Po'dle konkretního provedení tohoto smíšeného výméníku jsou uvnitŕ bloku zploštelých trubek uspoŕádány trubky ve tvaru vlásenek pro obeh horké úžitkové vody. Smíšený výmeník je uspoŕádán takto :According to a particular embodiment of this mixed exchanger, hairpin-shaped tubes are arranged inside the block of flattened tubes for circulating hot service water. The mixed exchanger shall be organized as follows:
- rozmery uvedených zploštelých trubek a uvedených trubek pro obeh úžitkové vody jsou zvolený tak, že objem vody obsa žené v kruhovitém prostoru mezi télesem a trubkou ve tvaru vlá šenky je redukován co nejvíce ;- the dimensions of said flattened pipes and said plumbing pipes are selected such that the volume of water contained in the annular space between the body and the hairpin pipe is reduced as much as possible;
- blok výméníku sestává z množství desek uspoŕádaných preš sebe a na tvrdo pŕipájených na zploštelé topné trubky. Tyto trubky jsou spojený na jednom z koncú koleny vytvorenými ohybem téchto trubek do tvaru vlásenky bez sváru.- the exchanger block consists of a plurality of plates arranged on top of each other and brazed to flattened heating pipes. These tubes are connected at one of the ends of the knee by bending the tubes into a hairpin-like shape without a weld.
Na obrázcích a to zejména na obr. 1,2, 3 a 4 je možno videt, že topné zaŕízení, které je pŕedmétem tohoto vynálezu, zahrnuje první potrubí 2 pro ohrev vody ústŕedního topení a druhé potrubí 1 pro ohrev úžitkové vody.In the figures, in particular in FIG. 1, 2, 3 and 4, it can be seen that the heating device of the present invention comprises a first pipe 2 for central heating water and a second pipe 1 for domestic hot water.
Obrázek 1 znázorňuje obeh úžitkové vody ve tvaru šerie vlásenek _1_, které’ jsou vsunutý do zploštelých trubek 2 topného obehu, jež jsou rovnež uspoŕádány ve tvaru vlásenek.Figure 1 shows the circulating water in the form of twilight hairpins 1 which are inserted into flattened heating circulation pipes 2 which are also arranged in the shape of hairpins.
V horní části topného zaŕízení, kde je umísten predmet vy nálezu, má potrubí 2. topného obehu tvar . rady vlásenek ze zploštelých trubek jako je tomu u potrubí 2_, z nichž každá má pruŕez oválného tvaru, pŕičemž delší je osa horizontálni. Tyto trubky jsou spojený ha jednom z koncu koleny, :která se vytvorí ohybem téchto trubek.In the upper part of the heating device where the object of the invention is located, the pipe 2 of the heating circuit has the shape. a plurality of flattened hairpins, as in pipes 2, each having a cross-section of oval shape, the longer axis being horizontal. These tubes are joined at one end of the knee, which is formed by bending these tubes.
Potrubí úžitkové vody 1 se skládá trubek, které mají s výhodou kruhovitý pruŕez, uspoŕádaných uvnitŕ zploštelých trubek 2 topného obehu ve tvaru rady vlásenek, které jsou vytvorený ohybem téchto trubek kolmo k rovine dvakrát za sebou. Povrchová plocha výmeny tepla mezi dvema obehy smíše ného výmeníku je tímto zpúsobem zvetšena, jelikož všechnv ohyby jsou začlenený do topného obehu a nejsou umísteny mimo tento obeh.The service water pipe 1 consists of pipes, preferably having a circular cross-section, arranged inside the flattened heating circuit pipes 2 in the form of a series of hairpins, which are formed by bending these pipes perpendicular to the plane twice in succession. The surface area of the heat exchange between the two circuits of the mixed heat exchanger is increased in this way, since all the bends are incorporated into the heating circuit and are not located outside this circuit.
Umístení trubek úžitkové vody uspoŕádané do vlásenek uvnitŕ zploštelých trubek topného obehu se provede tak, aby nedošlo k fyzickému kontaktu mezi stenami trubek 1, a 2 a aby byl objem vody obsažený ve zbylém kruhovitém prostoru tak malý, jak je jen možno. Ďalším výsledkem tohoto uspoŕádání je skutečnost, že všechna energie pŕenášená topným obéhem se aplikuje na obeh úžitkové vody. Sestavování príslušných součástí probíhá takto : trubky 1_ ve tvaru vlásenek pro obeh úžitkové vody vybavené plastickým kroužkem 6 se vsunou do zploštelých trubek 2 topného vodního obehu, zatímco žebra X a kolektor 4. se uspoŕádají nad zploštelými trubkami 2. topného obehu a kryt 5 zcela uzavŕe celé zaŕízení. Tento kolektor zajištuje prutok topné kapaliny zrovná tak jako nepropust nost celého zaŕízení.The positioning of the service water pipes arranged in the hairpins inside the flattened heating circuit pipes is carried out in such a way that there is no physical contact between the walls of the pipes 1 and 2 and that the volume of water contained in the remaining circular space is as small as possible. A further result of this arrangement is that all the energy transmitted by the heating circuit is applied to the domestic water circuit. The assembly of the components takes place as follows: hairpin-shaped pipes 7 for domestic water circulation equipped with a plastic ring 6 are inserted into the flattened pipes 2 of the heating water circuit, while the fins X and the collector 4 are arranged above the flattened pipes 2 and the housing 5 completely the whole device. This collector provides a flow of heating fluid as well as the leakproofness of the entire plant.

Kolektor 4 zajištuje oba obehy výmeníku. Kolektor je na topný vodní obeh pŕipojen pájením. Dve mezisteny 7 zpúsobují, že topná voda nucene cirkuluje ve všech zploštelých trubkách. Tento kolektor se uzavírá krytem J5, který zaručuje nepro pustnost.The collector 4 secures both circuits of the heat exchanger. The collector is connected to the heating water circuit by soldering. The two partition walls 7 cause the heating water to circulate in all flattened pipes. This collector is closed by a cover J5, which guarantees tightness.
Pri alternativním provedení znázorneném na obr. 3 se kroužky vyrobené z plastického materiálu odolného vúči teplu a vlhkosti, s výhodou ze silikonu mohou vsunout na sadu trubekIn the alternative embodiment shown in FIG. 3, the rings made of a heat and moisture resistant plastic material, preferably silicone, can be inserted onto the tube set
- 5 obehu úžitkové vody ; tyto kroužky se nasunou na trubku 1 v pravidelných vzdálenostech. Toto zvláštni opatrení má dvojí výhodu ; zaprvé zajiŠtuje, aby nedošlo k žádnému kon taktu trubek se zploštelými trubkami 2 topného obehu a na druhé strane eliminuje vibrace hydraulického púvodu, ke kterým docházi v tomto typu instalací, když úžitková voda obihá v celé soustavé vlásenkovitých trubek.- 5 domestic water circulation; these rings are pushed onto the pipe 1 at regular intervals. This special measure has a twofold advantage; firstly, it ensures that there is no contact of the pipes with the flattened heating circuit pipes 2 and, on the other hand, it eliminates the vibrations of the hydraulic system that occur in this type of installation when the service water circulates throughout the hairpin system.
Z tohoto popisu vyplývá, že podie vynálezu lze uspoŕádat topné zarízení s perfektní výmenou tepla mezi dvema zabudova nými obehy topné a úžitkové vody v dúsledku značné povrchové plochy výmeny tepla, čehož se dosáhne vlásenkovitým vytvo rením ruzných obehu.According to this description, it is possible according to the invention to provide a heating system with perfect heat exchange between the two built-in circulation circuits of heating and service water due to the considerable surface area of heat exchange, which is achieved by hairpin formation of different circuits.
Neexistence kolen u obou obehu, zmena smeru dosažená ohybem trubek rúzných obehú zjednodušuje výrobu výmeníku, není zapotfebí pájení na tvrdo ani sváru a riziko netesností je vyloučeno.The absence of knees in both circuits, the change of direction achieved by bending the tubes of the various circulations simplifies the production of the heat exchanger, no brazing or welding is required and the risk of leaks is eliminated.
Je samozrejmé, že vynález není omezen pouze na popsaná a zobrazená provedení, ale že zahrnuje všechny varianty.It is understood that the invention is not limited to the embodiments described and illustrated, but that it encompasses all variations.
