan in z izrazito razčlenjeno površino zasnovan in smiselno v eni ravnini razporejen primarni tokokrog, po katerem se med vstopnim in izstopnim kolektorjem pretaka primarni medij, npr. voda ali druga ustrezna tekočina. Sekundami tokokrog poteka skozi množico prehodov v območju omenjenega primarnega tokokroga, ki potekajo v smeri pravokotno glede na ravnino omenjenega primarnega tokokroga. Omenjen primarni tokokrog sestoji iz množice med seboj v smislu omogočanja pretoka medija povezanih kovinskih cevi, ki so po izbiri opremljene z rebri za povečanje površine, ki je v stiku s sekundarnim medijem. Načeloma obstoji tudi možnost, da tovrsten prenosnik sestoji iz razmeroma tenke kovinske folije ali iz pločevine, ki je preoblikovana na tak način, da so po preoblikovanju na voljo ustrezno zaprti cevasti in ravninsko razporejeni kanali za pretok primarnega medija ter med njimi razporejeni prehodi za pretok sekundarnega medija. V obeh primerih je izdelava tovrstnega prenosnika izjemno zapletena in terja velika vlaganja v preoblikovalna orodja in izdelovalne linije. Po drugi strani je pretok primarnega medija po primarnem tokokrogu možno razmeroma natančno nadzirati in krmiliti, • ·Thus, e.g. in DE 10 2006 016839 A heat exchanger such as e.g. They are used in vehicles to regulate the air temperature in the passenger compartment, but in principle, this or meaningfully similar heat exchanger is also useful for controlling the temperature of the cooling medium in an internal combustion engine. In such a heat exchanger, a highly branched and highly divided surface is designed and designed in a single plane to form a primary circuit through which the primary medium flows between the inlet and outlet manifolds, e.g. water or other suitable liquid. Seconds of a circuit pass through a plurality of transitions in the area of said primary circuit, extending in a direction perpendicular to the plane of said primary circuit. Said primary circuit consists of a plurality of one another in terms of allowing the flow of media of connected metal tubes, which are optionally provided with ribs to increase the surface in contact with the secondary medium. In principle, there is also the possibility that such a laptop consists of a relatively thin metal foil or sheet metal, which is transformed in such a way that, after the transformation, duly sealed tubular and planar channels for the flow of the primary medium and spaced transitions for the flow of the secondary are available media. In both cases, making this kind of laptop is extremely complex and requires a lot of investment in transformation tools and production lines. On the other hand, the flow of the primary medium through the primary circuit can be controlled and controlled relatively precisely, • ·

medtem ko se pretok sekundarnega medija skozi omenjene prehode vrši bolj ali manj stihijsko, tako daje posledično tudi intenziteta prehoda toplote s primarnega medija na sekundami medij ali obratno razmeroma nepredvidljiva.while the flow of the secondary medium through said transitions is made more or less spontaneously, consequently the intensity of the heat transfer from the primary medium to the seconds is also relatively unpredictable.

Podobno je v WO 2010/013608 opisan ploščat prenosnik toplote, ki sestoji iz satju podobne ploščate tvorbe. S tem je v prenosniku na voljo množica med seboj vzporednih prehodov, od katerih določeni prehodi predstavljajo del primarnega tokokroga za prehod primarnega medija, njim sosednji prehodi pa del sekundarnega tokokroga za prehod sekundarnega medija. Tudi tak prenosnik toplote ja razmeroma zahteven v pogledu same izdelave, povrhu vsega pa je izjemno zapletena tudi zasnova vsakokratnega vstopnega in izstopnega ko lektorja primarnega in sekundarnega tokokroga, saj mora biti vsak od kolektorjev natančno usklajen s pripadajočimi prehodi, ki so sicer med seboj razmaknjeni, obenem pa vsi skupaj formirajo primarni oz. sekundami tokokrog.Similarly, WO 2010/013608 describes a flat heat exchanger consisting of a honeycomb-like flat structure. Thereby, the laptop provides a plurality of parallel transitions, of which certain transitions form part of the primary circuit for the passage of the primary medium and adjacent transitions form part of the secondary circuit for the transition of the secondary medium. Such a heat exchanger is also relatively demanding in terms of production itself, and on top of that the design of the inlet and outlet coils of the primary and secondary circuits is extremely complex, since each of the collectors must be closely aligned with the corresponding transitions, which are otherwise spaced apart, at the same time, they all together form the primary or seconds of circuit.

Še nadalje je v GB 1,056,582 opisan prenosnik toplote, ki je konceptualno podoben tistemu po DE 10 2006 016839 Al, čeprav je zasnovan v bistvu cilindrično. Tudi v tem primem namreč primarni tokokrog tvorijo med seboj sicer vzporedno razmaknjeni, vendar v notranjosti cilindričnega volumna razporejeni cevasti vzdolžni prehodi, ki tako tvorijo v aksialni smeri prenosnika potekajoč primarni tokokrog, v katerem je medij razmeroma dobro nadzorovan in upravljan. Pretok sekundarnega medija skozi sekundami tokokrog, ki poteka v radialni in/ali cirkulami smeri, in posledično prehod toplote s primarnega na sekundami tokokrog ali obratno, je celo v primem, če je prenosnik toplote obdan z od primarnega tokokroga radialno odmaknjenim plaščem, razmeroma težko kontrolirati z dovolj veliko natančnostjo.GB 1,056,582 further describes a heat exchanger conceptually similar to DE 10 2006 016839 Al, although it is essentially cylindrical. In this case, too, the primary circuit is otherwise spaced apart from one another, but tubular longitudinal crossings are arranged inside the cylindrical volume, thus forming a primary circuit in the axial direction of the laptop, in which the medium is relatively well controlled and controlled. The flow of the secondary medium through the seconds of the circuit running in the radial and / or circular direction, and consequently the heat transfer from the primary to the second circuits or vice versa, is even relatively difficult to control even if the heat exchanger is surrounded by a radially spaced sheath from the primary circuit. with enough precision.

Na področju prezračevanja so znani tudi preprostejši prenosniki toplote, ki sestojijo iz zgubanega papirja, v katerem so na voljo kanali za pretok primarnega in sekundarnega plinastega medija. Problem tovrstnih prenosnikov predstavlja že samo vzdrževanje oblike med njihovo uporabo, obenem pa so povezani z razmeroma velikimi pretočnimi upori, za nameček pa je tudi učinkovitost samega prenosa toplote razmeroma nizka.In the field of ventilation, simpler heat exchangers are also known, consisting of folded paper which has channels for the flow of primary and secondary gaseous media. The problem with these types of laptops is the maintenance of the form itself during their use, but at the same time they are associated with relatively high flow resistances, and in fact the efficiency of the heat transfer itself is relatively low.

Izum se nanaša na prenosnik toplote, ki je predviden za pretok dveh med seboj ločenih plinastih medijev, namreč primarnega plinastega medija in sekundarnega plinastega medija.The invention relates to a heat exchanger designed to flow two gaseous media, namely a primary gaseous medium and a secondary gaseous medium.

Po izumu je predlagan prenosnik toplote, ki sestoji iz vsaj dveh votlih večkanalnih panelov, od katerih je vsaj eden predviden za pretok primarnega plinastega medija, vsakokrat sosednji pa je predviden za pretok sekundarnega plinastega medija., vsakokraten votel večkanalni panel prednostno predstavlja kot plošča zasnovan ali plošči podoben, smiselno dvodimenzionalen konstrukcijski element, katerega debelina je bistveno manjša od njegove širine in/ali dolžine, pri čemer omenjeni panel obsega niz v njegovi vzdolžni ali prečni smeri vsaj približno vzporedno potekajočih cevastih kanalov, ki so vsak zase obdani in med seboj ločeni z razmeroma tenko steno, katere debelina je znatno manjša od vsaj ene od dimenzij svetline prečnega preseka kanala.According to the invention, a heat exchanger consisting of at least two hollow multichannel panels is proposed, at least one of which is provided for the flow of the primary gaseous medium, and each adjacent is provided for the flow of the secondary gaseous medium. a panel-like, meaningfully two-dimensional structural member whose thickness is substantially less than its width and / or length, said panel comprising a string in its longitudinal or transverse direction of at least approximately parallel tubular ducts, each surrounded and separated by a relatively thin wall whose thickness is substantially less than at least one of the dimensions of the channel cross-section luminance.

Pri tem je prečni presek kanalov v vsaj enem izmed panelov po izbiri lahko kvadraten, pravokoten, trapezen, trikoten ali tudi drugače oblikovan. Omenjeni paneli so prednostno ekstrudirani in sestojijo iz termoplastičnega polimernega materiala, še zlasti iz polipropilena posebne gostote, ki je primeren za uporabo v temperaturnem območju med 20°C in 120°C. Pri tem so vsakokrat razpoložljivi • · • · · · paneli med seboj lahko bodisi nerazstavljivo povezani, še zlasti s pomočjo toplotno prevodnega lepila, ali pa po izbiri razstavljivo povezani, in sicer na tak način, da so ob zagotavljanju ustreznega medsebojnega pritiska, ki zadostuje vsaj za odpravo zračnosti med njimi, obdani z okrovom.The cross-section of the channels in at least one of the panels may optionally be square, rectangular, trapezoidal, triangular or otherwise shaped. Said panels are preferably extruded and consist of thermoplastic polymeric material, in particular of special density polypropylene, suitable for use in the temperature range between 20 ° C and 120 ° C. In each case, the available panels may be either individually interconnected, in particular by means of thermally conductive adhesive, or optionally disassembled, in such a way that, while providing adequate mutual pressure, sufficient at least to eliminate the playfulness between them, surrounded by a casing.

Nadalje je pri eni od možnih izvedb prenosnika toplote po izumu en votel večkanalni panel, ki je predviden za pretok primarnega plinastega medija, razporejen med dvema paneloma, ki sta predvidena za pretok sekundarnega plinastega medija. Pri tem pa kanali v votlem večkanalnem panelu, kije predviden za pretok primarnega plinastega medija, lahko potekajo v smeri prečno ali po izbiri poševno pod vnaprej določenim kotom glede na smer poteka kanalov ali celo v smeri poteka kanalov v vsakem izmed obdajajočih ga panelov, ki sta predvidena za pretok sekundarnega plinastega medija.Further, in one of the possible embodiments of the heat exchanger according to the invention, one hollow multichannel panel intended for the flow of the primary gaseous medium is arranged between two panels intended for the flow of the secondary gaseous medium. However, the channels in the hollow multi-channel panel intended for the flow of the primary gaseous medium may extend in the direction of the transverse or optionally obliquely at a predetermined angle with respect to the direction of channels or even in the direction of channels in each of the surrounding panels, which are both designed for secondary gas flow.

Pri nadaljnji izvedbi prenosnika pa sta med vsakokrat sosednjima paneloma vstavljena vsaj dva med seboj razmaknjena distančnika, ki skupaj z omenjenima paneloma tvorita cevast kanal.In the further embodiment of the laptop, however, at least two spaced spacers are inserted between the two adjacent panels, which together with the said panels form a tubular channel.

• · • · · ·• · · · ·

Prenosnik toplote 1 po izumu je predviden za pretok dveh med seboj vseskozi ločenih plinastih medijev, namreč primarnega plinastega medija M_p in sekundarnega plinastega medija M_s, pri čemer omenjeni prenosnik 1 sestoji iz vsaj dveh votlih večkanalnih panelov 11, 11'; 12, 12', od katerih je vsaj eden predviden za pretok primarnega plinastega medija M_p, vsakokrat sosednji pa za pretok sekundarnega plinastega medija M_s.The heat exchanger 1 according to the invention is provided for the flow of two gaseous media, namely primary gaseous medium M _p and secondary gaseous medium M _s , with each other, said transducer 1 consisting of at least two hollow multichannel panels 11, 11 '; 12, 12 ', at least one of which is provided for the flow of the primary gaseous medium M _p , and each adjacent for the flow of the secondary gaseous medium M _s .

Pri tem izraz »votel večkanalni panel« označuje kot plošča zasnovan ali plošči podoben, smiselno dvodimenzionalen in prednostno iz termoplastičnega polimernega materiala sestoječ konstrukcijski element, katerega debelina je bistveno manjša od njegove širine in/ali dolžine, pri čemer omenjeni panel obsega niz v njegovi vzdolžni ali prečni smeri vsaj približno vzporedno potekajočih cevastih kanalov, ki so vsak zase po svojem celotnem obodu obdani in med seboj ločeni z razmeroma tenko steno, in katerih prečni preseki, ki so v splošnem kvadratni ali pravokotni ali trikotni ali trapezni ali tudi drugače oblikovani, so lahko med seboj enaki ali različni.The term "hollow multi-channel panel" refers to a panel designed or panel-like, meaningfully two-dimensional and preferably thermoplastic polymer material consisting of a structural element whose thickness is substantially less than its width and / or length, said panel comprising a string in its longitudinal or transverse directions of at least approximately parallel tubular ducts, each enclosed and separated by a relatively thin wall throughout their entire circumference, and whose cross-sections, which are generally square or rectangular or triangular or trapezoidal or otherwise shaped, are they may be the same or different.

Na Sl. 1 je ponazorjen prenosnik toplote 1, ki predstavlja sklop med seboj nerazstavljivo povezanih votlih večkanalnih panelov 11, 1Γ; 12, 12, ki so na skici prikazani v navzkrižni razporeditvi, tako da kanali panelov 11, 11' za pretok primarnega plinastega medija M_p potekajo v smeri prečno glede na kanale panelov 12, 12' sekundarnega plinastega medija M_s, s čimer je dovajanje o odvajanje vsakega od medijev M_p, M_s, lahko izvedeno na povsem preprost način. V splošnem je možna tudi različica, pri kateri kanali panelov 11, 11' za pretok primarnega plinastega medija M_p potekajo poševno pod vsakokrat izbranim kotom glede na kanale panelov 12, 12' sekundarnega plinastega medija M_s, ali celo v isto smer kot kanali panelov 12, 12' sekundarnega plinastega medija M_s. N tem primeru so paneli 11, 1Γ; 12, 12' izvedeni iz polipropilena posebne gostote, kije primeren za uporabo v temperaturnem območju med 20°C in 120°C, tovrstne panele pa je možno med seboj zlepiti s pomočjo toplotno prevodnega lepila.In FIG. 1 is an illustrated heat exchanger 1 which represents an assembly of interconnected hollow multi-channel panels 11, 1Γ; 12, 12, which are shown in the cross-sectional view such that the channels of the panels 11, 11 'for the flow of the primary gaseous medium M _p extend in a direction transverse to the channels of the panels 12, 12' of the secondary gaseous medium M _s , thereby supplying o The separation of each of the media M _p , M _s can be done in a very simple way. In general, a variant is also possible in which the channels of the panels 11, 11 'for the flow of the primary gaseous medium M _p flow obliquely at the angle chosen at each time with respect to the channels of the panels 12, 12' of the secondary gaseous medium M _s , or even in the same direction as the channels of the panels 12, 12 'of the secondary gaseous medium M _s . In this case, panels are 11, 1Γ; 12, 12 'made of special density polypropylene, suitable for use in the temperature range between 20 ° C and 120 ° C, and such panels can be bonded to one another by means of heat-conducting adhesive.

Na Sl. 2 je ponazorjena osnovna različica panela 11, ki kot rečeno lahko sestoji iz polipropilena posebne gostote, ki je primeren za uporabo v temperaturnem območju med 20°C in 120°C, izdelati pa gaje možno npr. z ekstrudiranjem. Zgolj v ilustrativne namene in brez vsakršne omejitve je možno pri širini svetline v danem primeru glede na prečni presek pravokotno oblikovanih kanalov, ki znaša približno 10 mm, izbrati debelino stene velikostnega reda 1 mm.In FIG. 2 is an exemplary basic embodiment of panel 11, which, as said, may consist of special density polypropylene suitable for use in the temperature range between 20 ° C and 120 ° C and may be manufactured e.g. by extrusion. For illustrative purposes only, and without any limitation, it is possible to choose a wall thickness of about 1 mm in the case of a width of luminosity, depending on the cross-section of rectangular grooves of approximately 10 mm.

Na Sl. 2 je ponazorjena nadaljnja izmed možnih izvedb panela 11, pri kateri so kanali na voljo s trikotnim prečnim presekom.In FIG. 2 is a further illustration of a possible embodiment of the panel 11, wherein the channels are provided with a triangular cross-section.

Za razliko od prej opisane izvedbe po Sl. 1, pri kateri so paneli 11, 1Γ; 12, 12' med seboj nerazstavljivo povezani, je na Sl. 4 ponazorjena izvedba, pri kateri so paneli 11, 12 med seboj razstavljivo povezani s pomočjo ustreznega okrova 2 ali drugih neprikazanih povezovalnih elementov, s čimer se je v procesu izdelave prenosnika 1 toplote po izumu možno izogniti zamudnemu lepljenju. Pri tem gre spet lahko za sklop panelov 11, 11', 12, 12', kakršen je prikazan na Sl. 1, v vseh predhodno opisanih možnostih in kombinacijah poteka samih kanalov, pri čemer je zaradi zagotavljanja primerne učinkovitosti prenosa toplote s primarnega plinastega medija M_p na sekundami plinasti medij M_s, ali potrebno zagotoviti ustrezen stik med vsakokrat sosednjima paneloma 11, 1Γ; 12, 12', kar pomeni, daje potrebno panele 11,1 1Γ; 12, 12' pritisniti drugega proti drugemu, kar se doseže s primemo vgradnjo v omenjen okrov 2 ali s pomočjo na skici neprikazanih povezovalnih elementov.In contrast to the embodiment described in FIG. 1, wherein the panels are 11, 1Γ; 12, 12 'are inextricably interconnected, in FIG. 4 illustrates an embodiment in which panels 11, 12 are interchangeably interconnected by means of a suitable housing 2 or other non-visible connecting elements, thereby avoiding delayed gluing in the process of manufacturing the heat exchanger 1 according to the invention. Again, this may be an assembly of panels 11, 11 ', 12, 12', as shown in FIG. 1, in all the channels and combinations described above, of the ducts themselves, in order to provide adequate heat transfer efficiency from the primary gaseous medium M _p for seconds to gaseous medium M _s , or to ensure adequate contact between each adjacent panels 11, 1Γ; 12, 12 ', which means that panels 11.1 1Γ are required; 12, 12 'to press against each other, which is accomplished by a suitable installation in said housing 2 or by the help of the connection elements not shown in the drawing.

Obenem pa omenjena izvedba po Sl. 4 ponazarja možnost, da se po potrebi število panelov 11, 1Γ; 12, 12' lahko reducira s tem, da se med dva vsakokrat sosednja panela 11, 11' vstavi vsaj dva med seboj ustrezno distančnika 31, 32, nakar je pretok primarnega plinastega medija M_p možno vzpostaviti npr. skozi vsakokrat razpoložljive panele 11, 1Γ, pretok sekundami plinasti medij M_s, pa skozi cevast vmesni prostor, kije omejen z vsakokrat sosednjima paneloma 11, 11' in vsakokrat sosednjima distančnikoma 31, 32.At the same time, said embodiment of FIG. 4 illustrates the possibility that the number of panels 11, 1Γ may be required; 12, 12 'can be reduced by inserting at least two corresponding spacers 31, 32 between the two adjacent panels 11, 11' at each end, after which the flow of primary gaseous medium M _p can be established e.g. through the available panels 11, 1Γ and the gaseous medium M _s through the tubular intermediate space bounded by the adjacent panels 11, 11 'and the adjacent spacers 31, 32 respectively.

Prenosnik toplote v skladu z navedenim značilnostmi se navzlic svoji preprostosti v smislu izdelave ter trdnosti in obstojnosti odlikuje po visoki pretočnosti ob majhnih pretočnih uporih, obenem pa tudi po učinkovitosti prenosa toplote, ki povsem izpolnjuje zahteve na področju klimatizacije in prezračevanja.The heat exchanger according to the above characteristics, despite its simplicity in terms of manufacture and strength and durability, is distinguished by its high flow rate with low flow resistance, as well as by its heat transfer efficiency, which fully meets the requirements in the field of air conditioning and ventilation.
